Abstract: The invention relates to a torsion spring driven injection device for delivering individually set doses of a liquid drug wherein a torsion spring is strained by rotation of a rotatable dose setting element and released by axial movement of a clutch which couples the dose setting element with the drive tube and the drive tube with a piston rod guide driving the piston rod. When straining the torsion spring the clutch is decoupled from a piston rod guide such that the piston rod guide is able to rotate independently and coupled to the dose setting element. During dose expelling the clutch is moved into engagement with the piston rod guide and out of engagement with the dose setting element such that the piston rod guide rotates with the clutch under influence of the torsion spring. The invention further relates to a non-axial movable End-of-Content mechanism preventing the user from setting a dose larger than the content of the injectable liquid drug remaining in the cartridge of the injection device.

Abstract: The present invention relates to an injection device for automatic torsion spring driven injection of a liquid drug. The injection device is of the type wherein a telescopically movable needle shield activates the release of the torque of the torsion spring to drive the injection when the needle shield is moved from its extended position to a retracted position. The injection device further has a needle holder carrying the injection needle, which needle holder is axially movable both in relation to the housing and in relation to the needle shield. It is therefore possible to retract the needle shield in relation to the housing and at the same time move the needle holder to its extended position such that the injection needle is presented outside the needle shield thereby providing for easy exchange of the injection needle.

Abstract: The present invention relates to a torsion spring driven injection device for delivering multiple set doses of a liquid drug from a cartridge by moving a plunger forward inside the cartridge. The torsion spring (134) applies a rotational torque onto a drive member (120) engaging a piston rod (115) which is then driven forward by this rotation. The piston rod driver can be coupled and de-coupled from the torsion spring mechanism. In the de-coupled position, the piston rod driver is freely rotatable and can thus rotate if the piston rod is moved axially. A further torsion arrangement (124) is preferably provided such that a torque is build up between the piston rod driver and the housing whenever the piston rod is moved backwards. This torsion arrangement urges the piston rod driver to rotate in a direction bringing the piston rod forward into abutment with the plunger.

Abstract: A device for administering a fluid medicament by injection comprises a dosing portion (1) with a collapsible reservoir (10). The reservoir (10) has a maximum volume in an extended state and a minimum volume in a collapsed state. Prior to injection, the reservoir (10) is in the extended state and contains a liquid to be administered, and the reservoir (10) is biased towards the collapsed state. The device further comprises a needle (2), wherein a lumen (20) of the needle (2) is in fluid communication with the reservoir (10). The device further comprises a shield portion (3) with a plug (30). Prior to injection, the shield portion (3) is in a deployed position where the plug (30) blocks the lumen (20) of the needle (2). The shield portion (3) is adapted to move in response to an actuation force from the deployed position to a retracted position where the lumen (20) of the needle (2) is open, thereby causing the reservoir (10) to shift to the collapsed state to expel the liquid through the needle.

Abstract: The present invention relates to a torsion spring based automatic injection device for apportioning set doses of a liquid drug and which injection device is provided with an End-of-Dose feedback mechanism providing a user with an audible signal once the set dose has been injected. During injection, the scale drum rotates back to its “zero” position under influence of the torsion spring. This rotation is halted shortly before reaching the “zero” position by stopping means. The scale drum is thereafter only allowed to continue rotation and thus reach the “zero” position once the torque applied to the scale drum by the torsion spring surpasses a threshold value.
