Abstract
Description
Technical Field
[0001] The present invention relates to the field of biological information monitoring, and particularly to an ultra-thin biological information monitoring device. Background Art
[0002] For the diabetic population, traditional fingertip blood glucose meters have the disadvantages of being invasive, having limited information, being unable to reflect blood glucose fluctuations and give early warnings, and can no longer meet the needs of some people. In particular, it is of great significance to type 1 diabetic patients who require real-time transmission of blood glucose fluctuations and type 2 diabetic patients who need intensive insulin treatment. Due to the need for continuous blood glucose monitoring, a guide needle in a biological information monitoring device needs to be implanted into the subcutaneous tissue of the human body, and measuring the blood glucose concentration between tissue fluids is a continuous monitoring method available in reality. Its single service life is one to two weeks, avoiding the pain brought by the process of continuous fingertip blood collection and venous blood collection.
[0003] At present, most of the biological information monitoring devices used to monitor blood glucose on the market can only increase the size and thickness of the products due to various technical conditions. For example, the size of the battery, the thickness of the circuit board, the thickness of the plastic shell itself, and the electrode clamping connection method, etc., will all cause the products to look very thick and bulky. Not only is the product not beautiful to wear and uncomfortable to wear in life, but also because the product is too tall, it is easily scratched off by objects such as clothes and door frames, causing losses to consumers.

[0052] To achieve the above object, please refer to Figures 1 to 15 , attached Figure 1 is an exploded structural schematic diagram of the ultra-thin biological information monitoring device of the present invention. Specifically, an ultra-thin biological information monitoring device includes: a flexible circuit board 1, a biological electrode 2, and a flexible battery 3;
[0053] An electronic component 4 is provided on the top surface of the flexible circuit board 1. The flexible battery 3 is attached to the top of the flexible circuit board 1, and the electronic component 4 is 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 biological electrode 2. The first power supply pad group of the flexible circuit board 1 is electrically connected to the flexible battery 3, and the second power supply pad group of the biological electrode 2 is electrically connected to the flexible circuit board 1.
[0055] In the technical solution provided by the present invention, the layer of the flexible circuit board 1 containing electronic components is 0.7 mm thick, the layer of the annular flexible battery 3 is 0.5 mm thick, the layer of the biological electrode 2 is 0.15 mm thick, the adhesive between the layer of the flexible circuit board 1 and the layer of the biological electrode 2 is 0.1 mm thick. On one side of the outside of the layer of the biological electrode 2 and the layer of the annular flexible battery 3, there are double-sided adhesives with a thickness of 0.1 mm, which are the first double-sided adhesive 6 and the second double-sided adhesive 7 respectively. After the ultra-thin biological information monitoring device is attached to the human skin surface through the first double-sided adhesive 6, a reinforced single-sided adhesive with a thickness of 0.1 mm is attached to the top of the second double-sided adhesive. The overall thickness of the device does not exceed 2 mm, reducing the overall thickness of the product.
[0056] The protective cover passes through the annular flexible battery 3, saving the height space of the battery. The present invention not only helps to protect the electronic component 4, but also further reduces the product volume, making the thickness of its key part only about 2 mm, greatly improving the user experience.
[0057] An electronic component 4 is provided on the top surface of the flexible circuit board 1. The electronic component 4 adopts miniaturized packaging, reducing the thickness and increasing the flexibility, while being convenient for packaging; there is a hollow in the middle part of the flexible circuit board 1 for passing through the biological electrode 2 and / or the guiding needle; multiple conductive contacts are provided on the top surface and / or the bottom surface of the flexible circuit board 1 for electrically connecting with the conductive contacts of the flexible battery 3 and the biological electrode 2. The electrical connection methods include, but are not limited to, conductive adhesive curing, conductive double-sided adhesive pasting, solder welding, riveting, etc.
[0058] The bioelectrode 2 and the flexible circuit board 1 are assembled by a double-sided adhesive tape; multiple conductive contacts are provided on the top surface and / or the bottom surface of the bioelectrode 2, including electrode lead-out contacts or other transfer contacts; and are 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 tape pasting, solder welding, riveting, etc.; the back surface of the bioelectrode 2 is fixedly bonded to the double-sided adhesive tape or other structures;

[0060] Please refer to Figures 1 to 14 , in this embodiment, the first power supply 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 provided on the top surface of the flexible circuit board 1, and the third conductive contact 113 and the fourth conductive contact 114 are provided 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 adhesive, and the second conductive contact 112 is electrically connected to the fourth conductive contact 114 through a 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 setting is more conducive to the reliability and ease of use of contact, 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 devices, reducing the thickness of the bioelectrode 2, and at the same time, a corresponding model of bioinformation monitoring device such as a continuous blood glucose monitor can be quickly manufactured, meeting the requirements of rapid production and rapid replacement of the biosensor component.
[0062] Please refer to Figures 1 to 14 , in this embodiment, a fixing adhesive tape 5 is provided between the flexible battery 3 and the flexible circuit board 1. The flexible battery 3 is attached to the fixing adhesive tape 5, and the flexible circuit board 1 is attached to the bottom of the fixing adhesive tape 5. The fixing adhesive tape 5 is provided with a composite special-shaped structure; the fixing adhesive tape 5 is provided with an avoidance through hole 52 for avoiding the electronic component 4;
[0063] The flexible battery 3 is attached to the fixing adhesive tape 5, the flexible circuit board 1 is attached to the bottom of the fixing adhesive tape 5, and the electronic component 4 is embedded in the avoidance through hole 52.
[0064] The fixing adhesive sticker 5 is also provided with at least two conductive filling through holes 51. In this embodiment, two conductive filling through holes 51 are provided, and more than two conductive filling through holes 51 can also be provided, such as four. The alignment requirements between the flexible battery 3 and the flexible circuit board 1 can be reduced through multiple conductive filling through holes 51.
[0065] A conductive material is arranged in the conductive filling through hole 51. The conductive material includes one or more of conductive glue, conductive silica gel particles, conductive double-sided tape, and welding materials. In this embodiment, the conductive material includes conductive silica gel particles and can also include conductive double-sided tape.
[0066] The conductive material in the conductive filling through hole 51 is used for the first conductive contact 111 and the third conductive contact 113 to form an electrical connection through the conductive material in one conductive filling through hole 51, and the second conductive contact 112 and the fourth conductive contact 114 to form an electrical connection through the conductive material in the other conductive filling through hole 51.
[0067] In this embodiment, the avoidance through holes 52 are arranged diagonally, the conductive filling through holes 51 are arranged diagonally, and the avoidance through holes 52 are located on both sides of the connection line of the conductive filling through holes 51.
[0068] The electronic components 4 can be distributed on both sides of the fixing adhesive sticker 5. The electronic components 4, such as Bluetooth chips, electrochemical chips, large-capacitance inductors, crystal oscillators, etc. of the CGM transmitter hardware, are relatively large in size and height, with a size exceeding and a height exceeding 0.4 mm, or having more pins, etc., are arranged in the accommodation grooves under the annular flexible battery 3, reducing the installation height of the electronic components 4. The arrangement of the accommodation grooves enables the device to accommodate larger-sized electronic components 4. The electronic components 4 are located on both sides of the connection line between 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, and the electronic components 4 are arranged diagonally. The diagonal arrangement of the conductive filling through holes 51 makes the assembly of the electronic components 4 and the fixing adhesive sticker 5 accommodating the first power supply pad group non-interfering, making the internal structure of the entire biological information monitoring device more compact, further reducing the product thickness, and at the same time being beneficial to protecting the electronic components 4 and reducing the product thickness.
[0069] In this embodiment, an avoidance groove 31 is arranged at the middle bottom of the flexible battery 3. The third conductive contact 113 and the fourth conductive contact 114 are arranged at the bottom of the avoidance groove 31, and the fixing adhesive sticker 5 is arranged at the avoidance groove 31.
[0070] Due to the provision of the avoidance groove 31, there is an avoidance space for accommodating the fixing adhesive 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 adhesive sticker 5 is disposed in the avoidance groove 31. Firstly, it can fix the flexible battery 3 and the flexible circuit board 1 through adhesion. Secondly, since the third conductive contact 113 and the fourth conductive contact 114 are disposed at the bottom of the avoidance groove 31 and the conductive contacts are arranged in a flat shape, the first power pad groups cannot form electrical connection through direct pressing. Therefore, the flexible circuit board 1 and the flexible battery 3 are electrically connected through the conductive adhesive in the conductive filling through hole 51. The avoidance groove 31 can accommodate the fixing adhesive sticker 5, reducing the thickness after the flexible battery 3 and the flexible circuit board 1 are attached, and making the thickness of the overall device smaller.
[0071] A sealing portion 32 is provided on the outer periphery of the flexible battery 3. 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 disposed in the receiving groove, further reducing the thickness of the device.
[0072] In this embodiment, a first double-sided adhesive sticker 6 is attached to the bottom of the biological electrode 2. The side of the first double-sided adhesive sticker 6 close to the biological electrode 2 is attached to the lower part of the sealing portion 32. A second double-sided adhesive sticker 7 is attached to the top surface of the flexible battery 3. The side of the second double-sided adhesive sticker 7 close to the flexible battery 3 is attached to the first double-sided adhesive sticker 6. The flexible circuit board 1, the biological electrode 2 and the electronic component 4 are disposed in the space surrounded by the first double-sided adhesive sticker 6 and the second double-sided adhesive sticker 7.
[0073] Specifically, the lower part of the sealing portion 32 is attached to the first double-sided adhesive sticker 6, and the second double-sided adhesive sticker 7 is attached to the first double-sided adhesive sticker 6 and the flexible battery 3 respectively, thereby fixing the flexible battery 3, making the flexible battery 3 not easy to shift, and at the same time reducing the thickness of the device.
[0074] The part of the flexible battery 3 between the sealing portion 32 and the avoidance groove 31 forms an annular boss relative to the two. Electric power is stored in the annular boss. The thickness of the annular boss is relatively thicker than the thickness of the avoidance groove 31, making the device have a stronger battery life. The avoidance groove 31 and the sealing portion 32 are thinner, and the lower thickness is more conducive to bending, mainly for connecting with the first double-sided adhesive sticker 6.
[0075] In this embodiment, a single-sided reinforcement adhesive sticker is also attached to the second double-sided adhesive sticker 7. The area of the single-sided reinforcement adhesive sticker is larger than the areas of the first double-sided adhesive sticker 6 and the second double-sided adhesive sticker 7, so that the peripheries of the single-sided reinforcement adhesive sticker respectively expose the peripheries of the first double-sided adhesive sticker 6 and the second double-sided adhesive sticker 7. The exposed parts of the single-sided reinforcement adhesive sticker and the lower surface of the first double-sided adhesive sticker 6 are attached to the human skin, thereby further fixing the device on the human skin and making it not easy to shift.
[0076] Please refer to Figures 1 to 14, in this embodiment, the second power supply pad group 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, the sixth conductive contact 116, and the seventh conductive contact 117 are disposed on the bottom surface of the flexible circuit board 1, and the counter electrode contact 211, the reference electrode contact 212, and the working electrode contact 213 are disposed on the top surface of the biological electrode 2. The counter electrode contact 211 is electrically connected to the fifth conductive contact 115 through a conductive adhesive, the reference electrode contact 212 is electrically connected to the sixth conductive contact 116 through a conductive adhesive, and the working electrode contact 213 is electrically connected to the seventh conductive contact 117 through a conductive adhesive. The flexible battery 3 and the flexible circuit board 1, and the biological electrode 2 and the flexible circuit board 1 are respectively electrically connected through a plurality of conductive contacts and conductive adhesives, making the internal structure of the entire biological information monitoring device more compact and further reducing the product thickness.
[0077] Please refer to Figures 1 to 14 , in this embodiment, the biological electrode 2 is provided with a first through hole 22, and the sensing section 23 of the biological electrode 2 extends from the side wall of the first through hole 22, and the sensing section 23 can be bent downward;
[0078] Before bending, the sensing section 23 extends straight in the first through hole 22. After bending, the sensing section 23 leaks out from the bottom of the biological electrode 2. The biological electrode 2 is integrally provided, and only the sensing section 23 is bent downward, reducing the overall thickness of the biological electrode 2, facilitating production and further reducing the 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 penetrates up and down. 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, facilitating the subsequent connection of the guiding needle and the protective cover to 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 guiding needle to pass through, while the single-sided reinforcement adhesive tape does not have assembly through holes. After the guiding needle is pulled out, it is used to isolate external moisture from entering the assembly through holes, reducing the risk of bacteria breeding at the wound formed by the external moisture and the guiding needle.
[0081] In another embodiment, please refer to the appendix Figures 1 - 15 , appendix Figure 14 This application provides an ultra-thin biological information monitoring device, including the ultra-thin biological information monitoring device proposed in the above embodiment, and further including a guiding needle and a protective cover. The guiding needle sequentially passes through the first double-sided adhesive tape 6, the flexible battery 3, the fixing adhesive tape 5, the flexible circuit board 1, the biological electrode 2, and the second double-sided adhesive tape 7 and enters the protective cover;
