    摘要： 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.

    摘要： Medical device (1) for injecting a set dose of an injectable product into a patient, the device having a cartridge containing the injectable product, a movable dosing driver (11) and a movable dose setting driver (15), and an end-of-contents indicator system (13) having counting means (17) with a counting part (19), and indication means (21) with a signal part (23), wherein the counting part (19) and the signal part (23) are formed with cooperating end-of-contents contact faces (25′, 25″), wherein the signal part (23) is movable between a first indication position and a second indication position, wherein the signal part (23) comprises a biasing means (33) for biasing the signal part (23) towards the first indication position, wherein the counting part (19) comprises a coupling (26), said coupling (26) is configured for operably connecting the counting part (19) to the dose setting driver (15), such that moving of the dose setting driver(15) towards increasing the set dose moves the contact face (25′) of the counting part (19) in relation to the contact face (25″) of the signal part (23) towards engagement of the contact surfaces (25′, 25″), and such that moving of the dose setting driver (15) towards decreasing the set dose moves the contact face (25′) of the counting part (19) away from the contact face (25″) of the signal part (23), wherein the counting part (19) is configured for providing engagement of the contact faces (25′, 25″) when the set dose reach the end-of-contents in the cartridge, and wherein the counting part (19) is configured for moving the signal part (23) towards the second indication position when the set dose is exceeding the end-of-contents in the cartridge. This way, if the user tries to dial a dose of drug beyond the amount remaining in the cartridge, an additional indication is given to the user via a distinctive area (41/43) of the signal part (23) becoming visible through a window (7) of the injector.

    摘要： The present disclosure is generally directed to a resettable drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The drug delivery device comprises a housing, a cartridge holder, releasably attached to the distal end of the housing, a piston rod, engaging a housing insert and a drive member, a dose setting member, guided within the housing to allow rotation of the dose setting member during dose setting and dose dispensing, and a clutch for rotationally coupling the drive member and the dose setting member. The housing insert is rotationally constrained to the housing and is axially movable together with the drive member relative to the housing between a dose setting and dispensing position, and a resetting position. In the dose resetting position. the drive member is rotationally de-coupled from the housing.
