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 more than one thereto-conductive sheet portions, each sheet portion comprising at least a first layer comprising a metal foil between a second internal layer comprising a biocompatible plastic material and a third external layer comprising a biocompatible plastic material, wherein the first layer has a thickness of less than 60 microns and more than 30 microns and wherein the second layer has a thickness of less than 75 microns and more than 45 microns.

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

3. The container according to claim 1, wherein the first layer has a thickness of 45 microns±

8%.

4. The container according to claim 1, wherein the second layer comprises a PVC film.

5. The container according to claim 1, wherein the second layer has a thickness of 60 microns±

10%.

6. The container according to 1, wherein the biocompatible plastic material comprises an oriented polyamide film.

7. The container according to claim 6, wherein the third layer has a thickness of less than 35 microns and more than 15 microns.

8. The container according to claim 7, wherein the third layer has a thickness of 25 microns±

10%.

9. The container according to claim 1, wherein the container comprises two sheets as at least a part of the more than one sheet portions and further comprises a fluid channel formed between said two sheets.

10. The container according to claim 9, preformed according to a shape wherein the fluid channel comprises at least one flat surface for contacting a heating plate of a warming device.

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

12. 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.

13. The container according to claim 4, wherein the PVC film is a medical grade PVC.

14. 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.

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

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

17. A process for the manufacture of a container according to claim 1, comprising the step of providing plural sheet portions, with each sheet portion comprising at least a first layer comprising a metal foil and at least a second internal layer comprising a biocompatible plastic material, and a third external layer comprising a biocompatible plastic material, wherein the first layer has a thickness of less than 60 microns and more than 30 microns and wherein the second layer has a thickness of less than 75 microns and more than 45 microns.

18. The process according to claim 17, wherein a fluid channel is formed by application of vacuum or mechanical press using pressure.
