Description

A highly sealed invasive biosensor component and bioinformation monitoring device Technical Field

[0001] This application relates to the field of biosensor technology, and in particular to a highly sealed invasive biosensor component and a bioinformation monitoring device. Background Technology

[0002] For people with diabetes, traditional fingertip blood glucose meters have drawbacks such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations or provide early warnings. They no longer meet the needs of some people, especially type 1 diabetes patients who require real-time transmission of blood glucose fluctuations and type 2 diabetes patients who need intensive insulin therapy.

[0003] Due to the need for continuous blood glucose monitoring, an integrated implantable component of an invasive biosensor is required to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in the tissue fluid is a practical and continuous monitoring method. Its single lifespan is one to two weeks, which greatly reduces the pain caused by continuous finger-prick and venous blood sampling. Currently, such implantable devices on the market have problems such as complicated operation for users, long implantation time, and easy accidental triggering of the push device, which leads to reduced user compliance (Patient compliance / Treatment compliance, also known as compliance or adherence, refers to the behavior of patients following the doctor's treatment and consistent with the doctor's orders, commonly referred to as patient "cooperation"; the opposite is called non-compliance) and experience.

[0004] In the existing technology, there are at least the following technical problems: When the invasive biosensor component and the main control circuit of the transmitter are assembled at the factory, the main control circuit of the invasive biosensor component and the transmitter both need to be produced in a sterile environment, which is highly dependent on the production environment and reduces the efficiency of mass production; if the main control circuit of the invasive biosensor component and the transmitter are made into one piece, the airtightness of the invasive biosensor component is reduced.

[0005] Therefore, improving the internal airtightness of invasive biosensor components and devices used to place invasive biosensor components, and reducing the requirements of the manufacturing environment, in order to improve the reliability of invasive biosensor components and increase production efficiency, has become an urgent technical problem to be solved.

[0034] The invasive biosensor component forms a sealed space inside, maintaining a sealed and sterile state during manufacturing, transportation, and shelf life, thus improving product stability and safety. When mass-producing invasive biosensor components, only the invasive biosensor component itself needs to be manufactured and assembled in a sterile environment, while other components can be manufactured and assembled in a normal production environment.

[0035] During factory assembly, the upper shell, bottom shell, and support base form a sealed space. When the product is not in use, the invasive biosensor component is stored in the sealed space. Only during pre-implantation assembly are the upper shell and bottom shell separated to expose the bioelectrode and guide needle to be implanted. The bioelectrode and guide needle are only exposed to the air when the upper shell and bottom shell are separated, which is a very short time. This reduces the risk of contamination of the bioelectrode and guide needle, improves the safety of the bioelectrode and guide needle implanted in the human body, and further enhances the stability and safety of the product.

Detailed Implementation

[0049] The present application is described below based on embodiments, but the present application is not limited to these embodiments. In the following detailed description of the present application, some specific details are described in detail, but well-known methods, processes, flows, and elements are not described in detail in order to avoid obscuring the substance of the present application.

[0050] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0051] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0052] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0053] To address the issue of poor internal sealing in invasive biosensor components and devices for placing them, this application discloses a highly sealed invasive biosensor component and a highly sealed invasive bioinformation monitoring device. Referring to Figures 1 to 9, Figures 1 and 2 illustrate a highly sealed invasive biosensor component disclosed in this embodiment, including a support structure 1, an electrode plate 2, a bioelectrode 3, a guide pin 4, and a sealing sleeve 5. The bioelectrode 3 includes a signal output electrode 32, a connecting section 31, and a sensing section 33 connected in sequence.

[0054] The electrode pressure plate 2 is pressed against the bottom of the support structure 1, and part of the connecting section 31 is stuck between the support structure 1 and the electrode pressure plate 2;

[0055] The sealing sleeve 5 is snapped onto the outside of the electrode pressure plate 2 and the guide pin 4, and the sealing sleeve 5 is sealed at the bottom of the support structure 1.

[0056] The lower part of the sensing section 33 and the guide pin 4 is sealed inside the sealing sleeve 5; the signal output electrode 32 is disposed on the upper part of the support structure 1.

[0057] The interior of the invasive biosensor component 01 forms a sealed space. The support structure 1, the sealing sleeve 5, and the electrode pressure plate 2 form a sealed space. The sensing segment 33 to be implanted and the lower part of the guide needle 4 are sealed in the sealing sleeve 5. The product is in a sealed and sterile state when it leaves the factory, during product transportation, and on the shelf, which improves the stability and safety of the product.

[0058] Mass production of invasive biosensor components requires the integrated biosensor components to be produced and assembled in a sterile environment, while other components can be produced and assembled in a normal production environment. This reduces the environmental requirements for manufacturing and improves the efficiency of production operations when performing sterile disinfection procedures.

[0059] In this embodiment, the sealing sleeve 5 is sealed at the bottom of the support structure 1 as follows: the support structure 1 is provided with a guide pin through hole 11, and the guide pin 4 passes through the guide pin through hole 11 and extends out of the lower part of the support structure 1.

[0060] The lower part of the needle seat 42 of the guide needle 4 is provided with a reverse groove 41, and part of the edge of the electrode pressure plate 2 extends outward to form an ear-shaped buckle 21. The inner side of the sealing sleeve 5 is provided with two screw-in protrusions 51; one screw-in protrusion 51 is engaged with the ear-shaped buckle 21, and the other screw-in protrusion 51 is engaged with the reverse groove 41.

[0061] Before leaving the factory, one screw-in locking protrusion 51 is engaged with the ear-shaped buckle finger 21, and the other screw-in locking protrusion 51 is engaged with the undercut groove 41;

[0062] During pre-implantation assembly, rotate the sealing sleeve 5, one screw-in locking protrusion 51 is screwed out from the ear-shaped buckle 21, and the other screw-in locking protrusion 51 is screwed out from the undercut groove 41.

[0063] In this embodiment, a sealing ring 43 is sleeved on the lower outer side of the needle seat 42, and the sealing ring 43 is located above the undercut groove 41.

[0064] The outer side of the sealing ring 43 is press-fitted with the guide pin through hole 11, and the outer side of the sealing ring 43 is engaged in the guide pin through hole 11, so that a sealed space is formed between the guide pin through hole 11, the guide pin 4 and the support structure 1.

[0065] Specifically, the sealing ring 43 compresses the inner wall of the guide needle through hole 11 and the outer side of the needle seat 42. The lower part of the guide needle 3 and the sensing section 33 are located in the sealed space formed between the guide needle through hole 11, the guide needle 4, the sealing sleeve 5 and the support structure 1, which further improves the internal sealing of the high-sealing invasive biosensor component 01.

[0066] In this embodiment, a first sealing groove 12 is provided at the lower part of the support structure 1, and the first sealing groove 12 surrounds the electrode pressure plate 2, the bioelectrode 3 and the guide needle 4.

[0067] A first sealing gasket 52 is provided on the upper part of the sealing sleeve 5. The first sealing gasket 52 is pressed between the first sealing groove 12 and the sealing sleeve 5, so that a sealed space is formed between the support structure 1 and the sealing sleeve 5. The electrode pressure plate 2, the sensing section 33, and the guide needle 4 are located in the sealed space formed between the support structure 1 and the sealing sleeve 5, which further improves the internal sealing of the high-sealing invasive biosensor component 01.

[0068] The top of the sealing sleeve 5 is provided with a sealing gasket snap-fit ​​groove. The first sealing gasket 52 is partially squeezed into the sealing gasket snap-fit ​​groove, so that the first sealing gasket 52 can be fixed to the top of the sealing sleeve 5. The sealing gasket snap-fit ​​groove can be filled with glue to improve the connection stability of the first sealing gasket 52 to the sealing gasket snap-fit ​​groove, and further improve the sealing performance of the sealed space between the sealing sleeve 5 and the support structure 1.

[0069] The sealing sleeve 5 forms an engaging structure with the ear-shaped snap finger 21 of the electrode pressure plate 2 and the inverted snap groove 41 of the guide needle 4 by screwing in the snap protrusion 51. The engaging structure allows the sealing sleeve 5 to be firmly snapped into the lower part of the support structure 1. At the same time, by squeezing the sealing sleeve 5 upward, the first sealing gasket 52 is squeezed between the sealing gasket snap groove and the first sealing groove 12 of the support structure 1, which further improves the sealing performance of the sealed space between the sealing sleeve 5 and the support structure 1.

[0070] In this embodiment, a rubber stopper 53 is provided at the lower part of the sealing sleeve 5; the rubber stopper 53 can isolate air and moisture.

[0071] The rubber stopper 53 is inserted into the bottom inner wall of the sealing sleeve 5 to achieve a detachable sealing structure. The bottom of the rubber stopper 53 may partially protrude from the sealing sleeve 5. Specifically, the partial protrusion of the bottom of the rubber stopper 53 provides a certain cushioning effect on the sealing sleeve 5. When external force is applied to the bottom of the sealing sleeve 5 during factory assembly or transportation, the soft texture of the rubber stopper 53 can buffer the external force, making the sealing sleeve less prone to damage and the sealing performance less likely to be compromised.

[0072] Meanwhile, during the assembly process, the rubber plug is inserted into the sealing sleeve 5 in the last step of assembling the component. If the component structure in the previous steps is easy to assemble, the component is not likely to be subjected to too much gas pressure. If the rubber plug 53 is not inserted last, the gas inside the sealing sleeve is likely to be squeezed, making assembly difficult. If the rubber plug 53 and the sealing sleeve 5 are an integrated structure, the installation process of the sealing sleeve 5 is more dangerous and may be at risk of breakage and damage, resulting in unsmooth assembly.

[0073] In this embodiment, a drying block 54 is provided inside the sealing sleeve 5, and an installation groove 531 is provided on the upper surface of the rubber stopper 53, into which the drying block 54 is embedded. In actual production, due to the material limitations of the sealing sleeve 5, the sealing sleeve 5 is not absolutely isolated from external gases and liquids. A small amount of gas and liquid may enter the sealed space formed by the sealing sleeve 5 and the support structure 1 through the sealing sleeve 5, contaminating the bioelectrode 3 and the guide needle 4. Placing the drying block 54 inside the sealing sleeve can further absorb moisture, keeping the inside of the sealing sleeve 5 dry, further improving the sealing performance of the sealed space between the sealing sleeve 5 and the support structure 1, and ensuring good internal environmental stability of the component.

[0074] In this embodiment, the support structure 1 is provided with a connecting section through groove 13, and the bottom of the support structure 1 is provided with an adhesive filling groove 14. The adhesive filling groove 14 is connected to the connecting section through groove 13. The electrode pressure plate 2 is pressed below the connecting section through groove 13 and the adhesive filling groove 14. The connecting section 31 is disposed in the connecting section through groove 13 and the adhesive filling groove 14.

[0075] The upper surface of the electrode pressure plate 2 extends out of the snap-fit ​​post 22, and the lower surface of the support structure 1 is provided with a snap-fit ​​groove 16. The snap-fit ​​post 22 and the snap-fit ​​groove 16 are in clearance fit. The snap-fit ​​post 22 and the snap-fit ​​groove 16 are in clearance fit so that the snap-fit ​​groove 16 can be filled with glue. The glue connects the snap-fit ​​post 22 and the snap-fit ​​groove 16.

[0076] Adhesive is filled into the adhesive filling groove 14 and the snap-fit ​​groove 16, filling the gap between the adhesive filling groove 14, the connecting section 31, the electrode pressure plate 2 and the support structure 1. The adhesive is preferably a thick paste-like colloid, such as UV adhesive. The electrode pressure plate 2 is preferably transparent. After filling the adhesive filling groove 14 and the snap-fit ​​groove 16, the electrode pressure plate 2 is irradiated with ultraviolet light. The ultraviolet light penetrates the electrode pressure plate 2 and irradiates the adhesive. The adhesive is cured after irradiation, thereby forming a sealed structure between the support structure 1, the electrode pressure plate 2 and the connecting section 31.

[0077] The connecting section groove 13 can be filled with glue to further cover the gap between the connecting section 31 and the electrode pressure plate 2 and the connecting section groove 13, thereby improving the sealing between the support structure 1, the electrode pressure plate 2 and the connecting section 31.

[0078] In this embodiment, the support structure 1 is also provided with an arc-shaped groove 15, which connects the glue filling groove 14 and the guide needle through hole 11. The depth of the arc-shaped groove 15 gradually increases from one end of the glue filling groove 14 to one end of the guide needle through hole 11.

[0079] The connecting section 31 is provided with a bending section 311, which connects the connecting section 31 and the sensing section 33; one end of the bending section 311 connected to the sensing section 33 extends upward with an inclined arm, and the upper end of the inclined arm is bent; the arc groove 15 holds the bending section 311.

[0080] The curvature of the arc-shaped groove 15 matches the curvature of the inclined arm of the bent section 311. Simultaneously, the arc-shaped groove 15 can be filled with adhesive, forming a sealed structure between the connecting section 31, the arc-shaped groove 15, and the electrode pressure plate 2, further improving the airtightness between the support structure 1, the electrode pressure plate 2, and the connecting section 31. The arc-shaped groove 15 also serves to fix the bent section 311, making the assembly of the bioelectrode 3 smoother.

[0081] Please refer to Figures 1-12. Figure 11 shows a highly sealed invasive bio-information monitoring device, including an upper shell 101, a bottom shell 102, and a biosensor 103. The upper shell 101 and the bottom shell 102 are connected by threads. The biosensor 103 includes a highly sealed invasive biosensing component 01 as disclosed in the above embodiments.

[0082] The biosensor 103 is sealed within the upper shell 101 and the bottom shell 102. A second sealing gasket 1011 is provided at the lower part of the upper shell 101. The second sealing gasket 1011 is pressed against the lower part of the upper shell 101 and the upper inner side of the bottom shell 102, so that a sealed space is formed between the upper shell 101 and the bottom shell 102, which improves the sealing performance of the inside of the high-sealing invasive bio-information monitoring device, thereby further improving the sealing performance of the high-sealing invasive bio-information monitoring device 02.

[0083] In this embodiment, a support base 104 is also included;

[0084] The bottom shell 102 is provided with a through hole, and the support base 104 passes through the through hole and enters the interior of the bottom shell 102;

[0085] The upper part of the support base 104 is snapped into the lower part of the sealing sleeve 5, and the fixing piece 1041 of the support base 104 is fixedly installed on the bottom of the outer side of the bottom shell 102.

[0086] A third sealing groove 1021 is provided at the bottom of the outer shell 102, and a third sealing gasket 1022 is provided on the upper part of the fixing plate 1041. The third sealing gasket 1022 is pressed into the third sealing groove 1021, so that a sealed space is formed between the upper shell 101, the bottom shell 102 and the fixing plate 1041, which improves the sealing performance of the inside of the high-sealing invasive bio-information monitoring device, thereby further improving the sealing performance of the high-sealing invasive bio-information monitoring device 02.

[0087] In this embodiment, an annular drying block is also included. The annular drying block is disposed at the bottom inside the bottom shell 102, and the upper part of the support base 104 passes through the annular drying block. Several cantilever hook beams extend upward from the bottom inside the bottom shell 102, and the cantilever hook beams hook the annular drying block. The annular drying block is fixed inside the bottom shell 102 and surrounds the support base 104. It can absorb water vapor, liquid, etc. that enter the high-sealing invasive bio-information monitoring device 02, thereby further improving the sealing performance of the high-sealing invasive bio-information monitoring device 02.

[0088] The bioelectrode 3, support structure 1, electrode pressure plate 2, and sealing sleeve 4 are assembled as a single unit during manufacturing to form a high-sealing invasive biosensor component 01. After uniform sterilization, it can maintain high sealing performance. When other components such as circuit boards and batteries are assembled later, there is no need to consider the problem of over-assembly or under-assembly of the bioelectrode 3 and circuit board / or the transmitter carrying the circuit board, which improves the stability of the high-sealing invasive biosensor component 01 before and after implantation in the human body.

[0089] The highly sealed invasive bioinformatics monitoring device 02 forms a closed space inside, maintaining a sealed and sterile state during manufacturing, transportation, and shelf placement, thus improving product stability and safety. For mass production, only the highly sealed invasive biosensor component 01 needs to be manufactured and assembled in a sterile environment; other components can be manufactured and assembled in a normal production environment. This reduces the environmental requirements for manufacturing and improves production efficiency during sterilization procedures.

[0090] During factory assembly, the upper shell 101, the bottom shell 102, and the support base 104 form a sealed space. When the product is not in use, the sealed invasive biosensor component 01 is stored in the sealed space. During pre-implantation assembly, the upper shell 101 and the bottom shell 102 are separated to expose the bioelectrode 3 and the guide needle 4 to be implanted. The bioelectrode 3 and the guide needle 4 are only exposed to the air when the upper shell 101 and the bottom shell 102 are separated, which is a very short time. This reduces the risk of contamination of the bioelectrode 3 and the guide needle 4, improves the safety of the bioelectrode 3 and the guide needle 4 when implanted in the human body, and further improves the stability and safety of the product.
