Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.
[0050] Referring to Figures 1 to 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 so as 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 is opposite to the first direction.
[0051] It can be understood that the housing 1 has a mounting space inside, and the bottom of the housing 1 has an implantation port communicating with the mounting space. In the present application, the first direction is relative to the implantation port. Specifically, the first direction is the direction of the housing 1 inside along its axial direction close to the implantation port, and the second direction is the direction of the housing 1 inside along its axial direction away from the implantation port.
[0052] Since the puncture assembly 3 is detachably connected with the connecting member 2, the used puncture assembly 3 can be removed from the connecting member 2, and then a new puncture assembly 3 can be mounted on the connecting member 2, so that the sensor implanting device can be used again after replacing the puncture assembly 3. The user only needs to purchase multiple puncture assemblies 3, which reduces the user's use cost and avoids waste of resources, thereby achieving the effect of saving resources.
[0053] Moreover, since the driving assembly 4 drives the connecting member 2 to move in the first direction so as to partially pierce the puncture assembly 3 into the subcutaneous tissue, the puncture assembly 3 is movable in the first direction to be separated from the connecting member 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 mounted to the connecting member 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's use experience.
[0054] In a preferred embodiment, referring to Figures 1 to 5 , the driving assembly 4 comprises a driving member 42, the puncture assembly 3 is capable of compressing the driving member 42 during the movement in the second direction, and then the driving member 42 is capable of being charged while the puncture assembly 3 is installed, so as to avoid the situation that the driving member 42 needs to be charged by an additional operation step, so as to simplify the operation steps required by the user when using the sensor implanting device, thereby reducing the operation difficulty of the user, and then improving the use efficiency of the user and further improving the use experience of the user.
[0055] The application does not make specific limitation on the dismounting mode of the puncture assembly 3, preferably, the connecting member 2 has a release position capable of being separated from the puncture assembly 3, and the sensor implanting device further comprises a push rod 5 penetrating into the installation space, the push rod 5 is used for pushing the connecting member 2 to the release position.
[0056] That is to say, when the puncture assembly 3 is dismounted, only the force in the first direction needs to be applied to the push rod 5.
[0057] Specifically, when the puncture assembly 3 is dismounted, the push rod 5 is applied with the pushing force in the first direction, and then the push rod 5 pushes the connecting member 2 to move towards the release position, so that the connecting member 2 is separated from the puncture assembly 3 at 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 use experience of the user.
[0058] Further, referring to Figure 3 , Figure 6 and Figure 7 , the push rod 5 is provided with a limiting portion 51, the housing 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 cooperates with the avoiding portion 112, the push rod 5 is capable of moving in the first direction to push the connecting member 2 to the release position.
[0059] It can be understood that when the sensor implanting device is shipped, the limiting portion 51 is in cooperation with the avoiding portion 112, and then most of the region of the push rod 5 can be hidden inside the housing 1, so as to reduce the storage volume of the analyte online blood glucose monitoring device.
[0060] When the sensor implanting device is used to assist the sensor 34 to penetrate into the subcutaneous tissue, the push rod 5 is pulled along the second direction first, then the push rod 5 drives the limiting portion 51 to move to a position capable of being in the stop cooperation with the stop portion 111, 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 movement of the push rod 5 along the first direction, to ensure 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, then the limiting portion 51 is disengaged from the stop cooperation with the stop portion 111, and the limiting portion 51 cooperates with the avoiding portion 112, then the push rod 5 is pressed towards the first direction, so that the connecting member 2 is pushed to the release position, to make the connecting member 2 move to the release position and release the puncture assembly 3.
[0061] Preferably, referring to Figure 3 , Figure 6 and Figure 7 , the housing 1 is provided with a guide portion 11 in a ring shape in cross section, the push rod 5 is arranged in the guide portion 11, the connecting member 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, 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 state of being in the stop cooperation with the stop portion 111 to the state of cooperating with the avoiding portion 112, only the rotation of the push rod 5 is needed, to achieve the effect of facilitating the switching of the cooperation state of the limiting portion 51.
[0062] In other embodiments, the push rod 5 can also be cancelled, that is, when the puncture assembly 3 needs to be disassembled, the user needs to apply a force along the first direction to the puncture assembly 3, to make the puncture assembly 3 drive the connecting member 2 to move to the release position to release the puncture assembly 3.
[0063] Further, referring to Figures 1 to 5 , the push rod 5 is hollow inside, and the drive assembly 4 further includes 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 along the first direction to make the sensor 34 penetrate into the subcutaneous tissue, the limiting portion 51 is in the stop state with the stop portion 111, 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 implanting action is completed, the connecting member 2 can move along the second direction under the action of the pulling member 43 to realize the needle withdrawing action.
[0064] The application does not make specific limitation on the mode that the sleeve 41 follows the puncture assembly 3 to move along the second direction when the puncture assembly 3 is installed along the second direction, which can adopt any one of the following embodiments:
[0065] Implementation Method 1, in this implementation method, refer to Figure 1 The drive assembly 4 includes a limiting block 44 capable of reciprocating along 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 disposed in the installation space. The elastic member 45 is used to apply a force toward the puncture assembly 3 to the limiting block 44 to prevent the puncture assembly 3 from moving along the second direction. The switching block 12 is capable of applying a force away from the puncture assembly 3 to the limiting block 44 so that the limiting block 44 overcomes the force of the elastic member 45 and separates from the puncture assembly 3.
[0066] It is understood that the drive assembly 4 also includes a sleeve 41 and a drive member 42 acting on the sleeve 41. The drive member 42 is used to drive the sleeve 41 to move in a first direction, and the limiting block 44 is slidably connected to the sleeve 41 in the radial direction.
[0067] Specifically, when the puncture component 3 is installed along the second direction, the puncture component 3 cooperates with the limiting block 44 to stop it, so that the puncture component 3 drives the limiting block 44 to move along the second direction, thereby separating the limiting block 44 from the switching block 12. Under the action of the elastic member 45, the limiting block 44 moves towards the puncture component 3, thereby connecting the limiting block 44 to the puncture component 3, so that the driving member 42 is compressed along the second direction, so as to realize the installation of the puncture component 3 while storing force on the driving member 42; and when the sensor implantation auxiliary sensor 34 is inserted into the subcutaneous tissue, the limiting block 44 stops the movement of the limiting block 44. Under the action of the driving member 42, the block 44 moves along the first direction, so that the limiting block 44 drives the puncture assembly 3 to move along the first direction, thereby causing the puncture assembly 3 and the sensor 34 to pierce the subcutaneous tissue. When the sensor 34 and the puncture assembly 3 pierce the subcutaneous tissue, the switching block 12 cooperates with the limiting block 44, so that the switching block 12 applies a force away from the puncture assembly 3 to the limiting block 44, thereby causing the limiting block 44 to overcome the force of the elastic member 45 and separate from the puncture assembly 3, so that the connecting member 2 can drive the puncture assembly 3 to move along the second direction to realize the needle withdrawal action.
[0068] The better one is to refer to Figures 1 to 6 The bottom of the limiting block 44 is provided with a mating surface 441 that can cooperate with the switching block 12. The mating surface 441 is inclined so that when the limiting block 44 cooperates with the switching block 12, the mating surface 441 contacts the switching block 12, thereby causing the limiting block 44 to move away from the puncture component 3 under the action of the mating surface 441.
[0069] This application does not specifically limit the structure of the elastic element 45; preferably, refer to... Figure 1 , Figure 3 , Figure 4 and Figure 5In other embodiments, the elastic member 45 can also be an elastic sheet, an elastic column, or other structure capable of exerting elastic force on the limiting block 44.
[0070] Preferably, referring to Figure 1 , Figure 3 , Figure 8 and Figure 9 , the limiting block 44 is provided with a receiving cavity, and at least part of the elastic member 45 is located in the receiving cavity to increase the connection stability of the elastic member 45 and the limiting block 44. The sleeve 41 is provided with a sliding groove 411 extending in 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 in the third direction, the sliding cooperation of the sliding block 442 and the sliding groove 411 can guide the limiting block 44 to increase the stability of the reciprocating movement of the limiting block 44.
[0071] Further, referring to Figure 3 and Figure 10 , the puncture assembly 3 includes a needle seat 31, a needle body 32 mounted on the needle seat 31, and a sealed housing 33 connected with the needle seat 31, the sealed housing 33 is provided with an abutting portion 331 capable of abutting with the limiting block 44, and during the process of installing the puncture assembly 3 on the connecting piece 2 in the second direction, the abutting portion 331 abuts with the limiting block 44 in the second direction.
[0072] It can be understood that the limiting block 44 can be insertedly connected with the needle seat 31, so that when the sleeve 41 moves in the first direction under the action of the driving member 42, the sleeve 41 drives the limiting block 44 to move, so that the needle seat 31 moves in the first direction along with the sleeve 41, thereby completing the implantation action; and after the implantation action is completed, the switching block 12 is limited to cooperate, 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.
[0073] Specifically, when the puncture assembly 3 is installed in the second direction, the abutting portion 331 abuts with the limiting block 44 in the second direction, and then the limiting block 44 moves in the second direction along with the puncture assembly 3 under the action of the abutting portion 331, so that the limiting block 44 gradually separates from the switching block 12, and the limiting block 44 moves towards the direction close to the puncture assembly 3 under the action of the elastic member 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 sealed housing 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 sealed housing 33, when the puncture assembly 3 is installed in the second direction, the limiting block 44 moves in the second direction along with the puncture assembly 3 to realize the force storage of the driving member 42.
[0074] The structure of the abutting portion 331 is not specifically limited in the present application, and preferably, referring to Figure 3 and Figure 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 the abutting portion 331 can form an avoidance with the guide portion 11 when the puncture assembly 3 is installed, 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.
[0075] In the present embodiment, preferably, referring to Figures 1 to 6 , the housing 1 is provided with the guide portion 11, the connecting piece 2 includes the connecting portion 21 and the clamping portion 22, and the bottom of the guide portion 11 is provided with an avoidance slot 114. When the clamping portion 22 is out of position with the avoidance slot 114, the clamping portion 22 can clamp and fix the puncture assembly 3, and when the clamping portion 22 is opposite to the avoidance slot 114, the clamping portion 22 releases the puncture assembly 3.
[0076] It can be understood that the clamping portion 22 has elasticity, so that when the clamping portion 22 is out of position with the avoidance slot 114, the clamping portion 22 deforms under the action of the inner wall of the guide portion 11 to clamp and fix the puncture assembly 3; and when the clamping portion 22 is opposite to the avoidance slot 114, the clamping portion 22 restores the deformation under the action of its own elasticity and offsets into the avoidance slot 114 to release the puncture assembly 3.
[0077] Specifically, when installing the puncture assembly 3, first align the puncture assembly 3 with the connecting piece 2, then apply a force to the puncture assembly 3 in the second direction, so that the puncture assembly 3 drives the connecting piece 2 to move in the second direction, so that the clamping portion 22 is out of position with the avoidance slot 114, and the clamping portion 22 deforms towards the inside of the guide portion 11 under the action of the cylindrical wall of the guide portion 11, so that the clamping portion 22 clamps and fixes the puncture assembly 3; when disassembling the puncture assembly 3, the connecting piece 2 drives the puncture assembly 3 to move in the first direction, so that the clamping portion 22 moves to a position opposite to the avoidance slot 114, at this time the clamping portion 22 deforms towards the outside of the guide portion 11 through the avoidance slot 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.
[0078] Further, referring to Figure 3 and Figure 6 , the guide portion 11 is provided with an accommodation slot 113 for the limiting block 44 to pass through, so that the limiting block 44 can extend into the inside of the guide portion 11 through the accommodation slot 113 and be inserted and matched with the needle seat 31, to ensure that the needle seat 31 can move in the first direction together with the sleeve 41.
