  • Luer-actuated solution path connector with membrane and container using the connector and a method for establishing fluid communication with the container
    Patent number: 6874522
    Abstract: A connector, a container using the connector and a method for establishing fluid communication with a container. The connector may include a first coupling member and a second coupling member. The container may attach to the first coupling member. The first coupling member may have a first passageway with a spike and a membrane located therein. The second coupling member may have a second passageway. The first coupling member may engage the second coupling member and may further pierce the membrane with the spike. The first coupling member may further have a female end of a luer-lock, and the second coupling member may have a male end of a luer-lock. The first coupling member and the second coupling member may be engaged by twisting the male end and the female end of the coupling members to form the connector and establish fluid communication with the container.
