Abstract
The invention belongs to the field of medical supplies, and particularly relates to a medical cold compress patch. The medical cold compress patch comprises a backing layer, a gel layer and a coveringlayer, wherein the backing layer is a non-woven fabric, the covering layer is a polyethylene film, and the gel layer is prepared from polyvinyl alcohol, a skin moistening agent, an accelerant and purified water; the skin moistening agent is prepared from a moisturizing agent and an auxiliary agent; the moisturizing agent is prepared from glycerol and trehalose; the auxiliary agent is selected from one or more of sodium chloride, sodium hyaluronate and ceramide; the accelerant is borneol or a combination of borneol and allantoin. The invention also provides a preparation method of the medicalcold compress patch. The medical cold compress patch provided by the invention can maintain the skin moisture, prevent evaporation of skin moisture of the body surface, resist various external stimulations, relieve skin allergy, alleviate hyperpigmentation and other skin problems, and can prevent the invasion of microorganisms on the skin surface.
Description
technical field [0001] The invention belongs to the field of medical supplies, and in particular relates to a medical cold compress and a preparation method thereof. Background technique [0002] The skin is the first barrier between the body and nature, which can prevent the invasion of environmental pathogenic microorganisms and the loss of body fluids. The skin is also a very important organ of the body. A healthy skin barrier can resist the entry of external harmful substances, irritants and sunlight. Damage to its physical barrier will cause dry skin, skin aging, pigmentation, atopic dermatitis, eczema, silver Psoriasis, fish phosphorus disease, solar dermatitis and other skin sensitivity, irritant dermatitis and other diseases. [0003] Medical cold compresses are improved based on traditional cold compress methods (such as cold water, ice water, alcohol). They are prepared on the basis of polymer gels and do not contain ingredients that exert pharmacological, immunol...
