Physical bacteria and stick resistant dressing for medical purpose

Abstract

The invention relates to a physical antibiotic antiseizing medical dressing through sewing five functional layers, the first layer is an antibiotic antiseizing layer, the second layer is a hydrophilic layer made of hydrophilic nonwoven fabrics, the third layer is a macromolecular absorption layer, the fourth layer is an auxiliary layer, the outmost layer is a hydrophobic layer.

Description

technical field

[0001] The present invention relates to materials for medical care, in particular to medical dressings with antibacterial, anti-adhesive, hydrophilic and hydrophobic functions. Background technique

[0002] Wound healing is the prerequisite for the recovery of body function after trauma, so the research on accelerating wound healing is particularly important. Among them, the development of wound dressings is one of the hot spots in medical research in recent years. Traditional wound care mainly uses degreasing gauze as the material, which is impregnated in disinfection and sterilization drugs to achieve antibacterial effect. However, due to the adhesion of the gauze to the wound, the chemical drugs also have side effects such as irritation and allergy to the wound in varying degrees, so that the wound is repeatedly damaged and damaged, and cannot be healed for a long time, and even secondary infection. At present, medical dressings mainly use vaseline gauze,...
