A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.

An electrical information device configured to communicate information related to a medicament delivery performed by a medicament delivery device is presented. The device includes at least one information communication unit configured to communicate the information, and at least one power providing arrangement including at least one power source, at least one electrical switch and at least one switch lock member. The at least one switch lock member being configured to be movable in an axial direction from a first position to a second position by an axial movement of at least one triggering member of the medicament delivery device, to cause a change of state of the at least one electrical switch in the second position, thereby providing electrical power to the at least one information communication unit from the at least one power source, and to be locked in the second position, such that the change of state of the electrical switch is maintained.

An auto injector for administering injection of a medicament from a cartridge containing the medicament, includes a housing, a cartridge receiver with a cartridge receiver compartment configured to receive a cartridge assembly including at least one cartridge retention member when the cartridge assembly is inserted through a cartridge receiver opening along a longitudinal axis in a receiving direction, an elongated ejector including an ejector support face for supporting the cartridge or the cartridge assembly and a longitudinal ejector slot extending towards the ejector support face from an ejector rest portion, wherein the elongated ejector is suspended to move along the longitudinal direction and is spring-loaded in the direction opposite of the receiving direction, and an ejector lock supported for turning at least a fraction of a revolution and maintained in a longitudinal position relative to the housing.

A method of administering subcutaneous treatment to a patient is provided. The method includes delivering, by a needle-free injection device, a first volume of a treatment at a first location on a surface of a body of the patient; detecting a movement of the needle-free injection device relative to the first location; determining, from the movement of the needle-free injection device relative to the first location, a second location of the needle-free injection device relative to the first location; determining a second volume of the treatment to deliver at the surface of the body of the patient at the second location; and delivering, by the needle-free injection device, the second volume of the treatment at the second location on the surface of the body of the patient.

The present disclosure relates to a dose detection system for use in combination with a medication delivery device in which a dose setting member rotates relative to an actuator during dose delivery. The dose detection system includes a module which is removably attached to the medication delivery device. The module includes a dosing component attached to the actuator during dose delivery. The dosing component includes a light source and a light sensor. A sensed element is attached to the dose setting member and includes surface features detectable by the light sensor.

The present disclosure relates to integrated systems, methods and apparatuses for assisting individuals in managing acute life-threatening conditions. A system in accordance with the current disclosure may comprise an electronic circuit configured to be attached to a container of a medication and one or more devices in communication with the electronic circuit in a private network. In an aspect, the one or more devices may work in concert to determine the safety level of an individual based on predetermined usage settings. In some aspects, the system may be configured to determine whether a medication would expire before its manufactured expiry date. In another aspect, the system may assist an individual in locating a medication. In a further aspect, the system may determine whether an individual is having an anaphylactic reaction. In some aspects, the system may detect a known allergen and alert the individual.

A medicament delivery device is presented having a tubular housing comprising a distal end and a proximal end; a medicament container arranged with a medicament delivery member and placed in the housing, a cap removably arranged on the proximal end of the housing and configured to cover the delivery member; a drive mechanism configured to act on the medicament container to expel the medicament through the medicament delivery member upon the drive mechanism is triggered; an activation member arranged coaxially movable in relation to the housing, associated with the drive mechanism and comprising a proximal tubular portion which extends from the proximal end of the housing and wherein for triggering the drive mechanism the activation member is axially moved towards the distal end of the housing after removing the cap from the housing. The proximal tubular portion of the activation member has a resilient element arranged with friction.
