A kind of traditional Chinese medicine protective layer and its preparation method and application

Abstract

The invention belongs to the technical field of respiratory protection, and discloses a traditional Chinese medicine protective layer, which contains a traditional Chinese medicine composition. The traditional Chinese medicine composition is mainly prepared from the following components: ‑3 parts, Perrin 1‑3 parts, Artemisia argyi 3‑6 parts. The traditional Chinese medicine mask prepared by using the traditional Chinese medicine protective layer has good air permeability and wearing comfort; the aromatic smell produced by the contained traditional Chinese medicine composition can play a protective role of external drive and internal suction, and has a mechanical barrier with the mask. The combination of functions can effectively prevent respiratory diseases.

Description

technical field [0001] The invention belongs to the technical field of respiratory protection, in particular to a traditional Chinese medicine protective layer and its preparation method and application. Background technique [0002] Pollutants in the air and the various bacteria and viruses carried by them are not easy to block, and can easily invade the human respiratory tract through the mouth and nose, endangering human health. When necessary, people usually choose a mask as a protective device for the mouth and nose. Whether it is resisting PM2.5 particles or filtering bacteria and viruses, the important role of masks has been highlighted many times in life. [0003] With the improvement of people's awareness of protection in recent years, the use of masks has become more and more popular, and the types have become increasingly rich. The basic principle of its protection is mechanical barrier, which can isolate inhalable particles from intrusion (filtering) by increas...

Problems solved by technology

[0004] In order to prevent respiratory diseases caused by bacteria and viruses, the masks commonly used by the public include medical surgical masks and N95 masks. The advantages of medical surgical masks are that they have good air permeability and have a certain ability to filter bacteria and viruses, but their performance is not outstanding enough; while N95 masks refer to The type of mask that can filter 95% of fine particles (tested with 0.3μm sodium chloride particles, the barrier rate must reach more than 95%) has a good ability to block viruses, but its disadvantages are that it is too fine and tight. Causes great breathing resistance and greatly affects air permeability

Therefore, the wearer will feel that breathing is obstructed, causing obvious discomfort, and the wearing process may cause bacteria and viruses to breed on the inner surface of the mask, causing secondary pollution
