Abstract
A medical intravenous line coupling device can be secured to standard "y" shaped junction tube. The device can comprise a single member which fits with the junction tube and has passages shaped to receive and secure with the junction arm. A "b" shaped slot can be provided in the member for that purpose. The container can have a menas for receiving a liquid for injection into the intravenous system, such as a receptacle, and a means for allowing liquid flow from the receiver into the junction tube, such as a needle. The device may include a second member which has a passage to interact with the junction arm. One member can fit about the other and be rotatably mounted hereto. The junction arm can be received by the two members when they are in a first position relative to one another, and can be secured when the members are moved relative to each other. With the two member assembly, the receiver, such as the receptacle, and the liquid flow means, such as the needle, can be mounted to the first or second member. Structure, such as a nib projecting into a slot, can be provided to resist movement of the arm out of a secure relationship. Means, such as an interacting projection and a rec…
