Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a sensor implantation mechanism. Background Art

[0002] With the gradual improvement of the living standards of residents, people are becoming more and more concerned about their own health conditions. Based on this, human sensor devices are increasingly applied to people's daily lives. When a human sensor device is in use, it implants the sensor device into the surface skin of a user, and uses the sensor device to detect the blood in the user's body, so as to calculate the index values related to the user's health.

[0003] Currently, when a human sensor device is implanted into the human body, it usually needs to be assisted by an implantation device. However, existing auxiliary implantation devices are generally for single use, that is, after an auxiliary implantation device is used once, it cannot be used again and can only be discarded, which increases the overall cost of the product and is also prone to polluting the environment. Summary of the Invention

[0004] This application provides a sensor implantation mechanism, which can realize the reuse of the implantation device, thereby reducing the product cost and protecting the environment.

[0005] This application provides a sensor implantation mechanism, including a sensor module and a reusable auxiliary implantation device;

[0006] The sensor module includes a packaging box, a module bracket, a guiding needle and a sensor device. The packaging box includes a bottom shell and a box cover, and the box cover is detachably covered on the top of the bottom shell;

[0007] The module bracket, the guiding needle and the sensor device are all arranged in the bottom shell. The module bracket is detachably connected to the bottom shell, the sensor device is detachably connected to the module bracket, and the guiding needle is detachably installed on the sensor device;

[0008] The reusable auxiliary implantation device includes an injection structure and a reset structure. The injection structure is provided with a first engaging structure, and the module bracket is provided with a second engaging structure. The first engaging structure is used to engage with the second engaging structure to fix the module bracket to the injection device, and the first engaging structure is used to drive the module bracket to disengage from the bottom shell;

[0009] The injection structure can move along the injection direction to drive the sensor device to be implanted into the human body, and the injection structure can also move in the opposite direction of the injection direction to drive the module bracket to disengage from the sensor device and make the sensor device stay in the human body;

[0010] The injection structure is provided with a clamping assembly for clamping the guiding needle. When the injection structure moves in the direction opposite to the injection direction, the injection structure is further configured to drive the guiding needle away from the sensor device;

[0011] The reset structure is configured to drive the second engaging structure away from the first engaging structure, so that the module bracket is separated from the injection structure. The reset structure is further configured to drive the guiding needle away from the clamping assembly.

[0012] In the sensor implantation mechanism of the present application, the reusable auxiliary implantation device and the sensor module are designed as two independent structures. When it is necessary to implant the sensor device into the user's body, the lid of the packaging box can be opened, and the module bracket in the packaging box is fixed to the injection structure through the first engaging structure and the second engaging structure, and the guiding needle is clamped by the clamping assembly. During this process, the packaging box is separated from the module bracket, so that the module bracket, the sensor device and the guiding needle are transferred to the injection structure. Subsequently, the sensor device is implanted into the human body by using the injection structure, then the module bracket is separated from the sensor device, and the guiding needle is withdrawn from the sensor device. Finally, the reset structure is used to drive the second engaging structure to disengage from the first engaging structure, so that the module bracket is separated from the injection structure, and the guiding needle is driven away from the clamping assembly, so that the injection structure returns to the unused state. When it is necessary to implant the sensor device into the human body next time, a new sensor module can be taken, and the module bracket is connected to the injection structure to complete the implantation of the sensor device. It can be seen that the auxiliary implantation device of the sensor implantation mechanism in the present application can be reused, which not only reduces the product cost, but also is beneficial to environmental protection.

[0025] In some alternative embodiments, the clamping assembly includes two clamping rods which are symmetrically arranged with respect to the axis of the back needle bracket, and the first ends of the clamping rods are connected to the inner wall of the back needle bracket.

[0026] The clamping rods are inclined with respect to the axis of the back needle bracket so that the second ends of the two clamping rods approach each other, and the second ends of the two clamping rods cooperate to clamp the guiding needle.

[0027] In some alternative embodiments, the reset structure includes a return pin ejector rod disposed within the lower cover. When the first engaging structure is engaged with the second engaging structure, the lower cover can be assembled with the housing from the bottom of the housing, and the return pin ejector rod is used to drive the second ends of the two clamping rods away from each other, so that the guiding needle disengages from the clamping assembly.

[0028] In some alternative embodiments, the reset structure includes a key ejector rod connected to the key body, and the key ejector rod extends along the axis direction of the inner sleeve.

[0029] When the key body moves along the axis direction of the inner sleeve, the key ejector rod can extend between the two clamping rods and drive the second ends of the two clamping rods away from each other, so that the guiding needle disengages from the clamping assembly.

[0030] In some alternative embodiments, there are a first gear position and a second gear position between the key module and the housing.

[0031] When the key module and the housing are in the first gear position, the key module is used to drive the first limiting structure to switch from the limiting state to the unlocking state.

[0033] In some alternative embodiments, the key module further includes key limiting ribs, and key limiting platforms are provided on the inner wall of the housing.

[0034] The housing can rotate relative to the key module around the axis of the main bracket.

[0039] In some alternative embodiments, the second limiting structure includes a return needle buckle disposed on the outer wall of the return needle bracket and a second sleeve buckle disposed on the inner sleeve. When the second limiting structure is in the limiting state, the return needle buckle abuts against the bottom of the second sleeve buckle;

Detailed implementation manners

[0081] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0082] The reusable auxiliary implantation device in the embodiments of the present application can be used to assist in implanting the sensor device into the skin of a user. After the sensor device is implanted into the user's skin, the reusable auxiliary implantation device can also return to its initial state to facilitate continued use next time, thereby realizing the reusable function of the reusable auxiliary implantation device.

[0083] Based on this, the solution in the embodiments of the present application can include two independent structures: a reusable auxiliary implantation device and a sensor module. When it is necessary to implant the sensor device into the user's skin, the sensor device in the sensor module can be assembled with the reusable auxiliary device. After the implantation is completed, the structure remaining on the reusable auxiliary implantation device is removed to enable the reusable auxiliary implantation device to return to its initial state for the next use.

[0084] Thus, referring to Figure 1 and Figure 2 , the sensor module 100 in the embodiments of the present application can include a packaging box 110 and a module bracket 120, a sensor device 130, a guiding needle 140, and a desiccant 150 disposed in the packaging box 110. The packaging box 110 can include a bottom shell 111 and a box cover 112. The bottom shell 111 and the box cover 112 are detachably connected so that the box cover 112 can be closed on the bottom shell 111, or the box cover 112 can be removed from the bottom shell 111.

[0085] Referring to Figure 3 , the module bracket 120 and the bottom shell 111 are detachably connected. Specifically, the module bracket 120 can be installed along the circumferential direction of the bottom shell 111 on the inner wall of the bottom shell 111. The inner wall of the bottom shell 111 can be provided with a clamping structure 1111, and the module bracket 120 can be relatively fixed to the inner wall of the bottom shell 111 through the clamping structure 1111. When an external force acts on the clamping structure 1111, the module bracket 120 can also be separated from the clamping structure 1111, so that it is convenient to take out the module bracket 120 from the bottom shell 111.

[0086] Referring to Figure 4, the middle part of the module bracket 120 has an annular hole, which can be used to accommodate the sensor device 130. When the sensor device 130 is installed on the module bracket 120, the inner wall of the annular hole contacts the side wall of the sensor device 130, thereby playing a role in initially limiting the sensor device 130.

[0087] The inner wall of the annular hole can also be respectively provided with a positive buckle 121 and a negative buckle 122. Correspondingly, the sensor device 130 can be respectively provided with a positive slot 1301 and a negative slot 1302. When the sensor device 130 is placed in the annular hole, the positive buckle 121 can be snapped into the positive slot 1301, and the negative buckle 122 can be snapped into the negative slot 1302. At this time, under the combined action of the positive buckle 121 and the negative buckle 122, the sensor device 130 can be relatively fixed to the module bracket 120.

[0088] Specifically, the positive slot 1301 of the sensor device 130 is arranged on the side of the sensor device 130, and a part of the positive slot 1301 extends to the bottom of the sensor device 130. When the positive buckle 121 is snapped into the slot, a part of the positive buckle 121 abuts against the bottom surface of the sensor device 130.

[0089] The negative slot 1302 of the sensor device 130 is arranged on the side of the sensor device 130, and the opening of the negative slot 1302 is opened on the side facing the top of the sensor device 130. When the negative buckle 122 is snapped into the negative slot 1302, the negative buckle 122 can abut against the bottom of the negative slot 1302.

[0090] Refer to Figure 4 and Figure 5 , when a force is applied to the sensor device 130 along the axis direction of the annular hole, if the force acts on the top of the sensor device 130 (the arrow direction in Figure 5 can be referred to), it means pressing the sensor device 130 from top to bottom. At this time, the force acting on the sensor device 130 can be understood as the driving force for implanting the sensor device 130 into the user's skin, and this driving force is used to drive the sensor device 130 to move along the implantation direction. The positive buckle 121 can be an elastic structure. When the sensor device 130 is subjected to a downward force, this force can drive the sensor device 130 to move downward, causing the positive buckle 121 to disengage from the positive slot 1301. During this process, the bottom of the negative slot 1302 is gradually away from the negative buckle 122, so the negative slot 1302 and the negative buckle 122 will not affect the sensor device 130 from being disengaged from the module bracket 120.

[0091] On the contrary, when the sensor device 130 is pushed upward from the bottom, the force acting on the sensor device 130 at this time can be understood as driving the sensor device 130 to move in the opposite direction of the implantation direction. Since the negative buckle 122 is abutted against the bottom of the negative clamping groove 1302, when the force is applied to the sensor device 130, under the buckling action of the negative clamping groove 1302 and the negative buckle 122, the sensor device 130 cannot move relative to the module support 120, that is, the negative clamping groove 1302 and the negative buckle 122 can be used to limit the sensor device 130 from escaping from the module support 120 in the opposite direction of its implantation direction.

[0092] refer to Figure 6 The sensor device 130 may be provided with a through hole 1303 for passing the guide needle 140. The guide needle 140 includes a plastic handle 141 and a needle body 142. The needle body 142 can be located in the needle groove of the puncture needle after passing through the through hole 1303. When the sensor device 130 is implanted in the user's skin, the guide needle 140 can penetrate the skin before the puncture needle, thereby guiding the puncture of the puncture needle.

[0093] refer to Figure 7 A first sealing rubber ring 1304 may be provided on the inner wall of the through hole 1303. When the guide needle 140 is installed on the sensor device 130 through the through hole 1303, part of the plastic handle 141 is located in the through hole 1303, and the plastic handle 141 and the first sealing rubber ring 1304 abut against each other, thereby ensuring the sealing between the guide needle 140 and the sensor device 130.

[0094] In addition, refer to Figure 8 The bottom of the bottom shell 111 may also be provided with a sealing column 160, which extends along the axial direction of the bottom shell 111, and an opening is provided at one end of the sealing column 160 away from the bottom of the bottom shell 111. When the module bracket 120 with the sensor device 130 installed is installed on the bottom shell 111, the puncture needle of the sensor device 130 and the needle body 142 of the guide needle 140 can both extend into the sealing column 160 through the opening, thereby improving the sealing performance between the bottom shell 111 and the sensor device 130.

[0095] like Figure 8 As shown, a second sealing rubber ring 1312 may be provided between the bottom of the sensor device 130 and the top of the sealing column 160, thereby further improving the sealing performance between the bottom shell 111 and the sensor device 130. The desiccant 150 may be provided in the bottom shell 111 around the sealing column 160 to keep the inside of the bottom shell 111 dry.

[0096] refer to Figure 9The sensor device 130 may include a sensor bottom shell 131, a sensor upper shell 132, a sensor 133, a sensor bracket 134, a circuit board 135 and an application tape 136, wherein the sensor 133, the sensor bracket 134 and the circuit board 135 are all arranged on the sensor bottom shell 131.

[0097] For details, please refer to Figure 9 and Figure 10 The sensor 133 may be fixedly connected to the sensor bottom shell 131, and a puncture needle of the sensor 133 used to pierce the user's skin is inserted into the sensor bottom shell 131, so that the puncture needle is located outside the sensor bottom shell 131. The sensor bracket 134 is located on the side of the sensor 133 away from the sensor bottom shell 131, so that the sensor bracket 134 can press the sensor 133 against the sensor bottom shell 131. The sensor bottom shell 131 may be provided with a glue groove 1311, and a part of the sensor bracket 134 may be located in the glue groove 1311, and the sensor bracket 134 is bonded to the glue groove 1311 by glue, thereby achieving the fixation between the sensor bracket 134 and the sensor bottom shell 131.

[0098] The circuit board 135 is provided with an avoidance hole. When the circuit board 135 is fixed in the sensor bottom shell 131 , the sensor bracket 134 is located in the avoidance hole so that the bottom of the circuit board 135 can be fixedly connected with the sensor bottom shell 131 .

[0099] The sensor upper shell 132 is located on the side of the circuit board 135 away from the sensor bottom shell 131. The connector on the circuit board 135 can contact the contact of the sensor 133 to achieve the connection of the signal transmission channel. The sensor upper shell 132 can cover the sensor bottom shell 131, thereby ensuring that the interior of the sensor bottom shell 131 forms a relatively closed space to prevent foreign substances from contaminating the sensor 133.

[0100] The application tape 136 can be fixed to the side of the sensor bottom shell 131 facing away from the sensor upper shell 132. When the sensor device 130 is implanted in the user's skin, the application tape 136 can be used to adhere the sensor device 130 to the surface of the user's skin, thereby strengthening the stability of the connection between the sensor 133 and the user's skin.

[0101] As described above, the sensor device 130 has a through-hole 1303 passing through the guiding needle 140. Based on this, the dressing tape 136, the sensor bracket 134, the sensor bottom case 131, and the sensor top case 132 can all be provided with the through-hole 1303, so that the guiding needle 140 can pass through the through-hole 1303 of the sensor top case 132 to the through-hole 1303 of the dressing tape 136. At this time, the first sealing rubber ring 1304 can be arranged on the inner wall of the through-hole 1303 of the sensor bracket 134, and a protrusion can also be arranged on the inner wall of the through-hole 1303 of the sensor bottom case 131. Correspondingly, a limiting groove can also be arranged on the plastic handle 141 of the guiding needle 140, and the protrusion is engaged in the limiting groove 126 to prevent the guiding needle 140 from rotating relative to the sensor device 130.

[0102] In addition, when the plastic handle 141 of the guiding needle 140 is located in the through-hole 1303, the surface of the plastic handle 141 facing the puncture needle 142 can also be flush with the surface of the sensor bottom case 131 facing away from the sensor bracket 134. That is to say, the plastic handle 141 does not protrude from the surface of the sensor bottom case 131. When the guiding needle 140 is used to assist the sensor device 130 to penetrate into the user's skin and then the guiding needle 140 is withdrawn from the sensor device 130, the guiding needle 140 can be directly withdrawn from the sensor device 130 at one time. If the plastic handle 141 protrudes from the surface of the sensor bottom case 131, when withdrawing the needle, it is necessary to first completely retract the plastic handle 141 into the through-hole 1303 and then withdraw the guiding needle 140 from the sensor device 130. It can be seen that the design in this embodiment can make it more convenient and simple to take out the guiding needle 140 from the sensor device 130.

[0103] The reusable implant device in the embodiment of the present application may include an injection structure and a reset structure. Among them, the module bracket 120 installed with the sensor device 130 can be connected to the injection structure, and the injection structure can move along the injection direction to facilitate implanting the sensor device 130 into the human body. Subsequently, when the injection structure moves in the opposite direction of the injection direction, the injection structure can also drive the module bracket 120 and the guiding needle 140 to disengage from the sensor device 130, so that the sensor device 130 can stay in the human body. Finally, the reset structure can drive the module bracket to separate from the injection structure and drive the guiding needle to disengage from the injection structure, so that the reusable implant device can return to its initial state.

[0104] Based on this, refer to Figure 11, the above injection structure may include a needle retraction bracket 210 and an inner sleeve 220. Additionally, the reusable auxiliary implantation device 200 in the embodiments of the present application may further include a main bracket 230, a housing 240, a lower cover 250, and a button module 260. Among them, the inner sleeve 220 is sleeved and connected to the needle retraction bracket 210, the main bracket 230 is sleeved and connected to the inner sleeve 220, the housing 240 is sleeved and connected to the main bracket 230, the lower cover 250 can be closed on the housing 240, and the button module 260 is arranged at the top of the housing 240.

[0105] Reference Figure 12 , the connection between the lower cover 250 and the housing 240 is detachable. When the lower cover 250 is closed on the housing 240, the reusable auxiliary implantation device 200 is in an unused state. When it is necessary to use the reusable auxiliary implantation device 200, the lower cover 250 can be removed from the housing 240, so that the inner sleeve 220 is exposed at the bottom of the housing 240, facilitating the connection between the inner sleeve 220 and the sensor module 100.

[0106] Exemplarily, as Figure 12 shown, a limiting buckle 243 may be provided on the inner wall of the housing 240, and an annular slot 251 may be provided on the inner wall of the lower cover 250. The annular slot 251 is arranged circumferentially around the lower cover 250. When the lower cover 250 is closed on the housing 240, the limiting buckle 243 is snapped into the annular slot 251. It can be understood that by providing the annular slot 251, no matter from which angle the lower cover 250 is closed on the housing 240, the snap-fit of the limiting buckle 243 and the annular slot 251 can be quickly achieved without the need for alignment work. When it is necessary to remove the lower cover 250, just pull down the lower cover 250 so that the limiting buckle 243 is disengaged from the limiting slot.

[0107] In the inner sleeve 220 of this embodiment, a first engaging structure is provided, and a second engaging structure is provided on the module bracket 120. When the sensor module 100 is installed with the inner sleeve 220, the first engaging structure and the second engaging structure can be snapped together, so that the module bracket 120 and the inner sleeve are relatively fixed. When the first engaging structure is disengaged from the second engaging structure, the inner sleeve 220 can be disengaged from the module bracket 120.

[0108] Reference Figure 14, the first engaging structure may include a top rib 221 disposed on the inner wall of the inner sleeve 220, and the second engaging structure may include a first bracket buckle 124 disposed on the module bracket 120. Among them, the top rib 221 is disposed near the bottom of the inner sleeve 220. When the first engaging structure and the second engaging structure are engaged, the first bracket buckle 124 abuts against the top rib 221. There are at least two top ribs 221 disposed on the inner sleeve 220. Correspondingly, there are also at least two first bracket buckles 124. When each top rib 221 abuts against the corresponding first bracket buckle 124 respectively, the inner sleeve 220 and the module bracket 120 can be kept relatively fixed.

[0109] Based on this, looking back Figure 1 , the module bracket 120 is further provided with a second bracket buckle 125. When the module bracket 120 is placed in the bottom case 111, the second bracket buckle 125 can abut against the engaging structure 1111, so as to realize the relative fixation between the module bracket 120 and the bottom case 111.

[0110] Further, referring again to Figure 14 , the module bracket 120 is further provided with an elastic wall 123. The first bracket buckle 124 and the second bracket buckle 125 are both connected to the elastic wall 123, and the second bracket buckle 125 is located below the first bracket buckle 124.

[0111] The elastic wall 123 can be disposed obliquely to the axis direction of the module bracket 120. Along the radial direction of the inner sleeve 220, the distance between the second bracket buckle 125 and the axis of the inner sleeve 220 is greater than the distance between the first bracket buckle 124 and the axis of the inner sleeve 220.

[0112] Before assembling the module bracket 120 and the inner sleeve 220, the module bracket 120 and the bottom case 111 are abutted through the second bracket buckle 125 and the engaging structure 1111. When the bottom case 111 is assembled with the inner sleeve 220 from bottom to top, the top rib 221 can squeeze the elastic wall 123 inward, so that the second bracket buckle 125 disengages from the engaging structure 1111. During this process, the top rib 221 can abut against the lower part of the first bracket buckle 124, so as to complete the fixation between the inner sleeve 220 and the module bracket 120, and the bottom case 111 can be separated from the module bracket 120.

[0113] Referring together to Figure 13 and Figure 14, the backstitch bracket 210 is provided with a clamping assembly 211. The clamping assembly 211 has a clamping state and a non-clamping state. When the clamping assembly 211 is in the clamping state, the clamping assembly 211 can be used to clamp the guiding needle 140. When the clamping assembly 211 is in the non-clamping state, the guiding needle 140 can be released from the clamping assembly 211. Specifically, when the module bracket 120 equipped with the sensor device 130 is relatively fixed to the inner sleeve 220, the clamping assembly 211 can clamp the plastic handle 141 of the guiding needle 140, and when the sensor device 130 is not implanted into the user's skin, the clamping assembly 211 and the guiding needle 140 remain relatively fixed.

[0114] Reference Figure 14 and Figure 15 , a first limiting structure 202 is provided between the inner sleeve 220 and the main bracket 230. When the first limiting structure 202 is in the limiting state, the inner sleeve 220 and the main bracket 230 are relatively fixed. When the first limiting structure 202 is in the unlocking state, the inner sleeve 220 can move relative to the main bracket 230 along the axial direction of the inner sleeve 220.

[0115] The first limiting structure 202 may include a first sleeve buckle 2022 provided on the inner wall of the inner sleeve 220 and a lapping portion 2021 provided inside the main bracket 230. Among them, the first sleeve buckle 2022 protrudes from the inner wall surface of the inner sleeve 220, and the lapping portion 2021 is located in the middle of the main bracket 230. There is a certain gap between the lapping portion 2021 and the wall surface of the main bracket 230, and this gap can be used for the side wall of the inner sleeve 220 to pass through. That is to say, the inner sleeve 220 is sleeved on the lapping portion 2021, and the main bracket 230 is sleeved on the inner sleeve 220.

[0116] When the first limiting structure 202 is in the limiting state, that is, the first sleeve buckle 2022 abuts against the top surface of the lapping portion 2021. When the first limiting structure 202 is in the unlocking state, that is, the first sleeve buckle 2022 disengages from the lapping portion 2021. In addition, a main spring 270 is also connected between the inner sleeve 220 and the main bracket 230. When the first limiting structure 202 is in the limiting state, the main spring 270 is in a compressed state.

[0117] When the first limiting structure 202 switches to the unlocking state, the first sleeve buckle 2022 disengages from the lapping portion 2021. Due to the elastic potential energy of the main spring 270, the main spring 270 can drive the inner sleeve 220 to move downward relative to the main bracket 230.

[0118] It should be noted that when assembling the sensor module 100 with the reusable auxiliary implantation device 200, the lid 112 of the sensor module 100 can be removed first, and then the bottom shell 111 can be assembled with the reusable auxiliary implantation device 200, so as to ensure that the sensor device 130 is always in a sealed state before being implanted into the user's skin.

[0119] On this basis, referring to Figure 16 and Figure 17 , a sleeve limiting rib 222 can also be provided at the bottom of the inner sleeve 220. Correspondingly, the module bracket 120 can be provided with a limiting groove 126. When assembling the bottom shell 111 with the inner sleeve 220 from the bottom of the outer shell 240, the limiting rib can be inserted into the limiting groove 126, so as to ensure the alignment between the top rib 221 and the first bracket buckle 124.

[0120] To facilitate the accurate insertion of the sleeve limiting rib 222 into the limiting groove 126, alignment lines can also be provided on the surface of the outer shell 240, and alignment lines can also be provided on the surface of the bottom shell 111. When the two alignment lines are aligned, it means that the sleeve limiting rib 222 is exactly opposite to the limiting groove 126.

[0121] After the module bracket 120 is fixed to the inner sleeve 220, the bottom shell 111 can be pulled down to separate the module bracket 120 from the bottom shell 111, so as to facilitate the subsequent implantation of the sensor device 130.

[0122] Referring to Figure 18 , the button module 260 can include a button body 261 and a button spring 262. A button hole 242 can be provided at the top of the outer shell 240. The button body 261 can pass through the button hole 242, and the button spring 262 can be connected between the button body 261 and the main bracket 230. Under the action of an external force, the button body 261 can move relative to the outer shell 240 along the axis direction of the inner sleeve 220. During this process, the button body 261 can compress the button spring 262. When the external force disappears, the button spring 262 can drive the button body 261 to return to the initial position.

[0123] Combining Figure 14 and Figure 18 , when the first limiting structure 202 is in the limiting state, the first sleeve buckle 2022 abuts against the top surface of the overlapping portion 2021. At this time, when the button body 261 is pressed down, the bottom of the button body 261 can contact the top of the first inner cylinder buckle. During the continuous pressing of the button body 261, the button body 261 can squeeze the first sleeve buckle 2022, so that the first sleeve buckle 2022 disengages from the top surface of the overlapping portion 2021, thus completing the switching of the first limiting structure 202 from the limiting state to the unlocking state.

[0124] The bottom of the key body 261 may be provided with a first guiding surface, which is an inclined surface. The top of the first sleeve buckle 2022 may be provided with a second guiding surface, which is also an inclined surface. Moreover, the first guiding surface and the second guiding surface are arranged in parallel. When the key body 261 contacts the first sleeve buckle 2022, the first guiding surface contacts the second guiding surface. During the process of the key body 261 moving downward continuously, the first guiding surface can generate a force that extrudes the first sleeve buckle 2022 outward, causing the first sleeve buckle 2022 originally facing the overlapping part 2021 to be extruded into a state misaligned with the overlapping part 2021, so that the first sleeve buckle 2022 can move to the gap between the overlapping part 2021 and the inner wall of the main bracket 230.

[0125] It should be noted that in the initial state of the reusable auxiliary implantation device 200 in this embodiment, the first limiting structure 202 is in the unlocked state, the inner sleeve 220 and the main bracket 230 are in a state of relative movement, and the first sleeve buckle 2022 of the inner sleeve 220 is located below the overlapping part 2021.

[0126] Reference Figure 19 , a second limiting structure 201 may be provided between the retraction needle bracket 210 and the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the retraction needle bracket 210 and the inner sleeve 220 are relatively fixed. When the second limiting structure 201 is in the unlocked state, the retraction needle bracket 210 can move relative to the inner sleeve 220 along the axial direction of the inner sleeve 220.

[0127] Specifically, the second limiting structure 201 may include a retraction needle buckle 2012 provided on the outer wall of the retraction needle bracket 210 and a second sleeve buckle 2011 provided on the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the retraction needle buckle 2012 abuts against the bottom of the second sleeve buckle 2011, so that the retraction needle bracket 210 and the inner sleeve 220 are relatively fixed.

[0128] A retraction needle spring 280 may also be connected between the retraction needle bracket 210 and the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the retraction needle spring 280 is in a compressed state. When the second limiting structure 201 switches to the unlocked state, due to the elastic potential energy of the retraction needle spring 280, it can drive the retraction needle bracket 210 to move upward relative to the inner sleeve 220.

[0129] Refer to together Figure 13 and Figure 19, a third limiting structure is further provided on the inner wall of the main bracket 230, and the third limiting structure can be arranged at a position close to the bottom of the main bracket 230. As described above, the inner sleeve 220 can move downward relative to the main bracket 230, and the third limiting structure can be used to limit the moving distance of the inner sleeve 220 relative to the main bracket 230, preventing the main spring 270 from undergoing plastic deformation due to an excessive moving distance of the inner sleeve 220.

[0130] The third limiting structure may include a bracket hook 232 arranged on the inner wall of the main bracket 230. The number of the bracket hooks 232 may be the same as the number of the second sleeve buckles 2011, and they are arranged in one-to-one correspondence. When the inner sleeve 220 moves relative to the main bracket 230, the second limiting structure 201 is in a limiting state, that is, the inner sleeve 220 and the return needle bracket 210 are relatively fixed, and the inner sleeve 220 drives the return needle bracket 210 to move downward together. Since the return needle buckle 2012 abuts against the bottom of the second sleeve buckle 2011, when the bracket hook 232 and the inner sleeve 220 play a limiting role, the return needle buckle 2012 is clamped between the bracket hook 232 and the second sleeve buckle 2011. At this time, if the inner sleeve 220 continues to move downward, the bracket hook 232 and the second sleeve buckle 2011 can cooperate to squeeze the return needle buckle 2012, so that the return needle buckle 2012 is separated from the contact with the second sleeve buckle 2011, and then the bracket hook 232 abuts against the bottom of the second sleeve, so as to make the main bracket 230 and the inner sleeve 220 relatively fixed.

[0131] It can be understood that the bracket buckle in this embodiment can not only be used to limit the moving distance of the inner sleeve 220, but also be used to drive the second limiting structure 201 to switch from the limiting state to the unlocking state. And during the process of the inner sleeve 220 continuously moving downward relative to the main bracket 230, it is the process of implanting the sensor device 130 into the user's skin. When the bracket hook 232 abuts against the second sleeve buckle 2011, it means that the sensor device 130 is implanted in place.

[0132] A third guiding surface may be further provided at the bottom of the return needle buckle 2012, and a fourth guiding surface may be further provided at the top of the bracket hook 232. Both the third guiding surface and the fourth guiding surface are inclined in the axial direction of the inner sleeve 220. And the third guiding surface is parallel to the fourth guiding surface. When the return needle buckle 2012 contacts the bracket hook 232, the third guiding surface fits with the fourth guiding surface. Under the squeezing action of the second sleeve buckle 2011, the third guiding surface can slide along the fourth guiding surface, so that the return needle buckle 2012 can more easily break away from the second sleeve buckle 2011.

[0133] Since the back needle holder 210 is provided with a clamping assembly 211 for clamping the guiding needle 140, after the sensor device 130 is implanted into the user's skin, due to the second limiting structure 201 being in an unlocked state, the elastic potential energy of the back needle spring 280 can drive the back needle holder 210 to move upward relative to the inner sleeve 220. During this process, the back needle holder 210 can drive the guiding needle 140 to move upward, so that the guiding needle 140 is separated from the sensor device 130.

[0134] Refer again to Figure 13 and Figure 14 , the clamping assembly 211 may include two clamping rods 2111, and the two clamping rods 2111 may be symmetrically arranged on the inner wall of the back needle holder 210 with the axis of the back needle holder 210 as the axis of symmetry. The clamping rod 2111 is rotatably connected to the inner wall of the back needle holder 210 relative to the back needle holder 210. Specifically, one end of the clamping rod 2111 is connected to the back needle holder 210, and the other end is a free end. When the clamping assembly 211 is in a clamped state, the free ends of the two clamping rods 2111 approach each other, so as to clamp the guiding needle 140.

[0135] The clamping rod 2111 may be, for example, an elastic rod, and the elastic rod is arranged obliquely to the axis of the back needle holder 210. When the two clamping rods 2111 are squeezed by an external force so that the free ends of the two clamping rods 2111 move away from each other, the distance between the free ends of the two clamping ends becomes larger, so that the guiding needle 140 cannot be clamped, and the guiding needle 140 can naturally fall off under the action of gravity. After the external force disappears, the clamping rod 2111 can return to the clamped state under the action of elasticity.

[0136] Alternatively, a reset member may be provided between the clamping rod 2111 and the inner wall of the back needle holder 210. In the initial state, under the action of the reset member, the free ends of the two clamping rods 2111 approach each other so that the clamping assembly 211 is in a clamped state. When the clamping rod 2111 is driven by an external force to rotate relative to the back needle holder 210 so that the free ends of the two clamping rods 2111 move away from each other, the guiding needle 140 can be detached. At this time, after the external force disappears, under the action of the reset member, the clamping rod 2111 can rotate relative to the back needle holder 210 again, so as to return to the clamped state.

[0137] It can be understood that when the module bracket 120 is fixedly opposed to the inner sleeve 220, since the plastic handle 141 of the guiding needle 140 protrudes from the module bracket 120 and extends towards the button module 260. During the process of fixing the module bracket 120 and the inner sleeve 220, the guiding needle 140 can squeeze the two clamping rods 2111 from bottom to top, so that the free ends of the two clamping rods 2111 move away from each other, facilitating the plastic handle 141 of the guiding needle 140 to pass through between the free ends of the two clamping rods 2111. After the module bracket 120 is fixed, under the reset action, the clamping rod 2111 can clamp the plastic handle 141 of the guiding needle 140 and remain relatively fixed with the plastic handle 141.

[0138] When the return needle bracket 210 moves upward relative to the inner sleeve 220 and drives the guiding needle 140 to disengage from the sensor device 130, the reusable auxiliary implantation device 200 can also be used to drive the clamping assembly 211 to switch from the clamped state to the unclamped state, so that the guiding needle 140 can fall off.

[0139] Based on this, in some embodiments, referring to Figure 20 , the reset structure may include a return needle ejector rod 290 disposed in the lower cover 250. The return needle ejector rod 290 extends along the axis direction of the lower cover 250 to protrude from the upper surface of the lower cover 250.

[0140] There may be two return needle ejector rods 290, and the two return needle ejector rods 290 are arranged in one-to-one correspondence with the two clamping rods 2111. After the implantation of the sensor device 130 is completed, when the lower cover 250 is assembled with the outer shell 240, the two return needle ejector rods 290 can respectively act on the bottoms of the two clamping rods 2111 and respectively squeeze the two clamping rods 2111, so that the ends of the two clamping rods 2111 move away. At this time, the guiding needle 140 loses the clamping effect of the two clamping rods 2111 and can fall off between the two clamping rods 2111 under the action of gravity.

[0141] The two return needle ejector rods 290 are spaced apart, and the reset structure may further include a magnet disposed between the two return needle ejector rods 290, so as to facilitate attracting the guiding needle 140 through the magnet, so that the guiding needle 140 can fall between the two return needle ejector rods 290.

[0142] In addition, the reset structure may further include a lower cover buckle 252 disposed in the lower cover 250. Correspondingly, the module bracket 120 is provided with a buckling structure 127. When the lower cover 250 is assembled with the outer shell 240, the lower cover buckle 152 can also overlap on the upper end surface of the buckling structure 127 and abut against the buckling structure 127. At this time, the module bracket 120 is not only relatively fixed with the inner sleeve 220, but also relatively fixed with the lower cover 250.

[0143] Referring together to Figure 14 and Figure 20When the lower cover 250 is separated from the outer shell 240 again, during the process of pulling down the lower cover 250, the lower cover buckle 152 presses down the buckling structure 127, so that the top rib 221 is separated from the first bracket buckle 124, and the module bracket 120 falls off the inner sleeve 220. At this time, the guiding pin 140 falls into the lower cover 250, and the module bracket 120 also falls into the lower cover 250, thus realizing the recovery of the module bracket 120 and the guiding pin 140.

[0144] Alternatively, in some embodiments, referring to Figure 21 there is a first gear position and a second gear position between the button module 260 and the outer shell 240. When the button module 260 and the outer shell 240 are in the first gear position, the button module 260 can be used to drive the first limiting structure 202 to switch from the limiting state to the unlocking state. When the button module 260 and the outer shell 240 are in the second gear position, the button module 260 can be used to drive the clamping assembly 211 to switch from the clamping state to the non-clamping state.

[0145] Specifically, the button module 260 may further include a button limiting rib 263, and the button limiting rib 263 is arranged on the button body 261. A button limiting platform 244 may be arranged on the inner wall of the outer shell 240. When the button module 260 and the outer shell 240 are in the first gear position, the button limiting platform 244 is directly opposite to the button limiting rib 263, and the button limiting platform 244 is located directly below the button limiting rib 263. When pressing down the button body 261, the moving distance of the button body 261 is limited to the distance between the button limiting rib 263 and the button limiting platform 244, that is to say, the movable distance of the button body 261 is short.

[0146] The outer shell 240 can also rotate relative to the main bracket 230 around the axis of the main bracket 230. When the outer shell 240 rotates, the relative position between the button limiting platform 244 and the button limiting rib 263 can be changed. When the outer shell 240 rotates to be in the second gear position with the button module 260, the button limiting platform 244 and the button limiting rib 263 are arranged in a staggered manner in the circumferential direction of the outer shell 240, that is, during the downward movement of the button body 261, the button limiting platform 244 will not contact the button limiting rib 263.

[0147] On this basis, the key module 260 may further include a key ejector rod 264. The key ejector rod 264 is connected to the key body 261 and extends along the axial direction of the inner sleeve 220. When the housing 240 and the key module 260 are in the second gear position, the downward movement distance of the key body 261 is not limited by the key limiting platform 244 and can move downward a greater distance. During this process, the key ejector rod 264 can pass through the overlapping portion 2021 and extend between the two clamping rods 2111. After the key ejector rod 264 contacts the clamping rod 2111, during the continuous downward movement of the key body 261, the key ejector rod 264 can squeeze the clamping rod 2111, causing the clamping rod 2111 to rotate relative to the return needle bracket 210, and further causing the clamping assembly 211 to switch from the clamped state to the unclamped state, so that the guide needle 140 can fall off.

[0148] To facilitate the relative fixation of the housing 240 and the main bracket 230 in the direction perpendicular to the axis of the main bracket 230, exemplarily, referring to Figure 22 , a first annular buckle 241 may be provided on the inner wall of the housing 240, and a second annular buckle 231 may be provided on the outer wall of the main bracket 230. The first annular buckle 231 may abut against the lower part of the second annular buckle 241, so that the housing 240 and the main bracket 230 can be relatively fixed. When the housing 240 rotates relative to the main bracket 230, the first annular buckle 241 and the second annular buckle 231 always remain in contact, so as to ensure that the housing 240 will not fall off the main bracket 230.

[0149] In addition, two indication marks may be provided on the surface of the housing 240. One indication mark is used to indicate that the housing 240 and the key bracket are in the first gear position, and the other indication mark is used to indicate that the housing 240 and the key bracket are in the second gear position. In this way, when the housing 240 is manually rotated, the indication marks can be used as a reminder to ensure that the housing 240 is rotated in place.

[0150] It should be noted that when the key ejector rod 264 is provided, the key ejector rod 264 is used to retract the guide needle 140. On this basis, when separating the module bracket 120 from the inner sleeve 220, the elastic wall 123 can also be manually squeezed inward to separate the top rib 221 from the first bracket buckle 124, so as to realize the separation of the module bracket 120 and the inner sleeve 220. Alternatively, a lower cover buckle 252 may be provided in the lower cover 250, and the lower cover buckle 252 is used to engage with the engaging structure 127 of the module bracket 120 to realize the recycling of the module bracket 120.

[0151] Based on the specific structures of the reusable auxiliary implantation device 200 and the sensor module 100 in the above embodiments, when implanting the sensor device 130 disposed in the sensor module 100 into the user's skin using the reusable auxiliary implantation device 200, the following steps may be specifically referred to.

[0152] First, as Figure 23 and Figure 24 shown, open the lid 112 of the sensor module 100 and remove the lower cover 250 of the reusable auxiliary implantation device 200.

[0153] Next, as Figure 16 and Figure 17 shown, assemble the reusable auxiliary implantation device 200 without the lower cover 250 onto the bottom shell 111 of the sensor module 100 from top to bottom. During this process, the sleeve limiting rib 222 of the inner sleeve 220 can be embedded into the upper limiting groove 126 on the module bracket 120 to achieve positioning.

[0154] In this state, the inner sleeve 220 and the main bracket 230 are in a relatively movable state. Therefore, after the sleeve limiting rib 222 is embedded into the limiting groove 126, the outer shell 240 can be pressed downward so that the outer shell 240 drives the main bracket 230 to move downward together and compress the main spring 270. After the main spring 270 is compressed, it can drive the inner sleeve 220 to move downward, causing the top rib 221 of the inner sleeve 220 to squeeze the first bracket buckle 124 on the module bracket 120, and the first bracket buckle 124 disengages from the clamping structure 1111 of the bottom shell 111. At the same time, the top rib 221 abuts against the first bracket buckle 124 to fix the module bracket 120 and the inner sleeve 220. And during this process, since the return needle bracket 210 is relatively fixed to the inner sleeve 220, when the module bracket 120 and the inner sleeve 220 are fixed, the clamping assembly 211 on the return needle bracket 210 clamps the guiding needle 140.

[0155] As Figure 14 shown, after the module bracket 120 and the inner sleeve 220 are fixed, the outer shell 240 and the main bracket 230 continue to move downward, which can make the first sleeve buckle 2022 of the inner sleeve 220 abut against the surface of the overlapping portion 2021 of the main bracket 230, thereby realizing the fixation of the inner sleeve 220 and the main bracket 230.

[0156] Next, since the module bracket 120 and the bottom shell 111 have been separated, when picking up the reusable auxiliary implantation device 200, the bottom shell 111 will naturally fall off, and the module bracket 120 and the sensor device 130 will remain on the inner sleeve 220.

[0157] Next, as Figure 25As shown, the reusable auxiliary implant device 200 fixed with the module support 120 and the sensor device 130 is placed on the user's skin surface, and the button body 261 is pressed downward, and the button body 261 pushes the first sleeve buckle 2022 of the inner sleeve 220 against the overlap portion 2021, so that the inner sleeve 220 and the main support 230 are released from the fixed state. Before this, since the main spring 270 is in a compressed state, at this time, the main spring 270 can push the inner sleeve 220 to drive the module support 120 to move downward, so that the guide needle 140 with the sensor device 130 pierces the user's skin.

[0158] When the main spring 270 pushes the inner sleeve 220 downward to the bracket hook 232 of the main bracket 230, the second sleeve buckle 2011 of the inner sleeve 220 pushes open the return needle buckle 2012 on the return needle bracket 210, thereby releasing the return needle bracket 210 and the inner sleeve 220 from the fixed state.

[0159] like Figure 26 As shown, since the return needle bracket 210 is relatively fixed to the inner sleeve 220, the return needle spring 280 is in a compressed state. At this time, the return needle spring 280 can push the return needle bracket 210 to move upward, while pulling the guide needle 140 out of the user's skin and leaving the sensor 133 in the user's body.

[0160] Due to the dual effects of the user's body and the main spring 270, the inner sleeve 220 is relatively fixed under the abutment of the second sleeve buckle 2011 and the bracket hook 232. At this time, the main spring 270 has a downward pressing force on the inner sleeve 220, so that the application tape 136 at the bottom of the sensor device 130 will stick to the surface of the human body. When the reusable auxiliary implant device 200 is removed upward, the forward buckle 121 is disengaged from the forward slot 1301, so that the module bracket 120 is separated from the sensor device 130, and the sensor device 130 is left in the human body, while the module bracket 120 is left on the inner sleeve 220.

[0161] Next, the lower cover 250 of the reusable auxiliary implantation device 200 is installed on the housing 240 again, and the lower cover buckle 252 on the lower cover 250 is buckled with the buckling structure 127 of the module bracket 120. Then, the lower cover 250 is removed, and the lower cover 250 can take the module bracket 120 away together.

[0162] like Figure 27 As shown, when a return pin push rod 290 is provided in the bottom shell 111 , when the lower cover 250 is closed on the outer shell 240 , the return pin push rod 290 will open the two clamping rods 2111 , so that the guide needle 140 naturally falls into the bottom shell 111 .

[0163] like Figure 21As shown, when the key push rod 264 is set on the key module 260, the housing 240 can be rotated relative to the main bracket 230, so that the housing 240 and the key module 260 are in the second gear, and then the key body 261 is pressed again, so that the key body 261 moves down a longer distance. In this process, the key push rod 264 will open the two clamping rods 2111, so that the guide needle 140 falls naturally.

[0164] Finally, if Figure 28 As shown, the lower cover 250 is again covered on the housing 240, and at this time, the reusable auxiliary implant device 200 is restored to the state before it is used. When it is used next time, just follow the above steps again.

[0165] It can be seen that in the embodiment of the present application, the reusable auxiliary implant device 200 and the sensor module 100 are designed as two independent structures. When in use, the module bracket 120 and the inner sleeve 220 are assembled. After use, the module bracket 120 is removed from the inner sleeve 220 using the lower cover 250 or the key module 260, so as to achieve the reuse of the reusable auxiliary implant device 200, thereby reducing product costs and protecting the environment.

[0166] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
