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.
Claims12
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.
