Abstract

The invention relates to a fluid connection (60) having at least a first and a second opening (13, 12), i.e. an inlet and an outlet, where the first opening (13) forms a fluid connection to a medication supply (6) or the like and the second opening (12) forms a fluid connection to an opening in the body (24) of a separate cannula part (7) and an at least partly sub- or transcutaneous positioned cannula (22). The fluid connection is characterized in that is attached to a surface plate (1) and has the form of a tube (60) made of a rigid material. Further the invention relates to a base part comprising such a fluid connection.

Claims

1. A base part positionable on a patient'"'"'s skin, the base part comprising:

a contact surface for fastening the base part to the patient,

a fastener connecting a medication supply to the base part,

a rigid connection part comprising a fluid connection having at least a first and a second opening, wherein the first opening forms a fluid connection to a medication supply and the second opening forms a fluid connection to an opening in a body of a separate cannula part comprising an at least partly sub- or transcutaneous positioned cannula and

the base part is connectable to the separate cannula part wherein each of the first and second openings is either provided with a sealing or adapted to fit with a corresponding sealing of an adjacent part.

2. A base part according to claim 1, wherein the fluid connection is attached to a surface plate and has the comprises a tube made of a rigid material.

5. A base part according to claim 2, wherein the tube comprises a hollow needle.

6. A base part according to claim 2, wherein the tube has a diameter or maximum cross-section≦

1 mm.

7. A base part according to claim 2, wherein the tube has at least one pointy pointed end protruding from a holding part.

10. A base part according to claim 2, wherein the tube consists of a single piece.

11. A base part according to claim 10, wherein the tube is bent in an angle >

0 degrees in at least one position.

14. A base part according to claim 2, wherein the tube is stationary in relation to the surface plate after the tube has been attached to the surface plate.

16. A base part according to claim 14, wherein at least one of the first and second openings is combined with a sealing material.

17. A base part according to claim 14 wherein each of the first and second openings is provided with means providing a fluid tight and non-contaminated transfer of fluid from a reservoir to the cannula part once the separate cannula part is inserted.

18. A base part according to claim 17, wherein the first opening comprises a septum that is penetrable by a rigid needle and that is reclosable upon retraction of the rigid needle.
