摘要： A setting mechanism for a dosing device, in particular for a device for dosing pharmaceutical or therapeutic substances, the setting mechanism including: a controlling assembly for connecting the setting mechanism with a dose setting element of the dosing device; a driving assembly for connecting the setting mechanism with a driving element of the dosing device; a dosing assembly for connecting the setting mechanism with a dosing element of the dosing device. The controlling assembly is coupled with the dosing assembly by a spring element, which can deform from a coupled position to a decoupled position during rotation of the dose setting element. The spring element is configured to allow a displacement of the controlling assembly with respect to the dosing assembly. In the coupled position the spring element is configured to block a rotation of the controlling assembly with respect to the dosing assembly.

摘要： A drive-control system for an injection device for delivering settable doses of a pharmaceutical substance contained in a cartridge (3), the system comprising a tubular housing body (2) having a longitudinal axis (A-A), a proximal end (2a) and a distal end (2b) connectable to the cartridge enclosure (3), the system further comprising a helical spring (7) contained in the housing body and a piston rod (6) moveable towards said distal end (2b) and blocked in translation towards the proximal end (2a). The housing body (2) further contains (i) a control sleeve (10) on which the spring (7) is mounted, the control sleeve (10) being rotatable around the axis (A-A), and (ii) a setting sleeve (11) translatable along the axis (A-A), wherein rotation of the control sleeve (10) in a first direction combined with compression of the spring (7) causes the setting sleeve (11) to be translated towards the proximal end (2a) of the housing body (2), and extension of the spring (7) causes the setting sleeve (11) to be translated towards the distal end (2b) of the housing body (2) and the control sleeve (10) to be rotated in a second direction and the piston rod (6) to be pushed towards the outside of the housing body (2). An injection device comprising the drive-control system according to the invention.
