Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of medical equipment, and specifically relates to an implantable device for an analyte sensor. Background Art
[0002] Detecting various analytes in an individual is essential for monitoring their health status. Deviations from normal analyte levels can often indicate underlying physiological conditions, such as metabolic conditions, diseases, etc. Regular ex vivo analyte monitoring using extracted body fluids is sufficient to observe the physiological conditions of many individuals. However, due to the limited number of test values, ex vivo analyte monitoring may cause irreversible harm to patients by missing the best treatment opportunity due to the lack of key measurement data. In addition, for individuals with severe analyte disorders and / or rapid fluctuations in analyte levels, body fluids need to be drawn more frequently for monitoring, which will cause inconvenience and pain to patients.
[0003] In many cases, subcutaneous, interstitial or skin analyte sensors can provide sufficient measurement accuracy while minimizing user discomfort. Continuous analyte monitoring using an implanted analyte monitoring sensor is an ideal monitoring method. Typically, an implant device is used to implant the analyte monitoring sensor into an individual. The sensor reacts with the body fluid of the implanted person to generate an electrical signal. The processing unit converts the electrical signal into data that can characterize the analyte concentration and transmits it to a display device for display, thereby achieving continuous monitoring of the analyte concentration.
[0004] Typically, an implant device is used to insert the sensor into the user's body. The puncture needle in the implant device engages with the sensor and brings the sensor under the user's skin. After the sensor is implanted, the puncture needle is removed from the user's body while the sensor remains in the user's body. Current products have technical problems such as complex sterilization processes and numerous user operation steps, which also increase the probability of sensor implantation failure due to improper user operation.

[0044] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.
[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present application.

[0048] In the present application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0049] like Figure 1, Figure 2 As shown, an implant device of an analyte sensor 724 includes a shell 1, which is provided with a accommodating cavity 11; a monitoring unit 7, which is arranged in the accommodating cavity 11, and the monitoring unit 7 includes a first module 71 and a second module 72, and the first module 71 and the second module 72 are arranged at an interval; and a driving unit 4, which is arranged in the accommodating cavity 11, and the driving unit 4 is configured to drive the monitoring unit 7 to move along a first direction; wherein, in the process of the driving unit 4 driving the monitoring unit 7 to move along the first direction, at least one of the first module 71 and the second module 72 moves in a direction close to the other so that the first module 71 and the second module 72 are assembled.
[0050] Preferably, the first direction is the axial direction of the housing 1 .
[0051] In the present application, the first module 71 and the second module 72 of the monitoring unit 7 are fixed at intervals in the accommodating cavity 11, and the two are independently arranged. Therefore, two different sterilization methods can be used to sterilize the two modules respectively, or an isolation barrier can be installed between the two to achieve local sterilization. Under the premise of effectively avoiding damage to the electronic unit caused by radiation sterilization, the complexity of the sterilization process is reduced, thereby simplifying the production process.
[0052] For example, in one embodiment, the first module 71 and the second module 72 are spaced apart, and a radiation isolation piece is provided between the two, so that the chambers where the first module 71 and the second module 72 are located are isolated from each other, so that local sterilization can be achieved, and when the sensor is sterilized by radiation sterilization, damage to the electronic unit caused by radiation is avoided. Preferably, the isolation piece should be made of a material that can block radiation and gas.
[0053] In addition, the monitoring unit 7 has been assembled with the housing 1 before leaving the factory, and the user does not need to perform additional assembly steps after receiving the product, which reduces the steps that the user needs to operate, thereby reducing the difficulty of use and improving the convenience of use. Further, after the implantation action is triggered, the first module 71 and the second module 72 are assembled under the drive of the drive unit 4, and the user does not need to perform additional operations, which greatly simplifies the operation steps during the user's use, reduces the difficulty of product operation, reduces the user's learning cost, and improves the user's experience.
[0054] After the implantation action is triggered, the first module 71 and the second module 72 can be automatically assembled under the drive of the driving unit 4. Similarly, the user does not need to perform additional operations. Only one trigger operation needs to be performed. During the movement of the driving unit 4 along the first direction, the first module 71 and the second module 72 are assembled first, and then the monitoring unit 7 moves as a whole along the first direction to implant the sensor 724 under the host's skin. The attachment 73 on the bottom surface of the monitoring unit 7 is bonded and fixed to the user's skin, so that the user can wear it with him. In this way, a single trigger operation is achieved, and multiple steps are automatically completed. The operation steps of the user during the implantation process are greatly simplified, the difficulty of product operation is reduced, and the user's learning cost is reduced. At the same time, the duration of the entire implantation stage is also shortened, which helps to reduce the fear of the user while waiting for implantation.
[0055] For example, the sensor 724 can be set in the first module 71, and the transmitter can be set in the second module 72. After the two modules are sterilized in different ways (for example, the first module 71 is sterilized by radiation sterilization, and the second module 72 is sterilized by gas sterilization), the first module 71 and the second module 72 are fixed inside the accommodating cavity 11 respectively, and then subsequently packaged and shipped.
[0056] like Figure 2 As shown, an implantation port 13 is provided at one end of the housing 1 along the first direction. When in use, the user places the end with the implantation port 13 against the skin surface so that the skin surface covers the implantation port 13, and then triggers the implantation device to complete the implantation of the sensor 724.
[0057] In the prior art, in some monitoring units, the sensor module and the transmitter module are stacked up and down, that is, the projections of the two in the up and down directions overlap, which increases the overall height (thickness) of the monitoring unit housing and produces obvious bulges in the appearance. As a result, after the monitoring unit is pasted and fixed on the user's skin surface, it is very easy to rub against the user's clothes, especially in the abdomen, upper arms and other parts. In addition, the surface area of the attachment on the bottom surface of the monitoring unit is also small, which directly affects the contact area between the attachment and the skin surface. On the one hand, it makes the pasting stability poor, and at the same time, it cannot fit the curvature of the skin surface well, so it is easy to fall off. On the other hand, the pressure distribution of the monitoring unit on the skin surface is relatively concentrated, and the local pressure is relatively large, which is easy to cause discomfort when worn for a long time.
[0058] The present application does not limit the assembly method of the first module 71 and the second module 72. In one embodiment, Figures 2 to 5As shown, during the assembly process of the first module 71 and the second module 72, the second module 72 remains in position, and the first module 71 moves toward the direction close to the first module 71 to complete the assembly of the two. Alternatively, the first module 71 remains stationary, and the second module 72 moves toward the direction close to the second module 72 to complete the assembly. Alternatively, the first module 71 and the second module 72 each move toward the direction close to each other to complete the assembly.
[0059] As a preferred implementation of the present application, Figure 5 , Figure 6 As shown, the projections of the first module 71 and the second module 72 along the first direction have no overlap.
[0060] It should be noted that, in the present application, the monitoring unit 7 has an initial state in which the first module 71 and the second module 72 are arranged separately, and an assembled state in which the first module 71 and the second module 72 are assembled. Regardless of the initial state or the assembled state, the projections of the first module 71 and the second module 72 along the first direction do not overlap. Figure 5 , Figure 6 The first module 71 and the second module 72 are in an unassembled state.
[0061] After the first module 71 and the second module 72 are assembled, the overall height of the monitoring unit 7 is directly and effectively reduced, and the probability of friction with clothing after wearing is reduced. At the same time, the surface area of the bottom of the monitoring unit 7 is increased, and the distribution of colloids on the surface of the attachment 73 is optimized to resist shear force, so that the anti-twist performance of the monitoring unit 7 is improved, and it can be more firmly attached to the skin surface and better fit the curvature of the skin surface, thereby improving the adhesion stability of the monitoring unit 7 to the skin surface.
[0062] In addition, the pressure distribution of the monitoring unit 7 on the skin surface is more uniform, which can reduce local pressure and is particularly suitable for long-term wearing, thereby improving wearing comfort.
[0063] Furthermore, the electronic components in the module will generate a certain amount of heat during operation, and the two modules have no overlap, which is more conducive to heat dissipation, thereby avoiding excessive temperature rise in the monitoring unit 7 locally and causing discomfort to the user.
[0064] It should be noted that the present application does not limit the assembly direction of the first module 71 and the second module 72. In a preferred embodiment, Figures 2 to 7 As shown, the first module 71 and the second module 72 are spaced apart along the second direction, and at least one of the first module 71 and the second module 72 moves along the second direction to complete the assembly of the first module 71 and the second module 72, and the second direction is perpendicular to the first direction.
[0065] Preferably, the second direction is a direction perpendicular to the axis of the housing 1 .
[0066] The first module 71 and the second module 72 are assembled in a direction perpendicular to the first direction. On the one hand, it can avoid that the two modules will have a large collision and extrusion force in the first direction under the driving force of the driving unit 4 in the first direction, thereby generating a large vibration or shaking, and avoid the hidden danger of unstable structural connection and electrical connection due to severe collision. On the other hand, after the first module 71 and the second module 72 are assembled in the second direction, it is more helpful to achieve non-overlapping projections of the two in the first direction.
[0067] In a preferred embodiment of this embodiment, Figure 2 As shown, the monitoring unit 7 has an initial state and an assembled state. In the initial state, the first module 71 and the second module 72 are spaced apart. In the assembled state, the first module 71 and the second module 72 are assembled. In the initial state, the first module 71 and the second module 72 are at the same height in the first direction.
[0068] In the initial state, the first module 71 and the second module 72 are arranged at the same horizontal height, so that the assembly of the two along the second direction is simpler and more reliable. After the implantation action is triggered, the first module 71 and the second module 72 are assembled in a direction perpendicular to the axis of the shell 1, and then move together along the first direction to perform the implantation action.
[0069] It should be noted that the first module 71 and / or the second module 72 can be assembled by moving in a single direction, the second direction, as in the above-mentioned embodiment. They can also be assembled by moving in other directions, as long as there is a displacement in the second direction. For example, in another embodiment, during the assembly process, the first module 71 and / or the second module 72 have a displacement in both the first direction and the second direction, that is, they move in an inclined direction so as to be close to each other to complete the assembly.
[0070] In a specific example, the first module 71 and the second module 72 both move in the first direction and also move in the second direction toward the central axis of the housing 1 , so that the two are assembled with an inclined motion trajectory.
[0071] In another specific example, in the initial state, the first module 71 and the second module 72 are at different heights in the first direction, that is, they are at different horizontal heights. For example, the second module 72 is higher than the first module 71. During the assembly process, the second module 72 moves along the first direction while also moving along the second direction toward the central axis of the housing 1, thereby completing the assembly with the first module 71 below.
[0072] Of course, in other embodiments, the first module 71 and the second module 72 may also be assembled along the first direction, which is not limited here.
[0073] Preferably, the first module 71 includes a data transmission unit, the second module 72 includes a data acquisition unit, and the first module 71 moves toward the direction close to the second module 72 to complete the assembly of the data transmission unit and the data acquisition unit.
[0074] It can be understood that the data acquisition unit is the sensor 724, the data transmission unit of the first module 71 is suitable for irradiation sterilization, and the data acquisition unit of the second module 72 is suitable for gas sterilization. After the two modules are sterilized in different ways, the first module 71 and the second module 72 are fixed inside the accommodating cavity 11 respectively, and then subsequently packaged and shipped. After the implantation action is triggered, the two are assembled to form a complete monitoring unit 7, so that they can work normally.
[0075] Meanwhile, the second module 72 is fixed with the puncture unit 5 , and the second module 72 remains stationary during the assembly process, thereby ensuring the position stability of the puncture unit 5 .
[0076] In one embodiment, the first module 71 also includes a data processing unit, wherein the data processing unit can be arranged inside the first module 71 or outside the first module 71, such as a mobile device such as a mobile phone, which is not limited here.
[0077] It should be noted that the present application does not limit the driving mode of the driving unit 4, and it can be manually driven, that is, the user manually drives the driving unit 4 to move along the first direction. Preferably, Figure 2 , Figure 3 , Figure 8 As shown, the driving unit 4 includes a booster spring 41 and a driving member 42. The booster spring 41 abuts between the inner wall of the housing 1 and the driving member 42. The power of the driving member 42 is provided by the booster spring 41. In the initial state, the driving member 42 is locked inside the housing 1. At this time, the booster spring 41 is in a compressed state. When the user triggers the unlocking, the booster spring 41 pushes the driving member 42 under its own elastic force, so that the driving member 42 moves along the first direction to perform the implantation action. This method not only realizes automatic implantation, but also uses the booster spring 41 to drive, and can better control the movement speed of the driving member 42, making it more uniform, and the movement direction is more stable, avoiding jamming during movement, thereby reducing shaking and alleviating the user's pain during implantation.
[0078] Furthermore, if Figure 2As shown, the inner wall of the housing 1 and / or the driving member 42 is provided with a limiting groove 12, and the end of the booster spring 41 is placed in the limiting groove 12. The limiting groove 12 can limit the end of the booster spring 41, so that the booster spring 41 always deforms along its own axial direction and provides a stable force along the first direction to the driving member 42. Specifically, as Figure 2 As shown, both the driving member 42 and the housing 1 are provided with limiting grooves 12 , so that both ends of the boosting spring 41 are located in the limiting grooves 12 .
[0079] The present application does not limit the method for driving the first module 71 and the second module 72 to complete the assembly. As an embodiment, the driving unit 4 includes a driving member 42, and the driving member 42 is provided with a driving inclined surface. During the movement of the first module 71 and / or the second module 72 along the first direction, the driving inclined surface can drive the first module 71 and / or the second module 72 to deviate in a direction close to each other.
[0080] It should be noted that the inclination direction of the driving inclined plane is different according to the relative position of the driving member 42 and the monitoring unit 7. For example, in one embodiment, the driving member 42 is located above the monitoring unit 7, and a driving inclined plane is provided on the lower side of the driving member 42, and the driving inclined plane is inclined from the first direction to gradually away from the central axis of the accommodating chamber 11.
[0081] When the driving member 42 moves in the first direction, the driving inclined surface contacts the first module 71 and / or the second module 72, so that the force in the first direction is converted into a force perpendicular to the first direction through the driving inclined surface, thereby pushing the first module 71 and / or the second module 72 closer to each other to complete the assembly. Preferably, the driving inclined surface contacts the outer side wall of the first module 71 and / or the second module 72 to push them in the direction close to the central axis of the housing 1.
[0082] Of course, in another embodiment, a slope structure inclined from the first direction gradually away from the central axis of the accommodating chamber 11 can be set in the first module 71 and / or the second module 72, and the slope structure can contact the driving member 42, so that the driving member 42 can also generate a lateral thrust thereon.
[0083] In another embodiment, the driving member 42 includes a pushing structure located on one lateral side of the monitoring unit 7, and a driving slope is provided on the pushing structure, and the driving slope is inclined from the first direction to gradually approach the central axis of the accommodating cavity 11, so as to push the first module 71 and / or the second module 72 toward the direction close to the central axis of the housing 1 while moving along the first direction. The pushing structure can be a pushing device such as a spring, and when the user triggers the implant device, the pushing structure is also triggered to form a pushing force on the first module 71 and / or the second module 72 to drive the two to assemble.
[0084] In the above-mentioned embodiments, the driving member 42 is in direct contact with the monitoring unit 7 and thus directly drives the monitoring unit 7 , which can improve the transmission efficiency and improve the movement smoothness and stability of the first module 71 and the second module 72 .
[0085] As another implementation mode of the present application, Figures 2 to 5 As shown, the driving unit 4 includes a driving member 42 and a transmission member 44. The transmission member 44 is arranged between the driving member 42 and the monitoring unit 7. The driving member 42 can drive the transmission member 44 to move to push the first module 71 and / or the second module 72 to achieve assembly between the two.
[0086] In this embodiment, the driving member 42 drives the first module 71 and / or the second module 72 through the transmission member 44 to achieve indirect drive. Specifically, in one embodiment, an inclined surface structure may be provided between the driving member 42 and / or the transmission member 44 so that the two are in contact through the inclined surface, thereby causing the driving force of the driving member 42 along the first direction to form a thrust perpendicular to the first direction on the transmission member 44, thereby causing the transmission member 44 to push the first module 71 and / or the second module 72 to move and complete assembly.
[0087] Preferably, if Figures 2 to 5 As shown, the implant device also includes a guide member 6, which is arranged inside the accommodating cavity 11. The guide member 6 and / or the transmission member 44 are provided with a guide slope 61 which is inclined from the first direction to gradually approach the central axis of the accommodating cavity 11. During the movement of the driving member 42 along the first direction, the guide slope 61 can drive the transmission member 44 to move to push the first module 71 and / or the second module 72 to offset in the direction close to each other.
[0088] Specifically, the driving member 42 can drive the transmission member 44 to move together. When the transmission member 44 moves along the first direction, it is guided by the guide slope 61 and moves in a direction perpendicular to the first direction, thereby pushing the first module 71 and / or the second module 72 to move.
[0089] Preferably, if Figures 3 to 5 As shown, the transmission member 44 is also provided with a matching inclined surface that matches with the guide inclined surface 61 .

The pushing portion 441 is located on one side of the outer periphery of the first module 71 and / or the second module 72, and at least partially surrounds the first module 71 and / or the second module 72, so as to increase the contact area between the transmission member 44 and the first module 71 and / or the second module 72, and apply a stable thrust thereto.

Preferably, the unlocking member 2 is a button, and the cross-sectional area of the unlocking member 2 is smaller than the cross-sectional area of the accommodating cavity 11, so that the end of the housing 1 also has a wall surface surrounding the outer periphery of the unlocking member 2, thereby realizing a miniaturized design of the unlocking member 2. Of course, the end of the housing 1 can also be completely opened to form an opening, so that the unlocking member 2 can be directly guided by the inner peripheral surface of the accommodating cavity 11 and move along the first direction.

At the same time, since the puncture unit 5 is fixed to the second module 72, during the assembly of the first module 71 and the second module 72, if the second module 72 moves, the puncture unit 5 can also move synchronously with it, thereby avoiding relative movement between the two and misalignment in the first direction, resulting in the puncture needle 53 and the through port being unable to be aligned and implanted.

[0110] Before the first module 71 and the second module 72 are assembled, the battery and the second module 72 are also separated, and the battery and the electronic components on the first module 71 are not electrically connected.

Thus, after the components are installed in the accommodating cavity 11, the housing 1 is sterilized as a whole, and after the sterilization is completed, the accommodating cavity 11 is sealed by the shielding member to form a sterile environment inside.
