Abstract

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.

Claims

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 third port comprises a needleless access port and the connecting portion comprises an opening; and

a fluid director rotatably disposed within the opening of the connecting portion of the housing, wherein the fluid director has a plurality of rotational positions within the opening of the connecting portion and is 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;

wherein the fluid director comprises a needleless access port that is in fluid communication with the first port, the second port, and the third port in each of the first, second, and third rotational positions of the fluid director.

2. The device of claim 1, wherein:

the first port and the second port are aligned along a common axis; and

the third port comprises a first centerline axis; and

the first centerline axis of the third port is perpendicular to the common axis of the first and second ports.

3. The device of claim 2, wherein:

the opening of the connecting portion comprises a second centerline axis; and

the 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.

4. The device of claim 1, wherein:

the first port comprises a male luer connector; and

the second port comprises a female luer connector.

5. The device of claim 1, wherein:

the first port comprises a male luer connector; and

the second port comprises a needleless access port.

6. The device of claim 1, wherein:

the needleless access port comprises an opening and a valve element;

the valve element is disposed within the access port and comprises a proximal end; and

the needleless access port is configured such that the proximal end of the valve element is flush with the opening when the needleless access port is not engaged by a fluid transfer device.

7. The device of claim 6, wherein the proximal end of the valve element comprises a continuous enlarged surface.

8. The device of claim 6, wherein the valve element comprises an elastomeric material.

9. The device of claim 2, wherein:

the fluid director comprises a recess;

the opening of the connecting portion comprises a protrusion; and

the 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.

10. 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 (i) the third port comprises a needleless access port comprising an opening and a valve element and (ii) the connecting portion comprises an opening, wherein the valve element is disposed within the needleless access port and comprises a proximal end, and wherein the needleless access port is configured such that the proximal end of the valve element is flush with the opening when the needleless access port is not engaged by a fluid transfer device; and

a fluid director rotatably disposed within the opening of the connecting portion of the housing, wherein the fluid director has a plurality of rotational positions within the opening of the connecting portion and is 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.

11. The device of claim 10, wherein:

the first port and the second port are aligned along a common axis; and

the third port comprises a first centerline axis; and

the first centerline axis of the third port is perpendicular to the common axis of the first and second ports.

12. The device of claim 11, wherein:

the opening of the connecting portion comprises a second centerline axis; and

the 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.

13. The device of claim 10, wherein:

the first port comprises a male luer connector; and

the second port comprises a female luer connector.

14. The device of claim 10, wherein:

the first port comprises a male luer connector; and

the second port comprises a needleless access port.

15. The device of claim 10, wherein the proximal end of the valve element comprises a continuous enlarged surface.

16. The device of claim 10, wherein the fluid director comprises a needleless access port that is in fluid communication with the first port, the second port, and the third port in each of the first, second, and third rotational positions of the fluid director.

17. The device of claim 10, wherein the valve element comprises an elastomeric material.

18. The device of claim 11, wherein:

the fluid director comprises a recess;

the opening of the connecting portion comprises a protrusion; and

the 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.
