A computerized electro-mechanical drug delivery device configured to deliver at least one dose of two or more medicaments. The device comprises a control unit. An electro-mechanical drive unit is operably coupled to the control unit and a primary reservoir for a first medicament and a secondary reservoir for a fluid agent, e.g. a second medicament. An operator interface is in communication with the control unit. A single dispense assembly is configured for fluid communication with the primary and the secondary reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile, the control unit is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

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.

An all-in-one insulin pen includes a handheld housing that houses a glucose testing module, an insulin delivery module, a wireless communication module, and a microcontroller. The glucose testing module tests a one-time glucose concentration of a patient. The insulin delivery module automatically administers an insulin bolus to the patient based at least in part on the one-time glucose concentration.

Disclosed is a method for controlling an auto injector and an auto injector for administering a medicament from a cartridge having a first cartridge end and a second cartridge end and having a cartridge outlet at the first cartridge end, the cartridge comprising a cartridge compartment with a first cartridge subcompartment containing a first medicament component of the medicament and a second cartridge subcompartment containing a second medicament component of the medicament. The auto injector comprises: a housing; a cartridge receiver; a cartridge sensor; a drive module; an orientation sensor; and a processing unit.

The present invention relates to a medicament delivery device comprising a housing, an actuation mechanism (40) arranged inside said housing, the actuation mechanism comprising a plunger rod (42) arranged to act on a stopper (18) of a medicament container (16); an actuator (84) arranged slidable and connected to the plunger rod (42) for acting on the stopper (18) when said actuator (84) is operated by displacing it in a longitudinal direction of the actuation mechanism (40); an activator (104) rotatably arranged for activating said actuation mechanism and for setting a dose; said activator (104) comprising a generally tubular activator sleeve (148), said activator sleeve (148) comprises protrusions (150) arranged to interact with ledges (90) on said actuator (84) such that said activator sleeve (148) is rotated when said actuator (84) is operated. The invention is characterised in a first audio generating mechanism comprising audio generating elements (94) and said protrusions (150), which protrusions (150) are arranged to cooperate with said audio generating elements (94) for generating an audible signal after said operation for delivering a dose.

An add-on device adapted to be releasably mounted on a drug delivery device, the add-on device comprising an outer assembly with an add-on dose setting member adapted to be coupled to the outer housing of a pen housing, as well as an inner assembly engaging the pen dose setting member and being in rotational engagement with the add-on dose setting member during dose setting. The invention addresses the issue of preventing transfer of movement from the add-on dose setting member to the inner assembly during dose expelling, which in accordance with the invention is realized by rotationally de-coupling the inner and outer assembly during dose expelling.

A device for extracting a fluid from an ampoule, comprising a plunger body (2) arranged for enclosing an ampoule (3), and a syringe body (4) movable relative to the plunger body (2). The syringe body (4) comprises a piston member (6) and an outer tubular casing (8) concentrically arranged around the piston member (6). The piston member (6) comprises an insertion end (10), receivable within the plunger body (2) and arranged for insertion in the ampoule (3), an ejection end (12) attached to the outer tubular casing (8), and a lumen (14) extending between the insertion end (10) and the ejection end (12). The plunger body (2) and the syringe body (4) form an actuating arrangement of the device (1) arranged to move the piston member (6) through the ampoule (3) during operation and forcing a fluid from the ampoule (3) through the lumen (14).

An auto injector (4) for administering injection of a medicament from a cartridge containing the medicament, the auto injector (4) comprising: a housing (6); a cartridge receiver (300) with a cartridge receiver compartment (302) configured to receive a cartridge assembly (600), with at least one cartridge retention member (808), when inserted through a cartridge receiver opening (301) along a longitudinal axis (L) in a receiving direction; wherein the cartridge receiver (300) has a passage (316) through which the at least one cartridge retention member (808) travels at least in the receiving direction, and a member (312) preventing movement beyond a retention position in a direction opposite of the receiving direction; an elongated ejector (200) that is configured with: an ejector support face (204) for supporting the cartridge or cartridge assembly (600), a longitudinal ejector slot (228) extending towards the ejector support face (204) from an ejector rest portion (206); wherein the elongated ejector (200) is suspended to move along the longitudinal direction and is spring-loaded in the direction opposite of the receiving direction; and an ejector lock (212) supported for turning at least a fraction of a revolution and maintained in a longitudinal position relative to the housing (6); wherein the ejector lock (212) has a ejector lock support portion (214) that is configured to align with and slide along the longitudinal ejector slot (228) at a first angle and to be brought to align with the ejector rest portion (206) at a second angle.
