The main production processes include melt-blown, spunbonded, hot air or needling, etc. They have the effects of resisting liquids, filtering particulate matter and bacteria, etc., and are a kind of medical protective textile.

[0003] In the existing patent, a new type of N95 mask, the patent authorization number CN215387112U not only has excellent filtering performance, but also can realize the drinking function without removing the mask during the use of the mask, and the functionality and practicability of the mask are strong.

[0004] However, in the patent authorization number CN215387112U, external air enters the lid through the through holes on the lid, and after being filtered by the N95 filter cotton and the activated carbon layer, it enters the mask. The cold flow breathing valve closes when inhaling and opens when exhaling, quickly discharging the hot and humid air. Since the filtering structure inside the inhalation component needs to be replaced regularly after use, and since the filtering structure is located inside the inhalation component, tools are required to take out the filtering structure from the inside of the inhalation component during replacement, which is inconvenient for replacement. Therefore, we propose a protective device for medical staff in the respiratory department. Content of the Utility Model
