The present disclosure relates to a dose detection system and method for a medication delivery device. The dose detection system may include a dosing component attached to an actuator and rotationally and axially moveable relative to a coupling component attached to a dose setting member. The dose detection system may further comprise a module including an electronic sensor operative to detect a relative rotation of the coupling component and the dosing component to detect a dose delivered by the medication delivery device.

Sensor assembly comprising a first rotary sensor part with a plurality of individual electrically conducting sensor areas arranged in a pattern, a second rotary sensor part arranged rotationally relative to the first portion, the second part comprising a plurality of contact structures adapted to be in contact with conducting sensor areas on the first sensor rotary part. The contact structures are configured to engage and connect different sensor areas as the first and second part of the rotary sensor rotate relative to each, the created connections being indicative of a rotational position between the first and second portions. One of the contact structures is an actuatable contact structure being axially moveable relative to the first portion and having a connected position in which the actuatable contact structure is in contact with a sensor area and a disconnected position in which the actuatable contact structure is not in contact with a sensor area.

A mounting aid for attaching a supplementary device to an injection device, wherein the injection device has an elongated housing extending in an axial direction, the mounting aid comprising a body extending in the axial direction, configured to receive at least a portion of the housing and having at least one radially extending engaging member to engage with a correspondingly shaped engaging member of the housing when in a specific position relative to the housing, and wherein the body comprises a side wall with an abutment face facing in a proximal direction, wherein the abutment face is defined on a plane that is inclined to the axial direction.

The present invention relates to a monitoring device (10) arranged to be operably connected to a medicament delivery device (12), said medicament delivery device (12) comprising a manually operated movable dose activation element (20), said monitoring device (10) comprising an electronic circuit (42), said electronic circuit (42) comprising an optical sensor (68), wherein said optical sensor (68) is positioned in relation to said dose activation element (20) so as to detect a manual operation of said dose activation element (20) from an initial position; said electronics circuit further comprising a vibration sensor (70), wherein said vibration sensor (70) is positioned in relation to said medicament delivery device so as to detect specific vibration spectra produced by the medicament delivery device when said dose activating element (20) is operated, wherein said electronic circuit (42) comprises computing elements capable of correlating the information from the optical sensor (68) with the information from the vibration sensor (70) when said dose activation element (20) is operated in order to register when a correct dose has been set.

The present disclosure relates to a drug delivery device, comprising a housing, a cartridge, the cartridge containing a drug in a quantity sufficient for a plurality of doses of the drug, a bung, the bung being movably retained within the cartridge to dispense a dose of the drug from the cartridge upon movement of the bung with respect to the cartridge, and a drive mechanism, the drive mechanism being operable to transfer a driving force to the bung to dispense the dose of the drug from the cartridge. The drug delivery device is configured such that the maximal driving force which is transferrable to the bung via the drive mechanism varies and is adjusted to the current position of the bung within the cartridge.

The present invention relates to a drug delivery device comprising a dose setting member (70) for setting user variable doses of a medicament and a display for indicating the dose set by the dose setting member (70). The display comprises a number wheel (100), which is rotationally coupled to the dose setting member (70) and is provided with a series of markings on its outer circumference, and at least one prism (90) deviating the image of the markings of the number wheel (100), e.g. by 90°.

The present disclosure is generally directed to a drive mechanism for use in a drug delivery device having a cylindrical cartridge, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The drive mechanism includes a base element, a toothed piston rod, which is guided within and movable relative to the base portion, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod. The toothed piston rod includes multiple rigid rod pieces which are connected by hinges. The rigid rod pieces comprise a flat plate provided with a straight toothed rack.

The invention provides a kit comprising a medical accessory device and a dummy unit. The accessory device comprises first attachment means configured for releasable attachment of the accessory to co-operating second attachment means on an original device having an outer surface defining an original device space envelope. The dummy unit comprises a presentation surface on its external surface, a folded or rolled sheet, as well as dummy attachment means configured for releasable attachment of the accessory device to the dummy unit in co-operation with the first attachment means. By this arrangement the mounting of the accessory device on the original device can be demonstrated on the dummy unit in a simple and effective way.

A medication injection pen, including a housing, a dose set knob (DSK) comprising an internal key, and a dose stop member engaging the dose set knob. Rotation of the dose set knob to set a medication dose causes rotation of the dose stop member with respect to the dose set knob, and when the dose set knob is rotated to a last dose setting position, the dose stop member rotationally abuts the internal key thereby preventing further rotational movement of the dose set knob in a dose setting direction.

A data collection device for attachment to an injection device and for collecting medicament dosage information therefrom.
