Positive pressure and negative pressure ambulance

Abstract

The invention discloses a positive pressure and negative pressure ambulance. A cabin of the positive pressure and negative pressure ambulance is separated into a driving cabin, a washing and disinfecting cabin and a medical care cabin, wherein a fresh air conditioning system is arranged at the top of the driving cabin; a positive pressure fan is arranged at the upper part of the washing and disinfecting cabin; negative pressure fans are arranged at the inner bottom of a cabin body of the medical care cabin; the positive pressure and negative pressure ambulance also comprises an air inlet system and an exhaust system; the air inlet system comprises an inlet air purifying and disinfecting device, the positive pressure fan and a first electric air valve which are sequentially connected; the air inlet system also comprises a tee pipeline; an air inlet of the tee pipeline is connected with the first electric air valve; a first air outlet of the tee pipeline is directly connected to the fresh air conditioning system; a second air outlet of the tee pipeline is connected to the fresh air conditioning system through a manual air valve; and the exhaust system comprises an exhaust purifying and disinfecting device, a negative pressure fan, and a second electric wind valve which are sequentially connected. Through the adoption of the positive pressure and negative pressure ambulance disclosed by the invention, the problems that in the prior art, pollution gas outside the ambulance is easy to enter the cabin, and pollution gas in the cabin is easy to leak outside the ambulance are solved.

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...
