| 20130184652 | DRIVE MECHANISM FOR A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE - A drive member and a rotation member are rotatable with respect to a housing. A stop member is rotationally locked with the housing. Clutches unidirectionally rotationally engage the drive member with the rotation member and with the stop member when a unit is attached to the housing. A separating member is disposed between the rotation member and the stop member. The separating member causes a separation of the rotation member, the drive member and the stop member when the unit is removed. A coupling feature of the separating member is provided to engage the unit and to move the separating member when the unit is being attached to the housing or is being removed. | 07-18-2013 |

| 20130211342 | ASSEMBLY FOR A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE - An assembly for a drug delivery device is provided, comprising a housing, a rotation member adapted and arranged to be rotated in a first and in a second rotational direction with respect to the housing in an operational mode of the assembly, a drive member which is configured to mechanically cooperate with the rotation member such that the drive member follows rotation of the rotation member when the rotation member is rotated in the second rotational direction and such that the rotation member rotates with respect to the drive member when the rotation member is rotated in the first rotational direction, and a piston rod. The assembly further comprises at least one biasing member which is adapted and arranged to provide a force tending to bring the rotation member and the drive member out of mechanical cooperation in the operational mode. The assembly is switchable from the operational mode into a reset mode. For switching from the operational mode into the reset mode, the biasing member is configured to drive a relative axial movement between the drive member and the rotation member such that the rotation member and the drive member are brought out of mechanical cooperation. Furthermore, a drug delivery device is provided. | 08-15-2013 |

| 20130190719 | DRUG DELIVERY DEVICE WITH DRIVE MEMBER HAVING INDICATION ELEMENTS - A drug delivery device is proposed, which comprises a housing, a drive member which is movably retained within the housing, a piston rod which is operatively coupled to the drive member, wherein the drug delivery device is configured to convert movement of the drive member with respect to the housing into movement of the piston rod with respect to the drive member, wherein a surface of the drive member is provided with one or a plurality of indication elements, and wherein the drug delivery device is adapted to display at least one of the indication elements through the housing. Furthermore it is proposed to use a single member in a drug delivery device for driving movement of a piston rod of the device and for displaying dose related information to a user of the device. | 07-25-2013 |
| 20130204204 | DRIVE MECHANISM FOR A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE - The drive mechanism comprises a drive member inside a housing, a rotation member and a dose member. The drive member is rotatable with respect to the housing. The rotation member is also rotatable and unidirectionally rotationally engaged with the drive member. The dose member is able to move along a set/deliver path between a first axial position and a second axial position in either direction or to move along a cancel path from the second axial position to the first axial position. An engagement of the dose member with the rotation member causes the rotation member to rotate when the dose member is moved along the set/deliver path. The drive member is not rotated when the dose member is moved along the cancel path. A button in/out spline can be provided for the set/deliver path and a cancel spline for the cancel path. | 08-08-2013 |
| 20130204205 | DRIVE ASSEMBLY FOR A MEDICATION DELIVERY DEVICE AND MEDICATION DELIVERY DEVICE - A drive assembly for a medication delivery device is provided which is switchable from an operational state to a resetting state and which comprises:

| 20130211331 | DRIVE ASSEMBLY, DRIVE COMPONENT AND DRUG DELIVERY DEVICE - A drive assembly for a drug delivery device comprises a rotation member being configured to be rotated in a first direction during setting of a dose of a drug and to be rotated in a second direction during delivery of the dose, a drive component being configured to follow rotational movement of the rotation member in the second direction during delivery of the dose and a stop member being configured to prevent rotational movement of the drive component in the first direction. The drive component comprises a first drive part and a second drive part, coupled to each other such that relative rotational movement of the first and second drive parts is prevented and relative axial movement is permitted. | 08-15-2013 |
| 20130310762 | Medication Delivery Device - A medication delivery device is provided which is switchable between an operational state and a resetting state and which comprises a housing having a proximal end and a distal end, a piston rod being moveable in a distal direction with respect to the housing for medication delivery, a conversion element adapted to at least partially convert a rotational movement of the piston rod into an axial movement of the piston rod, coupling means prevented from rotational movement with respect to the housing and adapted to engage with the conversion element in the operational state, a drive assembly comprising at least two drive assembly members and adapted for moving the piston rod in the distal direction, and a resilient member adapted to provide a force on the drive assembly for engagement of the drive assembly members. In the operational state of the device the coupling means is engaged with the conversion element, the conversion element thereby being prevented from rotation with respect to the housing. In the resetting state of the device the coupling means is disengaged from the conversion element under force of the resilient member, the conversion element thereby being allowed to rotate with respect to the housing and thereby allowing a resetting of the device. | 11-21-2013 |
