20110015531 | ELECTRONIC BLOOD PRESSURE GAUGE FOR MEASURING BLOOD PRESSURE BY USING VOLUME COMPENSATION METHOD - An electronic sphygmomanometer, which measures blood pressure in accordance with the volume compensation method, detects a cuff pressure inside a cuff attached to a measurement site of the blood pressure. An arterial volume detection circuit detects an arterial volume signal of the measurement site. A drive control unit, after setting the cuff pressure to an initial cuff pressure, servo-controls a cuff pressure adjustment unit so that a volume of an artery becomes constant, based on the detected arterial volume signal. While the servo control is being performed, an arterial volume change amount is detected based on the detected arterial volume signal. In the servo control, when it is detected that the change amount in the arterial volume is minimal, a volume change elimination rate calculating unit calculates a volume change elimination rate (an amplitude of the arterial volume signal during the control/an amplitude of the arterial volume signal before the control) to output the same as a barometer of arteriosclerosis. | 01-20-2011 |
20110208069 | BLOOD PRESSURE INFORMATION MEASUREMENT DEVICE - A blood pressure information measurement device instantaneously changes cuff pressure in a specified pressure section in order to detect a control target value in artery volume constant control. An artery volume signal is detected in that period, and an inflection point of the detected artery volume signal is detected by performing differentiation processing or the like. The inflection point of the detected artery volume signal is fixed as the control target value. | 08-25-2011 |
20110224558 | BLOOD PRESSURE INFORMATION MEASUREMENT DEVICE FOR MEASURING PULSE WAVE PROPAGATION SPEED AS BLOOD PRESSURE INFORMATION - In the measurement device, the blood pressure of the upper arm and the blood pressure of the lower limb are measured using cuffs attached to the upper arm and the lower limb (ankle), respectively. The pulse wave of the upper arm and the pulse wave of the lower limb are measured in synchronization using such cuffs. The upper arm-lower limb pulse wave propagation velocity (baPWV) is calculated based on the appearance time difference of the two pulse waves. The upper arm pulse wave propagation velocity (upper arm PWV) is calculated based on the appearance time difference of the ejection wave and the reflection wave in the upper arm pulse wave. If the values of such propagation velocities are different, a warning is issued. | 09-15-2011 |
20110282224 | PULSE WAVE ANALYZER AND PULSE WAVE ANALYZING METHOD - In a pulse wave analyzer, a local maximum point of a fourth order differentiated wave of the pulse wave of one beat is acquired, and a maximum point of a reflection wave of the local maximum points of the fourth order differentiation existing in a zone of an original waveform is determined as a starting point of a reflection wave zone that is a first characteristic point. With 10% of the amplitude of the first characteristic as a threshold value, a time point at which the amplitude reaches the threshold value after the relevant point is determined as an ending point of the reflection wave zone that is a second characteristic point. The duration time of the reflection time of the time between the first characteristic point and the second characteristic point is calculated as an index useful in the diagnosis of heart disease. | 11-17-2011 |
20120071768 | BLOOD PRESSURE INFORMATION MEASUREMENT DEVICE - A blood pressure information measurement device includes light emitting elements and light receiving elements as a plurality of pairs of first and second sensors in a cuff. While the cuff pressure is increased, combinations of the plurality of pairs of the light emitting elements and the light receiving elements are switched, and volume pulse waves are obtained from each of the combinations. After increasing the cuff pressure, for each of the volume pulse waves corresponding to the combinations, a specific volume value at a point where the amount of volume change becomes maximal is extracted. Thereafter, based on values corresponding to the maximum and minimum blood pressure and the specific volume value, the sensors for measurement are determined. | 03-22-2012 |
20120172734 | BLOOD PRESSURE MANOMETER AND A METHOD OF CALCULATING INDICES OF ATHEROSCLEROSIS USING THE BLOOD PRESSURE MANOMETER - A blood pressure measurement device accurately calculates an index useful in determining the degree of arteriosclerosis by accurately detecting a difference in time of appearance of a ejection wave and reflected wave in a blood pressure waveform. The device sets a threshold value based on an index that expresses a characteristic of the blood pressure waveform with respect to the point of appearance of the reflected wave in the blood pressure and estimates a rise point of the reflected wave by calculating an x-coordinate value of a point based on a maximum amplitude of the reflected wave and the threshold value. The device obtains the index of degree of arteriosclerosis by calculating a time difference in appearance between the ejection wave and the reflected wave based on the estimated rise point of the reflected wave. | 07-05-2012 |
