[0042] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0043] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct connection, indirect connection and contact connection (coupling), etc.

[0044] In one embodiment, please refer to Figures 1 to 9 The analyte sensor implantation device comprises a monitor 1 and a needle aid 2, wherein the monitor 1 comprises an analyte sensor 11. The monitor 1 may be an instrument for monitoring physiological parameters of a human body.

[0045] The needle-assisting device 2 is used to insert the analyte sensor 11 of the monitor 1 into the human body. The analyte sensor 11 usually needs to be implanted into the human body with the help of an introducer needle 26. The monitor 1 and the analyte sensor 11 can adopt any feasible existing structure. For example, the analyte sensor 11 can be a sensor for detecting human blood sugar, and the monitor 1 can be an instrument for monitoring human blood sugar.

[0046] The needle assist device includes a shell assembly 20, a monitor frame 23 movably mounted in the shell assembly 20, a guide needle frame 25 disposed on the monitor frame 23, and a guide needle 26 mounted on the guide needle frame 25, wherein the guide needle 26 is used to pierce the skin to implant the analyte sensor 11.

[0047] The monitor 1 is installed on the monitor frame 23 by means of adsorption and / or adhesion and / or interference fitting. The monitor 1 includes an applicator 12 for applying to the skin. When the monitor 1 and the monitor frame 23 are separated under the action of external force, the adhesive force between the applicator 12 and the skin 3 can enable the monitor 1 to remain on the skin 3 through the applicator 12.

[0048] Usually, after the analyte sensor 11 is implanted in the human body, the auxiliary needle 2 needs to be removed. In the present application, the force between the monitor 1 and the monitor frame 23 can satisfy the following conditions: when the auxiliary needle 2 is removed, the patch will not separate from the skin, and the patch will not separate from the monitor, and the monitor 1 can remain on the skin through the patch 12.

[0049] In one embodiment, the bonding force between the patch 12 and the skin 3 is greater than the force between the monitor 1 and the monitor frame 23, the monitor 1 is separated from the monitor frame 23, and the monitor 1 remains on the human skin. Of course, considering the factor of gravity, on the basis of being able to achieve the monitor remaining on the human skin after the needle aid is removed, the bonding force between the patch 12 and the skin 3 can also be equal to or less than the force between the monitor 1 and the monitor frame 23.

[0050] In one embodiment, the dressing 12 is an adhesive dressing, and the dressing 12 is attached to the skin by bonding.

[0051] Since the monitor 1 of the analyte sensor implant device is fixed to the monitor frame 23 by adsorption or adhesion, there is no need to set a buckle on the monitor 1, nor is there a groove adapted to the buckle. After the monitor 1 is separated from the monitor frame 23, it is not easy to come off the user's skin after being scratched, which is convenient for the user's normal use.

[0052] In one embodiment, the monitor 1 has a bonding surface, and the monitor 1 is mounted on the monitor frame 23 by adsorption and / or adhesion and / or interference fit of the bonding surface. In one embodiment, the bonding surface can be a plane, a smooth curved surface, or partly a plane and partly a smooth curved surface. In one embodiment, the smooth curved surface is an outward convex curved surface.

[0053] Regarding the installation method of the monitor 1 and the monitor stand 23, in one embodiment, please refer to Figure 3 The monitor 1 is mounted on the monitor frame 23 by means of magnetic adsorption.

[0054] It is important to understand that there are many ways to install via magnetic adsorption:

[0055] In one embodiment, there is a first magnetic attraction between the monitor 1 and the monitor frame 23, and the direction of the first magnetic attraction is the same as or opposite to the direction in which the guide needle 26 penetrates the skin. At this time, the monitor 1 is installed on the monitor frame 23 by adsorption.

[0056] In another embodiment, there is a second magnetic attraction between the monitor 1 and the monitor frame 23, and the angle between the direction of the second magnetic attraction and the direction in which the guide needle 26 penetrates the skin is greater than 0 degrees and less than 180 degrees. For example, when the angle between the direction of the second magnetic attraction and the direction in which the guide needle 26 penetrates the skin is 90 degrees, and when the penetration direction of the guide needle 26 is vertical, the second magnetic attraction is used to provide pressure between the monitor 1 and the monitor frame 23, and the monitor 1 and the monitor frame 23 will not separate under the action of friction. Specifically, in one embodiment, please refer to Figure 3 and Fig. 9 A magnet 234 is fixed on the monitor frame 23, and the monitor 1 includes a battery 13, and the battery 13 includes a battery shell that can be attracted to the magnet 234. After the patch 12 is attached to the human skin 3, the adhesive force of the patch 12 is relatively large, and when the needle assisting device 2 is removed, the monitor 1 is separated from the monitor frame 23. In one embodiment, the battery shell is made of a ferromagnetic material that can be attracted by a magnet.

[0057] By using the principle of magnetic attraction, the magnet 234 is fixed on the monitor frame 23, and the battery is attracted by the magnet 234, so that the monitor 1 is fixed to the monitor frame 23. At the same time, because there is an applicator 12 at the bottom of the monitor 1, after the monitor 1 is attached to the skin 3, the adhesive force of the applicator 12 can separate the monitor 1 from the monitor frame 23 when the needle aid is removed. In one embodiment, the adhesive force of the applicator 12 is greater than the suction force of the magnet 234.

[0058] In another embodiment, the monitor 1 includes an instrument magnet, and the monitor 1 is fixed on the monitor frame 23 by adsorption of the instrument magnet and the magnet 234. Of course, in some other embodiments, the monitor 1 may be provided with an instrument magnet, and the monitor frame 23 may be provided with a magnetic member, and the magnetic member can be attracted to the instrument magnet.

[0059] In addition to the magnetic adsorption method, an electrostatic adsorption method can also be used. In one embodiment, please refer to Figure 8 The monitor 1 is attached to the monitor stand 23 by electrostatic adsorption.

[0060] Specifically, in one embodiment, please refer to Figure 8 The monitor 1 is fixed on the monitor frame 23 through the electrostatic film 2102. The electrostatic film 2102 includes an electrostatic adsorption surface and an adhesive surface. The electrostatic film 2102 is fixed on the monitor frame 23 through the adhesive surface and is fixed to the monitor 1 through the electrostatic adsorption surface. The adhesive force of the adhesive surface is greater than the electrostatic adsorption force of the electrostatic adsorption surface.

[0061] An electrostatic film 2102 is attached to the monitor frame 23, with the adhesive side attached to the monitor frame 23, and the other side of the electrostatic film 2102 is attached to the monitor 1. At the same time, since there is an applicator 12 at the bottom of the monitor 1, after the monitor 1 is attached to the skin 3, the adhesive force of the applicator 12 can separate the monitor 1 from the monitor frame 23 when the needle aid 2 is removed.

[0062] When the monitor 1 is separated from the monitor frame 23, the electrostatic film 2102 is also separated from the monitor 1 and remains on the monitor frame 23. In one embodiment, the adhesive force of the applicator 12 is greater than the adhesive force of the adhesive surface of the electrostatic film 2102, and is also greater than the electrostatic adsorption force of the electrostatic adsorption surface on the electrostatic film 2102.

[0063] In addition to the magnetic and electrostatic adsorption methods, an adhesive method may also be used. In one embodiment, the monitor 1 is adhered to the monitor frame 23 by adhesive.

[0064] Specifically, in one embodiment, the monitor 1 is bonded to the monitor frame 23 by double-sided tape, the double-sided tape has a first tape surface and a second tape surface, the first tape surface is bonded to the monitor frame 23, and the second tape surface is bonded to the monitor 1, and the bonding force of the first tape surface is greater than the bonding force of the second tape surface, so that after the monitor 1 is separated from the monitor frame 23, the double-sided tape remains on the monitor frame 23.

[0065] By using the principle of strong and weak adhesive, after the monitor 1 is attached to the skin 3, because the first adhesive surface is adhered to the monitor frame 23 and the second adhesive surface is adhered to the monitor 1, when the monitor 1 is separated from the monitor frame 23, the second adhesive surface is also separated from the monitor 1, so that the double-sided adhesive remains on the monitor frame 23. In one embodiment, the adhesive force of the patch 12 is greater than the adhesive force of the first adhesive surface, and also greater than the adhesive force of the second adhesive surface.

[0066] In addition to the above methods, in one embodiment, please refer to Figure 7 The monitor 1 is fixed to the monitor frame 23 by vacuum adsorption, and the monitor 1 is adsorbed on the monitor frame 23 by vacuum adsorption. The monitor frame 23 has a vacuum channel 236, and one end of the vacuum channel 236 is located on the monitor frame adsorption surface 235. The analyte sensor implantation device includes a sealing plug 2101 for blocking the vacuum channel 236. When the guide needle frame 25 is driven to move in the direction of extracting the guide needle 26, the sealing of the sealing plug 2101 is released, and the vacuum adsorption effect between the monitor 1 and the monitor frame 23 disappears, and the monitor 1 and the monitor frame 23 can be separated.

[0067] In one embodiment, please refer to Figure 7Under the action of vacuum, the monitor 1 is adsorbed on the adsorption surface 235 of the monitor frame. In some other embodiments, a cavity can also be formed between the monitor and the monitor frame, and the monitor can be adsorbed on the monitor frame after the cavity is evacuated.

[0068] Specifically, the sealing of the sealing plug 2101 can be released by the user's operation or by other parts of the needle-assisting device 2. For example, in one embodiment, please refer to Figures 2 to 7 The monitor frame 23 includes a locking structure 231 for locking the shell component 20 with the monitor frame 23. Before the analyte sensor 11 is implanted in the device, the relative position of the monitor frame 23 and the shell component 20 is locked and cannot move relative to each other. When the analyte sensor 11 needs to be implanted in the human body, the locking structure 231 needs to be unlocked. The analyte sensor implantation device also includes an implantation elastic member and a return needle elastic member for applying an implantation elastic force to the monitor frame 23. The implantation elastic force is used to drive the monitor frame 23 to move toward the human body after the locking structure is unlocked. The activity stroke of the monitor frame 23 has an initial position and an implantation position. At the initial position, the monitor frame 23 is locked by the locking structure 231. At the implantation position, the guide needle 26 can implant the analyte sensor 11 into the human body. The implantation elastic member 24 is used to apply an implantation elastic force to the monitor frame 23. The implantation elastic force is used to drive the monitor frame 23 to move toward the implantation position after the locking structure 231 is released.

[0069] The shell assembly 20 includes an unlocking portion 213, which is used to contact the locking structure 231 to release the locking effect on the monitor frame 23. The unlocking portion 213 is used to contact the locking structure 231 to release the locking effect of the locking structure 231 on the monitor frame 23, so that the monitor frame 23 moves toward the distal end under the elastic force of the implanted elastic member 24, that is, moves toward the human body relative to the mounting member 22.

[0070] The monitoring frame 23 also includes a stopping structure 232, which stops the guide needle frame 25 in the direction away from the human body, so that when the monitoring frame 23 moves toward the implantation position, it can drive the guide needle frame 25 to move toward the human body, and then drive the guide needle to move in the direction of penetrating the human body.

[0071] The housing assembly 20 further includes a release structure 221. When the monitor frame 23 moves to the implantation position, the guide needle 26 implants the analyte sensor 11 into the human body, and the release structure 221 releases the blocking of the guide needle frame 25 by the blocking structure 232. The return needle elastic member 28 is used to apply a return needle elastic force to the guide needle frame 25. After the blocking effect of the stop structure 232 on the guide needle frame 25 is released, the return needle elastic force drives the guide needle frame 25 to withdraw the guide needle 26.

[0072] When the guide needle holder 25 is driven by the needle return elastic member 28 to move in the direction of withdrawing the guide needle 26 , the guide needle holder 25 releases the seal of the sealing plug 2101 .

[0073] Further, in one embodiment, please refer to Figure 7 The sealing plug 2101 is installed on the guide needle frame 25. When the guide needle frame 25 is driven by the return needle elastic member 28 to extract the guide needle 26, the sealing plug 2101 is pulled out of the vacuum channel 236 by the guide needle frame 25.

[0074] Specifically, in one embodiment, the guide needle holder 25 has a sealing plug hole 252, and the sealing plug hole 252 is a variable diameter hole. One end of the sealing plug 2101 has a blocking cap 2103, and the blocking cap 2103 is located in the large diameter section of the sealing plug hole 252. The guide needle holder 25 and the blocking cap 2103 are blocked, so that the guide needle holder 25 can pull out the sealing plug 2101 when the guide needle 26 is pulled out.

[0075] Regarding the method of achieving vacuum adsorption, in one embodiment, the gap between the monitor and the monitor frame can be evacuated by inserting the sealing plug 2101 through a syringe. In one embodiment, the gap between the monitor and the monitor frame can also be evacuated by setting a vacuum pipeline. In order to prevent air leakage, a one-way valve can be set on the vacuum pipeline. In order to improve the effect of vacuum adsorption, in one embodiment, a sealing ring can be set on the monitor frame adsorption surface 235 on the monitor frame for sealing to prevent air leakage.

[0076] In addition to the above-mentioned methods, in one embodiment, the monitor 1 is installed on the monitor frame 23 by interference fitting. At this time, the monitor is fixed by the friction between the monitor frame and the monitor frame.

[0077] Specifically, in one embodiment, the monitor 1 is interference-fitted with the monitor frame 23 through the peripheral wall surface. Further, the monitor 1 is interference-fitted with the monitor frame 23 through the peripheral wall surface.

[0078] In one embodiment, in order to facilitate assembly, an elastic member is provided on the monitor, and the monitor is interference-fitted with the monitor frame through the elastic member. When the interference fit occurs, the deformation is large, and it is easier to install. In some other embodiments, an elastic member can also be provided on the monitor frame to have an interference fit with the monitor. In one embodiment, the elastic member is an elastic sleeve. Specifically, the elastic sleeve can be a rubber sleeve.

[0079] In some other embodiments, the monitor 1 and the monitor frame 23 may be fixed by any two or more of the following methods: magnetic adsorption, electrostatic adsorption, adhesive adhesion, and interference fit.

[0080] In order to facilitate the understanding of the analyte sensor implant device, the structure of the analyte sensor implant device is explained below by way of example. It should be understood that the installation structure of the monitor 1 and the monitor frame 23 in the present application can be used not only for the analyte sensor implant device introduced in the present application, but also for the existing technology or future analyte sensor implant devices, as long as the monitor 1 and the monitor frame 23 in the analyte sensor implant device need to be fixed together first and then separated after the monitor 1 is applied to the skin.

[0081] In one embodiment, please refer to Figures 2 to 6 The needle-assisting device uses a locking structure 231 to lock the monitor frame 23 and the shell assembly 20. After the locking structure 231 is unlocked by the unlocking part 213, the monitor frame 23 moves toward the direction close to the human body under the elastic force of the implanted elastic member 24. Under the action of the blocking structure 232, the monitor frame 23 can drive the guide needle frame 25 to move, and the guide needle 26 is inserted into the human body to achieve the implantation of the analyte sensor 11. Compared with the current method of controlling the insertion depth of the guide needle 26 of the implant device by manual pressing force, the insertion of the guide needle 26 is completed by applying elastic force by the implanted elastic member 24, which reduces the requirements for manual operation strength. After the guide needle 26 is inserted into the human body and is in place, the releasing structure 221 on the shell assembly 20 can exert a force on the stopping structure 232, thereby releasing the stopping effect of the stopping structure 232 on the guide needle holder 25. In this way, the guide needle holder 25 can move away from the human body under the action of the return needle elastic force of the return needle elastic member 28, thereby pulling the guide needle 26 out of the human body. Under the action of the implant elastic member 24, the guide needle 26 can be inserted into place, and the releasing structure 221 can stably complete the releasing effect on the stopping structure 232, thereby reducing the operating difficulty for the operator.

[0082] In one embodiment, please refer to Figures 2 to 4 , the return needle elastic member 28 is between the guide needle frame 25 and the monitor frame 23 and is always in a compressed state. In one embodiment, the implant elastic member 24 is between the mounting member and the monitor frame 23 and is always in a compressed state. In one embodiment, the return needle elastic member 28 and the implant elastic member 24 are both coil springs. The coil spring has a simple structure and is easy to install.

[0083] In one embodiment, the release structure 221 releases the blocking structure 232 from blocking the guide needle holder 25 by applying a force to the blocking structure 232. In some other embodiments, the release structure 221 can also limit the blocking structure 232. When the restriction is released, the blocking structure 232 can automatically release the blocking by its own elastic force or under the force of other components.

[0084] Further, in one embodiment, please refer to Figures 2 to 5At least part of the blocking structure 232 is an elastic structure, which is elastically deformed after the release structure 221 applies a force to release the blocking of the guide needle holder 25. The blocking structure 232 is an elastic structure, which makes it easier for the release structure 221 to release the blocking effect of the blocking structure 232 on the guide needle holder 25.

[0087] In one embodiment, please refer to Figures 2 to 6 , the release structure 221 applies a force to the bracket elastic arm 2321 to deform the bracket elastic arm 2321, so as to release the blocking relationship between the blocking portion 2322 and the guide needle holder 25. In some other embodiments, in addition to the bracket elastic arm 2321, the blocking structure 232 may also include a rigid bracket and an elastic sheet fixed on the rigid bracket, the elastic sheet blocks the guide needle holder 25, and the blocking structure 232 releases the blocking effect of the elastic sheet by deforming the elastic sheet.

[0089] Regarding the release structure 221, in one embodiment, please refer to Figure 2 and Figure 4 The release structure 221 includes a release protrusion 2211 on the shell assembly 20 . The release protrusion 2211 has a protruding slope 2212 . The protruding slope 2212 is used to cooperate with the contact slope 23214 to elastically deform the bracket elastic arm 2321 in a direction away from the release protrusion 2211 .

[0090] Furthermore, in one embodiment, the proximal end of the needle assisting device 2 is the operating end, and the distal end is the human body contact end for contacting the human body. It should be noted that the distal end and the proximal end in this application are described based on the operator's operating position, wherein the proximal end is the end close to the operator, and the distal end is the end away from the operator.

[0091] In one embodiment, please refer to Figures 2 to 5 , the proximal end of the bracket elastic arm 2321 is a free end, and the distal end of the bracket elastic arm 2321 is a connecting end. The stopper 2322 is close to the contact portion 23213 and away from the connecting end. When the bracket elastic arm 2321 is deformed, the stopper 2322 is away from the connecting end, which can make the stopper 2322 have a larger range of movement and more easily release the stop on the guide needle holder 25. In some other embodiments, the stopper 2322 can also be composed of the contact portion 23213.

[0092] Specifically, in one embodiment, please refer to Figure 5 and Figure 6 In order to facilitate the design of the structure, the bracket elastic arm 2321 has a set width, and the contact portion 23213 and the stop portion 2322 are arranged or connected at intervals along the circumference of the monitor frame 23.

[0095] The housing 21 has a holding release structure 221, which contacts the unlocking housing holding structure 27 after the housing 21 is pressed, so as to overcome the holding force and release the holding effect of the unlocking housing holding structure 27 on the housing 21, so that the unlocking portion 213 can unlock the locking structure 231. The holding force is within a reasonable range according to the strength of pressing the housing 21. The unlocking housing holding structure 27 releases the holding of the housing 21 after the housing 21 is pressed and the holding force is overcome, so as to prevent accidental touch.

[0096] In one embodiment, please refer to Figure 2 , the unlocking shell holding structure 27 is at the proximal end of the monitor frame 23. This facilitates the interaction between the unlocking shell holding structure 27 and the housing 21. In some other embodiments, the unlocking shell holding structure 27 can also be arranged at the distal end of the housing 21.

[0097] The blocking structure 232 includes a support spring arm 2321 and a blocking portion 2322 on the support spring arm 2321, and the blocking portion 2322 is used to block the guide needle holder 25. The monitor frame 23 includes a frame body 233, one end of the support spring arm 2321 is a free end that can move when the support spring arm 2321 is deformed, and the other end is a connecting end connected to the frame body 233.

[0098] The release structure 221 applies a force to the support elastic arm 2321 to deform the support elastic arm 2321, thereby releasing the blocking relationship between the blocking portion 2322 and the guide needle holder 25. The support elastic arm 2321 forms at least a part of the unlocking shell holding structure 27. The support elastic arm 2321 extends from the distal end to the proximal end of the monitor holder 23. The support elastic arm 2321 maintains the position of the shell 21 by abutting against the shell 21. The shell 21 is deformed by pressing the support elastic arm 2321, and the abutting relationship between the support elastic arm 2321 and the shell 21 is released.

[0099] In one embodiment, please refer to Figures 2 to 5 The support elastic arm 2321 extends from the distal end to the proximal end of the monitor frame 23, and the support elastic arm 2321 maintains the position of the housing 21 by abutting against the housing 21. In some other embodiments, the unlocking shell holding structure 27 may also use a spring sheet in addition to the support elastic arm 2321.

[0100] Further, in one embodiment, please refer to Figure 2 The release structure 214 includes a release arm 215, which is located in the housing 21. The release arm 215 extends from the proximal end of the housing 21 to the distal end of the housing 21. The distal end of the release arm 215 abuts against the proximal end of the bracket elastic arm 2321. The distal end of the release arm 215 and the proximal end of the bracket elastic arm 2321 both have slopes. The slope of the distal end of the release arm 215 is the release arm slope 2151, and the slope of the proximal end of the bracket elastic arm 2321 is the bracket elastic arm slope 23211. The release arm slope 2151 and the bracket elastic arm slope 23211 are used to guide the bracket elastic arm 2321 to deform after the housing 21 is pressed, and release the abutment relationship between the release arm 215 and the bracket elastic arm 2321, thereby releasing the holding effect of the unlocking shell holding structure 27. In one embodiment, the release arm 215 is a rigid arm. In some other embodiments, the bracket elastic arm 2321 and the retaining release arm 215 are both elastic arms.

[0101] In some other embodiments, only the distal end of the holding release arm 215 may have the holding release arm slope 2151, and the proximal end of the bracket elastic arm 2321 may have a plane in contact with the holding release arm slope 2151, and the plane may be perpendicular to the direction of movement of the monitoring instrument frame 23. In some other embodiments, only the proximal end of the bracket elastic arm 2321 may have the bracket elastic arm slope 23211. 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 monitoring instrument frame 23, and the slope may be an inclined surface, an outer convex surface, or an inner concave surface.

[0102] In one embodiment, please refer to Figures 2 to 6 When the support spring arm 2321 releases the abutting relationship with the housing 21, it bends and deforms toward the first side of the support spring arm 2321, and when the blocking relationship with the guide needle holder 25 is released, it bends and deforms toward the second side of the support spring arm 2321. The first side and the second side are two opposite sides of the support spring arm 2321.

[0103] Specifically, in one embodiment, please refer to Figures 2 to 6 The bracket elastic arm 2321 includes an inclined section 23212, and one end surface of the inclined section 23212 is a bracket elastic arm slope 23211. The bracket elastic arm slope 23211 is used to abut against the holding release structure 221 after the housing 21 is pressed, so that the bracket elastic arm 2321 is deformed.

[0104] In one embodiment, please refer to Figure 2In the direction from the distal end of the bracket elastic arm 2321 to the proximal end, the inclined section 23212 gradually inclines toward the distal end of the retaining release arm 215. Thus, when the housing 21 is pressed to make the retaining release arm 215 abut against the bracket elastic arm slope 23211 on the inclined section 23212, a greater force is required to elastically deform the bracket elastic arm 2321, thereby releasing the retaining effect of the bracket elastic arm 2321 on the housing 21.

[0105] In one embodiment, please refer to Figure 2 In order to facilitate unlocking of the monitor rack 23, the minimum force required for the unlocking structure 214 to unlock the unlocking shell holding structure 27 on the housing 21 is the first force, and the minimum force required for the unlocking part 213 to unlock the locking structure 231 on the monitor rack 23 is the second force, and the first force is greater than the second force. This can not only improve the effect of preventing accidental touch, but also unlock the monitor rack 23 more smoothly, and the overall operation is smoother.

[0106] In some other embodiments, according to actual needs, the first force may also be less than or equal to the second force.

[0107] In one embodiment, please refer to Figure 2 and Figure 5 , the number of unlocking shell holding structures 27 is at least two, the number of holding release structures 214 is at least two, the number of unlocking parts 213 is at least two, and the holding release structures 214 and the unlocking parts 213 are arranged alternately in the circumferential direction of the shell 21. Specifically, in one embodiment, the number of holding release arms 215 is more than two, the unlocking part 213 is an unlocking arm 2131, the unlocking arm 2131 extends from the proximal end of the shell 21 to the distal end of the shell 21, the number of unlocking arms 2131 is more than two, and the unlocking arms 2131 and the holding release arms 215 are arranged alternately in the circumferential direction of the shell 21.

[0108] Further, in one embodiment, please refer to Figure 2 The unlocking arm 2131 extends from the proximal end of the housing 21 to the distal end of the housing 21, and the unlocking arm 2131 unlocks the locking structure 231 by abutting against the locking structure 231. The length of the unlocking arm 2131 is not less than the length of the retaining release arm 215. In this way, the unlocking arm 2131 can unlock the locking structure 231 only after the abutting relationship between the retaining release arm 215 and the bracket elastic arm 2321 is released.

[0109] Further, in one embodiment, please refer to Figure 2 and Figure 5The locking structure 231 includes a locking arm 2311, which extends from the distal end to the proximal end of the monitor frame 23. A hook 2312 is provided at the proximal end of the locking arm 2311. The hook 2312 is clamped on the mounting member 22 to achieve locking of the monitor frame 23 and the mounting member 22. The unlocking portion 213 deforms the locking arm 2311 by abutting against the hook 2312, so as to separate the hook 2312 from the mounting member 22.

[0110] For details, please refer to Figure 2 In order to facilitate the unlocking of the hook 2312, a hook slope 2313 is provided on the hook 2312, and an unlocking arm slope is provided at the end of the unlocking arm 2131. Through the cooperation between the unlocking arm slope and the hook slope 2313, a force can be applied to the hook 2312 to separate the hook 2312 from the mounting member 22.

[0111] Further, in one embodiment, please refer to Figures 2 to 5 The mounting member 22 is sleeve-shaped, and the monitor frame 23 is mounted in the mounting member 22. The mounting member 22 can guide the monitor frame 23 to move in a straight line. In this way, the monitor frame 23 can be prevented from rotating, and the monitor frame 23 moves more smoothly.

[0112] In one embodiment, please refer to Figures 2 to 5 The mounting piece 22 is sleeve-shaped. Under the action of the return needle elastic piece 28, the guide needle holder 25 and the monitor frame 23 can be pre-assembled to form a pre-assembled body. The pre-assembled body is inserted into the mounting piece 22 from the distal end of the mounting piece 22, and the implant elastic piece 24 is pressed between the monitor frame 23 and the mounting piece 22.

[0113] Further, in one embodiment, please refer to Figure 5 and Figure 6 The number of the support elastic arms 2321 is at least two, and in the direction from the distal end to the proximal end of the support elastic arm 2321, the inclined section 23212 gradually inclines toward the center line of the guide needle 26. This makes it convenient to insert the support elastic arm 2321 into the mounting member 22.

[0114] In order to further facilitate the installation of the monitoring instrument frame 23, in one embodiment, please refer to Figure 2 In addition to the raised slope 2212, the release protrusion 2211 also has a raised guide slope 2213, and the raised guide slope 2213 is arranged opposite to the raised slope 2212, so that when the monitor frame 23 is installed into the mounting part 22, the raised guide slope 2213 can guide the bracket elastic arm 2321 to be inserted into the mounting part 22.

[0115] Further, in one embodiment, please refer to Figure 2 and Figure 5The housing assembly 20 has a needle holder stop structure 222, which is used to stop the guide needle holder 25 to limit the maximum travel of the guide needle holder 25 toward the operating end. In this way, the range of movement of the guide needle holder 25 can be limited as needed.

[0116] Specifically, in one embodiment, after the lock between the monitor frame 23 and the shell assembly 20 is released, the monitor frame 23 moves toward the human body, and at this time, the stop structure 232 does not contact the guide needle frame 25, until the monitor frame 23 moves a first distance, the stop structure 232 stops the guide needle frame 25, and drives the guide needle frame 25 to move toward the distal end. This movement situation can be applicable to the situation where the needle handle 261 of the guide needle 26 is relatively long, and the needle handle 261 still extends out of the monitor 1 for a section after passing through the monitor 1. The side of the monitor 1 facing the human body is provided with an applicator 12. After the guide needle 26 implants the analyte sensor 11 into the human body, the applicator 12 contacts the human skin 3 and fixes the monitor 1 on the human skin 3. When the guide needle 26 pierces the human body, if the needle handle 261 of the guide needle 26 protrudes from the side of the monitor 1 facing the human body, the needle handle 261 of the guide needle 26 will conflict with the human skin 3, affecting the adhesion of the monitor 1 to the human body. In order to make the monitor 1 stick better to the human skin 3, in one embodiment, the length of the first distance is equal to the length of the needle handle 261 extending from the monitor 1, or the first distance is greater than the length of the needle handle 261 extending from the monitor 1, so that when the guide needle 26 is inserted into the human body, the needle handle 261 is flush with the side of the monitor 1 facing the human body or retracted a certain distance into the monitor 1.

[0117] Further, in one embodiment, please refer to Figure 3 and Figure 6 When the monitor frame 23 is in the initial position, although the stop structure 232 of the monitor frame 23 does not stop the guide needle frame 25, the return needle elastic member 28 is still in a compressed state and is between the guide needle frame 25 and the monitor frame 23, so that the guide needle frame 25 is not easy to shake and has better stability. Relying on the stopping effect of the needle frame stop structure 222, the guide needle frame 25 and the stop structure 232 of the monitor frame 23 are kept in a state of being spaced apart and not in contact.

[0118] Specifically, in one embodiment, please refer to Figure 3 and Figure 6 The needle holder stop structure 222 cooperates with the guide needle holder 25 to keep the return needle elastic member 28 in a compressed state. In one embodiment, the needle holder stop structure 222 is a stop block. In some other embodiments, the needle holder stop structure 222 can also be a stop step or a stop groove.

[0119] In one embodiment, please refer to Figures 2 to 6The needle handle 261 passes through the monitor 1 to install the sensor cap 210, and the sensor cap 210 can be installed on the needle handle 261 by any feasible method such as screwing, snapping, magnetic attraction, etc. The sensor cap 210 can protect the monitor 1 and the analyte sensor 11.

[0120] The housing assembly 20 includes a protective cover 29. A sensor cap 210 is mounted on the portion of the guide needle holder 25 that passes through the monitor 1. The protective cover 29 is fixed on the housing 21. The housing 21 has an opening 212, and the protective cover 29 is mounted at the opening 212.

[0121] In one embodiment, the anti-accidental touch function can be realized by unlocking the shell holding structure 27, and the user does not need to remove the anti-accidental touch parts, which is more convenient for users to use. The shell 21 of the needle assist device acts as a button, and there is no need to add a separate button part, which reduces the manufacturing cost. At the same time, the area of ​​the shell 21 is larger than that of a separate button, which is more convenient for users to use.

[0122] In one embodiment, please refer to Figure 2 The guide needle holder 25 has a claw 251 , and the claw 251 holds the needle handle 261 of the guide needle 26 .

[0123] In one embodiment, please refer to Figures 1 to 6 , the implantation process of the analyte sensor implant device is as follows:

[0124] When it is necessary to implant the analyte sensor 11 into the human body, the protective cover 29 of the analyte sensor implantation device is opened, the sensor cap 210 is removed, and the opening 212 of the shell 21 is directed toward the position where the sensor needs to be implanted in the human body. Pressure is applied to the pressing end 211 of the shell 21 to make the retaining release structure 214 of the shell 21 contact with the unlocking shell retaining structure 27, thereby overcoming the retaining force of the unlocking shell retaining structure 27 on the shell 21, releasing the retaining effect of the unlocking shell retaining structure 27 on the shell 21, and enabling the unlocking portion 213 to unlock the locking structure 231.

[0125] After the monitor frame 23 is unlocked, it moves toward the human body under the action of the implantation elastic member 24, and the blocking structure 232 blocks the guide needle frame 25 in the direction away from the human body, so that when the monitor frame 23 moves toward the implantation position, it can drive the guide needle frame 25 and the guide needle 26 to move in the direction close to the human body, and then drive the guide needle to move in the direction of piercing the human body, so that the guide needle 26 implants the analyte sensor 11 into the human body. After the analyte sensor 11 is implanted into the human body, the guide needle 26 implants the analyte sensor 11 into the human body, and the release structure 221 applies a force to the blocking structure 232, releasing the blocking of the guide needle frame 232 on the guide needle frame 25, and the guide needle frame 25 and the monitor frame 23 can move relative to each other. Under the action of the needle return elastic member 28, the guide needle 26 is withdrawn from the human body. After the implantation of the analyte sensor 11 is completed, the needle aid 2 is removed by operating the housing 21, and the monitor 1 is separated from the monitor frame 23 under the action of the patch 12. The monitor 1 is adhered to the surface of the human body and can monitor the parameters of the human body in real time.
