Abstract: Aspects of the present invention relate to an injection device comprising a syringe carrier configured to receive a medicament container, a housing having a proximal end and a distal end; the housing being configured to receive the syringe carrier and releasably engage the proximal end of the syringe carrier and a proximal end cap arranged to engage with the proximal end of the housing and comprising a wall extending distally along the housing, the proximal end cap configured to maintain the engagement between the proximal end of the syringe carrier and the housing.

Abstract: Aspects of the present invention relate to an injection device comprising a drive means, a plunger, and an intermediate member disposed between the drive means and the plunger and releasably engaged with the plunger thereby to selectively transmit force from the drive means to the plunger.

Abstract: Aspects of the present invention relate to an injection device comprising a cartridge arranged to contain a medicament and piston and a drive mechanism arranged to move the piston from a first position where medicament is contained within the syringe and a second position in which the medicament has been delivered from the cartridge to a user. The drive mechanism includes a flexible portion which co-operates with another part of the injection device such that the flexible portion is moved towards the central axis of the injection device during a portion of the movement of the drive mechanism from the first position to the second position and disengages from the another part of the injection device at or near the second position to indicate that the medicament has been delivered from the cartridge.

Abstract: An agitator assembly for a cleaning apparatus including an agitator having a body with first and second ends, and a first alignment formation and a first securing formation at or adjacent the first end; and a drive member operable to impart rotation about a drive axis, and a second alignment formation adapted to cooperate with the first alignment formation, and a second securing formation adapted to engage the first securing formation. Relative axial movement of the agitator in a first direction towards the drive member causes contact between the first and second alignment formations. Further relative axial movement of the agitator in the first direction causes relative rotation between the agitator and drive member and yet further relative axial movement of the agitator in the first direction causes engagement between the first and second securing formations, substantially to prevent further relative rotational movement between the agitator and drive member.
