摘要: A first, second and third electrode, an electrode contact detection means configured to detect and output a state in which all of the electrodes are in contact with a surface of a measurement target, and control means configured to execute a measurement process of biological information, wherein the electrode contact detection means includes a bias power source configured to apply a voltage to each of the first electrode and the second electrode, a first comparator and a second comparator, and a contact state determination unit configured to determine whether all of the electrodes are in contact with the surface of the measurement target based on outputs of the first comparator and the second comparator, and the control means is configured to execute a process for opening the bias power source and executes the measurement process only when all electrodes are in contact with the surface of the measurement target.

摘要: In a main body of an upper-arm type sphygmomanometer that measures blood pressure of a subject by using a bag-shaped arm cuff to be wound around an arm of the subject, a main body housing includes an upper surface, and a first side surface and a second side surface on left and right sides. The first side surface includes a first side surface electrode region, the second side surface includes a second side surface electrode region, the upper surface includes a first upper surface electrode region, a first electrocardiogram waveform measurement electrode is provided in the first side surface electrode region, a second electrocardiogram waveform measurement electrode is provided in the second side surface electrode region, and a first reference electrode is provided in the first upper surface electrode region.
