Problems solved by technology

[0003] The main cooling components of existing antipyretic patches are water, menthol and borneol; and menthol and borneol, as traditional Chinese medicine, contact with the skin, can stimulate human skin or mucous membranes, and cause skin and mucous membrane vasoconstriction. Therefore, most existing products generally There is a rapid cooling effect, which causes the skin temperature to drop too fast, thus causing discomfort to the patient and causing certain side effects when used
At the same time, most products do not have the disadvantages of rapid response temperature sensitivity, short action time, poor persistence, etc.

Abstract

The invention belongs to the technical field of medicines, and particularly relates to a medical gel patch. The medical gel patch sequentially comprises a non-woven fabric lining layer, a CPP embossed film and a gel layer located between the non-woven fabric lining layer and the CPP embossed film from inside to outside, and the gel layer comprises cool micro-capsules; the cool-feeling micro-capsule comprises a cool-feeling agent and plant essential oil. The invention also provides a preparation method of the gel layer and a preparation method of the medical gel patch. The composition of the gel layer is improved, and the microencapsulation technology is adopted, so that the patch has a better effect of regulating the body temperature.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a medical gel patch. Background technique [0002] The antipyretic paste is a physical cooling product. With its fast antipyretic and good cooling effect, it is accepted and used by more and more people. The basic structure of the antipyretic patch consists of a material film, a non-woven fabric and a gel layer. The cooling principle is mainly that the polymer hydrogel contained in the gel layer can concentrate the heat into the colloid, absorb heat through the evaporation of water in the gel, and take away the heat on the body surface, so as to achieve the effect of cooling and antipyretic. It has the dual effect of physical cooling and natural cooling agent cooling. It is widely used in children with fever, sprains and high temperature work. [0003] The main cooling components of the existing antipyretic patches are water, menthol and borneol; and menthol and b...
