11. The device of claim 10 wherein the cover of the liner-type medical suction apparatus includes a first boss extending upwardly from the second port and a second boss extending downwardly from the first port, and wherein the conduit is coupleable to the first boss and the pre-attached tube is coupled to the second boss.

12. A device for draining a liner-type medical suction apparatus, the liner-type medical suction apparatus including a liner, a liner interior filled with fluid, and a cover, the device comprising:

a drainage device housing;

a cradle in the drainage device housing, the cradle being adapted to support the cover of the liner-type medical suction apparatus when the liner-type medical suction apparatus is in an inverted position; and

a breakout pipe including a first end coupled to the cradle and a second end for communication with the liner interior, the breakout pipe being movable upwardly between a storage position in which the second end is stored substantially within the cradle and a drainage position in which the second end is in communication with the liner interior through the cover.

14. The device of claim 12 wherein the cover includes a flap valve, and wherein the breakout pipe moves the flap valve between a closed position when the breakout pipe is in the storage position and an open position when the breakout pipe is in the drainage position.

15. The device of claim 12 wherein the cover includes a frangible portion, and wherein the breakout pipe is adapted to break the frangible portion when the breakout pipe is moved upwardly into the drainage position.
