20110295130 | BLOOD PRESSURE MEASUREMENT DEVICE INCLUDING CUFF TO BE WRAPPED AROUND MEASUREMENT SITE - 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 ΔV | 12-01-2011 |
20120143069 | ELECTRONIC SPHYGMOMANOMETER THAT CAN CONFIRM AIR LEAKAGE - In an electronic sphygmomanometer, a CPU inlets air into a closed space, including an air bladder in an arm band, an air tube, and another air tube up to a predetermined pressure using a pump, maintains the closed space in a closed state for a certain time, and monitors a decrease in pressure within the maintained time using a pressure sensor. A determination that the air leakage is generated in the closed space including the air bladder and the air tubes is made when the pressure is decreased lower than an allowable amount or more. Similarly, the inspection is also performed to a closed space including the other air tube. The CPU determines whether the air leakage is generated and determines whether an air leakage point exists in the space including the air bladder and the air tube or the space including the other air tube. | 06-07-2012 |
20120165687 | SPHYGMOMANOMETER - A blood pressure measurement device includes a sensor that detects a change of an internal pressure of an air bladder during the inflation and/or deflation of the air bladder. The sensor further includes a first sensor and a second sensor, which each have a diaphragm connected to the air bladder. A face of each of the diaphragms of the first sensor and the second sensor is flexibly displaced in accordance with the change of the internal pressure of the air bladder. The face of the diaphragm of the second sensor is arranged in a different position and/or direction from the face of the diaphragm of the first sensor. A central processing unit of the device includes a failure judgment unit that determines whether there was any failure with the sensor based on difference between the internal pressures detected by the first sensor and the second sensor. | 06-28-2012 |
20120203119 | ELECTRONIC SPHYGMOMANOMETER - An electronic sphygmomanometer includes a cuff that can be worn at a measurement site, a pressure adjustment unit that adjusts the pressure applied inside the cuff; a pressure detection unit that includes multiple pressure sensors and that detects the cuff pressure inside the cuff based on pressure information output from the pressure sensors, a blood pressure calculation unit that calculates a blood pressure based on change in the cuff pressure detected by the pressure detection unit during blood pressure measurement, a keeping unit that keeps the cuff pressure at a predetermined pressure using the pressure adjustment unit during blood pressure measurement, and a sensor abnormality detection unit that, in a state in which the keeping unit keeps the cuff pressure at the predetermined pressure, detects whether an abnormality has occurred in the pressure sensors based on the pressure information output from the pressure sensors. | 08-09-2012 |
20120232412 | BLOOD PRESSURE MEASUREMENT DEVICE, CONTROL METHOD OF ELECTRONIC SPHYGMOMANOMETER AND CONTROL PROGRAM OF ELECTRONIC SPHYGMOMANOMETER - A sphygmomanometer, in a deflation process after inflation to prescribed pressure adjusts a drive voltage of an exhaust valve such that a deflation speed of a fluid bag achieves a prescribed deflation speed during an adjustment period, which is a prescribed period after starting deflation. When the adjustment period ends or when the deflation speed of the fluid bag achieves the prescribed speed, control is subsequently performed to fix the drive voltage of the exhaust valve and deflate the fluid bag while holding a gap of the exhaust valve constant. | 09-13-2012 |
20130030310 | BLOOD PRESSURE MEASUREMENT DEVICE - A cuff of a blood pressure measurement device compresses a measurement site by being wrapped therearound. A control unit evaluates the wrapping strength of the cuff, by comparing a detection amount detected based on the output of a sensor with a history of the detection amount stored in the storage unit. | 01-31-2013 |
20130030311 | BLOOD PRESSURE MEASUREMENT DEVICE - A blood pressure measurement device compresses a measurement site by a cuff being wrapped around the measurement site. A first fluid bag is provided inside an outer package of the cuff. An indicating member is provided in the cuff so as to contact the outer package and the first fluid bag. The properties of the indicating member change in a visible manner in accordance with a magnitude of a force with which the indicating member is pressed by the outer package and the first fluid bag. | 01-31-2013 |
