Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0051] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. The "connection", "coupling" in this application, unless otherwise specified, includes direct connection, indirect connection and contact connection (coupling) and the like.

[0052] The analyte sensor implanting device is used for inserting the analyte sensor of the monitor into the human body, and the analyte sensor usually needs to be implanted into the human body with the help of a guide needle. The monitor and the analyte sensor can adopt any feasible existing structure, such as the analyte sensor can be a sensor for detecting the blood sugar of the human body, and the monitor can be an instrument for monitoring the blood sugar of the human body.

[0053] In one embodiment, referring to Figures 1 to 5 The analyte sensor implanting device includes a monitor 1 and an analyte sensor needle helper 2, and the monitor 1 includes an analyte sensor 11. The monitor 1 can be an instrument for monitoring physiological parameters of the human body.

[0054] The analyte sensor needle helper 2 includes a pressing unlocking shell 21, a mounting piece 22, a guide needle 26 for implanting the analyte sensor into the human body, an implanting driving frame 23 for driving the guide needle 26, and an implanting elastic piece 24 for applying an elastic force to the implanting driving frame 23. The proximal end of the pressing unlocking shell 21 is a pressing end 211 for pressing operation, and the distal end has an opening 212 for facing the human body. The mounting piece 22 and the implanting driving frame 23 are both assembled in the pressing unlocking shell 21. The implanting elastic piece 24 is used to apply an elastic force to the implanting driving frame 23 to make the implanting driving frame 23 move towards the distal end. The guide needle 26 is assembled on the implanting driving frame 23.

[0055] The implanting driving frame 23 includes a locking structure 231 for locking the mounting piece 22 and the implanting driving frame 23. Before using the analyte sensor implanting device, the relative position of the implanting driving frame 23 and the mounting piece 22 is locked and cannot move relatively. When it is needed to implant the analyte sensor 11 into the human body, the locking structure 231 needs to be unlocked. The pressing unlocking shell 21 has an unlocking part 213 for unlocking the locking effect of the locking structure 231. The unlocking part 213 is used to contact the locking structure 231 to release the locking effect of the locking structure 231 on the implanting driving frame 23, so that the implanting driving frame 23 moves towards the distal end under the elastic force of the implanting elastic piece 24, that is, moves towards the human body relative to the mounting piece 22.

[0056] The analyte sensor assisting needle further comprises an unlocking shell holding structure 27 for exerting a holding force on the pressing unlocking shell 21 to keep the position of the pressing unlocking shell 21. In one embodiment, the unlocking shell holding structure 27 is on the implant driving frame 23. In some other embodiments, the unlocking shell holding structure 27 can also be on the mounting member 22, and in some other embodiments, the number of the unlocking shell holding structure 27 can be more than two, part of which is on the mounting member 22 and part of which is on the implant driving frame 23.

[0057] The pressing unlocking shell 21 has a holding release structure 214 which is in contact with the unlocking shell holding structure 27 after the pressing unlocking shell 21 is pressed, so as to overcome the holding force of the unlocking shell holding structure 27 on the pressing unlocking shell 21 and release the holding force of the unlocking shell holding structure 27 on the pressing unlocking shell 21, so that the unlocking part 213 can unlock the locking structure 231. The size of the holding force is selected within a reasonable range according to the force with which the pressing unlocking shell 21 is pressed. The unlocking shell holding structure 27 releases the holding of the pressing unlocking shell 21 after the pressing unlocking shell 21 is pressed and the holding force is overcome, which can prevent accidental touch.

[0058] It should be noted that the distal end and the proximal end in the present application are described based on the position of the operator, wherein the proximal end is the end close to the operator and the distal end is the end away from the operator.

[0059] It should be noted that the guide needle 26 can be directly assembled on the implant driving frame 23 or assembled on the implant driving frame 23 through other parts. For example, in one embodiment, the implant driving frame 23 comprises a guide needle frame 25 and a monitor frame 230 for mounting the monitor 1. The guide needle 26 is mounted on the guide needle frame 25, and the guide needle frame 25 is mounted on the monitor frame 230. When the monitor frame 230 moves to the distal end under the action of the implant elastic member 24, the guide needle frame 25 also moves to the distal end. The guide needle 26 is assembled on the guide needle frame 25 and is used for implanting the analyte sensor 11 of the monitor 1 into the human body. In some other embodiments, the monitor can also be mounted on the mounting member, and at this time the implant driving frame comprises a guide needle frame and a linkage frame, and the locking structure is used for locking the linkage frame and the mounting member.

[0060] In one embodiment, please refer to Figure 2 The unlocking shell holding structure 27 is at the proximal end of the implant driving frame 23. In this way, the unlocking shell holding structure 27 and the pressing unlocking shell 21 can interact with each other. In some other embodiments, the unlocking shell holding structure 27 can also be arranged at the distal end of the pressing unlocking shell 21.

[0061] Specifically, in one embodiment, the unlocking shell holding structure 27 is on the monitor frame 230.

[0062] Specifically, in one embodiment, referring to Figures 2 to 4 The unlocking shell holding structure 27 includes a holding arm 271 extending from the distal end of the implant driving frame 23 to the proximal end, and the holding arm 271 holds the position of the pressing unlocking shell 21 by abutting against the pressing unlocking shell 21. In some other embodiments, the holding arm 271 extends from the distal end of the monitor frame 230 to the proximal end.

[0063] In some other embodiments, the unlocking shell holding structure 27 can also use a spring sheet in addition to the holding arm 271.

[0064] Further, in one embodiment, referring to Figure 2 The holding release structure 214 includes a holding release arm 215 inside the pressing unlocking shell 21, the holding release arm 215 extends from the proximal end of the pressing unlocking shell 21 to the distal end of the pressing unlocking shell 21, the distal end of the holding release arm 215 abuts against the proximal end of the holding arm 271, at least one of the holding arm 271 and the holding release arm 215 is a spring arm, the distal end of the holding release arm 215 and the proximal end of the holding arm 271 both have abutting slopes, the abutting slope of the distal end of the holding release arm 215 is a holding release arm slope 2151, the abutting slope of the proximal end of the holding arm 271 is a holding arm slope 2711, the holding release arm slope 2151 and the holding arm slope 2711 are both used to guide the deformation of the spring arm after the pressing unlocking shell 21 is pressed, release the abutting relationship between the holding release arm 215 and the holding arm 271, thereby releasing the holding effect of the unlocking shell holding structure 27. In one embodiment, referring to Figure 2 The holding arm 271 is a spring arm, and the holding release arm 215 is a rigid arm. In some other embodiments, the holding arm 271 is a rigid arm, and the holding release arm 215 is a spring arm. In some other embodiments, the holding arm 271 and the holding release arm 215 are both spring arms.

[0065] In some other embodiments, only the distal end of the holding release arm 215 can have the holding release arm slope 2151, and the proximal end of the holding arm 271 can have a flat surface in contact with the holding release arm slope 2151, and the flat surface is perpendicular to the direction of movement of the implant driving frame 23. In some other embodiments, only the proximal end of the holding arm 271 can have the holding arm slope 2711. It should be noted that the slope in the present application refers to a surface with a certain slope in the direction of movement of the implant driving frame 23, and the slope can be an inclined surface, a convex surface, or a concave surface.

[0066] In one embodiment, referring to Figures 2 to 5, in order to improve the effect of preventing accidental touch, the retaining arm 271 comprises an inclined section 2712, the inclined section 2712 is used to abut against the retaining release arm 215, one end of the inclined section 2712 is a retaining arm slope surface 2711. In the direction from the distal end to the proximal end of the retaining arm 271, the inclined section 2712 gradually inclines to the distal end of the retaining release arm 215. In this way, when the pressing unlocking shell 21 is pressed to make the retaining release arm 215 abut against the retaining arm slope surface 2711 on the inclined section 2712, a greater force is required to make the retaining arm 271 elastically deform, and then release the retaining effect of the retaining arm 271 on the pressing unlocking shell 21.

[0067] In an embodiment, please refer to Figure 2 , in order to facilitate the release of the locking of the implant driving frame 23, the minimum force required for the retaining release structure 214 to release the retaining effect of the unlocking shell retaining structure 27 on the pressing unlocking shell 21 is the first force, the minimum force required for the unlocking part 213 to release the locking effect of the locking structure 231 on the implant driving frame 23 is the second force, and the first force is greater than the second force. In this way, the effect of preventing accidental touch can be improved, and the implant driving frame 23 can be more smoothly unlocked, and the overall operation is more smooth.

[0068] In some other embodiments, according to actual needs, the first force can also be less than or equal to the second force.

The retaining release structure 214 and the unlocking part 213 are arranged alternately in the circumferential direction of the pressing unlocking shell 21. Specifically, in an embodiment, the number of the retaining release arm 215 is two or more, the unlocking part 213 is an unlocking arm 2131, the unlocking arm 2131 extends from the proximal end of the pressing unlocking shell 21 to the distal end of the pressing unlocking shell 21, the number of the unlocking arm 2131 is two or more, and the unlocking arm 2131 and the retaining release arm 215 are arranged alternately in the circumferential direction of the pressing unlocking shell 21.

[0070] Further, in an embodiment, please refer to Figure 2 , the unlocking arm 2131 extends from the proximal end of the pressing unlocking shell 21 to the distal end of the pressing unlocking shell 21, the unlocking arm 2131 releases the locking by abutting against the locking structure 231, and the length of the unlocking arm 2131 is not less than the length of the retaining release arm 215. In this way, after the abutting relationship between the retaining release arm 215 and the retaining arm 271 is released, the unlocking arm 2131 releases the locking of the locking structure 231.

[0071] Further, in an embodiment, please refer to Figure 2 andFigure 5 Specifically, in one embodiment, the locking structure 231 is used to lock the mounting member 22 and the monitor frame 230. In one embodiment, the locking structure 231 comprises a locking arm 2311 extending from the distal end of the implant driving frame 23 to the proximal end, and the proximal end of the locking arm 2311 is provided with a clamping hook 2312. The clamping hook 2312 is clamped on the mounting member 22 to achieve the locking of the implant driving frame 23 and the mounting member 22. The unlocking portion 213 deforms the locking arm 2311 by abutting against the clamping hook 2312 to achieve the separation of the clamping hook 2312 and the mounting member 22.

[0072] Specifically, in one embodiment, please refer to Figure 2 and Figure 5 , the locking arm 2311 is on the monitor frame 230.

[0073] In one embodiment, please refer to Figure 2 , in order to facilitate the unlocking of the clamping hook 2312, the clamping hook 2312 is provided with a clamping hook slope 2313, and the end of the unlocking arm 2131 is provided with an unlocking arm slope. Through the cooperation of the unlocking arm slope and the clamping hook slope 2313, the clamping hook 2312 can be applied with a force to separate the clamping hook 2312 and the mounting member 22.

[0074] Further, in one embodiment, please refer to Figures 2 to 4 , the mounting member 22 is sleeve-shaped, the implant driving frame 23 is installed in the mounting member 22, and the mounting member 22 can guide the implant driving frame 23 to move linearly. In this way, the rotation of the implant driving frame 23 can be prevented, and the movement of the implant driving frame 23 is smoother.

[0075] Further, in one embodiment, please refer to Figures 2 to 4 , the implant elastic member 24 is a spring, and the implant elastic member 24 is clamped between the monitor frame 230 and the mounting member 22. After the locking of the monitor frame 230 and the mounting member 22 is released, under the action of the spring, the monitor frame 230 moves towards the human body, driving the guide needle frame 25 and the guide needle 26 to pierce the human skin, and then the analysis sensor is implanted into the human body under the action of the guide needle 26. The spring is clamped between the monitor frame 230 and the mounting member 22 and is in a compressed state.

[0076] In one embodiment, the guide needle frame 25 and the monitor 1 can adopt any feasible structure form in the prior art. Please refer to Figure 2The implant driving frame 23 and the guide needle frame 25 are provided with a needle returning elastic member 28. After the analyte sensor 11 is implanted into the human body, the guide needle frame 25 and the implant driving frame 23 can move relative to each other. Under the action of the needle returning elastic member 28, the guide needle 26 is extracted from the human body. The part of the monitor 1 in contact with the human body is provided with an adhesive piece 12. Under the action of the adhesive piece 12, the monitor 1 is separated from the implant driving frame 23, and the monitor 1 remains on the surface of the human skin. After the implantation of the analyte sensor 11 is completed, the analyte sensor needle helper 2 is removed by operating the press unlocking shell 21, and the monitor 1 adhered to the surface of the human body can monitor the parameters of the human body in real time.

[0077] In an embodiment, please refer to Figure 2 The monitor 1 and the analyte sensor 11 are both built-in in the analyte sensor needle helper 2.

[0078] The present application realizes the anti-mis-touch function through the unlocking shell retaining structure, without the need for the user to disassemble the anti-mis-touch part, which is more convenient for the user to use. In the present application, the press unlocking shell of the needle helper serves as a key, without the need for separately increasing a key part, thereby reducing the manufacturing cost. Meanwhile, the area of the press unlocking shell is larger than that of a separate key, which is more convenient for the user to use.

[0079] In an embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The monitor frame 230 further includes a blocking structure 232. The blocking structure 232 blocks the guide needle frame 25 in the direction away from the human body, so that when the monitor frame 230 moves to the implantation position, it can drive the guide needle frame 25 to move in the direction close to the human body, and then drive the guide needle to move in the direction of penetrating into the human body.

[0080] The mounting part 22 further includes a releasing structure 221. When the monitor frame 230 moves to the implantation position and the guide needle 26 implants the biosensor 11 into the human body, the releasing structure 221 applies a force to the blocking structure 232 to release the blocking of the guide needle frame 25 by the blocking structure 232.

[0081] The biosensor needle helper further includes a needle returning elastic member 28. The needle returning elastic member 28 is used to apply a needle returning elastic force to the guide needle frame 25. After the blocking of the guide needle frame 25 by the blocking structure 232 is released, the needle returning elastic force drives the guide needle frame 25 to extract the guide needle 26.

[0082] In an embodiment, please refer toFigures 2 to 4 The needle returning spring 28 is between the guide needle holder 25 and the monitor holder 230 and is always in compression. In one embodiment, the implant spring 24 is between the mounting member and the monitor holder 230 and is always in compression. In one embodiment, the needle returning spring 28 and the implant spring 24 are both coil springs. Coil springs are simple in structure and easy to install.

[0083] Regarding the form of the stop structure 232, in one embodiment, please refer to Figure 4 and Figure 5 The retaining arm 271 forms at least part of the stop structure 232. The stop structure 232 includes a stop portion 2321 on the retaining arm 271, which is used to stop the guide needle holder 25.

[0084] Regarding the form of the stop structure 232, in one embodiment, please refer to Figure 4 and Figure 5 The release structure 221 includes a release protrusion 2211 on the mounting member 22, which has a protrusion slope 2212 used to cooperate with the retaining arm 271 to elastically deform the retaining arm 271 away from the release protrusion 2211.

[0085] Regarding the form of the stop structure 232, in one embodiment, please refer to Figures 1 to 5 The implanting process of the analyte sensor 11 implanting device is as follows:

[0086] When it is necessary to implant the analyte sensor 11 into the human body, the protective cover 29 of the analyte sensor implanting device is opened, the sensor cap 210 is removed, the opening 212 of the pressing unlocking shell 21 is directed to the position of the human body where the sensor needs to be implanted, the pressing end 211 of the pressing unlocking shell 21 is pressed, the retaining release structure 214 of the pressing unlocking shell 21 is in contact with the unlocking shell retaining structure 27, the retaining force of the unlocking shell retaining structure 27 on the pressing unlocking shell 21 is overcome, the retaining effect of the unlocking shell retaining structure 27 on the pressing unlocking shell 21 is released, and the unlocking portion 213 can unlock the locking structure 231. After the implanting drive holder 23 is unlocked, it moves towards the human body under the action of the implant spring 24, drives the guide needle holder 25 and the guide needle 26 to move, and makes the guide needle 26 implant the analyte sensor 11 into the human body. After the analyte sensor 11 is implanted into the human body, the guide needle holder 25 and the implanting drive holder 23 can move relative to each other, and the guide needle 26 is extracted from the human body under the action of the needle returning spring 28. After the implanting of the analyte sensor 11 is completed, the analyte sensor needle helper 2 is removed by operating the pressing unlocking shell 21, the monitor 1 is separated from the implanting drive holder 23 under the action of the adhesive sheet 12, and the monitor 1 is adhered to the surface of the human body to monitor the parameters of the human body in real time.

[0087] In an embodiment of the analyte sensor needle helper, the analyte sensor needle helper has the same structure as the analyte sensor needle helper in any of the above embodiments, and will not be repeated here.

[0088] The above application of specific examples to illustrate the application, is used to help understand the application, and not to limit the application. For the skilled in the art to which the application belongs, according to the idea of the application, can make a number of simple deduction, deformation or replacement.
