METHOD FOR TESTING FUNCTION OF DISPLAY DEVICE FOR MEDICAL CARE TECHNIQUE EQUIPMENT, AND THE EQUIPMENT PROVIDED WITH DISPLAY DEVICE AND ALARM SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the indication of a functional defect in medical care technique equipment. SOLUTION: At least a part of a display device is driven by a reference signal. When a function is normal, a response signal depending on the reference signal is outputted from the display device when driving it with the reference signal. Then, the generation of the response signal is monitored by using a sensor. When the signal is not sensed or a signal different from a predicted response signal is sensed by the sensor, the abnormality of the function of the display device is identified.
