<p>LAVAGE SYSTEM HAVING A NOZZLE Medical spray device, in particular a lavage system, comprises a compressed gas supply conduit (4, 54) for generating a gas flow, a liquid supply conduit (32, 82) for supplying a liquid, a dispensing tube (24, 74) having an open tube end for spraying fine droplets or a spray mist of a liquid-gas mixture, and an operable valve element (6, 56) that is arranged in the compressed gas supply conduit (4, 54). A constriction (26, 76) of the cross-sectional area is provided in the dispensing tube (24, 74) and a merging site (30, 80) is arranged in the region of the constriction (26, 76) through which the liquid merges into the gas flow from the compressed gas supply conduit (4, 54), whereby the constriction (26, 76) forms a nozzle in the dispensing tube (24, 74). 28 36 26 24 2 4 10 8 6 16 0 36 26 30 38 32 12 Figure 2</p> |
