Abstract

A fluid connection for use between a reservoir and a cannula part of a medical device is provided. The fluid connection includes a tube of rigid material. The tube has a first end operably connected to the reservoir and a second end operably connected to the cannula part. The tube is operably attached to a surface plate of the medical device.

Claims

1. A fluid connection for use between a reservoir and a cannula part of a medical device, the fluid connection comprising:

a tube of rigid material, the tube having a first end operably connected to the reservoir and a second end operably connected to the cannula part, the tube being operably attached to a surface plate of the medical device.

2. A fluid connection according to claim 1, wherein the fluid connection is fastened to the surface plate by a holding part.

3. A fluid connection according to claim 1, wherein the tube comprises metal or plastic.

4. A fluid connection according to claim 3, wherein the tube comprises a hollow needle.

5. A fluid connection according to claim 1, wherein the tube has a diameter or maximum cross-section less than or equal to about 1 mm.

6. A fluid connection according to claim 1, wherein the tube has at least one pointed end protruding from a holding part.

7. A fluid connection according to claim 6, wherein the tube has a blunt end.

8. A fluid connection according to claim 6, wherein the pointed end of the tube forms a connector needle forming an inlet to a connector part and when pushing a reservoir towards the inlet, the connector needle penetrates a membrane completely covering a first opening of the connector part.

9. A fluid connection according to any of the claims 1, wherein the tube comprises a single piece.

10. A fluid connection according to claim 9, wherein the tube is bent at an angle greater than 0 degrees in at least one position.

11. A fluid connection according to claim 10, wherein the tube is bent in an angle greater than 0 degrees in at least two positions.

12. A fluid connection according to claim 11, wherein the angles of the two positions are identical.

13. A fluid connection according to claim 1, wherein the tube is stationary in relation to the surface plate after the tube has been attached to the surface plate.

14. A fluid connection according to claim 1, wherein the length of a fluid path provided by the connection is maximally about 3 cm.

15. A fluid connection for use between a reservoir and a cannula part of a medical device, the fluid connection comprising:

a tube of rigid material, the tube having a first end operably connected to the reservoir and a second end operably connected to the cannula part;

a holding part configured to secure at least a portion of the tube therein;

a membrane surrounding the first end of the tube to protect the first end; and

a sealing portion connected to the holding part and surrounding the second end.

16. The fluid connection according to claim 15, wherein the tube is bent at an angle greater than 0 degrees in at least one position.

17. The fluid connection according to claim 15, wherein the medical device further comprises a surface plate and the fluid connection is operably connected to the surface plate.

18. The fluid connection according to claim 15, wherein the first end is pointed to form a connector needle.

19. The fluid connection according to claim 15, wherein the holding part comprises a single molded part.

20. The fluid connection according to claim 15, further comprising a cover for covering the holding part with the tube secured in the holding part.
