Abstract

The invention relates to a negative pressure device and an ambulance. The negative pressure device comprises two negative pressure fans, a cabin body and a differential pressure gauge, wherein the twonegative pressure fans are arranged at a tail end of the cabin body, each negative pressure fan comprises an air inlet and an air outlet, the air inlet is arranged inside the cabin body, the air outlet is formed in the outer part of the cabin body, the differential pressure gauge is arranged in the cabin body and is used for displaying the pressure difference between the cabin body and the external air pressure, the negative pressure device further comprises an air conditioner and an air conditioner control panel, the air conditioner control panel is electrically connected with the air conditioner and used for controlling the temperature T of the air conditioner, the air conditioner is used for adjusting the temperature in the cabin body, and the temperature of the air conditioner is thesame as the temperature in the cabin body. The negative pressure device is advantaged in that the rotating speed of the negative-pressure fans is adjusted according to the real-time temperature in thecabin body, so the proper temperature in the cabin body is kept, the proper pressure difference between the cabin body and the outside is kept, a comfortable and stable rescue environment is providedfor a patient, and rescue is convenient to carry out.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a negative pressure device and an ambulance. Background technique [0002] In the field of medical equipment, when patients with severe infectious diseases take ordinary ambulances on the way to seek medical treatment, transfer to hospital, etc., the viruses and highly infectious aerosol pollutants emitted by the infectious patients through physiological activities such as breathing will pass through the ambulance that is not tightly sealed. Orifices, gaps, etc. spread outwards, which may pose a threat of infectious diseases to pedestrians or nearby residents on densely populated urban traffic arteries. [0003] When transporting or first aiding patients with severe infectious diseases or biologically polluted patients, the negative pressure protection device is turned on, and the polluted air in the car passes through sub-high efficiency filters and high-efficiency filters to fi...
