Abstract

650,053. Liquid - injecting apparatus. AGUIAR, C. de P. Dec. 30, 1947, Nos. 34711 and 34712. Convention dates, Nov. 24, 1941, and July 30, 1942. [Class 81(ii)] A nozzle for a flexible tube for insertion in body cavities is characterized by the provision of small passages or channels 15 extending rearwardly through the wall of the nozzle so that fluid forced into the tube will emerge from the nozzle in a number of rearwardly-directed thin streams thus impelling the nozzle forwardly. In the construction shown in Fig. 4, a salient portion 16 is provided to minimise turbulence of the stream of fluid.
