Abstract
Description
technical field
[0001] The invention relates to the field of medicine, in particular to a hydroxypropyl-β-cyclodextrin hemostatic gauze and a preparation method thereof. Background technique
[0002] With the continuous progress of medical technology, new medical materials and related technologies have been well developed. Among them, the development and improvement of hemostatic materials are beneficial to improve the problems of bleeding and bleeding during surgery, which is of great significance and has become a hot research topic in the field of medicine. Traditional hemostatic gauze is generally made of cotton, linen, etc., which has problems such as poor antibacterial and bacteriostatic ability, gauze fibers easily lead to foreign body rejection, affecting wound healing, and easy adhesion to wound tissue during use, causing secondary damage. The generated waste has a complicated treatment process and is easy to pollute the environment.
