technical field

The invention relates to the field of sanitary protection articles, in particular to a fully enclosed two-way ventilation and one-way moisture-removing medical protective isolation suit.

Background technique

Although the existing protective isolation clothing can basically solve the problem of isolation. However, the main problems include: 1. Isolation suits made of uniform standards cannot achieve two-way ventilation and one-way moisture removal, and the interior is sultry and uncomfortable when used for a long time. After a lot of sweating, it is easy to cause bacterial growth and rapid reproduction of pathogenic microorganisms; 2. The uniform standard protective clothing has windows on the face, and additional protective masks and goggles are required. For users who need to wear framed eyes, it is easy to cause physical obstruction and affect vision; additional masks are also required. The skin between the mask/goggles and the protective clothing is still exposed, which is easy to cause the attachment of pathogenic microorganisms; 3. For the wearer of the isolation clothing made of uniform standards, the air quality of the local area of the oral cavity is affected by the air inside the entire isolation clothing, which cannot be Normal and smooth breathing of fresh air cannot keep the environment inside the isolation suit fresh; 4. The uniform standard protective isolation suit takes a long time to wear once. The ventilation effect is greatly reduced.
