Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical monitoring equipment, in particular to a biological sensor implanting device. BACKGROUND

[0002] Diabetes is a metabolic disease characterized by high blood sugar. Long-term high blood sugar can easily lead to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. Diabetes is mainly caused by genetic and environmental factors, and is divided into type 1 diabetes and type 2 diabetes. At present, there is no cure for diabetes, but through various treatment methods, diabetes can be well controlled, mainly including five aspects: diabetes patient education, self-monitoring of blood glucose, diet therapy, exercise therapy and drug therapy. Through self-monitoring, diet or drug therapy is the treatment method adopted by most diabetes patients.

[0003] Therefore, a monitor for realizing the function of patient self-monitoring is emerging. At present, patient self-monitoring of blood glucose is mainly through the method of fingertip puncture to monitor blood glucose, but this method lacks operational convenience and comfort. A continuous blood glucose monitor realizes the purpose of continuous monitoring of blood glucose value by implanting a biological sensor in the skin of a recipient. Although the existing implantable sensor can achieve the purpose of implanting a biological sensor in the skin of a recipient, it still has shortcomings in implantation speed and stability, and the operation is relatively cumbersome, which increases the pain and inconvenience of patients, and also has certain danger. SUMMARY

[0004] The present application provides a biological sensor implanting device, which aims to increase the speed and stability of implanting a biological sensor into human skin and improve user experience.

[0005] The biological sensor implanting device of the present application comprises a shell, a trigger mechanism and a lever puncture mechanism. The shell is provided with a first limiting portion, a second limiting portion and a rotation space, the trigger mechanism is installed on the shell, the lever puncture mechanism comprises a lever and a bracket assembly, the lever and the bracket assembly are rotationally connected, the bracket assembly is connected with the shell through a first moving pair, the trigger mechanism can drive the lever puncture mechanism to move relative to the shell, the movement of the lever puncture mechanism comprises a first state and a second state, in the first state, the first end of the lever is driven by the trigger mechanism, so that the lever puncture mechanism moves towards the skin, the first limiting portion limits the rotation of the lever relative to the bracket assembly, the second end of the lever is provided with a needle, the needle is provided with a biological sensor, in the second state, the first end of the lever is moved to the rotation space by the first limiting portion, the second limiting portion limits the movement of the bracket assembly relative to the shell, the lever rotates relative to the bracket assembly, and the second end of the lever drives the needle to separate from the skin.

[0006] The user can place the biosensor implant device of the present application on the user's skin, and the user can activate the trigger mechanism on the shell, which provides the force to drive the lever puncture mechanism to move. The movement process of the lever puncture mechanism includes a first state and a second state. In the first state, through the first moving pair, the lever puncture mechanism can drive the needle to penetrate the user's skin directly relative to the shell, and place the biosensor inside the needle into the user's body to monitor the user's physiological state. In the second state, the lever puncture mechanism drives the needle out of the skin. The lever puncture mechanism of the present application includes a lever and a bracket assembly. The lever can rotate relative to the bracket assembly, but in the first state, the first end of the lever is restricted by the first limit portion of the shell, and the lever cannot rotate relative to the bracket assembly. Therefore, the needle set at the second end of the lever will penetrate the user's skin directly. Due to inertia, the lever puncture mechanism continues to move toward the skin, and the first end of the lever breaks away from the limiting effect of the first limiting portion and moves into the rotation space, allowing the lever to rotate. Then, the bracket assembly is restricted by the second limiting portion of the shell, and the lever puncture mechanism stops moving toward the skin. The needle moves to the deepest part of the skin, while the first end of the lever continues to be driven by the trigger mechanism. The driving force of the trigger mechanism causes the lever to rotate relative to the bracket assembly. The second end of the lever moves in the opposite direction of the first end of the lever relative to the shell, and the second end of the lever drives the needle out of the skin. The biosensor implant device of the present application can continuously complete the action of inserting and removing the needle from the skin in a short period of time, implanting the biosensor into the user's body, and reducing the user's pain. Secondly, the biosensor implant device of the present application utilizes the rotation principle of the lever and only requires a unidirectional driving force to continuously achieve the first state and the second state.

[0097] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0098] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0100] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0101] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0102] This application provides a biosensor implant device that can be used in the field of medical monitoring equipment technology to implant the biosensor into the human body to monitor the physiological status indicators of the human body. Figures 1-6 As shown, the biosensor implantation device of the present application includes a shell 1, a trigger mechanism 3 and a lever puncture mechanism 2. The shell 1 is provided with a first limiting portion 11, a second limiting portion 12 and a rotation space 13. The trigger mechanism 3 is installed on the shell 1. The lever puncture mechanism 2 includes a lever 21 and a bracket assembly 22. The lever 21 and the bracket assembly 22 are rotatably connected. The bracket assembly 22 is connected to the shell 1 through a first moving pair. The trigger mechanism 3 can drive the lever puncture mechanism 2 to move relative to the shell 1. The movement of the lever puncture mechanism 2 includes a first state and a second state.

[0103] In the first state, the first end 21a of the lever 21 is driven by the trigger mechanism 3, causing the lever puncture mechanism 2 to move toward the skin. The first limiter 11 restricts the lever 21 from rotating relative to the bracket assembly 22. The second end 21b of the lever 21 is mounted with a needle 23, which is mounted with a biosensor (not shown).

[0104] In the second state, the first end 21a of the lever 21 moves from the first limiting portion 11 to the rotation space 13, the second limiting portion 12 limits the movement of the bracket assembly 22 relative to the shell 1, the lever 21 rotates relative to the bracket assembly 22, and the second end 21b of the lever 21 drives the needle 23 out of the skin.

[0105] In this embodiment, a user can place the biosensor implant device of the present application on the user's skin and activate the trigger mechanism 3 on the housing 1, which provides the force to drive the lever puncture mechanism 2. The movement of the lever puncture mechanism 2 includes a first state and a second state. In the first state, the lever puncture mechanism 2, through the first moving pair, can drive the needle 23 relative to the housing 1 to penetrate the user's skin directly, placing the biosensor inside the needle 23 in the user's body to monitor the user's physiological condition. In the second state, the lever puncture mechanism 2 drives the needle 23 away from the skin. The lever puncture mechanism 2 of the present application includes a lever 21 and a bracket assembly 22. The lever 21 is capable of rotating relative to the bracket assembly 22. However, in the first state, the first end 21a of the lever 21 is restricted by the first limit portion 11 of the housing 1, preventing the lever 21 from rotating relative to the bracket assembly 22. Therefore, the needle 23 disposed at the second end 21b of the lever 21 penetrates the user's skin directly. Due to inertia, the lever puncture mechanism 2 continues to move toward the skin, and the first end 21a of the lever 21 breaks away from the limiting effect of the first limiting portion 11 and moves to the rotation space 13, so that the lever 21 has the conditions for rotation. Then the bracket assembly 22 is restricted by the second limiting portion 12 of the shell 1, and the lever puncture mechanism 2 does not continue to move toward the skin. The needle 23 moves to the deepest part of the skin, and the first end 21a of the lever 21 continues to be driven by the trigger mechanism 3. The driving force of the trigger mechanism 3 causes the lever 21 to rotate relative to the bracket assembly 22. The second end 21b of the lever 21 moves in the opposite direction to the first end 21a of the lever 21 relative to the shell 1, and the second end 21b of the lever 21 drives the needle 23 to break away from the skin.

[0106] The biosensor implant device of the present application can continuously complete the actions of inserting and withdrawing the needle 23 from the skin in a short period of time, implanting the biosensor into the user's body and reducing the user's pain. Secondly, the biosensor implant device of the present application utilizes the rotation principle of the lever 21, and can continuously achieve the first state and the second state using only a unidirectional driving force. This can simplify the trigger mechanism 3 used to provide the driving force, making the biosensor implant device of the present application more reliable.

[0107] Among them, the biosensor can monitor the user's physiological status indicators such as blood sugar, blood pressure, blood oxygen, pH, etc. In the subsequent introduction of the biosensor implant device of this application, the biosensor is mainly introduced as a sensor that can monitor blood sugar indicators.

[0108] In a specific embodiment, please refer to Figure 6As shown, the first limiting portion 11 is provided on the first plane of the shell 1, the rotation space 13 is provided on the first recessed portion of the shell 1, and the second limiting portion 12 is provided on the shell 1. The limiting protrusion is provided on the shell 1; in the first state, the first end 21a of the lever 21 abuts against the first plane, and in the second state, the first end 21a of the lever 21 moves in the first recessed portion, and the limiting protrusion abuts against the bracket assembly 22.

[0109] In this embodiment, under the driving action of the trigger mechanism 3, the first end 21a of the lever 21 abuts against the first plane and slides along the first plane, limiting the rotation of the lever 21 relative to the bracket assembly 22. When the first end 21a of the lever 21 moves from the first plane to the first recessed portion, the first end 21a of the lever 21 is disengaged from the limiting effect of the first plane, and then the limiting protrusion abuts against the bracket assembly 22. The bracket assembly 22 cannot continue to move toward the skin, and the needle 23 penetrates the deepest part of the skin. At this time, the first state ends, and the lever puncture mechanism 2 begins to enter the second state. The first end 21a of the lever 21 continues to be driven by the trigger mechanism 3, and the first end 21a of the lever 21 rotates in the first recessed portion and approaches the user's skin, while the second end 21b of the lever 21 drives the needle 23 out of the skin.

[0110] The structures of the first plane, the limiting protrusion and the first recessed portion in the biosensor implant device of the present application are simple, and only the corresponding structures need to be processed and manufactured on the shell 1. It is highly economical and can be mass-produced.

[0111] The housing 1 with the first plane, the limiting protrusion and the first recessed portion can be manufactured in an integrated molding manner.

[0112] For details, please refer to Figure 6-Figure 7 As shown, the lever puncture mechanism 2 also includes a needle seat 24, and the needle 23 is installed on the needle seat 24. The needle seat 24 is connected to the second end 21b of the lever 21 through a second movable pair and a rotating pair, and the needle seat 24 is connected to the bracket assembly 22 through a third movable pair.

[0113] In this embodiment, needle 23 is mounted on needle hub 24, which is connected to support assembly 22 via a third movable joint. This allows for freedom of movement between needle hub 24 and support assembly 22. When driven by an external force, needle hub 24 can move directional relative to support assembly 22, allowing needle 23 to be stably removed from the skin and reducing pain for the user. Needle hub 24 is connected to second end 21b of lever 21 via a second movable joint and a rotational joint. This allows for both movement and rotational freedom between needle hub 24 and lever 21, enabling rotational movement of lever 21 to drive directional movement of needle hub 24 within support assembly 22.

[0114] More specifically, please refer to Figure 6-Figure 8As shown, the needle seat 24 is provided with a circular platform 241, the second end 21b of the lever 21 is provided with a second sliding groove 211, the support assembly 22 is provided with a third sliding groove 221, the circular platform 241 is arranged in the second sliding groove 211, and at least part of the circular platform 241 is located in the third sliding groove 221.

[0115] In this embodiment, the circular platform 241 can move and rotate in the second sliding groove 211, and the circular platform 241 can also move in the third sliding groove 221, which is simple in structure and easy to manufacture and assemble.

[0116] In this embodiment, the needle seat 24 is provided with two oppositely arranged circular platforms 241, the second end 21b of the lever 21 is provided with two oppositely arranged second sliding grooves 211, and the support assembly 22 is provided with two oppositely arranged third sliding grooves 221, so that the needle head 23 can be oriented to separate from the skin and reduce the pain of the user.

[0117] Please refer to Figure 6-Figure 8 As shown, the first end 21a of the lever 21 is provided with a second recess 212, the second recess 212 includes a second plane 212a and a third plane 212b intersecting with each other, in the first state, the trigger mechanism 3 abuts against the second plane 212a, and in the second state, the trigger mechanism 3 abuts against the third plane 212b.

[0118] In this embodiment, the second recess 212 at the first end 21a of the lever 21 serves as a force receiving part for receiving the driving force of the trigger mechanism 3. When the first end 21a of the lever 21 moves, at least part of the trigger mechanism 3 also moves with the first end 21a of the lever 21, so as to ensure that the trigger mechanism 3 can always provide driving force for the first end 21a of the lever 21. In the first state, the trigger mechanism 3 is in directional contact with the second plane 212a, so that the trigger mechanism 3 can stably drive the lever puncture mechanism 2 to move towards the skin, so that the needle head 23 can stably penetrate into the skin. In the second state, the lever 21 rotates, the angle between the force direction (the first direction X) of the trigger mechanism 3 and the second plane 212a changes, the third plane 212b intersecting with the second plane 212a starts to contact with the trigger mechanism 3, and the third plane 212b bears the driving force of the trigger mechanism 3. This arrangement makes the force direction of the trigger mechanism 3 and the normal direction of each force receiving surface of the first end 21a as close to parallel as possible, reduces the risk of misalignment sliding of the trigger mechanism 3 relative to the lever 21, improves the reliability of the stable rotation of the lever 21 relative to the support assembly 22, and enables the needle head 23 to stably pull out of the skin.

[0119] Please refer to Figure 6 and Figure 8As shown, in the first state, along the moving direction of the lever puncture mechanism 2 (the first direction X), one end of the second plane 212a close to the second end 21b is lower than the other end of the second plane 212a close to the third plane 212b, and the included angle a between the second plane 212a and the moving direction of the lever puncture mechanism 2 (the first direction X) is 80°≤a≤90°, and the included angle between the second plane 212a and the third plane 212b is obtuse.

[0120] In this embodiment, the angle relationship between the force direction of the trigger mechanism 3 (the first direction X) and the normal direction of the second plane 212a is close to parallel, and in the first state, the driving force received by the lever puncture mechanism 2 is the main component of the force of the trigger mechanism 3, so that the lever puncture mechanism 2 can quickly drive the needle 23 to penetrate into the skin. In the second state, when the lever 21 just starts to rotate, the angle relationship between the force direction of the trigger mechanism 3 and the normal direction of the second plane 212a changes from close to parallel to completely parallel, so that the driving force received by the first end 21a of the lever 21 as the main component of the force of the trigger mechanism 3 changes from small to large, so that the speed of the needle 23 of the second end 21b of the lever 21 gradually increases when the trigger mechanism 3 acts on the third plane 212b. Because the included angle between the third plane 212b and the second plane 212a is obtuse, the force direction of the trigger mechanism 3 can also be close to parallel to the normal direction of the third plane 212b, so that the trigger mechanism cannot be dislocated and slid relative to the first end 21a of the lever 21, and can continue to stably drive the lever 21 to rotate.

[0121] Please refer to Figure 6 , Figure 7 , Figure 8 , Figure 10 As shown, the first moving pair includes at least two hanging protrusions 222 and at least two first sliding grooves 14. The at least two hanging protrusions 222 are oppositely and elastically arranged on the bracket assembly 22, and the hanging protrusions 222 are used for hanging the biosensor base (not shown in the figure). The at least two first sliding grooves 14 are oppositely arranged on the shell 1, and one end of the first sliding groove 14 close to the needle 23 is closer to the inner wall of the shell 1. At least part of the hanging protrusions 222 is located in the first sliding groove 14, and the first sliding groove 14 can support the hanging protrusions 222. The shell 1 is further provided with a third recess 15, and the third recess 15 is located between the first sliding groove 14 and the second limiting portion 12. In the first state, the hanging protrusions 222 move to the third recess 15 under the guidance of the first sliding groove 14, and in the second state, the hanging protrusions 222 are located in the third recess 15, and there is a gap between the hanging protrusions 222 and the third recess 15 for the biosensor base to pass through.

[0122] In this embodiment, the housing 1 forms a support slope through the relatively arranged and inclined first slide groove 14, which is used to support the hook protrusion 222 disposed relative to the bracket assembly 22. This allows the lever puncture mechanism 2 to move relative to the housing 1 without sufficient external driving force. This prevents the lever puncture mechanism 2 from accidentally moving the needle 23 due to a small force during abnormal use, thereby causing the biosensor implant device to fail. When the user activates the trigger mechanism 3, the lever 21 drives the bracket assembly 22, and the bracket assembly 22 slides along the first slide groove 14 of the housing 1 toward the user's skin via the hook protrusion 222. Because the hook protrusion 222 is elastically disposed on the bracket assembly 22, it can elastically deform relative to the bracket assembly 22, allowing the bracket assembly 22 to continue to move along the inclined first slide groove 14 toward the user's skin. When the bracket assembly 22 is restricted in movement by the second limiting portion 12, it enters the second state. The elastically compressed hooking protrusion 222 returns to its natural state within the space of the third recessed portion 15, restricting the bracket assembly 22 from moving in the opposite direction relative to the housing (opposite to the first direction X), thereby allowing the lever 21 to stably rotate relative to the bracket assembly 22. At the same time, a gap exists between the hooking protrusion 222 and the third recessed portion 15. Since the hooking protrusion 222 in this embodiment is also used to hook the biosensor base, after the second state ends and the user removes the biosensor implant from the skin, the biosensor base can pass through the gap between the hooking protrusion 222 and the third recessed portion 15, remaining on the user's skin surface.

[0123] Therefore, in this embodiment, the hanging protrusion 222 and the first slide groove 14 can not only play a guiding role, so that the needle 23 can be directed into the skin, but also play a limiting role to prevent the biosensor implant device from failing. The hanging protrusion 222 can also be engaged with the third recessed portion 15 to stabilize the bracket assembly 22 relative to the shell 1 in the second state. Moreover, the hanging protrusion 222 can also be used to hang the biosensor base. The structure is simple and can realize multiple functions.

[0124] The biosensor base is connected to the biosensor. After the user uses the biosensor implant, the biosensor remains inside the user's skin, while the biosensor base remains outside. The biosensor base is provided with adhesive for adhering to the user's skin. The user installs a monitoring device, such as a transmitter, on the biosensor base, electrically connects it to the biosensor, and transmits or transfers information about the physiological status indicator to other devices. The biosensor implant device of this application does not impose any restrictions on the specific structure of the biosensor base.

[0126] In the first state and the second state, the hanging protrusion 222 can be disengaged from the first sliding groove 14 to release the sliding connection, and the sliding block 223 is always in sliding connection with the fourth sliding groove 16, so as to improve the reliability of the directional movement of the support assembly 22 relative to the shell 1, to enable the needle 23 to be stably inserted into and pulled out of the skin, and to reduce the risk of mispositioning of the needle 23 relative to the skin of the user.

[0127] In the above embodiment, the support assembly 22 is divided into an upper support 22a and a lower support 22b, the upper support 22a is in positioning cooperation with the positioning column 226 of the lower support 22b through the positioning hole 227, and the upper support 22a is fixedly connected with the second buckle 225 of the lower support 22b through the first buckle 224. The upper support 22a serves as a connecting piece of the lever 21, is provided with a pivot hole 229 to cooperate with the pivot 213 of the lever 21, the lower support 22b serves as a connecting piece of the hanging protrusion 222, is integrally connected with the hanging protrusion 222 through the elastically deformable component, and is used for accommodating the biosensor base. The separate arrangement enables the support assembly 22 to be manufactured in two parts and then assembled, so as to simplify the manufacturing process of the support assembly 22.

[0128] The upper support 22a is further provided with a large square hole 228a, and the lower support 22b is further provided with a small square hole 228b, which are respectively used for cooperating with the large square table 242 and the small square table 243 of the needle seat 24, so as to enable the support assembly 22 to limit the degrees of freedom of the needle seat 24 and prevent the needle seat 24 from mispositioning the needle 23 relative to the skin of the user. The needle seat 24 is provided with a needle hole 244 for mounting the needle 23.

When the end of the first stop block 311 away from the lever 21 cooperates with the end of the third stop block 171 close to the lever 21, the second stop block 312 is supported by the portion of the third limiting portion 17 between the third stop block 171 and the fourth stop block 172, and the first stop block 311 and the second stop block 312 connected thereto are clamped by the third limiting portion 17, so that the pressing piece 31 is fixed relative to the shell 1, and the user can not continue to press the pressing piece 31, and at the same time, the fourth stop block 172 has also separated from the pushing piece 32. The pushing piece 32 moves towards the lever 21 under the elastic force of the spring 33 in a compressed state, for driving the needle 23 to move towards the skin of the user, and in the second state, the lever 21 rotates to drive the needle 23 to separate from the skin of the user. The biological sensor implanting device of the present application can accumulate the force of the spring 33 in a compressed state by pressing once, and drive the needle 23 to quickly penetrate into and separate from the skin of the user through the transmission of the pushing piece 32 and the lever 21, thereby shortening the implanting time, and the operation is simple, which reduces the difficulty of use for the user.

[0131] Wherein, please refer to Figure 10 As shown, the shell 1 is provided with a pressing piece hole 10 for the pressing piece 31 to pass through, and at least part of the pressing piece 31 is located outside the shell 1.

[0136] Please refer to Figure 11 and Figure 13 As shown in the figure, the trigger mechanism 3 further includes a safety piece 34, the safety piece 34 is located outside the housing 1, at least part of the safety piece 34 is connected to the pressing piece 31, and at least part of the safety piece 34 abuts against the housing 1.

[0137] In this embodiment, the safety member 34 is used to prevent external forces from mistakenly driving the pressing member 31 to slide relative to the housing 1, thereby avoiding failure of the biosensor implant device due to misoperation of the trigger mechanism 3 and the lever puncture mechanism 2 in abnormal use.

[0138] The safety piece 34 can be integrally formed with the pressing piece 31 , and the user only needs to break off the safety piece 34 during use.

[0139] Please refer to Figures 1-4 、 Figure 6 and Figure 14 As shown, the biosensor implant device further includes a protective cover 4, which is engaged with the opening 18 of the housing 1. The protective cover 4 includes a first boss 41 and a second boss 42. The first boss 41 can support the bracket assembly 22, and the second boss 42 is used to support the biosensor base.

[0140] In this embodiment, protective cover 4 is used to prevent foreign matter from entering the interior of housing 1, reducing the possibility of failure of trigger mechanism 3, lever puncture mechanism 2, and biosensor. When protective cover 4 is attached to housing 1, first boss 41 supports bracket assembly 22, and second boss 42 supports the biosensor base. This prevents bracket assembly 22 and biosensor base from moving toward opening 18 of housing 1 when the biosensor implant device of this application is not in use, reducing the possibility of failure of the biosensor implant device and thereby improving the reliability of the biosensor implant device.

[0141] Among them, the protective cover 4 is provided with a rib 44, the rib 44 is provided with a third buckle 43, the opening 18 of the shell 1 is provided with a skirt 19, the rib 44 is used to surround the skirt 19, and is clamped with the skirt 19 through the third buckle 43. The protective cover 4 is also provided with a hand position 45 to facilitate the user to remove the protective cover 4 from the shell 1.

[0142] The working process of the biosensor implant device of this application is as follows:

[0143] The user removes the protective cover 4 from the housing 1 so that the opening 18 of the housing 1 can be brought into contact with the user's skin. At the same time, the user breaks the safety member 34 from the pressing member 31 so that the user can press the pressing member 31. The pressed pressing member 31 forces the third limiting portion 17 to deform in a direction away from the pushing member 32, and the pressing member 31 can move toward the direction close to the lever 21. When the first stopper 311 moves to the end of the third stopper 171 close to the lever 21, the third limiting portion 17 rebounds in a direction close to the pushing member 32. , so that the end of the third stopper 171 closer to the lever 21 cooperates with the end of the first stopper 311 farther from the lever 21, and the portion between the third stopper 171 and the fourth stopper 172 can support the second stopper 312. As a result, the pressing member 31 is caught by the third limiting portion 17, and the fourth stopper 172 disengages from the fifth stopper 322 of the pushing member 32. Under the force of the compressed spring 33, the spring 33, with the stationary pressing member 31 as a force support, drives the pushing member 32 toward the lever puncture mechanism 2. Driven by the pushing member 32, the lever puncture mechanism 2 enters the first state, driving the needle 23 relative to the housing 1 along the first direction X to penetrate the user's skin, thereby implanting the biosensor into the user's body. When the first end 21a of the lever 21 is free from the restraining effect of the first limiting portion 11 (first plane) and enters the rotation space 13 (first recess), and the bracket assembly 22 is supported by the second limiting portion 12 (limiting protrusion), the needle 23 penetrates the deepest part of the user's skin, entering the second state. The lever 21 rotates relative to the bracket assembly 22, and the second end 21b of the lever 21 drives the needle 23 out of the user's skin. In the first state, the hooking protrusion 222 of the bracket assembly 22 hooks onto the biosensor base and drives the biosensor base toward the user's skin. In the second state, the hooking protrusion 222 enters the third recess 15, and a gap is formed between the hooking protrusion 222 and the third recess 15. When the needle 23 is separated from the skin, the user holds the shell 1 and removes the biosensor implant device from the skin. Since the biosensor has remained in the user's body, the biosensor base connected to the biosensor will pass through the gap between the hanging protrusion 222 and the third recessed portion 15 and separate from the biosensor implant device. The biosensor base is adhered to the surface of the user's skin by adhesive. The user can install electronic devices such as transmitters on the biosensor base to electrically connect them to the biosensor, and transmit or transfer information on the physiological status indicators to be monitored to other devices.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
