Abstract

The invention discloses a preparation method of a biological dressing capable of removing scars. The preparation method comprises the following steps: firstly weighing raw materials in parts by weight, placing the weighed raw materials in a reactor, and uniformly stirring the raw materials so as to obtain a mixture; pouring the uniformly mixed mixture into a membrane making mold, and performing scraping, sufficient drying, and demolding in sequence so as to obtain a medicine storage layer; finally bonding and composing the prepared medicine storage layer with a base cloth through a binder, and drilling holes in an adhesive compound material with a dense needle punching micro-hole machine; cutting the dense compound material after hole drilling into required shapes, and performing sealed sterilization. The biological dressing prepared by the method disclosed by the invention adopts a traditional Chinese medicine formula, so that the biological dressing is small in irritation, free from toxic and side effects, and good in biologic compatibility. Through reasonable compatibility, the biological dressing not only can resist the interference of external factors (such as bacteria and viruses), but also has the effects of promoting skin absorption, enabling pigments and scars less noticeable and the like, and is safe, mild and free from toxic and side effects.

Description

technical field [0001] The invention belongs to the field of new medical biological materials, and relates to a preparation method of a scar-eliminating biological dressing. technical background [0002] For a long time, scars have been one of the most concerned issues. Whether it is burns, scalds, surgery or other injuries, once the dermis is injured, scars will occur. Everyone has a desire for beauty, and the existence of scars has brought troubles to many people, especially young women. How to remove ugly scars and regain self-confidence is a matter of great concern to the scar family. At present, the commonly used scar removal methods in the beauty industry include surgical treatment, drug treatment and external application. However, surgical treatment is not suitable for many patients, and the risk is high; drug therapy, including internal medicine and external medicine, also generally has the disadvantage that the effect is not obvious enough. The external applicatio...
