    Abstract: The present invention provides a drug delivery system (1) comprising a drug delivery device (2, 3) carrying at least one reservoir (40a, 40b), and a needle unit (4) being attachable to the drug delivery device (2, 3) in axial extension thereof and adapted to establish a flow way between the at least one reservoir (40a, 40b) and a drug delivery site. The needle unit (4) comprises a needle structure (11) comprising a front needle portion (12) for entering the drug delivery site, and at least one back needle portion (13a, 13b) for insertion into the at least one reservoir (40a, 40b), and a needle shield (20). The needle shield (20) and the needle structure (11) are capable of undergoing relative axial motion between an accommodating relative position in which the needle structure (11) is completely accommodated within the needle shield (20) and a protruding relative position in which the front needle portion (12) protrudes from the needle shield (20), the needle shield (20) and the needle structure (11) being biased towards the accommodating relative position by a first bias force. When the needle unit (4) is attached to the drug delivery device (2, 3) the needle structure (11) and the at least one reservoir (40a, 40b) are capable of undergoing relative axial motion between a disconnected relative position in which the at least one back needle portion (13a, 13b) is spaced apart from the at least one reservoir (40a, 40b), and a connected relative position in which the at least one back needle portion (13a, 13b) and the at least one reservoir (40a, 40b) are fluidly connected, the needle structure (11) and the at least one reservoir (40a, 40b) being biased towards the disconnected relative position by a second bias force which is greater than the first bias force.

    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: The invention relates to injection device, which device comprises an outer housing (1), a syringe body (10) and a needle shield (30). Both the syringe body (10) and the needle shield (30) are telescopically movable mounted to the housing (1) such that the needle shield (30) is movable relatively to the housing (1) between a first position and a second position, and the syringe body (10) is movable in relation to the housing (1) between an extended position and a retracted position.
