Arrangement in electronically controlled injection devices
First Claim
1. A portable or hand-held injection device comprising a container and an injectable preparation, or components for a preparation, an outlet for the preparation and displacing means at least able to displace the preparation through the outlet, wherein the device further comprises a position sensor designed to emit one or more position signals indicative of its orientation and a control unit designed to receive the position signals and issue one or more operation signals for the device, the operation signals being one or more signals controlling the displacing means during readying of the device, so that activation of the displacing means is prevented unless the device is oriented in a predetermined direction.

Abstract
In an electronically controlled injection device for the administering of one or more injections from an injection cartridge, the readying of the device for administrating and the subsequent administering therefrom are controlled by an electronic control unit. This control unit comprises a position or attitude sensor which transmits signals to the control unit such that said readying of the device optionally cannot take place unless the longitudinal axis of the injection cartridge is oriented in a predetermined direction.

14. An injection device, comprising:
- an injection cartridge containing an injectable preparation or components for a preparation which is positioned in a holder and has a rear end,
a piston provided at the rear end of the injection cartridge that is displaceable forward by a piston rod, an electronic control unit that readies the injection device after positioning said cartridge in the holder, wherein said electronic control unit comprises a position sensor that emits position signals controlling the control unit during the readying of the device, so that forward movement of the piston rod is prevented unless a longitudinal axis of the injection cartridge is oriented in a predetermined direction. - View Dependent Claims (15, 16, 17, 18, 19)
