Abstract

The invention discloses a medical cold compress patch. The medical cold compress patch is prepared by attaching an effective component to a non-woven fabric or a silk cloth and then carrying out freeze drying; the effective component comprises a cooling composition and a moisturizing composition; the cooling composition contains borneol, menthol and camphor. The medical cold compress patch does not contain moisture, it is not needed to add a preservative, and the skin damage or allergic phenomenon caused by the preservative can be reduced; the medical cold compress patch is more flexible to use, the wetting time is short, and the medical cold compress patch can be used after being wetted in combination with clean water or other nutrient water. The cold compress patch obtained after freezedrying treatment can reduce the loss of heat sensitive substances, some oxidizable substances in the cold compress patch are protected, and the stability of the cold compress patch is improved. The cold compress patch is applicable to physical defervescence and cold compress physiotherapy of closed soft tissue. Heat is removed by vaporization of moisture and natural cooling components contained bythe cold compress patch, and the effects of pain reliving through cold compress, percutaneous absorption and slow-release drug delivery can be achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical cold compress. Background technique [0002] The cold compresses on the market are improved based on traditional cold compress methods (such as cold water, ice water, alcohol, etc.), and the TDDS new drug release system prepared on the basis of polymer gel is the core. Generally, it consists of a backing layer, a gel Layer, anti-adhesive layer composition. Through the vaporization of the water contained in the polymer gel and the natural cooling ingredients to take away the heat, local cooling can be achieved. The drug ingredients in it are combined with the hydrogel, and through hydration, the drug ingredients can quickly penetrate the fat layer. It penetrates into the subcutaneous tissue, directly reaches the lesion, acts on the affected area, and achieves the effects of cold compress to relieve pain, percutaneous absorption, and sustained release. These cold compresses on the ma...
