<p>PROBLEM TO BE SOLVED: To provide a bathtub hemodynamometer for measuring the blood pressure of a bathing person in real time. SOLUTION: The bathtub hemodynamometer 1 comprises a heartbeat measuring means 2 for measuring the heartbeat timing of a bathing person, a pulse wave measuring means 3 for measuring the pulse wave at a measured part on the body surface of the bathing person, a propagation time deducing means 4 for deducing the propagation time of the pulse wave from the heart to the measured part, an average blood pressure deducing means 5, and a blood pressure deducing means 6. The average blood pressure deducing means 5 deduces the propagation speed of the pulse wave based on the pulse wave propagation distance and propagation time from the heart to the measured part and deduces the average blood pressure at the measured part based on a prescribed first relation between the pulse wave propagation speed and the blood pressure. The blood pressure deducing means 6 deduces the blood pressure at the measured part based on a prescribed second relation between the pulse wave and the blood pressure, and the average blood pressure.</p> |
