Abstract
An improved needle-free intravenous injection port assembly is disclosed. Embodiments include a boot valve with a helical surface, a boot valve and septum which mate with mechanical interference, a spike with a rough outer surface coated with a lubricant, a septum having a shoulder and a single continuous swabbable surface, a septum and a boot valve which are pre-punctured, a septum with a frustroconical extension and a combination single piece septum and boot valve. The injection port assembly provides zero fluid displacement during coupling and uncoupling.
Claims6
An injection port assembly for coupling to and uncoupling from a first fluid pathway of a first connector and for coupling to a device provided with a second connector so as to provide a fluid connection between the first and second connectors, said injection port assembly comprising:
- a body having a first mating structure adapted to mate with the first connector and a second mating structure coupled to said first mating structure and adapted to mate with the second connector,
- a resilient barrier substantially contained within said body and compressible from a first position in which fluid flow between said first mating structure and said second mating structure is blocked to a more compressed second position in which fluid flow between said first mating structure and said second mating structure is permitted,
- said resilient barrier having a generally helical outer surface pattern and a regular polygonal inner surface along at least a portion of its length.
