Injection Device with Electronic Detecting Means
First Claim
1. An injection device for injecting a dose of drug, the injection device comprising:
- a dose setting mechanism being operable to set a desired dose, operation of said dose setting mechanism causing energy to be stored in a spring member,an injection mechanism comprising a piston rod adapted to cooperate with a piston positioned in a cartridge containing a drug to be delivered in order to cause a set dose to be delivered from the cartridge via the injection device, said injection mechanism being driven by releasing energy previously stored in said spring member during dose setting,means for electronically detecting the amount of a set dose and/or means for electronically detecting the amount of an injected dose, andelectronic display means for displaying a set dose and/or an injected dose to a user.

Abstract
An injection device (1) for injecting a dose of drug, e.g. insulin for diabetes treatment, in which energy is stored in a spring member (9, 24) during dose setting. The stored energy is released and used for driving an injection mechanism during injection of a previously set dose. The injection device (1) further comprises means for electronically detecting the amount of a set dose and/or means for electronically detecting the amount of an injected dose. The electronic detecting means allows storage and/or logging of data relating to injections performed using the injection device (1).
