Sterile assembled liquid medicament dosage control and delivery device

1. 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.

2. The method of claim 1 , wherein the aseptic connector assembly further comprises:

a first bore in the upstream portion of the aseptic connector assembly and a first seat around the first bore;

a second bore in the downstream portion of the aseptic connector assembly and a second seat around the second bore;

first and second gaskets, each seated in the respective first and second seats of the respective upstream and downstream portions of the aseptic connector assembly; and

the step of interposing further comprises disposing the barrier between the first and second gaskets.

3. The method of claim 2 , wherein the step of connecting the upstream portion of the aseptic connector assembly to the downstream portion of the aseptic connector assembly further comprises:

aligning the first and second bores, and the first and second gaskets, of the upstream and downstream portions, respectively, with each other; and

applying the upstream portion of the aseptic connector assembly to the downstream portion of the aseptic connector assembly with the first and second gaskets disposed therebetween, forming a sterile passageway through the aseptic connector assembly from the reservoir to the tubing set.

4. The method of claim 1 , wherein the barrier is irreversibly removable from the aseptic connector assembly.

5. The method of claim 1 , further comprising:

providing a switch assembly for energizing the dispenser in a closed state of the switch assembly; and

operatively coupling the switch assembly to the barrier so that removal of the barrier from the aseptic connector assembly places the switch assembly in the closed state thereof.

6. The method of claim 1 , further comprising the steps of:

providing a printed circuit board carrying a pressure sensitive resistor; and

routing the tubing set against the pressure sensitive resistor.
