14. The injection device of claim 13, wherein the second holding part includes a lower part and an upper part wherein the upper part and lower part are configured to snap-lock and lock the pen device.

15. The injection device of claim 13, wherein the first element of the first holding part and a second element of the pen device are adapted to engage in a snap-lock.

16. The injection device of claim 13, wherein the first element of the first holding part and a second element of the pen device are adapted to engage in a threaded type lock.

17. The injection device of claim 13, wherein the first element of the first holding part includes a cavity and a second element of the pen device includes a protrusion, wherein the cavity and protrusion are adapted to engage in the snap-lock.

18. The injection device of claim 13, wherein the durable or pre-filled pen device is a pre-filled pen.

19. The injection device of claim 13, wherein the durable or pre-filled pen device is a durable pen.

20. An injection device system adapted for injecting a pre-filled pen device along an injection direction defining an injection axis, comprising: a housing adapted for being positioned on skin of a human subject, wherein said housing includes a tubular element having a first end for being positioned on the skin and a second upper opening opposite the first end; and a movable element movably arranged relative to the housing between a retracted position and an injection position, wherein the movable element includes a holder adapted for holding the pen device, wherein the movable element includes a first portion arranged to slide inside the first tubular element of the housing, a second portion arranged to slide at a first outer surface of the housing, and a connection portion connecting the first portion with the second portion, wherein the movable element extends out of the upper opening of the first tubular element, the pre-filled pen device containing a medicine, wherein the holder includes a first holding part closest to the first end of the housing and a second holding part, wherein the first holding part has a first element for engaging and fixing the pen device in a correct position for injection, and the second holding part is configured to lock the pen device and prevent the pen device from moving relative to the movable element of the injection device, wherein the pen device has an outer circumference, wherein a second element engages with the first element of the first holding part and fixing the pen device in the correct position for injection is located at the outer circumference.

21. A holder adapted for holding a pen device for use in an injection device, comprising: a first holding part and a second holding part, wherein the first holding part has a first element for engaging and fixing the pen device in a correct position for injection, and the second holding part is configured to lock the pen device and prevent the pen device from moving relative to the holder.

22. A method of injecting a durable or pre-filled pen device, comprising: providing an injection device according to claim 13, wherein the movable element is in the retracted position; arranging the pen device containing a medicine in the first holding part and engaging the first and second elements for fixing the pen device in the correct position for injection; arranging the pen device in the second holding part and locking the pen device to prevent the pen device from moving relative to the movable element of the injection device, positioning the injection device at the skin of a human subject; and pushing a release mechanism on the injection device, whereby the movable element moves to said injection position and the medicine of the pen device is injected.

Description

[0039] These drawings are by no means limiting the scope of the present invention and are only intended to guide the skilled person for better understanding of the present invention.

[0040] FIG. 1 illustrates an injection device (10) as described in WO2015/014363, see in particular FIGS. 18-23 and corresponding text in the description. As shown the syringe holder (314) of FIGS. 18-23 of WO2015/014363 has been replaced by a holder (12) adapted for holding the pen device (not shown), wherein a first holding part (16) is shown with a threaded type lock (18) for engagement of a pen device (not shown). Further a second holding part (14) as part of the holder (12) is configured to lock the pen device and prevent the pen device from moving relative to the movable element of the injection device. Such second holding part (14) is also illustrated in WO2015/131903, see for instance FIG. 4a, 7a-e, and 8a-d and corresponding text in the description. Further shown is the holder (11) adapted for holding the pen device, which holder (11) can be used in connection with any injector device, such as autoinjector devices, for securing best possible patient compliance.

[0041] FIG. 2 illustrates an injection device (20) as described in WO2015/014363, see in particular FIGS. 18-23 and corresponding text in the description. As shown the syringe holder (314) of FIGS. 18-23 of WO2015/014363 has been replaced by a holder (32) adapted for holding the pen device (22), wherein a first holding part (28) is shown with a cavity (24) for engagement of a protrusion (24) of the pen device (22). Further a second holding part (30) as part of the holder (32) is configured to lock the pen device and prevent the pen device from moving relative to the movable element of the injection device. The second holding part (30) is more detailed described in WO2015/131903, see for instance FIG. 4a, 7a-e, and 8a-d and corresponding text in the description. The two identical injector devices are shown with the pen device inserted but not engaged on top and when the pen device is engaged so that protrusion (24) is engaged and fixed in cavity (26), and wherein the holder (30) has locked the pen device (22) at bottom.

[0042] FIG. 3 illustrates an injection device system (40) wherein a pre-filled pen device (42) is fixed by snap-lock in first holding part (48) and locked by second holding part (44), wherein the first (48) and second holding part (44) are part of the holder (46) adapted to hold and keep the pen device locked in the correct position as part of the injection device (50) for injection into human skin.
