  • Publication number: 20140213983
    Abstract: According to the invention, a safety device suitable (S) for a pre-filled syringe containing a medicament comprises a chassis adapted to be affixed to the pre-filled syringe, a deformable flexible outer structure made from a material with a shape memory and a substantially cylindrical needle shield affixed or integral to the outer structure. The deformed flexible outer structure is capable of advancing the needle shield with respect to the chassis in a distal direction (D) into a position in which the needle shield projects from the chassis in the distal direction (D). A biasing force for advancing the needle shield originates from a shape memory effect that causes the deformed flexible outer structure to substantially return to its unstressed shape.

  • Publication number: 20130331794
    Abstract: According to the invention, a safety device for a pre-filled syringe comprises a hollow support body to retain the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a guide pin, a guide track and a cut-out adjacent to the guide track. The guide pin protrudes into the guide track and moves within and along the guide track when the needle shield is slid relative to the support body. The cut-out allows a side wall of the guide track to be deflected in a lateral direction perpendicular to a central axis of the safety device.

  • Publication number: 20130184652
    Abstract: A drive member and a rotation member are rotatable with respect to a housing. A stop member is rotationally locked with the housing. Clutches unidirectionally rotationally engage the drive member with the rotation member and with the stop member when a unit is attached to the housing. A separating member is disposed between the rotation member and the stop member. The separating member causes a separation of the rotation member, the drive member and the stop member when the unit is removed. A coupling feature of the separating member is provided to engage the unit and to move the separating member when the unit is being attached to the housing or is being removed.
