A medical cold compress patch comprising a backing layer, a gel layer, and a covering layer, characterized in that the gel layer is consisted of various raw materials and each raw material is measured by mass percentage, 2 to 15 mass percent of macromolecule substance, 2 to 10 mass percent of epidermal growth factor, 2 to 8 mass percent of ceramide, 3 to 8 mass percent of humectant, 3 to 10 mass percent of bupleurum sinensis extract, 2 to 8 mass percent of dandelion extract, 3 to 12 mass percent of cortex phellodendri extract, 5 to 10 mass percent of aloe vera extract, 2 to 10 mass percent of honeysuckle flowers extract and the balance being purified water.
A preparation method of the medical cold compress patch, comprising the following steps of:
- Step A:
- accurately weighing and preparing each raw material for use according to the ratios of each raw material in the gel layer;
- Step B:
- dissolving the prepared epidermal growth factor, ceramide, humectant and aloe vera extract in water and mixing the solution evenly at a rate of 150-300 r/min for 15-30 min at normal temperature to obtain the constituent 1;
- Step C:
- dissolving the prepared macromolecule substance in water to swell the macromolecule substance at normal temperature for 20 min and stirring the solution evenly at a rate of 50-100 r/min for 10-20 min to obtain the constituent 2,
- Step D:
- dissolving prepared the bupleurum sinensis extract, dandelion extract, cortex phellodendri extract, aloe vera extract, and honeysuckle flowers extract in water and at normal temperature stirring the solution evenly at a rate of 100-200 r/min for 20-40 min to obtain the constituent 3;
- Step E:
- mixing above-mentioned three constituents and at normal temperature stirring the mixture evenly at a rate of 100-200 r/min for 20-40 min to obtain a clear gel;
- and
- Step F:
- coating the clear gel evenly on a backing layer and pressing a covering layer against the clear gel and cutting, solidifying and packing it to obtain the finished product of the medical cold compress patch
