Abstract: Provided is a drive unit for an auto-injector having a drive unit housing arranged for docking receipt of a syringe or of a cassette unit comprising a syringe movable from a rest position, in which a needle tip of the syringe is within the drive unit housing to a use position, in which the needle tip protrudes from a needle delivery aperture; and a drive arrangement including one or more electrically powered sources of axial drive; a first drive transfer element for advancing the syringe to said use position; and a second drive transfer element for moving a plunger into the barrel of the syringe to eject liquid contents thereof. The drive unit housing is provided with a skin sensor arrangement having an array of plural skin sensor electrodes located about the needle delivery aperture.

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: 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.
