Publication number: 20190381266Abstract: A closed suction cleaning system includes an interface coupled to a main body inlet of a multi-port tube-connector assembly for coupling to an endotracheal tube. A catheter main body includes a distal inflatable element positioned along a distal end portion of the catheter main body. An input module is located at a proximal end of the catheter main body. The input module includes a flow regulator with a mechanical user control element. In a first configuring step, the flow regulator simultaneously regulates suction through the catheter main body and inflation of the distal inflatable element. After a second configuring step, the flow regulator and mechanical user control element may regulate suction through a suction lumen but not cause inflation of the distal inflatable element. A pliable sleeve inhibits contamination of a portion of the catheter main body from an external environment.Type: ApplicationFiled: June 24, 2019Publication date: December 19, 2019Inventors: Oron ZACHAR, Elad EINAV, Gil YIGAL

Patent number: 10328224Abstract: 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.Type: GrantFiled: March 14, 2016Date of Patent: June 25, 2019Assignee: TELEFLEX LIFE SCIENCES UNLIMITED COMPANYInventors: Oron Zachar, Elad Einav, Gil Yigal
