PROBLEM TO BE SOLVED: To recognize not only a heart function but also the circulatory function of the whole body, to improve safety at the time of bathing and to perform easy and non-troublesome electrocardiogram/pulse wave measurement by obtaining an electrocardiogram, a heart rate and a pulse wave, measuring pulse wave propagation time from them further and displaying it. SOLUTION: The electrocardiogram is measured by processing electric signals from an electrode 1a provided on one inner side wall inside a bathtub main body 5, the electrode 1b provided on the other inner side wall and a ground electrode in an electrocardiogram measurement part 2a and is displayed at a display part 4. Also, when a finger tip touches the light emitting body and light receiving body of a pulse wave sensor 6 attached to the frame part of the bathtub main body 5, the change of the transmissivity of light is processed in a pulse wave measurement part 2b and the pulse wave is measured and displayed at the display part 4. Such electrocardiogram measurement part 2a and pulse wave measurement part 2b perform parallel processings and the R wave of the electrocardiogram and the deviation of the time of the peak value of the pulse wave are calculated in a control part 35 and displayed. Thus, the physiological change and risk phenomenon of a body at the time of bathing are easily ascertained. |
