Drug delivery injection pen with add-on dose capturing and display module
First Claim
1. A drug delivery system, comprising:
- an expelling device for expelling an amount of drug from a reservoir, comprising;
a setting device allowing a user to set a dose amount of drug to be expelled, andan actuation device for releasing or driving the drug expelling device to expel the set dose amount,an electronically controlled capturing system for capturing data representing a property related to the amount of drug expelled from the reservoir by the expelling device, anda switch device for starting initialization of the capturing system,wherein the actuation device comprises a push button, characterized in that the push button is adapted to be pushed distally, for said releasing or driving of the drug expelling device between;
an initial position,an intermediate position in which the switch device is actuated to start initialization of the capturing system, andan actuated position in which the expelling device is actuated to expel the set dose,whereby the capturing system is allowed to initialize during the push button'"'"'s movement between the intermediate position and the actuated position.

Abstract
Drug injection device (400) comprising expelling means for expelling an amount of drug from a reservoir, the expelling means comprising setting means (411) allowing a user to set a dose to be expelled, and actuation means (413) for releasing the drug expelling means to expel the set dose. The actuation means comprises an actuation member adapted to be moved between an initial position, an intermediate position, and an actuated position in which the expelling means is actuated to expel the set dose. The device further comprises an electronically controlled capturing system (420) for capturing data representing the amount of drug expelled from the reservoir by the expelling means, and switch means for starting initialization of the capturing system when the actuation member is moved to its intermediate position.

13. A drug delivery system, comprising:
-
a drug expelling device for expelling an amount of drug from a reservoir, comprising; a setting device allowing a user to set a dose amount of drug to be expelled, and an actuation device further comprising a push button adapted to be pushed distally for releasing or driving the drug expelling device to expel the set dose amount, an electronically controlled capturing system for capturing data representing a property related to an amount of drug expelled by the drug expelling device, an identifier associated with a member which moves during drug expelling and represents a property related to the amount of drug expelled from a reservoir by the expelling device, the capturing system being adapted to capture the identifier, and a switch device further comprises a push button for starting initialization of the capturing system, the switch device being actuated as the identifier starts to move when the drug expelling means has been released or starts to be driven by the actuation device, wherein dose data representing a property related to the amount of drug expelled from the reservoir by the expelling means is captured when the set dose amount has been expelled or expelling has stopped for a predetermined amount of time. - View Dependent Claims (14, 15)
