Tubing assemby
A tubing assembly for use with a fluid delivery system has a first fluid line having a distal end and a proximal end for connecting to a first fluid source, and a second fluid line having a distal end and a proximal end for connecting to a second fluid source. The tubing assembly further has a third fluid line having a distal end and a proximal end, and a connector assembly for connecting the distal end of the first fluid line and the distal end of the second fluid line to the proximal end of the third fluid line. A tubing holder receives at least a portion of the third fluid line. The tubing holder has a first portion and a second portion movable relative to the first portion to selectively block fluid flow through the third fluid line.

2. The tubing assembly of claim 1 , further comprising a locking mechanism to reversibly lock the first portion and the second portion of the tubing holder in the second, closed position.
3. The tubing assembly of claim 1 , wherein the hinge is a living hinge.
4. The tubing assembly of claim 1 , wherein at least one of the first portion and the second portion of the tubing holder has a recessed cavity for receiving the at least the portion of the third fluid line.
5. The tubing assembly of claim 1 , wherein the distal end of the third fluid line has a connector port for connecting to a patient fluid path set.
6. The tubing assembly of claim 1 , wherein at least one of the distal end of the first fluid line and the distal end of the second fluid line is releasably coupled with the connector assembly.
7. The tubing assembly of claim 1 , wherein at least one of the distal end of the first fluid line and the distal end of the second fluid line is non-releasably coupled with the connector assembly.
8. The tubing assembly of claim 1 , wherein at least one of the first filling port and the second filling port has a one-way valve.
9. The tubing assembly of claim 1 , further comprising a fourth fluid line in fluid communication with the first filling port, and a fifth fluid line in fluid communication with the second filling port.
10. The tubing assembly of claim 9 , wherein the hinge comprises a first hinge portion and a second hinge portion, wherein the second portion of the tubing holder has a first section connected to the first portion of the tubing holder by a first hinge portion and a second section connected to the first portion of the tubing holder by a second hinge portion.
11. The tubing assembly of claim 10 , wherein the first section and the second section are independently movable between a first, open position and a second, closed position.
12. The tubing assembly of claim 11 , wherein, in the second, closed position of the first section of the second portion of the tubing holder, the at least the portion of the third fluid line is pinched or folded by the first section of the second portion and the first portion of the tubing holder to block the fluid flow through the third fluid line.
13. The tubing assembly of claim 11 , wherein, in the second, closed position of the second section of the second portion of the tubing holder, at least a portion of at least one of the fourth fluid line and the fifth fluid line is pinched or folded by the second section of the second portion and the first portion of the tubing holder to block fluid flow through the at least one of the fourth fluid line and the fifth fluid line.
14. The tubing assembly of claim 1 , wherein the first connector and the second connector of the tubing holder are configured for connecting the tubing holder to an outlet of a first syringe and an outlet of a second syringe, respectively.
15. A tubing assembly for use with a fluid delivery system, the tubing assembly comprising:
a first fluid line having a distal end and a proximal end;
a first connector with a first filling port connected to the proximal end of the first fluid line;
a second fluid line having a distal end and a proximal end;
a second connector with a second filling port connected to the proximal end of the second fluid line;
a third fluid line having a distal end and a proximal end;
a connector assembly for connecting the distal end of the first fluid line and the distal end of the second fluid line to the proximal end of the third fluid line; and
a tubing holder for receiving at least a portion of the third fluid line, the tubing holder having a first portion and a second portion connected to the first portion by a hinge such that the second portion is movable relative to the first portion between a first, open position and a second, closed position, the tubing holder further comprising the first connector with the first filling port and the second connector with the second filling port wherein the proximal end of the first fluid line is fluidly connected to the first connector and the proximal end of the second fluid line is fluidly connected to the second connector;
wherein, in the first, open position, the third fluid line is unobstructed to allow fluid flow through the third fluid line and the first filling port and the second filling port are closed to prevent fluid flow through the first filling port and the second filling port, and
wherein, in the second, closed position, the at least the portion of the third fluid line is obstructed to block fluid flow through the third fluid line.
