Abstract
Abstract An apparatus for measuring data of a living body by contacting a probe to the living body or by inserting it in the living body. The apparatus comprises a living body data detecting circuit for electrically detecting data of a living body and a living body data processing circuit for digitally processing the detected data of the living body. The signals are exchanged between the living body data detecting circuit and the living body data processing circuit under an electrically insulated condition. Preferably, there are provided a first power source circuit which supplies electric power to the living body data detecting circuit only and a second power source circuit, which supplies electric power to the first power source circuit, and the electric power is supplied from the second power source circuit to the first power source circuit under the electrically insulated condition. Preferably, furthermore, the electric bias quantity applied to the detector element in the probe is compared with the bias quantity that is fed back through the detector element, in order to detect the presence of any leakage current in the living body. More preferably, an electric quantity of an element for correcting electric charateristics of the detector element in the probe is read prior to measuring the data of a living body, in order to make sure the presence of probe connection and the type thereof.
