Abstract

The invention provides a preparation method of a dressing suitable for burns. The preparation method comprises the following steps: obtaining a porous material in a heating and foaming treatment manner for natural polymers; and compounding the porous material with a film-like bio-absorption membrane. The preparation method provided by the invention is simple to operate and solves a problem that the dressing is not suitable for burns or scalds in the prior art; the prepared hemostatic dressing has excellent biocompatibility, fits with a wound surface well, can isolate external bacteria, and better promotes healing of the burns or the scalds.

Description

technical field [0001] The invention relates to the medical and health field, in particular to a preparation method of a dressing suitable for burns. Background technique [0002] Scalds or burns are collectively referred to as "burns", which are common traumas that not only cause damage to the skin, but also can cause severe systemic reactions, especially for large-scale burns. The systemic reactions are very severe, such as fluid leakage, infection, Absorption of toxins, etc. may cause metabolic disorders and dysfunction of various systems and organs, and high mortality. At the same time, if the burn wound is not treated properly (such as red lotion, toothpaste, dog oil and some traditional Chinese medicine prescriptions, etc.), it is easy to cause wound infection, deepen the wound, and prolong the healing time of the burn, which will increase the pain of the patient and form scars or scar hyperplasia. , contractures and other sequelae such as deformity, dysfunction, and ...
