1. An injection device adapted for injecting a pen injector device along an injection direction defining an injection axis, comprising: a housing adapted to be positioned on skin of a human subject, wherein said housing includes a tubular element having a first end 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 injector device, wherein the movable element includes a first portion arranged to slide inside the 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 second upper opening of the tubular element, 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 injector device in a correct position for injection, and the second holding part is configured to lock the pen injector device and prevent the pen injector device from moving relative to the movable element of the injection device, and wherein the first element of the first holding part is adapted to engage in a threaded-type lock with a second element of the pen injector device so that the pen injector device screws into the first element to engage with the first holding part.

2. The injection device of claim 1, 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 injector device.

3. The injection device of claim 1, wherein the first element of the first holding part includes an inner thread proceeding about an inner circumference of the first element, and the second element of the pen injector device comprises a corresponding thread engaging element which coincides with the inner thread, and wherein the inner thread and a corresponding thread engaging element are adapted to engage in the threaded-type lock.

4. The injection device of claim 1, wherein the pen injector device is a pre-filled pen injector.

5. The injection device of claim 1, wherein the pen injector device is a pen injector configured to accept replaceable cartridges.

6. An injection device system adapted for injecting pen injector device along an injection direction defining an injection axis, comprising: a housing adapted to be 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 injector device, wherein the movable element includes a first portion arranged to slide inside the 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 second upper opening of the tubular element, wherein the pen injector device contains 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 injector device in a correct position for injection, and the second holding part is configured to lock the pen injector device and prevent the pen injector device from moving relative to the movable element of the injection device, wherein the pen injector device has an outer circumference, wherein a second element of the pen injector device is adapted to engage with the first element of the first holding part to fix the pen injector device in the correct position for injecting and the second element of the pen injector device is located at the outer circumference, and wherein the first element of the first holding part is adapted to engage in a threaded-type lock with the second element of the pen injector device so that the pen injector device screws into the first element to threadedly engage with the first holding part.

7. A method of injecting a pen injector device, comprising: providing the injection device according to claim 1, wherein the movable element is in the retracted position; arranging the pen injector device containing a medicine in the first holding part and engaging the first and second elements for fixing the pen injector device in the correct position for injection; arranging the pen injector device in the second holding part and locking the pen injector device to prevent the pen injector device from moving relative to the movable element of the injection device, positioning the injection device at the skin of the 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 injector device is injected.

DETAILED DESCRIPTION

(5) 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 FIGS. 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.

(6) 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.
