Embodiment 1

[0022] A preparation method of anti-adhesion medical antibacterial gauze for treating burns includes the following steps:

[0023] Preparation of the antibacterial liquid: prepare Daqingye and Houttuynia cordata to decoct together with water four times the weight of the Chinese medicinal materials for 2 hours, and then filter the decocted medicinal liquid to obtain a residue-free medicinal liquid for use;

[0024] Preparation of antibacterial extract: place the medicinal solution in a low-temperature and reduced-pressure environment and concentrate to 1 / 4~1 / 5 of the original volume;

[0025] Gauze activation treatment: Use 4-6 mol / L sodium hydroxide solution to soak for 5-10 mi, and then immerse it in a toluene solution containing 5% bromoisobutyryl bromide after full activation, so that it has the activity of initiating ATRP polymerization;

Abstract

The invention provides a preparation method of an anti-adhesion medical antibacterial gauze for treating burns, and belongs to the field of medical dressing processing. The preparation method comprises the following steps of antibacterial extracting solution preparation, gauze activation and modification treatment, mixed soak solution preparation and gel layer infusion. According to the preparation method, natural antibacterial matters in the traditional Chinese medicines are extracted through a boiling mode and are then filtered and concentrated to obtain an antibacterial medical solution, then the antibacterial medical solution, citric acid, glycerol and a sodium alginate solution are mixed, then an ordinary medical gauze with polyacrylic acid surface modification is soaked in mixed liquid, and the gauze soaked with the mixed liquid is taken out after being fully soaked and is treated by freeze drying to obtain a novel anti-adhesion high moisture-absorbent medical antibacterial gauze for treating the burns. The preparation method is simple and is liable in industrialization.

Description

Technical field [0001] The invention relates to the field of medical material processing, in particular to a preparation method of anti-adhesion medical antibacterial gauze for treating burns. Background technique [0002] The gauze commonly used in clinic has the problems of extremely poor antibacterial ability, susceptibility to infection, poor hygroscopicity, and prone to stuffiness. It also has the problem that new granulation tissue easily grows into the mesh of the gauze. It is adequate for ordinary patients with small or not serious wounds, but For burn patients, due to their large wounds and severe ulceration, ordinary medical gauze is difficult to isolate and protect the wound, and it will also seriously affect the healing of burn wounds. In severe cases, it will cause secondary damage to the wound and bring the patient Come more painful. [0003] In addition, most of the burn-specific gauze mentioned in many papers and documents has many processing steps, high cost, and ...
