It can no longer meet the needs of some people, especially for type 1 diabetes patients who have real-time transmission requirements for blood sugar fluctuations and type 2 diabetes patients who need intensive insulin treatment. Due to the need for continuous blood sugar monitoring, the guide needle in the bioinformation monitoring device needs to be implanted into the subcutaneous tissue of the human body.

[0024] In the technical solution provided by the present invention, the flexible circuit board layer 1 containing electronic components is 0.7mm thick, the annular flexible battery layer 3 is 0.5mm thick, the bio-electrode layer 2 is 0.15mm thick, the adhesive tape between the flexible circuit board layer 1 and the bio-electrode layer 2 is 0.1mm thick, and the outer sides of the bio-electrode 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 reinforced single-sided adhesive tape 0.1mm thick is attached to the top of the second double-sided adhesive tape. The thickness of the overall device does not exceed 2mm, thereby reducing the thickness of the overall product.

[0025] The protective cover passes through the annular flexible battery 3 to save the height space of the battery. The present invention is not only conducive to protecting the electronic components 4, but also further reduces the volume of the product, so that the thickness of the key part is only about 2mm, which greatly improves the user experience.

[0026] An electronic component 4 is arranged on the top surface of the flexible circuit board 1. The electronic component 4 adopts a miniaturized package to reduce the thickness, increase the flexibility, and facilitate packaging. The middle part of the flexible circuit board 1 is hollowed out for passing the biological electrode 2 and / or the guide needle. A plurality of conductive contacts are arranged on the top surface and / or the bottom surface of the flexible circuit board 1 to electrically connect with the conductive contacts of the flexible battery 3 and the biological electrode 2. The electrical connection method includes but is not limited to conductive glue curing, conductive double-sided tape pasting, solder welding, riveting, etc.

[0027] The bioelectrode 2 is assembled with the flexible circuit board 1 by means of a double-sided adhesive tape; a plurality of conductive contacts are arranged on the top surface or / and the bottom surface of the bioelectrode 2, including electrode lead contacts or other transfer contacts; the bioelectrode 2 is electrically connected with the conductive contacts of the flexible circuit board 1 and / or the flexible battery 3, and the electrical connection method includes conductive adhesive curing, conductive double-sided adhesive pasting, solder welding, riveting, etc.; the back surface of the bioelectrode 2 is fixedly bonded with the double-sided adhesive tape or other structures; The top surface or back surface of the flexible battery 3 is provided with a conductive contact ear for leading out the positive and negative electrodes of the battery.

The electrical connection method includes conductive glue curing, conductive double-sided tape pasting, solder welding, riveting, etc.; the middle part of the flexible battery 3 is provided with a through hole for passing the guide needle and / or the protective cover and / or the biological electrode 2; Please refer to Figures 1 to 14In 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 arranged on the top surface of the flexible circuit board 1, and the third conductive contact 113 and the fourth conductive contact 114 are arranged on the bottom surface of the flexible battery 3. The first conductive contact 111 is electrically connected to the third conductive contact 113 through a conductive glue, and the second conductive contact 112 is electrically connected to the fourth conductive contact 114 through a conductive glue.

[0028] 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 setting is more conducive to contact reliability and ease of use, and is also conducive to reducing the thickness of the product; at the same time, the shape, size, and spacing of the contacts can be flexibly adjusted according to external components and equipment, thereby reducing the thickness of the bioelectrode 2. At the same time, corresponding models of biological information monitoring devices such as continuous blood glucose monitors can be quickly manufactured, meeting the requirements of rapid production and rapid replacement of biosensor components.

[0029] Please refer to Figures 1 to 14 In this embodiment, a fixing adhesive sticker 5 is provided between the flexible battery 3 and the flexible circuit board 1, the flexible battery 3 is attached to the fixing adhesive sticker 5, and the flexible circuit board 1 is attached to the bottom of the fixing adhesive sticker 5. The fixing adhesive sticker 5 is a composite special-shaped structure; the fixing adhesive sticker 5 is provided with an avoidance through hole 52, and the avoidance through hole 52 is used to avoid the electronic component 4; The flexible battery 3 is attached to the fixing adhesive sticker 5 , the flexible circuit board 1 is attached to the bottom of the fixing adhesive sticker 5 , and the electronic component 4 is embedded in the avoidance through hole 52 .

[0030] The fixing adhesive 5 is also provided with at least two conductive filling through holes 51. In this embodiment, the conductive filling through holes 51 are provided with two, and more than two conductive filling through holes 51, such as four, can be provided. The alignment requirements of the flexible battery 3 and the flexible circuit board 1 can be reduced by using multiple conductive filling through holes 51. Conductive material is disposed in the conductive filling through hole 51 , and the conductive material includes one or more of conductive glue, 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.

[0031] The conductive material in the conductive filled through-hole 51 is used for the first conductive contact 111 and the third conductive contact 113 to be electrically connected through the conductive material in one conductive filled through-hole 51 , and the second conductive contact 112 and the fourth conductive contact 114 to be electrically connected through the conductive material in another conductive filled through-hole 51 .

[0032] In this embodiment, the avoidance through holes 52 are arranged diagonally, and the conductive filling through holes 51 are arranged diagonally, and the avoidance through holes 52 are located on both sides of the line connecting the conductive filling through holes 51 .

[0033] The electronic components 4 can be distributed on both sides of the fixed adhesive 5. The electronic components 4, such as the Bluetooth chip, electrochemical chip, large capacitor inductor, crystal oscillator and other devices of the CGM transmitter hardware, are relatively large and high, and the size exceeds , the height exceeds 0.4mm, or there are many pins, etc., which are arranged in the receiving groove under the annular flexible battery 3, which reduces the installation height of the electronic component 4. The setting of the receiving groove enables the device to accommodate larger electronic components 4. The electronic component 4 is located on both sides of the connection line of the third conductive contact 113 and the fourth conductive contact 114. The third conductive contact 113 and the fourth conductive contact 114 are arranged diagonally, the electronic components 4 are arranged diagonally, and the conductive filled through holes 51 are arranged diagonally, so that the assembly of the electronic component 4 and the fixing adhesive sticker 5 accommodating the first power pad group does not interfere with each other, making the internal structure of the entire biological information monitoring device more compact, further reducing the product thickness, and at the same time, it is beneficial to protect the electronic component 4 and reduce the thickness of the product.

[0034] In this embodiment, a avoidance groove 31 is provided at the middle bottom of the flexible battery 3 , the third conductive contact 113 and the fourth conductive contact 114 are provided at the bottom of the avoidance groove 31 , and the fixing adhesive 5 is provided at the avoidance groove 31 .

[0035] Due to the setting of the avoidance groove 31, there is an avoidance space for accommodating the fixing sticker 5 and / or the electronic component 4 between the middle bottom of the flexible battery 3 and the flexible circuit board 1. The fixing sticker 5 is set in the avoidance groove 31. First, the flexible battery 3 and the flexible circuit board 1 can be fixed by viscosity. Second, since the third conductive contact 113 and the fourth conductive contact 114 are set at the bottom of the avoidance groove 31, the conductive contacts are set to a flat shape, so that the first power pad group cannot be electrically connected by direct pressure contact, so the flexible circuit board 1 and the flexible battery 3 are electrically connected through the conductive glue in the conductive filling through hole 51; the avoidance groove 31 can accommodate the fixing sticker 5, so that the thickness of the flexible battery 3 and the flexible circuit board 1 after bonding is reduced, so that the thickness of the overall device is reduced.

[0036] A sealing portion 32 is provided on the outer periphery of the flexible battery 3 , and the sealing portion 32 is bent downward so that a receiving groove is formed at the bottom of the flexible battery 3 . The electronic component 4 is arranged in the receiving groove, further reducing the thickness of the device.

[0037] In this embodiment, a first double-sided tape 6 is affixed to the bottom of the bioelectrode 2, and a side of the first double-sided tape 6 close to the bioelectrode 2 is affixed to the bottom of the sealing portion 32. A second double-sided tape 7 is affixed to the top surface of the flexible battery 3, and a side of the second double-sided tape 7 close to the flexible battery 3 is affixed to the first double-sided tape 6. The flexible circuit board 1, the bioelectrode 2 and the electronic component 4 are arranged in the space surrounded by the first double-sided tape 6 and the second double-sided tape 7.

[0038] Specifically, the lower part of the sealing portion 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 it difficult for the flexible battery 3 to shift, and reducing the thickness of the device.

[0039] The part of the flexible battery 3 between the sealing part 32 and the avoidance groove 31 forms an annular boss relative to the two, and electricity is stored in the annular boss. The thickness of the annular boss is thicker than the thickness of the avoidance groove 31, so that the device has a stronger endurance. The avoidance groove 31 and the sealing part 32 are thinner, and the lower thickness is more conducive to bending, and is mainly used to connect with the first double-sided adhesive tape 6.

[0040] In this embodiment, a single-sided reinforcing adhesive tape is also affixed to the second double-sided adhesive tape 7, and 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 leaks out of the periphery of the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7 respectively, and the leaked part of the single-sided reinforcing adhesive tape and the lower surface of the first double-sided adhesive tape 6 are affixed to the human skin, thereby further fixing the device on the human skin and preventing it from shifting easily.

[0041] Please refer to Figures 1 to 14 In this embodiment, the second power pad group includes the fifth conductive contact 115, the sixth conductive contact 116, the seventh conductive contact 117, the counter electrode contact 211, the reference electrode contact 212 and the working electrode contact 213. The fifth conductive contact 115, the sixth conductive contact 116 and the seventh conductive contact 117 are arranged on the bottom surface of the flexible circuit board 1, the counter electrode contact 211, the reference electrode contact 212 and the working electrode contact 213 are arranged on the top surface of the bio-electrode 2, the counter electrode contact 211 is electrically connected to the fifth conductive contact 115 through a conductive glue, the reference electrode contact 212 is electrically connected to the sixth conductive contact 116 through a conductive glue, and the working electrode contact 213 is electrically connected to the seventh conductive contact 117 through a conductive glue. The flexible battery 3 and the flexible circuit board 1, the bio-electrode 2 and the flexible circuit board 1 are electrically connected through a plurality of conductive contacts and conductive glue, respectively, so that the internal structure of the entire biological information monitoring device is more compact, and the product thickness is further reduced.

[0042] Please refer to Figures 1 to 14In this embodiment, the bio-electrode 2 is provided with a first through hole 22, and the sensing section 23 of the bio-electrode 2 extends from the side wall of the first through hole 22, and the sensing section 23 can be bent downward; Before bending, the sensing section 23 extends straight in the first through hole 22, and after bending, the sensing section 23 leaks out of the bottom of the bio-electrode 2. The bio-electrode 2 is integrally arranged, and only the sensing section 23 is bent downward, so that the overall thickness of the bio-electrode 2 is reduced, which is convenient for production and further reduces the product thickness.

[0043] 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 extending vertically therethrough. 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 needle and the protective cover to the device.

[0044] Both the first double-sided adhesive tape 6 and the second double-sided adhesive tape 7 are provided with assembly holes for the guide needle to pass through, while the single-sided reinforcing adhesive tape is not provided with an assembly hole, which is used to isolate external water vapor from entering the assembly hole after the guide needle is pulled out, thereby reducing the risk of external water vapor breeding bacteria at the wound formed by the guide needle.

[0045] In another embodiment, please refer to the attached Figure 1-Figure 15 , attached Fig.14 The present application proposes an ultra-thin biological information monitoring device, including the ultra-thin biological information monitoring device proposed in the above embodiment, and also including a guide needle and a protective cover, wherein the guide needle sequentially passes through the first double-sided adhesive sticker 6, the flexible battery 3, the fixed adhesive sticker 5, the flexible circuit board 1, the biological electrode 2, and the second double-sided adhesive sticker 7 to enter the protective cover; When the factory assembly is completed, the protective cover and the guide needle are connected by threads, and the ultra-thin biological information monitoring device is clamped between the protective cover and the guide needle seat of the guide needle; When used before implantation, unscrew the protective cover, and the guide needle leaks out of the bottom of the second double-sided adhesive tape 7. The guide needle is half-implanted into the human skin through an external propulsion device, and the guide needle is quickly withdrawn, leaving the sensing segment 23 in the human skin, that is, half-implanted into the human skin. Finally, a single-sided reinforcement adhesive is pasted on the first double-sided adhesive tape 6, so that the ultra-thin biological information monitoring device is fixed on the human skin, the sensing segment 23 is not easy to shift, and collects biological signals in the human skin. The collected biological 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.
