摘要:
A drive mechanism for a medication delivery device (1) is proposed, the drive mechanism comprising a housing (13, 17, 40) having a proximal end and a distal end, a rotation member (21) which is adapted to be rotated in a first direction with respect to the housing during setting of a dose of a medication and to be rotated in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction, a piston rod (12) which is adapted to be displaced in a distal direction with respect to the housing for delivering the dose, a drive member (20) which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member (26) which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose, wherein the rotational movement of the drive member in the second direction is converted into movement of the piston rod in the distal direction with respect to the housing. Furthermore, a medication delivery device is provided for.
摘要:
A drive assembly for a drug delivery device (100), comprising a housing (10) with a proximal end (11) and a distal end (12), and a longitudinal axis (A) extending between the proximal end (11) and the distal end (12), a rotation sleeve (40) being rotatable relative to the housing (10), and a piston rod (50) being axially moveable relative to the housing (10). The piston rod (50) is in mechanical cooperation with the rotation sleeve (40) to be rotatable and moveable in the distal direction relative to the housing (10) when the rotation sleeve (40) rotates in a first direction (D1) and to be stationary in axial direction relative to the housing (10) when the rotation sleeve (40) rotates in a second direction (D2) opposite to the first direction (D1).
摘要:
A cartridge holder (2), which has a distal end and a proximal end, comprises a coupling housing portion (14) in which a cartridge can be inserted at least partly. The coupling housing portion (14) is configured to be coupled to a part of a drug delivery device. The cartridge holder (2) further comprises a fixing member (21) which is connected with the coupling housing portion (14). The fixing member (21) is moveable radially inwardly to a position in which the fixing member (21) is suitable for securing the cartridge against distal displacement of the cartridge.
