The sudden onset of the new coronary pneumonia epidemic has brought about a problem in the supply of medical supplies. Various automobile companies are also the use of manufacturing heritage have been mobilized, "cross-border" production masks, disinfectant and other medical supplies, as far as possible for the fight against the epidemic to contribute to the effort. However, with the masks, protective clothing and other medical supplies, with a "mobile large N95 mask" title of the negative pressure ambulance, but also in the overnight face a small gap.
To this end, on January 24, the Ministry of Industry and Information Technology issued the first batch of 200 negative pressure ambulances to the country's urgent production tasks, requiring part of the order on February 5 delivery. After receiving the task, BAIC Foton, Fujian Benz, Jiangling Group, Yutong Group, Brilliance Group, SAIC Datsun and other 12 domestic commercial vehicle enterprises acted quickly to support the war "epidemic" on the front line to start a rush to make negative pressure ambulance "time race". At present, most of the negative pressure ambulances have been successfully off the line and went to the front line of disaster relief, playing their due value.
What is the difference between a negative pressure ambulance and an ordinary ambulance?
In the face of a highly contagious new coronavirus infection pneumonia epidemic, the ordinary ambulance has appeared to be a little more than the ability to do, and this time a negative pressure device with a "negative pressure ambulance" is to solve the problem of the right way.
Negative pressure ambulance, as the name suggests, is through the negative pressure generator work, so that the pressure inside the car is always lower than the external atmospheric pressure. The working principle is similar to our home use of water purifier, tap water from the water pipe into the water purifier, out of the more clean and hygienic softened water. And this time the water purifier is equivalent to the negative pressure ambulance within the negative pressure device, the negative pressure device so that the air pressure inside the car is lower than the car outside the atmospheric pressure, so that the air can only be inflowed from outside the car to the car, and the inflow of air sterilized and discharged out of the car. And before the air inside the car is discharged, it will also be filtered by high-efficiency filtration (99.97%@0.3um) so that the discharged gas will not cause pollution of the environment outside the car.
Additionally, some negative pressure ambulances also have isolation compartments, which are another confined space, but with air inlet/outlet ports and negative pressure devices, so that the patient's breathing can be completely isolated from the rest of the occupants of the vehicle, avoiding the possibility of cross-infection, and further protecting the safety of more people's lives.
Besides the hardware differences, what else makes a negative pressure ambulance different?
The first and biggest difference is the price. Because the negative pressure ambulance increased negative pressure equipment and isolation chamber, even the relatively inexpensive Chinese brand, the offer is basically more than 300,000 yuan, compared with the same brand of ordinary ambulance at least 100,000 yuan more expensive.
Of course, the difference in price is not only due to the additional equipment. Negative pressure ambulance is able to realize negative pressure, the most basic premise is to ensure that the car is absolutely airtight, which is the car's assembly process and the level of materials has extremely stringent requirements, said it is the quality control requirements than the luxury brand passenger cars are also high is not too much.
Another major difference is the production process. Compared with traditional passenger cars that can be delivered to end-users off the line from the OEM, commercial vehicles, including ambulances, need to be customized on the basis of the base vehicle, such as negative pressure ambulances need to be modified through the foam insulation treatment, wiring, interior installation, electrical, medical equipment installation, negative pressure facilities installation and other steps, which makes the production cycle increase dramatically.
For example, on New Year's Eve, the company received an urgent assignment to deliver 60 negative-pressure ambulances within 10 days, which means that it can only produce an average of six ambulances per day. This may not seem like high efficiency, but it's actually the fastest speed after the factory worked overtime to reduce the production cycle by two-thirds, which makes the production of negative-pressure ambulances so difficult and complicated.
Car Conclusion
Disaster has no mercy, although the sudden epidemic let us seem a bit surprised, but the epidemic also let us feel the Chinese people unity, and dare to fight the courage of the disaster. More than a month has passed since the outbreak of the epidemic, but from this we can see the country's rapid response to emergencies, and feel what is called China's speed. We believe that in a short time, we will be able to take off our masks and walk on the streets to enjoy the warmth that spring brings us.
