Abstract

A set includes a medicament delivery device with a dose delivery activation mechanism that is configured to adjust the medicament delivery device from an inactive state to an active state in which a dose is deliverable, and a cover. The cover is mechanically attached to the medicament delivery device prior to use of the medicament delivery device, and is configured to cover at least a part of the dose delivery activation mechanism so that a user is restrained from prematurely activating the medicament delivery device. The cover is configured to be movable in a distal direction to uncover the part of the dose delivery activation mechanism to activate the medicament delivery device during use of the medicament delivery device.

First claim

1 . A set comprising:
a medicament delivery device with a dose delivery activation mechanism configured to adjust the medicament delivery device from an inactive state to an active state in which a dose is deliverable; and a cover mechanically attached to the medicament delivery device prior to use of the medicament delivery device, the cover being configured to cover at least a part of the dose delivery activation mechanism so that a user is restrained from prematurely activating the medicament delivery device, and the cover being configured to be movable in a distal direction to uncover the part of the dose delivery activation mechanism to activate the medicament delivery device during use of the medicament delivery device.

2 . The set according to claim 1 , wherein the cover is detachable from the medicament delivery device.

3 . The set according to claim 1 , wherein the medicament delivery device and the cover comprise form-fitting engagement devices that enable releasable attachment of the cover to the medicament delivery device prior to use of the medicament delivery device.

4 . The set according to claim 3 , wherein the form-fitting engagement device of the cover comprises one, two or more wings configured to be deflected outwardly with respect to a longitudinal axis extending through the medicament delivery device.

5 . The set according to claim 3 , wherein a detaching device is configured to detach the cover from the medicament delivery device by outwardly deflecting the one, two or more wings for removal of the cover.

6 . The set according to claim 5 , further comprising a detaching element that is attachable or pre-attached to the medicament delivery device, and
the detaching element comprises the detaching device.

7 . The set according to claim 6 , wherein the detaching element is a cartridge container.

8 . The set according to claim 7 , wherein the cartridge container is configured to be attached to the medicament delivery device, and the detaching device is configured to detach the cover from the medicament delivery device while or after the cartridge container is attached to the medicament delivery device.

9 . The set according to claim 1 , wherein the dose delivery activation mechanism comprises a dose setting assembly to manually set a dose.

10 . The set according to claim 9 , wherein the dose setting assembly comprises a knob and the knob is rotated to set the dose.

11 . The set according to claim 1 , wherein the cover is rotationally or axially constrained with respect to the medicament delivery device in an assembled state of the set.

12 . The set according to claim 1 , wherein an inner shape of the cover is complementary to an outer shape of at least a part of the medicament delivery device housing the dose delivery activation mechanism.

13 . The set according to claim 1 , wherein the medicament delivery device is part of a pen-type injector,
or a separate element is provided to prevent a premature moving of a knob or an injection button, relative to a housing before the separate element is removed.

14 . The set according to claim 1 , wherein the cover is configured to cover at least a part of the dose delivery activation mechanism so that a user is restrained from activating the medicament delivery device, prior to preparing the medicament in a container cartridge.

15 . A method for avoiding a premature dose setting on a medicament delivery device, comprising:
attaching a cover to the medicament delivery device to cover a dose delivery activation mechanism of the medicament delivery device so that a user is restrained from prematurely setting a dose before the medicament delivery device is used, and so that the cover is movable in a distal direction to uncover the dose delivery activation mechanism to activate the medicament delivery device during use of the medicament delivery device.

16 . The set according to claim 1 , wherein the medicament delivery device and the cover comprise one, two or more snap-fitting connections that enable releasable attachment of the cover to the medicament delivery device prior to use of the medicament delivery device.

17 . The set according to claim 3 , wherein the form-fitting engagement device of the cover comprises one, two or more wings configured to be deflected outwardly in a radial direction with respect to a longitudinal axis extending through the medicament delivery device.

18 . The set according to claim 7 , wherein the cartridge container is configured to be screwed to a housing of the medicament delivery device and the detaching device is configured to detach the cover from the medicament delivery device while or after the cartridge container is screwed to the medicament delivery device.

19 . The set according to claim 9 , wherein the dose setting assembly comprises a knob that is rotatable in one direction to increase the dose and in an opposite direction to decrease the dose.

20 . The set according to claim 1 , wherein the cover is configured to cover at least a part of the dose delivery activation mechanism so that a user is restrained from activating the medicament delivery device prior to mixing two or more components of a medicament in a container cartridge.
