Method for measuring blood pressure and a blood-pressure measuring device for carrying out the method
First Claim
1. A method for measuring blood pressure by the use of a blood pressure cuff and a pressure gauge connected to said cuff, said method including the steps of:
- placing said cuff around a limb of a patient to obtain a pressure-level value from said pressure gauge,determining a pulse frequency value of the patient'"'"'s pulse,providing a connection unit connected to said pressure gauge, said correction unit being operable to make corrections in said pressure level for blood-pressure measuring errors occurring as a function of pulse frequency, pressure level, patient sex, patient age, and limb circumference,supplying said pressure level value and said pulse frequency value to said correction unit, and causing said correction unit to make corrections for said errors occurring as a function of said pulse frequency value and said pressure level value,providing an infeed unit connected to said correction unit, said infeed unit being operable to supply to said correction unit data corresponding to patient sex, patient age, and limb circumference,actuating said infeed unit to supply said data to said correction unit, and causing said correction unit to make corrections for errors occurring as a function of the patient sex, patient age, and limb circumference, andproviding a display unit connected to said correction unit, and causing said display unit to display a blood-pressure level value corrected for errors occurring as a function of pulse frequency value, pressure level value, patient sex, patient age, and limb circumference.

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.
