Abstract

A medical intravenous injection site is provided having a single piece elastomeric septum and valve combination element. The septum has a slit therein,through which a blunt cannula or a male luer slip or male luer taper can be inserted.
A valve element is suspended below the septum by straps extending between the septum and valve element, and formed integrally with them as a single, one-pieceelastomeric septum, valve, and strap structure. When the blunt cannula is inserted through the slit in the septum, the valve portion will be displaced away from the septum portion, and away from a valve seat formed in the interior of a substantially rigid housing in which the septum and valve structure is mounted. Fluid communication, in either direction past the valve seat, may therefore be established.
Because the septum is mounted across the end of the rigid housing, it is wipeable.
Thus, a needleless injection site is provided, thereby permitting injection of fluids to or withdrawal of fluids from a patient, through the injection site.
