Abstract

The invention discloses a biofunctional dressing and a preparation method thereof. The method comprises steps as follows: a gelling substance and a functional substance containing an onion extract, honey and propolis are added to a solvent B, the mixture is heated to be dissolved into a gelatinous or pasty functional matrix, an acid-base indicator and a pH conditioner are added to the functional matrix, a functional solution with the pH ranging from 3.0 to 5.5 is formed and then infiltrated into a functional layer base material, a dressing piece is formed, two sides of the dressing piece are coated with films, packaging and sterilization are performed, and the biofunctional dressing is obtained. The biofunctional dressing prepared with the method can remind a user of replacement time, has no irritation to skin, is good in bio-compatibility, natural and anti-bacterial and has scar removal and skin whitening functions, and the raw materials are widely sourced.

Description

technical field [0001] The invention relates to a medical functional dressing, in particular to a biological functional dressing and a preparation method thereof. Background technique [0002] An ideal medical dressing not only needs to create a good microenvironment for wound healing, has good permeability, can block external foreign matter and microbial contamination, and will not cause secondary pollution when replaced; it also needs to allow medical staff and patients Keep abreast of wound conditions, remind medical staff and patients to change dressings and understand wound conditions. [0003] For some chronic wounds (such as burns, ulcers, diabetic feet, etc.), such wounds generally have a lot of wound exudate, and slow wound healing requires patients and medical staff to change dressings regularly. At present, wound dressings cannot provide or provide timely feedback on wound healing and exudate, etc., so whether the wound needs to be replaced and when to replace it...
