<p>PROBLEM TO BE SOLVED: To improve noise proof property by continuously measuring pressure in a vein by means of the plural sensor elements of a tonometry-type blood pressure sensor, detecting pressure in a cuff in the pressure reducing process of the cuff and deciding a max. blood pressure value and a min. blood pressure value, etc., for every pulse. SOLUTION: When blood pressure is measured, the tonometry-type blood pressure sensor 1 is fitted to a wrist, the cuff 5 is fitted to an upper arm part and, after that, a start switch 22 is depressed. Then, an air pump 23 is operated and air is injected to the air pressure room of the blood pressure sensor 1. At the point of time when air pressure becomes the set one, a pulse phenomenon is detected by the blood pressure sensor 1, respective kinds of measurement data are compared by a processing part 21, the sensor element being excellent in a measurement state is selected and max. blood pressure and min. blood pressure for every pulse and a pulse rate, etc., are decided based on measurement data measured by the element. After that, air inside the air pressure room is discharged and a proofreading processing is executed from the output of a pressure sensor 7 when a proofreading processing time elapses.</p> |
