Description

Micro-positive pressure breathable protective clothing

Technical Field

The utility model belongs to medical treatment protective apparatus field, more specifically relates to a ventilative protective clothing of pressure-fired.

Background

Some microorganisms or viruses which are harmful to human beings greatly threaten human life through a highly destructive infection mode, namely respiratory tract/contact infection, and the microorganisms or viruses have strong adhesive force and penetrating power and have extremely high protection requirements under the condition that the characteristics and the roots of the microorganisms or viruses are not completely understood. However, the existing common protection methods have many disadvantages, for example, the protection method using a mask and common protective clothing has poor effect. The gaps around the mask are not tightly sealed, and the protection effect of the mask is linearly reduced due to long-time breathing when the mask is worn. By adopting the protection method, the air inhaled by people is not thoroughly filtered and disinfected, so that cross infection among doctor and patient groups is easy to occur. In addition, harmful microorganisms and viruses are filled in the air, and can be adsorbed on the surface layer of the common protective clothing, so that the medical staff still has the risk of infection when changing the clothing. Meanwhile, the existing medical protective clothing is disposable, and non-disposable protective clothing has no real-time disinfection function, so that medical staff are forced to wear the protective clothing for a long time and cannot be replaced randomly, and the economical efficiency and the comfort are greatly reduced.

CN1451450A discloses a multifunctional protective garment, which is characterized by a micro-positive pressure breathable protective garment. The protective clothing adopts an integral sealing design, and clean air is supplemented to the inside by a compressed air source, so that the protective clothing and the outside keep a certain positive pressure, and the protective performance is improved. However, the protective suit is not internally provided with an air distribution system, only supplies air to the head, and the comfort is still greatly influenced. CN1449697A discloses an epidemic situation protective clothing, which is provided with an airtight zipper and a transparent face mask, and is also provided with an air supply device and a power supply, wherein the air supply device is communicated with the protective clothing, thus avoiding the situation that the working efficiency is reduced due to the fact that the protective clothing is lack of fresh air, poor in circulation and uncomfortable to wear. However, after wearing the protective clothing, the wearer can have inconvenience in movement, and cannot bend down and sit down to rest on the wall, thereby limiting the movement of the wearer.
