1. 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 or the at least one detector, the first casing housing including at least one locking feature;
a second casing housing the other of the at least one energy emitter or the at least one detector, the second casing housing including;
at least one opening extending from a bottom edge of the second casing housing into at least a portion of a bottom surface of the second casing housing; and
at least one electrical component accessible through the at least one opening and capable of electrically communicating with a corresponding electrical component of a disposable attachment of the noninvasive optical sensor; and
a flexible portion connecting the first casing housing to the second casing housing, the flexible portion configured to provide tension to engage the at least one locking feature of the first casing housing with a corresponding locking feature of the disposable attachment in response to mating the reusable component with the disposable attachment component and applying the noninvasive optical sensor around a tissue site of a patient.
