Description

Technical Field

[0001] The utility model relates to an electrode sheet, in particular to a flexible skin-feeling electrode sheet. Background Art

[0002] With the rapid development of the medical beauty technology industry, more and more new treatment technologies are applied in the field of medical beauty, such as radiofrequency treatment, EMS (Electric Muscle stimulation) treatment, laser treatment, and so on. Among them, radiofrequency and current stimulation electrode sheets are particularly widely used in beauty treatment. By applying radiofrequency electrodes or electrical stimulation electrodes, local collagen proliferation can be stimulated, and the metabolism of the skin can be accelerated, so as to lighten the symptoms of acne marks, skin pigmentation, and skin wrinkles, making the skin smoother and more delicate.

[0003] The existing electrode sheets generally include radiofrequency electrodes or electrical stimulation electrodes, and the treatment is carried out after the electrode sheet is attached to the skin. However, the existing electrode sheets do not match well with the contour of the human face, and there are often problems of poor adhesion to the facial skin when the electrode sheet is attached, which is likely to result in poor treatment effects, or even skin burns, and the expected treatment effects cannot be achieved.

[0004] In the prior art, Chinese Patent Publication No. CN220530506U discloses a flexible electrode sheet, a flexible electrode sheet assembly and a therapeutic apparatus. Among them, the flexible electrode sheet is used to attach to and treat the cheek skin. The flexible electrode sheet includes a base, a plurality of radiofrequency electrodes and a plurality of electrical stimulation electrodes; at least part of the cross-sectional shape of the base is arc-shaped, and one end of the base is recessed towards the other end to form a groove; a plurality of radiofrequency electrodes are all arranged on the flexible electrode sheet at intervals and are electrically connected to an external power supply for generating radiofrequency energy; a plurality of electrical stimulation electrodes are all arranged on the flexible electrode sheet at intervals and are electrically connected to an external power supply for generating microcurrents. The technical solution of this utility model solves the problem that the existing flexible electrode sheet often has poor adhesion to the facial skin during the fitting treatment, and improves the treatment effect. However, the flexible electrode sheet is not provided with an adhesive skin-feeling cotton layer and a hydrogel layer, so the comfort is not strong when the customer uses it, and an insulating barrier layer is not correspondingly provided, and the safety performance cannot be guaranteed.
