Abstract

The invention relates to the technical field of medical articles, and discloses a medical cold compress patch raw material and a preparation technology. The medical cold compress patch raw material comprises, by weight, 0.8-1.6 parts of carrageenan, 0.2-0.6 part of sodium polyacrylate, 8-14 parts of glycerinum and 80-100 parts of purified water. The purified water and sodium polyacrylate are sequentially added into a liquid dispensing box, and a stirring plate is driven to perform stirring to prepare a sodium polyacrylate solution; the liquid dispensing box is heated to a preparing temperature, the stirring plate continues to perform stirring, menthol and the carrageenan are sequentially added into the sodium polyacrylate solution, heating stirring is performed, and finally mixed liquid isobtained; the glycerinum is added into the mixed liquid, uniform stirring is conducted, and a cold compress patch stock solution is obtained; the cold compress patch stock solution is guided into a refrigerating box, and standing cooling and forming are performed. The medical cold compress patch raw material solves the problem that the cooling effect of a cold compress patch product in the priorart is poor.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical cold compress raw material and a preparation process. Background technique [0002] Cold compress is a more economical cold compress therapy through physical cooling. Traditional cold compress methods mainly use ice water, ice cubes, alcohol, etc., but these methods have short cold compress time, large dosage, uneven cold compress effect, easy to cause local frostbite, and are inconvenient to carry and store. [0003] The cold compress is improved according to the traditional cold compress method (cold water, ice water or alcohol). It takes away the heat through the vaporization of the water contained in the polymer gel and the natural cooling ingredients, and can achieve local cooling. Combined with the gel, through hydration, the drug ingredients can quickly pass through the fat layer, penetrate into the subcutaneous tissue, directly reach the lesion site, a...
