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 field of medical equipment and daily chemical technology. Background technique [0002] For many years, apply hydrogel to the affected area or apply gauze soaked in magnesium sulfate solution to the affected area for subcutaneous exudate swelling, pain and phlebitis caused by intramuscular injection and infusion, inflammation and swelling of soft tissue, inflammation and swelling caused by puncture adjuvant therapy. It has always been used by doctors. The commonly used hydrogel is currently used in adjuvant therapy to cool the surrounding tissues of the affected area with cold compresses, but the effect of adjuvant therapy is not as good as that of magnesium sulfate wet compresses. Magnesium sulfate wet compress needs to be prepared temporarily, which is inconvenient to operate and time-consuming. During use, the gauze is eas...
