Abstract

This biological information measurement device is provided with: a first electrode; a second electrode; a third electrode; an electrode contact sensing unit that senses and outputs a state in which all the electrodes are in contact with a surface of a measurement object; and a control unit that performs measurement processing of biological information, the electrode contact sensing unit being provided with: a bias power supply that applies 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 that determines whether or not all the electrodes are in contact with the surface of the object to be measured on the basis of the output of the first comparator and the output of the second comparator, and the control unit performs a process of turning off the bias power supply only when all the electrodes are in contact with the surface of the object to be measured, and performs a process of turning off the bias power supply only when all the electrodes are in contact with the surface of the object to be measured. And performing measurement processing.

Description

technical field [0001] The invention belongs to the technical field related to health care, and particularly relates to a biological information measuring device. Background technique [0002] In recent years, information related to an individual's body / health (hereinafter, also referred to as biological information), such as blood pressure values ​​and electrocardiographic waveforms, has been measured by measuring equipment, and the measurement results have been recorded and analyzed through information terminals. This situation of health management is spreading. [0003] As an example of the above-mentioned measuring apparatus, a portable electrocardiographic measuring apparatus that measures electrocardiographic waveforms immediately when abnormality such as chest pain and palpitations occurs in daily life is proposed. contribution to the treatment of (eg, Patent Document 1, etc.). [0004] Patent Document 1 discloses a portable electrocardiograph equipped with three el...
