摘要： A supplemental device for attachment to an injection device, the supplemental device having a housing containing at least two electromechanical switches each having an open state and a closed state and a protrusion associated with each switch configured to protrude from the housing so as to contact a rotatable surface of the injection device while the supplemental device is attached to the injection device; and a processor arrangement configured to detect a change in the state of each of the switches; and to determine a direction of rotation of the rotatable surface of the injection device from the detected state changes.

摘要： A data collection device for attachment to an injection device, such as an injector pen, includes a sensor arrangement to detect movement of a movable component of the injection device relative to the data collection device during delivery of a medicament by the injection device, and a processor arrangement configured to, based on said detected movement, determine a medicament dosage administered by the injection device. The processor arrangement may monitor the time that has elapsed since the medicament dosage was administered, and control a display to show the medicament dosage and elapsed time to provide a memory aid to the user. In an example embodiment, the sensor arrangement includes an optical encoder and the movable component includes a plurality of light barrier formations. The movable component may be a number sleeve that provides a visual indication of a dose programmed into the injection device.

摘要： The present disclosure pertains to an assembly for a drug delivery device having a housing part, a piston rod displaceable relative to the housing part, a first sleeve member and a second sleeve member. First and second sleeve members are coupled to the housing part. In an initial state of the assembly the first sleeve member is movable from an initial position to a second position relative to the second sleeve member which allows the piston rod to axially travel from an initial position to a predetermined second position such that the assembly is in a primed state. Moreover, in the primed state of the assembly, with the first sleeve member being in the second position relative to the second sleeve member, first and second sleeve members are permanently rotationally and axially locked to each other by a first engagement feature such that first and second sleeve members together form a sleeve.

摘要： 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.

摘要： A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.

摘要： The present disclosure relates to a drive mechanism for an injection device for setting and dispensing of a dose of a medicament, the drive mechanism including a tubular shaped housing component extending in an axial direction (z) and comprising an inner thread, a tubular shaped display member having an outer thread engaged with the inner thread, and a dose member axially displaceable between a dose setting position (S) and a dose dispensing position relative to the display member, wherein the display member includes at least one blocking member on its outer circumference to axially engage with a blocking structure on an inside facing sidewall portion of the housing component to block an axial displacement of the dose member from the dose setting position (S) towards the dose dispensing position.
