Abstract:
Objective To design a pressure detection and control system in the medical compartment for bio-agent casualty emergency evacuation and en route treatment during responses to biological warfare or terrorist attack.Methods An instrument and a pressure transmitter were used for detection,display and alarm of positive and negative pressures in the medical compartment,and pulse width modulation was involved in to regulate fan speed and then to control the pressure inthe compartment.Results The system proved its ability to evacuate bio-agent casualty and fulminating infectious patient with no pollution to the environment.Conclusion The system realizes on-line monitoring of the filter absorber in the medical compartment,enhances the efficiency and reliability of casualty care and thus gains high military benefits.
