Anti-adhesion hygroscopic medical acid-sensitive antiseptic gauze and preparation method thereof

Abstract

The invention discloses a piece of anti-adhesion hygroscopic medical acid-sensitive antiseptic gauze and a preparation method thereof, and belongs to the fields of medical gauze and a preparation method thereof. The piece of gauze comprises a medical gauze base material and a gel layer adhered onto the medical gauze base material, wherein the gel layer is prepared from a mixed soaking solution; the mixed soaking solution comprises an antibacterial traditional Chinese medicine extract, sodium alga acid, citric acid, glycerin and water; the antibacterial traditional Chinese medicine extract is a complex extract of folium isatidis and herba houttuyniae. The preparation method comprises the following steps: boiling, filtering and concentrating to obtain the antibacterial traditional Chinese medicine extract; mixing the antibacterial traditional Chinese medicine extract, citric acid, glycerin and sodium alga acid solution to obtain a mixed solution; immersing ordinary medical gauze in the mixed solution, fully wetting the medical gauze, taking out the medical gauze, and drying the medical gauze in a drying oven. The preparation method is simple, and the prepared medical gauze has an anti-adhesion hygroscopic effect, is acid-sensitive and has an antibacterial effect.

Description

technical field [0001] The invention relates to the field of medical gauze and a preparation method thereof, in particular to an anti-adhesion hygroscopic medical acid-sensitive antibacterial gauze and a preparation method thereof. Background technique [0002] Medical gauze is mainly used to bandage wounds in the field of health care to protect and protect wounds. However, in the course of clinical use, there are many technical problems in medical gauze, which are mainly reflected in the following aspects: 1. The gauze has poor hygroscopicity and cannot effectively absorb wound exudate, causing the exudate to solidify at the wound, affecting the healing of the wound 2. The anti-adhesion effect of gauze is relatively poor, so that new granulation tissue is easy to grow into the mesh of gauze, which will not only cause secondary damage to the wound surface when changing gauze, but also be unfavorable for wound healing and bring greater misery to the patient 3. The release be...

However, in the course of clinical use, there are many technical problems in medical gauze, which are mainly reflected in the following aspects: 1. The gauze has poor hygroscopicity and cannot effectively absorb wound exudate, causing the exudate to solidify at the wound, affecting the healing of the wound 2. The anti-adhesion effect of gauze is relatively poor, so that new granulation tissue is easy to grow into the mesh of gauze, which will not only cause secondary damage to the wound surface when changing gauze, but also be unfavorable for wound healing and bring greater misery to the patient 3. The release behavior of antibacterial agents loaded on gauze is not responsive to the bacterial growth environment, resulting in excessive use of antibiotics, increasing toxic side effects and aggravating the emergence of bacterial drug resistance. At the same time, studies have shown that the microenvironment of bacterial growth,
