What brings people to the hotel for isolation?

COVID-19 is a respiratory infectious disease, so the virus can spread through the respiratory tract, and the inside of the negative pressure car is completely isolated from the outside of the car, so people are pulled to the hotel by the negative pressure car for isolation.

However, the strength of negative pressure ambulance can not be underestimated, which has played a key role in the prevention and control of epidemic situation in Hebei, and also has the reputation of "mobile N95 mask" in the industry. I don't know if you have noticed a detail. Since the outbreak of the epidemic in Hebei, after the confirmed cases, the official will say that they will be transferred to the hospital with a "negative pressure ambulance".

As early as the SARS period in 2003, the ambulance with this negative pressure technology was developed and manufactured. In Wuhan at the beginning of 2020, the negative pressure ambulance once again shines brilliantly, successfully completing the task of transporting critically ill patients to "Raytheon Mountain" and "Vulcan Mountain", and also taking the lead in the recent epidemics in Hebei and Heilongjiang.

On the basis of ordinary ambulances, negative pressure ambulances need to be equipped with a negative pressure device and a negative pressure isolation cabin. The same space also needs to be equipped with a full set of rescue equipment such as ventilator, ECG monitor, ultraviolet disinfection lamp and oxygen supply interface. The function of ordinary ambulance, negative pressure ambulance has.

Negative pressure ambulance can not only transport patients, but also solve the infection problem. How to deal with cross-infection between patients and medical staff? Clever researchers have come up with a way to solve this problem perfectly as long as there is no loop in the airflow. Based on this theoretical model, the negative pressure device came into being.
