The present invention relates to a technical field of medical supplies, particular to a medical cold compress patch and preparation method thereof.
In traditional cold compress physiotherapy methods ice cubes or ice cube composites (commonly referred to as ice packs) are generally applied to the affected area or specific parts so that the purposes of cold compress and pain relief are achieved, but they are of short cold application time, large consumption, and uneven cold effect. When they are applied to infants or certain special parts, patients are prone to be uncomfortable and even get localized frostbite. At the same time, those products are inconvenient to carry and could be used at limited time or place, and the person must maintain a certain posture and could not move when using.
The cold compress patch obtained by improving the traditional cold compress method (like cold water, ice water, alcohol, etc.) and centered on a new drug release system TDDS which is prepared on the basis of polymer gel, comprises a backing layer, a gel layer, and a covering layer. The water and natural cooling component contained in the polymer gel vaporize to absorb the heat so that localized cooling is achieved, and the drug therein combined with the hydrogel allows the ingredients to penetrate the fatty layer quickly through the hydration, permeate into the subcutaneous tissue, directly reach the lesion site, and act on the affected area thereby achieving the effects of cold compress, percutaneous absorption and sustained release of the drug.
Ordinary cold compress patch is mainly suitable for early local soft tissue injury, high-heat patients and heatstroke, toothache and other people who need cold compress, but fails to quickly repair skin tissue and promote wound healing, in addition, due to the simple size and shape, ordinary cold compress could not meet the needs of different users.
