INJECTION DEVICE WITH SYRINGE CARRIER ENGAGEMENT WITH CAP

摘要

An injection device (110) is described having a housing (112) that receives a syringe (114) having a needle (118), wherein the syringe is supported in a syringe carrier (150). The injection device (110) has a removable cap (190). The syringe (114) and syringe carrier (150) are biased by a return spring (126) from an extended position in which the needle (118) extends from the housing (112) through an exit aperture (128) to a retracted position in which it does not. The syringe carrier (150) abuts a surface inside the removable cap (190) which prevents forward movement of the syringe carrier (150) when the cap is in place. The injection device is less prone to failure than prior art devices and is safer should failure occur.
