Abstract

A connector is provided for attachment of a syringe to a dispenser adapted to provide measured quantities of pressured gas to the syringe to displace the contents of the syringe in measured drops. The connector includes a flexible conduit attached at one end to the dispenser and attached at its opposite end to the filling end of a syringe while gripping the oppositely disposed projections, or 'ears', of the syringe. There is an externally threaded tube at the syringe end of the flexible conduit, terminated by a stopper member which has a cylindrical end portion sized to fit loosely within the filling end of the syringe, which end portion is joined to a sealing flange. The sealing flange abuts the flat surface at the filling end of the syringe while the syringe 'ears' are retained within oppositely disposed channels after a knurled ring on the externally threaded tubular member is rotated.
