The biggest feature of this car is negative pressure. The so-called negative pressure is the use of technical means, so that the car pressure is lower than the outside atmospheric pressure, so the air can only flow outside the car when the free flow of the car, and the negative pressure can also be discharged after the harmless treatment of the air inside the car In order to prevent more people from being infected, the probability of cross-infection among medical personnel can be minimized when treating and transporting special diseases such as infectious diseases. The vehicle is also equipped with a full range of rescue equipment such as a ventilator, a defibrillator, and an ECG monitor. UV-disinfection lamps and a central oxygen interface are installed. After the debridement and suture resuscitation can be performed on the ambulance. This is unimaginable on an ordinary ambulance. It is mainly used for the rescue of critical diseases such as critically ill patients and infectious diseases. National Ministry of Health requirements: 20 air changes per hour, negative pressure between -10Pa and -38Pa, filtration separation rate of 99.9% --------- The negative pressure in the negative pressure ambulance patient compartment refers to the relative pressure difference between the cabin and the outside atmosphere. It mainly relies on the exhaust fan to actively vent the outside air and seal the cabin. Before the patient room air is discharged to the atmosphere, it is generally filtered by a high-efficiency filter (99.97%@0.3um), which can effectively reduce the spread and pollution of patient microbes to the ambulance to the external environment. This method is only a physical isolation method. Bacteria and viruses are blocked on the surface of high-efficiency filters and cannot be killed. Ambulances should be used after ambulances are used. At present, there are many kinds of integrated negative pressure exhaust purification devices, such as the "negative pressure ambulance exhaust purification device" of the National Biological Protection Equipment Engineering Technology Research Center, and the patent number. Integrate high-efficiency filter, fan, and electric control together, featuring easy installation, small footprint, and high filtration efficiency.
