Studies have found that most viruses can directly or indirectly contact the human body through carriers such as patient body fluids, blood, droplets and other liquids, as well as particles suspended in aerosols. Close contact is more contagious. Therefore, when medical workers are in close contact with the source of infection, in addition to wearing protective clothing, they also need to wear medical masks independently at the same time. It is troublesome to put on and take off. In addition, when using medical protective clothing, the compatibility of the hood and the mask often causes the head to move. The neck is exposed to the external environment during the procedure. In view of the above-mentioned shortcomings of protective equipment, research on protective clothing in recent years has focused on the integrated design of the mouth, nose and head. CN215270777U discloses a disposable one-piece medical protective suit, which includes a protective suit body, a protective suit trouser part, and a protective suit hood.
