Abstract: In a pulse wave signal processor, a first filter attenuates a frequency component in an acquired pulse wave signal or in a differentiated pulse wave signal, and the attenuated frequency component is more than or equal to a first frequency. A second filter attenuates a frequency component in the acquired pulse wave signal, and the attenuated frequency component is less than the first frequency and more than or equal to a second frequency. A characteristic-point extractor extracts a characteristic point that exists in each single pulse of the pulse wave signal filtered by the second filter, and a signal separator partitioning the pulse wave signal or the differentiated signal filtered by the first filter into sections such that each section includes one of the extracted characteristic points. The partitioned sections are overlapped such that the characteristic points are coincident with each other, and arithmetically averaged.

Abstract: A pulse wave sensor is to detect a pulse wave signal from a measurement target finger, which is a part of fingers of a subject. A placement table is to enable a palm of the subject to be placed thereon. A blood pressure measurement unit is to measure a blood pressure based on the pulse wave signal detected with the pulse wave sensor. An upper surface of the placement table includes a palm placement region that has a shape, which is convex upward with respect to a longitudinal direction of the palm and is inclined to lower on a side of a little finger in a lateral direction of the palm.

Abstract: A pulse wave measuring device includes a light emitter unit, a light receiver unit, a pulse wave measuring unit and a contact portion. The light receiver unit receives reflected light, which is reflected from a finger after transmission of the light from the light emitter unit. The pulse wave measuring unit measures a pulse wave based on the reflected light, which is received with the light receiver unit. The finger contacts the contact portion at a time of measuring the pulse wave. The contact portion has a recess, which receives at least a portion of the finger at the time of measuring the pulse wave, and a protrusion is provided in an inside of the recess.

Abstract: A sphygmomanometer includes an operation part, a pulse wave sensor that detects a pulse wave signal indicative of a pulse wave in a part of the patient body that is operating the operation part. A first manometer measures a blood pressure based on the pulse wave signal, and a second manometer measures the blood pressure with a cuff that is worn by the patient. A cuff wearing detector detects a wearing of the cuff by the patient. A controller measures the blood pressure with the first manometer when the operation part is operated long enough for a detection of the pulse wave signal and measures the blood pressure with the second manometer when the cuff wearing detector detects that the cuff is worn and that the operation part is being operated.
