ABSTRACT:
A dual containment system is taught for adding sterile or caustic chemical, pharmaceutical, and biological fluids to and withdrawing them from a container. Included is a dual containment enabling fitting having a set of small diameter barbs at each end of a hollow conduit and a set of enlarged inner barbs at each end of a raised portion at the center of the hollow conduit. A port plate with a barbed spout is affixed to an aperture on the container. Also included is a dip tube with one end attached to a small diameter barb on the fitting and the other end extending into the container through the port plate spout. A connecting sheath encompasses the external portion of the dip tube and is attached at one end to a large diameter barb on the fitting and at the other end to the barbed spout. This creates a secondary containment chamber between the dip tube and the connecting sheath. The fitting may also be connected in series with a distal similarly functioning fitting creating a secondary containment chamber that allows the dual containment transfer of fluids. The secondary containment chamber prevents leakage and contamination and may be used for coaxial fluid flow, to effect a gas exchange with the fluid contents, and to cool or heat the fluid.
