Sterile assembled liquid medicament dosage control and delivery device

A method of assembling a liquid medicament dispenser, comprising the steps of:

• providing a housing, a reservoir, a tubing set, an administration line, an aseptic connector assembly separated into upstream and downstream portions, and a pump;
• coupling the upstream portion of the aseptic connector assembly to the reservoir;
• filling the reservoir with a liquid medicament;
• coupling the downstream portion of the aseptic connector assembly to the tubing set;
• sterilizing together the reservoir and the upstream portion of the aseptic connector assembly;
• sterilizing together the downstream portion of the aseptic connector assembly, the tubing set, and the administration line independently from the step of sterilizing together the reservoir and the upstream portion of the aseptic connector assembly;
• providing a barrier, and interposing the barrier between the upstream and downstream portions of the aseptic connector assembly;
• connecting the upstream portion of the aseptic connector assembly to the downstream portion of the aseptic connector assembly;
• mounting the reservoir and the pump in the housing;
• providing a pull assembly coupled to the barrier, and routing the pull assembly through the housing so as to extend outside the housing;
• and
• routing the tubing set in the housing, around the pump, and through an outlet in the housing, so that the administration line extends outside of the housing.
