Pulse oximeter access apparatus and method
First Claim
1. In a pulse oximetry system comprising a keyed sensor and a corresponding locked sensor port of a restricted access monitor, an access method comprising the steps of:
- obtaining a key including a memory element from a keyed sensor by removing said key from said keyed sensor, wherein said key of said keyed sensor comprises a memory element accessible by a memory reader associated with a locked sensor port of a restricted access monitor, said monitor configured to function when said sensor port is unlocked by said reader retrieving predetermined data from said memory element of said key;
integrating said key into an adapter cable; and
connecting said adapter cable between said sensor port and a unkeyed sensor so that said monitor functions with said unkeyed sensor.

Abstract
Access is provided to certain pulse oximetry systems utilizing a keyed sensor and a corresponding locked sensor port of a restricted access monitor. In such systems, the keyed sensor has a key comprising a memory element, and the monitor has a memory reader associated with the sensor port. The monitor is configured to function only when the key is in communications with the locked sensor port, and the memory reader is able to retrieve predetermined data from the memory element. The monitor is accessed by providing the key separate from the keyed sensor, integrating the key into an adapter cable, and connecting the adapter cable between the sensor port and an unkeyed sensor so that the monitor functions with the unkeyed sensor.
