VALVE MEANS FOR TRAINING MANIKIN

摘要

A valve means (1 ) is disclosed for use in a teaching manikin to simulate an open and closed airway of the human throat. The valve means comprises a section with a hollow passage and two end openings. A first opening fits onto a manikin head and a second opening seats on a sealing surface. When the head is tilted back the valve means (1) lifts to open the second end to permit the flow of air.
