Patent ID: 6855138

Claim:
An injection joint for an intravenous (IV) device tube and comprising a connector with a first internal passage, an inlet, an outlet and a sealed injection port, wherein the inlet communicates with the first internal passage, the outlet communicates with the first internal passage and the sealed injection port comprises an injection port socket formed on the connector and comprising a proximal end; a distal end; a sidewall having an inner face with a bottom; a bottom plane having a center; a protrusion having a top and a second internal passage and formed integrally with and extending from the center of the bottom plane of the injection port socket, wherein the second internal passage communicates with the first internal passage in the connector; and an annular groove formed around the bottom of the inner face of the sidewall; a resilient plug attached to the injection port socket and comprising a cylindrical neck with a top end and a bottom; an eccentric cavity formed in the neck; a tapered flange integrally formed with and extending upward from the top end of the neck wherein the the tapered flange is larger than the neck; a bottom tube formed integrally with and extending downward from the bottom of the neck and mounted on the protrusion in the injection port socket, wherein the bottom tube is larger than the the neck and has an annular constriction formed around the bottom tube; and multiple through holes; and an annular shoulder formed where the neck joins the bottom tube; and a cap attached to the injection port socket, mounted around the resilient plug and comprising a distal end; a proximal end; a threaded nipple formed integrally with and extending upward from the distal end of the cap and having an axial passage, a top end and an opening formed in the top end, wherein the opening corresponds to the tapered flange of the resilient plug and the neck of the resilient plug is mounted in the axial passage in the threaded nipple and the tapered flange of the resilient plug is mounted in the opening in the threaded nipple when the resilient plug is mounted in the cap; a mounting ring formed integrally with and extending downward from the proximal end of the cap, wherein the mounting ring is mounted in the injection port socket; and a annular lip formed integrally with and extending radially out from the mounting ring, wherein the annular lip corresponds to and is securely held in the annular groove.
