Abstract

The invention belongs to the field of medical materials, and particularly relates to an anti-adhesion healing-promoting antibacterial hydrocolloid dressing and a preparation method thereof. The anti-adhesion healing-promoting antibacterial hydrocolloid dressing comprises a back lining layer, an anti-adhesion layer and an elastic hydrocolloid functional layer, wherein the elastic hydrocolloid functional layer comprises a functional component and a base material, the base material is mesh-like polyester fiber, and the functional component comprises the following materials: an SEBS thermoplasticelastomer, liquid paraffin, vaseline, lanolin, sodium carboxymethylcellulose, a chitosan quaternary ammonium salt, and an antibacterial clathrate. According to the present invention, the hydrocolloiddressing can absorb the wound exudate and maintain the wet wound healing environment, cannot be adhered to the wound, and further has advantages of good antibacterial and healing-promoting effect andstrong practicability.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to an anti-adhesion and healing-promoting antibacterial hydrocolloid dressing and a preparation method thereof. Background technique [0002] In people's daily life, burns and scalds often occur, resulting in wounds of various depths, and are very easy to cause infection and various complications. Therefore, the development of medical dressings has gradually become a research hotspot. [0003] With the advancement of science and technology, there are more and more new wound dressings. Hydrocolloid dressing is one of the most commonly used advanced dressings. Because of its unique advantages, it is widely used in the treatment and care of various wound types, such as diabetic foot ulcers, various pressure sores, chronic infection wounds, etc., and has achieved great results. good clinical care. However, ordinary hydrocolloid dressings also have some technical problems that need to ...
