Description

Peritoneal dialysis device

Technical Field

The present application relates to the field of medical devices, and more particularly, to a peritoneal dialysis device.

Background

Peritoneal dialysis is a process used to remove toxic substances and metabolites normally excreted by the kidneys, which helps regulate the fluid and dielectric balance. Peritoneal dialysis can be achieved by introducing a liquid for peritoneal dialysis into the abdominal cavity through a catheter and then discharging the used liquid for peritoneal dialysis from the body.

One form of peritoneal dialysis, Continuous Ambulatory Peritoneal Dialysis (CAPD), is typically performed by continuously contacting the peritoneal membrane with a dialysis fluid throughout the day. To enable CAPD, the patient manually removes used dialysate and manually infuses new dialysate, during which gravity is typically relied upon to move fluid into and out of the abdominal cavity.

Maintaining the sanitation of peritoneal dialysis becomes a priority during prolonged peritoneal dialysis. However, existing peritoneal dialysis devices are less safe and inconvenient to use, and may be costly, making it difficult for the patient to perform peritoneal dialysis on their own.

Detailed Description

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, like reference numerals generally refer to like parts throughout the various views unless the context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not intended to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter of the present application. It will be understood that aspects of the present disclosure, as generally described in the present disclosure and illustrated in the figures herein, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which form part of the present disclosure.

Fig. 1 shows a peritoneal dialysis set 100 according to one embodiment of the present application. In practice, the peritoneal dialysis set 100 can assist a patient in performing peritoneal dialysis procedures, particularly continuous ambulatory peritoneal dialysis procedures.

As shown in fig. 1, the peritoneal dialysis set 100 includes an ultraviolet sterilization module 110. The ultraviolet sterilization module 110 is configured to emit ultraviolet light toward an infusion connector assembly for performing peritoneal dialysis on a patient to sterilize at least a portion of the infusion connector assembly. In some embodiments, the wavelength of the ultraviolet light that can be used can be 200-400 nm. In some embodiments, ultraviolet light with wavelengths of 240-270nm is preferred.

In the embodiment shown in fig. 1, the infusion connector assembly includes a patient tip 122 and a patient connection tip 124. Where the patient tip 122 is one end of a catheter 126 extending from the patient, the patient tip 122 is typically attached to the patient; and a patient connection tip 124 for connecting the patient tip 122, the patient connection tip 124 being connected to a first container (not shown) of the peritoneal dialysis bag via a first tube and to a second container (not shown) of the peritoneal dialysis bag via a second tube, whereby the patient connection tip 124 can connect the patient tip 122 to either the first container or the second container. Wherein the first container is used for receiving new dialysis fluid to be fed in and the second container is used for collecting used dialysis fluid drained from the patient.

In some embodiments, the uv sterilization module 110 has a sterilization chamber 112. The sterilization chamber 112 is operable to house at least a portion of an infusion connector assembly, for example, the sterilization chamber 112 may house the patient tip 122 or both the patient tip 122 and the patient connection tip 124 when a peritoneal dialysis procedure is desired. The uv sterilization module 110 also includes a uv light source 114, the uv light source 114 for emitting uv light to the sterilization chamber 112. In some embodiments, the ultraviolet light source 114 is disposed within the sterilization chamber 112, as shown in fig. 1, for example on an interior wall of one or more sides of the sterilization chamber 112. The sterilization chamber 112 may be configured as a cylinder and, correspondingly, the uv light source 114 may be configured as a ring-like structure that extends annularly along the inner wall of the cylindrical sterilization chamber 112. In other embodiments, the ultraviolet light source may also be disposed outside the sterilization chamber. For example, the ultraviolet light source may be disposed at a distance from the sterilization chamber, and the sterilization chamber may have a fenestration or an ultraviolet-transparent window such that ultraviolet light can be incident into the sterilization chamber through the fenestration or window.

In the embodiment shown in fig. 1, the sterilization chamber 112 is defined by three portions, wherein a middle portion 112a is used for fixing the ultraviolet light source 114 and a first rotation shaft 116a and a second rotation shaft 116b are respectively provided at both ends thereof. In some embodiments, the middle portion 112a may also incorporate a power source 118 to power the ultraviolet light source 114. The other two portions of the sterilization chamber 112, i.e., the first rotating portion 112b and the second rotating portion 112c, are coupled to both ends of the middle portion 112a by rotating shafts 116a and 116b, respectively. The first rotating portion 112b has a sleeve-like structure, and the patient head 122 can be fixed to the first rotating portion 112b through the first rotating portion 112 b; and the second rotating portion 112c has a similar sleeve-like structure, the patient connection tip 124 can be secured to the second rotating portion 112c by passing through the second rotating portion 112 c. The first and second rotating portions 112b and 112c may rotate about the first and second rotating shafts 116a and 116b, respectively, to move between the open and closed positions. In the open position, the patient head 122 and the patient connection head 124 are separated from each other, as shown in fig. 1; when it is necessary to switch to the closed position, the first rotating portion 112b rotates in the clockwise direction shown in fig. 1, and the second rotating portion 112c rotates in the counterclockwise direction shown in fig. 1. After the first rotating part 112b and the second rotating part 112c rotate by a certain angle, the first rotating part 112b and the second rotating part 112c respectively drive the patient head 122 and the patient connecting head 124 fixed thereon to move into the sterilization chamber 112, so as to move the patient head 122 to an area capable of receiving the irradiation of the ultraviolet light source 114, or move the patient head 122 and the patient connecting head 124 to an area capable of receiving the irradiation of the ultraviolet light source 114 at the same time. In this manner, ultraviolet light emitted by the ultraviolet light source 114 can impinge upon the surface of the patient tip 122 and/or the patient connection tip 124 to sterilize them. In general, peritoneal dialysis bags containing a patient connection tip are typically disposable consumables, and thus do not typically require sterilization; the patient tip 122 is typically attached to the patient and needs to be reused, thus typically requiring sterilization of the patient tip 122.

In some embodiments, the uv light source 124 may be a uv emitting device, such as a Light Emitting Diode (LED), and as other embodiments, the uv light source may include one or more, such as two or more, uv emitting devices. The plurality of ultraviolet light emitting devices may be configured to emit ultraviolet light from different directions toward the infusion connector assembly to sterilize the infusion connector assembly. In the embodiment shown in FIG. 1, the ultraviolet light source 114 is provided as an annular structure having a center generally aligned with the axis of the patient tip 122 and a diameter greater than the diameter of the patient tip 122, thereby allowing emitted ultraviolet light to cover various locations on the outer surface of the patient tip 122.

In some embodiments, the uv sterilization module 110 may also include a uv switch (not shown) for controlling the uv emission of the uv light source 114. For example, a button may be provided on the intermediate portion 112a that the patient or other peritoneal dialysis operator can press to control the emission of ultraviolet light, or to cancel the emission. In some embodiments, the ultraviolet switch may also be activated by the rotation of the first rotating portion 112b and/or the second rotating portion 112c, thereby controlling the emission of ultraviolet rays. For example, after the first rotating portion 112b is rotated to its corresponding closed position, the ultraviolet switch may be activated (e.g., pressed) by the first rotating portion 112b, thereby causing ultraviolet light to be emitted; or further, after the second rotating portion 112c is rotated to its corresponding closed position, the ultraviolet switch may also be activated by the second rotating portion 112c, so that the emission of the ultraviolet rays is cancelled. Thus, the patient may connect the patient head 122 and the patient connection head 124 in an order of operation: first, the first rotating unit 112b where the patient head 122 is located is rotated to perform a sterilization process on the patient head 122; after a period of sterilization, such as 5 seconds, the second rotating portion 112c, where the patient connecting tip 124 is located, may be rotated to connect the patient tip 122 and the patient connecting tip 124 together. At this point, the patient can begin the fluid delivery process of peritoneal dialysis and simultaneously cancel the ultraviolet sterilization process.

It can be seen that the peritoneal dialysis set 100 shown in FIG. 1 sterilizes the infusion connector set by ultraviolet light. The device is easy to operate, convenient for patients to use, low in manufacturing and using cost, and excellent in sterilization efficiency, and effectively improves the safety of peritoneal dialysis operation.

Fig. 2A and 2B illustrate a peritoneal dialysis set 200 according to another embodiment of the present application. Wherein fig. 2A is an external view of the peritoneal dialysis set 200 and fig. 2B is an internal view of the peritoneal dialysis set 200.

As shown in fig. 2A and 2B, the peritoneal dialysis set 200 includes an ultraviolet sterilization module 210. The uv sterilization module 210 is shown as an elongated box having a cover 212a and a bottom housing 212b that mates with the cover 212 a. The cover 212a and the bottom housing 212b together define a cavity for receiving an infusion connector assembly. Cover 212a may be moved relative to bottom housing 212b, e.g., removed from bottom housing 212b, or rotated relative to bottom housing 212b, thereby exposing a cavity therein to allow an infusion connector assembly to be placed therein. One or more uv light sources 214 may be housed in the cavity of the elongated box so that the cavity may be used as a sterilization chamber. For example, one or more uv light sources may be disposed on the inner wall of the bottom housing 212b, one or more uv light sources may be disposed on the inner wall of the cover 212a, or multiple uv light sources may be disposed on both the inner walls of the bottom housing 212b and the cover 212 a. In addition, the uv sterilization module 210 has a switch 216, which is disposed on the cover 212 a. The switch 216 may be used to control the opening and closing of the cover 212 a.

The first end of the uv sterilization module 210 has an opening 218a that allows passage of a catheter 232 attached to the patient's body, thereby securing the patient's tip within the sterilization chamber. The second end of the uv sterilization module 210 also has two openings 218b and 218 c. In some embodiments, the second end is opposite the first end, and the two openings 218b and 218c on the second end allow the first tubing 234 and the second tubing 236 of the peritoneal dialysis bag to pass through, respectively. In this way, the patient connection tip of the peritoneal dialysis bag can also be secured within the sterilization chamber and fixedly connected to the patient tip. In some embodiments, the openings 218a, 218b, and 218c of the first and second sides may be combined by half openings on the side of the bottom housing 212b and half openings on the side of the cover 212A, as shown in FIG. 2A. This design facilitates installation of the patient head and patient connection head into the sterilization chamber. In addition, an infusion switch 219 may be disposed between the bottom housing 212b and the cover 212a, and may be moved to control the on and off of the first conduit 234 and the second conduit 236.

In practice, the patient end of the connecting catheter and the patient connecting end of the connecting first and second conduits 234, 236 may be placed within the sterilization chamber by opening the cover 212 a. The conduit 232 passes through the opening 218a at the first end of the uv sterilization module 210, and the first conduit 234 and the second conduit 236 pass through the two openings 218b and 218c at the second end, respectively, and then the cover 212a is closed with the bottom housing 212 b. In some embodiments, after the cover 212 is opened and the patient tip is placed within the sterilization chamber, the ultraviolet light source 214 may begin emitting ultraviolet light for a period of time to sterilize the patient tip and the patient connection tip within the chamber. In some embodiments, a separate UV light source switch (not shown) may also be provided to control the emission of UV light. After the sterilization process is completed, the second tube 236 can be turned on by switching the infusion switch 219, and the used dialysate in the patient can be drained via the catheter, the patient tip, the patient connection tip, and the second tube 236, and then be introduced into a second container connected to the second tube and stored therein. When the used dialysate is drained from the patient's peritoneal cavity, the infusion switch 219 can be toggled to turn the first tubing 234 on and the second tubing 236 off. In this way, new dialysate can be fed from the first container into the patient's peritoneal cavity via the first tubing 234, the patient connection tip, the patient tip, and the catheter. In this way, the patient can complete the complete peritoneal dialysis procedure very conveniently and safely. In some embodiments, the infusion switch 219 may also be moved in the direction of the opening 218a, thereby placing the first and second conduits 234, 236 in communication with one another. Thus, the patient can drain the dialysate and a small amount of air or air bubbles in the first tubing 234 into the second tubing 236 and then switch to connect the first tubing 234 to the catheter for infusion.

As can be seen from the embodiment shown in FIG. 1 and FIGS. 2A and 2B, by providing a UV sterilization module on the peritoneal dialysis set for securing an infusion connector assembly, a patient or other peritoneal dialysis operator can sterilize the infusion connector assembly (and particularly the patient's head) before or during a peritoneal dialysis procedure. This can effectively improve the cleanliness of the infusion connector assembly, thereby avoiding or at least reducing infection of the patient's peritoneal cavity due to peritoneal dialysis. In addition, the peritoneal dialysis device has compact structure, convenient use and low production cost, and is particularly suitable for patients to use at home or other places.

Fig. 3 shows a peritoneal dialysis set 300 according to another embodiment of the present application.

As shown in fig. 3, the peritoneal dialysis set 300 includes an ultraviolet sterilization module 310, the ultraviolet sterilization module 310 configured to emit ultraviolet light toward an infusion connector assembly for performing peritoneal dialysis on a patient to sterilize the infusion connector assembly. In particular, the uv sterilization module 310 may sterilize the patient tip (not shown) of the infusion connector assembly.

In some embodiments, the uv sterilization module 310 is a cylindrical structure having a cavity therein, which serves as a sterilization chamber 312 of the uv sterilization module. One end of the sterilization chamber 312 has an opening that allows the patient's head to pass therethrough into the sterilization chamber 312. An annular uv light source (not shown) is disposed within the chamber 312 and the patient's tip can be irradiated by uv light emitted from the annular uv light source. The opening of the sterilization chamber 312 is defined by a cylinder 312a, and may be opened or closed by a fixing ring 312b attached to the cylinder 312 a. When the patient tip is placed in the sterilization chamber 312, the securing ring 312b may be depressed to secure the patient tip. At this point, the cylinder 312a and the retaining ring 312b still have a passageway therebetween that allows the conduit 332 to pass therethrough, extending from the interior of the sterilization chamber 312 to the exterior of the chamber. The ultraviolet sterilization module 310 may also include a cover 312c coupled to the cylinder 312a and defining a sterilization chamber 312 with the cylinder 312 a. In some embodiments, the cover 312c may be constructed of a transparent or translucent material. In some embodiments, the transparent or translucent material is a uv-opaque material, for example, that filters uv light to prevent uv light from passing through the sterilization chamber 312 and out of the chamber.

In the embodiment shown in fig. 3, the peritoneal dialysis set 300 also has a connection module 320, similar in internal structure to the embodiment shown in fig. 2A and 2B, for securing a patient connection tip and corresponding two tubes. In addition, the connection module 320 has a groove 315 at one end thereof for receiving and fixing the ultraviolet sterilization module 310. In this manner, the uv sterilization module 310 and the connection module 320 may be connected to each other such that the patient end and the patient connection end are secured together to facilitate the peritoneal dialysis procedure. In addition, two infusion switches 321 may be disposed on the connection module 320, and are disposed on two sides of the connection module 320 to control the on and off of the first pipe 322 and the second pipe 323.

It should be noted that in some embodiments, the peritoneal dialysis set 300 can also include no connection module 320, but only the uv sterilization module 310.

It can be seen that the patient can pre-sterilize the patient's head prior to performing the peritoneal dialysis procedure using the uv sterilization module 310 of fig. 3, and then connect the patient's head to the patient's connection head of the peritoneal dialysis bag to perform the peritoneal dialysis procedure. The peritoneal dialysis device is compact in structure and convenient to use, and can effectively improve the cleanliness of the end of a patient, so that the infection of the abdominal cavity of the patient caused by peritoneal dialysis is avoided or at least reduced. Thus, the peritoneal dialysis set-up is particularly suited for use by patients at home or other locations remote from the hospital.

Fig. 1 to 3 show various peritoneal dialysis apparatuses capable of sterilizing an infusion connector set for peritoneal dialysis. In some embodiments, the peritoneal dialysis set can also include other components to better assist the patient or other operator in performing the peritoneal dialysis procedure, and these embodiments are further described below.

Fig. 4 shows a peritoneal dialysis set 400 according to another embodiment of the present application.

As shown in fig. 4, the peritoneal dialysis set 400 includes a rack 410, and a first support module 420, a second support module 430, an ultraviolet sterilization module 440, a control module (not labeled) and a control panel 460 disposed on the rack 410.

In particular, the frame 410 provides support for some modules or components of the peritoneal dialysis set 400. In some embodiments, the stent 410 is substantially elongate in shape. In some embodiments, the stand 410 may be telescoping along its length so that it may be stowed to conserve storage space. In some embodiments, a first support module 420 may be mounted at a top region of the rack 410, such as removably or non-removably mounting the first support module 420. The first support module 420 is used to support a first container 421 containing a first liquid, for example a first container 421 containing new dialysis liquid. In some embodiments, the first container 421 may be a solution bag or a solution bottle for storing unused dialysate. The first support module 420 may include a hook or support arm extending from the support 410 at or near the top of the support 410; while the solution bag or bottle usually has a hanging hole through which a hook or a support arm can hang the solution bag or bottle at a predetermined height, for example, a position higher than the abdominal cavity of the patient. In this way, the dialysis fluid can flow from the first reservoir 421 into the abdominal cavity of the patient by means of gravity. In other embodiments, the first support module 420 may be a gripper device disposed near the top of the rack that can grip the first container 421.

In some embodiments, a second support module 430 is mounted at a bottom region of the stand 410, the second support module 430 for supporting a second container 431. The second container 431 is used to collect a second fluid, such as used dialysate, that is drawn from the patient. The second support module 430 may be removably or non-removably mounted to the bottom of the rack 410. In some embodiments, the second support module 430 may be a disk-shaped support platform; in other embodiments, the second support module 430 may be a bucket-shaped support table, as shown in FIG. 4, or other suitable support structure. The second support module 430 is typically disposed at a lower elevation, e.g., below the patient's abdominal cavity, to enable the used dialysate to flow from the patient's abdominal cavity into the second container 431 by gravity. In some embodiments, the second support module 430 comprises a weigher 432 for weighing the second container 431 (containing the second liquid collected therein) and generating weighing data indicative of the weighing of the second container 431. In practice, the second container 431 may be a drain bag, and the scale 432 may measure the weight of the used dialysate flowing into the drain bag and generate weighing data based on the weight of the liquid flowing into the drain bag. In some embodiments, the scale 432 may have wireless data communication capabilities such that weighing data may be transmitted from the scale 432, for example, to an external data processor or processing device, or to a control module or data processor internal to the peritoneal dialysis set 400 for subsequent data processing or control of a dialysis operation.

Still referring to fig. 4, the peritoneal dialysis set 400 is used to facilitate the connection of an infusion connector assembly 411, the infusion connector assembly 411 operatively securing or controlling the fluid connection between the first container 421, the second container 431 and the patient's peritoneal cavity. Specifically, the infusion connector assembly 411 includes a patient connection tip 412 and a patient tip 413. Wherein the end of the catheter 414 extending from the patient is a patient end 413, the patient end 413 being removably connected to the patient connection end 412. For example, the patient tip 413 may be coupled to the patient connection tip 412 by a threaded or snap-fit connection. The patient connection tip 412 is typically a three-way fitting in which a first end of the patient connection tip 412 is fluidly coupled to a first container 421 via a first conduit 422, a second end of the patient connection tip 412 is fluidly coupled to a second container 431 via a second conduit 434, and a third end of the patient connection tip 412 is connected to the patient tip 413. In this way, fresh dialysate in the first container 421 can flow along the first tubing 422 to the infusion connector assembly 411 and into the patient via the infusion connector assembly 411 and the catheter 414. In addition, used dialysate within the abdominal cavity of the patient may flow through the conduit 414 to the infusion connector assembly 411 and further through the infusion connector assembly 411 and the second tubing 434 into the second container 431. In this way, the weigher 432 can measure the weight of the liquid flowing into the second container 431. For example, the scale 432 may measure the initial weight of the second container 431 and then measure the instantaneous weight of the second container 431 during the dialysis process, and the difference between the two weights is the weight of the liquid flowing into the second container 431.

In some embodiments, the turning on and off of the first conduit 422 and the second conduit 434 may be controlled by respective conduit switches. The pipeline switch includes, for example, a first valve and a second valve, wherein the first valve controls the conduction and closing of the first pipeline 422 and the second valve controls the conduction and closing of the second pipeline 434. It is also noted that in some embodiments, the first and second valves may also control the flow rate of the fluid flowing in conduits 422 and 434, thereby determining whether an increase or decrease in flow rate is desired based on the physical condition of the patient or other factors. In some embodiments, the first valve and the second valve may be attached to an infusion connector assembly. In some embodiments, two clips may be provided to clip the first conduit 422 and the second conduit 434, respectively.

As mentioned above, the fresh dialysate (first liquid) in the first container 421 is typically gravity fed into the patient, while the used dialysate (second liquid) is also typically gravity fed into the second container 431. Alternatively, in some other embodiments, the flow of dialysate may also be controlled by means of an active fluid control device. For example, the peritoneal dialysis set 400 can also include a fluid pump configured to pump a first liquid from the first container 421 into the peritoneal cavity, and/or pump a second liquid into the second container 431. Wherein, when the first liquid needs to be pumped from the first container 421, the first pipe 422 is conducted, and the second pipe 434 is closed; when it is desired to pump a second liquid into the second container 431, the second conduit 434 is turned on, and the first conduit 422 is turned off. In some embodiments, the fluid pump is an air pump.

In some embodiments, the peritoneal dialysis set 400 further includes a control module (not shown) communicatively coupled to the scale 432 that is configured to receive the weighing data from the scale 432 and generate treatment data based on the weighing data. The weighing data comprises the result of weighing the second container (including the used dialysate collected therein). In some embodiments, the weighing result of the second container may be a real-time weight of the second container during dialysis, i.e. the weighing of the second container is performed continuously as dialysis proceeds, and data is generated for respective time points. In some embodiments, the weighing result of the second container may also be the weight of the second container at the end of the dialysis. In other embodiments, the weighing data may also include a change in the weighing of the second container over time, such as a statistic or record of the weight of the second container and its change every 1 second, 2 seconds, 5 seconds, or longer. In addition, the control module may also acquire other treatment data related to peritoneal dialysis, or generate treatment data based on weighing data and other related data. For example, the treatment data may include dialysate exchange time, number of exchanges, ultrafiltration rate (ultrafiltration rate), dialysate flow rate, and/or the like. Wherein the exchange time and/or the number of exchanges can be determined on the basis of patient or operator input, the ultrafiltration rate can be determined on the basis of the weighing data and the weight of the fresh dialysis fluid contained in the first container, and the dialysis fluid flow rate (in particular the flow rate of the used dialysis fluid) can be calculated on the basis of the weighing data and the exchange time. In some embodiments, the fluid pump may also be communicatively coupled to the control module for receiving a pumping signal instructing it to pump the first liquid or the second liquid. In some embodiments, the pump signal is generated based on one or more of fluid exchange time, number of exchanges, ultrafiltration rate, and/or dialysate flow rate. For example, upon determining that the flow rate of used dialysate is too low (substantially zero, e.g., less than 1 ml/min) for a period of time, the control module may generate a pump signal to indicate that pumping of used dialysate into the second container is to be stopped.

In some embodiments, the control module may be communicatively coupled to an external processor (not shown) to send the weighing data and/or the treatment data to the external processor. In some embodiments, the control module may obtain a patient identification associated with the patient and send the patient identification to the external processor along with the weighing data and/or the therapy data. In some embodiments, the patient or operator performing the peritoneal dialysis procedure can manually enter a patient identification, such as a serial number in a numeric format, via a key, touch screen, or other similar input device; alternatively, the control module may be coupled to an electronic identification card reader (RFID reader) and the reader may read the patient identification stored in an identification card carried by the patient; alternatively still, the control module may be coupled to a barcode scanner and the barcode scanner reads an identification barcode carried by the patient identifying the patient's identity. In some embodiments, the control module may send the weighing data, treatment data, and other data to the external processor via wired or wireless transmission such as Wi-Fi, bluetooth, infrared, NFC, wireless communication network, and the like. In some embodiments, the external processor may be a computer, a server, a cell phone, a tablet computer, or the like.

In some embodiments, the input module may also be used to receive user input related to the patient's health condition, such as the patient's heart rate, pulse, blood pressure, height, weight, age, or other information. The control module may receive these user inputs and determine appropriate treatment data based on these user inputs. For example, the control module may select a maximum allowable dialysate exchange time, a dialysate exchange amount, etc. therapy data based on the user's blood pressure, weight, or age. These treatment data may assist the patient in performing peritoneal dialysis procedures. For example, after the time of the dialysis operation exceeds the maximum allowable dialysate exchange time, the control module can issue a control command instructing the peritoneal dialysis operation to be stopped.

The weighing data detected by the scale helps the patient or other operator to monitor the progress of the treatment during the transfer of used dialysate from the patient's peritoneal cavity to the second container. In some embodiments, the control module may periodically retrieve the weighing data from the scale to update the weighing data on-the-fly. In other embodiments, the used dialysate transfer process may be considered to have ended when the acquired weighing data has not changed within a predetermined period of time. Accordingly, the control module may generate an alarm signal to indicate the end of the used dialysate transfer. The predetermined period of time may be set according to the experience of the operator or the patient, for example, to 1 minute, 2 minutes, 3 minutes, or more. The alarm signal may be sent to the external processor through the control module and an alarm may be issued by a prompting device controlled by the external processor, such as a display screen displaying an alarm image or text, or a speaker playing an alarm sound or audio. In this way, the patient or other operator can be prompted to check the peritoneal dialysis set and end the peritoneal dialysis procedure.

In some embodiments, the control panel 460 of the peritoneal dialysis set 400 is mounted in the middle region of the rack 410. The control panel 460 is a generally box-like structure that includes a back side and an operating side, with the back side being opposite the operating side. The back surface of the control panel 460 is provided with a snap-fit portion that is snap-fitted in the middle region of the bracket 410 so that the control panel 460 can be fixed on the bracket 410. One side of the control panel 460 has a groove 461, the groove 461 having a size corresponding to the first duct 422 as a first passage to receive and fix a portion of the first duct 422. The control panel 460 further includes a support surface 463 extending downward along the back surface of the control panel 460, and a receiving surface 464 extending from the bottom of the support surface 463 toward the operating surface. The receiving surface 464 has an opening 462 at a side corresponding to the groove 461 for serving as a second channel for securing a portion of the second conduit 434. In some embodiments, the control panel 460 is also provided with a separation column 465 in the chamber, which separation column 465 may separate the first conduit 422 and the second conduit 434. In addition, the control panel 460 further includes a flow switch assembly (not shown) disposed in the first and second passages 461, 462, which is capable of controlling the on and off of the first and/or second conduits 422, 434, thereby controlling the flow of dialysate. In some embodiments, the flow switch assembly can also control the flow rate of the liquid within the first conduit 422 and/or the second conduit 434. It will be appreciated that in some embodiments, the flow control assembly may also not be disposed within the channel of the control panel 460, but rather attached to the first and second conduits 422, 434 as separate components. For example, the flow switch assembly may be a separately provided valve or clip.

Still referring to fig. 4, the peritoneal dialysis set 400 also includes an ultraviolet sterilization module configured to emit ultraviolet light toward the infusion connector assembly 411 for peritoneal dialysis of the patient to sterilize the infusion connector assembly 411. In some embodiments, the ultraviolet sterilization module may be disposed in the control panel 460. Specifically, the support surface 463, the receiving surface 464, and the bottom surface of the control panel form a chamber in which the infusion connector assembly 411 is received. An ultraviolet light source 440 of an ultraviolet sterilization module is provided inside the receiving surface 464. The ultraviolet light source 440 can emit ultraviolet light toward the infusion connector assembly 411. It will be appreciated that the ultraviolet light source 440 may also be disposed at other locations, such as inside the support surface 463.

In some embodiments, the control panel 460 may also include a baffle (not shown) that at least partially covers the chamber housing the infusion connector assembly 411 to isolate or reduce contamination of the infusion connector assembly 411 from the outside environment. One side of the flap is pivotally connected to the control panel 460 to allow the chamber to be opened or closed.

In some embodiments, the control panel 460 also includes a display 466 for displaying various peritoneal dialysis operation related information. The control panel 460 also has input buttons and/or control buttons 467 to input information and/or perform control operations. In some embodiments, the display 466 can display the exchange time, number of exchanges, ultrafiltration rate, or flow rate. Based on the information displayed by display 466, the patient or other peritoneal dialysis operator can control the progress of the peritoneal dialysis procedure, such as controlling the flow rate, by entering buttons and/or control buttons 467.

In some embodiments, the control panel 460 may also include a control module (not shown) that is built into the case of the control panel, for example. Peritoneal dialysis set 400 can also include a memory for storing information and data needed for the peritoneal dialysis procedure. It will be appreciated that in some other embodiments, the control module and/or memory may also be provided external to the control panel 460, for example, the control module may be designed in a configuration similar to a mobile data processing terminal for ease of use by a patient or operator.

In some embodiments, peritoneal dialysis set 400 further comprises a heater (not shown) for heating first container 421. The heater may be designed to slowly heat the first container 421 and the first liquid therein to a temperature of the human body temperature. The heater may be provided at the first support module 420 or the second support module 430, or at other suitable locations. In some embodiments, a heater is disposed on the first supporting module 420, which can instantly heat and keep warm the first container 421, so as to avoid the temperature of the dialysate of the first container 421 from being too low. As other embodiments, the heater may also be disposed at the second support module 430. The first container 421 may be placed on the second support module 430 for preheating before the dialysis operation and placed on the first support module 420 after reaching the body temperature for subsequent dialysate exchange.

In some embodiments, the control panel 460 may also have one or more operational indicators thereon, such as indicator lights with indicia, or different operational indication areas on the display 466) for indicating different operations of the peritoneal dialysis. For example, the operation indicator may be an icon displayed by the liquid crystal display 466, such as a heating icon, a flow rate icon, a discharge icon, and the like. For example, the operator may click on the heating icon, thereby controlling the heater to heat the first container 421 to a temperature of about the body temperature; the operator can click the flow icon to control the flow switch assembly to close the second tube and open the first tube, so that the dialysate begins to flow into the patient; the operator can click on the drain icon and control the flow switch assembly to open the second conduit and close the first conduit so that the used dialysate is collected in the second container. It will be appreciated that the above-described operation indicators are merely exemplary and that various modifications and substitutions may be made by those skilled in the art depending on the actual needs.

In some embodiments, the peritoneal dialysis set 400 can also include a printing module (not shown) for printing weighing data and/or health data associated with the patient's health condition. These data may be printed as text, or in a barcode form, such as a two-dimensional code (QR code). The patient can carry the printed text or bar code to a doctor who can read the text or scan the bar code with a bar code scanner to understand and track the patient's treatment. In other embodiments, the weighing data and/or health data may also be sent to the patient's personal data terminal, such as a cell phone, in the form of electronic data, and the data may be displayed by the personal data terminal as text or bar code. Similarly, the patient may carry his personal data terminal to the doctor and provide it to the doctor.

Fig. 5A and 5B illustrate a peritoneal dialysis set 500 according to another embodiment of the present application. Fig. 5A is a perspective view of the peritoneal dialysis set 500, and fig. 5B is a top view of the control panel of the peritoneal dialysis set 500.

As shown in fig. 5A and 5B, the peritoneal dialysis set 500 includes a support assembly 510, a connection assembly 520, and an ultraviolet sterilization module 530. The connection assembly 520 is used to assist in connection of the infusion connector assembly, and the ultraviolet sterilization module 530 is used to sterilize the infusion connector assembly.

Specifically, support assembly 510 includes a base 511 and a support 512 extending upwardly from base 511. A first support module 513 is attached to the top end of the rack 512 for supporting a first container of the peritoneal dialysis bag; and a second support module 514 is positioned on the base 511 for supporting a second container of the peritoneal dialysis bag. For the specific structures of the base 511, the bracket 512, the first supporting module 513 and the second supporting module 514, please refer to the related description of the previous embodiments, which is not repeated herein.

The support assembly 510 also includes a control panel 515 attached to a central region of the bracket 512. The connection assembly 520 and the uv sterilization module 530 may be integrated on the control panel 515.

Specifically, referring to fig. 5B, the uv sterilization module 530 includes a sterilization chamber 531 configured as a recess in the control panel 515 in which a uv light source (not shown) is disposed, such as on a sidewall of the recess. On one side of the recess is a through hole 532, and a catheter extending from the abdominal cavity of the patient can be received in the through hole 532. Thus, when the patient end of the catheter is received in the sterilization chamber 531, the ultraviolet light emitted by the ultraviolet light source can be directed onto the patient end to sterilize the patient end. In some embodiments, the recess may also be covered by a baffle (not shown) to substantially close the sterilization chamber 531 to prevent dust or other contaminants from contaminating the patient's head.

Also integrated on the control panel 515 is a connection assembly 520 comprising a first channel 521, a second channel 522 and a third channel 523. One ends of the first channel 521, the second channel 522 and the third channel 523 are joined together and arranged in a general Y shape. In carrying out fluid delivery for peritoneal dialysis procedures, first channel 521 receives a first tubing, second channel 522 receives a second tubing, and third channel 523 receives a patient connection tip and a patient tip, i.e., an infusion connector assembly. In addition, at least some areas of the channels 521, 522, and 523 are covered with a barrier 524 that can cooperate with the channels to secure the tubing of the peritoneal dialysis bag and the infusion connector assembly from movement. In some embodiments, baffle 524 surface may be provided with one or more indicators for indicating the operation of peritoneal dialysis. For example, the surface of the baffle 524 is further provided with a knob 525, and the knob 525 can drive the baffle 524 to rotate relative to the channel, and make the channel be turned off or on. In this way, the baffle 524 can be used as a flow switch assembly, and by rotating the knob 525 and the baffle 524, the flow of fluid in the first pipe 521 and/or the second pipe 522 can be turned off or on to enable a patient or an operator to perform a corresponding infusion operation.

In the embodiment shown in fig. 5B, a display 516 is further disposed on the control panel 515 for displaying information such as the exchange time, the number of exchanges, the ultrafiltration rate or flow rate.

Further, the display 516 may also display weighing data and/or health data in the form of a two-dimensional code associated with the health condition of the patient.

In some embodiments, the peritoneal dialysis set 500 further includes one or more of a control module, a scale, a fluid pump, a heater, an output module, and a printing module, which are not described in detail herein, and the description of the control module, the scale, the fluid pump, the heater, the output module, and the printing module can be referred to the description of the previous embodiments.

Fig. 6 shows a peritoneal dialysis set 600 according to another embodiment of the present application.

As shown in fig. 6, the peritoneal dialysis set 600 includes a control panel 610, which control panel 610 has a connection assembly 620 and an ultraviolet sterilization module 630 integrated thereon. The control panel 610 has a support base 611, and the support base 611 may be generally "C" shaped or "[" shaped. When performing a peritoneal dialysis procedure, the patient can insert his legs into the support base 611 in order to secure the connection assembly 620 and the uv sterilization module 630 on the control panel 610. In this way, the patient may conveniently use the connection assembly 620 to assist in connection of the infusion connector assembly and the ultraviolet sterilization module 630 to sterilize the infusion connector assembly.

Specifically, a connection assembly 620 is disposed on one side of the control panel 610 and includes a first channel 621, a second channel 622, and a third channel 623, wherein the first channel 621 is configured to receive a first conduit, the second channel 622 is configured to receive a second conduit, and the third channel 623 is configured to receive a patient connection tip and a patient tip. One ends of the first passage 621, the second passage 622 and the third passage 623 are joined together, and the whole body is in a Y-shaped structure. At the inlets of the first and second passages 621 and 622 may be provided clamps 624 and 625, respectively, which may open or close the first and second passages 621 and 622, respectively, to control the flow of the liquid of the first and second pipes accommodated therein during the period.

An ultraviolet sterilization module 630 is disposed at the other side of the control panel 610, and the height of the ultraviolet sterilization module 630 is lower than that of the connection assembly 620. Specifically, the ultraviolet sterilization module 630 includes a sterilization chamber 631 and an ultraviolet light source 632 disposed within the sterilization chamber 631. The sterilization chamber 631 may be loaded into a patient head such that the ultraviolet light source 632 may emit ultraviolet light toward the patient head to sterilize the same. The sterilization chamber 631 and infusion connector assembly are described with reference to the previous embodiments and will not be described again. In some embodiments, the sterilization chamber 631 has a groove shape, and the top of each of the two sidewalls of the groove-shaped chamber 631 is provided with an ultraviolet light source 632 to emit ultraviolet light into the groove. The drive circuit of the uv light source is built in the support panel main body, and the switch 633 of the uv light source is provided on the control panel 610 outside the sterilization chamber 631.

Still referring to fig. 6, the peritoneal dialysis set 600 also includes a support assembly 640, separate from the control panel 610, that includes a support module 641 for receiving the first container and/or the second container. In addition, the bottom of the support module 641 may be provided with a heater (not shown in the drawings) and a scale (not shown in the drawings). Specifically, when a peritoneal dialysis operation is not being performed, a peritoneal dialysis bag including a first container and a second container can be received in support module 641; and when the peritoneal dialysis operation is to be performed, the heater can heat the first container to heat the dialysate therein to the body temperature of the human body. Thereafter, while the peritoneal dialysis procedure is being performed, the first container is suspended to a higher position (e.g., a height above the patient's peritoneal cavity) while leaving only the second container in support module 641. In this way, the weigher can weigh the second container at any time to determine the weight of the used dialysate collected therein.

The peritoneal dialysis set 600 can also include a control module (not shown) that can be integrated into the support assembly 640. The control module is configured to periodically acquire weighing data from the scale. In some embodiments, the control module may be communicatively coupled to an external processor to send weighing data and/or treatment data to the external processor.

The control module may also be coupled to an input module 642 provided on the support assembly 640 for receiving user input associated with the health condition of the patient, or other user input such as patient identification, or the like. In some embodiments, the input module may take the form of a button, including, for example, a timing button, a warm up button, a cool down button, a weigh down button, a print button, or an enter button. By pressing the relevant button, the patient can control the relevant operation. Also integrated on the support assembly 640 is a print module 644, which print module 644 prints data in the form of two-dimensional codes and/or text. In addition, a display 643 is provided on the support assembly 640 for displaying various data and information.

Fig. 7A shows a peritoneal dialysis set 700 according to one embodiment of the present application.

As shown in fig. 7A, the peritoneal dialysis set 700 includes a frame 710, and a first support module 720, a second support module 730, storage cases 740, 741, and 742, and an environmental sterilization module 750 disposed on the frame 710.

In particular, the support 710 provides support for some modules or components of the peritoneal dialysis set 700. In some embodiments, the cradle 710 is substantially elongate in shape. A first support module 720 may be mounted at a top region of the bracket 710, such as with or without the first support module 720 being removably mounted. The first support module 720 is used to support a first container of a peritoneal dialysis bag. In some embodiments, the first container may be a solution bag or a solution bottle for holding unused dialysate. The first support module 720 may include a hook or support arm extending from the support 710 that may suspend the first container above the abdominal cavity of the patient.

A second support module 730 is installed at a bottom region of the stand 710, and the second support module 730 is used to support a second container. The second container is used to collect a second fluid, i.e. used dialysis fluid, which is withdrawn from the patient. The second support module 730 may be a disk-shaped support platform that is generally positioned below the patient's abdominal cavity to enable the used dialysate to flow by gravity from the patient's abdominal cavity into the second container. In some embodiments, a scale may be included in the second support module 730 for weighing the second container (containing the second liquid collected therein) and generating weighing data indicative of the weighing of the second container. In some embodiments, the scale may have wireless data communication capabilities such that the scale data may be transmitted from the scale, for example, to an external data processor or processing device, or to a control module or data processor internal to the peritoneal dialysis set 700 for subsequent data processing or control of the dialysis operation.

Mounted in the middle of the frame 710 are storage cassettes 740, 741, and 742 for holding peritoneal dialysis bags or infusion supplies ready for use, as well as other components of the peritoneal dialysis set 700, such as connection assemblies and/or uv sterilization modules. In some embodiments, the magazine 740 may be integrated with a heater to enable heating of the first container. It will be appreciated that the heater may also be integrated in other modules or locations, for example in the reservoir cartridge 741. As to the structure and function of the connection assembly and the uv sterilization module, reference may be made to the description of the embodiment shown in fig. 1 to 3, which is not described herein again. The storage case 740 has a storage cavity and a cover, and an article can be put into or removed from the storage cavity by opening and closing the cover. In some embodiments, the connection between the cover and the storage compartment may be provided with a damping device so that the closing and opening of the cover may be cushioned to avoid damage to the storage compartment 740. It will be appreciated that the storage case 741 or 742 may also have a similar damping device.

Further, the peritoneal dialysis set 700 shown in fig. 7A has an environmental sterilization module 750 mounted on the frame 710. The environmental sterilization module 750 is disposed at a top region of the rack 710 and proximate to the first support module 720. The environmental sterilization module 750 can emit ultraviolet rays to the environment (which is typically a closed or semi-closed space) in which the peritoneal dialysis set 700 is located, thereby sterilizing the environmental space with ultraviolet rays. In the embodiment shown in fig. 7A, the environmental sterilization module 750 includes an ultraviolet light source 751 and an isolation enclosure 752. The ultraviolet light source 751 is generally long tube-shaped, and extends for a length along the vertical direction, for example, 10 cm to 50 cm. The cage 752 includes a plurality of spacers around the outside of the ultraviolet light source 751 that prevent a patient or other person from touching the ultraviolet light source 751, and also allows ultraviolet light to be emitted from the ultraviolet light source 751. In some embodiments, the ultraviolet light source 751 may be an ultraviolet light emitting diode, while in other embodiments, the ultraviolet light source 751 may also be an ultraviolet fluorescent lamp.

Due to the sterilization effect of the environment sterilization module 750 on the environment space, when the patient uses the peritoneal dialysis device 700 for peritoneal dialysis, the number of microbial pathogens in the environment is greatly reduced, so that the risk of infection in the peritoneal cavity of the patient is reduced, and the safety of the peritoneal dialysis operation is improved.

In some embodiments, the peritoneal dialysis set 700 can also have a control module (not shown) that can be coupled to the environmental sterilization module 750 and used to control the environmental sterilization module 750 on and off. For example, the control module may receive control commands entered by a patient or other operator and turn the environmental sterilization module 750 on or off according to the control commands. For example, the patient may turn on the environmental sterilization module 750 to sterilize the environmental space prior to performing the peritoneal dialysis procedure; after a period of time (e.g., 30 minutes), the patient may turn off the environmental sterilization module 750 and then connect the infusion connector assembly for the peritoneal dialysis procedure. In some embodiments, the control module of the peritoneal dialysis set 700 can be coupled to an external control device, such as a patient's personal data terminal, and receive control commands entered by the patient through the external control device; based on the received control commands, the control module may control the environmental sterilization module 750 to turn on and off. In other embodiments, the control module may generate the control command according to other triggering conditions, for example, the control module may periodically turn on or off the environmental sterilization module 750 according to preset time conditions, for example, 9 pm turn on and 9 half turn off every day. In addition, the peritoneal dialysis set 700 can also have a sensing module, such as an infrared sensor, that can sense the approach of a patient or other person thereto, i.e., detect the presence of a person within the environmental space. Further, the control module may be coupled to the sensing module and receive a detection result of the sensing module. When the sensing module senses that the patient or other people are close to the environment, the control module can send a control command to instruct the environment sterilization module 750 to be turned off, so that the ultraviolet rays are prevented from damaging the people. In some embodiments, the sensing module, such as an infrared sensor, may be disposed on the support 710.

Fig. 7B shows one arrangement of an infrared sensor for detecting the presence of a person. As shown in fig. 7B, 4 infrared sensors 770 (one of which is hidden from view by the support 710) are mounted at four locations spaced apart from each other above the support 710 so as to point at one location of the support 710. In this way, the infrared sensor can achieve substantially full 360 degree coverage, thereby detecting a person approaching the peritoneal dialysis set from all directions. In this way, no matter from which orientation the patient or doctor is approaching, the infrared sensor 702 can detect, so that the control module can control the environmental sterilization module to switch off accordingly, and avoid injury to personnel due to ultraviolet radiation.

It will be appreciated that in some other embodiments, the environmental sterilization module can also be located elsewhere on the peritoneal dialysis device. For example, the environmental sterilization module may be disposed in a middle portion of the rack, extending in a vertical direction, while the first support module is disposed in an upper portion of the rack. For another example, the environmental sterilization module may be disposed at an upper portion of the stand and extend in a substantially horizontal direction, and may include an ultraviolet light source and an outer frame for fixing the ultraviolet light source, wherein the outer frame surrounds only an end portion of the ultraviolet light source, thereby enabling the ultraviolet light source to emit ultraviolet rays substantially upward and downward. For another example, the environmental sterilization module can be arranged in the middle of the bracket near the storage box; it may include a semi-closed housing constructed in a U-shape, both end portions of which are installed at both sides of the middle portion of the bracket, and an ultraviolet light source which is snap-fitted into the semi-closed housing, and the middle portion of which is installed at a fixing protrusion extending from the middle portion of the bracket.

Those skilled in the art will appreciate that the different modules of the different embodiments of the present application can be combined with or substituted for each other as desired for a particular application. For example, the peritoneal dialysis set 700 shown in fig. 7A can also include the uv sterilization module shown in the embodiment of fig. 1-6, or other components, such as heaters, control panels, displays, active fluid control devices, and the like. Those skilled in the art will appreciate that the environmental sterilization module 750 of the peritoneal dialysis set 700 shown in fig. 7A can also be integrated into embodiments such as those shown in fig. 4-6.

Fig. 8 shows a schematic partial structure of a peritoneal dialysis set according to one embodiment of the present application. Wherein the partial structure is located in a lower region of the peritoneal dialysis set. The structure and components of the upper region of the peritoneal dialysis set can be substantially the same as the corresponding structure and components of peritoneal dialysis set 700 shown in FIG. 7A, and thus are not shown in FIG. 8.

As shown in fig. 8, the peritoneal dialysis set includes a rack 810, a second support module 830 and a storage cassette 840 provided on the rack 810, and a first support module and/or other modules (e.g., environmental sterilization modules, etc.) that are not shown.

In addition, the bracket 810 and the second supporting module 830 are both fixedly connected to the base 860. The base 860 has a certain weight so as to stably support the stand 810 in a substantially vertical standing or a slightly angled inclined standing. In the embodiment shown in fig. 8, the base 860 is frame-shaped and generally surrounds the second support module 830. In some other embodiments, the base may also be plate-like or other similar shape and located below the second support module.

The second support module 830 includes a load-bearing platform 832 and a tray 834, wherein the load-bearing platform 832 is secured to the base 860 and/or the stand 810, and the tray 834 is supported above the load-bearing platform 832. In some embodiments, the tray 834 may be fixedly attached to the load-bearing platform 832. In other embodiments, tray 834 may also be removably attached to load-bearing platform 832. For example, a magnet may be disposed on the tray 834 and/or the load-bearing platform 832, and the magnet may provide a magnetic force to interconnect the tray 834 and the load-bearing platform 832. When an operator needs to remove tray 834 (e.g., when tray 834 needs to be cleaned), he or she may apply a large force to tray 834, thereby separating tray 834 from load-bearing platform 832.

The second support module 830 is adapted to support a second container for collecting a second fluid drawn from the patient. Specifically, the second container may be placed on the tray 834. Since direct access to the second container is possible, in some embodiments, a temperature sensor is also integrated on the tray 834, for example, being disposed on an upper surface of the tray 834. With the temperature sensor, the temperature of the liquid in the second container can be detected. In this way, the temperature of the second fluid withdrawn from the patient may be determined and the associated temperature data may be sent to a control module (not shown). The temperature of the fluid withdrawn from the patient's body reflects the body temperature and thus may indicate to some extent his health. For example, when a high fluid temperature is detected, it is likely that an infection has occurred in the abdominal cavity of the patient, requiring treatment. Accordingly, the control module may further integrate corresponding temperature data processing software to process the temperature data. For example, the temperature data processing software may compare the detected liquid temperature to a predetermined temperature threshold. If the fluid temperature is below the temperature threshold, it indicates that the patient is not at risk of developing an abdominal infection, and if the fluid temperature is above the temperature threshold, it indicates that the patient is at risk of developing an abdominal infection. In this case, the temperature data processing software may generate a corresponding alarm signal to prompt the patient or the doctor.

It should be noted that although several modules or sub-modules of the peritoneal dialysis set are mentioned in the above detailed description, such division is merely exemplary and not mandatory. Indeed, according to embodiments of the application, the features and functions of two or more modules described above may be embodied in one module. Conversely, the features and functions of one module described above may be further divided into embodiments by a plurality of modules.
