Abstract

An endoscope (e.g., a duodenoscope) includes a bifluidic valve for controlling the flow of a liquid (e.g., water) and a gas (e.g., air) through a flexible tubular probe to respectively irrigate or insufflate an internal cavity of a patient. The bifluidic valve can be a single component, an interconnected assembly of components, or a plurality of separate components. Some examples of the bifluidic valve include a stepped diameter valve spool with radial or circumferential fluid passageways. In some examples, the bifluidic valve includes a tube pincher that can stop the water or other liquid from flowing through a flexible tube by pinching the tube shut. Some example bifluidic valves include a valve housing that is resiliently flexible to urge the valve to a normally closed position. In some examples, selectively covering or uncovering a vent in the valve housing controls the flow of air for insufflation.
