Body worn physiological sensor device having a disposable electrode module

A body worn patient monitoring device comprising:

• a disposable module including a plurality of electrical connections, said electrical connections adapted to be couplable to a skin surface to measure physiological signals, at least one of said electrical connections comprising a half cell, the disposable module including a disposable module connector;
• a power source to power the body worn patient monitoring device;
• a communication-computation module being removable and reusable, having a communication-computation module connector to receive physiological signals from the disposable module via said disposable module connector, the communication-computation module including:
• a microprocessor to actively monitor the patient and to perform a real-time physiological analysis of the physiological signals, said analysis determining an occurrence of a predetermined physiological event, and
• a radio circuit to communicate, upon determination of the predetermined physiological event, a result of the physiological analysis on the occurrence of the predetermined physiological event, via a radio transmission to a remote radio receiver, wherein the disposable module is mechanically and electrically coupled directly to the communication-computation module and the body worn patient monitoring device including the disposable module and the communication-computation module is adapted to be directly non-permanently affixed to the skin surface of the patient;
• and
• at least one series current-limiting resistor configured to protect the communication-computation module, the at least one series current-limiting resistor being screened on a flexible substrate, the at least one series current-limiting resistor being in the form of resistive traces.
