Abstract: A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.

Abstract: An actuation ball valve has an elongated knob which replaces prior art quarter turn valves. The knob comprises a thread that runs along a cylindrical portion of the knob, wherein the nut has a corresponding cut-out for the thread. This helps the knob move/slide in and out of the nut. The knob and nut are designed so that a specific distance can be covered in a quarter turn, as the valve moves from its horizontal (OFF) position to its vertical (ON) position. The knob and nut can be modified to travel various distances at different degrees of turn to actuate the system being controlled. The knob has a cut-out at the bottom which is used to insert one or more washers and a self-threading screw to stop the rotation of the knob with respect to the nut at it moves out in the OFF position.
