ABSTRACT:
A simple and inexpensive assembly is provided for the purpose of dividing any hollow hypodermic needle into two separated flow conduits and connecting each such conduit with an associated pipe coupling means. The main part of said assembly consists of an elongated tongue member having a first portion dimensioned for insertion into the inner cavity of the needle in sealing contact with the cavity wall and a second portion wider than the first portion and designed to protrude from the rear end of the hypodermic needle when the first portion is inserted in said inner cavity. Further, the assembly comprises a pair of pipe stubs for hose connection and shaped for sealing bearing against opposite sides of the protruding second portion of the elongated tongue member and the rear end of the needle, in order to provide flow communication for each pipe stub with an individually associated one of the two separated flow conduits formed by insertion of the first portion of the tongue member into the inner cavity of the needle.
