Problems solved by technology

The commonly used clinical dressings are mainly made of gauze, medical degreasing and other materials. Although the cost is low, the source of raw materials is wide, the production is simple, and it has strong absorption capacity, but the hemostatic effect is not good, and the non-wound surface moisturizing effect is easy to cause secondary damage. The effusion is prone to bacterial infection, etc.

Abstract

The invention provides a dressing prepared from nanometer silver and far-infrared ceramic micro-powder and a preparation method thereof. The dressing is prepared from a nanometer silver composite antibacterial layer and a spongy fabric layer. The nanometer silver composite antibacterial layer comprises 90-95wt% of polyethylene glycol 4000 and the balance nanometer silver particles. The nanometer silver particle has the particle size D90 of 15nm. The spongy fabric layer is prepared from far-infrared ceramic powder and a polymer of polyethylene glycol 6000 by mixing. The mixture comprises 70-80wt% of the polyethylene glycol 6000. The dressing has good antibacterial properties and good healing effects and can be prepared simply.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, in particular to a dressing made of nano-silver and far-infrared ceramic powder and a preparation method thereof. Background technique [0002] Skin trauma is a common disease. In order to avoid the influence of bacterial infection and other external factors, protect and promote wound healing, various wounds and wound surfaces are often temporarily covered with medical dressings. The commonly used clinical dressings are mainly made of gauze, medical degreasing and other materials. Although the cost is low, the source of raw materials is wide, the production is simple, and it has strong absorption capacity, but the hemostatic effect is not good, and the non-wound surface moisturizing effect is easy to cause secondary damage. The effusion is easy to cause bacterial infection and so on. [0003] Nano-silver, as a new type of nano-medical material, is widely used in the field of antibacter...
