1. A reusable component of a noninvasive optical sensor, the reusable component comprising:

  • a first housing that houses an emitter or a detector, wherein the first housing includes a locking feature, and wherein the detector is configured to detect energy emitted by the emitter after attenuation by body tissue, and wherein the locking feature of the first housing is configured to engage with a corresponding locking feature of a first receptacle of a disposable attachment component of the noninvasive optical sensor via sliding of the first housing within the first receptacle of the disposable attachment component;

    a second housing that houses another of the emitter or the detector, wherein the second housing includes an opening in a surface of the second housing that extends across at least a portion of the surface of the second housing, and wherein the opening is configured to receive a prong extending from a second receptacle of the disposable attachment component in response to mating the second housing with the second receptacle of the disposable attachment component;

    an electrical contact positioned within the opening in the surface of the second housing and that is accessible through the opening in the surface of the second housing, wherein the electrical contact is configured to contact the prong extending from the second receptacle of the disposable attachment component in response to mating the second housing with the second receptacle of the disposable attachment component; and

    a flexible connector that connects the first housing to the second housing, wherein the flexible connector is configured, in response to mating the reusable component with the disposable component and applying the noninvasive optical sensor to a tissue site of a patient, to provide tension to cause the locking feature of the first housing to engage with the corresponding locking feature of the first receptacle of the disposable attachment component by sliding of the first housing within the first receptacle of the disposable attachment component.
