Abstract

1427962 Valves RICHARD WOLF GmbH 11 June 1973 [14 June 1972] 27737/73 Heading F2V [Also in Division A5] A flushing and suction device for fitting to endoscopes for use in ear, nose and throat examinations comprises a housing defining a chamber and accommodating a cylindrical rotatable plug 7 with passageways 10, 11 for connecting a pipe 4 for the endoscope to the chamber in two different positions of the plug and passageway 9 for respectively connecting pipes 5 and 6 to the chamber. In Fig. 2, the pipe 5 for suction is connected via passageway 10 to pipe 4. In Fig. 3, pipe 6 for pressure fluid is connected to the chamber which contains a flushing liquid which liquid is forced up a pipe 15 into passageway 11 and hence to pipe 4.
