In this way, should “compression setting” of the elastic portion of the valve stem take place, the additional spring will ensure that the valve head is still able to be engaged with the valve seat to thereby close the valve.Type: GrantFiled: March 15, 2004Date of Patent: February 14, 2006Assignee: ITW New Zealand LimitedInventor: Andrew Nicholson Wrigley

Patent number: 6991215Abstract: A one-way valve assembly can be fitted to the end of a syringe to allow fluid to flow from the syringe and into a body cavity but to prevent backflow. The valve assembly is opened by insertion of the luer tip of the syringe into the assembly inlet. The valve has an internal elastic member that forms a variable volume internal chamber. This chamber expands upon insertion of the luer tip into the inlet and shrinks when the luer tip is removed from the assembly. The shrinking action creates a positive pressure in the valve assembly to prevent backflow.Type: GrantFiled: July 1, 2002Date of Patent: January 31, 2006Assignee: Occupational & Medical Innovations, Ltd.Inventor: Bruce Leigh Kiehne

Patent number: 6971630Abstract: A needle free medical connector includes a housing with a first port and a second port. The connector also includes a piston element defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has a compressible section having a variable inner width that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the compressible section self-expands in width thereby maintaining or increasing the volume of the fluid passageway through the connector. The compressible section has a configuration permitting the continuous flow of fluid through its entirety.Type: GrantFiled: August 6, 2004Date of Patent: December 6, 2005Assignee: Alaris Medical Systems, Inc.Inventors: Karl R.
