<P>PROBLEM TO BE SOLVED: To provide a needleless access port valves having a piston comprising slit along a piston section for creating a fluid flow path. <P>SOLUTION: The needleless access port valves are generally described herein with particular discussions extended to needleless access port valves incorporating a piston comprising slit along an upper piston section for corresponding to fluid flow. The slit is closed by the relative geometry of the piston and the valve housing, which acts to terminate fluid flow between the inlet and outlet of the valve assembly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
