  • Patent number: 8529503
    Abstract: The present invention relates to a medicament delivery device comprising a generally elongated housing comprising a proximal part (10) and a distal part (12); a medicament cartridge (18) comprising a proximal opening closed by a septum (30), an axially movable distal stopper (26), and a first enclosure (20) wherein a liquid and a gaseous fluid are enclosed; a medicament delivery member (36) attachable to said proximal part (10) and having a non-delivery end (34); a medicament cartridge holder (16) wherein the medicament cartridge is coaxially arranged, said cartridge holder being arranged coaxially movable inside said proximal part and comprising holding means (38, 40) capable of holding said medicament cartridge holder (16) in a non-activated position in which said cartridge holder is releasebly engaged to said proximal part and in which a predetermined distance is present between the septum and the non delivery end; a manual pressure mechanism arranged to be moved from a non-pressure position to a pressure

  • Publication number: 20130218074
    Abstract: A medicament delivery device includes a housing; a drive force mechanism slidable in the housing's distal part; a member connected to the drive force mechanism for holding it in a loaded state and axially movable in relation to the distal part a predetermined distance by the housing's proximal part when the parts are moved toward each other; and an actuation member to be biased in relation to the distal part from a non-operating position partially protruding from the distal part to an operating position confined within the distal part. The actuation member can release the drive force mechanism from its loaded state, and is resiliently connected to the distal part such that it is always recoiled after being biased regardless of whether the actuation mechanism is released. The drive force mechanism is released only after the holding member moves and the actuation member is biased from non-operating to operating position.

  • Patent number: 8372031
    Abstract: The present invention relates to an injection device for manually penetrating a needle arranged to said device and automatic injecting a medicament mixture, the device being of the type comprising: a first housing part into which a multi-chamber container is arranged and a second housing part which can be displaced relative to said first housing in order to mix at least two substances arranged inside said container; a plunger rod arranged to act on said container, drive force means capable of pushing said plunger rod for acting on said container, an activation member comprising flexible locking means releasibly connected to said plunger rod for holding said plunger rod and thereby said drive force means in a pre-tensioned state, and a push button protruding from said second housing part; and a locking member being arranged around said activation member and being axially slidable in relation to said activation member between a first position wherein said locking member completely surrounds said locking means a

  • Publication number: 20120150125
    Abstract: The present invention relates to a safety pen needle device comprising a first needle shield (60) and a second back-end needle shield (90). During the injection the first needle shield (60) is moved to en retracted position this movement causes a actuation sleeve (31) to rotate. Said rotation causes a holding member (96, 98) provided on the second needle shield (90) to be released. When the first needle shield (60) is moved from the retracted position to a extended position the actuation sleeve (31) is rotated further so that a first guide member (74) on the first needle shield (60) abuts a first stop member (34) arranged on said actuation sleeve (31). After an performed injection both shields are moved to extended positions by the rotation of an actuation sleeve (31). After the injection the shield are locked it their extended position.
