Abstract

The invention concerns an insertion device for inserting a medical device into the subcutaneous or intramuscular area of a patient. More specifically, this invention relates to an insertion device comprising pivoting and guiding means for moving a penetrating member from a position, where the penetrating member is not pointing into the direction of insertion, to a position, where the penetrating member is pointing into the direction of insertion. The inserter device comprises a housing (15) encompassing a penetrating member (9), said housing comprising a top section (14) and a lower section (16), wherein said insertion device (1) comprises pivoting means (27, 31, 41, 43) and guiding means (10, 19, 16s, 31s, 18s) providing one or more pivoting movement(s) of the penetrating member (9) from a first position, where the penetrating member (9) is not pointing into the direction of insertion, to a second position, where the penetrating member (9) is aligned with the direction of insertion, to a third position, where the penetrating member (9) protrudes the housing (15) and the penetrating member (9) is aligned in the direction of insertion. The guiding means (10, 19, 16s, 31s, 18s) are adapted to provide a longitudinal movement of the penetrating member (9) from the second to the third position.

Claims

1. An inserter device for inserting a penetrating member into the subcutaneous area or intramuscular area of a patient, said inserter device comprising:

a housing encompassing said penetrating member, said housing comprising a top section and a lower section,

a pivoting means portion and

a guiding member, the pivoting portion and the guiding member providing one or more pivoting movement(s) of the penetrating member from a first position, where the penetrating member is not pointing into the direction of insertion, to a second position, where the penetrating member is aligned with the direction of insertion, to a third position, where the penetrating member protrudes from the housing and the penetrating member is aligned in the direction of insertion, the guiding member is adapted to provide a straight longitudinal movement of the penetrating member from said second position to said third position.

2. An inserter device according to claim 1, wherein said pivoting portion and guiding members provide a fourth position by a straight longitudinal movement where the penetrating element is fully inserted in the patient, said straight longitudinal movement being of the same length or longer than the length of the penetrating member.

3. An inserter device according to claim 1, wherein said pivoting portion comprises at least one shaft and wherein the at least one shaft traverses the top section and the lower section.

4. An inserter device according to claim 3, wherein the shaft consists of one through-going member or the shaft consists of two or more pieces.

5. An inserter device according to claim 3, wherein a device mounting member is attached to said shaft, and the device mounting member and the shaft share the same center of rotation.

6. An inserter device according to claim 1, wherein said pivoting portion comprises one or more pivoting shafts and one or more pivoting members.

7. An inserter device according to claim 6, wherein a first pivoting shaft traverses the lower section and a pivoting member, and the first pivoting shaft is the centre of rotating of said pivoting member.

8. An inserter device according to claim 7, wherein a second pivoting shaft traverses the pivoting member and the device mounting member.

9. An inserter device according to claim 1, wherein said guiding member comprises one or more guiding slots.

10. An inserter device according to claim 9, wherein said guiding slot is provided on the lower section, said guiding slot being parallel to the direction of insertion, and being of the same length or longer than the length of said straight longitudinal movement and said guiding slot is encompassing said shaft, and restricting the length of the longitudinal movement of the shaft and the lower section.

11. An inserter device according to claim 9, wherein the guiding slot is provided within a pivoting member, said guiding slot comprising a bent section towards an upper part of the pivoting member, and a straight section of the same length or longer than the length of said straight longitudinal movement, said guiding slot encompassing and restricting the movement of said shaft.

12. An inserter device according to claim 9, wherein the guiding slot is provided within a vertical section of said device mounting means, the guiding slot is of the same length or longer than the length of said longitudinal movement, said guiding slot encompassing the second pivoting shaft, and restricting the movement of the second pivoting shaft.

13. An inserter device according to claim 1, wherein application of a downward force on the top section into the direction of insertion provides a rotation of the medical device through interactions of a shaft being guided by a guiding slot of the lower section and a guiding slot of a pivoting member, and through interactions of first and second pivoting shafts being guided by the pivoting member and guiding slot on a vertical section of a device mounting member.

14. An inserter device according to claim 6, wherein said guiding member comprises one or more rounded protrusions provided on said device mounting member, said protrusions extending away from the direction of insertion.

15. An inserter device according to claim 14, wherein said guiding member comprises a major protrusion flanked symmetrically by two minor protrusions, said major protrusion being aligned with the penetrating member along an axis perpendicularly to the shaft.

16. An inserter device according to claim 14, wherein the device comprises upper guiding means and lower guiding means, and said upper and lower guiding means are extending from an inner surface of the lower section and the interaction between the protrusions and the upper and lower guiding means provides a rotation of the medical device upon application of a downward force on the top section.

17. An inserter device according to claim 1, wherein the penetrating member comprises a cannula or an introducer needle.

18. An inserter device according to claim 17, wherein the introducer needle is part of the inserter device, and where said introducer needle is removed from a medical device after insertion of the penetrating member.

19. An inserter device according to claim 18, wherein said pivoting portion and guiding member provide a fifth position by a straight longitudinal movement, where the introducer needle is retracted through the penetrating member or into the housing.

20. An inserter device according to claim 1, where the penetrating member is a part of a medical device and the medical device is a sensor, or an infusion part, or a port for injection of a fluid.

21. An inserter device according to claim 1, wherein a central axis of insertion is parallel to a central axis of the insertion device.

22. An inserter device according to claim 1, wherein a central direction of insertion of the penetrating member is either essentially perpendicular to the patient'"'"'s skin surface, or at an insertion angle 0°
