Negative pressure ambulance capable of preventing cross infection of doctor and patient

Abstract

The invention discloses a negative pressure ambulance used to prevent nosocomial infection, containing car body, hermetic board cabin connected with car body chassis, control device; the hermetic board cabin is consisted of nose functional cabin and medical afterhold; the nose functional cabin is the flow direction of air controlling cell, the medical afterhold contains cabin air inlet chamber, cabin exhaust chamber, also a medical equipment in cabin; the medical afterhold sets closable port; the cabin air inlet chamber of medical afterhold and air mixing chamber of nose functional cabin can be connected, the cabin exhaust chamber of medical afterhold and the air filtration disinfection chamber can be connected. The air flow of hermetic board cabin has three kinds of state, the air in cabin can all realize directional airflow and pressure gradient. This car can be used as normal ambulance, high pathogenic infectious patient ambulance, various diseases checking car, mobile p3 lab, carrier vehicle of biological bacteria danger foe things; it can be asepsis operation car after switching, high infectivity, strong virulence weapon battlefield command, arm carrying car.

Description

technical field [0001] The invention belongs to a rescue device, and in particular relates to a driver's cab and a large airtight cabin or carriage which form independent isolation barriers. The air in the cabin is all flowing, and has multiple functions such as fresh air, full internal circulation, and supplementary partial fresh air. Functional directional airflow and pressure gradient work environment negative pressure ambulance. Background technique [0002] At present, when highly infectious or highly virulent patients are treated and transported at home and abroad, they are generally transported by conventional ambulances, and the windows of the vehicles are opened on the way to ventilate; subsequently, an exhaust ventilation device was added in conventional ambulances without disinfection The polluted gas in the compartment is directly discharged; and then the direct discharge is changed to an ambulance discharged after simple filtration. In addition, the existing am...

AI Technical Summary

Problems solved by technology

In addition, the existing ambulances with additional devices have no special improvement in the sealing of the doors and windows of the compartment, which is basically the same as that of conventional ambulances. Therefore, the sealing effect is not good, the pathogens (viruses) in the compartment are easy to spread to the outside, and there are a large number of dead spots in the compartment. and eddy currents, increasing the probability of cross-infection, that is, cross-infection between drivers, medical staff and patients
