The invention discloses a positive and negative pressure ambulance. The cabin of the positive and negative pressure ambulance is divided into a cockpit, a decontamination cabin and a medical cabin; A positive pressure fan is provided, and a negative pressure fan is provided at the bottom of the medical cabin. The positive and negative pressure ambulance also includes an air intake system and an exhaust system; the air intake system includes an air intake purification and disinfection device connected in sequence, a positive pressure fan , The first electric air valve, the air intake system also includes a three-way pipeline, the air inlet of the three-way pipeline is connected to the first electric damper, the first air outlet of the three-way pipeline is directly connected to the fresh air air conditioning system, three The second air outlet of the pipeline is connected to the fresh air air conditioning system through the manual air valve; the exhaust system includes an exhaust purification and disinfection device, a negative pressure fan, and a second electric air valve connected in sequence. The invention can solve the problems in the prior art that the polluted gas outside the vehicle easily enters the cabin and the polluted gas in the cabin easily leaks out of the vehicle.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a positive and negative pressure ambulance. Background technique [0002] With the global spread of COVID-19, medical protective equipment has become the focus of the industry. At present, the demand for ambulances is increasing, especially the need for ambulances that can transfer patients with COVID-19 is even more urgent. [0003] At present, ordinary ambulances usually only have normal vehicle functions, including air-conditioning heating and cooling systems, natural air pressure, etc. The occupants can breathe normally, but when the vehicle enters the virus-contaminated area, the polluted gas is easy to enter through the vehicle's door cracks, etc. In the cabin, causing pollution to the occupants. In addition, when a virus-infected patient is transported in the cabin, the gas exhaled by the virus-infected patient will leak out of the vehicle, causing pollution to the en...
