    Abstract: A delay mechanism for staging the operation of an automatic injection apparatus to ensure medication contents are properly delivered prior to the needled syringe of the apparatus being retracted. In one form, the delay mechanism includes a shuttle, a follower, a locking member, a damping compound, and a driver and a driver biasing element. The shuttle is for a needled syringe of the apparatus and includes a first latching element. The follower includes a second latching element and a cammable surface, which second latching element is for cooperating with the first latching element to limit motion of the shuttle relative to the follower in a second direction opposite the first direction. The locking member is movable from a locking position to a release position by engagement with the syringe plunger during an injection, the locking member, when in the locking position, preventing rotation of the follower relative to the shuttle, the locking member, when in the release position, allowing rotation of the follower relative to the shuttle. The damping compound is between the follower and a supporting surface to dampen rotation of the follower relative to the shuttle. The driver is rotatably fixed relative to the shuttle and includes a camming surface. The driver biasing element is for forcing the driver from a first position to a second position when the locking member moves to the release position, whereby during movement of the driver to the second position, the driver camming surface engages the follower cammable surface to force the follower to rotate relative to the shuttle from a latching position, at which the first and second latching elements cooperate, to an unlatching position, at which the second latching element is disengaged from the first latching element to allow movement of the shuttle for retracting the syringe needle into the housing of the automatic injection apparatus after injection.

    Abstract: A medical device (10) is provided which includes a shield system (14) and a syringe (12) which is coupled to the shield system. The shield system includes a syringe holder (26) and a shield (28) which is slidably coupled to the holder. A spring (30) resiliently urges the shield from a retracted position to an extended position. Stop members (48, 52) are provided on the holder and shield for maintaining the shield in the retracted position. The syringe is slidably coupled to the holder, and extends within the shield. Axial movement of the syringe with respect to the holder causes disengagement of the stop members, allowing the spring to move the shield to the extended position. Detends (58, 59) are provided on the holder for maintaining the shield in the extended position.

    Abstract: The present invention relates to a dial-up/dial-down mechanism for an injection device by which a dose can be set by rotating a dose setting member in a first direction and which dose size can be reduced by rotating the same dose setting member in a second and opposite direction. The dial-up/dial-down mechanism operates a torsion spring which is strained when setting a dose and unstrained when rotating the dose setting element in the second direction. In order to secure the torsion spring when strained, a ratchet arm (21) following the rotation of the dose setting element in the first direction, engages a toothed element (10) such that engagement of the at least one ratchet arm (21) with teeth (12) of the toothed element (10) prevents unwinding of the torsion spring, and wherein the rotation of the dose setting member in the first direction moves the ratchet arm (21) from one tooth (12) to the subsequent tooth (12) of the toothed element (10), and rotation of the dose setting member in the second direction lowering the set dose activates the ratchet arm (21) to disengage the teeth (12) of the toothed element (10) and thereby allow the torsion spring to move the ratchet arm (21) in the second direction to the previous tooth (12) such that the force accumulated in the torsion spring reduces incrementally. In order to provide a smooth movement when dialling down the set dose, the at least one ratchet arm (21) is associated with friction means (16, 30) dampening the movement of the ratchet arm (21) by the torsion spring.
