Abstract

The present invention relates to a heating device for one or more components of an extracorporeal circuit of a blood treatment device, in particular of a dialyzer, an adsorber or a filter, wherein the heating device has at least one reception region for the named component and at least one heating element for heating the component located in the receiver, wherein the heating device has a plurality of layers, with at least one layer being a flexible layer or elastically deformable layer.

First claim

1 . A heating device for one or more components of an extracorporeal circuit of a blood treatment device, in particular of a dialyzer, a filter or an adsorber, wherein the heating device has at least one reception region for the named component and at least one heating element for heating the component located in the receiver, characterized in that the heating device has a plurality of layers, with at least one layer being a flexible layer or an elastically deformable layer.

2 . A heating device in accordance with claim 1 , characterized in that the heating device has at least one elastically deformable layer and at least one flexible layer.

3 . A heating device in accordance with claim 1 , characterized in that the heating device has at least one rigid layer.

4 . A heating device in accordance with claim 3 , characterized in that the rigid layer has a Young's modulus of 700 N/mm 2 or more.

5 . A heating device in accordance with claim 1 , characterized in that the heating device has at least one rigid layer, at least one elastically deformable layer and at least one flexible layer.

6 . A heating device in accordance with claim 5 , characterized in that the elastically deformable layer is arranged between the rigid layer and the flexible layer.

7 . A heating device in accordance with claim 1 , characterized in that the heating device has at least a or the named elastically deformable layer whose compressive force at 25% compression is in the range from 0.01 N/mm 2 to 0.7 N/mm 2 .

8 . A heating device in accordance with claim 1 , characterized in that the heating device has at least a or the named flexible layer whose maximum bending resistance with respect to the width of the film is at 6.75 N/mm 2 /mm or less.

9 . A heating device in accordance with claim 1 , characterized in that the elastically deformable layer has a greater thickness than the rigid layer and/or than the flexible layer.

10 . A heating device in accordance with claim 1 , characterized in that the flexible layer comprises silicone, polyimide, carbon or aluminum, in particular an aluminum film, or comprises one or more of these components.

11 . A heating device in accordance with claim 1 , characterized in that the elastically deformable layer is formed from rubber or foam, in particular as silicone foam, or comprises one or both of these components.

12 . A heating device in accordance with claim 3 , characterized in that the rigid layer consists of plastic, in particular PP, PET, aluminum or hard foam or comprises one or more of these components.

13 . A heating device in accordance with claim 1 , characterized in that the wall of the reception region is formed by the flexible layer or by the rigid layer or by the elastic layer.

14 . A heating device in accordance with claim 1 , characterized in that the elastic layer or the flexible layer is formed by a floating support.

15 . A heating device in accordance with claim 1 , characterized in that at least one component of an extracorporeal circuit, in particular a dialyzer, a filter or a tube, is received in the receiver.

16 . A heating device in accordance with claim 15 , characterized in that the outer dimension of the component corresponds to the inner dimension of the receiver or exceeds it.

17 . A heating device in accordance with claim 1 , characterized in that the heating element is arranged between two of the named layers or in at least one layer of the heating device; and/or in that the heating element is arranged in the flexible layer.

18 . A blood treatment device, in particular a dialysis machine, having at least one heating device in accordance with claim 1 .
