Hospital grade wound dressing, as the covering on the wound site, can replace the damaged skin and play a temporary barrier role.During wound healing, avoid or control wound infection and provide an environment conducive to wound healing.This paper makes a summary of the types, characteristics and functions of commonly used hospital grade wound dressing.             

According to the materials adopted, hospital grade wound dressing can be roughly divided into natural materials, synthetic polymer materials, inorganic materials and composite materials.

When in contact with wound exudate, carboxymethyl cellulose dressings form a gelatinous body that adheres well and keeps the wound moist.

It has the function of antibacterial, anti-inflammatory, hemostasis, reducing wound exudation and promoting wound tissue regeneration, repair and healing.

With a strong absorbent, the wound surface water gel, can not only provide moist environment for wound healing, and in the process of wound healing by biodegradation gradually in the drainage, there is no fiber residual wounds, when it come into contact with wound drainage through ion exchange generate soluble sodium alginate, replacement of the calcium ion surface can accelerate wound to stop the bleeding.
