Automatic injection syringe assembly with integrated, fillable medicine container and method of filling an injection syringe assembly

摘要

An automatic injection syringe assembly having an integrated and fillable medicine container that includes a medicine container within a housing and a conduit assembly. The medicine container includes a piston having an aperture at a distal end thereof for the passage of fluid therethrough. The conduit assembly includes a conduit member that is releasably connected to the housing and has an open proximal end and an open distal end. The open distal end of the conduit member is releasably engaged with the piston and in fluid communication with the piston aperture. The open proximal end and the open distal end of the conduit member are m fluid communication via a conduit within the conduit member.
