BLOOD PRESSURE DETECTING DEVICE, BLOOD PRESSURE DETECTING METHOD, BLOOD PRESSURE DETECTING PROGRAM, AND STRAIN SENSOR FOR BLOOD PRESSURE DETECTION

摘要

PPROBLEM TO BE SOLVED: To provide a blood pressure detecting device and a blood pressure detecting method which are capable of accurately obtaining the highest blood pressure and the lowest blood pressure based on a principle different from a conventional one, and detecting the blood pressure in the state in which the heart rate is weakened, or in the state in which the body of a subject moves during the exercise, etc., and a strain sensor for blood pressure detection and a blood pressure detecting program which are used in the blood pressure detecting device. PSOLUTION: The blood pressure detecting device 11 or 81 comprises a pulse wave detecting means 21 with the strain sensor 22 for blood pressure detection, a pressure means 31 for pressing a blood vessel by pressing a living body and gradually reducing the pressure, and a blood pressure recognizing means 41 for recognizing the pressure. The blood pressure recognizing means 41 recognizes the pressure when a notch first appears in the pulse waveform which is obtained by an output means 71 for outputting the pulse waves obtained from the pulse wave detecting means 21 in the process of gradually opening an artery from when the artery is closed, or obtained by the pulse detecting means 21 in the process of opening the closed artery, as the highest blood pressure A, and recognizes the pressure when the notch disappears as the lowest blood pressure B.
