EP4591905A1 — Electronic add-on module and assembly of an electronic add-on module and a drug delivery device

USPTO Abstract

The present disclosure is directed to an electronic add-on module (100) configured for attachment to a drug delivery device and to an assembly comprising a drug delivery device and an electronic add-on module (100). The electronic add-on module may comprise a first portion (101) with a main housing (103) defining a longitudinal axis (X). The module (100) comprises a gripping mechanism allowing attachment to drug delivery device dose dial user interfaces, e.g. a dial grip (G, G'), and/or drug delivery device injection user interfaces, e.g. a dose button (B, B') of varying diameters and shapes. The first portion (101) comprises on an inner side of the main housing (103) at least two elastically deformable arms (118) each having a clamping section (121) which is configured to be elastically, deflected radially outwards with respect to the longitudinal axis (X) from a unstressed, nominal position to a strained deflected position.
