According to the three-level protective hood, the two arms of a user are arranged in the first sleeve and the second sleeve in a penetrating mode, then thehood body is fixed, rotation of the hood and movement of the hood in the hood detaching direction are limited, and wearing and using of the hood are simplified.

Description

technical field [0001] The invention belongs to the technical field of protective headgear, in particular to a three-stage protective headgear. Background technique [0002] Virus transmission routes include contact transmission, droplet transmission, droplet air transmission, etc. Medical staff need to be equipped with corresponding protective equipment to deal with viruses in different transmission routes. For personnel with highly contagious viruses (such as the new coronavirus) that can cause aerosol operations, a third-level protection is required on the basis of the second-level protection. The third-level protection measures include wearing a headgear, the lower part of the headgear is provided with an opening, and one side is provided with a transparent window corresponding to the face. When in use, the headgear can be put on the head through the opening, the lower end of the headgear is lower than the shoulder, and the headgear can cover the user's head. In use, t...

Problems solved by technology

In use, the current headgear is prone to rotation, which makes the transparent window deviate from the user's face, and the user needs to adjust its angle frequently; due to the large opening of the headgear, when the user's head moves, the headgear tends to tend to the direction of headgear removal. Moving requires the user to continuously pull the headgear back to its original position. Therefore, the current headgear needs to be adjusted repeatedly during use, and the operation is cumbersome, which brings inconvenience to the normal development of other tasks for the user.
