Abstract

The invention discloses cold compress paster and a preparation method thereof. The cold compress paster comprises a backing layer as well as a hydrogel layer and an anti-adhesion layer which are adhered to the upper surface of the backing layer sequentially; the hydrogel layer is prepared from a hydrogel matrix and comprises the following oil phase and aqueous phase in parts by weight: oil phase: 18 to 22 parts of glycerinum, 4 to 7 parts of polyacrylic acid, 0.13 to 0.17 part of dihydroxyaluminum aminoacetate, and 1 to 5 parts of crosslinked polyvinylpolypyrrolidone (PVPP); aqueous phase: 65 to 69 parts of purified water, 0.1 to 0.5 part of ethylene diamine tetraacetic acid, 0.5 to 20 parts of anhydrous magnesium sulfate, 1 to 3 parts of polyvinylpyrrolidone (PVP) and 0.2 to 0.5 part of tartaric acid. According to the cold compress paster provided by the invention, the hydrogel layer integrates the traditional hydrogel cold compress and magnesium sulfate cold compress, so the cold compress paster has good auxiliary treatment effect, does not have any side effects and is convenient to use.

Description

Technical field [0001] The invention relates to a cold compress, in particular to a cold compress and a preparation method thereof. It belongs to the technical field of medical equipment and daily chemical industry. Background technique [0002] For many years, apply hydrogel to the affected area or apply gauze soaked in magnesium sulfate solution to the affected area. It is used for intramuscular injection and infusion caused by subcutaneous fluid swelling, pain and phlebitis, soft tissue inflammation swelling, inflammation and swelling caused by puncture Of adjuvant therapy. It has been used by many doctors. The currently commonly used hydrogels are used in adjuvant therapy to cool down the surrounding tissues of the affected area, but the adjuvant therapy is not as effective as magnesium sulfate wet compresses. Magnesium sulfate wet compress needs to be temporarily prepared, which is inconvenient to operate, delays time, gauze is easy to fall off during use, and water is eas...
