The new coronavirus is coming fiercely, and in the early days of the epidemic, due to the insufficient number of negative-pressure ambulances, it was difficult for infected patients to be effectively transferred, and it was easy to cause cross-infection. After learning of this situation, the major domestic light passenger manufacturers and refitting factories have resumed work, rushed to produce a large number of negative pressure ambulances.
Not long ago BAIC Group, together with BAIC Foton and other 10 of its automobile units, donated 40 Foton Tuyano negative-pressure ambulances to the China Charity Federation. Foton announced at the event that it would donate an additional 20 negative-pressure ambulances valued at 7 million yuan to support Wuhan in the fight against the epidemic.
Many people have been puzzled by the difference between a negative pressure ambulance and an ordinary ambulance. In fact, the negative pressure ambulance is also known as the "mobile N95", indicating that the vehicle's protective performance is much better than the ordinary ambulance. The author will combine the Tuyano negative pressure ambulance, to reveal the negative pressure ambulance in the end what is special.
At present, Tuyano negative pressure ambulance matched with the national 6 emission standard Cummins ISF?2.8 engine, displacement of 2.8L, maximum power of 130kW, maximum torque can reach 360N.m, 100 kilometers accelerated to 19.2 seconds, strong power industry-leading, to save the life of the second.
Front rear drive, matched with four-wheel disc brakes.
Exterior dimensions, Tuyano long wheelbase version of the dimensions of 5990 × 2000 × 2555/2585mm, wheelbase are 3750mm, is the largest size of the blue light passenger, can better meet the negative pressure ambulance special configuration space, internal size requirements.
As for the body, Tuyano adopts the facility style of European light passenger, this kind of model itself is more suitable for conversion ambulance. Many places in China have already purchased a large number of Tuyano ambulances, proving Tuyano's excellent adaptability and reliability. It is important to know that the negative pressure ambulance requires a lot more from the vehicle than our common ordinary ambulance, and has higher requirements for the structure of the frame, the ventilation of the body as well as the sealing and other technical parameters.
The above picture shows the internal structure of the cabin, and the large space is convenient for the layout of various equipments.
Negative pressure ambulance is also called protective ambulance, and its main purpose is to transfer patients with infectious diseases. There is a partition between the driver's compartment and the rear passenger compartment, which prevents the driver from coming into contact with the interior of the cabin and reduces the risk of infection. The driver and the rear cabin communicate via radio, while sliding windows can be opened to pass things when it is safe to do so.
There is a sliding door on the right side and the tailgate is a double door with matching exit pedals for easy access to the medical bay.
The vehicle is equipped with a negative pressure system, which consists of a negative pressure controller, an exhaust fan, a pressure display gauge, an air high-efficiency filter, an outlet assembly, an air sterilization system and other components. The strong suction and exhaust equipment will, on the one hand, allow the medical cabin to generate a relative atmospheric low-pressure difference with the external environment to ensure that the air inside the vehicle circulates according to the designed channels and does not leak casually; on the other hand, it will allow the fresh air to flow from the top to the bottom to protect the medical personnel as much as possible. The air inside the cabin will be filtered by a sterilization system and other equipment, and then discharged to the outside of the vehicle.

The pressure inside the cabin is lower than that outside, so naturally the outside air will "desperately" run into the car. To ensure that the interior of the cabin is at a stable negative pressure, the sealing of the vehicle puts forward a very big demand. Just like the common vacuum bag in our life, even if the package is only broken a small hole, then there is no pressure difference between the inside and outside, the air can flow freely.
In addition, in addition to the negative pressure system inside the vehicle, in each negative pressure ambulance is also independently equipped with a negative pressure isolation chamber for the transportation of infectious patients as shown in the picture above. It is like a small negative-pressure ambulance, and the principle is basically the same as the one we described above, on the one hand, it is to isolate the infectious patients from the outside world, on the other hand, it is to form a negative-pressure space to control the air flow.
From the negative pressure system introduced in this article can be seen, the negative pressure ambulance for the vehicle space and sealing aspects have very strict requirements. Not that any car out can be modified negative pressure ambulance, to meet certain standards to maximize its value. Foton Tuyano shoulders this important task with its strong adaptability to modification and delivers the negative pressure ambulance which is much more complicated than ordinary ambulances in just 10 days with quality and quantity guaranteed, thus letting people see Tuyano's commitment to social responsibility. We believe that with more and more professional equipments being put into the battlefield, we will be able to overcome the epidemic as soon as possible!
