The invention relates to an insertion device comprising—a penetrating member (50) connected to transformation means (52), —a moving part (38) comprising guiding means (39) which guiding means (39) restrict the movement of the transformation means (52) and guide the penetrating member (50) from a fir
The invention relates to an insertion device comprising—a penetrating member (50) connected to transformation means (52), —a moving part (38) comprising guiding means (39) which guiding means (39) restrict the movement of the transformation means (52) and guide the penetrating member (50) from a first to a second position in a first direction, i.e. the direction of insertion, towards the injection site, and—a stationary housing (30) comprising guiding means (32) which guiding means (32) restrict the movement of the moving part (38). The guiding means (32) guide the moving part (38) in a second direction which is linear and different from the first direction i.e. the direction of insertion.

1. An insertion device comprising a penetrating member comprising an insertion needle connected to transformation member, the penetrating member before and during insertion is attached to a body holding a cannula or sensor at a surface of insertion after insertion has taken place,a moving part comprising a first guide member, the first guide member is configured to restrict the movement of the transformation member and guide the penetrating member from a first to a second position in a first direction, the first direction is linear and towards an injection site, anda stationary housing comprising a second guide member configured to restrict the movement of the moving part, the second guide member of the housing is configured to guide the moving part in a second direction which is linear and substantially parallel to a surface on which the stationary housing is mounted during insertion,wherein the insertion device further comprises a well-defined tube that restricts the movement of the penetrating member to a linear movement in the first direction, and wherein the transformation member of the penetrating member is movable in or along the well-defined tube. 2. An insertion device according to claim 1, wherein the housing comprises a retention member retaining the moving part in a start position, the moving part comprises a locking member interacting with the retention member in the start position and an activation part comprises a protrusion interacting with the locking member upon activation. 3. An insertion device according to claim 2, wherein a base part is fastened to a mounting surface and the insertion device comprises a fastener adapted to fasten the insertion device to the base part before insertion and to release the insertion device to the base part upon insertion of the cannula. 4. An insertion device according to claim 3, wherein the fastener comprises: fastening members releasably locking the housing of the insertion device to the base part, andrelease members releasing the housing from the base part after insertion of the penetrating member. 5. An insertion device according to claim 4, wherein the fastening members are flexibly connected to the stationary housing. 6. An insertion device according to claim 5, wherein the moving part is provided with one or more protruding parts that contact with the flexibly connected fastening members and through this contact release the insertion device from the base part. 7. An insertion device according to claim 4, wherein the release members comprise an elastic member in a biased or distorted state which upon release of the fastening member pushes the housing of the insertion device away from the base part. 8. An insertion device according to claim 2, wherein the locking member comprises a hook provided with an inclined surface pointing in a direction opposite to the forward movement of the activation part and the retention member of the housing comprises a part protruding from the housing and is adapted to interact with the hook. 9. An insertion device according to claim 2, wherein the forward movement of the activation part is stopped through contact between the protrusion of the activation part and the retention member for the moving part. 10. An insertion device according to claim 1, wherein the insertion device before insertion of the penetrating member is attached to a base part, the base part can be fastened to the surface where the penetrating member is to be inserted and the penetrating member is brought in contact with or passes through the base part upon insertion. 11. An insertion device according to claim 10, wherein the penetrating member is attached to the body holding the cannula, the body comprising a retention member securing the body and the cannula at the surface of insertion, the retention member interacts with a connector on the base part upon insertion and retains the body of the penetrating member to the base part. 12. An insertion device according to claim 1, wherein the first guide member of the moving part comprises a groove in which the transformation member of the penetrating member can slide. 13. An insertion device according to claims 12, wherein the groove is substantially V-or U-shaped defining a starting point, a middle point and an end point for at least a portion of the penetrating member. 14. An insertion device according to claim 1, wherein the insertion device comprises means to perform the following operations upon actuation of an activation part: loading of a spring;movement of the moving part from a start position to a stop position; andtransformation of said movement of the moving part to an insertion movement of the penetrating member, followed by a retraction movement of a holding means of the penetrating member. 15. An insertion device according to claim 14, further comprising a release member adapted to release the housing from a base part upon insertion of the penetrating member. 16. An insertion device according to claim 1, where the first direction form an angle β to the surface in which the penetrating member is to be inserted, and where 30°<β<90°. 17. An insertion device according to claim 1, wherein an energy storing member provides the energy required for moving the moving part from a start position to a stop position. 18. An insertion device according to claim 1 , wherein the distance from the surface in which the penetrating member is inserted, is obtained by constructing the insertion device comprising an inclining proximal surface.
