Problems solved by technology

[0005] The technical problem mainly solved by the present invention: Aiming at the current adverse thermal reaction of the human body due to hypothermia or sudden drop in body temperature after burns and scalds, traditional methods generally adopt measures such as hot compress or infrared radiation to cool down, but due to the weakened body temperature regulation ability, especially When there are no external heat preservation or cooling measures, there will be repeated rises or falls in body temperature, which will endanger human health and safety. However, traditional dressings only have the effect of protecting wounds, but do not have the function of heat preservation. Micro-deformation phase-change fillers are prepared by coating polyethylene glycol, supplemented with cellulose acetate after electrospinning, and spunlace reinforcement, so as to obtain special thermal insulation dressings for scald wounds

example 1

[0021] First, measure 50 mL of sulfuric acid with a concentration of 0.5 mol / L and 40 mL of nitric acid with a concentration of 0.3 mol / L, mix them evenly, and pour them into a 200 mL beaker. Continue to add 20 g of fine flake graphite powder into it, stir with a glass rod for 20 minutes, and then add 5 g Potassium permanganate and 3 g of ferric chloride were stirred with a magnetic stirrer for 2 hours to oxidize the graphite; then the oxidized graphite was moved into a Buchner funnel, washed with distilled water and filtered until the pH reached 6, then the graphite was placed in an oven After drying at 105 °C for 1 h, the dried graphite was put into a high-temperature expansion furnace, and expanded instantly at 800 °C to obtain expanded graphite; then 50 g of polyethylene glycol was weighed and dissolved in 200 mL of distilled water, and heated in a water bath. To 70 ° C, 40 g of the expanded graphite prepared above was poured into the polyethylene glycol solution, placed on...

Abstract

The invention belongs to the technical field of dressing preparation and discloses a preparation method of a special thermal dressing for scald wounds. The method includes steps: using expanded graphite for coating polyethylene glycol to obtain micro-deformation phase-change filler, and performing cellulose acetate electrostatic spinning and spunlace reinforcement to obtain the special thermal dressing for scald wounds. The method is convenient and simple in operations, raw materials are easy to acquire, and the special thermal dressing for scald wounds not only has excellent biocompatibility but also has advantages of softness, sanitation, breathability, moisture absorptivity and hairiness avoidance. In addition, after use of the special thermal dressing, a warm and comfortable environment is provided for the wounds, healing of the wounds can be accelerated, and the special thermal dressing has an extensive application prospect.

Description

technical field [0001] The invention discloses a preparation method of a special thermal insulation dressing for scald wounds, and belongs to the technical field of dressing preparation. Background technique [0002] Burns and scalds are a complex surgical disease caused by the action of boiling water, boiling oil, fire, electricity or acid-base substances on the human skin. Generally, fire burns and boiling water or oil burns are common. In mild burns or scalds, the epidermis is red, swollen, sore, or blistered; in severe burns and scalds, due to damage to the skin and subcutaneous tissue, the fire poison damages the yin fluid in the body, attacks the internal organs, damages the yin and damages the yang, and often causes damage to the human body. Water and electrolyte imbalance, shock, skin tissue redness, ulceration, infection and other serious consequences. If the wound is not treated in time, the infection will not heal for a long time, resulting in scarring and affect...
