INTRAVENOUS LINE COUPLING DEVICE Abstract of the Disclosure A medical intravenous line coupling device can be secured to a standard "y" shaped junction tube, and to junction tubes having a terminal such as a septum. For the "y" tube arrangement, the device can comprise a single member which fits with the junction tube and has passages shaped to receive and secure with the "y" junction arm. A "b" shaped slot can be provided in the member for that purpose. The container can have a means 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 thereto. 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 recess, can hold the two members in the more secure position. For attachment to a tube with a terminal, the device can have a first member, such as a tube, with a portion that grips against the terminal to be held there- to. A second member mounted with the first member can bring about such gripping action, as by sliding movement. The first member can have flexible fingers with projecting lugs. Stops on the members can limit the degree of move- ment of the members in locked and unlocked positions. Interacting parts can hold the two members in the gripping position. Fingers with varying cross section can also be provided on the first member, with projections of the second member pressing against them for gripping ac- tion. A movement arm from the first member can extend through a slot in the second member to allow for limited movement, and the members can be shaped to releasably lock the members in position, as by providing a projecting nib.
