摘要:
The invention relates to a dose setting mechanism (1) for a drug delivery device (2), comprising a number of separate dose setting elements (3.1 to 3.n), wherein a dose volume and/or a dose number are/is set by moving at least one of the respective dose setting elements (3.1 to 3.n) from a stack position (I) to an initial position (II), and wherein a medicament dose volume is applied by moving at least one dose setting element (3.1 to 3.n) from the initial position (II) to a dispense position (III) and wherein the movement of the dose setting element (3.1 to 3.n) from the initial position (II) to the dispense position (III) is limited by at least a height (h) of the dose setting elements (3.1 to 3.n) in the initial position (II), wherein each dose setting element (3.1 to 3.n) comprises a plurality of bulges (B1 to Bm) on at least one surface side (S1), wherein the height (h) of each dose setting element (3.1 to 3.n) equals a sum of the thickness (D) of the dose setting element (3.1 to 3.n) and the bulge height (h1).

摘要:
A safety device suitable for a pre-filled syringe containing a medicament includes 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 into a position in which the needle shield projects from the chassis in the distal direction. 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.

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.
摘要:
Described is a device for intraocular injection comprising a drug delivery device, a foot at a distal end of the drug delivery device for positioning the drug delivery device with respect to an injection site, and a magnifying device coupled to one of the drug delivery device and the foot for magnifying a view of the injection site.
摘要:
A resettable drug delivery device is provided comprising a body, a cartridge holder for receiving a cartridge, and means for releasably coupling the cartridge holder to the body or the dose setting mechanism. During an initial rotational coupling movement of the cartridge holder relative to the body or the dose setting mechanism the cartridge holder is caused to move in a first axial direction relative to the body or the dose setting mechanism and during a continued rotational coupling movement of the cartridge holder relative to the body or the dose setting mechanism the cartridge holder is caused to move in a second, contrary axial direction.
摘要:
A dose setting mechanism for a drug delivery device is provided comprising first maximum dose stop features (1) on a first component part (2) of the drug delivery device and corresponding second maximum dose stop features (3) on a second component part (4) of the drug delivery device, with the first and second maximum dose stop features (1, 3) being designed to limit a relative movement between the first and second component parts (2, 4). To limit the maximum dose which can be chosen, a maximum dose limiting device (5, 10, 10′, 10″, 10″′) is provided interposed on the first component part (2) between the first and second maximum dose stop features (1, 3).
摘要:
A semi-automatic injection device (12) is disclosed containing two reservoirs (6) of medicament, where a trigger (11) controls the unwinding of two torsional springs (18) to cause simultaneous injection of medicament from each reservoir through a needle adaptor configured with a 2 to 1 needle cannula arrangement.

A drive mechanism for a drug delivery device which can be switched between a normal operation state and a reset state comprises of a housing having a proximal end and a distal end, a rotation member which is adapted to rotate in a first direction and in a second direction with respect to the housing, a drive member, wherein in the normal operation state the rotation member is coupled with the drive member so that the drive member follows rotational movement of the rotation member in the second direction, a piston rod, wherein in the normal operation state the piston rod is displaced in a distal direction with respect to the housing when the drive member rotates in the second direction with respect to the housing, a stop member, wherein in the normal operation state the stop member is coupled with the drive member so that the stop member prevents rotational movement of the drive member with respect to the housing in the first direction, and a separation member for switching the operation state, the separation member being adapted to move the stop member and the drive member in the distal direction with respect to the housing when the normal operation state is switched to the reset state, thereby decoupling the stop member and the drive member and decoupling the drive member and the rotation member.
摘要:
A turbomachine includes a compressor portion having an intake and a filtration system having an interior and an exterior. The filtration system is arranged upstream of the intake and includes a drain capable of fluid communication with the exterior of the filtration system. The drain includes a one-way valve that allows liquid separated from air flowing through the interior of the filtration system to pass through the drain to the exterior of the filtration system in a first direction, and substantially limits a flow of unfiltered air from entering the intake from the exterior in a second direction.
