Description
Technical Field
The invention relates to the field of virus transmission blocking, in particular to a non-contact face near-distance air supply and exhaust device for preventing new coronary pneumonia virus transmission.
Background
When the person is in the same air environment as the potential new coronary pneumonia patient, the virus can be transmitted by using suspended particles in the air as a carrier. Viruses can pollute air nearby through the air, particularly saliva with the viruses can be mixed with the air to form aerosol which floats in the air for a long time, medical care personnel in hospitals can protect themselves by wearing protective clothing, and ordinary people cannot be infected even if wearing the mask in public places.
The new corolla pneumovirus is airborne and produces fine droplets to infect people nearby when the patient breathes, speaks, coughs or sneezes. The infected person may be infected with aerosol formed by fine droplets and gas suspended in the air at home, work, store, vehicle or medical place, and even if wearing the mask, the infected person may inhale the air with virus from the aerosol with virus in the gap between the face and the mask (especially in the valley between the bridge of the nose and the lower eyelid) because the mask is not completely attached to the face. According to the analysis of the paper published by JAMA in south China hospital in Wuhan, the intra-hospital and inter-person transmission rate of the new coronary pneumonia is estimated to be 41%. Intraventricular convergent transmission has become the primary route for the transmission of new coronary pneumonia.
When patients suddenly increase and medical settings and equipment are insufficient, people often can only stay at home and isolated. But isolating them at home is entirely likely to infect their own family. The prior art does not have a device capable of providing fresh air at a short distance for healthy people, and the outbreak of family type and gathering type infection is difficult to avoid. Even under the environment with the traditional fresh air system, the infection of 9 people in Beijing reshending hospital of the new coronary pneumonia, the infection of 39 people in Tianjin Diwu department store, and the infection of 200 people on the postal wheel of Japan 'Diamond princess' are typical examples.
At present, there is no device capable of providing fresh air to a healthy person in a close range without contacting the face in an indoor space.
