Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a biosensor implantation device and a biosensor needle aid. Background Technology

[0002] Traditional blood glucose measurement methods are cumbersome, involve deep incisions, cause significant pain, and can only measure a single value, preventing diabetic patients from understanding their glucose levels in real time. To gain real-time access to their glucose levels, some patients choose to wear biosensors. Biosensors require a sharp implant (guide needle) to insert into the body, allowing the biosensor to come into contact with bodily fluids.

[0003] However, most existing implantation devices consist of two components: a needle applicator and a monitoring device. Users need to assemble these two components, which increases the difficulty of use. Current implantation devices rely on user pressure to insert the guide needle, which is then withdrawn after the pressure is released. During insertion, it's difficult for users to determine if the sharp part of the device has been properly inserted, potentially causing it to retract prematurely before the sensor is implanted. To address this issue, current needle applicators typically include an unlocking shell, a mounting component, and an implantation drive frame that drives the guide needle into the body. An implantation elastic element is installed between the mounting component and the implantation drive frame, applying elastic force to insert the guide needle, reducing the required manual force. However, after use, the mounting component remains exposed, and the protective shell offers limited protection. Utility Model Content

Detailed Implementation

[0053] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0054] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0055] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include direct connection, indirect connection, and contact connection (linkage).

[0056] In one embodiment, please refer to Figures 1 to 7 The biosensor implantation device includes a monitor 1 and a biosensor needle 2. The monitor 1 includes a biosensor 11. The monitor 1 can be an instrument used to monitor human physiological parameters.

[0057] The biosensor implantation device is used to insert the biosensor 11 of the monitor 1 into the human body. The biosensor 11 is typically implanted into the human body with the aid of a guide needle 26. The monitor 1 and the biosensor 11 can adopt any feasible existing structure. For example, the biosensor 11 can be a sensor for detecting human blood glucose, and the monitor 1 can be an instrument for monitoring human blood glucose.

[0058] In one embodiment, please refer to Figures 1 to 7 The biosensor implanter 2 includes a press-to-unlock housing 21, a mounting component 22, a guide needle 26 for implanting the biosensor into the human body, an implantation drive frame 23 for driving the guide needle 26, and an implantation elastic member 24 for applying elastic force to the implantation drive frame 23. The proximal end of the press-to-unlock housing 21 is a press end 211 for press operation, and the distal end has an opening 212 for facing the human body. Both the mounting component 22 and the implantation drive frame 23 are movably mounted within the press-to-unlock housing 21. The implantation elastic member 24 is located between the implantation drive frame 23 and the mounting component 22, and applies an elastic force to the implantation drive frame 23 to move it distally.

[0059] The guide pin 26 is mounted on the implantation drive frame 23. The implantation drive frame 23 includes a locking structure 231, which is used to lock the mounting member 22 to the implantation drive frame 23. Before using the biosensor implantation device, the relative positions of the implantation drive frame 23 and the mounting member 22 are locked and cannot move relative to each other. When the biosensor 11 needs to be implanted into the human body, the locking structure 231 needs to be unlocked.

[0060] The press-to-unlock shell 21 has an unlocking part 213, which is used to release the locking function of the locking structure 231. The unlocking part 213 is used to contact the locking structure 231 to release the locking function of the locking structure 231 on the implant drive frame 23, so that the implant drive frame 23 moves distally under the elastic force of the implant elastic member 24, that is, moves relative to the mounting member 22 toward the human body. It should be noted that the press-to-unlock shell can be in the form of a whole movement, or it can include a shell and an unlocking part that can move relative to the shell. The unlocking part can be a button that moves relative to the shell. When unlocking is needed, the button can be pressed.

[0061] Please refer to Figure 2 and Figure 7 The distal end of the mounting piece 22 is used to extend the press-to-unlock shell 21 before the locking structure 231 is unlocked and to contact the human skin 3. After the press-to-unlock shell 21 is pressed to unlock the locking structure 231, and the implantation drive frame 23 drives the guide needle 26 to implant the biosensor 11, the mounting piece 22 retracts the press-to-unlock shell 21 and disengages from the human skin 3 under the action of the implantation elastic member 24.

[0062] When the press-to-unlock shell 21 of this application is pressed, the locking structure 231 is unlocked. Under the action of the implanted elastic element 24, the mounting part 22 retracts into the press-to-unlock shell 21, thus providing better protection for the mounting part 22 by pressing the press-to-unlock shell 21.

[0063] It should be noted that the guide needle 26 can be directly mounted on the implantation drive frame 23, or it can be mounted on the implantation drive frame 23 using other parts. For example, in one embodiment, the implantation drive frame 23 includes a guide needle holder 25 and a monitor holder 230, with the monitor holder 230 used to mount the monitor 1. The guide needle 26 is mounted on the guide needle holder 25, and the guide needle holder 25 is mounted on the monitor holder 230. The locking structure 231 is used to lock the monitor holder 230 to the mounting component 22. When the monitor holder 230 moves distally under the action of the implantation elastic member 24, the guide needle holder 25 also moves distally. The guide needle 26 is mounted on the guide needle holder 25 and is used to implant the biosensor 11 of the monitor 1 into the human body.

[0064] Furthermore, in one embodiment, please refer to Figures 2 to 4 The mounting component 22 is a mounting sleeve, and the implantation drive frame 23 is installed inside the mounting component 22. The mounting component 22 can guide the implantation drive frame 23 to move in a straight line. This can prevent the implantation drive frame 23 from rotating, and the movement of the implantation drive frame 23 is smoother.

[0065] In one embodiment, please refer to Figure 6The pressing unlock shell 21 includes a first stop structure 216 and a second stop structure 214. When the locking structure 231 is in the locked state: the first stop structure 216 engages with the mounting member 22, restricting the mounting member 22 from moving distally; the second stop structure 214 engages with the implant drive frame 23, restricting the implant drive frame 23 from moving proximally. Thus, with the locking structure 231 locked, the positions of the mounting member 22 and the implant drive frame 23 are stable and not easily shifted.

[0066] Furthermore, in one embodiment, please refer to Figure 2 and Figure 6 The implanted drive frame 23 includes an unlocking shell retaining structure 27, which applies a retaining force to the pressed unlocking shell 21 to maintain its position. A second stop structure 214 contacts the unlocking shell retaining structure 27 after the unlocking shell 21 is pressed, overcoming the retaining force and releasing the retaining force of the unlocking shell retaining structure 27 from holding the pressed unlocking shell 21, allowing the unlocking part to unlock the locking structure 231. The magnitude of the retaining force is selected within a reasonable range based on the force applied to pressing the unlocking shell 21. The unlocking shell retaining structure 27 releases its hold on the pressed unlocking shell 21 after the retaining force is overcome, thus preventing accidental activation.

[0067] The anti-accidental touch function is achieved by using the unlocking shell retaining structure 27, eliminating the need for users to disassemble the anti-accidental touch components and making it more convenient for users. In one embodiment, the press-to-unlock shell 21 functions as a button, eliminating the need for a separate button component, reducing manufacturing costs. Furthermore, the press-to-unlock shell 21 has a larger area than a separate button, making it even more convenient for users. Alternatively, in one embodiment, the unlocking part of the press-to-unlock shell 21 is a button that can move relative to the shell.

[0068] It should be noted that in this application, the terms "proximal end" and "far end" are described based on the operator's operating position, where the proximal end is the end closer to the operator and the distal end is the end farther from the operator.

[0069] In one embodiment, please refer to Figure 2 The unlocking shell retaining structure 27 is located at the proximal end of the implanted drive frame 23. This facilitates the interaction between the unlocking shell retaining structure 27 and the press-to-unlock shell 21. In some other embodiments, the unlocking shell retaining structure 27 may also be located at the distal end of the press-to-unlock shell 21. Specifically, in one embodiment, the unlocking shell retaining structure 27 is located on the monitoring device frame 230.

[0070] Furthermore, in one embodiment, please refer to Figures 2 to 4The unlocking shell retaining structure 27 includes a retaining arm 271 that extends proximally from the distal end of the implanted drive frame 23. The retaining arm 271 retains the position of the pressed unlocking shell 21 by abutting against it. In some other embodiments, the retaining arm 271 extends proximally from the distal end of the monitoring frame 230.

[0071] Furthermore, in one embodiment, please refer to Figure 2 and Figure 6 The second stop structure 214 includes a retaining release arm 215, which is located within the press-to-unlock housing 21. The retaining release arm 215 extends from the proximal end to the distal end of the press-to-unlock housing 21, with the distal end of the retaining release arm 215 abutting against the proximal end of the retaining arm 271. At least one of the retaining arm 271 and the retaining release arm 215 is a spring arm. Both the distal end of the retaining release arm 215 and the proximal end of the retaining arm 271 have abutting slopes. The abutting slope of the distal end of the retaining release arm 215 is the retaining release arm slope 2151, and the abutting slope of the proximal end of the retaining arm 271 is the retaining arm slope 2711. Both the retaining release arm slope 2151 and the retaining arm slope 2711 are used to guide the spring arm to deform after the press-to-unlock housing 21 is pressed, thereby releasing the abutting relationship between the retaining release arm 215 and the retaining arm 271, and thus releasing the retaining function of the unlock housing retaining structure 27. In one embodiment, please refer to... Figure 2 The retaining arm 271 is a spring arm, and the retaining release arm 215 is a rigid arm. In some other embodiments, the retaining arm 271 is a rigid arm, and the retaining release arm 215 is a spring arm. In some other embodiments, both the retaining arm 271 and the retaining release arm 215 are spring arms.

[0072] In some other embodiments, only the distal end of the holding and releasing arm 215 may have a holding and releasing arm slope 2151, while the proximal end of the holding arm 271 may have a plane that contacts the holding and releasing arm slope 2151, the plane being perpendicular to the direction of movement of the implantation drive frame 23. In some other embodiments, only the proximal end of the holding arm 271 may have a holding arm slope 2711. It should be noted that, in this application, a slope refers to a surface with a certain gradient in the direction of movement of the implantation drive frame 23; the slope can be an inclined surface, a convex surface, or a concave surface.

[0073] In one embodiment, please refer to Figures 2 to 5To improve the anti-accidental activation effect, the retaining arm 271 includes an inclined section 2712, which abuts against the retaining release arm 215. One end face of the inclined section 2712 is the retaining arm slope 2711. In the direction from the distal end to the proximal end of the retaining arm 271, the inclined section 2712 gradually slopes towards the distal end of the retaining release arm 215. Thus, when pressure is applied to the pressing unlock housing 21 to make the retaining release arm 215 abut against the retaining arm slope 2711 on the inclined section 2712, a larger force is required to cause the retaining arm 271 to elastically deform, thereby releasing the retaining arm 271 from the pressing unlock housing 21.

[0074] In one embodiment, please refer to Figure 2 To facilitate the release of the implant drive frame 23 from its lock, the second stop structure 214 releases the minimum force required by the unlocking shell retaining structure 27 to hold the unlocking shell 21, which is the first force. The unlocking part 213 releases the minimum force required by the locking structure 231 to lock the implant drive frame 23, which is the second force. The first force is greater than the second force. This improves the prevention of accidental touches and allows for smoother unlocking of the implant drive frame 23, resulting in a more fluid overall operation.

[0075] In some other embodiments, the first force may be less than or equal to the second force, depending on actual needs.

[0076] In one embodiment, please refer to Figure 2 and Figure 5 The number of unlocking shell retaining structures 27 is at least two, the number of second stop structures 214 is at least two, and the number of unlocking parts 213 is at least two. The second stop structures 214 and unlocking parts 213 are arranged alternately in the circumferential direction of the pressed unlocking shell 21. Specifically, in one embodiment, the number of retaining release arms 215 is two or more, and the unlocking part 213 is an unlocking arm 2131. The unlocking arm 2131 extends from the proximal end of the pressed unlocking shell 21 to the distal end of the pressed unlocking shell 21. The number of unlocking arms 2131 is two or more, and the unlocking arm 2131 and retaining release arms 215 are arranged alternately in the circumferential direction of the pressed unlocking shell 21.

[0077] Furthermore, in one embodiment, please refer to Figure 2 The unlocking arm 2131 extends from the proximal end of the press-unlock housing 21 to the distal end of the press-unlock housing 21. The unlocking arm 2131 unlocks the housing by abutting against the locking structure 231. The length of the unlocking arm 2131 is not less than the length of the holding release arm 215. This ensures that the abutting relationship between the holding release arm 215 and the holding arm 271 is released before the unlocking arm 2131 unlocks the locking structure 231.

[0078] In one embodiment, please refer to Figure 6The implantation drive frame 23 has an implantation position. When the implantation drive frame 23 is in the implantation position, the guide needle 26 implants the biosensor 11 into the human body. The press-to-unlock shell 21 has a third stop structure 217, which is used to stop the implantation drive frame 23 when it moves to the implantation position, thus restricting the implantation drive frame 23 from moving distally.

[0079] Specifically, in one embodiment, please refer to Figure 6 The third stop structure 217 is a stop protrusion 2171 located on the inner wall of the press-to-unlock shell 21. In one embodiment, please refer to... Figure 6 When the implantation drive frame 23 is in the implantation position, the monitor frame 230 engages with the stop protrusion 2171. The monitor frame 230 passes through the mounting frame and engages with the stop protrusion 2171. The monitor frame 230 includes a stop arm 233 extending from the distal end to the proximal end, with the proximal end of the stop arm 233 being a free end. The proximal end of the stop arm 233 has a stop hook 2331 for engaging with the stop protrusion 2171.

[0080] Furthermore, in one embodiment, the press-to-unlock shell 21 has a fourth stop structure, which is used to stop the implantation drive frame 23 from moving to the implantation position and restrict the proximal movement of the implantation member 22. In one embodiment, the fourth stop structure is the inner wall surface of the proximal end of the press-to-unlock shell 21.

[0081] Furthermore, in one embodiment, please refer to Figure 2 and Figure 5 Specifically, in one embodiment, the locking structure 231 is used to lock the mounting member 22 to the monitoring device frame 230. In one embodiment, the locking structure 231 includes a locking arm 2311, which extends from the distal end to the proximal end of the implantation drive frame 23, and a hook 2312 is provided at the proximal end of the locking arm 2311. The hook 2312 engages with the mounting member 22, thereby locking the implantation drive frame 23 to the mounting member 22. The unlocking part 213 deforms the locking arm 2311 by abutting against the hook 2312, thereby separating the hook 2312 from the mounting member 22.

[0082] Specifically, in one embodiment, please refer to Figure 2 and Figure 5 The locking arm 2311 is located on the monitoring device frame 230.

[0083] In one embodiment, please refer to Figure 2 In order to facilitate the unlocking of the hook 2312, the hook 2312 is provided with a 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 hook slope 2313, a force can be applied to the hook 2312 to separate the hook 2312 from the mounting part 22.

[0084] Furthermore, in one embodiment, please refer to Figures 2 to 4 The implanted elastic element 24 is a spring, which is clamped between the monitor frame 230 and the mounting part 22. After the lock between the monitor frame 230 and the mounting part 22 is released, the monitor frame 230 moves towards the human body under the action of the spring, causing the guide needle holder 25 and the guide needle 26 to pierce the human skin 3. 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 part 22 and is in a compressed state.

[0085] In one embodiment, please refer to Figure 2 A return needle elastic element 28 is provided between the implantation drive frame 23 and the guide needle frame 25. After the biosensor 11 is implanted into the human body, the guide needle frame 25 and the implantation drive frame 23 can move relative to each other. Under the action of the return needle elastic element 28, the guide needle 26 is withdrawn from the human body. The part of the monitor 1 that contacts the human body is provided with an adhesive sheet 12. Under the action of the adhesive sheet 12, the monitor 1 separates from the implantation drive frame 23, and the monitor 1 remains on the surface of the human skin 3. After the implantation of the biosensor 11 is completed, the biosensor needle aid 2 can be removed by pressing the unlocking shell 21. The monitor 1 is attached to the surface of the human body and can monitor the human body parameters in real time.

[0086] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The monitoring device frame 230 also includes a blocking structure 232, which blocks the guide needle frame 25 in a direction away from the human body, so that when the monitoring device frame 230 moves toward the implantation position, it can drive the guide needle frame 25 to move toward the human body, thereby driving the guide needle to move toward the direction of needle insertion into the human body.

[0087] The mounting component 22 also includes a release structure 221. When the monitor frame 230 moves to the implantation position, the guide needle 26 implants the biosensor 11 into the human body. The release structure 221 applies a force to the stop structure 232, releasing the stop structure 232 from blocking the guide needle frame 25. The return needle elastic element 28 applies a return needle force to the guide needle frame 25. After the stop structure 232 is released from blocking the guide needle frame 25, the return needle force drives the guide needle frame 25 to withdraw the guide needle 26.

[0088] In one embodiment, please refer to Figures 2 to 4 The return needle elastic element 28 is located between the guide needle holder 25 and the monitor holder 230 and is always in a compressed state. In one embodiment, the implanted elastic element 24 is located between the mounting member 22 and the monitor holder 230 and is always in a compressed state. In one embodiment, both the return needle elastic element 28 and the implanted elastic element 24 are helical springs. Helical springs have a simple structure and are easy to install.

[0089] Regarding the form of the blocking structure 232, in one embodiment, please refer to... Figure 4 and Figure 5 The retaining arm 271 forms at least a portion 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.

[0090] 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, the release protrusion 2211 having a raised slope 2212 for engaging with the retaining arm 271 to elastically deform the retaining arm 271 away from the release protrusion 2211.

[0091] In one embodiment, please refer to Figure 2 Both the monitor 1 and the biosensor 11 are built into the biosensor needle aid 2. To protect the monitor 1 and the biosensor 11, the biosensor needle aid 2 includes a protective cover 29 and a sensor cap 210. The sensor cap 210 is installed on the portion of the guide needle holder 25 that passes through the monitor 1, and the protective cover 29 is fixed to the press-to-unlock shell 21. The press-to-unlock shell 21 has an opening 212, and the protective cover 29 is installed at the opening 212.

[0092] In one embodiment, please refer to Figure 6 and Figure 7 The monitor holder 230 is equipped with a magnet 234. The monitor 1 includes a battery 13. The battery casing of the battery 13 is attracted to the magnet 234, thus fixing the monitor 1 to the monitor holder 230. 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 is removed, the monitor 1 separates from the monitor holder 230.

[0093] In one embodiment, please refer to Figures 1 to 7 The implantation process of the biosensor 11 implantation device is as follows:

[0094] When it is necessary to implant the biosensor 11 into the human body, open the protective cover 29 of the biosensor 11 implantation device, remove the sensor cap 210, and make the opening 212 of the press-to-unlock shell 21 face the position of the human body where the sensor needs to be implanted. Make the distal end of the mounting piece 22 stick to the skin 3 of the human body, apply pressure to the pressing end 211 of the press-to-unlock shell 21, so that the second stop structure 214 of the press-to-unlock shell 21 contacts the unlock shell retaining structure 27, overcome the holding force of the unlock shell retaining structure 27 on the press-to-unlock shell 21, release the holding effect of the unlock shell retaining structure 27 on the press-to-unlock shell 21, and enable the unlocking part 213 to unlock the locking structure 231. After the implantation drive frame 23 is unlocked, it moves toward the human body under the action of the implantation elastic element 24. The monitor frame 230 drives the guide needle frame 25 and guide needle 26 to move, and the guide needle 26 implants the biosensor 11 into the human body. The mounting part 22 retracts into the press-unlock shell 21. The fourth stop structure stops the mounting part 22, and the stop protrusion 2171 stops the monitor frame 230, preventing the monitor frame 230 from coming out of the press-unlock shell 21.

[0095] After the biosensor 11 is implanted in the human body, the guide needle holder 25 can move relative to the monitor holder 230. Under the action of the return needle elastic element 28, the guide needle 26 is pulled out from the human body. After the implantation of the biosensor 11 is completed, the biosensor needle aid 2 is removed by pressing the unlocking shell 21. Under the action of the adhesive sheet 12, the monitor 1 separates from the implantation drive frame 23. The monitor 1 is attached to the surface of the human body and can monitor the parameters of the human body in real time.

[0096] In one embodiment of a biosensor needle aid, the structure of the biosensor needle aid is the same as that of any of the above embodiments, and will not be described again.

[0097] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
