The drug delivery device comprises a window (5a) in the housing such that at least the symbol (7) corresponding to a selected dosage is visible. The window (5a) is recessed in the housing (1) with respect to the outer surface. The recess distance between the outer surface of the housing (1) and a surface of the window (5a) is 10 % to 70 % of the housing's (1) thickness.

Drive mechanism for a medication delivery device and medication delivery device

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.

Dose button for a drug delivery device and method for manufacturing a dose button

The present invention relates to a drug delivery device (6) comprising a dose button (1). Furthermore it relates to a method for manufacturing a dose button (1) by using a cutting-off process. The aim of the present invention is to minimize the risk of using a drug delivery device (6) containing a wrong drug. By means of tactile features, a drug delivery device (6) is distinguishable from another drug delivery device (6) containing another type of drug. This tactile feature is manufactured by using a dose button (1) out of metal which is milled or lathed.

Pen cap

The present invention refers to a pen cap (10), being capable of covering a distal end of a drug delivery device comprising at least one protruding element (16, 18, 36) located inside the pen cap (10) which prevents that the rim of an outer needle cap (14), while being a protective casing for the needle at the distal end of the drug delivery device, can get stuck within a part of the pen cap (10) if the user puts the pen cap (10) on the drug delivery device. The inner diameter of the pen cap (10) is reduced by means of the at least one protruding element (16, 18, 36), such that the inner diameter of the pen cap (10) is smaller than the largest outer diameter (26) of the outer needle cap (20). Furthermore, the invention relates to a drug delivery device comprising a pen cap (10) with the described protruding elements (16, 18, 36).

Drive mechanism for a drug delivery device

A drive mechanism for a drug delivery device which can be switched between a normal operation state and a reset state comprises: - a housing (17, 13) having a proximal end and a distal end, - a rotation member (21) which is adapted to rotate in a first direction (44) and in a second direction (47) with respect to the housing (17, 13), - a drive member (20), wherein in the normal operation state the rotation member (21) is coupled with the drive member (20) so that the drive member (20) follows rotational movement of the rotation member (21) in the second direction (47), - a piston rod (12), wherein in the normal operation state the piston rod (12) is displaced in a distal direction with respect to the housing (17, 13) when the drive member (20) rotates in the second direction (47) with respect to the housing (17, 13), - a stop member (26), wherein in the normal operation state the stop member (26) is coupled with the drive member (20) so that the stop member (26) prevents rotational movement of the drive member (20) with respect to the housing (17, 13) in the first direction, and - a separation member (70) for switching the operation state, the separation member (70) being adapted to move the stop member (26) and the drive member (20) in the distal direction with respect to the housing (17, 13) when the normal operation state is switched to the reset state, thereby decoupling the stop member (26) and the drive member (20) and decoupling the drive member (20) and the rotation member (21).

Resettable drive mechanism for a medication delivery device and medication delivery device

A resettable drive mechanism for a medication delivery device comprising a housing, a drive member rotatable with respect to the housing in a second direction for delivering a dose of a medication, and a piston rod by the drive member, when drive member rotates in the second direction, a stop member adapted to prevent rotation of drive member in a first direction, when the stop member engages the drive member, a clutch member movable between a delivery position and a reset position. When clutch member is in the delivery position, stop member and drive member are engaged and drive member is prevented from rotation in the first direction, and when the clutch member is in the reset position, the drive member and the stop member are disengaged, the drive member is rotatable in the first direction.

Resettable drive mechanism for a medication delivery device and medication delivery device

A resettable drive mechanism for a medication delivery device comprising a housing and a drive member rotatable in a second direction for delivering a dose. A piston rod driven distally when a drive member rotates in the second direction. A stop member prevents rotation of the drive member in a first direction opposite the second direction, when the stop member engages the drive member. A clutch member is movable between a delivery and reset position. When the clutch member is in the delivery position, the stop member and the drive member engage and the drive member is prevented from rotating in the first direction. When the clutch member is in the reset position, the drive member and the stop member disengage. The drive member is rotatable in the first direction.
