Description

[0002] The traditional blood glucose measurement method is cumbersome to use, has deep wounds, obvious pain, and can only measure a single value. Diabetic patients cannot understand their glucose levels in real time. In order to understand their glucose levels in real time, some patients choose to wear analyte sensors. The analyte sensor needs to be inserted into the human body using a sharp object (introducer needle) of the implant device so that the analyte sensor contacts the body fluid.

[0003] However, most existing implant devices include two components: a needle aid and a monitor. Users need to assemble the needle aid and the monitor during use, and this assembly process increases the difficulty of use for users. The current implant device requires the user to apply pressure, and the guide needle is inserted under the pressure of the user. After the pressure is released, the guide needle will be pulled out of the human body. During the insertion operation, it is difficult for the user to determine whether the sharp object of the injection device has been inserted into place, which can easily cause the sharp object to be retracted prematurely before the sensor is implanted in the human body.

[0061] 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.

[0062] In one embodiment, please refer to Figures 1 to 6 The analyte sensor implantation device comprises a monitor 1 and an analyte sensor 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.

[0063] The analyte sensor implantation device is used to insert the analyte sensor 11 of the monitor 1 into the human body, and 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.

[0064] In one embodiment, please refer to Figures 1 to 6 The analyte sensor needle aid includes a shell assembly 20, a monitor frame 23, an implant elastic member 24, a guide needle frame 25 arranged on the monitor frame 23, and a guide needle 26 assembled on the guide needle frame 25. The monitor frame 23 is used to install the monitor 1, and the guide needle 26 is used to implant the analyte sensor 11 of the monitor 1 into the human body.

[0065] The monitor frame 23 can be movably mounted in the shell assembly 20, and the monitor frame 23 includes a locking structure 231 for locking the shell assembly 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 assembly 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.

[0066] 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.

[0067] The activity stroke of the monitor frame 23 includes an initial position and an implantation position. In the initial position, the monitor frame 23 is locked by the locking structure 231. In 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, and 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.

[0068] 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.

[0069] The shell assembly 20 further includes a releasing 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 releasing structure 221 releases the blocking of the blocking structure 232 on the guide needle frame 25 .

[0070] The analyte sensor needle aid also includes a return needle elastic member 28, which is used to apply a return needle elastic force to the guide needle holder 25. After the stopping effect of the stopping structure 232 on the guide needle holder 25 is released, the return needle elastic force drives the guide needle holder 25 to extract the guide needle 26.

[0071] The analyte sensor needle aid adopts 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 in a 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 present application completes the insertion of the guide needle 26 by applying elastic force through the implanted elastic member 24, reducing 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.

[0073] 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.

[0074] Further, in one embodiment, please refer to Figures 2 to 5 At 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.

[0077] In one embodiment, please refer to Figures 2 to 5 , 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.

[0080] Furthermore, in one embodiment, the proximal end of the analyte sensor 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.

[0081] 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.

The mounting member 22 and the monitor frame 23 are both movably assembled in the push-to-unlock housing 21. The unlocking portion 213 is on the push-to-unlock housing 21, and the release structure 221 is on the mounting member 22 and / or the push-to-unlock housing 21.

[0084] In one embodiment, please refer to Figures 2 to 5 , the mounting member 22 is movably mounted in the push-to-unlock shell 21. The monitor frame 23 is movably mounted on the mounting member 22, and an unlocking shell holding structure 27 is provided on the monitor frame 23, and the unlocking shell holding structure 27 is used to apply a holding force to the push-to-unlock shell 21 to maintain the position of the push-to-unlock shell 21. 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 structures 27 can be more than two, some of which are on the mounting member 22 and some of which are on the monitor frame 23.

[0085] The push-to-unlock shell 21 has a holding release structure 221, which contacts the unlocking shell holding structure 27 after the push-to-unlock shell 21 is pressed, so as to overcome the holding force and release the holding effect of the unlocking shell holding structure 27 on the push-to-unlock shell 21, so that the unlocking portion 213 can unlock the locking structure 231. The holding force is selected within a reasonable range according to the strength of pressing the push-to-unlock shell 21. After the push-to-unlock shell 21 is pressed and the holding force is overcome, the unlocking shell holding structure 27 releases the holding of the push-to-unlock shell 21, which can prevent accidental touches.

[0086] 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 push-to-unlock shell 21. In some other embodiments, the unlocking shell holding structure 27 can also be arranged at the distal end of the push-to-unlock shell 21.

[0087] 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.

[0088] 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 stopper 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 press-unlock shell 21 by abutting against the press-unlock shell 21. The press-unlock shell 21 is deformed by pressing the support elastic arm 2321, thereby releasing the abutting relationship between the support elastic arm 2321 and the press-unlock shell 21.

[0089] 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 pressing the unlocking shell 21 by pressing against the unlocking shell 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.

[0090] Further, in one embodiment, please refer to Figure 2The release structure 214 includes a release arm 215, which is located in the push-unlock shell 21. The release arm 215 extends from the proximal end of the push-unlock shell 21 to the distal end of the push-unlock shell 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 push-unlock shell 21 is pressed, so as to release the abutting relationship between the release arm 215 and the bracket elastic arm 2321, thereby releasing the holding effect of the unlock 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.

[0091] 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.

[0092] In one embodiment, please refer to Figures 2 to 5 When the support spring arm 2321 releases the abutting relationship with the press-unlocking shell 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.

[0093] Specifically, in one embodiment, please refer to Figures 2 to 5 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 push-to-unlock shell 21 is pressed, so that the bracket elastic arm 2321 is deformed.

[0094] 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 hold release arm 215. In this way, when the push-to-unlock shell 21 is pressed to make the hold 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 holding effect of the bracket elastic arm 2321 on the push-to-unlock shell 21.

[0095] In one embodiment, please refer to Figure 2 In order to facilitate unlocking of the monitor rack 23, the minimum force required for the release structure 214 to release the unlocking shell holding structure 27 from holding the unlocking shell 21 is the first force, and the minimum force required for the unlocking part 213 to release the locking structure 231 from locking 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.

[0096] In some other embodiments, according to actual needs, the first force may also be less than or equal to the second force.

[0097] In one embodiment, please refer to Figure 2 and Figure 5 , the number of the unlocking shell holding structures 27 is at least two, the number of the holding release structures 214 is at least two, the number of the unlocking parts 213 is at least two, and the holding release structures 214 and the unlocking parts 213 are alternately arranged in the circumferential direction of the push-to-unlock shell 21. Specifically, in one embodiment, the number of the 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 push-to-unlock shell 21 to the distal end of the push-to-unlock shell 21, the number of the unlocking arms 2131 is more than two, and the unlocking arms 2131 and the holding release arms 215 are alternately arranged in the circumferential direction of the push-to-unlock shell 21.

[0098] Further, in one embodiment, please refer to Figure 2 The unlocking arm 2131 extends from the proximal end of the push-unlocking shell 21 to the distal end of the push-unlocking shell 21, and the unlocking arm 2131 unlocks by abutting against the locking structure 231, and the length of the unlocking arm 2131 is not less than the length of the holding release arm 215. In this way, the unlocking arm 2131 can unlock the locking structure 231 only after the abutting relationship between the holding release arm 215 and the bracket elastic arm 2321 is released.

[0099] 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.

[0100] 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.

[0101] Further, in one embodiment, please refer to Figures 2 to 4 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.

[0102] In one embodiment, please refer to Figures 2 to 4 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.

[0103] Further, in one embodiment, please refer to Figure 5 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.

[0104] 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.

[0105] 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.

[0106] 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 adhesive sheet 12. After the guide needle 26 implants the analyte sensor 11 into the human body, the adhesive sheet 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.

[0107] Further, in one embodiment, please refer to Figure 5 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.

[0108] Specifically, in one embodiment, please refer to Figure 5 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.

[0109] In one embodiment, please refer to Figures 2 to 6The needle handle 261 passes through the monitor 1 to install the sensor cap 210. 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.

[0110] The housing assembly 20 includes a protective cover 29, a sensor cap 210 mounted on the portion of the guide needle holder 25 passing through the monitor 1, and the protective cover 29 is fixed on the push-to-unlock housing 21. The push-to-unlock housing 21 has an opening 212, and the protective cover 29 is mounted at the opening 212.

[0111] In one embodiment, the unlocking shell holding structure 27 can realize the anti-accidental touch function, and the user does not need to remove the anti-accidental touch parts, which is more convenient for users to use. The push-to-unlock shell 21 of the needle aid 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 push-to-unlock shell 21 is larger than that of a separate button, which is more convenient for users to use.

[0112] 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 .

[0113] In one embodiment, please refer to Figure 6 and Figure 7 The monitor frame 23 is provided with a magnet 234. The monitor 1 includes a battery 13. The monitor 1 is fixed to the monitor frame 23 by adsorbing the battery shell of the battery 13 and the magnet 234. After the adhesive sheet 12 is attached to the human body, the adhesive force of the adhesive sheet 12 is greater than the magnetic attraction force. When the biosensor needle aid is removed, the monitor 1 is separated from the monitor frame 23.

[0114] In one embodiment, please refer to Figures 1 to 6 The implantation process of the analyte sensor 11 implantation device is as follows:

[0115] When it is necessary to implant the analyte sensor 11 into the human body, the protective cover 29 of the analyte sensor 11 implantation device is opened, and the sensor cap 210 is removed, so that the opening 212 of the push-to-unlock shell 21 is facing the position where the sensor needs to be implanted in the human body, and pressure is applied to the pressing end 211 of the push-to-unlock shell 21, so that the retaining release structure 214 of the push-to-unlock shell 21 contacts the unlocking shell retaining structure 27, thereby overcoming the retaining force of the unlocking shell retaining structure 27 on the push-to-unlock shell 21, releasing the retaining effect of the unlocking shell retaining structure 27 on the push-to-unlock shell 21, and enabling the unlocking portion 213 to unlock the locking structure 231.

[0116] 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 analyte sensor needle aid 2 is removed by pressing the unlocking shell 21. Under the action of the adhesive sheet 12, the monitor 1 is separated from the monitor frame 23. The monitor 1 is adhered to the surface of the human body and can monitor the parameters of the human body in real time.
