Compounder apparatus

A containment assembly for enclosing a medication vial, the containment assembly comprising:

• an interface portion having a proximal end and a distal end, the interface portion including a housing wall which defines a channel spanning from the proximal end to the distal end, the channel open at the proximal end and the distal end;
• at least one pierceable septum disposed at least at one of:
• on the proximal end of the channel, and
• within the channel forming a barrier between the proximal end of the channel and the distal end of the channel;
• a variable-volume housing portion having a variable volume chamber, the variable-volume chamber of the variable-volume housing portion being in fluid communication with the distal end of the channel, wherein the distal end of the interface portion includes a mating feature which mates with a cooperating mating feature of the variable-volume housing portion;
• and
• a gasket member configured to compress between the interface portion and the variable-volume housing portion when the interface portion is mated to the variable-volume housing portion.

• and
• a variable-volume housing portion having a variable volume chamber, the variable-volume chamber of the variable-volume housing portion being in fluid communication with the distal end of the channel, wherein the at least one pierceable septum includes at least two pierceable septa disposed within the channel, a first septum of the at least two pierceable septa disposed proximal the proximal end, a second septum of the at least two pierceable septa disposed distal to the proximal end relative to the first septum.

A containment assembly for enclosing a medication vial, the containment assembly comprising:

• an interface portion having a proximal end and a distal end, the interface portion including a housing wall which defines a channel spanning from the proximal end to the distal end, the channel open at the proximal end and the distal end;
• a plurality of elastomeric septa disposed within the channel forming a barrier between the proximal end of the channel and the distal end of the channel;
• and
• a variable-volume housing portion, at least a portion of the variable-volume housing portion being a variable volume formed of an elastomeric material.
