Abstract

1464954 Respiratory masks DRAGERWERK AG 29 April 1974 [28 April 1973] 18758/74 Heading A5T A breathing mask has a feeding tube 2, 4 extending through,an aperture in its wall 1, a valve 7 having a rounded closure surface being urged to close the inner end of the tube by two elongate elastic parts 8 interconnecting the valve 7 to spaced locations on the periphery of the tube, and the valve being intended to be opened to one side of the tube by a food-supplying outlet conduit inserted into the feeding tube at the other end. The elastic parts may be provided by a single elastic member 8 passing either through a bore 13 in the valve 7, which may be spherical, or along a groove (20 Figure 1 not shown) formed on the exterior of the valve (16). In use the load supplying outlet conduit seals against a ring 6 in the tube. A screwthreaded cap 5 closes the outer end of the tube.
