Injection site located between parenteral fluid source and patient - providing an unobstructed flow of medication

摘要

The site comprises (a) a first inlet to which a conduit from a first liquid container is adapted to be connected; (b) a second inlet adapted to receive needle-injected medication; (c) an outlet through which the combined first liquid and injected medication can flow with the outlet adapted fro coupling to a conduit, and (d) a main body portion defining a single chamber that communicates with the first and second inlets and the outlet. The chamber has a sloped wall between the first inlet and the outlet, and has a cross-sectional area adjacent to the first and second inlets that is greater than the cross-sectional area of the chamber adjacent the outlet. The chamber has a cross-sectional area that is greater than the cross-sectional area of the first inlet; and has a length that is is not 1.5 inches to aid in preventing the medication that is injected from dropping through air. The second inlet and outlet are coaxial, whereby the needle is prevented from piercing the chamber, and the chamber is constructed to provide unobstructed flow of the first liquid and medication to the outlet.
