Abstract
A syringe, particularly a vaginal douche, has a cannula consisting of an elongated hollow tubular body having one open end and an opposed transverse end wall formed with an opening through which a central axis of the cannula body extends. The cannula body has substantially midway between its ends a transverse minimum cross section while tapering only slightly from the transverse end wall toward the minimum cross section. Between its open end and its minimum cross section the cannula body tapers to a substantially greater degree and has the configuration of part of a hollow cone. At its exterior between its minimum cross section and transverse end wall the cannula body is formed with grooves uniformly distributed about the central axis of the cannula body and separated from each other by ribs. Adjacent but inwardly of these ribs the cannula body is formed with additional openings passing therethrough so that a liquid can discharge through the cannula openings. At its open end the cannula is internally threaded for attachment to a squeeze bottle.
