Medical liquid dressing and preparation method thereof

Abstract

The invention discloses medical liquid dressing and a preparation method thereof, and aims at providing the medical liquid dressing which has long-acting antibacterial effects, the capability of reducing formed scars and has a good treatment effect on wound healing. The medical liquid dressing is characterized by containing 0.02-1% of solid ingredients and the balance of water; the solid ingredients include 10-80% of chitosan quaternary ammonium salt, 20-90% of organosilicon quaternary ammonium salt, and 6-30% of auxiliary materials. The preparation method comprises the steps of adding water to an agitating tank, setting the agitating speed of the agitator to 30-35 r / min; firstly, adding chitosan quaternary ammonium salt to agitate and completely dissolve for about 2-3 hours; adding an organosilicon quaternary ammonium salt solution and a chlorhexidine gluconate solution when agitating, fully agitating for 1-2 hours to obtain a mixing solution; filtering the mixing solution in a container; removing air bubbles over a night; determining a semi-finished product of which the solid content is 0.02-1% and the PH value is 4.1-7.5 in the next day; and sub-charging in bottles to form the finished product after a sterile test is qualified. The medical liquid dressing belongs to the technical field of preparation of medicaments.

Description

technical field [0001] The invention discloses a dressing and a preparation method thereof, in particular to a medical liquid dressing and a preparation method thereof, belonging to the technical field of medicine preparation. Background technique [0002] Wound healing is a complex process, which is affected by many factors, such as infection, wound pollution, autoimmunity, etc. Among them, infection is the most common factor, and infection is the main reason affecting wound healing. Therefore, it is very necessary to create a good environment for wound healing and prevent wound infection.
