    Abstract: Provided is a cassette unit suitable for use with an auto-injector having a drive unit. The cassette unit comprises a cassette unit housing defining a cassette unit housing cavity, which is in receipt of a syringe, a rearward entrance to said cavity and a forward needle projection aperture. The cassette unit also comprises in capping relationship with the rearward entrance of the cassette unit housing, a cassette unit end-cap, said cassette unit end-cap defining a drive rod-receiving opening for receipt of a drive rod for providing forward axial drive to said plunger; a biasing element defining a biasing relationship between the cassette unit end-cap and an end flange of the syringe barrel, thereby urging the syringe forwards in relation to the cassette unit end-cap; and a damping element defining a damping relationship between the cassette unit end-cap and the flange of the syringe, thereby acting to damp rearward movement of the syringe relative to the cassette unit 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, a rearward entrance to said cavity and a forward needle projection aperture. The housing cavity may receive a syringe comprising a barrel; a needle at a front end of the barrel; and a plunger that is axially movable within the barrel. The cassette unit also comprises in capping relationship with the rearward entrance of the cassette unit housing, a cassette unit end-cap, said cassette unit end-cap defining a drive rod-receiving opening for receipt of a drive rod for providing forward axial drive to said plunger; and a biasing element defining a biasing relationship between the cassette unit end-cap and an end flange of the syringe barrel, thereby urging the syringe forwards in relation to the cassette unit end cap.

    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: 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.
