Abstract

A tubing set includes a length of tubing having at least a section thereof that is fabricated to function with an infusion pump. The tubing set further preferably includes a first valve that is removably connected to the length of tubing on a first end thereof. The first valve is preferably in a closed state when disconnected from the length of tubing. The tubing set also preferably includes a second valve on a second end thereof. The second valve is preferably in a closed state until connected to another fluid path component. The tubing set is preferably suitable for use in an MR environment. A method of replacing at least a first infusion pump in connection with a patient with at least a second infusion pump includes the steps: closing a length of patient tubing connected to a patient to prevent backflow of blood therethrough, the patient tubing being in fluid communication at a first end thereof with a length of administration tubing, the administration tubing being in operative connection with the first infusion pump and being in fluid connection with a source of fluid, the patient tubing being in fluid connection with a patient catheter at a second end thereof; disconnecting the patient tubing from the administration tubing; connecting an intermediate length of tubing to the administration tubing, the intermediate tubing including at least a section thereof that is fabricated to function with the second infusion pump; placing the second infusion pump in operative connection with the intermediate tubing; removing the first infusion pump from operative connection with the administration tubing; and connecting the intermediate tubing to the patient tubing.

Claims

1. A tubing set for use with a fluid delivery device, the tubing set comprising:

a first valve removably connected to the first end of the length of tubing, the first valve being in a closed state when disconnected from the length of tubing; and

a second valve on a second end of the length of tubing, the second valve being in a closed state until connected to another fluid path component.

2. The tubing set of claim 1 wherein the first valve comprises a housing and a closing member that is biased in a closed position when the first valve is removed from connection with the length of tubing.

3. The tubing set of claim 1 wherein the closing member extends outside of the housing when in a closed position.

4. The tubing set of claim 1 wherein the tubing set is suitable for use in an MR environment.

5. The tubing set of claim 1 wherein the second valve is biased in a closed position when connected to the length of tubing.

6. The tubing set of claim 5 wherein the second valve comprises a housing and a closing member that is biased in a closed position.

7. The tubing set of claim 6 wherein the closing member of the second valve extends outside of the housing when in a closed position.

8. A method of replacing at least a first fluid delivery device for delivering fluids to a patient with at least a second fluid delivery device, the first fluid delivery device being in fluid connection with a length of patient tubing connected to a patient at one end and removably connected to a length of administration tubing at another end, the administration tubing being in fluid connection with a source of fluid and in operative connection with the first fluid delivery device, the method comprising:

disconnecting the patient tubing from the administration tubing;

connecting a length of intermediate tubing to the administration tubing, the intermediate tubing comprising at least a section thereof that is operable to function with the second fluid delivery device;

placing the second fluid delivery device in operative connection with the intermediate tubing;

removing the first fluid delivery device from operative connection with the administration tubing; and

connecting the intermediate tubing to the patient tubing.

9. The method of claim 8, further comprising:

priming the intermediate tubing with fluid after connection thereof with the administration tubing.

10. The method of claim 9 wherein the intermediate tubing is primed using the first fluid delivery device.

11. The method of claim 10 wherein the intermediate tubing is primed using the second fluid delivery device.

12. The method of claim 8 wherein the intermediate tubing is connected to the patient tubing via a valve that is removably connected to the intermediate tubing, the valve being in a closed state when disconnected from the intermediate tubing.

13. The method of claim 8 wherein the second fluid delivery device is more suitable than the first fluid delivery device for use in an MR environment.

14. The method of claim 8, further comprising:

pumping fluid using the second fluid delivery device.

15. The method of claim 12, further comprising:

disconnecting the patient tubing from the intermediate tubing while leaving the valve connected to the patient tubing.

16. The method of claim 15, further comprising:

disconnecting the administration tubing from the intermediate tubing;

connecting the patient tubing to the administration tubing via the valve; and

placing the first fluid delivery device in operative connection with the administration tubing.

17. The method of claim 16, further comprising:

disinfecting the valve prior to connecting the valve to the administration tubing.

18. The method of claim 17 wherein the valve comprises a housing and a closing member that is biased in a closed position when the valve is removed from connection with the intermediate tubing.

19. The method of claim 18 wherein the closing member extends outside of the housing when in a closed position.

20. The method of claim 8 wherein a first plurality of fluid delivery devices are replaced by a second plurality of fluid delivery devices, the second plurality of fluid delivery devices being more suitable than the first plurality of fluid delivery devices for use in an MR environment.

21. The method of claim 8 wherein the first fluid delivery device is a multi-channel fluid delivery device that is replaced by a plurality of fluid delivery devices, the plurality of fluid delivery devices being more suitable than the multi-channel fluid delivery device for use in an MR environment.

22. The method of claim 8 wherein a first plurality of fluid delivery devices are replaced by a multi-channel fluid delivery device, the multi-channel fluid delivery device being more suitable than the first plurality of fluid delivery devices for use in an MR environment.

23. The method of claim 8 wherein the first fluid delivery device is an infusion pump and the second fluid delivery device is an MR-compatible infusion pump.

26. The method of claim 25 wherein the port of the administration tubing is part of a Y-connector.

28. The system of claim 27 wherein the tubing set further comprises a second valve connected on the second end of the length of tubing, the second valve being in a closed state when connected to the length of tubing until connected to another fluid path element.

29. The system of claim 27, further comprising an adapter to place an administration tubing set of another infusion pump in a free flow state after the other infusion pump has been removed from operative connection with the administration tubing set.

30. The system of claim 27 wherein the length of tubing further comprises at least one Y-connector to provide a connection port.

24. A method of substituting at least a first fluid delivery device for delivering fluids to a patient with at least a second fluid delivery device for a period of time, the first fluid delivery device being in fluid connection with a length of patient tubing connected to a patient at one end and removably connected to a length of administration tubing at another end, the administration tubing being in fluid connection with a first source of injection fluid and in operative connection with the first fluid delivery device, the method comprising:
