Operation of medical devices during startup and shutdown

摘要

The medical device comprises a software (SW) system executed by a processor. A SW system defines a plurality of subsystems including a primary subsystem and one or more secondary subsystems, each of which comprises a SW application involved in the operation of a medical device during a medical procedure. A deterministic and decentralized boot of the SW system uses two different notifications to prepare the boot procedure for booting at the subsystem level and for the primary subsystem to coordinate the booting of the subsystem at the system level. It is possible by separating into preparation. The method is to start each SW application (401) and to provide an "application ready" notification by each SW application in each of the secondary subsystems when it is ready to launch (402). ), When all of the SW applications provide the "Application Ready" notification, each of the secondary subsystems will provide the "Subsystem Ready" notification (403), the "Subsystem Ready" notification. (405) is included when the primary subsystem adjusts the boot of the subsystem when it receives. [Selection diagram] FIG. 4A
