Abstract
We developed a new cuff-less blood pressure measuring instrument using our phase shift technology. Using the new device we can continuously and noninvasively get information on the blood pressure per pulsation of the blood vessel. However the traditional medical device used in hospital or in our house is not able to measure continuously the blood pressure. Over the past many years, there have been numerous studies on cuff less blood pressure monitor, but a new medical device capable of detecting invasively blood pressure have not been developed. This study describes development of a new type of cuff-less blood pressure instrument which is designed to operate with an optical sensor.
