Abstract

The invention relates to an externally applied preparation for treating skin wound, in particular to an externally applied preparation for treating chronic skin ulcer, which is characterized in that it comprises the effective components in weight as follows: insulin 500-5000u / 1000g, epidermal growth factor 0.001-0.01g / 1000g, antibacterials 5-20g / 1000g, others are adjuvant. It can treat a variety of infectious and protracted skin ulcer safely and effectively.

Description

technical field [0001] The present invention relates to an external preparation for treating skin wounds, in particular to an external preparation for treating intractable skin ulcers. Background technique [0002] Chronic intractable skin ulcer is a common disease, which is a localized defect of the skin and subcutaneous tissue or mucous membrane caused by a variety of reasons, often accompanied by different degrees of infection. Due to the long course of disease and the malnutrition of the wound, it is difficult to achieve natural healing of intractable ulcers. In my country's population aged 14 to 64, the incidence of chronic skin ulcers was 9.2% in men and 6.6% in women. The skin ulcer complicated by diabetic patients is a relatively stubborn chronic ulcer with tissue necrosis and local infection. The pathogenesis is complex. The main pathogenic factors include: vascular disease leading to ischemia and hypoxia; peripheral neuropathy leading to foot protective sensation ...
