13. A noninvasive optical oximetry sensor comprising:
-
a reusable portion comprising; a light source configured to transmit light of at least a first wavelength into tissue of a patient, a detector configured to detect the light after it interacts with the tissue of the patient and generate a signal responsive to the detected light, first mating elements, and first electrical contacts; and a disposable portion comprising; an electrical circuit element, second mating elements configured to mechanically mate with the first mating elements, wherein the first and second mating elements are configured to move with respect to one another to provide independent flexion of the reusable portion and the disposable portion during attachment of the sensor to the patient, the first and second mating elements permitting proper alignment in the sensor between the reusable portion and the disposable portion, and second electrical contacts in electrical communication with the electrical circuit element, the second electrical contacts electrically connecting to the first electrical contacts when the disposable portion is mated with the reusable portion, the sensor being inoperative when the first and second electrical contacts are not sufficiently proximate to one another to form a completed circuit that includes the electrical circuit element. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A reusable portion of a noninvasive optical oximetry sensor, the reusable portion comprising:
-
a light source configured to transmit light of at least a first wavelength into tissue of a patient, a detector configured to detect the light after it interacts with the tissue of the patient and generate a signal responsive to the detected light, first mating elements configured to mechanically mate with second mating elements of a disposable portion of the sensor, wherein the first and second mating elements are configured to move with respect to one another to provide independent flexion of the reusable portion and the disposable portion during attachment of the sensor to the patient, the first and second mating elements permitting proper alignment in the sensor between the reusable portion and the disposable portion; and first electrical contacts configured to electrically mate with second electrical contacts of the disposable portion to form a completed circuit that includes an electrical circuit element, the sensor being inoperative when the circuit is not completed. - View Dependent Claims (23, 24, 25, 26)

27. A disposable portion of a noninvasive optical oximetry sensor, the disposable portion comprising:
-
an electrical circuit element; first mating elements configured to mechanically mate with second mating elements of a reusable portion of the sensor, wherein the first and second mating elements are configured to move with respect to one another to provide independent flexion of the reusable portion and the disposable portion during attachment of the sensor to the patient, the first and second mating elements permitting proper alignment in the sensor between the reusable portion and the disposable portion, and first electrical contacts in electrical communication with the electrical circuit element, the first electrical contacts configured to electrically mate with second electrical contacts of the reusable portion to form a completed circuit that includes the electrical circuit element, the sensor being inoperative when the circuit is not completed. - View Dependent Claims (28, 29, 30, 31, 32)
