Problems solved by technology

Including 1. Poor local blood supply: Wound repair requires rich blood supply, and insufficient tissue blood supply caused by various reasons will inevitably affect wound healing
2. Residual foreign matter: Foreign matter in the body will trigger the body's rejection reaction, making the wound tissue in the inflammatory reaction stage for a long time and affecting wound healing
[0007] The above factors are likely to increase the pain of patients and prolong the length of hospital stay, which will put a double burden on patients' thinking and economy.

Abstract

The invention provides a functional liquid dressing for hard-healing wounds. The functional liquid dressing is prepared from the following components of 10 to 175 of organosilicon quaternary ammoniumsalt, 15 to 85% of chitosan quaternary ammonium salt, 1 to 8% of allantoin, 1.2 to 3% of vitamin C, and 2 to 6% of calcium alginate, wherein the sum of the percentages of the solid raw materials is 100%. The functional liquid dressing has the advantages that the proportional ratio of the components is reasonable, the synergistic effect is realized, and the antibacterial, disinfection, bleeding-stopping, pain-relieving, anti-seepage, anti-sticking and healing-promoting functions are realized; the functions which cannot be realized by the traditional disinfection medicines and sanitary dressingscan be realized, and the obvious treatment effect is realized on the hard-healing wounds.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a functional liquid dressing for difficult-to-heal wounds and a preparation method thereof. Background technique [0002] Refractory wounds are also called refractory wounds and chronic wounds, but there is still a lack of a clear and unified definition. The International Society of Wound Healing defines it as a wound that cannot achieve complete anatomical and functional healing through a normal, orderly and timely repair process. Chronic non-healing wounds (ulcers) on the body surface refer to body surface wounds formed by various reasons, which fail to heal after more than 1 to 3 months (the time is not absolute) and have no tendency to heal. From the perspective of pathophysiology, the wounds that do not heal after a skin tissue defect cannot be repaired in a regular and orderly manner are called refractory wounds. Such patients are often secondary to other chroni...
