Abstract
The attachment unit for a spike equipped syringe is composed of first and second tubular portions connected together at their inner ends and extending from such connection in axially aligned relation. The bore of the first tubular portion has at its outer end a cylindrically shaped seat for the hub of the spike, and adjacent to such cylindrical seat a conical seat for the spike, the two seats forming between them an internal shoulder to properly register the spike in such first tubular portion. Connected at its inner end to said connection and enclosed in the inner end of the second tubular portion is a tubular needle mounting, the bore of which is in communication with the bore of the first tubular portion. One end of a needle cannula is secured in liquid-tight relation in the mounting bore and the cannula extends from such mounting and through the bore of the second tubular portion to a point beyond the outer end of such second tubular portion. The projecting end of the cannula is enclosed by a cup-shaped cap which fits on the outer end of the second tubular portion and is provided with a stop flange engageable with such outer end of the second tubular portion to prevent the needle engaging the closed end of the cap.
