Abstract: A device (1) for delivering an injectable drug to a patient for example from a conventional syringe (37) with a hypodermic needle. The device (1) provides to a user an audible, visible and/or tactile end of dose indication after all of the medicament has been delivered. The end of dose indication can be provided by releasing energy stored within an energy storage means (3d), energy having been imparted to the energy storage means (39) during the delivery of the injectable drug. The energy storage means (3d) acts upon an end of dose indicator (41) which interacts with another part of the device (1), for example an external housing (3), to produce the end of dose indication.

Abstract: An injection device includes a housing for receiving a syringe or cartridge for containing a medicament; a rotary driveshaft mounted for rotation relative to the housing; and an elongate coiled torsion spring having respective formations at opposite ends thereof, with a first formation being anchored in a seat on the rotary drive shaft and a second formation being anchored in a seat on a reaction component. In use relative rotation of the rotary driveshaft and the reaction component in one angular direction strains the torsion drive spring, and release of the strained torsion drive spring causes expression of medicament from the syringe or cartridge. The torsion spring is longitudinally resiliently compressible between its end formations whereby during assembly of the injection device, the torsion spring may be longitudinally compressed and then rotated, thereby urging the end formations of the torsion drive spring into engagement with the respective seats.
