First Claim
Patent Images
1. A self-contained wrist-type blood pressure monitor comprising:
- (i) an inflatable cuff adapted to be placed around the wrist of a patient;
(ii) a pressure sensor for measuring the pressure within said cuff;
(iii) a calculating arrangement for calculating diastolic and systolic blood pressure values based on pressure values measured within said cuff, which has an editable memory provided with calibration data such as calibration data to be used in the calculation process of the calculation arrangement;
(iv) an interface connector being connectable to the interface connector of a calibrating device for calibration of the wrist type blood pressure monitor, whereby calibration data provided by the calibration device is storable in the editable memory of the calculation arrangement.

Abstract
A wrist type bloodpressure monitor (1) is provided with an interface connector (16) for calibration purposes. The correct values of the blood pressure are measured with a calibration device (20) including an upper arm blood pressure measuring monitor (11). The values (D′, S′) measured in this way are used to recalibrate the wrist type blood pressure monitor (1). The wrist type blood pressure monitor (1) is therefore provided with an editable memory (5) for the purpose of recalibration.

9. A method for calibrating a self-contained wrist type blood pressure monitor having an inflatable cuff adapted to be placed around the wrist of a patient and to determine the diastolic and the systolic blood pressure of the patient, said method comprising the steps of:
-
a) measuring the patient'"'"'s blood pressure with the wrist type blood pressure monitor to be calibrated;
b) before or after step a), coupling the wrist type blood pressure monitor and an upper arm blood pressure monitor together via respective interface connectors;
c) measuring the blood pressure with the upper arm pressure monitor;
d) comparing the blood pressure values obtained in steps a) and b);
e) depending on the results of step d), recalibrating the wrist type blood pressure monitor, if necessary; and
f) after step c), d) or e), uncoupling the wrist type blood pressure monitor from the upper arm blood pressure monitor. - View Dependent Claims (10, 11, 12, 13, 14)
