Abstract: A cuffless blood pressure monitor is revealed. The cuffless blood pressure monitor includes a pressure detection module, a signal processing module and a display module. The pressure detection module detects blood pressure to generate a blood pressure pulse signal. The signal processing module processes the blood pressure pulse signal to generate a measurement result that is displayed by the display module. The cuffless blood pressure monitor measures continuous blood pressure pulse signals, processes the blood pressure pulse signals by the signal processing module, and calculates the measurement result for real-time measurement of blood pressure. A measurement point on the user is pressed by a soft pressure-transferring medium so that the user won't feel uncomfortable. Moreover, the cuffless blood pressure monitor is compact and portable.

Abstract: The impedance measuring device of the present invention is a self-operated pressure point impedance measuring device. The device can quantitatively measure the impedance of the pressure point in digital format. The qualified impedance data can be on-line interface to a PC computer for recording and further application using USB protocol. The configuration of device includes a hand-held body or with a parallel connected unit as a current loop; a flexible round point as a measuring point, and an impedance sensing circuitry. This impedance measuring device of the present invention can significantly provide convenience to the users for measuring the impedance.
