Acupuncture points and skin impedance.
OVERLAPPING OF MERIDIAN AND VEIN A superficial vein named the median vein located on the midline of the anterior forearm is a common site for phlebotomy. It is rather parallel to the invisible PC4 and pericardial meridian (figure 1), although individual mappings of the vein are not uniform. The veins have thin elastic walls and blood flowing inside; electrically they are very conductive. Mechan...
متن کاملSkin Impedance Measurements for Acupuncture Research: Development of a Continuous Recording System
Skin impedance at acupuncture points (APs) has been used as a diagnostic/therapeutic aid for more than 50 years. Currently, researchers are evaluating the electrophysiologic properties of APs as a possible means of understanding acupuncture's mechanism. To comprehensively assess the diagnostic, therapeutic and mechanistic implications of acupuncture point skin impedance, a device capable of rel...
متن کاملElectrical skin impedance at acupuncture points.
OBJECTIVES To test whether electrical skin impedance at each of three acupuncture points (APs) is significantly lower than at nearby sites on the meridian (MP) and off the meridian (NP). DESIGN Two instruments - Prognos (MedPrevent GmbH, Waldershof, Germany), a constant-current (DC) device, and PT Probe (designed for this study), a 100-Hz sinusoidal-current (AC) device-were used to record ele...
متن کاملA Low-Power and Portable Biomedical Device for Respiratory Monitoring with a Stable Power Source
Continuous respiratory monitoring is an important tool for clinical monitoring. Associated with the development of biomedical technology, it has become more and more important, especially in the measuring of gas flow and CO2 concentration, which can reflect the status of the patient. In this paper, a new type of biomedical device is presented, which uses low-power sensors with a piezoresistive ...
متن کاملA Wideband Current-mode, Low-Voltage, Low-Power CMOS Frequncy- insensitive Quadrature Phase Shifter
A CMOS frequency-insensitive quadrature phase shifter is presented. Due to operation in current-mode, the proposed circuit provides a wide frequency response, a low supply voltage, low power consumption and electronic controllability. Thus, it is very suitable for use in portable and battery-powered equipments. The feature of the proposed circuit is that it can provide the quadrature signals wi...
