Abstract

The present invention relates to an organizer for releasably accommodating components of blood tube sets for different extracorporeal blood treatment options, in particular for dialysis methods, by means of a blood treatment apparatus, as well as methods for manufacturing and preparing an organizer of the invention.

Claims

1. An organizer for a blood treatment apparatus, comprising:

a main body;

a plurality of blood tubes

to be used for a plurality of blood treatments

selected from the group consisting of hemofiltration, hemodialysis, hemodiafiltration, slow-continuous ultrafiltration, membrane plasma separation, and high-volume hemofiltration; and

a fastening element for releasably fastening portions of the blood tubes on the organizer, the fastening element comprising;

a first receiving portion including a first depression for releasably accommodating a portion of a first one of the blood tubes;

a first tab that closes a periphery of the first depression, wherein the first tab has an elastic configuration that allows the first tab to be bent in order to remove the portion of the first one of the blood tubes from the first receiving portion;

a second receiving portion including a second depression for releasably accommodating a portion of a second one of the blood tubes; and

a second tab that closes a periphery of the second depression, wherein the second tab has an elastic configuration that allows the second tab to be bent in order to remove the portion of the second one of the blood tubes from the second receiving portion,

wherein a fixation means positioned between the first tab and the second tab connects the first tab and the second tab to other portions of the fastening element.

2. The organizer according to claim 1, wherein the organizer has an integral configuration.

3. The organizer according to claim 1, wherein at least one of the first tab and the second tab includes a portion that protrudes from other portions of the fastening element to facilitate raising of the tab via a user'"'"'s finger.

4. The organizer according to claim 3, wherein at least one of the first receiving portion and the second receiving portion comprises inclined surfaces.

5. The organizer according to claim 1, wherein at least one of the first tab and the second tab is adapted to pivot in relation to other portions of the fastening element.

6. The organizer according to claim 1, wherein the fastening element is a first fastening element, and wherein the organizer further comprises one or more additional fastening elements with the same structure as the first fastening element.

7. The organizer according to claim 1, wherein the fastening element further comprises a third receiving portion including a third depression for releasably accommodating a portion of a third one of the blood tubes, and wherein the first tab closes a periphery of the third depression.

8. The organizer according to claim 7, wherein the first depression and the third depression have differing sizes.

9. The organizer of claim 1, wherein the plurality of blood treatments are selected from the group consisting of hemofiltration, hemodialysis, hemodiafiltration, slow-continuous ultrafiltration, membrane plasma separation, and high-volume hemofiltration.

10. The organizer according to claim 1, wherein the fixation means comprises a weld spot.

11. The organizer of claim 1, wherein the fixation means is a rotatable connection.

12. The organizer of claim 1, wherein the blood tubes that are not used during the selected one of the plurality of blood treatments are releasable from the organizer.

13. The organizer of claim 1, wherein each of the plurality of blood tubes includes a connection element configured to connect the respective blood tube to the blood treatment apparatus for only a specified extracorporeal blood treatment option.

14. The organizer of claim 1, wherein the plurality of blood tubes comprises a return line, a filtrate line, a substituate line, and a supply line.

15. The organizer of claim 1, wherein the plurality of blood tubes comprises a return line, a filtrate line, a dialysate line, and a supply line.

16. The organizer of claim 1, wherein the plurality of blood tubes comprises a return line, a filtrate line, a dialysate line, a substituate line, and a supply line.

17. The organizer of claim 1, wherein the plurality of blood tubes comprises a return line, a filtrate line, and a supply line.
