[0002] For the diabetic population, traditional fingertip blood glucose meters have disadvantages 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, an invasive biosensor component in an invasive bio-information monitoring device needs to be implanted into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in the tissue fluid is a practical continuous monitoring method. In the prior art, an invasive bio-information monitoring device is provided with an invasive bio-sensor component. Before implantation into the human body, the invasive bio-sensor component needs to maintain good sealing performance to ensure that it is in a sterile state before implantation into the human body. Since the housing of the invasive bio-information monitoring device is a split-type setting, the user can disassemble the housing to remove the invasive bio-sensor component and implant it into the human skin. The split-type setting of the housing reduces the overall sealing of the device, making the invasive bio-sensor component at risk of being contaminated by the external environment. Therefore, improving the sealing performance of the housing structure of the invasive bio-information monitoring device has become an urgent problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to solve the technical problem of how to reduce the thickness of the implantable bioelectrode and the thickness of the connection between the implantable bioelectrode and the product, so as to reduce the overall product thickness and improve the user experience, this embodiment discloses an implantable bioelectrode connection structure, an implantable bioelectrode assembly and an implantable bio-information acquisition device. Please refer to Figures 1 to 12 , Figure 1 This is a schematic diagram of the housing structure of an invasive bio-information monitoring device disclosed in this embodiment, specifically:

[0039] A housing structure of an invasive bio-information monitoring device includes a lower housing 1. An assembly through-hole 11 is provided in the middle of the bottom of the lower housing 1. An annular step 12 and a first curved step 13 are provided at the bottom of the interior of the lower housing 1. The annular step 12 is provided around the assembly through-hole 11, and the first curved step 13 is provided around the annular step 12. The annular step 12 and the first curved step 13 are used to support a drying block 02.

[0040] A cantilever hook beam 14 extends from the upper portion of the first arc-shaped step 13 , and the cantilever hook beam 14 is used to fix the drying block 02 .

[0041] It also includes an upper shell, which is connected to the lower shell 1 through threads; it also includes an invasive biosensor component 04; when the assembly is completed, the invasive biosensor component is stored in the enclosed space formed by the upper shell and the lower shell 1.

[0042] Please refer to the attached Figure 10-12 , and also includes a sealing sleeve holder 01, which passes through the assembly through hole 11 of the lower shell 1 and enters the bottom of the lower shell 1. The upper part of the sealing sleeve holder 01 is clamped to the lower part of the invasive biosensor component, and the lower part of the upper shell is clamped to the upper part of the invasive biosensor component.

[0043] In this embodiment, the cantilever hook beam 14 includes a contact plate 141 connected to the first arc-shaped step 13 ; the upper portions of the contact plates 141 of the three cantilever hook beams 14 extend pressure-contact protrusions 142 toward the assembly through holes 11 .

[0044] In this embodiment, the inner side of the upper surface of the pressure-contact protrusion 142 is chamfered.

[0045] In this embodiment, there are two first curved steps 13, which are arranged opposite each other. Three cantilever hook beams 14 are arranged in a circular array on the upper surfaces of the two first curved steps 13. One cantilever hook beam 14 is provided on the upper surface of the middle portion of one first curved step 13, and two cantilever hook beams 14 are provided on the upper surface of each end of the other first curved step 13. Specifically, the distance between each of the three cantilever hook beams 14 is substantially equal, so that the line connecting the three cantilever hook beams 14 forms an equiangular triangle. The three cantilever hook beams 14 exert even tension on the drying block 02, which is better secured to the bottom of the interior of the lower housing 1.

[0046] In this embodiment, a reinforcing rib 132 is provided at each end of the outer side of the first arc-shaped step 13 with a cantilever hook beam 14; a reinforcing rib 132 is provided in the middle part of the outer side of the first arc-shaped step 13 with two cantilever hook beams 14; the three reinforcing ribs 132 are respectively connected to the inner side wall of the bottom of the lower shell 1.

[0047] In this embodiment, the two reinforcing ribs 132 of a first curved step 13 are symmetrically arranged with the cantilever hook beam 14 located on the same first curved step 13 as the midpoint; and the reinforcing rib 132 of another first curved step 13 is located at the midpoint of the line connecting the two cantilever hook beams 14 of the same first curved step 13.

[0048] In this embodiment, two first limiting slots 131 are provided between the first curved steps 13, and the first limiting slots 131 are arranged opposite to each other. Specifically, one first limiting slot 131 is formed between one end of one first curved step 13 and one end of another first curved step 13, and another first limiting slot is formed between the other end of one first curved step 13 and the other end of the other first curved step 13.

[0049] A third arc-shaped step 134 is provided in each first limiting slot 131 . The third arc-shaped step 134 is connected to the annular step 12 , and the height of the third arc-shaped step 134 is lower than that of the annular step 12 .

[0050] Please refer to the attached Figure 6-Figure 9 The drying block 02 is annular in shape. Two symmetrically arranged secondary steps 027 extend downward from the bottom of the drying block 02. The two secondary steps 027 are respectively inserted into the two first limiting slots 131. The two secondary steps 027 respectively cooperate with the third arc-shaped step 134 and the portion of the annular step 12 to limit the lateral movement of the drying block 02, thereby better fixing the drying block 02 to the bottom of the lower shell 1, absorbing moisture inside the lower shell 1, and further improving the internal sealing of the invasive bio-information monitoring device.

[0051] Specifically, a second reinforcing rib 021 extends upward from the circumferential side of the inner ring of the drying block 02, a third reinforcing rib 022 extends upward from the circumferential side of the outer ring of the drying block 02, and a plurality of fourth reinforcing ribs 023 extend upward from the upper surface of the drying block 02. The fourth reinforcing rib 023 connects the second reinforcing rib 021 and the third reinforcing rib 022. The plurality of fourth reinforcing ribs 023 are arranged in a divergent shape toward the outer ring with the center of the inner ring of the drying block 02 as the midpoint. The plurality of fourth reinforcing ribs 023 divide the groove between the third reinforcing rib 022 and the second reinforcing rib 021 into a plurality of drying grooves 024. Through the cooperation between the second reinforcing rib 021, the third reinforcing rib 022 and the upper surface of the drying block 02, a plurality of drying grooves 024 are formed on the upper surface of the drying block 02, thereby increasing the contact area between the drying block 02 and the air, so that the drying block 02 can absorb more water vapor in the invasive bio-information monitoring device. If there is too much water vapor, it can be stored in the drying grooves 024, limiting the range of water vapor flow, reducing the risk of environmental pollution inside the device, and further improving the internal sealing of the invasive bio-information monitoring device.

[0052] Specifically, a fifth reinforcing rib 026 extends downward from the lower peripheral side of the drying block 02, and three snap-in grooves 0261 are provided at the lower part of the fifth reinforcing rib 026. The positions of the three snap-in grooves 0261 correspond to the three reinforcing ribs 132 respectively, and the bottom wall of each snap-in groove 0261 is chamfered. When the drying block 02 is fixed to the bottom inside the lower shell 1, the three reinforcing ribs 132 are respectively inserted into the three snap-in grooves 0261, so that the drying block 02 is further fixed to the bottom inside the lower shell 1.

[0053] Specifically, a cantilever through hole 025 is provided in each of the three drying grooves 024, and a pressure touch plate 0251 is provided on the side of each cantilever through hole 025 close to the inner ring of the drying block 02. The positions of the three cantilever through holes 025 correspond to the positions of the three cantilever hook beams 14 respectively; the pressure touch plates 0251 are respectively connected to the two side walls of the drying groove 024.

[0054] Please refer to the attached Figure 8 and attached Figure 9 The cantilever hook beam 14 passes through the cantilever through-hole 025, and the pressure-touch protrusion 142 presses on the upper surface of the pressure-touch plate 0251, so that the cantilever hook beam 14 hooks the drying block 02 through the cantilever through-hole 025, so that the drying block 02 is fixed to the bottom inside the lower shell 1, so that the internal environment of the invasive bio-information monitoring device is stable; when the drying block 02 is placed at the bottom inside the lower shell 1, the third reinforcing rib 022 surrounds the outer peripheral sides of the two first arc-shaped steps 13, further fixing the drying block 02 to the bottom inside the lower shell 1.

[0055] In this embodiment, two second arc-shaped steps 111 are provided on the inner wall of the assembly through hole 11, and the second arc-shaped steps 111 are arranged opposite to each other; a second limiting slot 112 is provided between the two ends of the two second arc-shaped steps 111, and the upper parts of the two second limiting slots 112 extend out of the second arc-shaped steps 111 respectively.

[0056] In this embodiment, the two second limiting slots 112 are respectively located on the connecting line of the two first limiting slots 131 .

[0057] Specifically, a supporting column 012 is provided on the upper surface of the fixing plate 011, and two snap-fitting protrusions 013 extend outward from the peripheral side of the supporting column 012. The two snap-fitting protrusions 013 are respectively placed in the two second limiting slots 112 to facilitate assembly.

[0058] Please refer to the attached Figure 10-12 The bottom of the first arc-shaped step 13 is respectively provided with an arc-shaped groove 133, and the arc-shaped groove 133 is used for interference fit with the screw.

[0059] An annular groove 121 is provided at the bottom of the annular step 12 , and the annular groove 121 is used for clamping the sealing ring 03 .

[0060] In this embodiment, there is a height difference between the annular step 12 and the first curved step 13; specifically, the annular step 12 is lower than the first curved step 13. An annular groove 121 is provided at the bottom of the annular step 12, and an arcuate groove 133 is provided at the bottom of the first curved step 13. The depth of the arcuate groove 133 is greater than the depth of the annular groove 121, so the annular step 12 is lower than the first curved step 13.

[0061] Specifically, the annular groove 121 is used to clamp the sealing ring 03. When the sealing sleeve holder 01 extends into the assembly through hole 11 and enters the interior of the lower shell 1, the sealing ring 03 is squeezed between the annular groove 121 and the sealing sleeve holder 01, so that the lower shell 1, the upper shell 2, the sealing sleeve holder 01, and the sealing ring 03 form a closed space;

[0062] Specifically, the arc groove 133 is used to clamp the external screws. A fixing plate 011 extends from the bottom peripheral side of the sealing sleeve holder 01. The fixing plate 011 is provided with screw holes. The fixing plate 011 is fastened to the bottom of the lower shell 1 by screws.

[0063] Specifically, the annular groove 121 is arranged on the inner side of the arc groove 133, and correspondingly, the sealing ring 03 is arranged on the inner side of the screw. When the assembly is completed, the lower shell 1 and the sealing sleeve holder 01 are more tightly connected, further improving the internal sealing of the invasive bio-information monitoring device.

[0064] The drying block 02 is fixed to the bottom of the lower shell 1 through the first arc-shaped step 13 and the cantilever hook beam 14, so that the drying block 02 can absorb water vapor inside the main shell of the invasive biological information monitoring device, further improving the internal sealing of the invasive biological information monitoring device.

[0065] The first curved step 13 is connected to the inner side wall of the bottom of the lower shell 1 by three reinforcing ribs 132, which strengthens the structural stability of the first curved step 13, making the structure of the lower shell 1 more stable and not easily damaged by squeezing during the assembly process or the process of the drying block 02 absorbing water and expanding, thereby further improving the internal sealing of the invasive bio-information monitoring device.

[0066] Through the cooperation between the first limiting slot 132 and the drying block 02, the drying block 02 is arranged in a ring shape, and two symmetrically arranged secondary steps 021 extend downward from the bottom of the drying block 02. The two secondary steps 021 are respectively inserted into the two first limiting slots 131, limiting the lateral movement of the drying block 02, so that the drying block 02 is better fixed to the bottom of the lower shell 1, absorbing water vapor inside the lower shell 1, and further improving the internal sealing of the invasive bio-information monitoring device.

[0067] Through the cooperation of the arc groove 133 and the annular groove 121 with the sealing ring 03 and the external screws, the sealing sleeve holder 01 can be fastened to the lower part of the lower shell 1, further improving the internal sealing of the invasive biological information monitoring device.

[0068] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
