Abstract

Insertion System ( 2 ) and an Insertion kit is disclosed, the Insertion System comprising a housing ( 4 ) with a wall ( 6 ) defining a cavity ( 8 ), an actuator element ( 10 ), a first part ( 12 ) and a second part ( 14 ), the first part comprising a subcutaneous element ( 16 ) and a first base element ( 18 ) with at least one base plate engagement element ( 20 ), the second part comprising a needle hub ( 22 ) and at least one Insertion needle ( 24 ) secured to the needle hub with the second part movably arranged from a first position to a second position relative to the housing along an Insertion axis (X), wherein the housing comprises at least one first coupling element ( 28 ) for releasably securing the Insertion System to an inserter device, and wherein the actuator element comprises an outer part ( 32 ) external to the housing such that manual actuation of the actuator element in relation to the housing is enabled.

First claim

The invention claimed is:

1. An insertion system for insertion into skin comprising:
a housing comprising a wall defining a cavity, and at least one first coupling element capable of releasably securing the insertion system to an inserter device,
a first part comprising a subcutaneous element and a first base element with at least one base plate engagement element,
a second part comprising a needle hub and at least one insertion needle secured to the needle hub, wherein the second part is moveable from a first position to a second position relative to the housing along an insertion axis;
an actuator element comprising an outer part external to the housing such that manual actuation of the actuator element in relation to the housing is enabled, wherein at least a part of the actuator element moves radially outward relative to the insertion axis when the second part is moved to the second position such that at least one insertion needle is inserted into the skin.

2. The insertion system according to claim 1 , wherein the housing further comprises at least one second coupling element, wherein said at least one second coupling element releasably secures the insertion system to a base plate.

3. The insertion system according claim 1 , wherein the actuator element engages with the second part such that the actuator element is configured to move the second part from the first position to the second position.

4. The insertion system according to claim 1 , wherein the actuator element is released from the second part in the second position at least partly via the radially outward movement of the actuator element.

5. The insertion system according to claim 3 , wherein the actuator element comprises at least one engagement part that engages the second part.

6. The insertion system according to claim 1 , wherein the insertion system comprises a spring member configured to move the second part from the second position to the first position or a third position in a retraction direction.

7. The insertion system according to claim 1 , wherein the outer part of the actuator element comprises an annular member encircling the housing.

8. The insertion system according to claim 1 , wherein the housing wall has at least one slit parallel to the insertion axis.

9. The insertion system according to claim 1 , comprising a plurality of first parts including a primary first part and a secondary first part.

10. The insertion system according to claim 1 , wherein the outer part of the actuator element comprises a first grip element encircling at least a part of the housing.

11. The insertion system according to claim 10 , wherein the actuator element comprises a first arm and second arm connected to and extending from the first grip element, the first arm and the second arm extending through at least one opening in the wall of the housing.

12. The insertion system according to claim 1 , wherein the actuator element comprises an inner part and at least a first arm connecting the inner part and the outer part, the first arm extending through a first opening in the wall of the housing.

13. An insertion kit comprising an insertion system according to claim 1 and an inserter device comprising at least one coupling element, wherein said coupling element releasably secures the inserter device to the insertion system.

14. The insertion kit according to claim 13 , comprising a base plate having an adhesive surface and comprising at least one cannula locking element, wherein said cannula locking element locks or engages the first part of the insertion system to the base plate.

15. An insertion kit comprising an insertion system according to claim 1 and a base plate having an adhesive surface and comprising at least one cannula locking element, wherein said cannula locking element locks and engages the first part of the insertion system to the base plate.

16. An insertion system for insertion into skin comprising:
a housing comprising a wall defining a cavity and at least one first coupling element for releasably securing the insertion system to an inserter device,
a first part comprising a subcutaneous element and a first base element with at least one base plate engagement element,
a second part comprising a needle hub and at least one insertion needle secured to the needle hub, wherein the second part is moveable from a first position to a second position relative to the housing along an insertion axis,
an actuator element comprising an outer part external to the housing such that manual actuation of the actuator element in relation to the housing is enabled, wherein at least a part of the actuator element moves radially outward relative to the insertion axis when the second part is moved to the second position, wherein when the insertion system is placed adjacent to skin, the at least one insertion needle is inserted into the skin.

17. The insertion system according to claim 16 , wherein the housing comprises at least one second coupling element for releasably securing the insertion system to a base plate.

18. The insertion system according claim 16 , wherein the actuator element engages with the second part such that the actuator element is configured to move the second part from the first position to the second position.

19. The insertion system according to claim 16 , wherein the actuator element is released from the second part in the second position at least partly via the radially outward movement of the actuator element.

20. The insertion system according to claim 19 , wherein the actuator element comprises at least one engagement part for engaging the second part.

21. The insertion system according to claim 16 , wherein the insertion system comprises a spring member configured to move the second part from the second position to the first position or a third position in a retraction direction.

22. The insertion system according to claim 16 , wherein the outer part of the actuator element comprises an annular member encircling the housing.

23. The insertion system according to claim 16 , wherein the housing wall has at least one slit parallel to the insertion axis.

24. The insertion system according to claim 16 , comprising a plurality of first parts including a primary first part and a secondary first part.

25. An insertion kit comprising an insertion system according to claim 16 and an inserter device comprising at least one coupling element for releasably securing the inserter device to the insertion system.

26. The insertion kit according to claim 25 , comprising a base plate having an adhesive surface and comprising at least one cannula locking element for locking or engaging the first part of the insertion system to the base plate.

27. An insertion kit comprising an insertion system according to claim 16 and a base plate having an adhesive surface and comprising at least one cannula locking element for locking or engaging the first part of the insertion system to the base plate.
