An injection device includes a housing having a longitudinal axis extending. A dose setting member is rotatable in the housing in a first or second direction about the longitudinal axis. A plunger extends through a bore of the dose setting member and into a bore of a barrel engaged with the housing. Pushing on an arm extending through a slot in the housing rotates the dose setting member in the first direction. As it rotates, indicia on the dose setting member are progressively displayed through an aperture in the housing. An actuator is engaged to release the dose setting member to rotate in the second direction and this rotation causes the plunger to move axially within the barrel's bore and push the pre-set dose of fluid therefrom. The dose setting member remains in a constant axial position within the housing during rotation in each of the first and second directions.

A supplemental device configured for attachment to an injection device, the supplemental device comprising: a camera configured to generate camera output indicative of a scene viewable by the camera, and to be located on an optical path with a surface of an injection device attached to the supplemental device in use; a light source having an emission spectrum and configured to illuminate the surface with light within the emission spectrum in use; and a filter configured to be located on the optical path between the camera and the surface in use, the filter being substantially opaque to light across the entire emission spectrum of the light source and substantially transparent to light of at least one frequency outside the emission spectrum of the light source.

The present invention refers to a drug delivery device comprising a housing (5, 10) with an opening (12), a piston rod (11) having a proximal end and a distal end, at least a portion with an interface (14) adapted to engage the opening (12) for guiding the piston rod (11) during a distal or proximal movement of the piston rod (11) relative to the housing (5, 10) and at least one first attachment element (15) located at the distal end, and a bearing (16) with at least one second attachment element (17, 18) for rotatable attachment of the bearing (16) at the distal end of the piston rod (11). The at least one first attachment element (15) and/or the at least one second attachment element (17, 18) is elastically deformable in a radial direction for snap engagement of the piston rod (11) and the bearing (5, 10). The opening (12) comprises at least one portion having a contour adapted to receive the at least one first attachment element (15) and the at least one second attachment element (17, 18) if attached to each other but preventing disengagement of the at least one first attachment element (15) and the at least one second attachment element (17, 18) if received in the opening (12). Further, the present invention refers to an assembly method for a drug delivery device.

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.

An injection apparatus (2) comprising a housing (4) and an injector sub-assembly (6), wherein the injector sub-assembly is located within the housing; the injector sub-assembly includes a needle (20), a syringe barrel (18) and a piston (40) located within the syringe barrel; the injector sub-assembly is slidably mounted within the housing between an operative configuration in which at least a portion of the needle projects from the housing, and a retracted configuration in which the injector sub assembly is wholly located within the housing; and wherein the housing includes a housing body and needle exit door (44) pivotally connected to the body such that the door closes a needle exit aperture defined by the housing body when the injector sub-assembly is in its retracted configuration and opens when the injector sub-assembly is in its operative configuration to permit the needle to exit the housing.

According to an embodiment, a cartridge driving module comprises a motor and a shaft extending along a rotational axis of the motor, a power transmission screwed to the shaft and moving forward when the shaft rotates in a forward direction and moving back when the shaft rotates in a backward direction, a pusher connected to the power transmission and exerting a pressure to a medicine cartridge containing a medicine when the power transmission moves forward, and a position maintaining unit exerting an external force to the power transmission in a direction along which the power transmission moves forward, when the power transmission moves back up to a predetermined stop position.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose-cartridge and permit a user to set the delivery dose. The injector may include a housing, a piston rod adapted to operate through the housing, a dose dial sleeve located between the housing and the piston rod, and a drive sleeve located between the dose dial sleeve and the piston rod. The dose dial sleeve may have a helical thread of first lead and the drive sleeve may have a helical groove of second lead. The first lead of the helical thread and the second lead of the helical groove may be the same.

Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

An assembly (47) for a medication delivery device (1) has a body (2), a dose setting part (8) configured to be operated by a user for selecting a size of a dose, a piston rod (13) configured to be moved axially without rotating for dispensing a medication, and a drive member (12) being directly coupled to the piston rod (13) for driving the piston rod (13) in a dose dispensing operation, wherein the drive member (12) moves in a proximal direction in a dose setting operation. The medication delivery device (1) into which the assembly is incorporated may be a single-shot, variable-dose injection device, e.g., a syringe.
