Abstract

The present invention relates to a multilayer fluid heat exchanger container comprising a thermo-conductive sheet, said sheet comprising at least a first layer comprising a metal foil and at least a second layer comprising a biocompatible plastic material, a multilayer sheet for the fluid container and systems for heating or cooling a fluid comprising the container and a fluid heating or cooling device for receiving the container. The present invention further relates to methods for heating or cooling a fluid comprising the step of circulating a fluid through the container and a process for the manufacture of the fluid container.

Claims

1. A multilayer fluid heat exchanger container comprising a thermo-conductive sheet, said sheet comprising at least a first layer comprising a metal foil and at least a second layer comprising a biocompatible plastic material.

2. The container according to claim 1, wherein the first layer comprises aluminium foil.

3. The container according to claim 2, wherein the first layer has a thickness of less than 60 microns and/or more than 30 microns.

4. The container according to claim 3, wherein the first layer has a thickness of 45 microns ±

8%.

5. The container according to any preceding claim 1, wherein the second layer comprises a PVC film, such as a medical grade PVC.

6. The container according to claim 5, wherein the second layer has a thickness of less than 75 microns and/or more than 45 microns.

7. The container according to claim 6, wherein the second layer has a thickness of 60 microns ±

10%.

8. The container according to any preceding claim 1, wherein the sheet further comprises a third layer comprising a biocompatible plastic material, such as an oriented polyamide film.

9. The container according to claim 8, wherein the third layer has a thickness of less than 35 microns and/or more than 15 microns.

10. The container according to claim 9, wherein the third layer has a thickness of 25 microns ±

10%.

11. The container according to claim 1, wherein the container comprises two sheets and further comprises a fluid channel formed between said two sheets.

12. The container according to claim 11, preformed according to a shape wherein the fluid channel comprises at least one substantially flat surface for contacting a heating plate of a warming device.

13. A multilayer sheet for a fluid container as defined in claim 1.

14. A system for heating a fluid comprising a fluid container as claimed in claim 1 and a fluid warming device for receiving the fluid container.

15. A system for cooling a fluid comprising a fluid container as claimed in claim 1 and a fluid cooling device for receiving the fluid container.

16. A method for heating a fluid comprising the step of circulating a fluid through a container as claimed in claim 1.

17. A method for cooling a fluid comprising the step of circulating a fluid through a container as claimed in claim 1.

18. A process for the manufacture of a container according to claim 1, comprising the step of providing a sheet comprising at least a first layer comprising a metal foil and at least a second layer comprising a biocompatible plastic material.

19. The process according to claim 8, wherein a fluid channel is formed by application of vacuum or mechanical press using pressure.
