An electronic sphygmomanometer includes a cuff including an air bladder, a pressure sensor, an artery volume sensor, and a computation device. The computation device includes an inner pressure control section, a volume sensor signal receive section for receiving a pulse wave signal detected by the artery volume sensor, a pressure sensor signal receive section for receiving a pressure pulse wave signal superimposed on the inner pressure of the air bladder and detected by the pressure sensor, a judgment section for choosing either the pulse wave signal or the pressure pulse wave signal as a signal for calculating pulse rate of the patient during a period when the inner pressure of the air bladder is increased and/or decreased by the inner pressure control section, and a pulse rate calculation section for calculating pulse rate of the patient based on the pulse wave signal and the signal chosen by the judgment section.

Electronic sphygmomanometer for measuring blood pressure and pulse

A blood pressure and pulse measurement device includes a cuff including a first air bladder, a pressure sensor, a pressing member, a pulse wave sensor, and an operation unit. When measurement of the blood pressure is instructed by the operation unit, the first air bladder of the cuff is inflated to increase inner pressure to a sufficient level such that the blood pressure of the patient can be measured by the pressure sensor and then deflated. When measurement of the blood pressure is not instructed by the operation unit, air of the first air bladder of the cuff is released such that the measurement location of the patient is not substantially pressed by the first air bladder, and the measurement location of the patient is pressed by the pressing member with sufficient pressure such that pulse of the patient can be detected by the pulse wave sensor.
