Abstract

An assembly comprising a drug delivery device and an add-on device adapted to be releasably mounted thereon, the drug delivery device comprising a rotatable dose setting member with an outer surface and at least one axially oriented drive groove. The add-on device comprises a drive portion adapted to be mounted in engagement with the dose setting member and comprises a drive structure adapted to engage a drive groove and being biased in a radially inwards direction. This arrangement allows the drive structure to rotationally slide on the dose setting member outer surface and into engagement with the drive groove(s).

Description

[0001] The present invention generally relates to medical devices associated with easy and efficient installation and operation of user-installable add-ons. Background technique [0002] In the disclosure of the present invention reference is mainly made to a drug delivery device for use eg in the treatment of diabetes by subcutaneous delivery of insulin, however, this is only an exemplary use of the present invention. [0003] Drug delivery devices for subcutaneous injections have greatly improved the lives of patients who must self-administer drugs and biologics. Such drug delivery devices may take a variety of forms including simple disposable devices which are simply ampoules with injection means, or they may be durable devices suitable for use with prefilled cartridges. Regardless of their form and type, they have proven to be important adjuncts in helping patients self-administer infusible drugs and biologics. They also greatly assist caregivers in administering infusib...
