Description

Monitoring device

Technical Field

The present disclosure relates to the field of biomedical engineering industry, and in particular, to a monitoring device.

Background

Diabetes is a common chronic disease that is generally caused by insulin deficiency or poor insulin effects in the body. When blood glucose levels are at higher levels for long periods of time, other complications may occur that affect physical health, and monitoring blood glucose concentrations in real time is therefore particularly important. CGM (Continuous Glucose Monitoring) is a continuous blood glucose monitoring technique that generally includes a sensor assembly and an applicator electrically connected to the sensor assembly and applied to a user's body surface. The sensor assembly may be used to obtain analyte information (e.g., glucose concentration) within the user's body and be sent by the applicator to the user's smart device or terminal so that the user can timely grasp their blood glucose level. The sensor assembly may be generally divided into a sensor portion implanted subcutaneously in a user (may be simply referred to as an implanted portion) and a sensor portion not implanted subcutaneously in a user (may be simply referred to as a connected portion). The connection portion has a plurality of sensor electrical contacts thereon for electrical connection with a circuit board on the applicator for transmitting electrical signals.

In the prior art, a connector for stabilizing the connection portion and having a certain sealing effect is generally provided, and the connector may be used to electrically connect the sensor with the circuit board. Typically, the connector and circuit board are disposed on an upper housing of the applicator and the sensor assembly is disposed in a corresponding location on a lower housing of the applicator. When the upper shell and the lower shell are bonded, the connecting piece can enable the connecting part to be electrically connected with the circuit board to transmit electric signals while pressing the connecting part.

However, in the above-described technique, when the upper case and the lower case are loosened, the connection member and the connection portion may be separated, and the electrical contact of the connection portion may be exposed. When exposed electrical contacts are subjected to external factors (e.g., exposure to water or a humid environment), product failure may result. In addition, when the contact between the connection member and the connection portion is not tight, the connection portion is difficult to be kept stable, and the sensor may be caused to fall off.

In this case, the connector is capable of preventing the electrical contact of the connection portion from being exposed (i.e., even if the connection portion is maintained in a sealed state), and reducing adverse effects (e.g., failure or contamination of the connection portion) of the electrical contact of the connection portion due to contact with the external environment when the first housing and the second housing are loosened or separated. In addition, the fixing piece can stably keep the connecting body and the connecting part in the containing part, the loosening condition of the connecting body and the connecting part can be reduced, meanwhile, the connecting body and the connecting part can be more tightly connected, the condition that the electric contact is exposed can be further reduced, and the sealing performance of the connecting part of the sensor can be improved.

In some examples, the location of the first through hole 12 at the base plate 11 may match the location of the implanted portion 31 of the sensor 30. In some examples, the location of the first through hole 12 at the base plate 11 may overlap with the location of the implanted portion 31 of the sensor 30.

In some examples, the implanted portion 31 may extend outwardly along the first through hole 12. In this case, when the monitoring device 1 or the first housing 10 is applied to the body surface of the host 6, the implanted portion 31 of the sensor 30 can be placed subcutaneously in the host 6.

In some examples, the implanted portion 31 may include a sensing layer that may be configured to react with the analyte to obtain analyte information.

In some examples, referring to fig. 3B, the first housing 10 may include a first sidewall 13. The first sidewall 13 may be connected with the bottom plate 11. In some examples, the first sidewall 13 may be configured to extend in a direction away from the host 6.

In some examples, the first housing 10 may include a snap groove 14 (see fig. 3A and 3B), and the snap groove 14 may be provided at the first sidewall 13. In some examples, the snap groove 14 may be a square hole, a round hole, or an oval hole.

In some examples, the first case 10 may include a pressing portion 15 (see fig. 3A and 3B), and the pressing portion 15 may be provided to the first sidewall 13. In some examples, the pressing portion 15 may be configured to couple or decouple the first housing 10 from the second housing 20. Specifically, the pressing portion 15 may be configured such that the first housing 10 may be coupled to or decoupled from the second housing 20 when an action is applied to the pressing portion 15.

In some examples, the second housing 20 may include a second sidewall 21 (see fig. 3B) that mates with the first sidewall 13. In particular, the first sidewall 13 may be wholly or partially coupled with the second sidewall 21 to combine the first case 10 with the second case 20.

In some examples, referring to fig. 3B, the second housing 20 may include a first edge protrusion 22 and a second edge protrusion 23. The first and second edge protrusions 22 and 23 may be provided to the second sidewall 21.

In some examples, the first edge projection 22 may be configured to engage with the engagement slot 14. In some examples, the first edge projection 22 may be configured to engage the snap groove 14 by being placed into the snap groove 14. Thereby, the first casing 10 and the second casing 20 can be coupled to each other.

In some examples, the second edge protrusion 23 may be configured to be combined with the pressing part 15. In some examples, the pressing portion 15 may include a first end 150 configured to engage with the second edge protrusion 23 (see fig. 3B). The end surface of the first end 150 may be conformed to the shape of the second edge projection 23.

In some examples, the pressing portion 15 may include a second end 151, and the second end 151 may be configured to control a combined state of the first end 150 and the second edge protrusion 23. In some examples, the coupled state may include a first state for characterizing the second edge projection 23 being engaged with the first end 150 and a second state for characterizing the second edge projection 23 being loose from the first end 150.

In some examples, the combined state may be changed by applying an action to the second end 151 of the pressing part 15, that is, the first state and the second state may be converted to each other by applying an action to the second end 151 of the pressing part 15.

In some examples, the second housing 20 may include a circuit structure. In some examples, the second housing 20 may include a circuit structure electrically connected to the sensor 30. In some examples, the circuit structure may include an electronic module that may be configured to process the electrical signals of the sensor 30 that are used to characterize the analyte information. In some examples, the electronic module may be configured to send analyte information to the intelligent terminal of host 6. In this case, the host 6 can be facilitated to acquire own analyte information, so that own physiological parameters can be monitored in real time.

In some examples, the circuit structure may include a power supply module. The power module may be configured to provide power to the monitoring device 1 to enable the monitoring device 1 to function properly. In some examples, the power module may be a rechargeable battery.

In some examples, the second housing 20 may be configured to abut the fixture 50 when combined with the first housing 10. In this case, the second housing 20 can exert an action on the fixing member 50 when combined with the first housing 10, so that the fixing member 50 can be further pressed against the connection body 40, and thus the stability of the connection body 40 and the connection portion 32 can be improved. Meanwhile, since the connection of the connection body 40 and the connection portion 32 is tighter, the sealability of the connection portion 32 can be improved.

In some examples, referring to fig. 4A and 4B, the first housing 10 may have a receiving portion 16. The receiving portion 16 may be configured to receive the connection body 40 and the connection portion 32.

In some examples, referring to fig. 4B, the sensor 30 may include a connection portion 32. The connection portion 32 may be connected with the implantation portion 31.

In some examples, the connection portion 32 may have electrical contacts. In some examples, the connection portion 32 may have at least one electrical contact. For example, the connection portion 32 may have one, two or three electrical contacts.

In some examples, the sensor 30 may be electrically connected to the connector 40 via electrical contacts. In other words, in some examples, electrical signals collected by sensor 30 that are used to characterize analyte information may be transmitted to the circuit structure through connector 40.

In some examples, the connecting portion 32 may match the inner contour of the receptacle 16. In some examples, the connecting body 40 may match the inner contour of the receiving portion 16.

In some examples, the connecting portion 32 and the connecting body 40 may match the inner profile of the receptacle 16. In some examples, mating may mean that the outer perimeter of the connecting portion 32 and the connecting body 40 may conform to the inner contour of the receiving portion 16. In this case, the occurrence of loosening of the connecting body 40 and the connecting portion 32 in the accommodating portion 16 can be reduced, and the stability of the connecting body 40 and the connecting portion 32 can be improved.

In some examples, the inner profile of the side wall of the fixture 50 may match the outer profile of the receptacle 16. In this case, the fixing member 50 and the accommodating portion 16 can be more tightly combined, and at the same time, errors in assembly can be reduced, so that convenience in assembling the fixing member 50 and the accommodating portion 16 can be improved.

In some examples, the connector 40 may include at least one conductive channel within which a conductive material may be disposed. In other words, the conductive material may be used to fill into the conductive channels.

In some examples, the second housing 20 may include a circuit structure electrically connected with the connection body 40. Specifically, in some examples, the second housing 20 may include circuit structures that electrically connect with conductive material within the conductive channels of the connector 40. In some examples, one end of the conductive via may be in contact with the connection portion 32 and the other end of the conductive via may be in contact with the circuit structure. Thereby, the connection portion 32 of the sensor 30 can be electrically connected to the circuit structure of the second housing 20 based on the connection body 40.

In some examples, the connector 40 may have an electrical conductor 41. In some examples, electrical conductor 41 may be located within a conductive channel. In some examples, the electrical conductor 41 may have conductive properties. In some examples, the connector 40 may have at least one electrical conductor 41.

In some examples, the connector 40 may have an electrical conductor 41 aligned with the electrical contact. In some examples, the connector 40 may have the same number of electrical conductors 41 aligned with and as the electrical contacts. For example, when the number of electrical contacts of the connection portion 32 is 3, the connection body 40 may have 3 conductors 41. In some examples, one end of the electrical conductor 41 may be connected to an electrical contact and the other end of the electrical conductor 41 may be connected to a circuit structure. Specifically, one end of each of the electrical conductors 41 may be connected with the aligned electrical contacts, and the other end of each of the electrical conductors 41 may be connected with the circuit structure of the second housing 20. In this case, since the sensor 30 generally transmits an electric signal through the electric contacts, by providing the same number of electric conductors 41 aligned with the electric contacts, the electric signal of each of the electric contacts in the sensor 30 can be transmitted to the circuit structure via the corresponding electric conductor 41, whereby the unstable current can be reduced, and further the reliability and stability of the electric connection of the sensor 30 and the circuit structure can be improved.

In some examples, referring to fig. 4B, the connector 40 may include an inner lumen 42. In some examples, the conductive pathway may be disposed in the interior cavity 42. In some examples, electrical conductor 41 may be disposed in lumen 42.

In some examples, the connector 40 may include a connection opening 43 (see fig. 4B). The connection opening 43 may be configured to place the connection body 40 in an open state or a closed state. In some examples, the sensor 30 may be placed in the lumen 42 of the connector 40. In some examples, the connection portion 32 of the sensor 30 may be placed in the connection opening 43 of the connection body 40. Specifically, the connecting portion 32 of the sensor 30 may be placed in the lumen 42 of the connecting body 40 through the connecting opening 43 when the connecting body 40 is in the open state, and the connecting body 40 may fully receive the connecting portion 32 in the lumen 42 when the connecting body 40 is in the closed state.

In some examples, the connector 40 may include a connection upper portion 44 and a connection lower portion 45 (see fig. 5A and 5B). The connection upper portion 44 and the connection lower portion 45 may be formed based on the connection opening 43.

In some examples, referring to fig. 5A, the connector 40 may include an inner cavity 42 and at least one pivot 46. The pivot 46 may be used to control the opening or closing of the connector 40. That is, the pivot 46 may be used to control the connection body 40 to be in an open state or a closed state. In some examples, the connector 40 may be configured to receive the electrical conductor 41 to the lumen 42 in the expanded state. In this case, the opening of the connector 40 can be controlled to facilitate the operation of the conductor 41 (e.g., the placement or replacement of the conductor 41, etc.), and at the same time, the closing of the connector 40 can be controlled to make the conductor 41 more stable after being placed in the cavity 42 of the connector 40.

In some examples, the pivot 46 may be disposed on both sides of the connection opening 43. In other words, the pivot portion 46 may be connected to the connection upper portion 44 and the connection lower portion 45, respectively. In this case, the connection upper portion 44 and the connection lower portion 45 can be controlled to approach or separate along the pivot portion 46, so that the connection body 40 can be controlled to be in an open state or a closed state.

In some examples, the connector 40 may include a plurality of pivot portions 46.

In some examples, the conductive path may be located at the connection upper portion 44.

In some examples, the connector 40 may be configured to receive the electrical conductor 41 to the connection upper 44 in the expanded state. In some examples, the connection upper 44 may include a first face in contact with the connection portion 32 of the sensor 30, and a second face in contact with the circuit structure. In this case, one end of the conductive body 41 can be electrically connected to the connection portion 32 of the sensor 30 based on the first face, while the other end of the conductive body 41 can be electrically connected to the circuit structure based on the second face, whereby the electric signal of the sensor 30 can be transmitted to the circuit structure.

In some examples, the connection lower portion 45 may include a third face that contacts the connection portion 32 of the sensor 30. In some examples, the first and third faces may be configured to cover and compress the connection portion 32 of the sensor 30 when the connection body 40 is in the closed state. This can improve the sealing property between the connecting body 40 and the connecting portion 32.

In some examples, the connector 40 may be made of a polymeric material. In some examples, the connector 40 may be made of silicone rubber. In this case, since the silicone rubber has elasticity, the connection portion 32 can be better wrapped based on elastic deformation, whereby the sealability of the connection body 40 with the connection portion 32 can be further improved.

In some examples, the connector 40 may include a pair of tab structures 47 (see fig. 5A). In some examples, the sheet structure 47 may include a first sheet 470 and a second sheet 471 that are disposed opposite one another. In some examples, the tab structure 47 may be disposed along both sides of the connection opening 43. In other words, the first tab 470 may be disposed at the connection upper portion 44 and the second tab 471 may be disposed at the connection lower portion 45. In some examples, the first tab 470 may abut the second tab 471 when the connector 40 is in the closed state.

In some examples, the connector 40 may have at least one pair of tab structures 47 disposed opposite each other. The tab structure 47 may have a second through hole 472. In some examples, the receptacle 16 may have a post 160 (see fig. 4B) extending through the second through hole 472 to connect the tab structure 47. In this case, the column 160 is connected to the sheet structure 47 through the second through hole 472, so that the connecting body 40 can be fixedly connected to the accommodating portion 16, and the stability of the connecting body 40 in the accommodating portion 16 can be improved.

In some examples, the diameter of the second through hole 472 may match the diameter of the bottom surface of the column 160. In some examples, "matching" may mean that the diameter of the second through hole 472 is not greater than/less than or equal to the diameter of the bottom surface of the column 160.

In some examples, the connector 40 may have a flange portion 48 (see fig. 5A). Specifically, the end surface of the connecting body 40 to which the fixing member 50 is coupled may have a flange portion 48. In some examples, flange portion 48 may be resilient. In this case, when the connecting body 40 is coupled with the fixing member 50, the fixing member 50 presses the flange portion 48 to deform the flange portion 48, so that a greater pressure can be applied to the coupled portion, thereby making the coupling tighter. In addition, the flange 48 can be deformed to fill the gap formed during bonding, and the bonding tightness can be further improved.

In some examples, the end surface of the connecting body 40 that is coupled to the securing member 50 may refer to the second surface of the connecting upper portion 44. That is, the flange portion 48 may be provided at the second face of the connection upper portion 44. In some examples, the second face may be extended in a direction toward the circuit structure to form the flange portion 48.

In some examples, the securing member 50 may be configured to secure the connecting body 40 and the connecting portion 32 to the receptacle 16.

In some examples, referring to fig. 6, the fixture 50 may have a hollowed-out structure 51. Specifically, the upper end of the fixing member 50 may have a hollowed-out structure 51. In some examples, an upper end of the mount 50 may abut the connector 40. Specifically, the upper end of the fixing member 50 may abut against the second face of the connection upper portion 44. In some examples, the electrical conductor 41 may be at least partially exposed through the hollowed-out structure 51 to electrically connect with the circuit structure. In this case, the conductor 41 in the connector 40 can be brought into contact with the circuit structure more sufficiently without affecting the fixing effect of the fixing member 50 on the connector 40.

In some examples, the conductive material within the conductive via may also be electrically connected to the circuit structure through the hollowed-out structure 51.

In a further example, the securing member 50 may have a snap groove 52. In some examples, the snap groove 52 may be configured to snap the fastener 50 with the receptacle 16. In some examples, the mount 50 may have at least one snap groove 52.

In some examples, with continued reference to fig. 4B, the receptacle 16 may have at least one snap projection 161. For example, the receiving portion 16 may have 1, 2, or 3 catching protrusions 161. In some examples, referring to fig. 6, the side walls of the mount 50 may have snap grooves 52 that mate with snap protrusions 161. In some examples, the snap groove 52 may snap with the snap projection 161 to snap the fastener 50 and the receptacle 16. In this case, the fixing member 50 can be more tightly coupled to the receiving portion 16, so that the stability of the connection body 40 and the connection portion 32 provided in the receiving portion 16 can be improved.

In some examples, the number of snap grooves 52 that mate with the snap projections 161 may mean that the number of snap grooves 52 is the same as the number of snap projections 161. For example, when the number of the catching protrusions 161 is 3, the number of the catching grooves 52 may be 3.

In some examples, referring to fig. 6, the mount 50 may include a first block 53 and a second block 54. In some examples, the first block 53 and the second block 54 may be disposed opposite an inner wall of the mount 50. In some examples, the first and second blocks 53, 54 may be configured to abut the receptacle 16. This can further improve the stability of the connection between the holder 50 and the housing 16.

In some examples, referring to fig. 6, the mount 50 may include a notch 55.

In some examples, the mount 50 may include at least one notched portion 55. For example, the fixture 50 may include 1, 2, or 3 notches 55. In some examples, the notch 55 may be located in a sidewall of the mount 50. In some examples, the notch 55 may be located at a ridge of a sidewall of the mount 50. That is, the notch 55 may be located at the junction of each face of the side wall of the mount 50. In this case, by providing the notched portion 55, the peripheral edge connection (i.e., the side wall) of the fixing member 50 can be broken, and the side wall of the fixing member 50 can be elastically deformed outward when the fixing member 50 is assembled, thereby facilitating the assembly of the fixing member 50 with the accommodating portion 16.

In the monitoring device 1 according to the present disclosure, the connection portion 32 of the sensor 30 is electrically connected to the circuit structure of the second housing 20 through the connection body 40, and the fixing member 50 fixes the connection body 40 and the connection portion 32 to the accommodation portion 16 of the first housing 10. In this case, the connector 40 can prevent the electrical contact of the connection portion 32 from being exposed (i.e., even if the connection portion 32 is kept in a sealed state), and can reduce adverse effects (e.g., failure or contamination of the connection portion 32) of the electrical contact of the connection portion 32 due to contact with the external environment when the first housing 10 and the second housing 20 are loosened or separated. In addition, the fixing member 50 can stably hold the connecting body 40 and the connecting portion 32 in the accommodating portion 16, and can reduce the loosening of the connecting body 40 and the connecting portion 32, and at the same time, can make the connection between the connecting body 40 and the connecting portion 32 tighter, and can further reduce the exposure of the electrical contacts, and can further improve the sealability of the connecting portion 32 of the sensor 30.

According to the present disclosure, it is possible to provide the monitoring device 1 that improves the sealability and stability of the sensor 30.

While the disclosure has been described in detail in connection with the drawings and examples, it is to be understood that the foregoing description is not intended to limit the disclosure in any way. Modifications and variations of the present disclosure may be made as desired by those skilled in the art without departing from the true spirit and scope of the disclosure, and such modifications and variations fall within the scope of the disclosure.
