Patent ID: 10328224

Abstract:
A cleaning catheter includes an inflatable element expandable into contact with an inner surface of a ventilation tube. An input module includes a flow regulator, which is shaped so as to define a suction port coupleable in fluid communication with a suction source, and a fluid port coupled in fluid communication with a pressurized fluid source. A mechanical user control element is configured to mechanically and non-electrically set at least base and inflation/suction activation states of the flow regulator. When in the inflation/suction activation state, the flow regulator effects fluid communication between the suction port and a distal suction orifice, and effects inflation of the inflatable element by fluid communication between the fluid port and the inflatable element via a fluid-delivery lumen. The mechanical user control element includes one or more user-interface elements, a single one of which is arranged to set the flow regulator in the inflation/suction activation state.
