  • Publication number: 20170224226
    Abstract: The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

  • Patent number: 9364156
    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.

  • Publication number: 20150182138
    Abstract: A blood pressure information measurement cuff includes a band-shaped cuff body and a fluid bladder that is connected to the cuff body and is configured to expand/contract with insertion or discharge of a fluid, the blood pressuring information measurement cuff being configured to be used while wrapped around a body being examined. The fluid bladder is formed into a rectangular bag shape by flattening a tube-shaped resin sheet and sealing the two end portions thereof that form openings. A partial welded portion, which is formed by the resin sheet being folded so as to overlap itself and welded, is formed on at least a portion of one of a pair of opposing sides that intersect the sides of the two sealed end portions and extend in a wrapping direction on the body being examined.

  • Patent number: 8808189
    Abstract: A blood pressure measurement device includes a wrapping strength detecting portion for detecting a wrapping strength of a cuff with respect to a measurement site. The wrapping strength detecting portion detects the wrapping strength of the cuff prior to calculation of a blood pressure value by a blood pressure calculation unit. That is, the wrapping strength of the cuff is detected based on a relationship indicated by a volume change ?V12 of the cuff detected with a change in the detection pressure in the cuff wrapped around the measurement site from P1 to P2 and a volume change ?23 of the cuff detected with change from P2 to P3 in a process of controlling the cuff pressure by a pressure adjustment unit.

  • Patent number: 8715197
    Abstract: 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.

  • Patent number: 8568328
    Abstract: 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.

  • Publication number: 20130190576
    Abstract: 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.

  • Publication number: 20120071768
    Abstract: 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.
