The year 2020 is destined to be an extraordinary year, I believe that this year's coronavirus outbreak event may be one of the things that we will be hard to forget in this life, and in the unseen war, the negative-pressure ambulance assumes an important role.
Everyone has seen ambulances whizzing by while driving on the road, but we all seem to lack an understanding of ambulances and have only seen some of the scenes in ambulances in clips from movies. In the case of this coronavirus outbreak, there is a special kind of ambulance that plays an incredibly important role: the negative pressure ambulance.
In this war against the virus, many light bus manufacturers, such as SAIC Datsun, Fujian Benz, Foton, Jiangling Ford, Yutong Bus, etc., have been given an important and urgent task, which is the production of negative-pressure ambulances, and the reasons why so many negative-pressure ambulances have to be produced urgently also start from the spread of the coronary virus.
In January 28 of this year, the National Health Commission released the "new coronavirus infection of pneumonia diagnosis and treatment program" shows that the human respiratory droplets are the main means of transmission of the virus, so in the patient transferred to the hospital through the ambulance in the figure, there is a respiratory droplets, outside the person once contacted will have the risk of infection. Therefore, in the transfer of patients on the way also need so a confined space to isolate the outside world, which requires the use of negative pressure ambulance.
Of course, most of the ambulances we see on the road are not negative-pressure ambulances, because the manufacturing cost of negative-pressure ambulances is very expensive, and negative-pressure ambulances around the world belong to a special medical equipment, its negative pressure equipment is also mainly aimed at those who have a special infectious diseases, why negative-pressure ambulances can isolate infectious diseases? Please continue to read.
Negative pressure, as the name implies, refers to the current atmospheric pressure is lower than the standard atmospheric pressure outside, when the space is in negative pressure, the air can only be from the outside of the space in the atmospheric pressure under the action of the flow into the space. Perhaps so that some physics is not very good students are more difficult to understand, then a small example of life.
When we drive, if there is a smoking passenger in the car, we usually open the sunroof at the end of the sunroof, up a little bit, in order to let the smoke from the car is pumped to the outside of the car? At this point, the air flow at the top of the car accelerated, resulting in a lower air pressure on the roof of the car to produce a negative pressure zone, and at this time, the atmospheric pressure inside the car is greater, so the air will be smoke out of the car.
Ordinary environment a standard atmospheric pressure value is 101.325kPa, negative pressure ambulance is the purpose of the vehicle's atmospheric pressure is lower than the standard atmospheric pressure to become a negative pressure, the general negative pressure ambulance air pressure will be lower than the standard atmospheric pressure of 10Pa ~ 38Pa.
Want to do the car for the negative pressure also need to have professional equipment for support, negative pressure Negative pressure equipment in the ambulance is like our home hood, driven by electricity can be the air inside the car constantly pumped away from the air with viruses for the pumping away of the air will also be filtered through the high-efficiency filters as well as inactivation of the device to inactivate the filtration and separation rate of 99.9%, so that the air discharged to the outside of the car into a harmless gas.
Of course, the negative pressure ambulance in addition to the negative pressure device, the car is also equipped with a respirator, defibrillator, cardiac monitor and other full set of rescue equipment, the installation of ultraviolet disinfection lamps, the center of the oxygen interface, etc., traumatic suture surgery and cardiopulmonary resuscitation and other salvation can be carried out in the ambulance, which is difficult to imagine in the ordinary ambulance. Such a powerful "mask" natural price is not expensive, a high configuration of the negative pressure ambulance price of about 500,000 yuan.
In order to cope with the epidemic, at present, BAIC Foton, SAIC Datsun, Brilliance Group and Jiangling Motors have received the Ministry of Industry and Information Technology under the production of negative-pressure ambulance orders, of which BAIC Foton 25, SAIC Datsun 60, Brilliance Automobile 30. In addition, Jiangling Ford has received an order for 1,000 ambulances, including an order for 200 Ford Transit negative pressure ambulances. At present, all the above car companies have ended their vacations in advance and are fully producing the required models. At the same time, Fujian Benz 20 Vito negative pressure ambulance base car completed out of the warehouse, has been sent to Beijing and Zhejiang, the above ambulances amounted to a total of about 200 million yuan.
In the face of the epidemic, at this time the negative pressure ambulance can be more precious than those expensive sports cars, because in the race to save lives and time, the negative pressure ambulance is our most reliable guardian.
