The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse wave. The complexity of the variability of these...
Recent microwave nondestructive measurement in biomedical engineering are reviewed. A novel method for non-contact monitoring of stress-induced autonomic activation through the back of a chair is developed, using a compact 24 GHz microwave radar (8 × 5 × 3 cm), without large scale equipment and placing a heavy burden on the monitored individual. This method appears to be promising for future monitoring...
A new kind of wrist-worn health monitoring terminal is developed to realize multi-parameter measurement, wearing facilitates and reliable data transmission. The physiological parameters includes body temperature, pulse rate, breath rate and waveform, blood pressure, electrocardiograph(ECG), electroencephalogram(EEG) and the level of blood glucose real-timely. This terminal is designed by modules,...
The clinical significance of certain cardiac arrhythmias can be understood only with reference to respiration. In normal healthy conditions, the respiratory rate is 10-20 breaths/minute. But, certain problems of illness, accidents or some other causes affect the regular sinus rhythm. A non-invasive, non-occlusive and non-intrusive respiration monitoring is desirable in a number of situations such...
A portable system to monitor environmental factors of pulmonary diseases is introduced in this paper. Disease triggers including temperature, humidity and airborne particles are continuously measured in real time. Data is transferred to a handheld device through a wireless body area network (BAN). If target triggers of disease are detected, the system will provide alarms and instructions to the patient...
Heart diseases are the serious health threats to human beings. Traditional cardiac monitoring systems are unsatisfactory to prevent the sudden death events caused by heart diseases. A pervasive cardiac monitoring system is thus developed, which can provide a real-time continuous cardiac care and arrhythmias detection service for any person at any time in any place. This paper gives a detailed description...
A simultaneous monitoring system for blood pressure and blood oxygen saturation based on the volume-oscillometric method and the dual-wavelength spectrophotometry is developed, and principle of the dual-wavelength spectrophoto-metry for measurement of blood oxygen saturation is introduced in this research. Also, the local pressurizing cuff unit and the photo-detector are development. A preliminary...
Remote Home Monitoring System is one of important steps of the national medical and health system innovation. In this paper, we present a Remote Home Monitoring System (RHMS) which is consisted by the client side that in patients' houses and the server side that in hospitals. The key points are the design of client side software and multimedia interactive technology. The Visual C++ and SQL programming...
Extra-corporal Circulation Support Systems (ECCS) are used in cardiac surgery on a daily basis. Surgeons and perfusionists supervise patients' vital signals such as heart rate or blood pressure and ensure secure and errorless operation of the ECCS. Latest developments clear the way to use an ECCS for emergency circulatory resuscitation in non-clinical environments, even when trained staff is sparse...
In this paper, we present a portable intelligent electrocardiogram (ECG) monitoring system using the Zigbee wireless network technology. The system consist of both hardware and software development. For the hardware development, a Field Programmable Gate Arrays (FPGA), ECG sensor, preprocessing circuit, Zigbee transmission module, and external memory are used. And the FPGA with a Nios II soft-core...
This paper proposes design ideas for personalized medical testing technology of healthy smart home. The system architecture and design of physiological parameter detection sensors with wireless, low-costing and low power consumption are expounded. And the study of ECG monitoring in this system is presented to solve the key problem of ambulatory physiological parameter monitoring. Moreover, a design...
