Abstract

A device for subcutaneous administration of a medicament to a patient is disclosed, including a cannula housing with an interior chamber, a cannula connected to the housing and being in flow communication with the chamber, a flexible tubing having a first end and a second end, the first end being coupled to the housing such that the tubing is in flow communication with the chamber, and wherein, the second end carries a source coupling for coupling the tubing to the medicament. The tubing between the first and the second end is folded for forming a configuration with at least two essentially parallel courses of tubing, the tubing is secured in the configuration by a first holder device arranged between the first and second end of the tubing; and that the tubing can be displaced in relation to the first holder device for varying the length of the courses of tubing.

Claims

1. A device for subcutaneous supply of a medicament to a patient, comprising:

a cannula housing with an interior chamber;

a cannula connected to the cannula housing and being in flow communication with the interior chamber;

a flexible tubing having a first end and a second end, wherein the tubing is, at its first end coupled to the cannula housing, said tubing being in flow communication with the interior chamber; and

wherein the tubing carries a source coupling, at its second end, by which the tubing can be coupled to a source for said medicament;

wherein the tubing is folded and forms a configuration with essentially parallel courses of said tubing;

wherein the device comprises a first and a second holder device said essentially parallel courses running between said first holder device and said second holder device, said holder devices each defining guides therein for securing the tubing to said holder devices, each holder device receiving at least two of said courses of tubing; and

wherein the first holder device is freely slidable along the tubing towards the second holder device by movement of the tubing along said guides in the first holder device.

2. A device according to claim 1, wherein the first holder device is configured as a housing with at least two bores that form said guides.

3. A device according to claim 2, wherein the second holder device is arranged between the first and second ends of the tubing;

and wherein the second holder device can be displaced along the tubing in a direction towards the first holder device.

4. A device according to claim 3, wherein the second holder device is configured as a housing with at least two bores that form said guides.

5. The device according to claim 3, wherein the second holder device comprises the source coupling.

6. A device according to claim 1, wherein the second holder device comprises the cannula housing or a coupling for connecting the tubing to the cannula housing.

7. A device according to claim 6, wherein the tubing is received in guides that extend interiorly of the cannula housing.

8. A device according to claim 1, wherein the second holder device comprises the source coupling.

9. A device according to claim 8, wherein the tubing is received in guides that extend interiorly of the source coupling.

10. A device according to claim 1, wherein the tubing is bent for forming at least three essentially parallel courses of tubing.

11. A device according to claim 1, wherein the first holder device and the second holder device comprises two housing parts configured for movement between a first position in which there is access to said guides for introduction into the guides of the tubing transversally to the longitudinal expanse of the guides, and a second position, in which the tubing is fixed against movement out of the guides transversally to the longitudinal expanse of the guides.

12. A device according to claim 1, wherein the guides are configured for being blocked, wherein removal of the tubing by withdrawal of the tubing transversally to the longitudinal direction of the tubing is prevented.

13. A device according to claim 1, wherein the first holder device or the second holder device comprises two housing parts configured for movement between a first position in which there is access to said guides for introduction into the guides of the tubing transversally to the longitudinal expanse of the guides, and a second position, in which the tubing is fixed against movement out of the guides transversally to the longitudinal expanse of the guides.

14. The device according to claim 1, wherein the tubing is slidably received in said first holder device.

15. The device according to claim 1, wherein said first holder device is releasably lockable to said second holder device.

16. A medicament supply device including a flexible tubing for supplying a medicament to a first end thereof with a cannula housing coupling for connecting said device to a cannula housing that has an interior chamber and a cannula connected to said cannula housing in flow communication with the interior chamber, from a second end thereof having a source coupling wherein the tubing can be coupled to a source of said medicament, wherein said tubing is, between the first and the second end folded, forming a configuration with essentially parallel courses of said tubing, wherein the device includes a first and, a second holder device, said essentially parallel courses running between said first holder device and said second holder device, said holder devices each defining guides therein for securing the tubing to said holder devices, each holder device receiving at least two of said courses of tubing;

and wherein the first holder device is freely slidable along the tubing towards the second holder device by movement of the tubing along said guides in the first holder device.

17. A device according to claim 16, wherein the first holder device is configured as a housing with at least two bores that form said guides.

18. A device according to claim 17, wherein the second holder device is arranged between the first and second ends of the tubing;

and wherein the second holder device can be displaced along the tubing in a direction towards the first holder device.

19. A device according to claim 18, wherein the second holder device is configured as a housing with at least two bores that form said guides.

20. A device according to claim 16, wherein the second holder device comprises the cannula housing coupling.

21. A device according to claim 20, wherein the tubing is received in guides that extend interiorly of the cannula housing coupling.

22. A device according to claim 16, wherein the second holder device comprises the source coupling.

23. A device according to claim 22, characterised in that the tubing is received in guides that extend interiorly of the source coupling.

24. A device according to claim 16, wherein the tubing is folded for forming at least three essentially parallel courses of tubing.

25. A device according to claim 16, wherein the first holder device and the second holder device-comprises two housing parts configured for being movable between a first position in which there is access to said guides for introduction into the guides-of the tubing-transversally to the longitudinal expanse of the guides;

and a second position in which the tubing is fixed against movement out of the guides transversally to the longitudinal expanse of the guides.

26. A device according to claim 16, wherein the guides are configured for being blocked, wherein removal of the tubing by withdrawal of the tubing transversally to the longitudinal direction of the tubing is prevented.

27. A device according to claim 16, wherein the first holder device or the second holder device comprises two housing parts configured for movement between a first position in which there is access to said guides for introduction into the guides of the tubing transversally to the longitudinal expanse of the guides;
