Technical Field
The utility model relates to a protective clothing, in particular to a positive pressure protective clothing with the powerful isolation function of virus and bacteria.
Background
The protective clothing has wide application in the fields of heat insulation, flame retardance, bulletproof, static resistance, dust resistance, radiation protection, virus isolation and the like in the industries of fire fighting, military industry, chemical engineering, medical treatment and the like. When the common protective clothing is used, other protective articles such as a protective helmet, a protective mask and the like need to be used at the same time. The split protective clothing has poor protective effect at the gaps among different protective tools, and has the risk of protective failure. The integrated protective clothing usually needs to carry an oxygen bottle or connect an oxygen generator with a gas pipe to provide oxygen inside the protective clothing. The oxygen supply device is heavy, and the user can consume a large amount of energy when wearing the integrated protective clothing. The volume of the oxygen cylinder and the length of the gas transmission pipe limit the working environment range and the working time of the user. Meanwhile, the complicated oxygen therapy device becomes a potential safety hazard in a complicated working environment. In addition, in order to achieve the protection effect, the integrated protective clothing is usually worn in a fully-closed manner, and the problems of overhigh internal temperature, unsmooth breathing of a user and the like are easily caused in the using process. In addition, the common protective clothing and the integrated protective clothing are volatile in the damaged state, and threaten the health and safety of users.
