A port assembly includes a housing with an opening and a bore therethrough, a slit septum disposed in the opening to control access through the opening, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum and a second end aligned with the membrane, and a resilient member disposed between the perforator and the base. The perforator has first and second lumens, the first lumen extending between the first and second ends of the perforator and the second lumen extending between a point between the first and second ends and the second end. The perforator also has a seal disposed about the first lumen at the first end of the perforator, and a valve associated with the second lumen to limit flow of fluid through the second lumen in the direction of the second end.

Port assembly for use with needleless connector

A port assembly includes a valve housing with an inlet opening, a valve disposed in the valve housing to control access through the inlet opening, and a base joined to the valve housing and having a bore therethrough. The bore has a closed end defined by a frangible barrier, and a pushrod is disposed in the bore between the valve and the frangible barrier, axial movement of the pushrod causing rupture of the frangible barrier. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit is defined, at least in part, by a port assembly.

A flow control valve includes a stem extending into an interior bore defined by a wall of a flow control member of the valve, the stem and the wall defining therebetween a cylindrical space allowing fluid communication between apertures formed in differing planes of the flow control member.

Multirate tubing flow control valve

A flow control valve for medical liquid is disclosed. The valve has a housing including an inlet, an outlet, and a flow path therebetween. A plurality of flow restrictors are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member is rotationally movable and defines an annular gap and radial groove which provide fluid communication between the different planes and the outlet regardless of the orientation of the flow control member. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.
