Negative pressure ambulance, an expensive “mask” in the fight against the epidemic

As the novel coronavirus pneumonia epidemic continues to spread, the lives of each of us have also changed. With extended holidays, traffic restrictions, online working, etc., it can be said that not running around is contributing to the fight against the epidemic. In this extraordinary period, there is one type of vehicle that must move forward bravely, racing against time, and you can see it wherever the danger is most, and that is the ambulance.

I remember that during the SARS outbreak, when I was still young, I would feel a little nervous whenever I heard the sound of an ambulance on the road. Although I admired the medical workers on the ambulance who were fighting on the front line, I still felt a little nervous. Ambulances will also be kept away during an epidemic. Although the new coronavirus is more severe than SARS this time, we, who have matured, have shown great determination in facing the epidemic, and all walks of life have also shown love and support to Wuhan and Hubei as a whole. Among them, as an automobile editor, I noticed that among the assistance from automobile companies, those models that escort medical workers and infected people-negative pressure ambulances.

What is a negative pressure ambulance?

Negative pressure ambulances, also called protective ambulances, are different from ordinary ambulances. The biggest feature of negative pressure ambulances is that they can be "negative pressure isolated." Similar to the negative pressure ward in the intensive care units of major hospitals today, it is used for the safe isolation and transportation of infected people when an infectious epidemic breaks out, and can effectively protect medical workers and the external environment from contamination and prevent The epidemic spread further.

The working principle of negative pressure ambulance

In addition to the professional rescue equipment of ordinary ambulances, negative pressure ambulances can also ensure the safety and hygiene of the medical cabin, and are isolation and anti-corrosion sex, ventilation and bacteria resistance. Through the negative pressure device in the car, the air pressure in the car is lower than the outside atmospheric pressure. When the air is allowed to flow freely, it can only flow from outside the car to the inside of the car, and the air in the car is discharged after harmless treatment. Create a fixed air circulation area in the negative pressure cabin. The air flows from the clean area (medical staff area) to the infection source area (patient area), and the air pressure in the cabin is maintained between -10Pa and -120Pa to minimize the dead corners and vortex flow of the air flow. It also allows clean air to enter the car from above and be discharged from under the car, so as to ensure that the head position of the medical staff is free of contamination as much as possible. The polluted air below is converted into sterile air through the exhaust and filter devices and discharged outside the vehicle. Ensure the safe isolation of medical staff and the outside world during transportation of patients.

Negative pressure ambulance manufacturers that support the epidemic

1. Jiangling Ford

In the news we can see some of the key points of Wuhan more than once This JMC Ford Transit ambulance is used in all treatment hospitals. At present, Jiangling Ford has received orders for 1,000 ambulances, including 200 Transit negative pressure ambulances. Jiangling Ford has also set up an emergency response team and started production and transportation during the Spring Festival holiday to ensure that Transit negative pressure ambulances can be delivered quickly. Arrive at the front line and start working.

JMC Ford is also the brand with the largest number in this support team. Based on 200 negative pressure ambulances and 800 ordinary ambulances, the cost of naked vehicles without medical equipment is approximately 140 million yuan

2.?SAIC Maxus

The Ministry of Industry and Information Technology assigned SAIC Maxus Automobile Co., Ltd. to produce 60 negative pressure ambulances during the Spring Festival holiday, and it was coordinated by the Shanghai Economic and Information Technology Commission Finish. This ambulance is based on the SAIC Maxus V80. The price of 60 vehicles does not include medical equipment, which is about 9 million.

3. Fujian Benz

After receiving the notice from the "Material Support Team of the National Joint Prevention and Control Working Mechanism to Respond to the Novel Coronavirus Pneumonia Epidemic", Fujian Benz urgently completed the delivery of 20 vehicles The production of Fujian Mercedes-Benz Vito negative pressure ambulances was urgently sent to the epidemic areas overnight, involving a total amount of approximately 8 million yuan.

4. Brilliance Group

Brilliance Group also received production instructions from the Ministry of Industry and Information Technology and worked overtime to complete the production of 30 Jinbei G16 negative pressure ambulances. The cost involved is about 3 million.

5. Beiqi Foton

Beiqi Foton is also one of the companies supporting the epidemic. The Ministry of Industry and Information Technology has assigned it the production task of 25 negative pressure ambulances. The model is Tuano. , Scenery G9 and Scenery G7 were coordinated and completed by the Beijing Municipal Bureau of Economy and Information Technology. The cost involved is estimated to be 3 million.

It can be seen that domestic ambulances are basically manufactured by our domestic companies that produce commercial vehicles, and are modified based on mass-produced vehicles. Therefore, compared with ordinary car companies that donate money and materials, ambulances are powerful weapons that can directly fight on the front line, and they are also "expensive masks" to protect us. I would also like to thank all the major car companies for their contribution to this epidemic. I believe that with our concerted efforts, we can win this war without smoke as soon as possible.
