The present disclosure relates to a cartridge holder of an injection device, the cartridge holder comprising a tubular shaped elongated sleeve extending in an axial direction to accommodate a cartridge filled with a medicament, wherein the sleeve (29) comprises: a proximal connecting end to connect with a distal connecting end of a body of the injection device, which body is configured to accommodate a drive mechanism of the injection device and which drive mechanism is operably engageable with a piston of the cartridge, a flange section extending radially outwardly from an outside surface of the sleeve and having a proximally facing abutment face to axially abut with a distal end face of the distal connecting end of the body, at least three protrusions located distally from the flange section, extending radially outwardly from the outside surface of the sleeve and being distributed around the circumference of the sleeve.

A single-use injector having a plunger actuator which is mounted in a housing, which is loaded by a spring energy store, and which can be unlocked by a movable release device. The plunger actuator can be supported by a traction rod mounted in the housing. The movable release device includes a casing housing. The casing housing includes an upper shell and a lower shell, the separation line of which is oriented in the longitudinal direction of the single-use injector. The casing housing has a cornerless cross-section deviating from a circular shape. The housing is anti-rotationally centered in the casing housing.

A drug delivery device is provided for delivering a drug to a target tissue site. The drug delivery device comprises a body comprising a proximal end and a distal end and a chamber disposed therebetween. An upper portion is disposed about the proximal end of the body. A retaining member is disposed within a wall of the body and engageable with the chamber and a plunger is configured for disposal within the upper portion and the chamber. The upper portion is movable about the proximal end of the body to open the chamber such that the plunger is disposed within a passageway defined within the chamber, and movement of the plunger in a distal direction pushes the retaining member such that the drug moves out of the body. Methods are also disclosed.

A medial assembly comprises a logging first unit adapted to be mounted on a drug delivery device second unit from a fully un-mounted to a fully mounted position along a path. The first unit comprises a switch operatable between an off- and an on-state when the first unit is mounted on the second unit, the switch being in the on-state when the first unit is mounted within a first distance from the fully mounted position, and in the off-state when the first unit is mounted outside the first distance from the fully mounted position, and a snap lock operatable from an initial state through an expanded state to a snap-in state when the first unit is mounted on the second unit, the snap lock being in the snap-in state when the first unit is mounted within a second distance from the fully mounted position, the second distance being shorter than the first distance. By this arrangement it is ensured that the switch will be in the on-state before the snap lock is in the snap-in state.

A medication dispenser includes a hollow body having an open first end and a second end opposing the first end. A hollow open-ended tube is coupled to the second end of the hollow body. A vial having one end sealed with a piston and one end sealed with a rupturable element is slidably disposed in the hollow body with the rupturable element being adjacent to one open end of the tube. A plunger body is indexed to an outer surface of the hollow body for axial movement with respect thereto. The plunger body includes a rod disposed therein for engaging the piston in the vial. An amount of medicine can be provided in the vial.

An add-on dose logging device for a pen device consumes energy when the sensors are operated and when the display is active. By using cap-off event to activate the sensor system only, and using cap-on event to de-activate the sensor system and activate the display for a given time to display a sensed dose, power consumption can be reduced without changing the user-interface and without adding any components apart from a switch.

The invention inter alia relates to a dispense interface for an ejection device. The dispense interface comprises at least two inlets, at least one outlet, a body part, and a fluid channel arrangement within the body part configured to provide fluid communication between the at least two inlets and the at least one outlet; wherein each of the at least two inlets is formed from a tubelike fluid element; wherein each of the tubelike fluid elements is molded into the body part; and wherein each of the tubelike fluid elements provides at least a part of the fluid channel arrangement within said body part.

The invention is directed to a drug delivery device (1) comprising a housing (7) retaining a primary drug delivery assembly (16) and a secondary drug delivery assembly (17). The secondary drug delivery assembly (17) comprises a secondary dose setting mechanism with a biasing member adapted to reset the secondary dose setting mechanism in a resetting movement (65). An actuator (34) is movable relative to the housing (7) and comprises a first engagement section (55) configured to engage a second engagement section (53) provided by an actuation collar (37) such that an actuation movement (63) of the actuator (34) is transferred to the actuation collar (37). A setting element (35) is movable between a first position and a second position and is connected to the secondary dose setting mechanism such that during the resetting movement (65) of the secondary dose setting mechanism, the setting element (35) is moved from the second position into the first position, wherein the setting element (35) is configured to drive the actuation collar (37) out of engagement with the actuator (34) when being moved from the second position into the first position.
