A fluid control device for directing fluid flow comprising a needleless access device for transferring fluids and methods of directing fluid flow. The fluid control device may have a first port, a second port, a third port and a connecting portion joining the first, second and third ports. A first valve element may be positioned within the first port and a fluid director may be positioned within the connecting portion. The first valve element may move between an opening position, where fluid may flow past the first valve element, and a closed position, where fluid may be prevented from flowing past the first valve element. The fluid director may have at least one passageway for connecting at least two of the first, second and third ports such that fluid may flow therebetween. An actuation mechanism may be used to orient the fluid director and, consequently, the at least one passageway within the connecting portion.

1. A fluid control device comprising: a monolithic housing having a first port, a second port, a third port, and a connecting portion connecting the first, second, and third ports, wherein the connecting portion comprises an opening; anda fluid director comprising a fourth port, the fluid director rotatably disposed within the opening of the connecting portion and having a plurality of rotational positions configured to place only two of the first, second, and third ports in fluid communication in each of the plurality of rotational positions;wherein the fourth port is in fluid communication with the two of the first, second, and third ports in fluid communication in each of the plurality of rotational positions. 2. The device of claim 1, wherein: at least one of the first, second, third, and fourth ports comprise a channel having an opening portion, and a valve element positioned at least partially within the channel, and the valve element comprises a proximal end; and wherein the at least one of the first, second, third, and fourth ports are configured such that the proximal end of the valve element is flush with the opening portion when the respective port is not engaged by a fluid transfer device. 3. The device of claim 1, wherein: the first port and the second port are aligned along a common axis; andthe third port comprises a first centerline axis; andthe first centerline axis of the third port is perpendicular to the common axis of the first and second ports. 4. The device of claim 3, wherein: the opening of the connecting portion comprises a second centerline axis; andthe second centerline axis of the opening of the connecting portion is perpendicular to both the common axis of the first and second ports and the first centerline axis of the third port. 5. The device of claim 2, wherein the proximal end of the valve element comprises a continuous enlarged surface. 6. The device of claim 2, wherein the valve element comprises an elastomeric material. 7. The device of claim4, wherein: the fluid director comprises a recess;the opening of the connecting portion comprises a protrusion; andthe fluid director and connecting portion are configured such that the protrusion engages the recess when the fluid director is disposed within the connecting portion so as to reduce movement of the fluid director along the second centerline axis with respect to the connecting portion. 8. The device of claim 1, wherein the fluid director is in fluid communication with the first port, the second port, and the third port in each of a first, second, and third rotational position of the fluid director. 9. A fluid control device comprising: a monolithic housing having a first port, a second port, a third port, and a connecting portion connecting the first, second, and third ports, wherein the connecting portion comprises an opening; anda fluid director comprising a fourth port, the fluid director rotatably disposed within the opening of the connecting portion and having a plurality of rotational positions configured to place two or more of the first, second, and third ports in fluid communication in each of the plurality of rotational positions;wherein the fourth port is in fluid communication with the two or more of the first, second, and third ports in fluid communication in each of the plurality of rotational positions of the fluid director. 10. The device of claim 9, wherein: the first port and the second port are aligned along a common axis; andthe third port comprises a first centerline axis; andthe first centerline axis of the third port is perpendicular to the common axis of the first and second ports. 11. The device of claim 10, wherein: the opening of the connecting portion comprises a second centerline axis; andthe second centerline axis of the opening of the connecting portion is perpendicular to both the common axis of the first and second ports and the first centerline axis of the third port. 12. The device of claim 9, wherein: the first port comprises a male luer connector; andthe second port comprises a female luer connector. 13. The device of claim 9, wherein the first port comprises a male luer connector. 14. The device of claim 11, wherein: the fluid director comprises a recess;the opening of the connecting portion comprises a protrusion; andthe fluid director and connecting portion are configured such that the protrusion engages the recess when the fluid director is disposed within the connecting portion so as to reduce movement of the fluid director along the second centerline axis with respect to the connecting portion. 15. A fluid control device comprising: a monolithic housing having a first port, a second port, a third port, and a connecting portion connecting the first, second and third ports, and a fluid director comprising a fourth port,wherein (i) at least one of the first port, second port, or third port comprises a channel having an opening portion and a valve element, positioned at least partially within the channel, and flush with the opening portion when the respective port is not engaged by a fluid transfer device, and (ii) the fluid director, rotatably disposed within an opening of the connecting portion, having a plurality of rotational positions within the opening configured to place the first port in fluid communication only with the second port when in a first rotational position, to place the first port in fluid communication only with the third port when in a second rotational position, and to place the second port only in fluid communication with the third port when in a rotational third position; andwherein the fourth port is in fluid communication with the first and second ports, the first and third ports, and the second and third ports in each of the first, second, and third rotational positions of the fluid director, respectively. 16. The device of claim 15, wherein the proximal end of the valve element comprises a continuous enlarged surface. 17. The device of claim 15, wherein the valve element comprises an elastomeric material. 18. The device of claim 15, wherein: the fluid director comprises a recess;the opening of the connecting portion comprises a protrusion; andthe fluid director and connecting portion are configured such that the protrusion engages the recess when the fluid director is disposed within the connecting portion so as to reduce movement of the fluid director along a centerline axis with respect to the connecting portion.
