A liquid medicament dispenser includes a housing and a pump carried by the housing, a reservoir applied to the housing and containing a pre-filled sterile liquid medicament, a sterile tubing set routed through the pump, a sterile administration line carried outside of the housing and coupled aseptically to the sterile tubing set in fluid communication, and an aseptic connector coupled to the reservoir and the sterile tubing set and changeable from a storage state to a use state. In the storage state, the aseptic connector prevents the liquid medicament in the reservoir from moving to the sterile tubing set. In the use state of the aseptic connector, the aseptic connector defines a sterile passageway for the flow of the liquid medicament from the reservoir to the sterile tubing set.
