In front of tens of millions of "supervisors" across the country, two hospitals are being built in Wuhan - Vulcan Mountain Hospital and Thunder Mountain Hospital - and will soon be put into operation on Feb. 3rd and Feb. 6th. Upon completion of the two hospitals, more than 2,000 patients are expected to be transferred from their original medical facilities.
The transfer of patients with the new type of pneumonia cannot be done without the assistance of negative pressure ambulances. And it is during the prevention and control of this new coronavirus outbreak that such a new term has come into view. How is this ambulance different from ordinary ambulances? Why has it become a necessary material to deal with the epidemic?

What is negative pressure ambulance?
As the most expensive masks to protect your life, the negative pressure ambulance, as the name suggests, is different from the normal ambulance in that it is able to realize the negative pressure isolation. This model is able to implement emergency treatment of new and sudden infectious diseases, so that the external environment is free from contamination, to prevent the further spread of the epidemic, to complete the safe isolation of major infectious patients and transportation.
In the whole vehicle, "negative pressure isolation" is the medical cabin in the back of the ambulance. Here, the system through the air conditioning and fans using the principles of fluid dynamics, in the vehicle from the clean zone (that is, the vehicle riding in the higher posture of the medical staff area), to the infectious zone (that is, lying on a stretcher patient area) directional airflow. Ultimately, the gases inside the vehicle will be sterilized by filters and discharged out of the vehicle without entering the vehicle for recirculation.
After activating the negative pressure device, the system will strongly pump the air exhaled by the patient on the stretcher, which will ultimately be sterilized by the filtering equipment and discharged out of the vehicle, making it pollution-free air. Due to the formation of the vehicle medical cabin than the external atmospheric pressure lower than 10-30Pa negative pressure, the patient's exhaled air will not be discharged from the vehicle door and window gaps out of the vehicle, can effectively prevent viruses from infecting the environment along the way. The new air entering the vehicle will also be filtered to ensure that the patient will not be infected by the external environment.

看到这里大家估计也能意识到，负压救护车对风机的工作效率要求很高。 According to the national standard, the fan in the negative pressure compartment will need to completely replace the air 20 times per hour; the system can't take more than 3 minutes from startup to the formation of the standard negative pressure value. In addition, the national standard on the sterilization capacity of the filter also put forward the corresponding requirements.
In addition to the negative pressure system, ultraviolet disinfection lamps and other in-vehicle disinfection equipment for negative pressure ambulance is also essential. Because the vehicle in the stopping phase, the system also has to disinfect the interior environment to ensure that no dead ends are left.
In addition to this, negative pressure ambulances are equipped with a full set of rescue equipment such as ventilators, defibrillators, cardiac monitors and other equipment common to ambulances, as well as installing UV disinfection lamps and central oxygen interfaces. Negative pressure ambulance is not only able to isolate the patient, the conventional ambulance trauma suture surgery, cardiopulmonary resuscitation and other rescue can be carried out in the car.
In the latest National Health Commission "new coronavirus infection of pneumonia cases transfer program (trial)" clearly stipulates that the new coronavirus infection of pneumonia cases responsible for the transfer work, as far as possible, the use of negative pressure ambulance.

What companies are currently manufacturing negative pressure ambulances
Then the ultimate question arises: how do you manufacture a negative pressure ambulance? Approximately how long and how much money will it take?
Normal production of a negative pressure ambulance goes through two steps: production of the base vehicle (a basic type of armored vehicle that can be derived from a chassis for a variety of different types and uses), and modification. In accordance with the conventional steps, in which the base vehicle production generally takes 2 weeks, and negative pressure ambulance modification, need to go through the foam insulation treatment, wiring, interior installation, electrical, medical equipment installation, negative pressure facilities installation and so on a number of steps, but also lasted 2 weeks.
And under the premise of quality assurance, to shorten the 30-day work period to 10 days, for each enterprise is undoubtedly a huge challenge. However, there are already many domestic enterprises accepting the challenge and rising to it.
