Abstract

The fluid management system according to the invention is adapted to automatically supply fluid for injection into a patient. The fluid management system comprises a fluid management device, a fluid transfer system and a fluid injector. The fluid management device serves to store and administrate multi dose containers. The fluid transfer system connects the outlet of the containers stored within the fluid management device to the injector and the injector withdraws the fluid via fluid transfer system from the containers and injects the fluid to an administration device at the patient. The fluid management device comprises at least one rotating carousel with the axis of rotation being vertically, at least two container holders attached to the rotating carousel, said container holders being adapted to position a container vertically with the open end of the neck facing downwards and a spike holder mounted below the rotating carousel and oriented such that the spike holder would axially align a spike connected to the spike holder with the axis of the container that is to be spiked and loaded into the container holder.

Claims

1. Fluid management device for automatic supply of fluid for injection into a patient comprising:

at least one rotating carousel with the axis of rotation being vertical;

at least two container holders attached to the rotating carousel and adapted to position a container vertically with the open end of the neck facing downwards; and

a spike holder mounted below the rotating carousel and oriented such that the spike holder would axially align a spike with the axis of a container loaded into the container holder and being in spiking position.

2. The fluid management device of claim 1 comprising two rotating carousels.

3. The fluid management device of claim 1 further comprising one or more container holders not being attached to the rotating carousel.

4. The fluid management device of claim 1 comprising two rotating carousels and two container holders not being attached to the rotating carousel.

6. The fluid management device of claim 1 wherein all container holders attached to the rotating carousel are adapted to hold containers of equal size, or alternatively some container holders are adapted to hold containers of different size than other container holders.

7. The fluid management device of claim 6 wherein one container holder is adapted to hold a container that is smaller in size than the other containers.

8. The fluid management device of claim 2 wherein each rotating carousel is mounted in a separate chamber.

9. The fluid management device of claim 3 wherein each container holder not being attached to the rotating carousel is mounted in a separate chamber.

10. The fluid management device of claim 8 wherein all chambers are mounted to a chassis framework.

11. The fluid management device of claim 8 wherein at least one of the chambers is temperature-controlled.

12. The fluid management device of claim 8 wherein each chamber can be accessed by an individual hinged lid or door.

13. The fluid management device of claim 1 wherein the spike holder is moveably mounted to a linear slide allowing the spike holder to slide in vertical direction.

14. The fluid management device of claim 13 further comprising a central electronic control system adapted to control the rotation of the rotating carousel and the movement of the spike holder.

20. Fluid management system for automatically supplying fluid for injection into a patient comprising a fluid injector, the fluid management device of claim 1, and a fluid transfer system comprising a first transfer tubing with at least two first ends, each of the first ends connected to a spike, and at least two second ends, each second end corresponding to a first end;

a manifold having at least two input openings and one output opening, the second ends of the transfer tubing being connected to the input openings of the manifold;

a second transfer tubin bein connected to the output opening of the manifold with its first end; and

a valve mounted between each first end and second end of the first transfer tubing.

26. The fluid management device of claim 9 wherein all chambers are mounted to a chassis framework.

27. The fluid management device of claim 9 wherein at least one of the chambers is temperature controlled.

28. The fluid management device of claim 9 wherein each chamber can be accessed by an individual hinged lid or door.

5. (canceled)

15. Fluid transfer system comprising

a first transfer tubing with at least two first ends, each of the first ends connected to a spike, and at least two second ends, each second end corresponding to a first end;

a manifold having at least two input openings and one output opening, the second ends of the transfer tubing being connected to the input openings of the manifold;

a second transfer tubing being connected to the output opening of the manifold with its first end; and

a valve mounted between each first end and second end of the first transfer tubing.

16. Fluid transfer system of claim 15, wherein the second end of the second transfer tubing is adapted to be connected to an injector.

17. Fluid transfer system of claim 15, wherein the spike is a vented spike.

18. Fluid transfer system of claim 15, wherein the spike is covered by a sheath.

19. Fluid transfer system of claim 15, wherein the fluid transfer system further comprises data storage means for storing a unique identifier of the fluid transfer system.

21. Method for automatically supplying of fluid for injection into a patient comprising:

providing a fluid management device adapted to house at least one container with fluid in a vertical position with the open end of the neck facing downwards and having a spike holder mounted and oriented such that the spike holder would axially align a spike connected to the spike holder with the axis of the container loaded in the container holder and being in spiking position;

providing a fluid transfer system having a transfer tubing with a first end connected to a spike and a second end adapted to be connected to an injector;

loading at least one container with the open end of the neck facing downwards into the fluid management device, said open end of the neck being covered by a septum;

attaching the spike to the spike holder and the second end of the transfer tubing to an injector;

moving the spike into the septum; and

withdrawing fluid from the container.

22. Method of claim 21 further comprising withdrawing the spike from the septum of the container.

23. Method of claim 22 wherein the withdrawal of the spike from the septum occurs in response to a signal that was triggered because either the spiked container is empty or the maximum in-use time for the container has been reached or the maximum in-use time for the spike has been reached.

24. Method of claim 21 wherein at least two containers are loaded into the fluid management device.

25. Method of claim 24 wherein the fluid management device further has means to position subsequently each of the containers in axial alignment with the spike holder and the method comprises further

moving a second container in a position where it is in axial alignment with the spike holder;

moving the spike into the septum of the second container; and

withdrawing fluid from the second container.
