BATHTUB ELECTROCARDIOGRAPH

PURPOSE:To conduct accurate measurement of subjects even in the plural subjects bathe at the same time by making the subjects grip by hand different electrodes provided with insulation materials on the upper portion of a bathtub which is not immersed in water and using the whole stainless steel bathtub as an indifferent electrode. CONSTITUTION:Different electrodes 1a, 1b are fitted through insulation materials to both side upper portions of a stainless steel made bathtub 4 that are not immersed with water. Also, the whole of the bathtub 4 is made to an indifferent electrode 1c. A subject enter the bathtub 4 filled with hot water and grips the different electrodes 1a, 1b by means of both hands, and turns on the power source switch 5 and transmission switch 6 of a main body portion 2. At electrodes 1a-1c, electric currents are run in accordance with an electrocardiowave form through the body of the testee, and processing is conducted at a CPU, and the electrocardiowave form is indicated at a monitor 7, and the number of heartbeats is indicated 8. As a result, even though the subject bathes with an attendant at the same time or moves, the data of the subject alone are accurately measured.
