Abstract

The invention concerns a base part for a medication delivery device, the base part comprising a connection part and a moveable part. The moveable part, which moves relative to the connection part, is capable of guiding fluid paths from a medication delivery port to a first cannula or sensor and a second cannula or sensor. The base part also comprises guiding means which can direct each cannula or sensor to its subcutaneous position.

First claim

The invention claimed is:

1. A base part for subcutaneous introduction of a cannula, the base part comprising:
a connection part comprising an inlet opening adapted to receive a first flow of fluid from a delivery part to a first outlet opening, and a second flow of fluid from the delivery part to a second outlet opening, wherein said delivery part comprises a reservoir;
a moveable part, which moves relative to the connection part, the movable part having at least two different positions:
a first position forming a first fluid path from the first outlet opening of the connection part to a first inlet of the moveable part and then to a first cannula or sensor; and
a second position forming a second fluid path from the second outlet opening of the connection part to a second inlet of the moveable part and then to a second cannula or sensor,

wherein the base part comprises a first guiding means for causing a first change in direction of about 15 to about 85 degrees for a distal part of the first cannula or sensor after the moveable part has been moved into the first position, and
a second guiding means for causing a second change in direction of about 15 to about 85 degrees for a distal part of the second cannula or sensor after the moveable part has been moved into the second position.

2. The base part according to claim 1 , wherein the inlet opening is protected by a protective sealing membrane.

3. The base part according to claim 1 , comprising a gasket positioned between the connection part and moveable part wherein the gasket is stationarily positioned relative to the movable part.

4. The base part according to claim 1 , wherein the first cannula and the second cannula comprise a soft and flexible material or a hard and rigid material.

5. The base part according to claim 4 , wherein the first cannula and the second cannula comprise the soft and flexible material.

6. The base part according to claim 5 , wherein the first cannula and the second cannula each comprise an elastomer.

7. The base part according to claim 1 , wherein the first position results in penetration of skin by the first cannula, and wherein the second position results in penetration of skin by the second cannula.

8. The base part according to claim 1 , wherein the first change in direction is about 45 degrees.

9. The base part according to claim 1 , wherein the second change in direction is about 45 degrees.
