Patent ID: 8670814

Claim:
A disposable optical probe comprising: a flex circuit housing a plurality of conductors, at least one emitter and a detector, wherein at least some of the conductors electrically communicate with the at least one emitter and others of the conductors electrically communicate with the detector, wherein the detector is capable of detecting light attenuated by body tissue at a measurement site, and wherein the flex circuit assembly also includes, first and second branches a cable connector portion, and an elongated neck portion electrically and mechanically connecting the first and second branches to the cable connector portion where each of the first and second branches diverges from one end of the elongated neck portion in a generally V-shaped configuration and the cable connector portion terminates the other end, the elongated neck portion being substantially longer than either of the first and second branches, the first branch positioning the at least one emitter and the second branch positioning the detector, the branches cooperating to provide variability in a distance from the at least one emitter to the detector; and a disposable flexible wrap extending from an end of one of said branches and configured for positioning said assembly with respect to the body tissue and further configured for stabilizing said variability in said distance and materially reducing the effect of light noise on the detector, wherein the disposable flexible wrap is capable of removably attaching said optical probe to the measurement site.
