PROBLEM TO BE SOLVED: To easily measure the heart rate at the time of bathing by providing a pair of electrodes in contact with water on the inner face of a bathtub, and providing an arithmetic section amplifying and counting the signal proportional to the heart beat of a bather detected by the electrodes and displaying the heart rate on a digital display face on the inner wall of a bathroom. SOLUTION: A pair of electrodes 6, 6 are exposedly provided on the inner face of a bathtub 2 in a bathroom 1, a heart beat counting device 3 having a digital display face 5 is buried and fixed on the inner wall 4 of the bathroom 1, or it is hooked on the inner wall 4. The heart beat counting device 3 receives the pulse signal having the frequency proportional to the heart beat generated from the body of a measured person, and it clock-counts the number of pulses or pulse signal noises in a fixed time for one cycle period to obtain the count value proportional to the heart beat. The count output is displayed on the digital display face 5 as the heart beat. The heart rate can be simply and easily confirmed during bathing, and a cerebral apoplexy accident during bathing is prevented. |
