Method of sterilizing a reusable portion of a noninvasive optical probe
First Claim
1. A method of sterilizing a reusable portion of a noninvasive optical probe to assemble a new noninvasive optical probe, the method comprising:
- removing said noninvasive optical probe from a patient, said probe comprising a reusable element and a separable disposable positioning mechanism, the disposable positioning mechanism including a first information memory storage element that remains attached to the disposable positioning mechanism when the reusable element is separated from the disposable positioning mechanism, the disposable positioning mechanism further including an adhesive side capable of removably securing the reusable element to a measurement site on said patient, the reusable element including a light source capable of emitting light at different wavelengths, a light detector capable of detecting the light after it has been attenuated by the patient'"'"'s body tissue, and a plurality of conductors, wherein the light source and the light detector form part of the reusable element when the reusable element is separated from the disposable positioning mechanism;
separating said reusable element from said disposable positioning mechanism;
sterilizing at least said reusable element; and
combining said reusable element with a different disposable positioning mechanism to form a second optical probe, said combining including electrically connecting a second information memory storage element of said second optical probe, wherein said second information memory storage element forms a portion of said different disposable positioning mechanism.

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.
