Abstract: An assembly for a drug delivery device is provided, the assembly comprising an actuator which is configured to be operated in order to dispense a dose of medication and a feedback feature being configured to give a feedback signal to a user at the end of a dwell period after the actuator has reached an end position.

Abstract: A drive mechanism of a drug delivery device and a respective drug delivery device for setting and dispensing of a dose of a medicament are presented, where the drive mechanism has an elongated housing extending in an axial direction, a piston rod to operably engage with a piston of a cartridge containing the medicament, a dosing arrangement manually and axially displaceable relative to the housing for setting and dispensing of the dose, and an accessory drive operably engaged with the piston rod to support a manually operated dose dispensing displacement of the dosing arrangement.

Abstract: A drug delivery device, comprises a housing having a longitudinal axis; an axially moveable component that is moveable along the longitudinal axis between a dose dialing position and a dose delivery position when a user operates the device to deliver a dose of drug; an encoder sleeve; an encoder pattern provided on the encoder sleeve, the encoder pattern comprising relatively conductive portions and relatively non-conductive portions that together comprise coded information; a contact-supporting component; and plural electrical contacts provided on the contact-supporting component. The plural electrical contacts contact the encoder pattern when the dose delivery button is in the dose dialing position and wherein the device is configured to move the contact-supporting component relative to the encoder sleeve as the axially moveable component moves from the dose dialing position to the dose delivery position such as to move the electrical contacts into positions where they do not contact the encoder pattern.

Abstract: A method of decoding encoded information is presented where one or more sensors are controlled to periodically check for motion of a movable component of a drug delivery device having encoded information thereon. If motion of the movable component is detected, preventing a first encoded information reading and decoding process from being performed, when motion of the movable component is not detected, performing the first encoded information reading and decoding process.

Abstract: A drug delivery device is presented comprising of a housing, a plurality of contacts, a rod disposed within the housing, and an encoded member configured to be rotatably supported inside the housing, to engage with the rod and to be rotatable with respect to the rod, and to be axially constrained with respect to the housing such that axial advancement of the rod in a first direction relative to the housing causes rotation of the encoded member, wherein the outer surface of the encoded member is provided with a plurality of tracks together forming an encoder, each track comprising conductive segments and non-conductive segments and wherein the encoded member is supported in the housing such that each track is engaged by a respective one of the plurality of contacts.

Abstract: A drug delivery device is presented comprising of a housing, a plurality of contacts, and a cylindrical member configured to be rotatably supported inside the housing, wherein the outer surface of the cylindrical member is provided with a plurality of tracks together forming an encoder, each track comprising conductive segments and non-conductive segments, and wherein the cylindrical member is supported in the housing such that each track is engaged by a respective one of the plurality of contacts.

Abstract: The invention relates to an arrangement for detecting a position of a plunger relative to a bung in a drug cartridge, comprising a proximity sensor located close to a distal end of the plunger facing the bung and aligned to receive light reflected by the bung.

Abstract: A drug delivery device comprising; a housing; a cylindrical member configured to be rotatably supported inside the housing, wherein the outer surface of the cylindrical member is provided with at least first and second tracks together forming an encoder, each track comprising conductive segments and non-conductive segments; and at least first and second groups of contacts configured to engage the first and second tracks respectively at predetermined intervals along the length of the track.

Abstract: A drug delivery device comprising; a housing; a cylindrical member configured to be rotatably supported inside the housing, wherein the outer surface of the cylindrical member is provided with a track comprising a sequence of encoded images; and a sensor directed at the track of the cylindrical member and configured to detect features of the encoded images.
