Description

Sensor implantation device and method of use thereof

[0001] This application claims priority to the Chinese patent application No. 202410860527.5, filed on June 28, 2024, and entitled "Sensor implantation device and method of use thereof", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application belongs to the technical field of continuous analyte monitoring, and specifically relates to a sensor implantation device and a method of use thereof. BACKGROUND

[0003] CGM (continuous glucose monitoring device) is a technical means for continuously monitoring the glucose concentration of subcutaneous tissue fluid through a glucose sensor, and indirectly reflecting the blood glucose level. The CGM product tests blood glucose by having a sensor pin penetrate into the subcutaneous tissue, and through the bioenzyme on the sensor and the electrochemical reaction with the subcutaneous tissue fluid, an electrical signal is generated, and the electrical signal is converted into blood glucose data and provided to the user. Since the sensor pin needs to penetrate into the subcutaneous tissue, the CGM product needs to have a needle helper to help the sensor pin penetrate into the subcutaneous tissue.

[0004] The needle helper includes a housing, a core provided in the interior of the housing, a puncture needle provided on the core, a spring provided in the interior of the housing and acting on the core, and a tension spring provided on the core and acting on the puncture needle. When the unlocking mechanism on the housing is pressed, the core is released from the clamping cooperation with the housing, and then the core drives the puncture needle to move towards the needle helper position under the action of the spring, so that the sensor penetrates into the subcutaneous tissue. When the core moves to the needle helper position, the puncture needle moves to the needle withdrawal position under the action of the tension spring, so that the puncture needle withdraws from the subcutaneous tissue, and the sensor pin stays in the subcutaneous tissue, to complete the penetration of the sensor pin into the subcutaneous tissue. In the related art, the needle helper is a single-use product, thereby increasing the use cost of the user, and also causing waste of resources. SUMMARY

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0056] Referring to FIGS. 1-12, a sensor implanting device is disclosed, comprising a housing 1, a connecting member 2, a puncture assembly 3, and a driving assembly 4, wherein the housing 1 comprises a mounting space; the connecting member 2 is arranged in the mounting space and is configured to be movable relative to the housing 1; the puncture assembly 3 is arranged in the mounting space and is detachably connected with the connecting member 2; the driving assembly 4 is used to drive the connecting member 2 to move in a first direction to partially pierce the puncture assembly 3 into the subcutaneous tissue of a living body, the puncture assembly 3 is configured to be movable in the first direction to be separated from the connecting member 2, and is configured to be movable in a second direction to be mounted to the connecting member 2, the second direction being opposite to the first direction.

[0057] It can be understood that the housing 1 has a mounting space inside, and the bottom of the housing 1 has a implantation opening communicating with the mounting space. The first direction in the present application is relative to the implantation opening. Specifically, the first direction is the direction of the inside of the housing 1 along the axial direction close to the implantation opening, and the second direction is the direction of the inside of the housing 1 along the axial direction away from the implantation opening.

[0058] Since the puncture assembly 3 is detachably connected with the connecting piece 2, the used puncture assembly 3 can be removed from the connecting piece 2, and then a new puncture assembly 3 is installed on the connecting piece 2, so that the sensor implantation device can be used again after replacing the puncture assembly 3. The user only needs to purchase multiple puncture assemblies 3, which reduces the use cost of the user and avoids waste of resources, thereby achieving the effect of saving resources.

[0059] Moreover, since the driving assembly 4 drives the connecting piece 2 to move in the first direction to partially penetrate the puncture assembly 3 into the subcutaneous tissue, the puncture assembly 3 can move in the first direction to separate from the connecting piece 2, so that when the puncture assembly 3 is disassembled, only a force in the first direction needs to be applied to the puncture assembly 3, and the puncture assembly 3 can be installed in the connecting piece 2 in the second direction, which reduces the difficulty of the user in disassembling the puncture assembly 3, thereby improving the efficiency and convenience of the user in disassembling the puncture assembly 3, and improving the user experience.

[0060] In a preferred embodiment, referring to FIGS. 1-5, the driving assembly 4 includes a driving piece 42, which can be compressed during movement of the puncture assembly 3 in the second direction, so that the driving piece 42 can be charged at the same time as the puncture assembly 3 is installed, thereby avoiding the need for an additional operation step to charge the driving piece 42, thereby simplifying the operation steps required by the user when using the sensor implantation device, thereby reducing the operation difficulty of the user, thereby improving the use efficiency of the user and further improving the user experience.

[0061] The present application does not make specific limitations on the disassembly method of the puncture assembly 3. Preferably, the connecting piece 2 has a release position that can be separated from the puncture assembly 3, and the sensor implantation device further comprises a push rod 5 arranged in the mounting space, which is used to push the connecting piece 2 to the release position.

[0062] That is, when disassembling the puncture assembly 3, only a force in the first direction needs to be applied to the push rod 5.

[0063] Specifically, when the puncture assembly 3 is disassembled, a pushing force is applied to the push rod 5 in the first direction, so that the push rod 5 pushes the connecting piece 2 to move towards the release position, so that the connecting piece 2 is separated from the puncture assembly 3 in the release position, avoiding the user directly contacting the puncture assembly 3 for release, thereby avoiding the risk that the puncture assembly 3 may cause harm to the user, and further improving the user experience.

[0064] Further, referring to FIGS. 3, 6 and 7, the push rod 5 is provided with a limiting portion 51, the shell 1 is provided with a stop portion 111 and a avoiding portion 112, when the limiting portion 51 is in stop cooperation with the stop portion 111, the push rod 5 is prevented from moving in the first direction, and when the limiting portion 51 is in cooperation with the avoiding portion 112, the push rod 5 can move in the first direction to push the connecting piece 2 to the release position.

[0065] It can be understood that when the sensor implanting device is shipped, the limiting portion 51 is in cooperation with the avoiding portion 112, so that most of the area of the push rod 5 can be hidden inside the shell 1, thereby reducing the storage volume of the analyte online blood glucose monitoring device.

[0066] When the sensor implanting device is used to assist the sensor 34 to penetrate into the subcutaneous tissue, the push rod 5 is first pulled in the second direction, so that the push rod 5 drives the limiting portion 51 to move to a position capable of being in stop cooperation with the stop portion 111, and then the push rod 5 is rotated to make the limiting portion 51 stop cooperating with the stop portion 111, so that the stop cooperation between the limiting portion 51 and the stop portion 111 blocks the push rod 5 from moving in the first direction, thereby ensuring the smoothness of the sensor 34 penetrating into the subcutaneous tissue; when the puncture assembly 3 needs to be disassembled, the push rod 5 is rotated, so that the limiting portion 51 is released from the stop cooperation with the stop portion 111, and the limiting portion 51 cooperates with the avoiding portion 112, and then the push rod 5 is pressed towards the first direction, so that the push rod 5 pushes the connecting piece 2 towards the release position, so that the connecting piece 2 moves to the release position and releases the puncture assembly 3.

[0067] Preferably, referring to FIGS. 3, 6 and 7, the shell 1 is provided with a guide portion 11 with a ring-shaped cross section, the push rod 5 is arranged in the guide portion 11, the connecting piece 2 is located inside the guide portion 11, the limiting portion 51 is a strip-shaped structure arranged on the outer circumferential surface of the push rod 5 and extending along the axial direction of the push rod 5, and the inside of the guide portion 11 is provided with a plurality of arc-shaped structures along the circumferential direction thereof, so that the arc-shaped structures form the stop portion 111, and the space between the arc-shaped structures forms the avoiding portion 112, so that when the limiting portion 51 is switched from the stop cooperation with the stop portion 111 to the cooperation with the avoiding portion 112, only the push rod 5 needs to be rotated, thereby achieving the effect that the cooperation state of the limiting portion 51 is convenient to switch.

[0068] In other embodiments, the push rod 5 can also be removed, that is, when the puncture assembly 3 is disassembled, the user needs to exert a force on the puncture assembly 3 in the first direction to drive the connecting member 2 to the release position to release the puncture assembly 3.

[0069] Further, referring to FIGS. 1-5, the push rod 5 is hollow inside, and the drive assembly 4 further comprises a pulling member 43 acting on the connecting member 2, both ends of the pulling member 43 are connected to the top of the push rod 5 and the connecting member 2 respectively, and when the puncture assembly 3 moves in the first direction to make the sensor 34 penetrate into the subcutaneous tissue, the limiting portion 51 and the stop portion 111 are in the stop state, so that after the puncture assembly 3 penetrates into the subcutaneous tissue, the pulling member 43 is in the deformed state, so that after the implantation action is completed, the connecting member 2 can move in the second direction under the action of the pulling member 43 to realize the needle withdrawal action.

[0070] The present application does not make specific limitations on the way the sleeve 41 follows the puncture assembly 3 to move in the second direction when the puncture assembly 3 is installed in the second direction, which can adopt any one of the following embodiments:

[0071] Embodiment one, in this embodiment, referring to FIG. 1, the drive assembly 4 comprises a limiting block 44 capable of reciprocating in a third direction perpendicular to the first direction, an elastic member 45 for applying force to the limiting block 44, and a switching block 12 arranged in the installation space, the elastic member 45 is used to apply a force to the limiting block 44 towards the puncture assembly 3 to prevent the puncture assembly 3 from moving in the second direction, and the switching block 12 can apply a force to the limiting block 44 away from the puncture assembly 3 to make the limiting block 44 overcome the force of the elastic member 45 and separate from the puncture assembly 3.

[0072] It can be understood that the drive assembly 4 further comprises a sleeve 41 and a driving member 42 acting on the sleeve 41, the driving member 42 is used to drive the sleeve 41 to move in the first direction, and the limiting block 44 is connected to the sleeve 41 in the radial direction of the sleeve 41.

[0073] Specifically, when the puncture assembly 3 is installed along the second direction, the puncture assembly 3 is in abutment with the limiting block 44, so that the puncture assembly 3 drives the limiting block 44 to move along the second direction, and then the limiting block 44 is separated from the switching block 12, and the limiting block 44 moves towards the puncture assembly 3 under the action of the elastic element 45, and then the limiting block 44 is connected to the puncture assembly 3, so that the driving element 42 is compressed along the second direction, so as to achieve the installation of the puncture assembly 3 and the force storage of the driving element 42; when the sensor implantation auxiliary sensor 34 is inserted into the subcutaneous tissue, the limiting block 44 moves along the first direction under the action of the driving element 42, so that the limiting block 44 drives the puncture assembly 3 to move along the first direction, and then the puncture assembly 3 and the sensor 34 are inserted into the subcutaneous tissue, and when the sensor 34 and the puncture assembly 3 are inserted into the subcutaneous tissue, the switching block 12 cooperates with the limiting block 44, so that the switching block 12 applies a force to the limiting block 44 away from the puncture assembly 3, so that the limiting block 44 is separated from the puncture assembly 3 by overcoming the force of the elastic element 45, so that the connecting element 2 can drive the puncture assembly 3 to move along the second direction, so as to realize the needle withdrawal action.

[0074] Preferably, referring to FIGS. 1-6, the bottom of the limiting block 44 is provided with a cooperation surface 441 capable of cooperating with the switching block 12, and the cooperation surface 441 is inclined, so that when the limiting block 44 cooperates with the switching block 12, the cooperation surface 441 is in contact with the switching block 12, and then the limiting block 44 moves away from the puncture assembly 3 under the action of the cooperation surface 441.

[0075] The structure of the elastic element 45 is not limited in the present application, and preferably, referring to FIGS. 1, 3, 4 and 5, the elastic element 45 is a spring, which can ensure the elastic driving effect of the elastic element 45 on the limiting block 44 and increase the stability of the limiting block 44 during movement. In other embodiments, the elastic element 45 can also be an elastic sheet, an elastic column or other structures capable of applying an elastic force to the limiting block 44.

[0076] Preferably, referring to FIGS. 1, 3, 8 and 9, the limiting block 44 is provided with a receiving cavity, and at least part of the elastic element 45 is located in the receiving cavity, so as to increase the connection stability of the elastic element 45 and the limiting block 44. The sleeve 41 is provided with a sliding groove 411 extending along a third direction perpendicular to the first direction, and the limiting block 44 is provided with a sliding block 442 slidingly connected in the sliding groove 411, so that when the limiting block 44 moves along the third direction, the sliding cooperation between the sliding block 442 and the sliding groove 411 can guide the limiting block 44, thereby increasing the stability of the reciprocating movement of the limiting block 44.

[0077] Further, referring to FIG. 3 and FIG. 10, the puncture assembly 3 comprises a needle seat 31, a needle body 32 mounted on the needle seat 31, and a sealing shell 33 connected with the needle seat 31, the sealing shell 33 is provided with an abutting portion 331 capable of abutting with the limiting block 44, during the process of installing the puncture assembly 3 on the connecting piece 2 along the second direction, the abutting portion 331 abuts with the limiting block 44 along the second direction.

[0078] It can be understood that the limiting block 44 can be insertedly matched with the needle seat 31, so that when the sleeve 41 moves along the first direction under the action of the driving piece 42, the sleeve 41 drives the limiting block 44 to move, so that the needle seat 31 moves along the first direction with the sleeve 41, thereby completing the implantation action; when the implantation action is completed, the switching block 12 is matched with the limiting block, so that the limiting block 44 is separated from the needle seat 31, so that the needle seat 31 can move in the second direction to realize the needle retraction.

[0079] Specifically, when the puncture assembly 3 is installed along the second direction, the abutting portion 331 abuts with the limiting block 44 along the second direction, and then the limiting block 44 moves along the second direction under the action of the abutting portion 331, so that the limiting block 44 gradually separates from the switching block 12, the limiting block 44 moves towards the direction close to the puncture assembly 3 under the action of the elastic piece 45, so that the limiting block 44 is inserted into the needle seat 31, and after the puncture assembly 3 is installed in place, the sealing shell 33 needs to be removed, so that the needle body 32 can be inserted into the subcutaneous tissue. By providing the abutting portion 331 on the sealing shell 33, when the puncture assembly 3 is installed along the second direction, the limiting block 44 moves along the second direction with the puncture assembly 3, so as to realize the force storage of the driving piece 42.

[0080] The structure of the abutting portion 331 is not limited in the present application, preferably, referring to FIG. 3 and FIG. 10, the abutting portion 331 is a tubular structure arranged outside the sealing shell 33, and a space for accommodating the guide portion 11 is formed between the sealing shell 33 and the tubular structure, so that when the puncture assembly 3 is installed, the abutting portion 331 can avoid the guide portion 11 to ensure the smoothness of the installation of the puncture assembly 3. In other embodiments, the abutting portion 331 can also be a strip-shaped structure arranged on the sealing shell 33 and extending upward along the axial direction of the sealing shell 33.

[0081] In the present embodiment, preferably, referring to FIG. 1 to FIG. 6, the shell 1 is provided with a guide portion 11, the connecting piece 2 comprises a connecting portion 21 and a clamping portion 22, the bottom of the guide portion 11 is provided with an avoiding slot 114, when the clamping portion 22 is out of position with the avoiding slot 114, the clamping portion 22 can clamp and fix the puncture assembly 3, and when the clamping portion 22 is opposite to the avoiding slot 114, the clamping portion 22 releases the puncture assembly 3.

[0082] It can be understood that the clamping portion 22 has elasticity, and then when the clamping portion 22 is misaligned with the avoiding groove 114, the clamping portion 22 is deformed under the action of the inner wall of the guide portion 11 to be able to clamp and fix the puncture assembly 3; and when the clamping portion 22 is opposite to the avoiding groove 114, the clamping portion 22 restores the deformation under the action of its own elasticity and deviates into the avoiding groove 114 to release the puncture assembly 3.

[0083] Specifically, when the puncture assembly 3 is installed, the puncture assembly 3 is first aligned with the connecting piece 2, and then a force in the second direction is applied to the puncture assembly 3, and then the puncture assembly 3 drives the connecting piece 2 to move in the second direction, so that the clamping portion 22 is misaligned with the avoiding groove 114, and at the same time the clamping portion 22 is deformed towards the inside of the guide portion 11 under the action of the cylinder wall of the guide portion 11, so that the clamping portion 22 clamps and fixes the puncture assembly 3; when the puncture assembly 3 is disassembled, the connecting piece 2 drives the puncture assembly 3 to move in the first direction, and then the clamping portion 22 moves to a position opposite to the avoiding groove 114, at this time the clamping portion 22 is deformed towards the outside of the guide portion 11 through the avoiding groove 114, so that the clamping portion 22 releases the puncture assembly 3, to realize the clamping and fixing and releasing functions of the connecting piece 2 to the puncture assembly 3.

[0088] Specifically, the connector 2 has a target position and a needle withdrawing position above the target position, when the connector 2 moves to the target position, the guide surface 231 cooperates with the guide rib 13, so that the driving part 23 deforms and releases the stop cooperation with the sleeve 41, so that the connector 2 can move in the second direction under the action of the pulling part 43 and move to the needle withdrawing position, to complete the needle withdrawing action.

[0089] Preferably, referring to FIG. 12, the side of the driving part 23 away from the center of the guide part 11 is pointed, so as to ensure that the driving part 23 can restore the deformation and stop cooperate with the sleeve 41 when moving to the accommodating groove 113.

[0092] Specifically, when the puncture assembly 3 is disassembled, the puncture assembly 3 is pulled in the first direction, and then the puncture assembly 3 drives the connecting piece 2 to move in the first direction, at this time, the clamping part 22 slides relative to the guide rib 13, and when the clamping part 22 moves to the position where the avoiding gap 131 is located, that is, the clamping part 22 is opposite to the avoiding gap 131, the clamping part 22 is offset into the avoiding gap 131 under the action of its own elasticity, so that the clamping part 22 releases the puncture assembly 3, to complete the disassembly of the puncture assembly 3; when the puncture assembly 3 is installed, the puncture assembly 3 is aligned with the connecting piece 2, and then the puncture assembly 3 is pushed in the second direction, and then the puncture assembly 3 drives the connecting piece 2 to move in the second direction, so that the clamping part 22 is gradually dislocated from the avoiding gap 131 and cooperates with the guide rib 13, so that the clamping part 22 is offset to the inside of the guide part 11 under the action of the guide rib 13 and clamped on the puncture assembly 3, to complete the installation of the puncture assembly 3, and then the clamping and releasing of the connecting piece 2 on the puncture assembly 3 are realized.
