Abstract

The invention provides a preparation method of wound protecting liquid for treating skin ulcer. According to the method, firstly, chitosan is added into an acetic acid solution; under the stirring condition, polyvinylpyrrolidone, polyvinyl butyral and citric acid are added; dispersion is performed to obtain a mixed solution A; then, sodium alginate is added into deionized water 1; ultrasonic processing is performed; still standing is performed for 5 to 10 min at 5 to 10 DEG C to obtain a mixed solution B; then, borax, borneol and beewax are added into deionized water; stirring is performed to obtain a mixed solution C; finally, the mixed solution C is added itno a mixed solution B; stirring is performed; the pH is regulated to 7.0 to 8.0; the mixed solution A, the silicon oil, histidine and lignin are added; high-speed stirring is performed; still standing is performed; the wound protecting liquid is obtained. The wound protecting liquid provided by the invention can promote the wound heeling and can relieve the ulcer symptom; the surface can be safely observed. The wound protecting liquid provided by the invention does not have untoward effects on the skin and the mucosa.

Description

technical field [0001] The invention belongs to the technical field of surgical medicine, and in particular relates to a preparation method of a wound-protecting liquid for treating skin ulcers. Background technique [0002] Skin ulcer is a chronic infectious ulcer of the skin caused by various reasons. It is caused by tissue ischemia, necrosis, skin or point membrane defect, coupled with poor nutritional status of local tissue, blood circulation disorder and low resistance, resulting in repeated infection. , forming a vicious circle. Because of its characteristics such as protracted non-healing and extremely easy recurrence after healing, it has become a typical case that is difficult to cure in clinical medicine. [0003] The main components of wound dressing care solution are silver ions, polymer protective agent (gelatin), and deionized water to form a colloidal dispersion system. Silver ions can not only kill bacteria and virus propagules, but also kill fungi. The b...
