[0041] Referring to Figures 1 to 9 , an implantation device of a blood glucose monitoring apparatus is disclosed, which comprises a housing 1 having a bottom-opened accommodating cavity, a needle assisting unit and a needle detachment force accumulator 6, wherein the needle assisting unit is arranged in the accommodating cavity and comprises a driving member 2, an elastic reset member 3, a needle seat 4 and a puncture needle 5, the puncture needle 5 is detachably connected with the needle seat 4, the needle seat 4 has a first position for being clamped and matched with the driving member 2 and a second position for being unclamped and matched, the driving member 2 is used for driving the needle seat 4 to move from the first position to the second position along a first direction, the elastic reset member 3 is used for driving the needle seat 4 in the second position to move to a third position along a second direction, and the first direction and the second direction are opposite to each other, and the needle detachment force accumulator 6 is arranged in the housing 1 and can act on the needle seat 4 and the puncture needle 5 so as to make the puncture needle 5 separate from the needle seat 4 along the first direction and make the needle seat 4 recover from the third position to the first position.

[0042] When the implantation device of the blood glucose monitoring apparatus in the present application is used, the driving member 2 drives the needle seat 4, and then the needle seat 4 drives the puncture needle 5 to move to the second position along the first direction, so that the sensor is pierced into the subcutaneous tissue under the action of the puncture needle 5, and then the elastic reset member 3 drives the needle seat 4, so that the needle seat 4 drives the puncture needle 5 to move from the second position to the third position along the second direction, because the first direction and the second direction are opposite to each other, then the puncture needle 5 is withdrawn from the subcutaneous tissue after the needle seat 4 moves from the second position to the third position, so as to complete the auxiliary function of the needle assisting unit for the sensor to pierce into the subcutaneous tissue, then the needle detachment force accumulator 6 is pushed, and then the puncture needle 5 separates from the needle seat 4 along the first direction under the action of the needle detachment force accumulator 6, and the needle seat 4 moves to the first position for being clamped and matched with the driving member 2 under the action of the needle detachment force accumulator 6, so as to realize the reset of the needle seat 4 while the puncture needle 5 is detached, so as to avoid the situation that the user needs to reset the needle seat 4 when the puncture needle 5 is installed again, thereby reducing the difficulty of the user to detach and install the puncture needle 5 and improving the user experience.

[0043] And, since the puncture needle 5 in the application is detachably connected with the needle seat 4, the implantation device of the blood glucose monitoring equipment can be reused except the puncture needle 5, so as to reduce the use cost of the user, and meanwhile, the resource waste caused by the fact that other components cannot be reused is avoided.

[0044] The application does not make specific limitation on the structure of the elastic reset member 3, preferably, referring to Figure 3 、 Figure 4 and Figure 5 , the elastic reset member 3 is a tension spring, one end of the tension spring is hung on the top of the needle seat 4, and the other end of the tension spring is hung on the driving member 2, so as to ensure the elastic reset effect on the needle seat 4. In other embodiments, the elastic reset member 3 can also be an elastic rubber band or other elastic components.

[0045] It should be noted that the reset of the needle seat 4 in the application refers to the movement of the needle seat 4 from the third position to the first position.

[0046] In a preferred embodiment, referring to Figure 3 、 Figure 4 and Figure 5 , the driving member 2 comprises a driving sleeve 21 and an elastic driving part 22 acting on the driving sleeve 21, the driving sleeve 21 has a clamping arm 211 capable of being clamped and matched with the shell 1, so that the driving sleeve 21 has a clamping position in which the clamping arm 211 is clamped and matched with the shell 1, and a needle assisting position below the clamping position, and the elastic driving part 22 is deformed to exert an elastic force on the driving sleeve 21 towards the needle assisting position.

[0047] Since the clamping arm 211 of the driving sleeve 21 is clamped and matched with the shell 1 at the clamping position, and the elastic driving part 22 is deformed at this time, after the clamping and matching of the clamping arm 211 with the shell 1 is released, the driving sleeve 21 can move towards the needle assisting position under the action of the elastic driving part 22, so that the needle seat 4 moves to the second position under the driving action of the driving sleeve 21, thereby realizing the driving of the needle seat 4 towards the second position; in addition, when driving the needle seat 4 towards the second position, only the clamping and matching of the clamping arm 211 with the shell 1 needs to be released, so as to reduce the use difficulty of the user and improve the use experience of the user.

[0048] Specifically, the top end of the tension spring is hung on the top wall inside the driving sleeve 21, so as to ensure that the tension spring can exert an elastic force on the needle seat 4 along the second direction.

[0049] More preferably, the clamping arm 211 is provided with two, so as to increase the stability when the driving sleeve 21 is clamped and matched with the shell 1.

[0050] The application does not make specific limitation on the structure of the elastic driving part 22, preferably, referring to Figure 3 ,Figure 4 and Figure 5 The elastic driving part 22 is a spring, one end of the spring abuts against the driving sleeve 21, and the other end of the spring abuts against the top wall inside the shell 1, so as to ensure the elastic driving effect on the driving sleeve 21. In other embodiments, the elastic driving part 22 can also be an elastic sheet or an elastic column or other elastic structures.

[0051] The application does not make specific limitations on the setting position of the clamping arm 211. Preferably, refer to Figure 4 The clamping arm 211 is located at the side of the driving sleeve 21, and the clamping arm 211 has a clamping protrusion 212 that can protrude from the side wall of the driving sleeve 21. The shell 1 is provided with a clamping opening 11. When the driving sleeve 21 is in the clamping position, the clamping protrusion 212 extends into the clamping opening 11 and is clamped and matched with the opening wall of the clamping opening 11, so that the clamping position of the driving sleeve 21 and the shell 1 is located at the side of the shell 1. When the implanted device of the blood glucose monitoring device is used, it is usually to hold the shell 1 with the hand, so as to further reduce the difficulty of disengaging the clamping arm 211 and the shell 1 from the clamped matching, so that the user does not need to move the hand when disengaging the clamping arm 211 and the shell 1 from the clamped matching, and only needs to press the clamping protrusion 212, thereby further reducing the use difficulty of the user, so as to further improve the use experience of the user.

[0052] Further, refer to Figure 1 and Figure 4 The shell 1 is provided with a needle assisting button 12 outside, the needle assisting button 12 is provided with a pressing protrusion extending into the clamping opening 11, and the needle assisting button 12 can move in the radial direction of the shell 1, so that the clamping protrusion 212 and the clamping opening 11 can be disengaged from the clamped matching by pressing the needle assisting button 12.

[0053] When disengaging the clamping protrusion 212 and the clamping opening 11 from the clamped matching, only the needle assisting button 12 needs to be pressed, thereby avoiding the situation that the user needs to stretch the fingers into the clamping opening 11, so as to reduce the difficulty of disengaging the clamping protrusion 212 and the clamping opening 11 from the clamped matching, further facilitate the user to disengage the clamping arm 211 and the clamping opening 11 from the clamped matching, and reduce the pressure intensity borne by the fingers of the user when the user disengages the clamping protrusion 212 and the clamping opening 11 from the clamped matching, so as to reduce the discomfort of the user, thereby further improving the use experience of the user.

[0054] The application does not make specific limitations on the connection mode of the needle assisting button 12 and the shell 1. Preferably, refer to Figure 2 and Figure 6The two sides of the needle assisting button 12 are provided with L-shaped ribs 121, the shell 1 is provided with a through port 13 for the L-shaped ribs 121 to pass through, and the connection between the needle assisting button 12 and the shell 1 is achieved by the cooperation between the end of the L-shaped rib 121 away from the needle assisting button 12 and the inner wall of the shell 1, so as to increase the connection stability of the needle assisting button 12 and the shell 1, simplify the structure design of the needle assisting button 12, and reduce the production cost of the implantation device of the blood glucose monitoring equipment.

[0055] In other embodiments, the needle assisting button 12 can also be connected to the shell 1 through a thin-walled structure, which not only achieves the connection between the needle assisting button 12 and the shell 1, but also ensures that the needle assisting button 12 can move in the radial direction of the shell 1.

[0056] Further, referring to Figures 1 to 5 The driving sleeve 21 has a pull rod 213 which is arranged in the shell 1 and has an operating end outside the shell 1, so that when the driving sleeve 21 is reset, the operating end only needs to be pulled, thereby reducing the difficulty of resetting the driving sleeve 21 and further improving the user experience; and the operating end can also limit the driving sleeve 21, so as to avoid the separation of the driving sleeve 21 and the shell 1, on the one hand, increasing the connection stability of the driving sleeve 21 and the shell 1, and on the other hand, avoiding the need for the user to reassemble the driving sleeve 21, thereby ensuring the user experience.

[0057] Specifically, the end of the pull rod 213 away from the driving sleeve 21 is provided with a pulling block 214, and the cross-sectional area of the pulling block 214 is greater than that of the pull rod 213, so that the pulling block 214 forms the operating end, so as to facilitate the user to pull the pull rod 213, and the pulling block 214 can be stopped by the top of the shell 1, so as to limit the movement stroke of the driving sleeve 21.

[0058] The position relationship between the pull rod 213 and the driving sleeve 21 is not limited in the application, and preferably, referring to Figures 1 to 5 The pull rod 213 and the driving sleeve 21 are coaxially arranged, so that the pull rod 213 extends out of the shell 1 through the top of the shell 1, so that when the driving sleeve 21 is reset, the user only needs to pull the pull rod 213 in the vertical direction, thereby reducing the difficulty of resetting the driving sleeve 21 and further improving the user experience.

[0059] In other embodiments, the pull rod 213 can also be arranged on the side of the driving sleeve 21, that is, the pull rod 213 extends out of the shell 1 from the side of the shell 1, so as to reduce the height of the implantation device of the blood glucose monitoring equipment.

[0060] It should be noted that the reset of the driving sleeve 21 in the application refers to the movement of the driving sleeve 21 from other positions to the clamping position.

[0061] In other embodiments, the clamping arms 211 can also be located at the top of the driving sleeve 21, that is, the clamping position of the clamping arms 211 and the housing 1 is located at the top of the housing 1.

[0062] In a preferred embodiment, referring to Figure 5 and Figure 7 , the driving member 2 comprises a driving sleeve 21, the inside of the driving sleeve 21 is provided with a clamping wall 215, the needle seat 4 is provided with an elastic arm 41 capable of clamping cooperation with the clamping wall 215, and the housing 1 is provided with an unlocking block 14; when the elastic arm 41 clamps cooperation with the clamping wall 215, the needle seat 4 is in the first position and can move with the driving sleeve 21 towards the needle assisting position; when the elastic arm 41 moves to the position of the unlocking block 14, the needle seat 4 is in the second position, and the unlocking block 14 exerts pressure on the elastic arm 41 to make the elastic arm 41 disengage from the clamping cooperation with the clamping wall 215 and move in the second direction under the action of the elastic restoring member 3.

[0063] After disengaging the clamping cooperation between the driving sleeve 21 and the housing 1, the driving sleeve 21 moves towards the needle assisting position under the action of the elastic driving part 22, so that the needle seat 4 moves with the driving sleeve 21 under the clamping cooperation of the elastic arm 41 and the clamping wall 215, and then the needle seat 4 moves towards the second position, when the needle seat 4 moves to the second position, the elastic arm 41 moves to the position of the unlocking block 14 and contacts the unlocking block 14, so that the unlocking block 14 exerts pressure on the elastic arm 41, the elastic arm 41 elastically deforms and disengages from the clamping cooperation with the clamping wall 215, and then the needle seat 4 moves in the second direction under the action of the elastic restoring member 3, so that the needle seat 4 drives the puncture needle 5 to move, so that the needle seat 4 moves to the third position, and finally the puncture needle 5 withdraws from the biological subcutaneous tissue, to complete the puncture needle 5 assisting the sensor to penetrate into the subcutaneous tissue.

[0064] Specifically, the elastic arm 41 has a locking protrusion 411 protruding from the side of the needle seat 4, the locking protrusion 411 clamps cooperation with the clamping wall 215, and the bottom of the locking protrusion 411 is provided with a guide surface 412 capable of guiding cooperation with the unlocking block 14, so that the unlocking block 14 exerts pressure on the elastic arm 41 under the action of the guide surface 412, to realize the disengagement of the clamping cooperation between the elastic arm 41 and the clamping wall 215.

[0065] More preferably, two elastic arms 41 are oppositely arranged, and the unlocking block 14 is correspondingly provided with two, to increase the stability of the clamping cooperation between the needle seat 4 and the driving sleeve 21.

[0066] The formation method of the clamping wall 215 is not specifically limited in the present application, preferably, referring to Figure 5The driving sleeve 21 is provided with a notch penetrating the bottom of the driving sleeve 21, and the top wall of the notch forms a clamping wall 215. On one hand, the clamping wall 215 can facilitate the assembly of the needle seat 4 into the driving sleeve 21. On the other hand, the outer periphery of the needle seat 4 can abut against the inner wall of the driving sleeve 21, thereby increasing the connection stability between the needle seat 4 and the driving sleeve 21.

[0067] In other embodiments, the inner wall of the driving sleeve 21 is provided with a blocking rib, and the bottom surface of the blocking rib forms the clamping wall 215.

[0068] Further, the elastic arm 41 has an initial position and an unlocking position. In the initial position, the driving sleeve 21 is in the clamping position, and the elastic arm 41 is clamped with the clamping wall 215. In the unlocking position, the elastic arm 41 contacts the unlocking block 14, and the distance between the clamping position and the needle assisting position of the driving sleeve 21 is greater than the distance between the initial position and the unlocking position of the elastic arm 41. When the elastic arm 41 is in the unlocking position, the needle body of the puncture needle 5 at least partially extends out of the accommodating cavity, thereby achieving the disengagement of the needle seat 4 from the clamping of the driving sleeve 21 before the driving sleeve 21 moves to the needle assisting position. This can shorten the movement stroke of the puncture needle 5, thereby reducing the length of the puncture needle 5 extending out of the accommodating cavity, reducing the depth of the puncture needle 5 penetrating into the subcutaneous tissue, and reducing the pain of the user, thereby greatly improving the user experience.

[0069] The present application does not make specific limitations on the detachable connection mode of the puncture needle 5 and the needle seat 4. Preferably, referring to Figure 3 、 Figure 4 and Figure 5 , the needle seat 4 has at least two connection portions 42 arranged along the circumference of the puncture needle 5. The plurality of connection portions 42 collectively form an accommodating space for accommodating the puncture needle 5. The puncture needle 5 is in interference fit with the accommodating space, thereby increasing the connection stability of the puncture needle 5 and the needle seat 4, and reducing the difficulty of disassembling the puncture needle 5, thereby reducing the force required to be applied to the needle disengagement force storage member 6 when disassembling the puncture needle 5, achieving the effect of facilitating the user to disassemble the puncture needle 5, and further improving the user experience.

[0070] The present application does not make specific limitations on the structure of the connection portion 42. Preferably, the connection portion 42 is an arc-shaped rib structure, which can increase the contact area between the connection portion 42 and the puncture needle 5, thereby increasing the connection stability of the puncture needle 5 and the needle seat 4. The connection portion 42 has elasticity, which can achieve elastic clamping of the puncture needle 5, thereby further increasing the connection stability of the puncture needle 5 and the needle seat 4. In other embodiments, the connection portion 42 can also be a rib structure.
