Infectious disease patient conveying and isolating unit capable of maintaining negative pressure for long time

Abstract

The invention belongs to the technical field of aviation medical rescue, and specifically relates to an infectious disease patient conveying and isolating unit capable of maintaining negative pressurefor long time. The infectious disease patient conveying and isolating unit comprises an isolation unit cabin, an air inlet filter, exhaust filters, air circulation control systems, a filter replacement additional mechanism and a medical material supplement buffer channel, wherein the air inlet filter is arranged at the head end of the isolation unit cabin, and the tail end of the isolation unit cabin is connected with the medical material supplement buffer channel; the exhaust filters are arranged at the other end of the medical material supplement buffer channel; and the filter replacement additional mechanism and two sets of air circulation control systems are arranged in the medical material supplement buffer channel. Long-time negative pressure continuous maintaining capacity, efficient pathogen gas filtering capacity and the capacity of medical aid materials outside the isolation unit entering the isolation cabin body under the aviation environment condition are achieved, and therequirement for long-time long-distance air transportation and back delivery of infectious disease patients is met.

Description

technical field [0001] The invention belongs to the technical field of aviation medical rescue, and in particular relates to an infectious disease patient transportation isolation unit capable of maintaining negative pressure for a long time. Background technique [0002] During air medical evacuation of patients with infectious diseases, the transfer time depends on the distance of the transfer, and is usually affected by factors such as the duration of negative pressure, the effective filtration time of the high-efficiency filter, and the ability of the patient to maintain the effective space in the isolation cabin. , Transit time is usually not more than 4 hours. In the active evacuation equipment for patients with infectious diseases using products on the ground, the pressure change in the cabin caused by the increase / decrease of the flight altitude during the flight process has not been considered, resulting in insufficient negative pressure maintenance capacity; the co...

AI Technical Summary

Problems solved by technology

In the active evacuation equipment for patients with infectious diseases using products on the ground, the pressure change in the cabin caused by the increase / decrease of the flight altitude during the flight process has not been considered, resulting in insufficient negative pressure maintenance capacity; the continuous working time of the high-efficiency filter It is difficult to meet the filtration requirements of more than 4 hours; and the medicinal materials, dressings, instruments and other medical rescue materials required for the rescue of the wounded and sick during the evacuation cannot enter the interior of the isolation cabin, and it is difficult to meet the use requirements, etc.
