An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

Assembly for a drug delivery device and drug delivery device

An assembly for a drug delivery device () is proposed, comprising a housing () having a proximal end and a distal end, a dose member () which is displaceable in the proximal direction with respect to the housing for setting of a dose of a drug, a clutch member () which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member () configured to define a clutch stop position for the proximal displacement of the clutch member with respect to the housing, with the clutch member, when in the clutch stop position, being prevented from further displacement in the proximal direction with respect to the housing, wherein the clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose. Furthermore, a drug delivery device () is proposed.

An assembly for a drug delivery device (), and a drug delivery device, are proposed with a housing () having proximal and distal ends. A dose member () is displaceable proximally with respect to the housing for setting of a dose of a drug. A clutch member () is displaceable proximally with respect to the housing when setting the dose. A stop member () is configured to define a clutch stop position for the proximal displacement of the clutch member with respect to the housing, The clutch member, when in the clutch stop position, is prevented from further displacement proximally with respect to the housing, and the clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member proximally with respect to the housing during setting of the dose.

A method of preventing setting a dose which exceeds an amount of medication contained in a medication receptacle of a medication delivery device. The device comprising a piston rod comprising a second stop element, a drive device for moving the piston rod, and a dose setting member for setting a dose. The method comprising the steps of moving a dose limiting member which comprises a first stop element axially with respect to the piston rod during dose setting, and utilizing the first and second stop elements to stop an axial movement of the dose limiting member in the proximal direction when the first and second stop elements catch, limiting a movement of the dose setting member for increasing a set dose of medication. The dose limiting member and the piston rod only interact directly, when the first and second stop elements catch.

Medication delivery device

The present invention relates to a medication delivery device, to dosing mechanisms suitable for use in such medication delivery device, in particular in pen-type injectors, preferably having a dose setting member and a drive device enabling the dose setting and the administration of a medicinal product from a multi-dose medication cartridge, to methods using such device, and to methods of manufacturing and assembly of such device.
