Failure prediction system of ultrasonic endoscope apparatus, failure prediction method of ultrasonic endoscope apparatus, and failure prediction program of ultrasonic endoscope apparatus

A non-transitory computer readable recording medium storing a failure prediction program of an ultrasonic endoscope apparatus including a monitor and an ultrasonic endoscope having a plurality of ultrasonic vibrators arranged in a convexly curved shape and a plurality of electrodes respectively connected to each of the plurality of ultrasonic vibrators, wherein the plurality of electrodes are connected to a flexible printed circuit and a plurality of coaxial cables, for causing a computer to execute:

• a transmitting step of controlling the plurality of ultrasonic vibrators to sequentially transmit ultrasonic waves respectively from each of the plurality of ultrasonic vibrators;
• an abnormality detection step of acquiring a plurality of reception signals of reflected waves of ultrasonic waves from the plurality of ultrasonic vibrators and detecting an abnormality of the ultrasonic endoscope apparatus based on the plurality of the reception signals;
• a storage control step of storing information on the abnormality detected in the abnormality detection step in association with time information;
• a failure prediction step of predicting a failure timing of the ultrasonic endoscope apparatus based on a plurality of pieces of the information on the abnormality stored in the storage control step and the time information corresponding to the plurality of pieces of the information on the abnormality, the failure timing being a date when an abnormality occurrence number will reach a predetermined threshold in future;
• and
• a notification step of maintaining the ultrasonic endoscope by displaying a message indicating a recommended maintenance timing of the ultrasonic endoscope based on the predicted failure timing on the monitor to notify a user of the recommended maintenance timing.
