20090312651ELECTRONIC BLOOD PRESSURE MEASUREMENT DEVICE CALCULATING BLOOD PRESSURE VALUE - A blood pressure measurement bladder (12-17-2009
20110152700ELECTRONIC SPHYGMOMANOMETER FOR ENHANCING RELIABILITY OF MEASUREMENT VALUE - An electronic sphygmomanometer has a cuff to be attached to a measurement site, a pressurization/depressurization unit for adjusting a pressure to be applied to the cuff, a pressure detection unit including a plurality of pressure sensors, for detecting cuff pressures in the cuff based on pressure information output from the plurality of pressure sensors, and a blood pressure calculating unit for calculating a blood pressure based on a change in the cuff pressures detected by the pressure detection unit. Blood pressure measurement and detection of abnormality on the plurality of pressure sensors are carried out based on the cuff pressures respectively corresponding to the plurality of pressure sensors detected according to the pieces of pressure information output from the plurality of pressure sensors.06-23-2011
20110208069BLOOD 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
20110208070BLOOD PRESSURE INFORMATION MEASUREMENT DEVICE - During a period of servo control, an artery volume of a peripheral site is detected by an artery volume sensor arranged at a peripheral site (site on the peripheral side than a measurement site) of a person to be measured. If an amount of change in the artery volume of the peripheral site or a value of the artery volume is greater than or equal to a predetermined ratio of a reference value at the beginning of the measurement, the servo control and a blood pressure determination process are continued. When detected thereafter that the amount of change in the artery volume of the peripheral site or the value of the artery volume is smaller than the predetermined ratio of the reference value at the beginning of the measurement, the measurement is stopped at the relevant time point.08-25-2011
20110245695ELECTRONIC SPHYGMOMANOMETER - An electronic sphygmomanometer includes a pressure control unit configured to conduct pressurization control on a cuff (pressure control toward a specific direction) and acquire a cuff pressure signal at a time of the pressurization control to thereby measure a pressure pulse wave; a displacement decision unit configured to decide whether displacement has occurred between a position of the cuff and a virtual position of the heart based on an output from an angle sensor when the pressurization control is being conducted; and a return processing unit configured to, when it is decided that displacement has occurred, stop the pressurization control and conduct depressurization control on the cuff to thereby return an intra-cuff pressure to a specific pressure value that denotes a pressure value before the occurrence of the displacement. The pressure control unit resumes the pressurization control after processing by the return processing unit.10-06-2011
20110251499ELECTRONIC SPHYGMOMANOMETER - An electronic sphygmomanometer has a causing unit that causes a constant volume change in a cuff and a causing processing unit for controlling a drive of the causing unit for a period for which a first pressure control (for example, depressurization control) is made so as to execute a process for giving a constant volume change to the cuff. Further, the electronic sphygmomanometer includes a measurement control unit that controls based on a cuff pressure signal measurement of a pulse wave amplitude and a pressure change property with respect to the volume change. The electronic sphygmomanometer includes a correction processing unit that corrects the measured pulse wave amplitude based on the measured pressure change property and a blood pressure calculating unit that calculates a blood pressure value based on the corrected pulse wave amplitude.10-13-2011
20110251500ELECTRONIC SPHYGMOMANOMETER AND BLOOD PRESSURE MEASUREMENT METHOD - An electronic sphygmomanometer includes a cuff to be attached to a blood pressure measurement site, a pump and a valve for adjusting a pressure to apply on the cuff, a pressure sensor for detecting the pressure of the cuff, a central processing unit (CPU) for calculating a blood pressure value from the cuff pressure, a memory for recording the blood pressure value, and an operation unit for performing a blood pressure measurement. Further, the CPU acquires information on an application voltage of the valve or the pump at a time of blood pressure measurement, and the information on the application voltage is stored in the memory. The CPU corrects the application voltage so that control of the valve or the pump is carried out based on the application voltage stored in the memory.10-13-2011
20110251501ELECTRONIC SPHYGMOMANOMETER AND BLOOD PRESSURE MEASUREMENT METHOD - An electronic sphygmomanometer includes a cuff to be attached to a blood pressure measurement site, a pump and a valve for adjusting a pressure to be applied on the cuff, a pressure sensor for detecting the pressure in the cuff, a central processing unit (CPU) for calculating a blood pressure value from the cuff pressure, a memory for recording the blood pressure value, and an operation unit for carrying out a blood pressure measurement. The CPU corrects the blood pressure value based on separately acquired correction information and acquires information on a quality of the measurement site as the correction information. When the information on the quality of the measurement site is acquired as the correction information, the CPU corrects the blood pressure calculation parameter based on the information on the quality of the measurement site.10-13-2011
