Abstract

A patient monitoring/signal processing module with increased electrical isolation is disclosed. The combination of an inner isolation piece and an isolation film provide signal isolation and electrical over-voltage protection between a lower, isolated portion of the unit defined by a lower housing and the isolation piece and an upper, non-isolated portion of the unit, defined by an upper housing and the isolation piece, increasing the module's ability to survive an over-voltage condition without damage to itself or to the patient to whom it is coupled. The combination of the isolation film and the isolation piece results in a much thinner module than would otherwise have been necessary to achieve the same levels of signal and electrical isolation.
