From the end of last year Wuhan new pneumonia has been spreading, the whole country is filled with a tense atmosphere, in the fight to prevent and control the new coronavirus epidemic war. As a medical staff, for various reasons did not go to the front line, but is often the middle of the night tossing and turning can not sleep, can only be in the heart of the silent for Wuhan, for China to cheer! And almost every moment to keep an eye on the epidemic, especially concerned about the situation of medical supplies in Wuhan, in the knowledge that SAIC MAXUS emergency production of 60 negative pressure ambulance reinforcement in Wuhan, the heart doubly happy, but see a hot search comments many many on the negative pressure ambulance wrong understanding, as a hospital working for decades of semi-professional car enthusiasts, can not help but want to talk to you about this negative pressure ambulance.
First of all, what is a negative pressure ambulance, negative pressure ambulance, can also be called protective ambulance, mainly used for major infectious disease safety isolation and transportation. The difference with ordinary ambulance? In fact, the negative pressure ambulance from the appearance and ordinary emergency vehicles are not very different, but the biggest difference with the ordinary ambulance is to realize the "negative pressure isolation". In fact, we can understand the negative pressure ambulance as a normal ambulance with a "mask", so that the car and the car can be completely "isolated", but at the same time, the price of negative pressure ambulance is also much higher. And like our hospital, the number of ordinary ambulances is far more than the negative pressure ambulance, this kind of special ambulance is specially designed to deal with the situation like this epidemic or sudden outbreak of infectious diseases.
Why did you need a negative-pressure ambulance for this outbreak? This is from the new coronavirus transmission mode, from the droplet transmission, the new coronavirus has the characteristics of airborne transmission, the patient in the ambulance transportation, transfer process, there is a virus leakage of the hidden danger, once the virus leakage, it will let more people exposed to danger, increase the risk of infection. Therefore, the ordinary ambulance used to transport non-infectious diseases is not suitable, so it is necessary to use a special customized negative pressure ambulance.
How does the SAIC MAXUS V80 negative pressure ambulance work? As I said before, the key to the negative pressure ambulance is "negative pressure", from the name can also be seen, negative pressure, that is, the patient cabin inside the car is less than the cockpit and the car outside the atmospheric pressure, the air outside the car can be free to run to the car, but the air inside the car will not "themselves" to run to the outside.
Simply put, the air into the negative pressure cabin is fresh, and no circulating air, so that the source of disease in the cabin "nowhere to hide", like a "sterile room". So in the negative pressure ambulance treatment and transfer of infectious diseases and other special diseases, can minimize the chance of cross-infection between medical staff and patients, but also to avoid more people infected, to achieve the real "safe isolation".
To put it simply, in fact, the production process of negative pressure ambulance is very strict and complex. Like this V80 negative pressure ambulance medical cabin and cab can be effectively isolated, the use of vehicle telephone communication. Negative pressure generator work, can control the direction of air flow in the car, so that the medical cabin air to form a directional flow, medical cabin and the external environment to form a relative low pressure difference in the atmosphere (relative pressure between -30pa to -20pa), so that bacteria will not be spread through the car to the outside air. The negative pressure system has: large exhaust air volume (400m3/h); the use of advanced full closed-loop PWM speed control to ensure stable pressure control in the medical compartment.
Will it pollute the surrounding air? Of course not. According to the design requirements, the air discharged from the sick bay goes through a high-efficiency filter, which can 99.97% filter bacteria or fine dust above 0.3 micron. However, the average diameter of the new coronavirus in this case is about 0.1 microns, 0.3 microns can not prevent ah? So here, but also need to "exhaust air purification device" to help, exhaust air purification device integrated power exhaust, high efficiency air filtration, ultraviolet sterilization / poison, negative pressure monitoring and alarm functions in one. It can filter and kill bacteria or viruses in the air to ensure that the air discharged from the negative pressure ambulance is free from virus pollution. Classification of negative pressure ambulance models? In terms of models, I learned about SAIC MAXUS?s V80, he has a special medical platform ambulance series, also according to the actual use is divided into a short medium, long medium, long and high negative pressure monitoring ambulance, and according to the single and double sliding door is divided into six models. This support Wuhan negative pressure ambulance for the long axis in the top model, online to find two pictures to show you.

Overall, the negative pressure ambulance has become the guardian angel of the health care workers when transporting the infected patients in this epidemic, and the maximum protection of the health care workers is a great contribution to the fight against the epidemic at any time, so the importance of the negative pressure ambulance is self-evident. Finally, I also want to praise for the production and modification of negative pressure ambulance car companies, in the new coronavirus ravaged the moment, they use the actual action to let us witness what is a party in trouble, eight parties to support, what is the unity of purpose, **** overcome the difficulties.
This time to see the Datsun ambulance support Wuhan thing, and the epidemic around a lot of V80 owners spontaneous for the epidemic staff to shield the wind and rain, I really very moved. Not because our hospital is also configured V80 ambulance, but in the country and compatriots have difficulties, our state-owned car companies and owners can unite as one, so responsible, maximum fulfillment of their social responsibility, the moment of crisis, the most can see the glory of human nature, I believe that in the efforts of all the motherland will be able to get through the crisis, and hope that far away from Wuhan, my colleagues, teachers and students can come back safely. The company's website has been updated with the latest information about the company's website and its website.
The Spring Festival of 2020 is indeed a bit difficult, the new coronavirus has touched the hearts of all people, ordinary people are afraid, while fighting in the front line of the white angels, they are exceptionally calm and determined, they are our "guardian angel", and I hope that our car companies to go to support the "large masks" can become a part of the "guardian god", and I hope that our car companies to go to support the "large masks" can become a part of the "guardian god". Large masks" can become these lovely angels "patron saint", leading all the people together to fight and return in triumph! Let us firmly believe that after endless darkness will eventually usher in the dawn, life will still be like flowers blossom.
