A dosing device for an injection device, the dosing device including an actuating element for adjusting and/or dispensing a dose from the injection device, a thrust element for generating a forward movement for discharging a dose and a coupling to which the actuating element and the thrust element are coupled such that a rotational movement of the actuating element is transmitted directly to the thrust element and an axial movement of the actuating element is different than an axial movement of the thrust element.

An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

The present disclosure relates to a dose detection system in combination with a medication delivery device. In one aspect, the system includes a module body adapted to be removably attached to the actuator of a medication delivery device, and one or more magnetic sensing elements attached to said module body. The system detects the amount of rotation of a magnetic ring of said one or more dipoles of a medication delivery device relative to the magnetic sensing elements during dose delivery when the module is attached to the device.

A cartridge assembly (200) having a shared fastening features for use with a drug delivery device (202). The cartridge assembly includes a cartridge holder (204), a drug cartridge (206), and a connector (208). The connector may be attached to the drug cartridge. The cartridge assembly further includes a fastening means (210, 212) for fastening to a drug delivery device, and this fastening means is shared between the cartridge holder and the cartridge or between the cartridge holder and the connector. The drug delivery device may be a reusable drug delivery device or a disposable drug delivery device.

The techniques described herein relate to computerized methods and systems of at least one of for generating a single light indication pattern via LEDs for a dose detection system, such as for example, based on a use case type and a battery life status type. The use case types may include pairing, manual synching, and/or dose injection, and the battery life status types may include 1 to 3 different states. Another method and system are for reducing drainage of a battery for a dose detection system by monitoring the continuous activation of the power-on module, and/or alerting the user in a manner for the user to take action. At least some of the information obtained from these techniques may be communicated to a paired remote electronic device, such as a user's smartphone.

An injection device for delivering a predetermined fixed dose of liquid drug, comprising a base member, a piston rod a first tubular member, and a second tubular member.

Various embodiments of a “smart” drug delivery pen are provided which include a drug delivery pen having an inertial sensor or accelerometer. A system is also provided that includes the smart drug pen in conjunction with a data management unit(s) DMU. Various exemplary methods for use of the pens and systems are also described and illustrated.

Data collection devices for attachment to injection devices are disclosed. In one embodiment, the data collection device includes: a body attachable to a dial member of the injection device, a sensor arrangement comprising a sensor and a scale, and a processor. The sensor is configured to detect a rotation of the body relative to a trigger of the injection device. The processor is configured to detect a rotation of the body relative to the trigger. One of the sensor and the scale is arranged in or on the body and wherein the other one of the sensor and the scale is located on the trigger or is rotationally lockable to the trigger configured to detect a rotation of the body relative to the trigger.

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 cartridge containing medicinal product, the cartridge being retained within the housing, means for selecting a dose of medicinal product to be expelled, and means for expelling the selected dose of medicinal product. The housing may be a unitary housing within which the means for selecting a 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 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 with a sensing system to determine at least one of a dose set and a dose delivery. The sensing system is operable to detect relative rotational positions of first and second members of the device which are indicative of at least one of an amount of a dose set and an amount of a dose delivered by operation of the device, and generate outputs correlated to such relative rotational positions. The system includes a wiper coupled to the first member, and a sensing band coupled to the second member for physically contacting the wiper as the second member rotates relative to the first member. A controller electrically communicates with the sensing system to determine, based on the generated outputs of the sensing system, at least one of the amount of the dose set and the amount of the dose delivered by operation of the device.
