Description

A kind of biomaterial composite hydrogel wound dressing and preparation method thereof technical field The invention belongs to medical dressing technical field, relate in particular to a kind of biomaterial composite hydrogel wound dressing and its Preparation. Background technique The skin is the largest and outermost organ covering the entire body, and its main function is to protect the underlying muscles, bones, and Bands and internal organs are protected from external biological, chemical, mechanical and physical factors. [0003] In addition, the skin is involved in sensation, thermoregulation, immune surveillance, protection from dehydration, and contributing to the synthesis of vitamin D3. Of course However, the structure and function of the skin can be affected by trauma, burns, surgical incisions or diseases such as diabetes. skin structure Wounds form after injury, and their structure and function must be rebuilt as quickly as possible to ensure body ho...
