Claims

[Claim for Utility Model Registration] A pressurization system including an arm cuff, a pressurizing means, and an evacuation means, a cuff pressure detecting means, a blood flow sound detecting means, and the output signals from these detecting means to detect systolic blood pressure and A blood pressure measuring device comprising: a blood pressure determination means for measuring diastolic blood pressure; a timer means activated each time a blood flow sound is detected by the blood flow sound detection means; a first cuff pressure storage means for storing or updating the output of the cuff pressure detection means; a second cuff pressure storage means for storing the output of the cuff pressure detection means when the timer means times out; means for calculating a difference in cuff pressure between the pressure storage means and the second cuff pressure storage means; a comparison means for comparing the difference value calculated by the calculation means with a predetermined value;
and means for outputting an exhaust error when the difference value is greater than a predetermined value.
