Description
Technical Field
The utility model relates to an ambulance equipment technical field, concretely relates to negative pressure ambulance exhaust filtration degassing unit.
Background
The biggest characteristic of the negative pressure ambulance is negative pressure. The negative pressure is that the air pressure in the vehicle is lower than the external atmospheric pressure by using technical means, so that the air can only flow out of the vehicle to the vehicle when flowing freely, and the negative pressure can discharge the air in the vehicle after harmless treatment, thereby avoiding more people from being infected, and reducing the probability of cross infection of medical staff to the maximum when treating and transporting special diseases such as infectious diseases. The existing negative-pressure ambulance directly discharges gas through a filtering device, the discharged gas is difficult to ensure to be clean, and a small amount of infection sources, bacteria, viruses and the like in the discharged gas are often discharged into the atmosphere.
