Description

Technical Field

[0001] This invention belongs to the field of bioinformatics monitoring, and specifically relates to an implantable bioinformatics sensor component. Background Technology

[0002] Implantable bio-information sensor components are core medical devices used for real-time monitoring of physiological parameters in the body. They require subcutaneous implantation via a needle-assisted device. The reliability of the connection between the sensor and the needle-assisted device, as well as the ease of assembly and disassembly, directly determine the efficiency of clinical implantation, the convenience of consumable replacement, and the safety of use. They are widely used in scenarios such as chronic disease management and clinical monitoring.

[0003] Existing connection methods between sensor components and needle aids are mostly complex in structure, cumbersome in assembly steps, unreliable in locking effect, and cannot achieve quick disassembly and assembly when consumables need to be replaced. This not only affects the efficiency of clinical use, but also easily leads to problems such as loose connection and inaccurate positioning, making it difficult to meet the usage requirements of quick disassembly and assembly and stable connection at the same time.

[0004] Therefore, how to design an implantable bioinformatics sensor assembly that enables rapid assembly and disassembly of the sensor and the needle applicator, while ensuring a stable and reliable connection between the two, requiring no additional tools, and offering convenient operation, has become a pressing technical problem to be solved in this field. Summary of the Invention

[0005] Therefore, it is necessary to provide an implantable bioinformation sensor component that can be quickly disassembled and reliably connected, addressing the problems of cumbersome disassembly and assembly and insufficient positioning reliability of existing implantable bioinformation sensor components.

[0006] Embodiments of this application provide an implantable bio-information sensor assembly, comprising: A snap-fit ​​bracket is provided inside the snap-fit ​​bracket, and a snap-fit ​​structure is also provided on the inner side wall of the snap-fit ​​bracket for snap-fitting and fixing the drying block. The guide needle has an insertion portion that passes through the sensor, and the lower middle portion of the guide needle is detachably and securely engaged with the electrode protective cover. The sensor is clamped between the guide pin and the electrode protective cover, and the locking bracket can lock and unlock the guide pin; The outer side of the clip-on bracket is provided with an elastic clip arm. The implantable bio-information sensor assembly can be inserted into and removed from the needle aid nut through the elastic clip arm. The needle aid nut is screwed to the outer side of the bottom of the needle aid. The needle aid can remove the used guide needle through the needle aid nut and replace it with a new implantable bio-information sensor assembly.

[0007] Furthermore, the implantable bio-information sensor assembly also includes a detachable nut; The detachable nut is a lower housing, and a snap-fit ​​cavity is provided inside the lower housing. The snap-fit ​​bracket can snap into and out of the snap-fit ​​cavity.

[0008] Furthermore, the outer side of the electrode protective cover is provided with two guide blocks arranged opposite to each other, the inside of the snap-fit ​​bracket is provided with a sleeve, and the peripheral wall of the sleeve is provided with a limiting groove; The guide block slides in conjunction with the limiting groove, and a push spring is provided inside the sleeve. The push spring is elastically compressed between the sleeve of the clamping bracket and the bottom of the electrode protective cover.

[0009] Furthermore, two screw-in slots are arranged adjacently along the circumferential direction on the inner side of the upper part of the electrode protective cover; The lower locking part of the guide pin is provided with two locking buckles, which can be screwed into the two screw-in slots respectively.

[0010] Furthermore, one of the said screw-in slots includes: a downward spiral ramp section that rotates clockwise in the circumferential direction on the upper top wall, a planar buffer section, and an inwardly extending locking block section; One of the screw-in slots has a locking block limiting section adjacent to and connected to the other screw-in slot's downward spiral ramp section; The two snap-fit ​​buckles are arranged symmetrically at 180° to achieve seamless engagement and disengagement of the two snap-fit ​​buckles into the two screw-in slots respectively.

[0011] Furthermore, the latch is a guide pin with two latching arms extending downwards. The latching arms are provided with an upper latching protrusion and a lower latching protrusion, and a latching opening is formed between the two latching protrusions. The lower locking protrusion is screwed into the screw-in locking groove, and the locking block limiting section is locked into the locking opening to achieve axial positioning of the guide needle and the electrode protective cover; The locking block is a stop structure that protrudes from the end of the planar buffer section. It has a guide slope on one side facing the planar buffer section. The locking buckle can slide in or out along the guide slope. The end face of the locking buckle abuts against the end face of the locking block, thereby achieving circumferential positioning of the guide needle and the electrode protective cover.

[0012] Furthermore, a retaining plate is provided at the lower part of the guide pin, and a sealing gasket is embedded in the retaining plate; After assembly, the sealing gasket is pressed between the guide pin and the electrode protective cover to achieve a seal; The sensor has a through hole, and the insertion part of the guide needle passes through the through hole. Two snap-fit ​​holes are provided on both sides of the through hole, which are respectively snap-fitted with the two upper snap-fit ​​protrusions to fix the sensor to the lower part of the guide needle. The sensor has a stepped hole at the bottom that is adapted to the electrode protective cover. When the guide pin is screwed into the electrode protective cover, the end of the electrode protective cover is engaged in the stepped hole to achieve the clamping and positioning of the sensor between the guide pin and the electrode protective cover.

[0013] Furthermore, the outer side wall of the snap-fit ​​bracket is provided with two elastic snap-fit ​​arms, and the nut is provided with two snap-fit ​​grooves accordingly. By squeezing and pushing in the two elastic locking arms from both sides, the elastic locking arms can be locked in the locking groove, thereby realizing the locking of the locking bracket and the disassembly nut. By squeezing and pulling the two elastic locking arms from both sides, the elastic locking arms can be disengaged from the locking groove, allowing the locking bracket to be pulled out of the disassembly nut.

[0014] Furthermore, the guide needle has two flat-headed latches extending to both sides, and two anti-rotation protrusions are provided below the flat-headed latches; The inner sidewall of the needle seat that mates with the head of the guide needle is alternately provided with two elastic claws and two anti-rotation locking walls along the circumferential direction. The needle seat is provided with a guide positioning groove corresponding to the anti-rotation boss. When the snap-fit ​​bracket is snapped into the disassembly nut and rotated into a preset angle such as 90° relative to the needle aid, it drives the guide needle to rotate relative to the needle seat, so that the flat head buckle engages with the elastic claw and the anti-rotation boss engages with the guide positioning groove, thereby achieving locking. When the nut is rotated out of the needle holder by a preset angle, such as 90°, the guide needle rotates in the opposite direction relative to the needle holder, causing the flat head buckle to disengage from the elastic claw and the anti-rotation boss to disengage from the guide positioning groove, thus unlocking the device.

[0015] Furthermore, the detachable nut is provided with a support part, which is a reinforced support structure with a ramp, and abuts against the ejection mechanism of the needle aid that is detachably connected to the detachable nut; The ramp structure of the support part serves to fix and strengthen the structure, thereby increasing the structural strength of the push-and-reset mechanism. When the nut is screwed into the needle-assist device, the support pushes against the ejection mechanism, causing the ejection mechanism to reset to its initial state before triggering.

[0016] Furthermore, the implantable bio-information sensor assembly also includes a drying block, which is snapped and fixed to the snap-fit ​​structure on the inner side wall of the snap-fit ​​bracket for drying and moisture prevention inside the assembly. The clip bracket is also equipped with a permanent magnet fixing structure for fixing the permanent magnet. A Hall sensor is correspondingly set on the sensor. The permanent magnet and the Hall sensor work together to sense and trigger the component to turn on, so as to realize the function of automatic power-on after implantation.

[0017] In the various embodiments provided in this application, during implantation, the guide needle and electrode protective cover are clamped and fixed, the sensor is clamped and fixed between the two, the snap-fit ​​bracket is snapped into the disassembly nut, and the disassembly nut is rotated out clockwise at a preset angle relative to the needle aid device, causing the guide needle and the needle base of the needle aid device to rotate relative to each other at a preset angle, thereby realizing the snap-fit ​​fixation of the guide needle and the needle base. Continuing to rotate clockwise at a preset angle, the electrode protective cover rotates relative to the guide needle at a preset angle, and the snap-fit ​​buckle is unlocked by screwing into the slot. At this time, the sensor is also released from the snap-fit ​​of the electrode protective cover, the guide needle and the sensor snapped with it are separated from other sensor components, and at the same time, the permanent magnet is disengaged from the Hall sensor on the sensor, triggering the component to start up, and then the guide needle is implanted. After implantation, the disassembly nut and the locking bracket are locked together by the elastic locking arm. The guide needle is simultaneously locked to the needle seat of the assist device. Then, the disassembly nut is screwed in counterclockwise at a preset angle relative to the assist device. The support part of the disassembly nut pushes against the ejection mechanism of the assist device and moves upward to reset to the initial state to be triggered. The locking buckle of the guide needle is screwed into the screw-in slot of the electrode protective cover, and the guide needle and the electrode protective cover are locked together. Continue to rotate counterclockwise at a preset angle. The disassembly nut drives the guide needle to rotate relative to the needle seat at a preset angle, and the guide needle and the needle seat are unlocked. At this time, the locking bracket can be removed from the disassembly nut, and a new sensor component can be replaced for reuse, which facilitates the quick replacement and maintenance of the sensor.

[0018] Therefore, addressing the problems of cumbersome assembly, unreliable locking, and inconvenient disassembly / removal of existing implantable sensors, this invention adopts a combined structure of a snap-fit ​​bracket, a guide needle, and a sensor. The snap-fit ​​bracket features an electrode protective cover, and the lower snap-fit ​​portion of the guide needle is detachably and sealed to the electrode protective cover. The guide needle insertion portion passes through the sensor, which is clamped between the guide needle and the electrode protective cover. The snap-fit ​​bracket can lock and unlock the guide needle. An elastic locking arm is provided on the outer side of the snap-fit ​​bracket, allowing for quick engagement and disengagement with the disassembly nut of the needle aid. The disassembly nut is screwed to the outer bottom of the needle aid. The needle aid removes the used guide needle through the disassembly nut and replaces it with a new implantable bio-information sensor assembly. This invention achieves rapid disassembly / removal and stable connection between the sensor and the needle aid, making it suitable for implantable bio-information monitoring scenarios. It also enables rapid disassembly / removal and reliable positioning of the implantable bio-information sensor assembly, comprehensively improving the clinical efficiency and ease of operation of the assembly.

[0024] The snap-fit ​​bracket 10 is equipped with an electrode protective cover 40. The lower snap-fit ​​part of the guide needle 20 is detachably and tightly snapped into the electrode protective cover 40. The insertion part of the guide needle 20 is exposed through the sensor 30. The sensor 30 is clamped between the guide needle 20 and the electrode protective cover 40. The snap-fit ​​bracket 10 can lock and unlock the guide needle 20. An elastic snap-fit ​​arm 103 is provided on the outside of the snap-fit ​​bracket 10. The implantable bio-information sensor assembly can be snapped into and out of the removal nut 50 of the needle aid 00 through the elastic snap-fit ​​arm 103. The removal nut 50 is screwed to the bottom outer side of the needle aid 00. The needle aid 00 can remove the used guide needle 20 through the removal nut 50 and replace it with a new implantable bio-information sensor assembly.

[0025] Two screw-in slots 402 are arranged adjacently along the circumferential direction on the upper inner side of the electrode protective cover 40. The lower locking part of the guide pin 20 is provided with two locking buckles 201. The two locking buckles 201 can be screwed into the two screw-in slots 402 respectively to realize the axial and circumferential positioning of the guide pin 20 and the electrode protective cover 40.

[0026] The needle tip of the guide needle 20 is provided with two flat-headed latches 203 extending to both sides, and two anti-rotation protrusions 204 are provided below the flat-headed latches 203; the inner side wall of the needle seat 80 that cooperates with the head of the guide needle 20 is alternately provided with two elastic claws 801 and two anti-rotation latches 802 along the circumference, and the needle seat 80 is provided with a guide positioning groove 803 corresponding to the anti-rotation protrusions 204.

[0027] The sensor 30 has a through hole 301, and the insertion part of the guide needle 20 passes through the through hole 301. Two snap-fit ​​holes 302 are provided on both sides of the through hole 301, which are respectively snap-fitted with two upper snap-fit ​​protrusions 2011 to fix the sensor 30 to the lower part of the guide needle 20. The lower part of the sensor 30 has a stepped hole 303 that is adapted to the electrode protective cover 40. When the guide needle 20 is screwed into the electrode protective cover 40, the end of the electrode protective cover 40 is snapped into the stepped hole 303, realizing the clamping and positioning of the sensor 30 between the guide needle 20 and the electrode protective cover 40.

[0028] Two elastic locking arms 103 are arranged opposite each other on the outer side wall of the snap-fit ​​bracket 10, and two snap-fit ​​grooves 502 are correspondingly provided in the disassembly nut 50. When the two elastic locking arms 103 are pushed in from both sides, the elastic locking arms 103 can be locked in the snap-fit ​​grooves 502, realizing the snap-fit ​​between the snap-fit ​​bracket 10 and the disassembly nut 50. When the two elastic locking arms 103 are pulled out from both sides, the elastic locking arms 103 can be disengaged from the snap-fit ​​of the snap-fit ​​grooves 502, realizing the snap-fit ​​bracket 10 can be pulled out from the disassembly nut 50.

[0029] The following is in conjunction with the appendix Figures 1 to 14 Briefly describe the working process of an implantable bio-information sensor component: When the sensor needs to be implanted, the guide pin 20 is clamped and fixed to the electrode protective cover 40, and the sensor 30 is clamped and fixed between the two. The snap-fit ​​bracket 10 snaps into the disassembly nut 50. At this time, the disassembly nut 50 rotates 90° counterclockwise relative to the needle aid 00, which drives the guide pin 20 and the needle seat 80 of the needle aid 00 to rotate 90° relative to each other, realizing the snap-fit ​​fixation of the guide pin 20 and the needle seat 80. Continue to rotate counterclockwise 90°, and after a total rotation of 180°, the electrode protective cover 40 rotates 90° relative to the guide pin 20. The snap-fit ​​buckle 201 and the screw-in slot 402 unlock the sensor. At this time, the sensor 30 is also released from the snap-fit ​​of the electrode protective cover 40. The guide pin 20 and the sensor 30 snapped with it are separated from other sensor components. At the same time, the permanent magnet 100 is disconnected from the Hall sensor on the sensor 30, triggering the sensor to turn on. Then, the implantation is completed under the action of the needle aid 00.

[0030] When the sensor needs to be disassembled and replaced, the snap-fit ​​bracket 10 is locked and fixed with the disassembly nut 50, and the guide pin 20 is simultaneously locked with the needle seat 80 of the needle aid 00. Then, the disassembly nut 50 is rotated 90° clockwise relative to the needle aid 00. The support part 503 of the disassembly nut 50 pushes against the ejection mechanism 901 of the needle aid 00 and moves upward to reset to the initial state to be triggered. The snap-fit ​​buckle 201 of the guide pin 20 is screwed into the screw-in slot 402 of the electrode protective cover 40, and the guide pin 20 is locked and fixed with the electrode protective cover 40. Continue to rotate 90° clockwise, and after a total rotation of 180°, the disassembly nut 50 drives the guide pin 20 to rotate 90° relative to the needle seat 80, and the guide pin 20 is unlocked from the needle seat 80. At this time, the snap-fit ​​bracket 10 can be removed from the disassembly nut 50, and a new sensor assembly can be replaced and reused, which facilitates the quick replacement and maintenance of the sensor.
