Abstract

This demonstration presents our NASS (Network Aware Supervisory System) framework prototype for medical device integration systems. The NASS framework interconnects medical devices over wireless for convenience, seamlessness and sanitation, and provides safety-guaranteed supervision. Our prototype was developed in Sun Java Real-time Environment. Real-time Java provides well-formed convenience of dynamically loading and unloading medical application logic and safety rules on the fly in real-time environments. To tackle the complexity of using real-time Java in the safety-critical system, we also applied HW/SW codesign method. Real-time Java Environment Linux operating system may not be robust enough for medical devices to fully rely on. In our prototype, the supervisor software in Java performs all logical decisions including contingency plan generation derived from the safety rules. Once logic is decided, the decisions and plans for the devices are delivered to the hardware implemented in FPGA at each device to physically drive medical equipments. Since the execution of decisions and plans are delegated to the hardware, any failure in software does not harm the integrated safety. Our demonstration shows how safety is managed in different kinds of failures from wireless network failures to device software failures.
