MEDICAL DEVICE AND METHOD FOR CONTROLLING SAME

摘要

A medical device has a first controller that has a control section responsible for sequence control of a device and is for controlling the medical device, a second controller that operates if a failure occurs in the first controller, and an alarm that makes a notification output based on exclusive OR between notification outputs of the first controller and the second controller. The second controller, after acquiring the notification output of the first controller, outputs its own notification output as it is if the notification output of the first controller is in an OFF state, or inverts its own notification output so as to output an inversion result if the notification output of the first controller is in an ON state.

主权项

1. A medical device comprising:
a first controller that has a control section responsible for sequence control of the medical device, wherein the first controller generates a first notification signal corresponding to detection of a failure in the first controller; a second controller responsible for sequence control of the medical device if a failure occurs in the first controller, wherein the second controller generates a second notification signal corresponding to detection of a failure in the second controller; and an alarm indicator that makes a notification output based on exclusive OR between the first and second notification signals, wherein the second controller receives the first notification signal and generates its second notification signal unchanged if the first notification signal is in an OFF state, or inverts its second notification signal if the first notification signal is in an ON state.
