BODY IMPLANTABLE DEVICE WHICH CAN SET PRIORITY ORDERING OF DIAGNOSTIC DATA AND WHICH CAN ALLOCATE MEMORY

摘要

PROBLEM TO BE SOLVED: To obtain important date to be traced at an optional time by selecting date which are clinically important among data collected from a specific number of physiological sensors, and by overwriting the same over low important data in memory. SOLUTION: A CPU 36 is composed of a microprocessor which can carry out multi-task monitor operation and diagnosing operation. Date from at least one physiological sensor is compared with an expectable data range so as to determine whether the event is clinically important or not. When a threshold vent is generated as a result of the detemnination, the date is stored in memory. Accordingly, whether this memory 34 is usable or not is determined, and if it is usable, the data is stored. If is not unusable, the priority value of the data is compared with each of relative values of various segments stored in memory 34 for determination. If the priority value of data to be stored is higher, the data is overwritten on the data in the memory 34. With this arrangement, the data a doctor considers to be important is stored, and can be traced.
