The electronic components 4 are directly arranged on the upper surface of the flexible circuit board 1 layer, and a buffer double-sided tape 03 is arranged between the electronic components 4. The height of the buffer double-sided tape 03 is higher than the electronic components 4. When another double-sided tape is pressed on the electronic components 4 and the flexible circuit board 1 layer, the buffer double-sided tape 03 is first deformed by the external pressure, and the electronic components 4 and the flexible circuit 1 layer are then subjected to the external pressure. The buffer double-sided tape 03 provides a reaction force for the electronic components 4 and the flexible circuit 1 layer to buffer the external pressure, thereby reducing the risk of damage to the electronic components 4 and the flexible circuit 1 layer during assembly and facilitating assembly. At the same time, the assembly of the electronic components 4 and the buffer double-sided tape 03 does not interfere with each other, making the internal structure of the entire bio-information monitoring device more compact, further reducing the thickness of the product, and at the same time helping to protect the electronic components 4 and reduce the thickness of the product.

[0072] At the same time, the axial projection of the buffer double-sided tape 03 is located between the flexible battery 3 and the electronic components 4, so that the buffer double-sided tape 03 can not only fix and buffer the flexible circuit board 1 and the electronic components 4, but also further fix the subsequent guide needles and other fixing tapes that pass through the flexible circuit board 1, thereby facilitating the subsequent assembly of the guide needles and other fixing tape components.

[0073] Please refer to Figures 1 to 11 In this embodiment, the flexible circuit board 1, the flexible battery 3 and the bioelectrode 2 are respectively provided with a first guide needle through hole 13, a second guide needle through hole 32 and a third guide needle through hole 22 in the middle thereof;

[0074] The diameter of the first guide pin through hole 13 of the flexible battery 3 is greater than or equal to the diameter of the second guide pin through hole 32 , and the diameter of the second guide pin through hole 32 of the flexible battery 3 is greater than or equal to the diameter of the third guide pin through hole 22 of the flexible battery 3 ;

[0075] The central axes of the first guide pin through hole 13 , the second guide pin through hole 32 , and the third guide pin through hole 22 of the flexible battery 3 coincide with each other.

[0076] In this embodiment, specifically, the first guide needle through hole 13, the second guide needle through hole 32 and the third guide needle through hole 22 are respectively arranged at the middle part, preferably the center position of the flexible circuit board 1, the flexible battery 3 and the biological electrode 2, and the first guide needle through hole 13, the second guide needle through hole 32 and the third guide needle through hole 22 share the central axis. During assembly, the guide needle assembly passes through the first guide needle through hole 13, the second guide needle through hole 32 and the third guide needle through hole 22 respectively, so that the gap between the guide needle assembly and the first guide needle through hole 13, the second guide needle through hole 32 and the third guide needle through hole 22 is minimized, thereby improving the sealing performance of the overall product, further improving the assembly convenience and reliability, and reducing the alignment requirement.

[0077] In this embodiment, specifically, the diameter of the first guide needle through hole 13 is equal to the diameter of the second guide needle through hole 32, and the diameter of the second guide needle through hole 32 of the flexible battery 3 is greater than or equal to the diameter of the third guide needle through hole 22 of the flexible battery 3. When the guide needle passes through the third guide needle through hole 22, the needle seat part of the guide needle is located on the upper surface of the biological electrode 2, the needle body part of the guide needle passes through the third guide needle through hole 22 of the biological electrode 2 and enters the electrode protection cover, and the electrode protection cover is pressed on the bottom surface of the biological electrode 2, so that the needle seat part of the guide needle and the electrode protection cover can extrude part of the biological electrode 2 outside the periphery of the third guide needle through hole 22 of the biological electrode 2, and the inner side wall of the third guide needle through hole 22 protrudes from the sensing segment of the biological electrode 2. The sensing segment is located in the closed space formed by the needle seat part of the guide needle, the biological electrode 2 and the electrode protection cover, thereby reducing the pollution of the sensing segment by external water vapor, bacteria, dust and other substances, and ensuring the reliability of the biological electrode 2 before implantation into the human body. At the same time, the diameter of the third guide needle through hole 22 is smaller than that of the first guide needle through hole 13 and the second guide needle through hole 32, so that the guide needle seat part of the guide needle can be clamped on the biological electrode 2 around the third guide needle through hole 22 and will not pass through the third guide needle through hole 22, thereby facilitating the positioning and assembly of the guide needle and reducing the alignment requirement.

[0078] Please refer to Figures 1 to 11 In this embodiment, the buffer double-sided adhesive tape 03 is provided with a first fixing through hole 031, and the size, shape and position of the first fixing through hole 031 of the flexible battery 3 correspond to those of the first guide needle through hole 13.

[0080] The second double-sided adhesive tape 02 is provided with a third fixing through hole 021, and the size, shape and position of the third fixing through hole 021 of the flexible battery 3 correspond to those of the third guide needle through hole 22.

[0081] In this embodiment, specifically, the first fixing through hole 031 of the flexible battery 3 is set to correspond to the size, shape and position of the first guide pin through hole 13; the second fixing through hole 011 of the flexible battery 3 is set to correspond to the size, shape and position of the second guide pin through hole 32; the third fixing through hole 021 of the flexible battery 3 is set to correspond to the size, shape and position of the third guide pin through hole 22, so that when the guide needle passes through the first guide pin through hole 13, the second guide pin through hole 32 and the third guide pin through hole 22, the first fixing through hole 031, the second fixing through hole 011 and the third fixing through hole 021 can guide the position where the guide needle passes through, and at the same time, the guide needle can be further fixed by the adhesive property, further improving the convenience of assembly and reducing the requirements for alignment.
