Nano silver calcium alginate antibacterial dressing

Abstract

The present invention relates to a nano silver calcium alginate antibacterial dressing. It is a product made up by using calcium alignate fibre on which the nano silve granules are adsorbed, the nano silver content is 0.01-1% of total weight of said dressing. Besides, said invention also provides its preparation method and concrete steps.

Description

technical field

[0001] The invention relates to a medical dressing for wound treatment, a nano-silver calcium alginate antibacterial dressing. Background technique

[0002] In the process of wound treatment, cotton gauze soaked in medicinal liquid is often used, applied on the wound or embedded in the wound, to stop bleeding, relieve pain, reduce inflammation, maintain a moist environment of the wound, and promote wound healing. Traditional cotton gauze absorbs less liquid, usually only 4 to 5 times its own weight.

[0003] The medical dressing made of calcium alginate fiber can perform ion exchange with the sodium ions in the wound exudate and blood, releasing calcium ions, which can accelerate the formation of blood clots in the capillary ends, and the hemostatic effect is particularly good; As the amount of absorbed sodium ions increases, calcium alginate gradually converts into water-soluble sodium alginate, forming a thin gel layer on the wound surface, thereby prevent...
