A needleless IV injection port assembly includes a spiked body provided with a hollow spike, a female luer component, a flexible and resilient spike boot having a tip and spring portion, a centering member, and a-resilient swabbable septum. The spike boot extends over the spike, the centering member is provided over a portion of the spike and spike boot, and the septum is provided between the centering member and an end of the female luer component. The spiked body and the female luer component are secured together to complete the assembly. The length of the female luer component and/or the length of the spike is chosen so that when a separate male luer is positioned over a protuberance on the septum and pushed into the female luer component, the male luer places pressure upon the septum which thereby urges the septum toward the spike. The pressure on the septum causes the spring portion of the boot to be compressed and the tip portion of the boot to be pierced by the tip of the spike. As the septum is further compressed, the septum extends over the spike, with a pre-slit hole in the septum facilitating the extension thereover, such that a hollow of the spike is in fluid communication with the male luer connector. The injection port causes minimal reflux, and the spike boot and septum provide a swabbable antibacterial double barrier over the spike.

[ What is claimed is:] [1.] An injection port assembly for coupling to and uncoupling from a first fluid pathway of a first connector and for receiving and passing a fluid into the first fluid pathway from a device provided with a second connector, said injection port assembly comprising:a) a body having a first end provided with a first mating structure adapted to mate with the first connector, and a second end;b) a hollow spike defining a shaft having a first end coupled to said body and a second end provided with a penetrating tip, said first mating structure and said hollow spike being in fluid communication with each other;c) a resilient first barrier extending over said spike and having a tip portion about said tip of said spike;d) a resilient second barrier provided over and contacting said tip portion of said first barrier; ande) a hollow component having a first end and a second end, said first end being coupled to said body, said hollow component extending around at least portions of said spike, said first barrier and said second barrier, and said second end being provided with a second mating structure adapted to removably couple to the second connector,wherein when the second connector is coupled to said second mating structure, said second connector forces said second resilient barrier and said tip portion of said first resilient barrier over said spike such that said second connector and said first connector are in fluid communication with each other through said hollow spike and said first mating structure.
