SPHYGMOMANOMETER

PURPOSE:To make it possible to measure a precise value of blood pressure by making it possible for a measured person to select an exercise condition, a bodily-feeled temp. etc., by means of selection keys and making an objective correction of the value of blood pressure possible based on this selection and the fuzzy estimation. CONSTITUTION:An exercise condition when a blood pressure is measured is selected from three kinds of selection keys, namely keys of no exercise, just after light exercise and just after heavy exercise at a selection part 2 for the exercise condition and a bodily-feeled temp. when the blood pressure is measured is selected from three kinds of selection keys, namely keys of normal, a little cold, cold at a selection part 4 for the bodily-feeled temp. On the other hand, the blood pressure is actually measured at a blood pressure measuring part 12 by outputting a sensor signal corresponding to the blood pressure on an arm by means of a blood pressure sensor 6 provided on an arm belt 10 fitted on an arm 8 of a human body. Then, each selected data is output to a fuzzy estimation part 14 to estimate a corrected data for the value of the blood pressure based on a fuzzy rule. Then, this corrected data for the value of the blood pressure and the measured value of the blood pressure are input in a blood pressure correcting part 16 and the obtd. corrected value of the blood pressure is displayed at a displaying part 18.
