A data collection device comprises: a first portion having one or more features configured for attaching of the first portion to a dosage knob of an injection device; a second portion rotatably coupled with the first portion, wherein at least part of the second portion is movable axially relative to the first portion; a sensor arrangement configured to detect rotation of the first portion relative to the second portion; and a processor arrangement configured to, based on said detected movement, determine a medicament amount expelled by the injection device, wherein the coupling arrangement is configured to provide a non-permanent coupling between the first portion and the dosage knob of the injection device.

A medication injection pen, including a housing, a dose set knob (DSK) comprising an internal key, and a dose stop member engaging the dose set knob. Rotation of the dose set knob to set a medication dose causes rotation of the dose stop member with respect to the dose set knob, and when the dose set knob is rotated to a last dose setting position, the dose stop member rotationally abuts the internal key thereby preventing further rotational movement of the dose set knob in a dose setting direction.

A drive mechanism for a drug delivery device having a rotationally fixed plunger rod driven by a lead screw. The lead screw engages a free lock which is coupled to a release knob. A dose setting dial cooperates with an inner cylinder using a clutch to establish the axial movement of the plunger rod during dose setting and dispensing.

A data collection device for attachment to an injection device and for collecting medicament dosage information therefrom.

A syringe fixture for holding a syringe in a test system, the fixture comprising a main housing comprising a first chamber, a second chamber, and an opening extending from the first chamber to the second chamber, wherein the first chamber comprises a first plurality of walls and a second plurality of walls forming a housing for at least a needle of the syringe, wherein the second chamber is configured to hold at least a flange portion of the syringe and the second chamber comprises a cover to enclose at least the flange portion of the syringe; and a base portion having a support, wherein the base portion is configured to receive a portion of a plunger rod, and wherein the base portion includes at least one geometric feature configured to allow or impart a rotational motion on the portion of the plunger rod received in the base portion.

A dosing device for an injection device, the dosing device including an actuating element for adjusting and/or dispensing a dose from the injection device, a thrust element for generating a forward movement for discharging a dose and a coupling to which the actuating element and the thrust element are coupled such that a rotational movement of the actuating element is transmitted directly to the thrust element and an axial movement of the actuating element is different than an axial movement of the thrust element.

The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament and to an insert for such a device. The insert comprises a cup-shaped body with a distal end and a proximal end. The body has a sidewall and a tube which extends centrally through the cup-shaped body in a longitudinal direction, thereby defining an annular space between the sidewall and the tube. The annular space is open in the proximal direction for receiving a compression spring. The tube comprises a thread provided at an inner surface of the tube. Further, the tube, the sidewall and/or a second part comprise a clutch feature for rotationally constraining a component part to the insert.

A fluid delivery device has a syringe barrel-type reservoir with plunger and plunger driver assembly comprising nested, telescopic screws comprising an innermost screw keyed to a first side of the plunger or intermediate pusher to prevent rotation. In a fully retracted position, the nested screws do not extend into the reservoir. The nested screws all have right handed threads and employ the same pitch in their respective inner thread and outer thread designs. The outermost screw is connected to a motor for controllable rotation. The decreasing torque ratios from the outermost to innermost screw member and anti-rotation feature allows the innermost screw to advance the plunger into the reservoir before the adjacent concentric screw member commences rotating and advancing within its corresponding screw, and so on, to translate the plunger and expel fluid in a fluid chamber defined on the other, second side of the plunger.

The present disclosure concerns an indication mechanism for an automatic applicator, particularly for insulin or other liquid preparations, particularly for multiple injection administration of set doses of a medicine from an exchangeable container, for example for the self-application of insulin by diabetes patients. An indication mechanism for an automatic applicator, having an assembly of at least two barrels movably coupled to each other has an indication barrel mounted on the driving barrel contains only marking on its external surface and is co-axially connected to the pull-push control nut.

A system for injecting medium into a patient includes an automated injector including a reservoir, an ejector for ejecting a volume of fluid medium from the reservoir, and an actuator coupled to the ejector. An input device includes a syringe housing, a plunger, a circuit board coupled to a first component of the input device, a plunger position sensor, a battery, and a transmitter for sending an input device action signal to the automated injector. The input device action signal is based at least in part on a signal sent from plunger position sensor. A diversion apparatus is disposed downstream from the reservoir and is configured to receive at least a first portion of the volume of the fluid medium ejected from the reservoir.
