Sensor adapter cable
First Claim
1. 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.
