Time has entered February, the outbreak of the new coronavirus pneumonia epidemic continues to spread, but the whole country up and down the city, the development of the epidemic has gradually presented a controllable situation, which, fighting on the front line of health care workers when the first credit. At the same time, various industries have also donated donations to support the front line of the fight against the epidemic, which, the automotive industry performance eye-catching.
Today, we are going to talk about the negative pressure ambulance that several automobile manufacturers have been working overtime to produce at this particular moment. What is the difference between this negative pressure ambulance and the ambulance we know everyday? Why is a negative-pressure ambulance needed for this outbreak?
What is a negative pressure ambulance?
Unlike the ambulance we know every day, the negative pressure in a negative pressure ambulance literally means that the air pressure inside the vehicle is negative compared to the outside, which is realized by the air extraction equipment installed on the vehicle. This is achieved through the installation of air extraction equipment on the vehicle, which is driven by an electric motor and changes air 20 times per hour, allowing the vehicle to realize a negative pressure value of -10Pa to -120Pa.
At the same time, working in tandem with the ventilation equipment, there is a virus inactivation device that can kill more than 99.97% of germs, thus preventing viruses inside the ambulance from being discharged outside the vehicle. If you think about it, the air pressure inside the car is negative, even if there is still air flow outside the door, windows, etc., but it is also from the outside of the car to the inside of the car flow, but also can completely avoid the leakage of the virus inside the car.
Generally speaking, inside a negative-pressure ambulance, outside air enters the vehicle from the top, and is then sterilized and filtered out by the rear of the vehicle. And the air flow direction of the vehicle is designed to be relatively fixed, that is, from the medical staff area to the patient area, and then from the bottom of the vehicle out of the vehicle. This ensures that the ambulance is a clean and sterile space, and there is no air circulation inside the vehicle, so there will be no cross-infection of the personnel inside the vehicle.
In addition, the negative pressure ambulance also has upgraded equipment available, that is, the negative pressure isolation chamber, which is based on the stretcher to increase the sealing and negative pressure device, for the process of transporting high patients to avoid the spread of viruses is more effective.
Why are negative-pressure ambulances important?
As mentioned above in the explanation of the principle of negative pressure ambulance, negative pressure ambulance can minimize the spread of viruses in the process of rescuing the movement of infectious patients, but also can effectively avoid when the medical staff and patients in the same ambulance when the cross-infection.
The negative-pressure ambulance clearly plays a key role in transporting patients, knowing that avoiding the spread of the virus in the crowd on the one hand, and protecting frontline healthcare workers on the other, are both crucial in the current fight against the epidemic.
Which car companies are rushing negative pressure ambulances?
From the current public information, there are a number of car companies are working overtime to produce negative pressure ambulances. If it is in the usual, this may be nothing, but on the one hand, most of the car companies into the Spring Festival holiday, the vast majority of workers have returned home, on the other hand, suffered an epidemic outbreak, from the safety and other aspects of the consideration, the workers returned home is also temporarily unable to return to the factory work in a timely manner, therefore, the car companies to find ways to scheduling arrangements, not only to realize the production of negative pressure ambulances, and to do to shorten the production cycle, so that the fastest possible to provide to the The first line of the epidemic of medical personnel to use.
Jiangling Ford
Jiangling Ford, the largest ambulance manufacturer in China, resumed work on the first day of the Lunar New Year, and rushed to produce more than 1,700 ambulances by compressing the working hours, among which 200 negative-pressure ambulances were modified by Ford Transit and divided into negative-pressure, disinfection, and observation compartments. The whole vehicle adopts the domestic leading medical vehicle modification technology, including rescue system, warning system, electrical system, negative pressure system, etc., which can be used to carry out pre-hospital resuscitation, transfer and guardianship of infectious patients.
Shangqi Daitong
Shangqi Daitong received the production task of 60 negative-pressure ambulances from the Ministry of Industry and Information Technology (MIIT) on January 24th. Like JLF, SAIC Datsun's technical backbone returned to work on the first day of the Lunar New Year and strived to shorten the 30-day work period to 10 days, delivering the first 60 negative-pressure ambulances on February 5 to support the anti-epidemic front.
The SAIC Datsun negative-pressure ambulances are based on the SAIC MAXUS?V80 modified with integrated washable interiors, a centralized oxygen supply system, an independent closed medical warehouse and other systems.
Beiqi Foton
The Ministry of Industry and Information Technology (MIIT) on Jan. 24 simultaneously issued a task of 25 negative pressure ambulances to Beiqi Foton, which will be modified on the basis of the Tuyano, Scenic G9 and Scenic G7.
In addition, there are Fujian Benz, Brilliance Group, Chery Ruifu, Nanjing Iveco, Yutong Bus and other car companies into the production of negative pressure ambulance task.
The epidemic is now, we fight side by side, in the same boat ****, for an early victory over the epidemic!
