Abstract: Provided is a cassette unit suitable for use with an auto-injector having an electrically powered drive unit. The cassette unit comprises a cassette unit housing defining a housing cavity, a rearward entrance to the cavity and a forward needle projection aperture. The housing cavity may receive a syringe. Axially movable within the barrel of the syringe for forward movement into contact with the syringe plunger, there is a plunger slaving part defining a circumferential wall arranged for frictional sliding relationship with the inner wall of the barrel, a rear drive-receiving face and a front plunger-contacting face. In capping relationship with the rearward entrance of the cassette unit housing there is an end-cap defining a drive rod-receiving opening for receipt of a drive rod for providing forward axial drive to the plunger slaving part. In a pre-use configuration, the plunger slaving part is shaped for releasable engagement with the end-cap.

Abstract: Provided is a cassette unit suitable for use with an auto-injector having an electrically powered drive unit. The cassette unit comprises a cassette unit housing defining a cassette unit housing cavity and a needle projection aperture. The housing cavity may receive a syringe. Axially movable within the barrel of the syringe for forward movement into contact with the syringe plunger, there is a plunger slaving part defining a circumferential wall arranged for frictional sliding relationship with the inner wall of the barrel, a rear drive-receiving face and a front plunger-contacting face. The plunger slaving part is arranged such that when a drive load is applied to its rear drive-receiving face to bring the front plunger-contacting face into contact with the plunger the drive load is evenly transmitted. The circumferential wall is provided with slide restrictors that restrict frictional sliding movement thereof in relation to the inner wall of the barrel.

Abstract: There is provided a cassette unit suitable for use with an auto-injector. The cassette unit comprises a cassette unit housing and a removable cap that in a capping position fits over and thereby, acts to close off, a needle projection aperture of the housing. The cassette unit housing has one or more first engagement features arranged for reversibly engaging one or more second engagement features of the removable cap for reversible lock engagement of the removable cap to the housing; and a shuttle lock control defining one or more blocking elements for selectively blocking movement of said first engagement features relative to said second engagement features. The shuttle lock control is axially movable relative to the cassette unit housing between a first ‘cassette unused’ position; a second ‘cassette unlocked’ position; and after replacement of the removable cap, a third ‘cassette used’ position, locating intermediate the first and second positions.

Abstract: The autoinjector systems disclosed herein provide in part devices for allowing patients with reduced joint strength to more easily administer medicine. Certain exemplary syringe embodiments include a housing, a syringe assembly slidably mounted on the housing, and a needle cap releasably engaged to the housing, where the cap includes a protruding pocket for receiving a needle cap remover.

Abstract: Provided is a cassette unit suitable for use with an auto-injector having an electrically powered drive unit. The cassette unit has a housing defining a cassette unit housing cavity and a needle projection aperture. The housing cavity is arranged for receipt of a syringe suitable for delivery of a drug to a patient. The syringe has a barrel for containing a volume of a liquid drug formulation, the barrel defining a flange at the rear end thereof and a forward shoulder at the forward end thereof. The cassette unit includes one or more shoulder support features for supporting the forward shoulder of the syringe. In use, the one or more shoulder support features act to direct a major part of an applied load path to travel through the shoulder at the forward end of the syringe and lesser load to pass through the flange at the rear end thereof.

Abstract: Provided is an auto-injector for a syringe suitable for the injected delivery of drug to a patient. The auto-injector comprises a cassette unit arranged for receipt of a syringe. The cassette unit and/or syringe is movable from a rest position, in which the syringe needle tip is within the drive unit housing to a use position, in which the needle tip protrudes from a needle delivery aperture thereof. The auto-injector comprises a drive unit arranged for docking receipt of the cassette unit at a docking position and a drive arrangement. The drive unit is arranged for initial receipt of the cassette unit at an intermediate pre-docking position and for subsequent transport of the cassette unit to the docking position. In embodiments, the drive unit is arranged such that transport of the cassette unit to the docking position is permitted only following verification of an identifier at the intermediate pre-docking position.

Abstract: There is provided a cassette unit that is suitable for use with an auto-injector having an electrically powered drive unit. The cassette unit has a housing defining a cassette unit housing cavity and a needle projection aperture. The cassette unit housing cavity is arranged for receipt of a syringe that is suitable for use in the injected delivery of drug to a patient. The cassette unit includes a removable cap that fits over and thereby, acts such as to close off the needle projection aperture; and connecting to the removable cap, a needle cover defining a needle sheath for sheathing of the needle tip of the syringe. The removable cap is provided with a finger-grip feature that is sized and shaped for gripping by the finger of a user to allow for removal of the removable cap and needle cover from the cassette unit housing.

The cassette unit includes a removable cap that in a capping position fits over and thereby, acts such as to close off, the needle projection aperture. The cassette unit includes a cap lock feature movable from a first cap locking position in which it prevents removal of the removable cap from the capping position with the cassette unit to a second cap non-locking position in which it no longer prevents such cap removal.

Abstract: There is provided an auto-injector for a syringe that is suitable for use in the injected delivery of drug to a patient. The auto-injector comprises a cassette unit arranged for receipt of a syringe provided with a needle cover and removable cap. The auto-injector also comprises a drive unit arranged for docking receipt of the cassette unit at a docking position and a drive arrangement. The drive unit is provided with a timer that starts a time count on removal of the removable cap and needle cover from the cassette unit.
