Abstract

Abstract:

In order to improve the structural design of medical protective clothing, broaden the source of materials and improve its protective functions, this paper reviewed and analyzed the structures and functions of medical protective clothing at home and abroad. In terms of selecting materials for medical protective clothing presently available, five types of commonly used fabrics were compared in advantages and disadvantages, and the analysis shows that the polytetrafluoroethylene composite fabric meets the protection requirements, while the comfort is the best among all. By comparing the standards of medical protective clothing among China, the United States and the European Union, it is found that the liquid barrier is the main factor affecting its protective functions. This paper summarized the main brands of medical protective clothing in the world, and points out that the medical protective clothing should meet the requirements of middle finger ring design, self-adhesive zipper placket and adhesive tape close edge seam. Finally, in view of the urgent problems of medical protective clothing, the future development direction of medical protective clothing was prospected from three aspects including country, technology and protective clothing itself.

Key words: medical protective clothing, structure design, protection function, protective standard, evaluation index
