Wound protecting composition with bleeding-stopping and anti-bacterial functions and preparation method of wound protecting composition

Abstract

The invention discloses a wound protecting composition with bleeding-stopping and anti-bacterial functions and a preparation method of the wound protecting composition. The wound protecting composition comprises the following steps: (1) preparing an organic high molecular mixed solution; (2) adding one or two of chitosan and chitin into acetic acid, ethanol and water so as to prepare a bleeding-stopping and anti-bacterial material solution; (3) carrying out multi-spray-head electrostatic spinning so as to prepare a composite fiber material; and (4) drying the composite fiber material, removing residual solvents, and carrying out hot-press shaping, so as to prepare the wound protecting composition with the bleeding-stopping and anti-bacterial functions. The wound protecting composition disclosed by the invention has good bleeding-stopping and anti-bacterial effects, can be used for cleaning wounds and is good in biocompatibility; the water absorption rate is obviously increased, the bleeding-stopping time is greatly shortened, and the wounds are further protected.

AI Technical Summary

Benefits of technology

This patented process allows create a special type of product that can stop bleeding quickly without causing any harm during surgery. It consists mainly three main parts - it includes various components like plastic films made from hydroxyethyl cellulose (HEC), EDTA, citric acid, glucosamine, etc., which are combined together by mixing them under specific conditions such as temperature, pressure, pH value, ion concentration, and chemical reaction parameters. These compositions have several beneficial properties including enhanced ability to prevent clotting when applied externally over large areas of skin surface caused by excessive swelling due to external factors like heat stress, inflammations, and tissue damage.

Problems solved by technology

This patents discusses various types of procedures performed after surgeries like those involving open abdomens where blood vessels cannot easily penetrate without causing damage due to lack of oxygen supply. Existing techniques involve cutting off these cuts before closing them, making cleanup steps unnecessary. Additionally, current dressings often require frequent changes overtime, leading to increased risk of complications. There has developed compositions made up entirely of biodegradables that provide quick heals when applied through stitching instead of sewing. These composites offer advantages compared to traditional gauzes, reducing patient discomfort and promotes faster recovery times.
