Please remember that this expensive mobile "protective mask" has contributed a lot to the epidemic.

Pneumonia in novel coronavirus has attracted the attention of all walks of life, so serious that the older generation who never wear masks consciously wear masks, refuse to visit relatives and friends during the Spring Festival and wait for the epidemic to end at home.

While everyone is waiting at home in response to the call, some enterprises and people have chosen "retrograde" and produced a large number of protective masks and other materials for hospitals in epidemic areas, so that we can see the human brilliance of "one party is in trouble and all parties support" in the ruthlessness of the virus, bringing some warmth to people and patients in epidemic areas who are still in the cold winter.

"20 19- novel coronavirus" is like a rampaging robber who enters the body through mucous membranes and gradually enters various organs and tissues in the human body, destroying everything; What is even more incredible is that even a gust of wind can bring the virus to yourself, which is especially obvious around infected people. The hospital also has protective equipment and disinfection and environmental protection, but it is really dangerous during transportation. At this time, it is necessary to have a huge "protective mask" on the stage, which is the negative pressure ambulance.

National Health Commission's latest "Work Plan for the Transfer of Pneumonia Cases in novel coronavirus (Trial)" clearly stipulates that negative pressure ambulances should be used as far as possible for the transfer of pneumonia cases in novel coronavirus.

What is negative pressure? It means using technical means to make the air pressure inside the car lower than the outside atmospheric pressure, which is equivalent to an isolation cabin. When the air flows freely, it can only flow from the outside to the inside of the car, and the negative pressure can also discharge the air inside the car after harmless treatment. In absolute isolation, doctors and patients can enjoy cleaner air, avoid more people being infected, and try to reduce the probability of cross-infection of more people when treating and transporting special diseases such as infectious diseases. This is one of the key materials needed to fight the epidemic.

Ambulance is equipped with a complete set of rescue equipment such as bio-safety negative pressure isolation stretcher, ventilator, defibrillator, ECG monitor, ultraviolet disinfection lamp, central oxygen supply interface, etc. , fully protect every link of the epidemic prevention front line.

Take Jiangling Negative Pressure Ambulance as an example, it can take 20 breaths per hour, the negative pressure value is stably controlled between-10Pa and -38Pa, and the filtration separation rate reaches 99.9%, so that people inside and outside the ambulance can get the highest protection, which is equivalent to an expensive "protective mask".

Why did Bian Xiao say that? Just look at Jean Merieult's BSL-4 laboratory, which is the most advanced high-risk virus laboratory in the world (the P4 laboratory in Wuhan was also built in this way). Some people call BSL-4 laboratory "devil's laboratory", not only because it contains viruses that can destroy the world, but also because its air conditioning system is as powerful as the devil.

You should know that the temperature and humidity of the air entering the laboratory are preset, and the filtration rate reaches 99.999%, which can ensure that the air circulates in the whole environment for one hour many times. The directional negative pressure reaches -40 Pa, so that the air in the laboratory can only come in from the outside through the high efficiency filter, and the air in the laboratory cannot flow out. Scientific researchers need to go through layers of disinfection and investigation when they enter and leave the laboratory, and the probability that the virus is left behind is almost zero, which is why history categorically says that the virus is not left behind in the laboratory.

Knowing the strength of Jean-Merieult BSL-4 laboratory, do you know the strength of negative pressure ambulance? Its role in the epidemic is undoubtedly enormous. I also hope that the country can develop specific drugs as soon as possible to save more lives.
