Abstract
A sensor adapter cable provides medical personnel with the convenience of utilizing otherwise incompatible optical sensors with multiple blood parameter plug-ins to a physiological monitor, where the plug-ins each have keyed connectors that mechanically lock-out incompatible sensors in addition readers that poll sensor identification components in each sensor so as to electrically lock-out incompatible sensors.

A sensor adapter cable provides medical personnel with the convenience of utilizing otherwise incompatible optical sensors with multiple blood parameter plug-ins to a physiological monitor, where the plug-ins each have keyed connectors that mechanically lock-out incompatible sensors in addition to readers that poll sensor identification components in each sensor so as to electrically lock-out incompatible sensors, the sensor adapter cable comprising:
- a sensor connector that mechanically connects to a predetermined sensor and electrically communicates with a plurality of sensor electrical elements within the predetermined sensor;
- a plug-in connector that mechanically connects to a predetermined plug-in and electrically communicates with a plurality of plug-in electrical elements within the predetermined plug-in;
- an interconnection cable that mechanically attaches between and provides electrical communications between the sensor connector and the plug-in connector;
- and
- a pod, including a circuit, incorporated within the interconnecting cable that electrically interfaces the sensor connector to the plug-in connector, the pod including both active and passive sensor identification elements;
- wherein the circuit automatically switches between using one of the active or passive sensor identification elements to communicate across at least one common pin of a plurality of pins and using the other of the active or passive sensor identification elements to communicate across the at least one common pin based on a monitoring system type the sensor adapter cable is connected with.
A sensor adapter cable manufacturing method comprising:
- providing an interface cable having a sensor connector on a first end and a plug-in connector on a second end;
- incorporating a plurality of resistive and memory IDs within the cable;
- and
- attaching a circuit board to the cable configured to automatically select a particular one of an ID to present to the plug-in connector in response to a read signal asserted at the plug-in connector;
- wherein the circuit board automatically selects one of the resistive or memory IDs to communicate across at least one common pin of a plurality of pins and using the other of the resistive or memory sensor IDs to communicate across the at least one common pin based on a monitoring system type the sensor adapter cable is manufactured to connect with.
A sensor adapter cable comprising:
- a plug-in connector means for connecting to a plug-in module for a physiological monitor;
- a sensor connector means for connecting to an optical sensor;
- an interface cable that mechanically and electrically interconnects the plug-in connector means and the sensor connector means;
- and
- a pod means, including a circuit having both active and passive sensor identification elements, integrated with the interface cable for allowing a plurality of sensors to be connected to and be recognized by the plug-in module automatically wherein the circuit automatically switches between using one of the active or passive sensor identification elements to communicate across at least one common pin of a plurality of pins and using the other of the active or passive sensor identification elements to communicate across the at least one common pin based on a monitoring system type the sensor adapter cable is connected with.
