Abstract: A washing device includes a container (10) in which aqueous solution is contained, an adsorption electrode (11) which is placed in the container (10) and on which adsorption and desorption of ions in the aqueous solution can be brought about, a counter electrode (12) which is placed in the container (10) so as to face the adsorption electrode (11), a direct-current power source (20) for applying a voltage between the adsorption electrode (11) and the counter electrode (12), and a switching circuit (30) for switching polarity of the voltage applied between the adsorption electrode (11) and the counter electrode (12).

Abstract: A measurement data communication device of the present invention transmits, to an information acquisition device, a measured value which indicates the health condition of a measurement target. In this measurement data communication device, a communication section transmits, to the information acquisition device, communication information including a measurement name corresponding to the measured value and a code value corresponding to the measurement name. Also, a measurement data generation section generates measurement data from the code value and the measured value. The measurement data communication device of the present invention can therefore cause the information acquisition device to recognize the measurement name corresponding to the code value, when measurement data communication device transmits the measurement data to the information acquisition device.
