A rotary sensor assembly comprises an indicator member adapted to rotate and having first and second axial positions, input means adapted to be actuated by movement of the indicator member, and a processor adapted to receive input from the input means. The indicator member comprises a plurality of actuator structures, and the input means comprises one or more switches adapted to be actuated by an actuator structure. Zero or more switches is/are actuated when the indicator member is moved from the first to the second axial position, this corresponding to a first switch pattern, and zero or more switches is/are actuated when the indicator member is moved from the second to the second axial position, this corresponding to a second switch pattern. Based on input from one or more switches corresponding to the first and second switch patterns, the processor is adapted to determine rotational movement of the indicator member.

摘要:
The present invention relates to a drug delivery device for dispensing of a liquid medicament, the device comprising: - a housing (20; 120) to accommodate a cartridge (40) filled with the medicament and having a piston (44) slidably displaced inside the cartridge (40) and sealing a proximal end (42) of the cartridge (40), - at least one resilient member (60; 160) having a first end (61; 161) arranged at an inside facing side wall portion (26) of the housing (20; 120) and having a second end (62; 162) opposite to the first end (61; 161) to abut with the piston (44) of the cartridge (40).
摘要:
A cartridge holder assembly is provided, comprising an enclosed cartridge, a distal portion and a proximal portion. The enclosed cartridge defines a longitudinal axis and comprises a generally cylindrical main portion, a distal outlet portion having a neck portion with a circumferential shoulder portion, and a proximal portion having an opening surrounded by a circumferential rim. The distal portion comprises a distal support structure engaging the cartridge neck portion and being adapted to support the cartridge against movement in the distal direction, and the proximal portion comprises a proximal support structure engaging the cartridge circumferential rim and being adapted to support the cartridge against movement in the proximal direction. The proximal support structure is essentially non-deformed, and the distal support structure engaging the cartridge neck portion is plastically deformed.
