A drug cartridge includes: a cylinder 11 having a cylindrical cylinder columnar space extending in a longitudinal direction; a gasket 13 supported in the space so that the gasket is movable in the longitudinal direction; a drug 14 held in the space and at least including a liquid first component; and a first temperature sensor and an RF tag 16 arranged on a side surface of the cylinder. The RF tag 16 stores drug information that includes at least information indicating a type of the drug, and wirelessly transmits at least the information indicating the type of the drug and first temperature information indicating a temperature detected by the first temperature sensor in response to an instruction from outside.

The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose-cartridge and permit a user to set the delivery dose. The injector may include a housing, a piston rod adapted to operate through the housing, a dose dial sleeve located between the housing and the piston rod, and a drive sleeve located between the dose dial sleeve and the piston rod. The dose dial sleeve may have a helical thread of first lead and the drive sleeve may have a helical groove of second lead. The first lead of the helical thread and the second lead of the helical groove may be the same.

A medicament delivery device is presented having a drive configured to act on a medicament container for expelling a medicament; a holder configured to hold said drive in a pre-tensioned state; an activator configured to interact with said holder for releasing said drive from the pre-tensioned state; wherein the device further includes a feedback mechanism configured to interact both with said holder and with said drive for generating an audible and/or tactile and/or visual signal indicating that the medicament has been completely expelled.

An auto injector is provided by which a fixed dose of a medicament can be injected as self-treatment, and by which needle exposure to an accessible position, injection of the medicament and retraction of the needle to an inaccessible position is automatically performed as a continuous sequence, after the auto injector is triggered. Solutions to improve the functionality of the retraction of the needle and the general experience of the use, are also provided.

The disclosure relates to an injection device for expelling of a number of preset or user-selectable doses of a medicament. The injection device includes an elongated housing extending along an axial direction and configured to accommodate a cartridge containing the medicament and having a bung sealing a proximal end of the cartridge, a windup expelling mechanism, and a dose setting mechanism. The dose setting mechanism includes a handle , a dose tracking member, and a limiter. The dose tracking member is rotatable relative to the housing within a range of positional states and operatively connectable to the handle for tracking a rotation thereof. The limiter is operationally engageable with the dose tracking member and a trigger of the windup expelling mechanism for blocking actuation of the trigger when the dose tracking member is in one of a number of predetermined sections of the range of positional states.

The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose cartridge and permit a user to set a delivery dose. An injector may include a housing, a cartridge containing a medicinal product, the cartridge being retained within the housing, means for selecting a dose of the medicinal product to be expelled, and means for expelling the selected dose of the medicinal product. The housing may be a unitary housing within which the means for selecting the dose and the means for expelling the selected dose are moveably retained. Alternatively, the injector may include a housing, a piston rod, an insert located in the housing and through which the piston rod may rotate, ratchet means, a dose dial sleeve, a drive sleeve, a button located on the drive sleeve and rotatable with respect to the drive sleeve, and clutch means which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.

A medication delivery device and/or dosing mechanisms suitable for use in medication delivery devices, in particular in pen-type injectors, preferably having a dose setting system and a drive device enabling the administration of a medicinal product from a single- or multi-dose medication cartridge.

A data collection device comprises: a first portion having one or more features configured for attaching of the first portion to a dosage knob of an injection device; a second portion rotatably coupled with the first portion, wherein at least part of the second portion is movable axially relative to the first portion; a sensor arrangement configured to detect rotation of the first portion relative to the second portion; and a processor arrangement configured to, based on said detected movement, determine a medicament amount expelled by the injection device, wherein the coupling arrangement is configured to provide a non-permanent coupling between the first portion and the dosage knob of the injection device.

The present invention provides a power unit (1) for a drug delivery device as well as methods for providing and mounting the power unit (1) in the drug delivery device. The power unit (1) comprises a first interface member (30) extending along a reference axis and comprising a hollow body (31) and a first engagement structure (35), a second interface member (10) comprising a tubular structure (11) extending at least partially through the hollow body (31) and having a skirt (12), and a second engagement structure (14) configured for releasable engagement with the first engagement structure (35), and a torsion spring (20) comprising a first end portion (23) being attached to the first interface member (30) and a second end portion (22) being attached to the second interface member (10), the torsion spring (20) being pre-strained to induce a relative rotational motion between the first interface member (30) and the second interface member (10). The first interface member (30) and the second interface member (10) are configured for relative motion along the reference axis from a first relative axial position in which the first engagement structure (35) and the second engagement structure (14) are engaged to prevent the relative rotational motion between the first interface member (30) and the second interface member (10) to a second relative axial position in which the first engagement structure (35) and the second engagement structure (14) are disengaged. In the first relative axial position of the first interface member (30) and the second interface member (10) the torsion spring (20) is accommodated in a user inaccessible space (39) defined by the hollow body (31) and the skirt (12).

Implementations of the present disclosure are directed to a module for attachment to an injection device that includes a flexible carrier foil configured to be attached to a surface of the injection device independent of a geometry of the surface, at least one light emitting diode attached to the flexible carrier foil in a first position and configured to emit a light signal in a direction based on the first position through a transparent wall of the injection device, at least one photodiode attached to the flexible carrier foil in a second position relative to the first position, the at least one photodiode being configured to detect at least a portion of the light signal from a direction based on the second position and being configured to emit an electrical signal based on the light signal to a microprocessor, and wherein the microprocessor is configured to receive the electrical signal emitted by the photodiode and to determine the position of a stopper and the amount of the fluid within the injection device based at least in part on the electrical signal.
