Abstract
An optical sensor, for positioning and holding an optical source and optical detector on opposite sides of a patient's finger or other extremity includes a clothespin-like housing having opposed housing members. The optical source and optical detector are embedded, respectively, in separate, opposed contact pads. The contact pads are mounted on the opposed housing members. A detent mechanism and a carrier associated with each of the housing members and contact pads allows the contact pads to be detached from the housing for cleaning or repair. A pivot mechanism that permits limited lateral as well as rotational movement of the housing members relative to each other allows the sensor to accommodate fingers of varying sizes.
