The present invention provides a drug injection device () comprising a first element () and a second element () configured to undergo unidirectional movement relative to each other corresponding to an action performed on or by the drug injection device (), wherein the first element () comprises a plurality of serially disposed protrusions (), wherein the second element () comprises first and second deflectable transducers () configured for sequentially cooperating with the plurality of protrusions (), and wherein a processor () is electrically connected with the first and second deflectable transducers () to register activation signals, wherein the protrusion configuration is so disposed on the first element () and the first and second deflectable transducers () are so disposed on the second element () that a second activation signal generated by the second deflectable transducer () is delayed relative to a first activation signal generated by the first deflectable transducer () as the first element () and the second element () move relative to each other, and wherein the processor () is configured to provide a) a first control action if a time delay between the first and second activation signals is above or equal to a pre-defined value, and b) a second control action if said time delay is below said pre-defined value.

Drug injection device with deflectable transducers

A rotary sensor assembly, comprising a first sensor part with a plurality of position sensor segments, and a second sensor part with a grounded contact in contact with a position sensor segment. For a current incremental rotational position a contact is in contact with an un-powered current-position sensor segment, with the neighbour segments being in a powered state. When the contact is rotated to a powered next-position position sensor segment, the next-position sensor segment becomes a new current-position sensor segment. Electronic circuitry is adapted to detect that the new current-position sensor segment is grounded and that the first and second sensor parts thereby have been rotated one increment relative to each other, and subsequently change the state of the former current-position sensor segment from un-powered to powered and the state of the new current-position sensor segment from powered to un-powered.

Rotary sensor assembly with low-power feature

Drug delivery device adapted to receive a drug-filled cartridge comprises a piston drive member for expelling a dose of drug from a loaded cartridge, a motor for driving the piston drive member, a rechargeable electric power source, an electrical connector allowing an external connector of a power source to be connected for recharging the power source, and a controller for controlling operation of the motor. The controller is adapted to detect a condition indicative of an external power source being connected to the electrical connector and subsequently disable the expelling assembly to thereby prevent that drug can be expelled from a loaded cartridge when an external power source has been connected to the electrical connector.

Motorized drug delivery device with charging safety feature

A drug delivery system () comprising first () and second reservoir units () with first and second identifiers (), and a main unit () adapted to receive either of the first () and second reservoir units () in a mounted position. The main unit () comprises drug expelling means having dose setting means () comprising a rotational dose setting member allowing a user to set a desired dose size for the given drug, the dose size being set in fixed increments for a given state. The drug expelling means has a first state in which an increment corresponds to a first volume of drug, and a second state in which an increment corresponds to a second volume of drug, wherein the drug expelling means is set in the first state by means of the first identifier when a first reservoir unit is mounted, and the drug expelling means is set in the second state by means of the second identifier when a second reservoir unit is mounted.
