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, in particular to a driver's cab and an airtight large-slab shelter that form independent isolation barriers, the air in the cabin is flowing, and has multiple functions such as fresh air, full internal circulation, and supplementary partial fresh air. Negative pressure ambulance for airflow and pressure gradient working environment. 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 ambulances with additional devices have...

Embodiment Construction

[0022] Such as figure 1 As shown, the vehicle body 100 is an automobile with a second-type chassis 101 , and the chassis 101 is connected to the airtight large board shelter 200 through a connecting piece 102 . The structure of the vehicle body 100 is understood by those skilled in the automotive field, and the structure thereof will not be repeated here. A shovel-type stretcher box 201, an air-conditioning condenser box 202, and an auto parts box 203 are set under the airtight large board shelter 200. Sealing box doors 204, 205 and sealing windows 206 are arranged on the sides of the airtight large slab shelter 200 . A flashlight 207 is provided on the top of the case. The driver's cab 110 of the vehicle body 100 is separated from the airtight large plate shelter or compartment to form independent spaces.

[0023] Such as image 3 As shown, the air inlet device 300 is provided at the front end of the airtight large board shelter 200, and the air inlet device 300 includes ...
