Connection monitoring circuit has alarm signal circuit connected to constant current generator that produces alarm signal to indicate degradation of monitor/patient connection

摘要

The device has a constant current generator (Q1) for providing a constant current output and an isolating transformer (T1) with a primary winding (34) connected to the constant current generator to receive the constant current output and a secondary winding (30) for connection to the patient (12). An alarm signal circuit connected to the constant current generator produces an alarm signal to indicate degradation of the connection. An Independent claim is also included for a patient monitor.
