Problems solved by technology

At present, hydrogel self-adhesive electrode pads made of hydrogel are widely used clinically, but there are also the following problems: 1. Viscosity: the electrode pads are too weak, and the patient will easily fall off during treatment, and the viscosity is too high. If it is strong, the patient will feel tearing pain or there is residual glue on the skin when it is removed after treatment. The adhesiveness of the currently prepared hydrogel electrode sheet is not very good; 2. Conductivity: the existing gel electrode sheet Poor electrical conductivity, high resistance, uneven electrical conductivity, especially for electrodes coated on the surface; 3. Raw materials: slightly irritating to the skin, causing tingling, pollution, discomfort, allergies, etc.; some rubber raw materials also have Slight environmental pollution and even some raw materials are toxic and carcinogenic; 4. Cost: high production cost and complex equipment requirements
[0003] Chinese invention patent CN108815538A discloses a conductive electrode sheet and its preparation method. Although the prepared electrode sheet has strong application ability and no irritation to the skin, its raw materials use flammable, neurotoxic, carcinogenic acrylic acid, and strong Corrosive raw material potassium hydroxide, low safety performance

Abstract

The invention discloses a physiotherapeutic electrode slice and a preparation method thereof, relates to the technical field of physiotherapeutic electrode slices. The physiotherapeutic electrode slice comprises the following raw materials, in parts by weight, 2.0*104 to 3.5*104 parts of acrylamide, 4.0*104 to 6.0*104 parts of glycerol, 0.5 to 1.0 parts of cross-linking agent, 0.75 to 2.0 parts ofphotoinitiator, 40 to 80 parts of N,N-methylene bisacrylamide, 3.0*104 to 6.0*104 parts of purified water, and 0.8*103 to 1.2*103 parts of strong electrolyte inorganic salt. The preparation method comprises steps of dissolving the acrylamide in the purified water; adding the glycerin and stirring the mixture; adding an aqueous solution of the N,N-methylene bisacrylamide, an aqueous solution of the strong electrolyte inorganic salt, and a mixed solution of the cross-linking agent and the photoinitiator; and stirring, and solidifying, slitting the mixture. The method dissolves the N,N-methylenebisacrylamide and the strong electrolyte inorganic salt in water and then mixes the same with other ingredients, thereby improving the solubility of the N,N-methylene bisacrylamide and the strong electrolyte inorganic salt in the system, and enhancing the viscosity and conductivity of the adhesive. The obtained electrode slice gel has moderate hardness, good viscosity, good attachment capability.The raw materials are safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of physiotherapy electrode sheets, in particular to a physiotherapy electrode sheet and a preparation method thereof. Background technique [0002] Physiotherapy using electrode sheets is one of the commonly used methods for physical therapy. The existing electrode sheets are attached to the body by two electrode sheets during use, and are powered on respectively. A path is formed between the two electrode sheets to achieve the effect of physical therapy. At present, hydrogel self-adhesive electrode pads made of hydrogel are widely used clinically, but there are also the following problems: 1. Viscosity: the electrode pads are too weak, and the patient will easily fall off during treatment, and the viscosity is too high. If it is strong, the patient will feel tearing pain or there is residual glue on the skin when it is removed after treatment. The adhesiveness of the currently prepared hydrogel electrode sh...
