DRUG DELIVERY INJECTION PEN WITH ADD-ON DOSE CAPTURING AND DISPLAY MODULE

摘要

A drug injector (1) comprising expelling means for expelling a dose of drug from a reservoir, a release member (13) for releasing the drug expelling means, and an actuation member (33) adapted to be moved by a user between an initial, intermediate and actuated position in which the release member is moved to release the drug expelling means. The injector further comprises an electronic capturing system for capturing data representing a dose of drug to be expelled, and a switch (38) for starting initialization of the data capture system, the switch being actuated when the actuation member is positioned in its intermediate position. A spring (34) provides a biasing force against movement of the actuation member between its initial and intermediate position. Thereby the electronic data capturing system is allowed to initialize during the actuation member's movement between the intermediate and the actuated position.

1. A drug delivery system, comprising:
expelling device for expelling a dose of drug from a reservoir, an electronically controlled capturing system for capturing data representing a property related to the amount of drug expelled from a reservoir by the expelling means, switch device for starting initialization of the capturing system, a release member for releasing or driving the expelling means and adapted to be moved between:
an initial position, andan actuated position in which the expelling means is released or driven, an actuation member adapted to be moved by a user between:
an initial position,an intermediate position in which the switch means is actuated to start initialization of the capturing system, andan actuated position in which the release member is actuated, actuation biasing means providing a biasing force against movement of the actuation member between its initial and intermediate position,whereby the capturing system is allowed to initialize during the actuation member's movement between the intermediate position and the actuated position.
