Negative pressure ambulance means that the air inside the vehicle is harmlessly processed and discharged to avoid more people infected, in the rescue and transfer of infectious diseases and other special diseases can be minimized to reduce the chances of cross-infection of medical personnel.
Cleansing and suturing surgery and cardiopulmonary resuscitation can be carried out in the ambulance, which is mainly used for the rescue of critically ill patients and special diseases such as infectious diseases.
Expanded Information:
Negative pressure ambulance filtration system is known as the "oversized N95 mask", its most important feature is the "negative pressure isolation", so that the outside environment from contamination, to prevent further spread of the epidemic! It is mainly used for the safe isolation and transportation of major infectious diseases. In the current severe situation of epidemic prevention, negative pressure ambulance is in short supply of advanced technical equipment.
It is reported that the car medical cabin and cab isolation, cabin installed a strong suction, exhaust equipment, the set of negative pressure system to control air flow in the medical cabin air to form a directional flow, medical cabin and the external environment to form a relative low-pressure difference in the atmosphere, so that bacteria, viruses will not be spread through the car to the outside air.
Negative pressure ambulance filtration system, the chief technical expert said that the negative pressure system, not only can prevent droplets, but also efficient filtration of aerosols. The filtration efficiency specified in the health industry standard is 99.7%. The system is in accordance with the requirements of nuclear, biological and chemical protection, according to China's national standard measurement, the filtration efficiency should reach 99.999%.
Based on the characteristics of the new coronavirus infection, the system has used bioinactivation components to completely kill pathogenic microorganisms trapped on the filter cartridge before replacing the filter components.
