Method for preparing medical dressing

Abstract

The invention discloses a preparation method of a medical dressing used for treating burns and scalds after operation. Combining 60-70% (w / w) of carboxyvinyl polymer and 40%-30% (w / w) of lauryl polyoxyethylene ether into a polymer compound is group A, and take 40-50ml of propylene glycol and 40-50g of glycerin , 60-70g of liquid paraffin and 1000ml of purified water are mixed under high-shear stirring to make a mixed liquid group B, take 20-30g of emulsified silicone oil and 10-20g of water-soluble laurozone to make a mixed group C, take 20-30g of tea tree oil and water-soluble tea tree dew 300-500g to make solution group D after stirring and strengthening, then place group A in a slow-stirring reaction kettle and add group B, group C and group D respectively to form a gel-like sol. Soak the sol into medium-density polyurethane sponge or degreasing gauze, wool felt, various medical non-woven fabrics and seal the package. It can promote skin metabolism, antibacterial, sterilizing, moisten the wound, relieve pain, no sticky feeling, accelerate wound healing, and minimize external skin damage.

Description

Technical field

[0001] The invention relates to a preparation method of a medical dressing used for treating burns and scalds after surgery. Background technique

[0002] At present, clinically, after the treatment of burns and scalds, various drugs are added with Vaseline gauze to treat burns and scalds. This method not only uses too much gauze, but also affects the normal healing of wounds due to resistance to various drugs. Summary of the invention

[0003] To solve the above problems, the present invention provides a medical dressing prepared by using tea tree oil and emulsifier as main materials.

[0004] The present invention is a method for preparing medical dressings. In a sterile air purification environment, carboxyvinyl polymer and lauryl polyoxyethylene are etherified to synthesize high molecular compounds into group A, and propylene glycol, glycerin, liquid paraffin and purified water are taken. Make the mixed solution group B under high-shear stirring, take the emu...
