Description

Technical Field

[0001] The utility model relates to the technical field of biosensors, in particular to an implant component of an implantable biosensor. Background Art

[0002] For the diabetic population, traditional fingertip blood glucose meters have shortcomings such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations and provide warnings. They can no longer meet the needs of some people, especially type 1 diabetes patients who have real-time transmission requirements for blood glucose fluctuations and type 2 diabetes patients who require intensive insulin treatment.

[0003] Due to the need for continuous blood glucose monitoring, the implantable biosensor's implant components and internal components are used to implant the sensor into the human subcutaneous tissue. Measuring the blood glucose concentration between tissue fluids is a continuous monitoring method that can be used in reality. Its single service life is one to two weeks, which greatly reduces the pain caused by the process of continuous fingertip blood sampling and venous blood sampling. Currently, such implantable devices on the market have problems such as complex user operation, long implantation process, and easy mis-triggering of the push device, which leads to reduced user compliance (Patient compliance / Treatment compliance, also known as compliance, refers to the patient's behavior of taking treatment according to the doctor's prescription and consistent with the doctor's orders. It is customary to call the patient "cooperation"; otherwise it is called non-compliance) and experience.

[0004] The transmitter (a device containing implantable sensing electrodes for transmitting monitored biological signals) has a small structure and volume, which helps to improve the wearing experience. The implantable sensing electrodes of the transmitter need to be implanted subcutaneously in the human body. During the assembly process, transportation process and implantation process, the fixed seat and the sliding seat of the transmitter need to be kept relatively fixed at appropriate times and slide relative to each other under certain conditions to achieve the implantation of the implantable sensing electrode and the withdrawal of the implantation needle. With current technology, the coordination between the fixed seat and the sliding seat of the transmitter is not reasonable, and the anti-trigger mechanism is not good. Utility Model Content

[0005] In view of the above, the utility model provides an implantable biosensor implant component, which can avoid false triggering during transportation and has high reliability.

[0006] An implantable biosensor implant assembly includes a main housing, a sliding seat, a fixing seat and an anti-trigger sleeve. The main housing, the sliding seat and the fixing seat cooperate to complete the subcutaneous implantation of an implantable sensing electrode of an implantable biotransmitter.

[0007] When the factory assembly is completed, the upper part of the anti-trigger sleeve is sleeved on the outer side of the main shell, and the lower part of the anti-trigger sleeve is sleeved on the outer side of the upper part of the host protective sleeve. The upper top surface and the lower bottom surface of the anti-trigger sleeve are respectively against the lower peripheral step surface of the main shell and the upper peripheral step surface of the host protective sleeve, and the anti-trigger sleeve limits the movement of the main shell relative to the host protective sleeve.

[0008] When the factory assembly is completed, the anti-trigger sleeve is clamped between the main shell and the host protective sleeve; in the first stage before implantation, the anti-trigger sleeve is removed first, and the main shell can move relative to the host protective sleeve; the main shell drives the implantable bio-transmitter host part to approach the sensing electrode assembly through the fixing seat, completing the clamping of the implantable bio-transmitter host part and the implantable sensing electrode.

[0009] Preferably, the anti-trigger sleeve is elastic and is in the shape of an open circular ring and can be elastically opened.

[0010] Preferably, more than one pin structure is provided inside the anti-trigger sleeve;

[0011] The host protective cover extends upwards by more than one first arc-shaped fence, and the first arc-shaped fence is provided with a first square hole. The lower part of the main shell extends downwards by more than one second arc-shaped fence, and the second arc-shaped fence is provided with a second long arc square hole. When the factory assembly is completed, the pin structure is sequentially inserted into the first square hole and the second long arc square hole, and the pin structure prevents the main shell from moving up and down relative to the host protective cover. When implanted, the anti-trigger cover is removed, and the pin structure loses the function of preventing the main shell from moving up and down relative to the host protective cover.

[0012] Preferably, the number of pin structures is three, the number of first arc-shaped fences is three, and the number of second arc-shaped fences is three, and each pin structure corresponds to a first arc-shaped fence and a second arc-shaped fence respectively.

[0013] The three first arc-shaped fences are evenly distributed on the upper part of the host protection cover.

[0014] Preferably, more than two groups of positioning bosses are arranged on the outer side of the lower part of the main housing, and the number of positioning bosses in each group of positioning bosses is 2;

[0015] The two positioning protrusions in each group are respectively clamped on both sides of two adjacent first arc-shaped fences, and the positioning protrusions prevent the main shell from rotating relative to the host protective cover.

[0016] Preferably, a top column is provided on one side of each group of positioning bosses, and the lower end surface of the top column abuts against the upper top surface of the main unit protective cover.

[0017] The first arc-shaped fence extends out in the shape of a cantilever beam and has elastic deformation capability; there is a complete circular shell structure on the outer side of the lower part of the main shell, and the lower part of the circular shell structure is the second arc-shaped fence, which extends out in the shape of a cantilever beam and has elastic deformation capability; after removing the anti-trigger cover, the pressing action causes the upper top surface of the main protective cover to deform outward, breaking away from the constraint of the lower end surface of the top column, so that the main shell moves downward relative to the main protective cover.

[0018] Preferably, a positioning auxiliary protrusion extends inwardly from the lower portion of the first square hole of the first arc-shaped fence;

[0019] After the anti-trigger cover is removed and the main shell moves downward relative to the host protective cover, the positioning auxiliary protrusion is inserted into the second long arc square hole, and the positioning auxiliary protrusion limits the main shell from moving further downward relative to the host protective cover. The second long arc square hole extends circumferentially for a certain arc length. At this time, the main shell rotates relative to the host protective cover, and the positioning auxiliary protrusion rotates circumferentially along the second long arc square hole, completing the rotational connection between the implantable bio-emitter host part in the main shell and the implantable sensing electrode.

[0020] Preferably, a third hole is provided at the lower part of the second long arc square hole, and when the factory assembly is completed, the positioning auxiliary protrusion is inserted into the third hole.

[0021] Preferably, the two sides of the opening of the anti-trigger sleeve extend out of the inner limit bone position, and the arc-shaped shell at the lower part of the main shell is vertically provided with two rectangular grooves;

[0022] When the factory assembly is completed, the two limit bone positions are respectively inserted into a rectangular groove to prevent the main shell from rotating relative to the main body protective cover.

[0023] Preferably, when the factory assembly is completed, the lower end surface of the limit bone is against the top end surface of the host protective cover.

[0024] Preferably, the lower peripheral side of the fixing seat is used for clamping the implantable biological transmitter, the partition wall of the fixing seat extends upwardly a cantilever hook beam and a support frame, the number of the cantilever hook beams is more than two, the partition plate of the sliding seat is provided with more than two first notches, a clamping frame and a fixing seat extension groove, the number of the first notches is more than two;

[0025] The support frame extends from the card-joining frame, and the support frame can be slidably arranged along the card-joining frame; the partition plate on the outer side of the first notch extends the vertical card plate upward, and the first notch is located at the side of the slot extending from the fixed seat; the upper end of the cantilever hook beam extends the first card protrusion outward; a gap is arranged between the inner side of the cantilever hook beam and the support frame, and a gap is arranged between the outer side of the cantilever hook beam and the vertical part of the vertical card plate; before use after leaving the factory: the upper wall surface of the partition wall abuts against the bottom wall surface of the partition plate, and the fixed seat cannot move upward relative to the sliding seat; the cantilever hook beam extends from the first notch, and a part of the first card protrusion is clamped on the upper end of the vertical card plate, and the fixed seat cannot move downward relative to the sliding seat;

[0026] When in use, the lower end surface of the sliding seat presses against the skin, the fixed seat is subjected to a downward thrust, the cantilever hook beam tends to move downward with the fixed seat, the lower end surface of the first clamping protrusion begins to squeeze the upper end surface of the vertical clamping plate, and under the reaction force of the upper end surface of the vertical clamping plate, the upper end of the cantilever hook beam deforms inward and upward relative to its bottom, and the first clamping protrusion gradually breaks away from the support of the upper end surface of the vertical clamping plate; further downward thrust is applied to the fixed seat, the inner vertical surface of the vertical clamping plate pushes the first clamping protrusion inward, and the fixed seat moves downward relative to the sliding seat.

[0028] The question of how much the first latch is stuck on the upper end of the vertical clamping plate is to what extent it can be pushed open, which we call the interference. When it can be pushed open, a smaller interference requires a smaller trigger force, and a larger interference requires a larger trigger force. By controlling the appropriate interference, a structure that meets the required trigger force value can be designed; if the interference is large to a certain extent, the vertical clamping plate cannot push open the cantilever hook beam, and a jamming situation occurs, and it cannot be pushed open; if the interference is small to a certain extent, under the action of mechanical disturbance or vibration, the vertical clamping plate can push open the restraint of the cantilever hook beam, and it cannot play a locking role in this state.

[0037] When in use, after the fixed seat moves downward a certain distance relative to the sliding seat, the needle auxiliary piece completes the implantation action, the cantilever pressure contact beam separates from the pressure contact of the pressure contact plate, and under the action of the elastic potential energy of the compression spring, the needle-carrying piece pushes open the pressure contact head, and the inner clamping claw of the needle-carrying piece drives the needle auxiliary piece to move upward to complete the needle withdrawal.

[0050] When the transmitter is placed inside the implant component, it is in working or silent state. However, no matter which of the above methods is used, the transmitter and the sensor component have been electrically connected.

The upper top surface and the lower bottom surface of the anti-trigger cover 14 respectively abut against the lower peripheral step surface of the main shell 3 and the upper peripheral step surface of the host protective cover 16, and the anti-trigger cover 14 limits the movement of the main shell 3 relative to the host protective cover 16.

[0077] When the factory assembly is completed, the anti-trigger cover 14 is clamped between the main housing 3 and the host protective cover 16;

[0078] In the first stage before implantation, the anti-trigger cover 14 is removed first, and the main housing 3 can move relative to the host protective cover 16;

[0079] The main housing 3 drives the host part of the implantable bio-transmitter 10 relative to the sensing electrode assembly 02 through the fixing seat 7.

[0080] The implantable bio-emitter 10 host part and the implantable sensing electrode 022 are connected together.

[0085] During implantation, the anti-trigger sleeve 14 is removed, and the pin structure 145 loses the function of preventing the main housing 3 from moving up and down relative to the main body protective sleeve 16.

[0086] In this embodiment, the number of the pin structures 145 is three, the number of the first arc-shaped fences 165 is three, and the number of the second arc-shaped fences 35 is three. Each pin structure 145 corresponds to a first arc-shaped fence 165 and a second arc-shaped fence 35, respectively.

The partition wall 71 of the fixed seat 7 extends upwardly a cantilever hook beam 711 and a support frame 712. The number of the cantilever hook beams 711 is more than two, and the two cantilever hook beams 711 are arranged on opposite sides of the partition wall 71. The cavity plate 61 of the sliding seat 6 is provided with more than two first notches 611, a clamping frame 612 and a fixed seat extension groove 614. The clamping frame 612 constitutes the upper part of the fixed seat extension groove 614. The fixed seat extension groove 614 is opened in the middle position of the cavity plate 61. The clamping frame 612 is on the peripheral side of the fixed seat extension groove 614. The number of the first notches 611 is more than two, and the first notches 611 correspond to the number of the cantilever hook beams 711.

[0102] The support frame 712 extends from the clamping frame 612 , and the support frame 712 is slidably disposed along the clamping frame 612 ;

[0103] The cavity partition plate 61 outside the first notch 611 extends a vertical clamping plate 613 upward, and the first notch 611 is located on the side of the extending groove 614 of the fixing seat;

[0104] The upper end of the cantilever hook beam 711 extends outwardly to form a first locking protrusion 7111;

[0105] A gap is provided between the inner side of the cantilever hook beam 711 and the support frame 712, and a gap is provided between the outer side of the cantilever hook beam 711 and the vertical part of the vertical clamping plate 613. In addition to the partition wall fixedly connected to the fixing seat 7 at the bottom, the cantilever hook beam 711 has movable space in the front, back, left and right directions at the top;

[0106] Before use after leaving the factory: the support frame 712 of the fixed seat 7 passes through the fixed seat extension groove 614 from the lower part of the sliding seat 6, the upper wall surface of the partition wall 71 of the fixed seat 7 abuts against the bottom wall surface of the partition plate 61, and the fixed seat 7 cannot move upward relative to the sliding seat 6; the cantilever hook beam 711 extends from the first notch 611, and the first clamping protrusion 7111 is partially clamped on the upper end of the vertical clamping plate 613, and the fixed seat 7 cannot move downward relative to the sliding seat 6; the amount of the first clamping protrusion 7111 partially clamped on the upper end of the vertical clamping plate 613 is designed according to needs, with strong designability, good controllability, wide design range, and high structural reliability;

[0107] When implanted, the lower end surface of the sliding seat 6 is against the skin, the fixed seat 7 is subjected to a downward thrust, and the cantilever hook beam 711 tends to move downward with the fixed seat 7. The lower end surface of the first clamping protrusion 7111 begins to squeeze the upper end surface of the vertical clamping plate 613. Under the reaction force of the upper end surface of the vertical clamping plate 613, the upper end of the cantilever hook beam 711 is deformed inward and upward relative to its bottom, and the first clamping protrusion 7111 gradually breaks away from the support of the upper end surface of the vertical clamping plate 613; further downward thrust is applied to the fixed seat 7, and after deformation to a certain extent, the first clamping protrusion 7111 breaks away from the support of the upper end surface of the vertical clamping plate 613, and the inner vertical surface of the vertical clamping plate 613 pushes the first clamping protrusion 7111 inward, and the downward movement of the fixed seat 7 relative to the sliding seat 6 is no longer hindered, and the implantation needle is implanted into the skin along with the fixed seat 7 carrying the implantable sensing electrode.

[0108] The lower part of the partition plate 61 is the fixed seat accommodating chamber 62, which accommodates the bottom cavity of the fixed seat 7. The fixed seat accommodating chamber 62 extends inwardly with different lengths of the clamping fingers 621, and the vertical direction of the clamping fingers 621 does not extend to the bottom of the fixed seat accommodating chamber 62. The bottom of the fixed seat 7 is the transmitter accommodating chamber 74. The main part of the implantable biological transmitter 10 is clamped inside the transmitter accommodating chamber 74. The transmitter accommodating chamber 74 is composed of several arc-shaped cantilever clamping beams 741 with different arc lengths. Before implantation, the clamping fingers 621 push the arc-shaped cantilever clamping beams from the outside. 741, the arc-shaped cantilever clamping beam 741 can clamp the implantable bio-emitter 10. When the arc-shaped cantilever clamping beam 741 moves down to a certain extent relative to the fixing seat accommodating cavity 62, the outer side of the arc-shaped cantilever clamping beam 741 is no longer pushed by the clamping finger 621, and can be deformed outward, losing the clamping effect on the implantable bio-emitter 10. After the double-sided tape 1014 on the lower end surface of the implantable bio-emitter 10 sticks to the skin, the implantable bio-emitter 10 also sticks to the skin, and the sliding seat 6 and the fixing seat 7 are withdrawn to complete the needle withdrawal action, and the implantable bio-emitter will not be taken away.

[0109] In this embodiment, the first latching protrusion 7111 is partially clamped on the upper end of the vertical clamping plate 613: the lower flat plane of the first latching protrusion 7111 is pressed on the upper flat plane of the vertical clamping plate 613, and 30% to 90% of the extended length of the first latching protrusion 7111 is clamped on the upper end of the vertical clamping plate 613.

[0110] The first latching protrusion 7111 is stuck on the upper end of the vertical clamping plate 613, which is a question of how much it can support, which we define as the interference. When it can be pushed open, a smaller interference requires a smaller trigger force, and a larger interference requires a larger trigger force. By controlling the appropriate interference, a structure that meets the required trigger force value can be designed; if the interference is large to a certain extent, the vertical clamping plate 613 cannot push open the cantilever hook beam 711, and a jamming situation occurs, and it cannot be pushed open; if the interference is small to a certain extent, under the action of mechanical disturbance or vibration, the vertical clamping plate 613 can push open the restraint of the cantilever hook beam 711, and it cannot play a locking role in this state.

[0116] During use, after the fixed seat 7 moves downward for a distance relative to the sliding seat 6, the auxiliary needle piece 11 completes the implantation action. After the implantable sensing electrode is implanted into the subcutaneous tissue, the cantilever pressure contact beam 7122 is separated from the pressure contact of the pressure contact plate 6122, and the pressure contact head 71221 of the pressure contact plate 6122 no longer presses on the inclined surface on the side of the needle piece 4. The upper part of the needle piece 4 loses its restraint, and under the action of the elastic potential energy of the compression spring 5, the needle piece 4 pushes open the pressure contact head 71221, and the inner clamping claw 41 of the needle piece 4 drives the auxiliary needle piece 11 to move upward to complete the needle withdrawal.
