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.
ABSTRACT
We have designed a mobile operating room information management system. The system is composed of a client and a server. A client, consisting of a PC, medical equipments, PLC and sensors, provides the acquisition and processing of anesthesia and micro-environment data. A server is a powerful computer that stores the data of the system. The client gathers the medical device data by using the C/S mode, and analyzes the obtained HL7 messages through the class library call. The client collects the micro-environment information with PLC, and finishes the data reading with the OPC technology. Experiment results showed that the designed system could manage the patient anesthesia and micro-environment information well, and improve the efficiency of the doctors' works and the digital level of the mobile operating room.
