摘要:
A drive assembly (70) for a drug delivery device (1) comprises a rotation member (21) being configured to be rotated in a first direction (44) during setting of a dose of a drug and to be rotated in a second direction (47) during delivery of the dose, a drive component (20) being configured to follow rotational movement of the rotation member (21) in the second direction (47) during delivery of the dose and a stop member (26) being configured to prevent rotational movement of the drive component (20) in the first direction (44). The drive component (20) comprises a first drive part (71) and a second drive part (72), coupled to each other such that relative rotational movement of the first and second drive parts (71, 72) is prevented and relative axial movement is permitted.
摘要:
A piston rod (9) for a drug delivery device (1) comprises a main body (14) and an engagement means (12) for engaging the piston rod (9) with a part (11) of the drug delivery device (1). The engagement means(12) are retractable relatively the main body (14) for enabling a disengagement of the engagement means (12) from the part (11) of the drug delivery device (1).
摘要:
A semi-automatic "fixed" dose injection device (1) is disclosed containing a reservoir of medicament, where a trigger (6) controls the unwinding of a torsional spring (18) to cause a predetermined injection of medicament from the reservoir through a disposable needle.
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 single-use cartridge for a medication delivery device, comprises a body element (1) having a proximal end and a distal end, a dispensing means (5), and a deformable capsule (3) containing medication. The capsule (3) is disposed inside the body element (1) and has a skin which encases the medication. The capsule (3) is configured to be pushed in the distal direction against the dispensing means (4) so that the content of the capsule (3) is dispensed.
摘要:
An injection device (1) for administering a fixed dose of a medication is provided. The injection device (1) comprises a housing (2) wherein a drive mechanism comprising a drive member (3) is at least partially enclosed and a dosing element (34) which is fixed relative to the drive member (3). Here, a dose can be set by rotating the dosing element (34) relative to the housing (2) in a dose setting direction (s) and the dose can be dispensed by pushing the dosing element (34) towards the housing (2). A dose can be set by rotating a dosing element (34), a dose can be dispensed by pushing the dosing element (34) towards the housing (2) and a dose can be cancelled by rotating the dosing element (34) in a direction opposite to the dose setting direction(s).
