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.

Optical sensor

A system for handling and disposing of respiratory waste from a patient's respiratory circuit. The system includes a device for providing an inhalable input fluid containing a gas to the patient's respiratory circuit, a device for providing an output path for the expired respiratory waste, a device for filtering and handling the respiratory waste with a filter portion including (a) an input port on a first side of a filter media for separating a gas from liquids and solids, (b) a first chamber on the first side, (c) a first output port for liquids and solids on the first side, (d) a second side of the filter media having a second chamber and (e) a second output port on the second side of the filter media for the gas with the first chamber geometry enabling preferential removal of any solids occluding the filter media preventing gas flow to the second chamber.
