Optical sensor
First Claim
1. A non-invasive optical sensor comprising:
- a hinged clothespin-like housing having a pair of opposed faces;
a first contact pad having an optical source associated therewith;
a second contact pad having an optical detector associated therewith; and
releasable means for securing said first and second optical pads to said opposed faces of said housing;
said first and second contact pads and said optical source and said optical sensor associated therewith thereby being readily separable from said housing for cleaning or replacement;
said releasable means including a first detachable carrier engageable with one of said opposed faces and a second detachable carrier engageable with the other of said opposed faces;
said first and second detachable carriers engaging respective detents in said housing adjacent said opposed faces;
said housing further including depressable means for selectively disengaging said first and second carrier from said respective detents.

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.
