The present invention is directed to a pen-type injector equipped with a cartridge holder for a drug delivery device. The cartridge holder has a longitudinal axis and comprises a body for receiving a cartridge, wherein the body comprises at a proximal end engagement means for releasably coupling the cartridge holder to the drug delivery device, a latch member for releasably engaging a cap of the drug delivery device and an alignment element which is visual from the outer side of the body. The alignment element may be an aperture provided in the body and/or a lug which forms the latch member.

A drug delivery system comprises an indicator element and a sensor system. The indicator element is arranged to rotate relative to a reference component and corresponding to a reference axis and comprises a plurality of dipole magnets. The sensor system comprises a plurality of magnetometers arranged non-rotational relative to the reference component and adapted to determine continuous magnetic field values from the plurality of dipole magnets, as well as processor means configured to determine on the basis of measured values from the plurality of magnetometers a rotational position and/or a rotational movement of the indicator element.

The present invention concerns an apparatus (1) for measuring and recording the remaining quantity of medicament in a medicament dosing device (2). The apparatus (1) has a location where the medicament dosing device (2) can be inserted. Combined with that location the apparatus (1) has equipment for measuring and analysing. The apparatus is characterised in that this equipment for measuring and analysing comprises a contact image sensor (3) combined with that location for the medicament dosing device, and a software in connection with the contact image sensor. In addition the object of this invention is the corresponding method for measuring and recording the remaining quantity of medicament in a medicament dosing device (2).

Implementations of the present disclosure are directed to an injection device (102) including a medicament reservoir (103) configured to store a medicament to be expelled by the injection device (102), an acoustic source (122a, 122b, 122c, 122d, 200, 300, 400) configured to generate an acoustic signal including information indicative of an amount of the medicament stored in the medicament reservoir (103), the acoustic signal being transmitted to an external device (104) configured to process the acoustic signal and to extract injection device data.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device in communication with a mobile communication device having a software application to determine a recommended dose based on prior dose data, analyte data, and nutrient data and to generate a report illustrative of a relationship between the medicine data, the health data, and the contextual data.

The disclosure relates to a medicament delivery device, comprising a medicament cartridge adapted to contain a medicament and a stopper slidably arranged within the cartridge. The stopper-comprises a rigid body that is enclosed partially by a soft sealing component.

An apparatus includes a syringe body, a plunger, a cap, and a dose gauge. The syringe body defines a volume configured to contain a medicament. The dose gauge is disposed about at least a portion of a side wall of the syringe body, and defines a window. The cap is coupled to a proximal end portion of the syringe body, and includes an engagement portion. The plunger has a distal end portion configured to move within the volume to convey the medicament. An engagement portion of the plunger is configured to interface with the engagement portion of the cap to prevent rotation of the plunger about a longitudinal axis of the plunger. An outer surface of the plunger includes a series of indicia. At least one of the indicium is visible through the window when the plunger is in a first position within the volume.

A medication delivery device included molded cylindrical barrel having visual marks on the surface of the barrel in the axial direction, a plunger seals the distal opening of the cylindrical barrel, a molded needle hub disposed in the proximal opening of the cylindrical barrel for sealing the needle hub to the barrel. A needle is disposed in the needle hub for communicating liquids by operation of the plunger in the axial direction. The circumferential surface on the flange of the needle hub comprises a colored mark that corresponds to a characteristic of the medication delivery device or its contents.

Systems and methods encourage users to rotate injection sites and avoid lipodystrophy. Sleeves and/or lost-tooth gear dials and/or microswitches in or on injection pens or their caps, on vials, and on other portable devices manually adjust an indicator before or after an injection to show a current or next injection site in accordance with a site rotation plan. Injected medicine packaging and related printed indicia encourage site rotation. Optical devices employing optical mouse or projection technology help locate and/or distribute injection sites within a body area. A mobile phone app tracks injections and locations to select next injection site, and can use imaging to locate a target injection site and optionally diagnose lipodystrophic conditions and record them. Tactile and print media educational tools are presented to help users palpate and identify lipos in body areas having injection sites.

A handheld injection device (10) comprising an needle cannula, a reservoir configured for containing a liquid drug to be dispensed, a piston, a trigger button (22), an elongated, hollow outer housing (20) in which the reservoir is positioned, the needle cannula being in liquid communication with the reservoir and extending from one end of the housing, wherein the injection device further comprises a drive mechanism comprising a spring or a resilient member, the spring or a resilient member being configured to provide a driving force when the trigger button is pressed allowing the piston to be advanced by the drive mechanism thus causing a dose of the liquid drug to be dispensed, wherein the handheld injection device comprises a variable friction system being adapted to apply a variable counter force leveling out the driving force.
