The tubular unit with vessel engaging cuff structure is a unitary unit including a tube having a compressible cuff surrounding the outer surface thereof. The cuff includes a resilient, porous inner material surrounding the tube and an outer liquid impervious layer which may be bonded to or integrally formed with the inner material. The tube may include means to evacuate fluid from the cuff or, alternatively, separate means are directly connected to the cuff to accomplish such evacuation and contraction of the cuff. Vessel engaging appendages may be incorporated on the cuff.

Apparatus for selective controlled volume and rate administration of parenteral solutions, blood and the like, wherein sight and flow control problems caused by splashing and foaming of fluids having high surface tension such as blood are substantially diminished, and flow rates during different time phases of operation are optimized due to an arrangement of structure providing an increased head pressure on flow of fluid to a measuring chamber.

The plasmapheresis assembly includes a novel Y connector valving structure to replace conventional tube clamps. This valving structure eliminates dead spaces for blood to collect and clot and provides a fluid tight seal during heat sterilization without causing deformation of the tubing for the assembly. Possible erroneous connection of assembly components with resultant contamination is eliminated by the use of unique mating connectors in place of spikes or needle connectors. These mating connectors are employed in a simple and efficient blood bag construction to provide substantially rigid access ports to facilitate rapid manual manipulation of the blood bags.
