Abstract

A blood pressure measuring system includes: a sphygmomanometer which is configured to invasively measure a blood pressure value of a subject; a calibrating section which is configured to calibrate a measurement reference value of the blood pressure value; a first atmospheric pressure sensor which is adapted to be attached to the subject; a second atmospheric pressure sensor which is fixed to a predetermined position; a difference acquiring section which is configured to acquire a difference between a first atmospheric pressure value detected by the first atmospheric pressure sensor, and a second atmospheric pressure value detected by the second atmospheric pressure sensor; and a determining section which, based on the difference, is configured to determine whether a calibration of the measurement reference value is necessary or not.

Claims

1. A blood pressure measuring system comprising:

a sphygmomanometer which is configured to invasively measure a blood pressure value of a subject;

a calibrating section which is configured to calibrate a measurement reference value of the blood pressure value;

a first atmospheric pressure sensor which is adapted to be attached to the subject;

a second atmospheric pressure sensor which is fixed to a predetermined position;

a difference acquiring section which is configured to acquire a difference between a first atmospheric pressure value detected by the first atmospheric pressure sensor, and a second atmospheric pressure value detected by the second atmospheric pressure sensor; and

a determining section which, based on the difference, is configured to determine whether a calibration of the measurement reference value is necessary or not.

2. The blood pressure measuring system according to claim 1, wherein, when the determining section determines that the calibration is necessary, the calibrating section automatically calibrates the measurement reference value.

3. The blood pressure measuring system according to claim 1, further comprising:

a notifying section which, when the determining section determines that the calibration is necessary, is configured to output an alarm.

4. The blood pressure measuring system according to claim 1, further comprising:

a temperature sensor which is disposed in adjacent to at least one of the first atmospheric pressure sensor and the second atmospheric pressure sensor, wherein, based on the difference and a temperature detected by the temperature sensor, the determining section determines whether the calibration is necessary or not.

5. The blood pressure measuring system according to claim 1, wherein the first atmospheric pressure sensor is adapted to be attached to a chest of the subject.

6. The blood pressure measuring system according to claim 1, wherein the determining section determines that the calibration of the measurement reference value is necessary when a value of the difference between the first and second atmospheric pressure values is varied at a degree which is larger than a predetermined value.

7. The blood pressure measuring system according to claim 1, the calibrating section stores a relationship between a correction amount of the measurement reference value and a value of the difference between the first and second atmospheric pressure values.
