A drug injection device comprises a main body case, a drug syringe mounting component, a piston, a drive mechanism, a controller, and means for locking the lid during operation of the drug injection device. The main body case has a lid and a base and an injection needle let-in/let-out opening. The drug syringe mounting component is provided inside the main body case, and allows a (filled) drug syringe to be mounted therein. The piston is movable with respect to the drug syringe mounting component. The drive mechanism drives the drug syringe mounting component and the piston. The controller is electrically connected to the drive mechanism. The means for locking the lid during operation of the drug injection device is activated and deactivated by movement of the drug syringe mounting component when the lid is closed.

Lock for drug injection device

The present invention relates to an injection device comprising an optically-based sensor for determining the position or setting of a dose setting member arranged to set a dose to be injected from the injection device. In particular, the present invention relates to an injection device comprising a rotatably mounted member having a plurality of optically coded paths arranged on an outer surface thereof. The rotatably mounted member is operatively connected to the dose setting member and is adapted to rotate with the dose setting member.

Injection device comprising an optical sensor

A device for injecting preparations is controlled by a sealed circuit block () containing integrated sensors () which monitors selected parameters. Two pairs of integrated Hall elements (and) monitors movements relative to a sine formed magnetic field presented along the perimeter of a multipoled magnetized ring (). The Hall elements in each pair are displaced 180&#xb0; magnetically relative to each other and the two pairs of Hall elements are displaced 90&#xb0; magnetically from each other. Each pair is coupled to a differential amplifier () to provide a cosine and a sine signal, respectively. The sine signal is divided by the cosine signal to create a tangent signal as an entrance to a table showing the angle of the movement.
