Abstract
A blood pressure measuring device includes a cuff (1) intended to be placed around the upper arm or the thigh of a person, a pressure sensor (2) and a manometer (3). The values measured by the cuff are automatically corrected in a correction unit (4), so as to eliminate systematic errors contingent on the pulse frequency and the pressure level prevailing at the moment of measuring blood pressure. The device also includes an infeed unit (6) into which data relating to the person's age, sex and arm circumference is inserted. The correction unit (4) then uses this data to correct the values measured by the cuff, so that systematic errors contingent on age, sex and arm circumference will be eliminated. The corrective values of the systolic and diastolic pressure are then displayed on a display unit (8), these pressure values being independent of the person's age, sex, arm circumference, pulse frequency and pressure level.
