Abstract

A valve assembly having a body, an end cap, a resilient septum, and an actuator. The body forms a plurality of fluid recesses. The end cap defines a plurality of projections that form channels. The septum is positioned between the body and the end cap. An actuator device is positioned adjacent the septum for moving the septum away from a shoulder defined in the body to allow fluid to pass through the body, actuator, and end cap. The assembly can include a sharp. The sharp extends through the body, the actuator, the septum and the end cap.

Claims

1. A valve assembly comprising:

a body having a first end and a second end, said body defining a passageway extending between said first and second ends, said body defining a sealing surface in said passageway;

a resilient septum positioned in said passageway in sealing engagement with said sealing surface, said septum having a substantially solid cylindrical shape;

means for disengaging said septum from said sealing surface to allow fluid flow through said passageway.

2. The valve assembly of claim 1, wherein said septum is self-sealing upon insertion and withdrawal of a needle therethrough.

3. The valve assembly of claim 1, wherein said septum is substantially solid in form.

4. A valve assembly comprising:

a body having a first end, a second end, an exterior surface, and an interior surface, said interior surface defining a substantially cylindrical side wall extending between said first and second ends and a substantially annular septum shoulder adjacent said second end, said cylindrical side wall having a plurality of fluid recesses;

an end cap adjacent said first end of said body, said end cap having an attachment end, a body end, an outer surface and an inner surface, said body end including a plurality of outwardly extending projections;

a resilient septum having a substantially solid cylindrical shape, a shoulder surface, an opposed projections surface, and a substantially circular chamber wall extending between said shoulder and projection surfaces, said shoulder surface engaging said septum shoulder to form a seal, said projections surface engaging said projections to form an end cap fluid passageway, said chamber wall together with said cylindrical side wall forming a plurality of chamber fluid passageways, said chamber fluid passageways being in communication with said end cap passageway;

actuator means positioned in said body fluid passageway adjacent said second end of said body for moving said shoulder surface of said septum away from said shoulder to allow fluid to flow through said chamber and end cap fluid passageways.

5. The valve assembly of claim 4, wherein said exterior surface of said body defines attachment means adjacent said second end.

6. The valve assembly of claim 4, wherein said interior surface of said body defines a substantially annular actuator shoulder in said body fluid passageway, said actuator shoulder being shaped to retain said actuator means within said body.

7. The valve assembly of claim 6, wherein said actuator means is comprised of an actuator body having a first actuator end, a second actuator end, an exterior actuator surface and an interior actuator surface, said interior actuator surface defining an actuator fluid passageway extending between said first actuator end and said second actuator end, said actuator exterior surface defining an annular septum contact surface and an opposed actuator shoulder contact surface, said septum contact surface engaging said septum, and said actuator shoulder contact surface engaging said actuator shoulder.
