Abstract
A protected needle coupling for connecting to a conventional IV injection site comprises an elongated tubular housing having a proximal end and a distal end, a needle mounted at the proximal end and extending coaxially toward the distal end to a protected position within the housing, a connector at the proximal end for connecting to an IV tubing, and a telescoping tubular member reciprocally mounted in said housing and having axially extending slits defining a pair of opposed semi-cylindrical fingers extendable from the distal end of the housing, and having inwardly directed shoulders at the outer ends thereof for engaging a shoulder of an IV injection port for pulling the injection port into the housing for coupling engagement with the needle therein, and a tab extending outward from the telescoping member for manually forcing the telescoping member into the housing.
