RÉSUMÉ
Objective To acquire the physiological parameters such as pulse,blood oxygen saturation and ECG to realize personal health information monitoring and tailored medical service.Methods A personal health information acquisition terminal was developed,which was composed of an information acquisition module,personal computer and system software.The information acquisition module was developed with USB interface and unified circuit mode.Health information was transmitted to the personal computer at real time with USB interface,and then stored by system software and uploaded to the database.Results The terminal gained advantages in design,convenience and practicability,which realized realtime acquisition,data storage,remote auxiliary diagnosis,printing and etc of personal health information,so that personal information realtime monitoring was implemented.Concluslon The terminal can be used for health information recording,storage,acquisition and analysis,and extends medical service of hospital.

Non-drug treatment of hypertension has become a research hotspot, which might overcome the heavy economic burden and side effects of drug treatment for the patients. Because of the good treatment effect and convenient operation, a new treatment based on slow breathing training is increasingly becoming a kind of physical therapy for hypertension. This paper explains the principle of hypertension treatment based on slow breathing training method, and introduces the overall structure of the portable blood pressure controlling instrument, including breathing detection circuit, the core control module, audio module, memory module and man-machine interaction module. We give a brief introduction to the instrument and the software in this paper. The prototype testing results showed that the treatment had a significant effect on controlling the blood pressure.

Surface myoelectric signal analysis has proved effective for assessing the electrical manifestations of localized muscle fatigue. In the past, the analysis of muscle fatigue was restricted to isometric, constant force contractions due to the limitation of signal processing technique. The development and recent availability of spectral estimation techniques specifically designed for nonstationary signal analysis have made it possible to extend the employment of muscle fatigue assessment to dynamic contractions, thus opening new application fields such as ergonomics rehabilitation and sports medicine. This paper reviews the current study achievements of using surface myoelectric signals in muscle fatigue assessment, particularly in that during dynamic contractions. The conclusions provide theoretical bases for encouraging further studies on the mechanisms of muscle fatigue.
