[0002] For people with diabetes, traditional finger-prick blood glucose meters have drawbacks such as being invasive, providing limited information, and failing to reflect blood glucose fluctuations or provide early warnings. They no longer meet the needs of some individuals, especially type 1 diabetes patients who require real-time transmission of blood glucose fluctuations and type 2 diabetes patients requiring intensive insulin therapy. Due to the need for continuous blood glucose monitoring, a bio-information monitoring device is needed, where a guide needle is implanted under the skin to measure blood glucose concentration in the tissue fluid.

Detailed Implementation

[0048] To facilitate understanding of this disclosure, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only. In the description of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or implying the number of indicated technical features. Thus, unless otherwise stated, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more. The term "comprising" and any variations thereof mean non-exclusive inclusion, where one or more other features, integers, steps, operations, units, components, and / or combinations thereof may be present or added.

[0049] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium, or a connection within two components. All technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0050] Furthermore, the technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0051] Currently, most bio-information monitoring devices for blood glucose monitoring on the market are limited by various technical conditions, resulting in large product sizes and thicknesses. For example, the size of the battery, the thickness of the circuit board, the thickness of the plastic casing, and the electrode clamping connection method all contribute to the product's bulky and cumbersome appearance. This not only makes the product less aesthetically pleasing and uncomfortable to wear, but also makes it easy for it to be knocked off by clothing, door frames, or other objects due to its height, causing losses to consumers.

[0052] To achieve the above objectives, please refer to Figures 1 to 15. Figure 1 is a schematic diagram of the exploded structure of the ultra-thin bio-information monitoring device of this disclosure. Specifically, an ultra-thin bio-information monitoring device includes: a flexible circuit board 1, a bioelectrode 2, and a flexible battery 3.

[0053] Electronic components 4 are disposed on the top surface of the flexible circuit board 1, and the flexible battery 3 is attached to the top of the flexible circuit board 1. The electronic components 4 are located between the flexible battery 3 and the flexible circuit board 1.

[0054] The flexible circuit board 1 is attached to the top of the bioelectrode 2. The first power pad group of the flexible circuit board 1 is electrically connected to the flexible battery 3, and the second power pad group of the bioelectrode 2 is electrically connected to the flexible circuit board 1.

[0055] In the technical solution provided in this disclosure, the flexible circuit board layer 1 containing electronic components is 0.7mm thick, the annular flexible battery layer 3 is 0.5mm thick, the bioelectrode layer 2 is 0.15mm thick, the adhesive between the flexible circuit board layer 1 and the bioelectrode layer 2 is 0.1mm thick, and the outer side of the bioelectrode layer 2 and the annular flexible battery layer 3 are both provided with 0.1mm thick double-sided adhesive tapes, namely the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7. After the ultra-thin bio-information monitoring device is attached to the surface of human skin through the first double-sided adhesive tape 6, a reinforcing single-sided adhesive tape of 0.1mm thick is attached to the top of the second double-sided adhesive tape. The overall thickness of the device does not exceed 2mm, thus reducing the overall product thickness.

[0056] The protective cover passes through the annular flexible battery 3, saving space in the battery's height. This disclosure not only helps protect the electronic components 4, but also further reduces the product size, making the thickness of its key parts only about 2mm, greatly improving the user experience.

[0057] The top surface of the flexible circuit board 1 is provided with electronic components 4. The electronic components 4 are miniaturized and packaged to reduce thickness, increase flexibility, and facilitate packaging. The middle part of the flexible circuit board 1 has a cutout for the bioelectrode 2 and / or guide pin to pass through. The top and / or bottom surfaces of the flexible circuit board 1 are provided with multiple conductive contacts for electrical connection with the conductive contacts of the flexible battery 3 and the bioelectrode 2. The electrical connection methods include, but are not limited to, conductive adhesive curing, conductive double-sided adhesive bonding, solder welding, riveting, etc.

[0058] The bioelectrode 2 is assembled with the flexible circuit board 1 using double-sided adhesive tape; the top and / or bottom surfaces of the bioelectrode 2 are provided with multiple conductive contacts, including electrode lead-out contacts or other transfer contacts; it is electrically connected to the conductive contacts of the flexible circuit board 1 and / or the flexible battery 3, and the electrical connection methods include conductive adhesive curing, conductive double-sided adhesive bonding, solder welding, riveting, etc.; the back of the bioelectrode 2 is fixedly bonded to the double-sided adhesive tape or other structures.

[0059] The flexible battery 3 has conductive contact tabs on its top or back surface for leading out the positive and negative terminals of the battery. These conductive contacts are electrically connected to the conductive contacts of the flexible circuit board 1 according to the system design. The electrical connection methods include conductive adhesive curing, conductive double-sided adhesive bonding, solder welding, riveting, etc. The flexible battery 3 has a through hole in the middle for the guide pin and / or protective cover and / or bioelectrode 2 to pass through.

[0060] Referring to Figures 1 to 14, in this embodiment, the first power pad group includes a first conductive contact 111, a second conductive contact 112, a third conductive contact 113, and a fourth conductive contact 114. The first conductive contact 111 and the second conductive contact 112 are disposed on the top surface of the flexible circuit board 1, and the third conductive contact 113 and the fourth conductive contact 114 are disposed on the bottom surface of the flexible battery 3. The first conductive contact 111 is electrically connected to the third conductive contact 113 through conductive adhesive, and the second conductive contact 112 is electrically connected to the fourth conductive contact 114 through conductive adhesive.

[0061] Specifically, the first conductive contact 111, the second conductive contact 112, the third conductive contact 113, and the fourth conductive contact 114 are all flat planar contacts. The planar design is more conducive to the reliability and ease of use of the contact, and at the same time, it helps to reduce the thickness of the product. In addition, the shape, size, and spacing of the contacts can be flexibly adjusted according to external components and equipment, which reduces the thickness of the bioelectrode 2 and enables the rapid manufacture of corresponding models of bioinformation monitoring devices, such as continuous glucose meters, meeting the requirements of rapid production and rapid replacement of biosensor components.

[0062] Referring to Figures 1 to 14, in this embodiment, a fixing adhesive 5 is provided between the flexible battery 3 and the flexible circuit board 1. The flexible battery 3 is attached to the fixing adhesive 5, and the flexible circuit board 1 is attached to the bottom of the fixing adhesive 5. The fixing adhesive 5 has a composite irregular structure; the fixing adhesive 5 is provided with a clearance through hole 52, which is used to avoid electronic components 4.

[0063] The flexible battery 3 is attached to the fixing adhesive 5, the flexible circuit board 1 is attached to the bottom of the fixing adhesive 5, and the electronic component 4 is embedded in the clearance through hole 52.

[0064] The fixing adhesive 5 is also provided with at least two conductive filling through holes 51. In this embodiment, two conductive filling through holes 51 are provided, but more than two conductive filling through holes 51, such as four, can also be provided. Multiple conductive filling through holes 51 can reduce the alignment requirements between the flexible battery 3 and the flexible circuit board 1.

[0065] Conductive material is disposed within the conductive filling through-hole 51. The conductive material includes one or more of conductive adhesive, conductive silicone particles, conductive double-sided adhesive, and welding material. In this embodiment, the conductive material includes conductive silicone particles, and may also include conductive double-sided adhesive.

[0066] The conductive material in the conductive filling through-hole 51 is used to form an electrical connection between the first conductive contact 111 and the third conductive contact 113 through the conductive material in the conductive filling through-hole 51, and to form an electrical connection between the second conductive contact 112 and the fourth conductive contact 114 through the conductive material in the other conductive filling through-hole 51.

[0067] In this embodiment, the avoidance through holes 52 are diagonally arranged, and the conductive filling through holes 51 are diagonally arranged, with the avoidance through holes 52 located on both sides of the line connecting the conductive filling through holes 51.

[0068] Electronic components 4 can be distributed on both sides of the fixing adhesive 5. These components, such as Bluetooth chips, electrochemical chips, large capacitors and inductors, crystal oscillators, etc., of the CGM transmitter hardware, are relatively large and tall, exceeding 0.8*0.8mm in size and 0.4mm in height, or have many pins. They are housed in the receiving groove under the annular flexible battery 3, reducing the installation height of the electronic components 4. The receiving groove allows the device to accommodate larger electronic components 4. The electronic components 4 are located on both sides of the line connecting the third conductive contact 113 and the fourth conductive contact 114, which are diagonally positioned. The conductive filling through-holes 51 are also diagonally positioned, ensuring that the assembly of the electronic components 4 and the fixing adhesive 5 accommodating the first power pad group does not interfere with each other. This makes the internal structure of the entire bio-information monitoring device more compact, further reducing the product thickness, and also helps protect the electronic components 4, further reducing the product thickness.

[0069] In this embodiment, a clearance groove 31 is provided at the bottom of the middle part of the flexible battery 3, the third conductive contact 113 and the fourth conductive contact 114 are provided at the bottom of the clearance groove 31, and the fixing adhesive 5 is provided at the clearance groove 31.

[0070] Due to the arrangement of the clearance groove 31, there is clearance space between the bottom center of the flexible battery 3 and the flexible circuit board 1 for accommodating the fixing adhesive 5 and / or electronic components 4. The fixing adhesive 5 is arranged in the clearance groove 31. Firstly, it can fix the flexible battery 3 and the flexible circuit board 1 with adhesiveness. Secondly, because the third conductive contact 113 and the fourth conductive contact 114 are arranged at the bottom of the clearance groove 31 and the conductive contacts are set in a flat shape, the first power pad group cannot form an electrical connection through direct pressure contact. Therefore, the conductive adhesive in the conductive filling through hole 51 enables the flexible circuit board 1 and the flexible battery 3 to form an electrical connection. The clearance groove 31 can accommodate the fixing adhesive 5, which reduces the thickness of the flexible battery 3 and the flexible circuit board 1 after bonding, and makes the overall thickness of the device smaller.

[0071] The flexible battery 3 has a sealing portion 32 on its outer periphery. The sealing portion 32 is bent downwards, so that the bottom of the flexible battery 3 forms a receiving groove. The electronic component 4 is located in the receiving groove, which further reduces the thickness of the device.

[0072] In this embodiment, a first double-sided adhesive tape 6 is attached to the bottom of the bioelectrode 2, and the side of the first double-sided adhesive tape 6 near the bioelectrode 2 is attached to the bottom of the sealing part 32. A second double-sided adhesive tape 7 is attached to the top surface of the flexible battery 3, and the side of the second double-sided adhesive tape 7 near the flexible battery 3 is attached to the first double-sided adhesive tape 6. The flexible circuit board 1, the bioelectrode 2 and the electronic components 4 are disposed in the space enclosed by the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7.

[0073] Specifically, the lower part of the sealing part 32 is attached to the first double-sided adhesive tape 6, and the second double-sided adhesive tape 7 is attached to the first double-sided adhesive tape 6 and the flexible battery 3 respectively, thereby fixing the flexible battery 3, making the flexible battery 3 less prone to displacement, and reducing the thickness of the device.

[0074] The flexible battery 3 portion between the sealing part 32 and the clearance groove 31 forms an annular boss relative to the two. The annular boss stores electrical energy. The thickness of the annular boss is relatively thicker than that of the clearance groove 31, which makes the device have a stronger endurance. The clearance groove 31 and the sealing part 32 are thinner and have a lower thickness, which is more conducive to bending. They are mainly used to connect with the first double-sided adhesive 6.

[0075] In this embodiment, a single-sided reinforcing adhesive is also attached to the second double-sided adhesive tape 7. The area of ​​the single-sided reinforcing adhesive tape is larger than that of the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7, so that the periphery of the single-sided reinforcing adhesive tape protrudes from the periphery of the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7, respectively. The protruding part of the single-sided reinforcing adhesive tape and the lower surface of the first double-sided adhesive tape 6 are attached to the human skin, thereby further fixing the device to the human skin and making it less prone to displacement.

[0076] Referring to Figures 1 to 14, in this embodiment, the second power pad assembly includes a fifth conductive contact 115, a sixth conductive contact 116, a seventh conductive contact 117, a counter electrode contact 211, a reference electrode contact 212, and a working electrode contact 213. The fifth conductive contact 115, sixth conductive contact 116, and seventh conductive contact 117 are located on the bottom surface of the flexible circuit board 1. The counter electrode contact 211, reference electrode contact 212, and working electrode contact 213 are located on the top surface of the bioelectrode 2. The counter electrode contact 211 is electrically connected to the fifth conductive contact 115 via conductive adhesive, the reference electrode contact 212 is electrically connected to the sixth conductive contact 116 via conductive adhesive, and the working electrode contact 213 is electrically connected to the seventh conductive contact 117 via conductive adhesive. The flexible battery 3 and the flexible circuit board 1, as well as the bioelectrode 2 and the flexible circuit board 1, are electrically connected via several conductive contacts and conductive adhesive, making the internal structure of the entire bio-information monitoring device more compact and further reducing the product thickness.

[0077] Please refer to Figures 1 to 14. In this embodiment, the bioelectrode 2 is provided with a first through hole 22, and the sensing section 23 of the bioelectrode 2 extends out from the side wall of the first through hole 22. The sensing section 23 can be bent downward.

[0078] Before bending, the sensing segment 23 extends straight within the first through hole 22; after bending, the sensing segment 23 protrudes from the bottom of the bioelectrode 2. The bioelectrode 2 is integrally formed, with only the sensing segment 23 bent downwards, reducing the overall thickness of the bioelectrode 2, facilitating manufacturing, and further minimizing product thickness.

[0079] Please refer to Figures 1 to 14. In this embodiment, the flexible circuit board 1 is provided with a second through hole 12, and the flexible battery 3 is provided with a third through hole 33 that runs vertically through the device. The centers of the first through hole 22, the second through hole 12, and the third through hole 33 are located on the same longitudinal axis, which facilitates the subsequent connection of the guide pin and the protective cover with the device.

[0080] Both the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7 are provided with assembly through holes for the guide needle to pass through. The single-sided reinforcing adhesive is not provided with assembly through holes. It is used to isolate external moisture from entering the assembly through holes after the guide needle is pulled out, thereby reducing the risk of external moisture growing bacteria at the wound formed by the guide needle.

[0081] In another embodiment, please refer to Figures 1-15. Figure 14 shows an ultra-thin bio-information monitoring device proposed in this disclosure, which includes the ultra-thin bio-information monitoring device proposed in the above embodiment, and also includes a guide needle and a protective cover. The guide needle passes through the first double-sided adhesive 6, the flexible battery 3, the fixing adhesive 5, the flexible circuit board 1, the bioelectrode 2 and the second double-sided adhesive 7 in sequence and enters the protective cover.

[0082] When the factory assembly is completed, the protective cover and the guide pin are connected by threads, clamping the ultra-thin bio-information monitoring device between the protective cover and the guide pin seat;

[0083] Before implantation, unscrew the protective cover, and the guide needle protrudes from the bottom of the second double-sided adhesive tape 7. The guide needle is then partially implanted into the human skin using an external pushing device. The guide needle is then quickly removed, leaving the sensing segment 23 partially implanted in the human skin. Finally, a single-sided reinforcing adhesive tape is applied to the first double-sided adhesive tape 6, thus fixing the ultra-thin bio-information monitoring device to the human skin. The sensing segment 23 is not easily displaced and collects bio-signals from the human skin. The collected bio-signals are transmitted to the flexible circuit board 1 through the reference electrode contact 212, the working electrode contact 213, and the counter electrode contact 211.
