Resposable pulse oximetry sensor
First Claim
1. A disposable component of an optical probe comprising:
- a disposable attachment mechanism including an adhesive side capable of removably securing a reusable component of an optical probe to a measurement site on body tissue, wherein the reusable component includes a light emitting source capable of emitting light at different wavelengths, a light detector capable of detecting the light after it has been attenuated by the body tissue, and a plurality of conductors; and
an information element; and
an electrical connection electrically connecting the information element to ones of the plurality of conductors in the reusable component when the reusable component and the disposable attachment mechanism are combined to form and optical probe, wherein the information element provides information about the optical probe.

Abstract
A pulse oximeter sensor has both a reusable and a disposable portion. The reusable portion of the sensor preserves the relatively long-lived and costly emitter, detector and connector components. The disposable portion of the sensor is the relatively inexpensive adhesive tape component that is used to secure the sensor to a measurement site, typically a patient'"'"'s finger or toe. The disposable portion of the sensor is removably attached to the reusable portion in a manner that allows the disposable portion to be readily replaced when the adhesive is expended or the tape becomes soiled or excessively worn. The disposable portion may also contain an information element useful for sensor identification or for security purposes to insure patient safety.
