Abstract: A prefilled syringe may be interfaced with and used to fill an infusion pump with therapeutic liquid. The dispensing end of the prefilled syringe may be coupled (either directly or indirectly using a syringe cap) to a syringe coupling region of the infusion pump, for example, using a threaded engagement or snap fit engagement. As the dispensing end of the prefilled syringe is coupled to the syringe coupling region of the pump housing, a needle passes through the pump housing and/or a needle passage region of the dispensing end such that the prefilled syringe is fluidly coupled to a reservoir in the pump. In various embodiments, the needle may be located in the syringe coupling region or in a syringe cap coupled to the dispensing end of the prefilled syringe.
