Abstract

The invention discloses a collagen-loaded alginate medical dressing and a preparing method thereof, and belongs to the technical field of medical dressings. Firstly, collagen is added into a certain amount of pure water, and the mixture is fully stirred to completely dissolve the collagen into the water; then a certain amount of ethanol is added into the aqueous collagen solution, and the mixtureis fully stirred and uniformly dispersed; and finally the obtained collagen solution with a water-ethanol mixture system is added into a mist spraying device and an alginate non-woven fabric is sprayed uniformly with the solution, and aired naturally to obtain the medical dressing. The prepared medical dressing when used for wound nursing has excellent properties of alginate medical dressings andthe collagen, and has advantages of capabilities of accelerating wound healing, reducing scar formation, relieving wound pain, preventing adhesion with wounds, and the like.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a method for preparing a collagen-loaded alginate medical dressing. Background technique [0002] In daily life, there are many types of wounds, including burns caused by mechanical, electrical, thermal, chemical and other factors, as well as chronic trauma due to the patient's physiological pathology. Chronic wounds such as decubitus ulcers and ulcers due to poor blood circulation often appear in the elderly. [0003] Medical dressing is a material that covers wounds and assists wound healing. Cotton gauze is the largest medical dressing produced and used in my country. From the perspective of use, cotton gauze has a high liquid absorption capacity, which can evenly distribute the liquid in the entire gauze to prevent local accumulation of fluid. The organization of vitality brings great pain to the patient. With the aging of the social economy and the world popula...
