Abstract: A method for detecting vascular sclerosis is revealed. Firstly set a cuff on a human hand. Then inflate the cuff and later deflate the cuff. Next measure a pressure of the cuff and generate a pressure sensing signal. Process the pressure sensing signal to generate a processed signal and convert the processed signal. Then calculate a systolic pressure and a diastolic pressure according to the converted processed signal and also obtain a vasodilation constant. Thus a hardening of blood vessels is detected according to the vasodilation constant.

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.
