Abstract: A CPU acquires factor information for a degree of arteriosclerosis, stores a plurality of pseudo blood flow waveforms, generates a waveform estimated as a blood flow waveform by compositing the plurality of pseudo blood flow waveforms based on the factor information, decomposes a pulse waveform into waveforms of an ejected wave and a reflected wave using the pulse waveform and the waveform estimated as the blood flow waveform, and calculates an index of the degree of arteriosclerosis from a relationship between the ejected wave and the reflected wave obtained by decomposing the pulse waveform.

Abstract: The invention provides an electric toothbrush capable of changing a resonant frequency and vibration amplitude of an eccentric shaft. An electric toothbrush of the present invention includes a motor, an eccentric shaft with one end fixed to a rotation shaft of the motor, and a stemserving as a vibration transmitting component having a bearing for supporting the other end of the eccentric shaft for transmitting vibration generated in accordance with rotation of the eccentric shaft to a brush portion. In the electric toothbrush, the eccentric shaft is formed so that a gravity center position is movable at least in one direction among a direction in which a distance to a shaft center is changed and an axial direction.

The trunk area dimension measurement unit has a frame shape that can be disposed surrounding the measurement subject's trunk area, and includes a base portion whose position relative to the trunk area does not change in a state where the trunk area dimension measurement unit is disposed surrounding the trunk area, and a mobile portion that is attached in a movable state to the base portion and whose position relative to the trunk area can change in a state where the trunk area dimension measurement unit is disposed surrounding the trunk area. The trunk area dimension detection unit includes at least a non-contact range sensor provided in the mobile portion.

Abstract: A first calculation unit receives phase characteristics Pa(f) and Pb(f) outputted from frequency transform units, calculates a propagation time difference based on a phase difference between the two phase characteristics in a high-frequency component thereof, and calculates a pulse wave velocity by dividing a difference in the distances of vascular pathways from the heart to respective measurement areas. Meanwhile, a second calculation unit calculates a pulse wave velocity by dividing the stated difference in the distances by a appearance time difference at a predetermined position in respective pulse waveforms obtained by rendering the measurement signals Pa(t) and Pb(t) on a time axis. A comparison unit compares the pulse wave velocities, and in the case where the ratio thereof is outside a predetermined range, an evaluation result indicating that it is possible that a predetermined pathologic change is present in the vascular pathway is outputted to a display processing unit.

Abstract: A blood pressure measurement device includes a cuff, inflation/deflation unit, pressure detection unit, volume detection unit, and control unit. The control unit determines values of an arterial volume signal detected by the volume detection unit, changes a prescribed control target value from the determined value at a time of diastolic blood pressure to a vicinity of the value at the time of systolic blood pressure during a rise time, changes the prescribed control target value from the determined value at the time of systolic blood pressure to a vicinity of the value at the time of diastolic pressure during a fall time, and adjusts the pressure of the cuff by controlling the inflation/deflation unit such that the volume indicated by the arterial volume signal detected by the volume detection unit matches the prescribed control target value. Thus, by applying a control target value, blood pressure can be measured.

Abstract: Every pulse wave, a constant volume control unit performs servo control while updating a servo gain such that a difference between an arterial volume shown by an arterial volume signal that is detected by an arterial volume detection circuit and a control target value of the servo control is less than a control deviation at which a rate of change of the arterial volume relative to a change in cuff pressure is deemed to be constant. Because the control deviation is the difference between the arterial volume shown by the arterial volume signal and the control target value, a blood pressure decision unit decides, as a blood pressure, the cuff pressure sequentially detected in a period during which servo control is performed, by correcting the cuff pressure using the control deviation and the rate of change deemed to be constant.
