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.

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 member 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 at least one shaft consists of one through-going member or the at least one shaft consists of two or more pieces. 5. An inserter device according to claim 3, wherein a device mounting member is attached to the at least one shaft, and the device mounting member and the at least one 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 center of rotation of said pivoting member. 8. An inserter device according to claim 7, wherein a second pivoting shaft traverses the pivoting member and a device mounting member. 9. An inserter device according to claim 6, wherein said guiding member comprises one or more rounded protrusions provided on a device mounting member, said protrusions extending away from the direction of insertion. 10. An inserter device according to claim 9, 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 extending perpendicular to the one or more pivoting shafts. 11. An inserter device according to claim 9, wherein the device comprises an upper guiding member and a lower guiding member, and said upper and lower guiding members are extending from an inner surface of the lower section and the interaction between the one or more rounded protrusions and the upper and lower guiding members provides a rotation of the penetrating member upon application of a downward force on the top section. 12. An inserter device according to claim 1, wherein said guiding member comprises one or more guiding slots. 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 penetrating member 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 a first pivoting shaft and a second pivoting shaft being guided by the pivoting member and a guiding slot on a vertical section of a device mounting member. 16. An inserter device according to claim 1, wherein the penetrating member comprises an introducer needle extending at least partially through and supporting a medical device, and where the introducer needle is removed from the medical device after insertion of the penetrating member. 17. An inserter device according to claim 16, wherein said pivoting portion and guiding member provide a fifth position by a straight longitudinal movement, where the introducer needle is retracted through the medical device or into the housing. 18. An inserter device according to claim 17, where the medical device is a sensor, a port for injection of a fluid, or an infusion part. 19. An inserter device according to claim 1, wherein a central axis of insertion is parallel to a central axis of the insertion device. 20. 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 of 0°<αins<90°. 21.
