Sterile assembled liquid medicament dosage control and delivery device
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.
1. A liquid medicament dispenser comprising:
a housing and a pump carried by the housing;
a medicament reservoir carried in the housing and containing a 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;
an aseptic connector assembly comprising a first portion in which a first annular gasket is received, an opposed second portion in which a second annular gasket is received, and a barrier disposed in contact between the first and second annular gaskets, wherein the first portion is engaged with the reservoir, the second portion is fit to the tubing set, and the barrier is removable from between the annular gaskets to change the aseptic connector assembly from a storage state to a use state;
in the storage state of the aseptic connector assembly, the reservoir is carried in the housing, the first portion of the aseptic connector assembly is engaged with the reservoir, the second portion of the aseptic connector assembly is fit to the tubing set, the first and second portions of the aseptic connector assembly are coupled to each other and compressed together, thereby compressing the first and second annular gaskets against each other with the barrier therebetween, and the barrier occludes the aseptic connector assembly to prevent the liquid medicament in the reservoir from moving to the sterile tubing set; and
in the use state of the aseptic connector assembly, the first portion of the aseptic connector assembly is engaged with the reservoir, the second portion of the aseptic connector assembly is fit to the tubing set, the first and second portions of the aseptic connector assembly are coupled and compressed together, thereby compressing the first and second annular gaskets against each other, and the barrier is removed from the aseptic connector assembly, thereby bringing the first and second annular gaskets into direct and sealing contact with each other, coupling the reservoir and the tubing set in fluid communication, and defining a sterile passageway for the flow of the liquid medicament from the reservoir to the sterile tubing set;
wherein, as the aseptic connector assembly is moved from the storage state to the use state, the first and second portions of the aseptic connector assembly remain coupled to each other and are maintained in coaxial alignment with each other.

the first and second portions of the aseptic connector assembly are each formed with a bore and a seat around the respective bore;
the first and second annular gaskets are each seated in the seat of the respective first and second portions; and
the barrier is disposed between the first and second annular gaskets of the first and second portions of the aseptic connector assembly, respectively.
9. The liquid medicament dispenser of claim 8 , wherein, in the use state of the aseptic connector assembly, the first portion of the aseptic connector assembly is engaged in an irreversible engagement with the second portion of the aseptic connector assembly, coupling the reservoir to the sterile tubing set in fluid communication.
10. The liquid medicament dispenser of claim 1 , wherein the barrier extends from the aseptic connector assembly to outside of the housing.
11. The liquid medicament dispenser of claim 1 , wherein the barrier includes:
a first thin film bonded to the first portion of the aseptic connector assembly; and
a second thin film bonded to the second portion of the aseptic connector assembly.
12. The liquid medicament dispenser of claim 11 , wherein the first thin film is secured to the second thin film outside of the housing.
13. The liquid medicament dispenser of claim 1 , wherein the pump is a peristaltic pump.
