A calibration device is equipped with a sphygmomanometer connected to an air hose and a communication cable and aims to calibrate the output value of the pressure sensor in the calibration unit based on a difference between the applied pressure and the internal pressure.
Abstract
A calibration device (8) is equipped with a sphygmomanometer (1) connected to an air hose (10) and a communication cable (11). If a connection is detected, the calibration apparatus includes a valve (22) of the sphygmomanometer and its valve (812) and applies pressure to the air hose in order to measure the pressure, and determines the air leakage of the sphygmomanometer based on the pressure change with a loss of air determination unit (802). The calibration device causes a pressure sensor (23) of the sphygmomanometer measures the internal pressure and receives the measurement result to the communication I / F (815), and the result of the device deviation tests of the sphygmomanometer determined based on a difference between the applied pressure and the internal pressure with a device deviation determination unit (804). If it is determined that the device deviation test fails, a control signal is output to the sphygmomanometer to calibrate the output value of the pressure sensor in the calibration unit (805).
