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 lockout 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 board, incorporated within the interconnecting cable that electrically interfaces the sensor connector to the plug-in connector;
wherein the pod includes both active and passive identification elements;
wherein the circuit board comprises a first switch that, when closed, connects a resistor ID on the circuit board to the plug-in connector so as to enable a first plug-in attached to the plug-in connector to communicate with a sensor attached to the sensor connector, wherein the first switch is one of an n-channel or p-channel MOSFET;
wherein the circuit board comprises a second switch that, when closed, connects an EEPROM ID on the circuit board to the plug-in connector so as to enable a second plug-in attached to the plug-in connector to communicate with a sensor attached to the sensor connector, wherein the second switch is the other of an n-channel or p-channel MOSFET.
