Abstract: A novel one-piece fluid reservoir assembly for use in conjunction with an insulin infusion pump. The single piece fluid reservoir assembly includes a barrel body, a male luer fitting integral with the barrel body, a sealing surface integral with the barrel body, the sealing surface for sealing against the pump housing when the fluid reservoir assembly is inserted into the pump housing. Further, the barrel includes, as part of the one-piece fluid reservoir assembly, threads for engagement with threads on an opening in the fluid pump so that the fluid assembly can be inserted into the fluid pump, engage the threads and rotation therewith will locate the fluid reservoir assembly within the pump. Thereafter, a piston in the pump may be incrementally advanced to act upon a plunger in the barrel assembly to force a fluid within the barrel assembly through the male luer fitting and through a conduit engaged therewith to a remote infusion set.

Abstract: This invention relates to therapeutic infusion assemblies, more specifically a device for the subcutaneous delivery of a fluid from a remote source. Applicant provides a base assembly which has a fluid channel therein and a cannula extending vertically downward from a flat bottom. A fluid connector member which receives a fluid bearing line from the remote fluid source and the fluid connector member pivotably and removably connects to the base member. The manner of connection is “hinged” allowing the fluid connector to move from a non-use position by rotation downward to a used position. In the use position a fluid channel in the fluid connector will connect with a fluid channel in the base to provide fluid to the cannula and to the patient.
