Abstract

The invention relates to a self-electroosmosis hydrogel adhesive film, which combines an electrochemical primary batter consisting of two polar materials with different electrochemical potential difference with functional active substance-containing hydrogel. A method for manufacturing the self-electroosmosis hydrogel adhesive film comprises the following steps of: printing conductive paste on an organic film to form a collector layer; producing a positive electrode layer and a negative electrode layer and printing the positive electrode layer and the negative electrode layer on the collector layer respectively; adhering all the layers on a non-woven fabric substrate; coating a conductive adhesive layer on the two electrodes respectively; and coating a functional active substance-containing hydrogel layer on the conductive adhesive layer. During use, the hydrogel adhesive film is contacted with the skin of a human body, and the two electrodes and the skin of the human body form a current loop through the hydrogel comprising a certain amount of moisture, so that permeation rate of the active substance can be increased and the adsorption rate of the skin on the active substance can be increased. The hydrogel adhesive film has the advantages of overcoming the defects that a power supply needs to be added, the film cannot be used at any time and the cost is high in the conventional ion permeation technique, and effectively increasing the permeation rate of the functional active substance, along with simple structure, low cost, convenient storage and carrying and convenient use.

Description

technical field [0001] The invention relates to a hydrogel patch with an electrochemical primary battery for skin care, auxiliary medical treatment and beauty treatment and a preparation method. Background technique [0002] The hydrogel currently used in skin care, medical treatment and beauty belongs to the transdermal penetration system, which refers to a type of product that takes effect through skin application, and the active substance is absorbed by the skin and enters the body fluid circulation to achieve the purpose of use and the purpose of drug delivery. . Specifically, the hydrogel containing auxiliary treatment or beauty liquid is directly coated and pasted on the skin surface, and the transparent or translucent colloidal liquid or ointment forms a temporary airtight barrier between the skin and the outside world, making the skin When the temperature rises, the pores open, the blood circulation of the skin is strengthened, and the skin appendages, namely hair f...
