Description

Analyte Detection Systems Technical Field

The present invention mainly relates to the field of medical devices, and in particular to an analyte detection system.

Background Art

The pancreas in a normal person's body can automatically monitor the glucose content in the human blood and automatically secrete the required insulin/glucagon. However, the pancreas of diabetic patients has abnormal function and cannot normally secrete the insulin required by the human body. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function in the human body, and diabetes is a lifelong disease. At present, medical technology cannot cure diabetes, and can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar.

Diabetic patients need to test their blood sugar before injecting insulin. Currently, most testing methods can continuously test blood sugar and send blood sugar data to remote devices in real time for users to view. This testing method is called continuous glucose monitoring (CGM). This method requires the detection device to be attached to the surface of the skin and the sensor probe it carries is inserted into the subcutaneous tissue fluid to complete the test.

The iteration of analyte detection devices is often accompanied by changes in size, and the analyte detection devices need to be installed on the user's skin surface with the help of an auxiliary installer.

When adjusting the structure of the auxiliary installer, how to reduce design, production costs and cycles is a problem that needs to be considered.

Therefore, the prior art urgently needs an analyte detection system that can reduce design, production costs and cycles during version iterations.

DETAILED DESCRIPTION

As mentioned above, the prior art urgently needs an analyte detection system that can reduce design, production costs and cycles during version iterations.

In order to solve this problem, the present invention provides an analyte detection system, in which an emitter and a bottom shell are releasably connected. After the user installs the disposable bottom shell on the skin surface through an auxiliary installer, the reusable emitter is assembled on the bottom shell to form a complete analyte detection device. Before installing the bottom shell, the bottom shell and a parallel slider in the auxiliary installer are releasably connected. When the version of the analyte detection device is iterated, if the size of the bottom shell changes, only the structure of the parallel slider needs to be changed, and the auxiliary installer can be suitable for bottom shells of different sizes, thereby meeting the version iteration requirements of the analyte detection device and reducing the design and production costs and cycles.

It should be noted that like reference numerals and letters denote similar items in the following figures, and thus, once an item is defined or described in one figure, it will not require further discussion in the subsequent figure descriptions.

Figure 1a is a schematic diagram of the structure of the auxiliary installation device according to an embodiment of the present invention. Figure 1b is a schematic diagram of the structure of the analyte detection device and the auxiliary installation device according to an embodiment of the present invention. Figure 1c is a schematic diagram of the structure of the puncture structure, the parallel slider and the bottom shell according to an embodiment of the present invention.

In one embodiment of the present invention, the auxiliary installation device 20 includes a housing 201 and a protective cover 202. The analyte detection device 10 is located in the housing 201. When installation is required, the user unscrews the protective cover 202 from the housing 201 and presses the housing 201 against the skin surface to install the analyte detection device 10 on the skin surface. In the embodiment of the present invention, components such as sensors, antennas, circuit boards, and batteries are all arranged in the housing of the analyte detection device 10 to form an integrated structure.

In another embodiment of the present invention, the housing 201 of the auxiliary mounter 20 only contains the bottom housing 101 of the analyte detection device 10. When installation is required, the housing 201 is pressed against the skin surface to install the bottom housing 101 on the skin surface, and then the transmitter 102 is assembled on the bottom housing 101. In the embodiment of the present invention, the antenna and the circuit board are arranged in the transmitter 102, and the sensor and the battery are arranged on the bottom housing 101, forming a separate structure. In the embodiment of the present invention, the bottom housing 101 is disposable, and the transmitter 102 is reusable.

In some embodiments of the present invention, before installation, the bottom shell 101 and the auxiliary installer 20 can be released from the connection. The bottom shell 101 is circular or approximately circular, and has a central axis l2, and the auxiliary installer has a central axis l1. In some embodiments of the present invention, the central axes l1 and l2 coincide. In other embodiments of the present invention, the central axes l1 and l2 do not coincide.

In some embodiments of the present invention, the auxiliary installer 20 also includes a parallel slider 203. Before installation, the bottom shell 101 and the parallel slider 203 can be releasably connected. A groove 2031 is provided on the parallel slider 203 for accommodating the bottom shell 101. The shape of the groove 2031 is adapted to the shape of the bottom shell 101, and is also circular or approximately circular, and shares a central axis with the bottom shell 101. During the version iteration process of the analyte detection device 10, no matter how the size of the bottom shell 101 changes, the size of the groove 2031 on the parallel slider 203 changes adaptively.

1c, in some embodiments of the present invention, as the analyte detection device 10 is iterated, the auxiliary installer 20 can be adapted to different versions of the analyte detection device 10, so as to save the research and development, production costs and cycles of the auxiliary installer 20 and the analyte detection device 10, and different versions of the analyte detection device 10 often has different sizes, based on which, some adaptive modifications need to be made to the structure of the analyte detection device 10.

For example, in some embodiments of the present invention, when the bottom shell 101 of some larger-sized analyte detection devices 10 is fixed on the parallel slider 203 through the groove 2031, the central axis l2 of the bottom shell 101 coincides with the central axis l1 of the auxiliary mounter 20 (the central axis of the parallel slider 203). At this time, the groove 2031 is also coaxial with the auxiliary mounter 20 and the bottom shell 101, and the puncture structure 204 (such as a steel needle) is coaxial with the sensor 1032 to accommodate the sensor 1032. When the auxiliary mounter 20 is changed to adapt to a smaller-sized bottom shell 101, if the position of the puncture structure 204 on the auxiliary mounter 20 remains unchanged, that is, the sensor 10 If the position of the bottom shell 101 and the auxiliary mounter 20 remain unchanged, the central axis l2 of the bottom shell 101 will deviate from the central axis l1 of the auxiliary mounter 20 and approach the position of the puncture structure 204, and the two will no longer overlap. At this time, the parallel slider 203 needs to be structurally improved, for example, the groove 2031 is moved closer to the puncture structure 204 as a whole, and its circumference is also adaptively reduced with the bottom shell 101, so that the groove 2031 can accommodate the bottom shell 101, while the puncture structure 204 can still pass through the bottom shell 101 and accommodate the sensor 1032. At this time, the central axis of the groove 2031 will deviate from the central axis l1 of the auxiliary mounter 20 and be in an eccentric position relative to the parallel slider 203. Alternatively, in other embodiments of the present invention, if the central axes of the bottom shell 101 and the auxiliary mounter 20 are kept coincident, that is, the position of the groove 2031 remains unchanged, at this time, the position of the puncture structure 204 needs to be moved closer to the central axis l2 of the bottom shell 101. Since the puncture structure 204 is fixed inside the shell 201, it is necessary to change the internal shell structure of the shell 201. For the auxiliary installer 20, it is easier to change the position of the groove 2031 of the parallel slider 203 than to change the position of the puncture structure 204, and the design and production modification costs are lower and the cycle is shorter. Therefore, in the preferred embodiment of the present invention, in order to adapt to the smaller size of the analyte detection device 10, it is sufficient to adaptively change the size of the groove 2031 and the position on the parallel slider 203.

Figure 2a is a schematic diagram of the structure of the analyte detection device according to an embodiment of the present invention. Figures 2b to 2c are schematic diagrams of the exploded structures of the analyte detection devices according to different embodiments of the present invention. Figure 3 is a schematic diagram of the structure of the transmitter according to an embodiment of the present invention. Figure 4 is a schematic diagram of the structure of the bottom shell according to an embodiment of the present invention.

In some embodiments of the present invention, the analyte detection device 10 includes a base housing 101 , a transmitter 102 and a sensor module 103 .

In some embodiments of the present invention, the bottom shell 101 and the transmitter 102 are releasably connected. The bottom shell 101 includes at least one first engaging portion 1011, and the transmitter 102 is provided with at least one second engaging portion 1021 at a corresponding position. The first engaging portion 1011 and the second engaging portion 1021 can engage with each other, so that the transmitter 102 can be fixed on the bottom shell 101.

In some embodiments of the present invention, the first engaging portion 1011 and the second engaging portion 1021 may be engaged in a manner such as a hook and a slot, a hook and a hole, or a hook and a hook, which is not limited here.

In some embodiments of the present invention, after the first engaging portion 1011 and the second engaging portion 1021 are engaged with each other, the transmitter 102 and the bottom shell 101 can maintain a good fixed connection, and the transmitter 102 will not be easily separated from the bottom shell 101.

In some embodiments of the present invention, since the analyte detection device 10 is circular or approximately circular, the side walls of the bottom shell 101 and the emitter 102 are both curved or arc-shaped, and the two are compatible in shape and size.

In some embodiments of the present invention, at least two first engaging portions 1011 are symmetrically arranged on the curved side wall of the bottom shell 101 to constrain the transmitter 102 , and correspondingly, at least two second engaging portions 1021 are arranged at corresponding positions on the curved side wall of the transmitter 102 .

In one embodiment of the present invention, in order to more securely constrain the transmitter 102 to the bottom shell 101, at least two third clamping parts 1012 and at least two fourth clamping parts 1022 may be respectively provided on the bottom shell 101 and the transmitter 102, and the position, shape and number of the fourth clamping parts 1022 correspond to those of the third clamping parts 1012.

In some embodiments of the present invention, since the bottom shell 101 is circular or approximately circular in shape, the third engaging portions 1012 are also distributed on the arc-surface sidewall of the bottom shell 101 .

In some embodiments of the present invention, the third engaging portions 1012 are symmetrically distributed on the side wall of the bottom housing 101 .

In one embodiment of the present invention, with the bottom shell 101 shown in FIG. 2a as a reference, the first engaging portion 1011 and the third engaging portion 1012 are both located on the side wall of the bottom shell 101, the first engaging portion 1011 is located at the left end of the side wall of the bottom shell 101, and the third engaging portion 1012 is located in the middle of the side wall of the bottom shell 101. The above positions are determined by the specific shape of the transmitter 102, so that the two ends of the transmitter 102 can be respectively fixed on the bottom shell 101, thereby maintaining a tight snap connection between the transmitter 102 and the bottom shell 101. Therefore, it can be expected that when the shape of the transmitter 102 changes, the position, shape and number of the first engaging portion 1011 (the second engaging portion 1021) and the third engaging portion 1012 (the fourth engaging portion 1022) will also change adaptively. No matter how their positions, shapes and numbers change, they should be included in the protection scope of the present invention.

In some embodiments of the present invention, the third engaging portion 1012 is disposed on the curved side wall of the bottom shell 101, as shown in Fig. 3. In other embodiments of the present invention, the third engaging portion 1012 is disposed on the bottom surface of the bottom shell 101. In still other embodiments of the present invention, the third engaging portion 1012 can be disposed on the curved side wall and the bottom surface of the bottom shell 1012 at the same time, which is not limited here.

In a preferred embodiment of the present invention, the bottom shell 101 is provided with a first snap-fitting portion 1011 and a third snap-fitting portion 1012, and correspondingly, the transmitter 102 is provided with a second snap-fitting portion 1021 and a fourth snap-fitting portion 1022, and the position, shape and number of the second snap-fitting portion 1021 and the fourth snap-fitting portion 1022 are respectively adapted to the first snap-fitting portion 1011 and the third snap-fitting portion 1012.

In some embodiments of the present invention, the transmitter 102 can be stably fixed on the bottom shell 101 by the first engaging portion 1011 and the third engaging portion 1012 respectively engaging with the second engaging portion 1021 and the fourth engaging portion 1022. Since the transmitter 102 is reusable, when the user replaces a new analyte detection device 10, the transmitter 102 needs to be removed from the bottom shell 101. For this purpose, a solution is designed in which the bottom shell 101 can be bent and fail. When the bottom shell 101 is bent and fails, the engagement of the first engaging portion 1011 with the second engaging portion 1021 or/and the engagement of the third engaging portion 1012 with the fourth engaging portion 1022 are decoupled, thereby separating the transmitter 102 and the bottom shell 101. See below for details.

In some embodiments of the present invention, in order to allow the bottom shell 101 to bend and fail, the bottom shell 101 needs to be made of flexible materials, such as PE or PP plastic. The bottom shell 101 needs to be attached to the user's skin surface, such as the arm or stomach, during use. The user's skin surface is constantly moving or bending during daily activities, and the overly soft bottom shell 101 will also bend, which will cause the first clamping part 1011 and the second clamping part 1021 or/and the third clamping part 1012 and the fourth clamping part 1022 to be decoupled with a certain probability, causing the transmitter 102 and the bottom shell 101 to become loose. Based on this, the bottom shell 101 cannot be too soft.

In some embodiments of the present invention, a crease groove 1016 is provided on the bottom shell 101, so that the bottom shell 101 can maintain a certain rigidity while being convenient for users to bend the bottom shell 101, so that the coupling part can be decoupled after the bottom shell 101 fails. The bottom surface thickness at the crease groove 1016 is slightly thinner than other bottom surfaces. For example, when the thickness of the bottom shell 101 is 0.5-1.0 mm, the bottom surface at the crease groove 1016 is relatively reduced by 0.01-0.7 mm, or the bottom surface at the crease groove 1016 is half hollow (no bottom shell material is provided at the hollow part, and the bottom surface thickness is 0 mm here), that is, the bottom surfaces on both sides of the crease groove 1016 are intermittently connected by the bottom shell 101 material, or the crease groove 1016 is not provided on the bottom surface of the bottom shell 101, but the bottom surface of the bottom shell 101 is only provided with a half-hollow structure, and the bottom surfaces of the bottom shells on both sides are connected, which can also facilitate users to bend the bottom shell 101.

Referring to Figure 4, in some embodiments of the present invention, taking the illustrated x-y coordinate as a reference, the x-y coordinate is the plane coordinate of the bottom shell 101, and the crease groove 1016 is a linear groove parallel to the x-axis. When the user bends the bottom shell 101, the bottom surface of the bottom shell 101 on both sides of the crease groove 1016 warps in a direction perpendicular to the x-y coordinate plane.

In other embodiments of the present invention, the crease groove 1016 is composed of a straight portion 10161 and a curved portion 10162, forming an A-A' track as shown in FIG4, wherein the straight portion 10161 is parallel to the x-axis, and the curved portions 10162 are distributed at both ends of the straight portion 10161. The groove of the straight portion 10161 can facilitate the bending of the bottom shell 101, and the curved portion 10162 can also facilitate the bending of the bottom shell 101. The difference is that the curved portion 10162 has a portion that is at a certain angle to the x-axis, which can increase the bending strength of the crease groove 1016, increase the rigidity design redundancy of the bottom shell 101, make the crease groove 1016 not easy to bend during daily use, and improve the launch efficiency. The connection stability between the device 102 and the bottom shell 101 is improved.

In some embodiments of the present invention, the fold groove 1016 can also be used in conjunction with the third engaging portion 1012 and the fourth engaging portion 1022 to complete the engagement and separation of the bottom shell 101 and the transmitter 102, as described in detail below.

In some embodiments of the present invention, the bottom surface of the straight portion 10161 or the curved portion 10162 may also be half hollow, that is, the bottom surfaces on both sides of the straight portion 10161 or the curved portion 10162 are discontinuously connected by the material of the bottom shell 101, and the unconnected parts are completely removed, which can reduce the overall weight of the analyte detection device 10.

Figures 5a and 5b are schematic diagrams of the structure of the bottom shell before and after failure of the embodiment of the present invention. Figures 5c and 5d are schematic diagrams of the structure of the third engaging portion of the bottom shell before and after failure of the embodiment of the present invention.

In some embodiments of the present invention, no matter the fold groove 1016 is a straight groove or a straight and curved combination groove, both ends thereof correspond to the third engaging portion 1012 and the fourth engaging portion 1022 .

In some embodiments of the present invention, the bottom shell 101 includes a fixing portion and a force-applying portion. When the user bends the bottom shell 101 to separate the transmitter 102, the user needs to fix the fixing portion with a finger and apply a pressure F to the force-applying portion. The bottom shell 101 can bend along the crease groove 1016 or fail to bend. At this time, the third clamping portion 1012 and the fourth clamping portion 1022 are decoupled. Here, the fixing portion and the force-applying portion are relative concepts, which will be described in detail below.

In some embodiments of the present invention, failure is a conventional concept in the field of engineering materials. After failure, the material loses its original function and the failed part cannot be restored again. Since the third engaging portion 1012 is a part of the bottom shell 101, the failure of the bottom shell 101 includes the failure of the bottom surface, side wall or third engaging portion 1012 of the bottom shell 101. Therefore, the failure modes of the bottom shell 101 include the breakage of the bottom shell 101, the bending deformation of the bottom shell 101, and the breakage of the third engaging portion 1012. Obviously, after the bottom shell 101 fails, the bottom shell 101 loses the function and role of engaging the transmitter 102.

In some embodiments of the present invention, the method of fixing the fixing part includes clamping, supporting, etc., which is not specifically limited here, as long as the conditions for fixing the fixing part are met. Specifically, the fold groove 1016 divides the bottom shell into two sides, one side is used as the fixing part, and the other side is used as the force applying part. The fixing part and the force applying part can be interchangeable.

5a and 5b, in some embodiments of the present invention, the process of separating the bottom shell 101 and the transmitter 102 is as follows: fix the fixing part with a finger, and use another finger to apply a force F to the force-applying part in one direction, so that the bottom shell 101 is bent or curved, and the fourth clamping part 1022 is disengaged from the clamping of the third clamping part 1012 and decoupled, so that the transmitter 102 is separated from the bottom shell 101. Obviously, the bottom shell 101 is bent or curved along the crease groove 1016. The cooperation between the crease groove and the third and fourth clamping parts enables the transmitter and the bottom shell to be better separated. Leave.

5c and 5d, in some embodiments of the present invention, the process of separating the bottom shell 101 and the transmitter 102 is as follows: fix the fixing portion with a finger, and use another finger to apply a force F to the force-applying portion in one direction to invalidate the third clamping portion 1012, thereby separating the third clamping portion 1012 and the fourth clamping portion 1022, so that the transmitter 102 is separated from the bottom shell 101.

In some embodiments of the present invention, a battery cavity 1013 is further provided on the bottom shell 101 , and a battery is installed in the battery cavity 1013 to provide electrical energy for the analyte detection device 10 .

With reference to FIG. 2a , in some embodiments of the present invention, the battery cavity 1013 serves as a force-applying portion, and the transmitter 102 serves as a fixing portion. When separating the transmitter 102 and the bottom shell 101, the user fixes the transmitter 102 with one finger, and applies a force F to the battery cavity 1013 with another finger, so that the battery cavity 1013 bends along the direction of curve a, and the fourth engaging portion 1022 has a movement tendency in the direction of curve d relative to the battery cavity 1013. As the force is continuously applied to the battery cavity 1013, the bottom shell 101 bends and deforms, and the bottom shell 101 no longer presses against the fourth engaging portion 1022, and the transmitter 102 moves along the direction of curve b relative to the battery cavity 1013. The fourth engaging portion 1022 is moved in the direction of the line and the direction of the c curve until the fourth engaging portion 1022 is decoupled from the third engaging portion 1012. At this time, since the first engaging portion 1011 and the second engaging portion 1021 are not completely decoupled, the transmitter 102 and the bottom shell 101 are in a semi-connected state, which can prevent the transmitter 102 from falling off during the disassembly process. The user only needs to hold the transmitter 102 with his fingers to release the engaging state of the first engaging portion 1011 and the second engaging portion 1021 to complete the disassembly of the transmitter 102, which is easy to operate.

As mentioned above, the force-applying part and the fixing part are relative. In other embodiments of the present invention, the transmitter 102 serves as the force-applying part and the battery cavity 1013 serves as the fixing part, and the disassembly process is the same.

In some embodiments of the present invention, the battery cavity 1013 further includes a detachable cavity cover 10132. The detachable cavity cover 10132 is used to assemble the battery or electrolyte into the battery cavity 1013 during the production process. After the production is completed, the cavity cover 10132 is fixed on the battery cavity 1013 and sealed to prevent dirt such as water droplets from entering the battery cavity 1013. After the cavity cover 10132 is sealed, the adhesive tape 1015 is adhered and fixed to the bottom shell 101, and the cavity cover 10132 is covered by the adhesive tape 1015.

In some embodiments of the present invention, the cavity cover 10132 is connected to the cavity shell 10131 by means of bonding, snapping, welding, etc., so as to be fixed on the battery cavity 1013. It is understandable that the cavity cover 10132 is releasably connected to the cavity shell 10131 before production, or is in a separated state. After the battery is installed, the cavity cover 10132 is fixedly connected to the cavity shell 10131, and the cavity cover 10132 and the cavity shell 10131 can be completely sealed. The cavity cover 10132 cannot be removed again, so as to prevent the cavity cover 10132 from loosening and external dirt from entering the battery cavity 1013.

In some embodiments of the present invention, the battery is an independent button battery, and the battery is accommodated in the battery cavity 1013.

In some embodiments of the present invention, the positive electrode and the negative electrode of the battery are electrically connected to the elastic conductor 1014 respectively, and the other end of the elastic conductor 1014 is electrically connected to the second electrical connection area 1024 of the transmitter 102. The elastic conductor 1014 serves as a conductive carrier, so that the battery can provide electrical energy to the transmitter 102. The second electrical connection area 1024 is compatible with the elastic conductor 1014, and the number of the second electrical connection area 1024 is the same.

In some embodiments of the present invention, when the transmitter 102 is assembled to the bottom shell 101, the second electrical connection area 1024 contacts and compresses the elastic conductor 1014. The elastic conductor 1014 in the compressed state can be in closer contact with the second electrical connection area 1024. Secondly, when the transmitter 102 is disassembled, after the third clamping portion 1012 and the fourth clamping portion 1022 are decoupled, the elastic force of the elastic conductor 1014 can also help separate the transmitter 102 from the bottom shell 101.

In some embodiments of the present invention, the elastic conductor 1014 may be a conductive spring, conductive rubber, etc.

In some embodiments of the present invention, the second electrical connection region 1024 is a metal contact.

In other embodiments of the present invention, the battery cavity 1013 itself serves as a battery body to provide electrical energy to the analyte detection device 10, as shown in FIG. 6 for details.

Fig. 6 is a schematic diagram of the X-X' cross-sectional structure of the battery cavity in Fig. 2b of an embodiment of the present invention.

In some embodiments of the present invention, the battery cavity 1013 includes a cavity shell 10131, and the cavity shell 10131 is integrally formed with the bottom shell 101, so that the analyte detection device 10 is more miniaturized.

The cavity shell 10131 is used to accommodate and fix the above structure, and the positive electrode sheet 10135 and the negative electrode sheet 10136 are immersed in the electrolyte 10134 and separated by the diaphragm 10133 in the middle. According to the above structure, the battery cavity 1013 itself can be used as a complete battery to provide power for the analyte detection device 10. The cavity shell of the battery cavity is used as the battery shell, eliminating the shell of an independent battery. The battery cavity 1013 can be more miniaturized and can accommodate more electrolyte 10131, store more power, and extend the life of the analyte detection device 10. In some embodiments of the present invention, the diaphragm 10133, the positive electrode sheet 10135, and the negative electrode sheet 10136 are wound structures, and the diaphragm 10133 is located between the positive electrode sheet 10135 and the negative electrode sheet 10136.

In some embodiments of the present invention, the separator 10133, the positive electrode sheet 10135 and the negative electrode sheet 10136 are a stacked planar structure, and the separator 10133, the positive electrode sheet 10135 and the negative electrode sheet 10136 are spaced apart from each other.

In some embodiments of the present invention, the solute of the electrolyte 10134 is a lithium salt, such as one of lithium perchlorate (LiClO4), lithium hexafluorophosphate (LiPF6), and lithium tetrafluoroborate (LiBF4). The solvent is one of ethylene carbonate, propylene carbonate, diethyl carbonate, dimethyl carbonate, ethyl methyl carbonate, phosphorus pentafluoride, hydrofluoric acid, ether, ethylene carbonate, propylene carbonate, and diethyl carbonate. In a preferred embodiment, the solvent is an organic solvent, such as one of ether, ethylene carbonate, propylene carbonate and diethyl carbonate.

In some embodiments of the present invention, the main material of the positive electrode plate 10135 is manganese dioxide, and is made by the following manufacturing process:

① Screening of electrolytic manganese dioxide, conductive agent and binder can be done by screen or airflow classifier, and electrolytic manganese dioxide particles with a particle size less than 200um are selected, placed in a quartz boat, and heat treated in a sintering furnace at a temperature of 200°C for 4 hours. The purpose of this step is to make the electrolytic manganese dioxide lose some of its bound water, shift the X-ray diffraction peak, reduce the interplanar spacing, and enhance the Mn-O bonding force, thereby enhancing the discharge capacity of the electrolytic manganese dioxide.

② After cooling the electrolytic manganese dioxide in step ① to below 60°C, 9g of electrolytic manganese dioxide, 0.5g of a conductive agent with a particle size of less than 200um, and 0.5g of a binder with a particle size of less than 200um are weighed using an electronic balance, placed in a grinding dish, fully stirred and mixed, and then ground manually or electrically to obtain 10g of a ground mixture, and the ground mixture is allowed to pass through a 300-mesh (particle size 48um) sieve. The purpose of this step is to ensure the uniformity of the mixture and avoid uneven dispersion of the conductive agent and additives.

In other embodiments of the present invention, the mass proportions of electrolytic manganese dioxide, conductive agent and binder are not limited to the above proportions, and their mass proportions may be 80%-96%, 2%-10% and 2%-10% respectively.

In a preferred embodiment of the present invention, the conductive agent can be one or more of conductive carbon black, graphite, super p or carbon nanotubes.

In a preferred embodiment of the present invention, the binder may be one or more of PVDF (polyvinylidene fluoride), polytetrafluoroethylene, and sodium polyacrylate.

③ Place the ground mixture in a vacuum oven and heat to 65°C for 5 hours to dry out any moisture that may be present in the mixture and ensure that the sample is dry to obtain a positive electrode mixture.

④ Add 10g of NMP (N-methylpyrrolidone) solvent to a dry glass bottle, then slowly add the positive electrode mixture to the glass bottle and stir with a magnetic stirrer for 3 hours to ensure that the mixture is uniform, and obtain a positive electrode slurry with a solid content of 50%. The purpose of this step is to ensure that the components in the positive electrode slurry are evenly dispersed, and the solid content has a certain relationship with the viscosity of the positive electrode slurry. The positive electrode slurry with a solid content of 50% has a better viscosity, and the film-forming effect after coating on the substrate is better, which can reduce the phenomenon of powder loss or cracking.

⑤ Use a flat plate coating machine to coat the positive electrode slurry on the surface of the substrate to obtain a conductive layer, and then place the conductive layer and the substrate in a vacuum oven and bake them at 110°C for 12 hours to ensure that the moisture is completely dried.

In a preferred embodiment of the present invention, the base material is one of aluminum foil or nickel foam mesh, with a thickness of 12-18um.

In a more preferred embodiment of the present invention, the base material is aluminum foil with a thickness of 15 um.

⑥ Use an electric vertical roller press to roll the conductive layer and the substrate, which can reduce the overall thickness of the conductive layer and the substrate to 180-220um to obtain a finished positive electrode sheet. By adjusting the working parameters of the coating machine and the roller press, the thickness of the positive electrode sheet can be controlled to ensure that the electrode sheet has a relatively complete conductive network under the premise of a high compaction density, so as to meet the working requirements of high current pulse discharge.

In the embodiment of the present invention, the negative electrode plate 10136 is mainly made of lithium-based material.

In other embodiments of the present invention, the positive electrode plate 10135 may also be a lithium-containing compound such as lithium manganese oxide, lithium cobalt oxide, lithium iron phosphate, etc., and the corresponding negative electrode plate 10136 is graphite.

In the embodiment of the present invention, the material of the diaphragm 10133 is PE (polyethylene) or PP (polypropylene), which can be a single layer of PE or PP or three layers of PE or PP.

In some embodiments of the present invention, one end A of the conductive sheet 10138 is fixedly connected to the positive electrode sheet 10135 or the negative electrode sheet 10136, and the other end B of the conductive sheet 10138 passes through the electrolyte isolation layer 10137 and the cavity shell 10131, and is electrically connected to the elastic conductor 1014. In a preferred embodiment of the present invention, the end A is fixedly connected to the positive electrode sheet 10135 or the negative electrode sheet 10136 by solder or solder paste.

In the embodiment of the present invention, the conductive sheet 10138 connected to the positive electrode plate 10135 is made of aluminum, and the conductive sheet 10138 connected to the negative electrode plate 10136 is made of nickel or nickel-plated copper.

In some embodiments of the present invention, the material of the cavity shell 10131 is generally plastic, such as PE (polyethylene), PP (polypropylene) or PC (polycarbonate), which is easily corroded by the electrolyte 10134. Therefore, it is necessary to set an electrolyte isolation layer 10137 inside the cavity shell 10131.

In some embodiments of the present invention, the electrolyte isolation layer 10137 is TPE (butyl rubber) or PET (polyethylene terephthalate). TPE is a thermoplastic elastomer material with strong processability. The PET material itself is used as a container for the electrolyte and can effectively isolate the corrosion of the cavity shell by the electrolyte.

In the embodiment of the present invention, the electrolyte isolation layer 10137 can be a thin film coated on the inner side of the cavity shell 10131 by a deposition method or a solution method, or it can be a separate closed shell.

In a preferred embodiment of the present invention, the electrolyte isolation layer 10137 is a thin film with a thickness of 300-500um. If the thickness of the electrolyte isolation layer 10137 is too small, the film material will be infiltrated and softened by the electrolyte, which will cause the film material to age after a long time. If the thickness is too large, it will occupy the internal space of the chamber. In a more preferred embodiment of the present invention, the thickness of the electrolyte isolation layer 10137 is 400um.

In some embodiments of the present invention, if the cavity shell 10131 is made of a material resistant to corrosion by the electrolyte 10134, such as PFA (polytetrafluoroethylene) or FEP (polyperfluoroethylene propylene), the electrolyte isolation layer can be omitted. Layer 10137 increases the volume of electrolyte 10134 and improves battery energy storage.

In some embodiments of the present invention, a sensor module is further provided on the bottom shell 101 . The sensor module includes an elastic sealing ring 1031 , a sensor 1032 , and a conductive rubber strip 1033 . The sensor 1032 includes an internal part 10321 and an external part 10322 .

In some embodiments of the present invention, the elastic sealing ring 1031 is an annular structural member, and the external part 10322 and the conductive rubber strip 1033 are both located in the inner circle of the elastic sealing ring 1031. When the transmitter 102 is assembled on the bottom shell 101, with reference to the direction of FIG. 2b, the lower end surface of the elastic sealing ring 1031 contacts the bottom surface of the bottom shell 101, and the upper end surface contacts the shell of the transmitter 102, forming a completely closed space in the inner circle of the elastic sealing ring 1031, and the external part 10322 and the conductive rubber strip 1033 are in this closed space. The closed space of the elastic sealing ring 1031 can prevent dirt such as water droplets, metal chips, and blood from entering, avoiding contamination of the external part 10322 and the conductive rubber strip 1033, and affecting the detection signal.

Figure 7a is a schematic diagram of the structure of the conductive rubber strip according to an embodiment of the present invention. Figure 7b is a schematic diagram of the structure of a conductive rubber strip according to an embodiment of the present invention where one structural surface is sealed. Figures 7c to 7f are schematic diagrams of the structure of the sensor and the conductive rubber strip assembled on the bottom shell according to an embodiment of the present invention. Figure 7g is a schematic diagram of the structure of the conductive area of the conductive rubber strip according to an embodiment of the present invention where the conductive area is sealed.

Referring to FIG. 7a, in an embodiment of the present invention, the conductive rubber strip 1033 is a three-dimensional structure having multiple structural surfaces, such as a rectangular parallelepiped structure. The conductive rubber strip 1033 has conductive areas and insulating areas that are spaced apart in the longitudinal length, and both the conductive areas and the insulating areas run through the lateral direction of the conductive rubber strip 1033, where the lateral direction is perpendicular to the longitudinal direction. Since both the conductive areas and the insulating areas run through the lateral direction of the conductive rubber strip 1033, the four side structural surfaces 1033a, 1033b, 1033c, and 1033d of the conductive rubber strip 1033 all have conductive areas and insulating areas, and it can be understood that the corresponding conductive areas on the four side structural surfaces 1033a, 1033b, 1033c, and 1033d are electrically connected.

In some embodiments of the present invention, the conductive area and the insulating area are distributed at intervals. The insulating area can separate two adjacent conductive areas. The insulating area has good insulating properties, which can prevent crosstalk between electrical signals of two adjacent conductive areas and ensure the stability of the detection signal.

In some embodiments of the present invention, the conductive rubber strip 1033 is used to electrically connect the sensor 1032 and the transmitter 102. Specifically, the transmitter includes a first electrical connection area 1023, and the first electrical connection area 1023 includes at least two metal contacts 10231. At least two pins (not shown in the figure) are provided on the external part 10322 of the sensor 1032. Each metal contact 10231 is respectively in contact with a different conductive area on a single structural surface of the conductive rubber strip 1033. At the same time, the corresponding conductive areas of the above-mentioned conductive areas on the same, adjacent or opposite structural surfaces are in contact with the pins, thereby realizing the electrical connection between the pins and the metal contacts 10231. The detection signal of the sensor 1032 can be transmitted to the transmitter 102 through the conductive rubber strip 1033, and the transmitter 102 can also be transmitted through The control signal is transmitted to the sensor 1032 via the conductive rubber strip 1033 .

In some embodiments of the present invention, the number of metal contacts 10231 is the same as the number of pins.

In some embodiments of the present invention, the metal contact 10231 establishes an electrical connection with the external part 10322 through the relative structural surfaces of the conductive rubber strip 1033, i.e., 1033a, 1033c or 1033b, 1033d, forming a stacked structure of the external part 10322-conductive rubber strip 1033-metal contact 10231. At this time, the external part 10322 is laid flat on the bottom surface of the bottom shell 101 in a parallel state, as shown in Figure 7c.

In some embodiments of the present invention, the metal contact 10231 and the external part 10322 establish electrical connection through adjacent structural surfaces of the conductive rubber strip 1033, such as the external part 10322 is electrically connected to the side structural surface 1033c of the conductive rubber strip 1033, and the metal contact 10231 is electrically connected to the upper structural surface 1033d. At this time, the external part 10322 is laid flat on the bottom surface of the bottom shell 101 in a vertical state, as shown in Figure 7d.

The above embodiment is for illustration only, and other adjacent structural surfaces can also realize the electrical connection function. Compared with the stacked structure of the external part 10322 - conductive rubber strip 1033 - metal contact 10231, the electrical connection of adjacent structural surfaces can reduce the overall thickness, which is conducive to the miniaturization design of the analyte detection device 10.

7e and 7f, in some embodiments of the present invention, in order to further reduce the overall thickness of the analyte detection device 10, a pit 1017 may be further provided on the bottom shell 101, and the external part 10322 or the conductive rubber strip 1033 may be placed in the pit 1017. The external part 10322 or the conductive rubber strip 1033 may be placed in the pit 1017, and the external part 10322 or the conductive rubber strip 1033 may be fixed by interference fitting the external part 10322 or the conductive rubber strip 1033 with the pit 1017, thereby improving the assembly stability of the sensor 1032 or the conductive rubber strip 1033.

In some embodiments of the present invention, referring to the direction shown in FIG. 2 b , the external portion 10322 is electrically connected to the side structural surface 1033 c of the conductive rubber strip 1033 , and the first electrical connection area 1023 of the transmitter 102 is electrically connected to the upper structural surface 1033 d of the conductive rubber strip 1033 .

With reference to Fig. 2a, Fig. 7b and Fig. 7d, in some embodiments of the present invention, there is also a conductive area on the unused structural surface, and the conductive area is continuous with the conductive area on the used structural surface. If the conductive area is short-circuited by dirt, it will also cause the conductive area on the used structural surface to short-circuit, affecting the stability of the detection signal. Therefore, it can be considered to seal the conductive area on the unused structural surface to prevent it from being short-circuited by dirt. For example, with reference to Fig. 7b, in some embodiments of the present invention, the external part 10322 is electrically connected to the side structural surface 1033c of the conductive adhesive strip 1033, and the first electrical connection area 1023 of the transmitter 102 is electrically connected to the upper structural surface 1033d of the conductive adhesive strip 1033. At this time, the side structural surface 1033a and the lower structural surface 1033b are not used, and an insulating material can be coated or pasted on the side structural surface 1033a and/or the lower structural surface 1033b to prevent the conductive areas on these two structural surfaces from being short-circuited by dirt. In the embodiment of the present invention, only 1033a is easily contaminated, so only 1033a can be coated or pasted, which can prevent the conductive area from being short-circuited by dirt and avoid insulation. Waste of edge materials.

With reference to Figures 2c, 7b and 7e, in some other embodiments of the present invention, the external part 10322 is electrically connected to the lower structural surface 1033b of the conductive rubber strip 1033, and the first electrical connection area 1023 of the transmitter 102 is electrically connected to the upper structural surface 1033d of the conductive rubber strip 1033. At this time, the side structural surfaces 1033a and 1033c are not used, and insulating material can be coated or pasted on the side structural surfaces 1033a and/or 1033c. Preferably, insulating material is coated or pasted on both the side structural surfaces 1033a and 1033c to prevent the conductive areas on these two structural surfaces from being short-circuited due to dirt.

In some embodiments of the present invention, the insulating material may be one or more of rubber, silicone, polyethylene, glass fiber, epoxy resin, and insulating varnish, as long as good insulating properties can be achieved.

In some embodiments of the present invention, the thickness of the insulating material is 1 to 1000 um, and preferably, the thickness of the insulating material is 10 to 100 um.

In some embodiments of the present invention, the insulating material may only cover the conductive area of the conductive rubber strip 1033, and may also achieve the function of insulating the non-electrically connected structural surface.

Referring to FIG. 7g, FIG. 7g is a top view of the conductive rubber strip 1033. In some embodiments of the present invention, the first electrical connection area 1023 of the transmitter 102 is electrically connected to the upper structural surface 1033d of the conductive rubber strip 1033. The conductive area on the upper structural surface 1033d that is not electrically connected to the first electrical connection area 1023 may also be contaminated by dirt and cause a short circuit. Based on this situation, the conductive area that is not electrically connected to the first electrical connection area 1023 may also be covered with an insulating material, and the insulating material is distributed at intervals on the upper structural surface 1033d. Alternatively, the external part 10322 is electrically connected to the side structural surface 1033c of the conductive rubber strip 1033. The conductive area on the side structural surface 1033c that is not electrically connected to the external part 10322 may also be contaminated by dirt and cause a short circuit. Therefore, the conductive area on the side structural surface 1033c that is not electrically connected to the external part 10322 may also be covered with an insulating material, and the insulating material is distributed at intervals on the side structural surface 1033c.

Since the conductive area and the insulating area on the conductive rubber strip 1033 are distributed at intervals, and the insulating material only needs to cover the conductive area to achieve its insulating function, in some embodiments of the present invention, the insulating material is covered on two adjacent conductive areas in a continuous form, and at the same time covers the insulating area between the two adjacent conductive areas. Alternatively, in other embodiments of the present invention, the insulating material is covered on two adjacent conductive areas in an interval form, and does not cover the insulating area between the two adjacent conductive areas.

In some embodiments of the present invention, the conductive rubber strip 1033 is covered with insulating material on the structural surface that is not electrically connected to other components, which can better avoid short circuit caused by dirt contamination and improve the stability of the detection signal.

In some embodiments of the present invention, the external portion 10322 is bent or folded relative to the internal portion 10321, and the internal portion 10321 is perpendicular or approximately perpendicular to the bottom shell 101 and passes through the bottom shell 101 so that To penetrate the user's subcutaneous tissue.

In some embodiments of the present invention, the external part 10322 is fixed to the bottom shell 101 through a sensor base. The sensor base and the bottom shell 101 are releasably connected. Before installation, the sensor base is separated from the bottom shell 101. During installation, the sensor base is assembled to the bottom shell 101.

In other embodiments of the present invention, the external portion 10322 is directly laid flat on the bottom surface of the bottom shell 101, eliminating the sensor base structure, making the internal structure of the analyte detection device 10 more compact and conducive to miniaturized design.

In summary, the present invention discloses an analyte detection system, in which an emitter and a bottom shell are releasably connected. After the user installs the disposable bottom shell on the skin surface through an auxiliary installer, the reusable emitter is assembled on the bottom shell to form a complete analyte detection device. Before installing the bottom shell, the bottom shell and a parallel slider in the auxiliary installer are releasably connected. When the version of the analyte detection device is iterated, if the size of the bottom shell is changed, only the structure of the parallel slider needs to be changed, and the auxiliary installer can be suitable for bottom shells of different sizes, thereby meeting the version iteration requirements of the analyte detection device and reducing the design and production costs and cycles.
