Abstract

A fluid management system adapted to automatically supply fluid for injection into a patient is disclosed. The fluid management system includes 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 an outlet of these containers to the injector which withdraws a fluid from the containers via the fluid transfer system and injects the fluid to an administration device at the patient. The fluid management device includes at least one rotating carousel having a vertical axis of rotation, at least two container holders attached to the rotating carousel and adapted to position the container vertically with a septum covered end facing downwards, and a spike holder mounted below the rotating carousel and oriented so the spike holder axially aligns a spike connected to the spike holder with the axis of the container.

Claims

1. A fluid management device for automatic supply of a medical fluid to a fluid injector for injection into a patient, the device comprising:

at least one rotating carousel with a vertical axis of rotation;

at least two container holders each configured for holding a separate corresponding container, wherein the at least two container holders are fixedly attached to the at least one rotating carousel prior to, during, and after spiking, and during supply of the medical fluid to the fluid injector for injection into the patient, wherein each of the at least two container holders positions the corresponding container vertically with a septum covered end of a neck of the corresponding container facing downwards prior to, during, and after spiking, and during supply of the medical fluid to the fluid injector for injection into the patient;

a spike holder mounted below the at least one rotating carousel and oriented such that the spike holder axially aligns a spike with an axis of the corresponding container loaded into the container holder and being held in a spiking position, wherein the spike holder is moveably mounted to a linear slide allowing the spike holder to slide upwards in a vertical direction to spike the corresponding container and to slide downwards in the vertical direction for de-spiking the corresponding container and wherein the spike holder is driven by an automated spiking system; and

a central electronic control system adapted to communicate with the automated spiking system, wherein the central electronic control system comprises a timer that once the corresponding container has been spiked can determine if the corresponding container has exceeded a maximum in-use time, determine if the spike has exceeded a maximum in-use time, or combinations thereof.

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

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

4. The fluid management device of claim 3, wherein all of the separate chambers are mounted to a chassis framework.

5. The fluid management device of claim 3, wherein at least one of the separate chambers is temperature-controlled.

6. The fluid management device of claim 3, wherein each of the separate chambers can be accessed by an individual hinged lid or door.

7. The fluid management device of claim 1, further comprising one or more container holders that are not attached to the at least one rotating carousel.

8. The fluid management device of claim 7, wherein each of the one or more container holders that is not attached to the at least one rotating carousel is mounted in a separate chamber.

9. The fluid management device of claim 8, wherein all of the separate chambers are mounted to a chassis framework.

10. The fluid management device of claim 8, wherein at least one of the separate chambers is temperature controlled.

11. The fluid management device of claim 8, wherein each of the separate chambers can be accessed by an individual hinged lid or door.

12. The fluid management device of claim 1, comprising two rotating carousels and two container holders that are not attached to the two rotating carousels.

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

14. The fluid management device of claim 13, wherein one of the at least two container holders is adapted to hold a container that is smaller in size than other containers.

15. The fluid management device of claim 1, wherein the central electronic control system is adapted to control rotation of the at least one rotating carousel and movement of the spike holder.

16. A fluid management system for automatically supplying a medical fluid for injection into a patient, the system comprising:

the fluid injector and the fluid management device of claim 1, and a fluid transfer system, wherein the fluid transfer system comprises at least a first transfer tubing comprising two tubes, with at least two first ends, each of the at least two first ends connected to each of at least two spikes, and at least two second ends, each of the at least two second ends corresponding to each of the at least two first ends;

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

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

a valve mounted between each of the at least two first ends and the at least two second ends of the first transfer tubing.

17. The fluid management device of claim 1, wherein the central electronic control system is further adapted to monitor a fluid level/volume of the container once the container has been spiked.

18. The fluid management device of claim 17, wherein the fluid level/volume of the container is monitored with fluid level/volume sensors.
