ABSTRACT
The wearable respiratory inductive plethysmograph(RIP) system is a non-intrusive respiratory monitoring system. Sleep monitoring was performed on 9 human subjects suspected of having sleep apnea hypersomnolence syndrome (SAHS) and 7 healthy volunteers using both the wearable RIP system and the conventional polysomnography(PSG), and the sensitivity and specificity of the wearable RIP system were analyzed by comparison with the PSG results. According to the characteristic of the wearable RIP system in detecting sleep apnea/hypopnea event, the diagnostic criteria of sleep apnea/hypopnea event were put forward. All subjects with SAHS diagnosed by the wearable RIP were confirmed by PSG,the sensitivity and specificity of the wearable RIP system for detecting sleep apnea/hypopnea events were 99.0% and 94.6% respectively. The wearable RIP system can be used reliably in detecting sleep apnea/hypopnea events. This system can be used at home for detecting the sleep apnea/hypopnea events non-intrusively.

Objective To develop a new type of respiratory inductive plethysmograph to achieve high signal-noise rate(SNR)and low system power cost,and also to eliminate the cross-talk between chest and abdominal band sensors.Method Either of the two bands was powered by a very high power oscillator in a very short time,and these two bands were switched on in turn.The sensor structure of the respiratory inductive plethysmograph was modified so that these two bands could be embeded in a shirt conveniently.Result With these new designs,the cross-talk between these two bands was greatly eliminated and high SNR and low system power cost were achieved.This new wearable respiration monitoring system is easy to use,and can be used for long time and ambulatory monitoring.Conclusion This new system meets the design requirement with excellent performance.With this new wearable respiration monitoring system,non-invasive measurement of ventilation and non-intrusive detection of sleep apnea event can be achieved.
ABSTRACT
S95-100field mobile medical system is a field mobile hospital composed of such function cells as medical shelters,tents,special vehicles and transportable containers.Several logistic functions of the cells are introduced including patients checking and sorting,surgery,pre-operation preparation,emergency,clinical laboratory,medical supply,X-ray diagnosis,sterilization,medical command and communication,patient holding ward,logistic technical support and connection.The whole system assignments by different modules clipping and transformations,the application tests and widen tryouts in the army are alsopresented.
ABSTRACT
Objective To research a set of information system to improve the ability of rescue on mobile hospital. Methods The industry server and shelter client were used for establishing the network system of medical information, which used telemedicine in satellite communication, analyzed hardware topology and software demand. The measures of increasing safety and reliability were provided. Results The medical information was transmitted by network to share; the transmitting speed of remote diagnosis was 768Kb/s and dynamic image in 25 frame per second. Conclusion The level of the hospital informationization was improved for designing the IMS in modular thought.
ABSTRACT
System engineering of medical equipment is a specialist branch of system engineering.The chief objective of its study is to organize the system;to establish target and index system for the complex fac- tors of medical equipment through theory and method of system science,then to conduct foreast,analysis, decision,optimization,control,realization,operation and management etc.It mainly contents involves charac- teristic and aim of medical equipment system;system behavior and modularity;environment adaptation and confort of the humun body;demand and economic analysis;practicability and reliability analyals;system forecast and decision;system optimization and evaluation.
