The biggest difference between a negative pressure ambulance and a regular ambulance is the ? Negative pressure? The word "negative pressure" is used. It can be understood as a special kind of ambulance that puts a mask on an ordinary ambulance. It is a special type of ambulance that blocks the flow of air between the inside and the outside of the vehicle to achieve complete isolation. It is a special ambulance made to deal with infectious diseases.
Inside the negative-pressure ambulance there is a separate space for sterilization and filtration. In this space can complete the exchange of air inside and outside the vehicle. This space is called negative pressure warehouse. It can effectively prevent the spread of viruses. It is absolutely safe and hygienic with good characteristics such as sterilization, antiseptic, ventilation and isolation. Therefore, it is used for transportation. Infectious disease patients is very suitable. Negative pressure ambulance car patient stretcher set up on a special air recovery port. It will extract the air exhaled by the patient and then filter and sterilize it before discharging it out of the car. Because the air pressure of the medical compartment inside the vehicle is lower than the outside air pressure, the dirty air inside the vehicle will not flow out of the vehicle. Therefore, it will not pollute the external environment.
Negative pressure ambulance pathogenic compartment and the relative pressure difference between the outside atmosphere, after the exhauster to the outside world, will filter the air inside. Reduce the possibility of pathogenic microorganisms spread to the outside world. But this is only a physical isolation method. He can only play the role of isolation, can not be completely killed. Therefore, the negative pressure ambulance should be sterilized immediately after use.
Negative pressure ambulance can do effective isolation of infected people, like a sterile room, effectively reducing the possibility of cross-infection of patients and health care workers. Can also avoid more people infected. Can effectively prevent infectious diseases through the airborne category. Fresh air from outside flows into the ward, while dirty air inside the ward does not leak out directly. It needs to be fully processed to ensure that it is safe before it is discharged to the outside world. Therefore, the negative pressure ambulance as a first aid and transportation of infectious disease patients play a very big role!
