Pulse oximetry sensor adapter
First Claim
1. An adapter configured to provide an interconnection between a pulse oximetry sensor and a monitor, said sensor having a light source and a light detector, said monitor having a driver and a signal conditioner, said adapter comprising:
- a plurality of signal paths configured for detachable connection to at least one of said monitor and said sensor, a first of said signal paths in communication with said driver and said light source when said adapter is in communication with said monitor and said sensor, and a second of said signal paths in communication with said light detector and said signal conditioner when said adapter is in communication with to said sensor; and
an adapter element connected to at least one of said firs and said second signal paths, said adapter element modifying a characteristic of said at least one signal path so that said sensor and said monitor are jointly operable to measure oxygen status.

Abstract
An adapter allows the interconnection of a sensor originating from one manufacturer to be coupled with conventionally incompatible monitors originating from other manufacturers to form a properly functioning pulse oximetry system. The adapter matches a sensor driver in a monitor to the current requirements and light source configuration of a sensor. The adapter also matches a sensor'"'"'s light detector signal level to the dynamic range requirements of a monitor preamplifier. Further, the adapter provides compatible sensor calibration, sensor type and security information to a monitor. The adapter may have a self-contained power source or it may derive power from the monitor, allowing both passive and active adapter components. The adapter is particular suited as an adapter cable, replacing a conventional patient cable or sensor cable as the interconnection between a sensor to a monitor in a pulse oximetry system.
