Patent ID: 8781549

Claim:
A noninvasive optical oximetry sensor, the sensor when assembled configured to attach to a measurement site of a monitored patient and to output signals responsive to light absorption by tissue at said measurement site, said signals including sufficient information for an oximeter to determine one or more physiological parameters of the patient including at least one of oxygen saturation or pulse rate, the oximetry sensor comprising: a disposable portion including slots; and a reusable portion including: a flex circuit; a light source; one or more detectors configured to detect light from said light source after attenuation by said tissue and output said signals responsive to said detected light; a plurality of conductors proximate said flex circuit, some of said conductors communicating with said light source and others of said conductors communicating with said one or more detectors; a protective coating encasing at least said light source, said one or more detectors and at least some of said conductors and some of said flex circuit; and tabs proximate at least said light source and said one or more detectors, wherein said tabs are configured to mate with said slots of said disposable portion where at least some of said slots are shaped to allow said tabs to move within said mated slots to self-adjust the disposable portion and the reusable portion with respect to one another when the disposable portion is applied to said patient after sensor assembly.
