摘要：
The present invention concerns an injection device (110) with a housing (112)adapted to receive a syringe (114) having a discharge nozzle (118), thehousing having an indicator opening (113). There is a trigger (111) and aforward drive (132) arranged to act upon the syringe on actuation of thetrigger to advance the syringe form a retracted position to an extendedposition thereby discharging the contents of the syringe through the dischargenozzle. A support member (122) is in contacting juxtaposition with the housingand a return drive (126) is supported by the support member and arranged toact upon the syringe after the contents of the syringe has been discharged sothat the syringe can be withdrawn from the extended position to the retractedposition. Advantageously, the support member is arranged in the housing sothat the second drive does not obscure an inspection of the contents of thesyringe through the indicator opening. Hence, it can be clearly determinedwhether the contents of the syringe have been expelled from the syringe.
