Patent number: 10675393Abstract: A device that helps clear a fluid or other material lodged in a person's throat has a barrel with an open proximal end and an opening laden distal end. A plunger is slidably disposed within the barrel such that the plunger, by being manually drawn outwardly, creates suction within the barrel drawing air through the opening. A single or multi-section tube, flexible on at least its distal end, is fluid flow connected to the opening and has a face mask along its length. The distal end of the tube is intubated with a person proximate the fluid or other material so that as the plunger is drawn outwardly through the barrel, the suction created within the barrel causes air to be drawing in through the tube and into the barrel thereby helping draw out and dislodge the fluid or other material. A backflow valve located on the barrel helps clear the barrel of such things as vomit that might have been drawn into the barrel.Type: GrantFiled: July 15, 2016Date of Patent: June 9, 2020Assignee: Dechoker LLCInventor: Alan R Carver
