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 use in the injected delivery of drug to a patient. The syringe has a barrel for containing a volume of a liquid drug formulation, the barrel defining an end flange at the rear end thereof and a forward shoulder at the forward end thereof. The cassette unit includes a sleeve form adapter arranged for receipt by the syringe barrel and to fit at least partly over the end flange of the syringe barrel. Accommodation of different syringe sizes within the same cassette unit geometry is achievable by selecting a sleeve form adapter tailored to the particular sizing of the barrel of each different syringe.
