Abstract: 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.

Abstract: Medical intravenous administration connectors include a first coupling member having a female luer, a valve member having a substantially rigid stem and a substantially resilient body with a sealing surface, and a second coupling member having a fluid coupling extending from one end and an internal valve member support. The coupling members are structured to couple to each other with the valve member being biased to a closed position. When assembled, the valve stem extends into the female luer, and the valve body biases the sealing surface against an annular ring in the first coupling member thereby blocking fluid communication. Preferably, vanes are provided in the second coupling member on which the resilient body of the valve sits, with the vanes acting as a centering mechanism for the valve. The valve may be opened for fluid flow through the assembly by coupling a male luer to the female luer of the assembly, or by pressure actuation.
