Abstract
A closed system adapter for catheters is disclosed. The adapter comprises a rigid outer housing having an inlet end with an internal cavity, and outlet end with a central passageway, the outlet end having a series of incrementally larger diameter steps permitting connection to various sized catheters. Positioned within the inlet end internal cavity is a resilient valve member normally biased to a sealed closed position. The valve member includes a generally cylindrical wall with a diaphragm with a pre-slit partitioned across the wall. The cylindrical wall dimensioned to be slightly larger in diameter than the inlet end cavity of the housing except for a recessed area where the diaphragm is positioned. The cylindrical wall providing inward compressive force except in the recess area permitting the diaphragm to remain in a steady state normally closed position without excessive inwardly compressive force.
