Abstract
A check valve for a fluid administration system. A connector includes a housing, and first and second conduits defined by the housing, wherein the first conduit is in fluid communication with the second conduit. A check valve is disposed within the housing and includes a first body portion defining a first passageway for fluid flow, and a second body portion defining a second passageway for fluid flow. The first and second passageways are in fluid communication with one another and the second body portion is movable relative to the first body portion between first and a second positions. When the second body portion is in the first position, fluid flow may occur in a first direction, but not in a second direction substantially opposite to the first direction. When the second body portion is in the second position, fluid flow may occur in the second direction.
