An outbreak of pneumonia due to a new coronavirus infection occurred in Wuhan, Hubei Province and other areas, and quickly spread to all parts of the country and some overseas countries and regions. As Wuhan is the birthplace of the epidemic and the hardest-hit area, there is a serious shortage of supplies, which has touched the hearts of countless people. As a result, all sectors of society have been lending a helping hand, whether in terms of money or relief supplies, and everyone is doing what they can to help Wuhan get through this as soon as possible.
Not only basic supplies such as masks and protective clothing, but ambulances have also become one of the very important supplies. However, due to the special transmission route of the new coronavirus, the general ambulance is unable to perform, and then the negative pressure ambulance is needed. Therefore, SAIC, Foton and so on several domestic responsible for the production of negative pressure ambulance car companies to give up the Spring Festival holiday, overtime production, for the fight against the condition of the race against the clock, first of all, to them to pay tribute.
What exactly is a negative pressure ambulance? Before we talk about that, we first need to understand the particular transmission pathways of the new coronavirus and why ambulances in general can't have a limited role in this outbreak.
New coronavirus
On January 28, the National Health Commission released the "Pneumonia Treatment Program for New Coronavirus Infections (Fourth Edition)," which shows that the new coronavirus is transmitted by respiratory droplet transmission is the main means of transmission, and can also be transmitted through contact. Due to the special nature of droplet transmission, the general ambulance can not be completely sealed, in the process of transporting patients may be virus leakage, so in the current special period, we need a special ambulance, that is, negative pressure ambulance.
At present, ambulances in most cities don't come with negative pressure function, and most of common diseases don't need this special function, so the reserve of hospitals in major cities is not enough, so in the world, negative pressure ambulance is a special model.
What is a negative pressure ambulance?
Literally, the air pressure inside the vehicle is negative. As we mentioned earlier, a typical ambulance may have a virus leak during transportation. Imagine if someone is smoking inside the car, we usually put the sunroof up, so the air flow rate on the roof is higher than inside the car, creating a negative air pressure, and the smell of smoke inside the car will be "pumped out" of the car, which is just like a normal ambulance where viruses can leak out.
But the negative pressure ambulance will not appear such a situation. Negative pressure ambulance will be placed in an air extraction equipment, through the power drive, so that the air pressure inside the car is always lower than the outside atmosphere, 20 times per hour, the negative pressure value of -10Pa to -38Pa between. At the same time, there will be inactivation device (disinfection equipment) and other core components after the extraction equipment, disinfection equipment can kill more than 99.97% of the germs, to avoid contamination of the gas discharged outside the car environment. At the same time the car can also be optional isolation cabin, isolation cabin in the stretcher on the basis of the increase in sealing, negative pressure device for isolation and transportation.
Motorists in action
January 28, as the largest domestic ambulance production enterprises, Jiangling Motors Co., Ltd. donated 10 Ford Transit negative-pressure guardianship ambulances to Wuhan. It is understood that this donation to Wuhan Ford Transit negative pressure monitoring ambulance of the first generation of models, it is the previous fight against SARS when the development of Ford Transit ambulance special vehicles, in that year belongs to the country's first, and in the process of epidemic prevention and control at the time played a positive role. This morning, JLM stepped up the production of 18 Ford Transit negative pressure ambulances sent to Wuhan, emergency aid.
Compared to the Jiangling Ford Transit, Brilliance production of special vehicles Jinbei G16 high-roof luxury ambulance is based on the Renault Jinbei Gurrys chassis to build. Inside the car using self-sterilizing composite materials, soft package material is used antibacterial PU, with easy to clean, can be sterilized and other characteristics. In addition, the "one-arm" design ensures that commonly used consumables and medical equipment are within one arm's length, improving the efficiency of rescue.
In addition to Jiangling and Brilliance, SAIC MAXUS also received an urgent task on New Year's Eve, requiring the delivery of 60 negative-pressure ambulances before February 5th. Under normal circumstances, the production cycle of negative pressure ambulances is about 20-30 days. Negative pressure ambulance based on SAIC MAXUS?V80 modified with integrated washable interior, central oxygen supply system, independent closed medical warehouse and other systems to protect the clean air inside the car, the car virus does not leak.
Beijing Automobile Foton also released a statement on January 27, will be actively involved in supporting the epidemic prevention and control work, seize the organization of the production of negative pressure ambulances, previously, Beiqi Foton has expedited the production of 25 negative pressure ambulances, which have been put into use. At the same time, BAIC Foton also participated in the construction of Wuhan Vulcan Mountain Hospital, coordinating all the local Ouman dump trucks and Raisa pump trucks in Wuhan, and finally the hospital was successfully completed.
Chery Holdings Group under the Chery Ruifu Special Vehicle Technology Co., Ltd. also took the initiative to "war", overtime to rush production of 20 sets of negative pressure ambulance, as of February 1, has been offline 12, 20 negative pressure ambulance is expected to be formally delivered on February 5th. In addition, Yutong Auto also donated 10 sets of negative pressure ambulances for the fight against the epidemic.
Finally
The negative pressure ambulance, as a "mobile rescue room" for preventing and controlling the spread of the epidemic and rescuing patients, is one of the important components in the fight against the new coronavirus. In the face of the epidemic, we saw the front-line workers to fight the epidemic, the spirit of sacrificing one's family for the sake of everyone. Although we are not on the front line, we should also actively cooperate, and personal protection should not be slackened even more. We should wash our hands frequently, wear masks, and go out less often. Protecting ourselves means protecting others. Finally, I would like to pay tribute again to the workers from all walks of life who are fighting against the new coronavirus pneumonia.
