FIG. 1 is a bottom plan view of an aspirator tube, showing my new design;
FIG. 2 is a side elevational view thereof;
FIG. 3 is an end view as seen from the upper end of FIG. 1;
FIG. 4 is a cross section taken on line IV--IV of FIG. 2; and
FIG. 5 is an end perspective view as seen from the lower end of FIG. 1 with portions fragmentarily shown for ease of illustration.
The characteristic features of my design reside in the specific configuration of the distal end portion of the tube and the flared coupling at the proximal end, as best illustrated in FIGS. 1 and 2 of the drawing.
