Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram electrode patch technology, and in particular to a disposable flexible electrocardiogram electrode patch. Background Technology

[0002] In existing technologies, poor contact between the electrodes and the skin can easily lead to motion artifacts. During patient activity, due to insufficient fit or flexibility of traditional electrode patches, slight displacement may occur between the electrodes and the skin, resulting in a large amount of noise mixed in the acquired ECG signal and affecting diagnostic accuracy. Moreover, the connection between the electrode patch and the lead wire is not stable enough, and it is easy to loosen or fall off during use, causing signal interruption. Based on these issues, a disposable flexible ECG electrode patch was designed. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this invention provides a disposable flexible ECG electrode patch. Both the medical-grade polyurethane substrate and the hydrogel material have good biocompatibility, reducing the possibility of skin allergies. The snap-on design of the metal connector pin and metal connector female ensures a stable connection, preventing loosening or detachment during use.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A disposable flexible ECG electrode patch includes: a flexible substrate layer with a receiving space; an electrode layer assembled within the receiving space, and having a metal connector buckle; a conductive adhesive coated on one side of the flexible substrate layer and surrounding the electrode layer; a buffer layer assembled on the opposite side of the electrode layer and the conductive adhesive, and having a first clearance hole for avoiding the metal connector buckle; and a patch layer assembled on the opposite side of the buffer layer and the flexible substrate layer, having a metal connector female buckle; wherein the metal connector buckle and the metal connector female buckle are engaged and fixed.

[0006] By adopting the above solution, both the medical-grade polyurethane substrate and the hydrogel material have good biocompatibility, reducing the possibility of skin allergies. The snap-on design of the metal connector male and female ensures the stability of the connection and prevents loosening or detachment during use.

[0007] Furthermore, the electrode layer is made of silver-silver chloride material.

[0008] By adopting the above scheme, silver-silver chloride materials exhibit good electrical conductivity and electrochemical stability.

[0009] Furthermore, the flexible substrate is made of medical-grade polyurethane film, and the bottom surface of the electrode layer is flush with the bottom surface of the conductive adhesive.

[0010] By adopting the above scheme, the medical-grade polyurethane film has good flexibility and biocompatibility, and can be adapted to the curved surface of human skin. Moreover, this design allows the electrode layer to directly contact the skin, ensuring sufficient contact area for collecting electrocardiogram signals.

[0011] Furthermore, the buffer layer is bonded and fixed to the flexible substrate layer and the patch layer by hydrogel.

[0012] By adopting the above method, the hydrogel has certain elasticity and moisture retention, and the adhesion is firm.

[0013] Furthermore, a wire is connected to the metal connecting nut.

[0014] By adopting the above solution, a stable electrical connection is formed between the metal connector male buckle and the metal connector female buckle, preventing loosening.

[0015] Furthermore, it also includes a release paper layer, which is bonded to the conductive adhesive.

[0016] By adopting the above solution and setting a release paper layer, the electrode patch is protected before use.

[0017] Furthermore, the release paper layer is made of silicone oil coated paper.

[0018] By adopting the above solution, the adhesion between the silicone oil coated paper and the conductive adhesive is moderate, making it easy to peel off during use. Attached Figure Description
