Patent ID: 8600467

Claim:
A reusable component of a noninvasive optical sensor, the reusable component comprising: at least one energy emitter; at least one detector capable of detecting energy attenuated by body tissue and capable of outputting a signal usable to determine one or more physiological characteristics of the body tissue; a first casing housing one of the at least one energy emitter and the at least one detector, the first casing comprising at least one locking feature configured to interact with a corresponding locking feature of a disposable attachment of the noninvasive optical sensor upon application of the disposable attachment to the patient to fix movement of the first casing and the disposable attachment with respect to one another in at least one direction; a second casing housing the other of the at least one energy emitter and the at least one detector, comprising: a front portion having a bottom surface and a front surface extending from the bottom surface; at least one electrical component capable of electrically communicating with at least one corresponding electrical component in the disposable attachment; and at least one opening in the second casing extending along at least a portion of the bottom surface and at least a portion of front surface, the at least one electrical component of the reusable component accessible through the at least one opening.
