Fluid evacuation collection vessel assemblies and fluid evacuation systems and methods

A collection vessel assembly for receiving a fluid, the collection vessel assembly comprising:

• a collection vessel;
• a vacuum source valve in fluid communication with the collection vessel;
• a drain valve in fluid communication with the collection vessel;
• an interconnection between the vacuum source valve and the drain valve configured to operate the vacuum source valve and the drain valve in a plurality of interconnected states;
• and
• wherein the interconnection is a mechanical interconnect comprising:
• a vacuum source valve extension attached to the vacuum source valve;
• a drain valve extension attached to the drain valve;
• a vertical extension attached to the vacuum source valve extension and the drain valve extension;
• a handle portion;
• and
• wherein the handle portion is configured to operate the interconnect in each of the plurality of interconnected states.

A collection vessel assembly for receiving a fluid, the collection vessel assembly comprising:

• a vacuum source valve in fluid communication with the collection vessel;
• a drain valve in fluid communication with the collection vessel;
• an interconnection between the vacuum source valve and the drain valve configured to operate the vacuum source valve and the drain valve in a plurality of interconnected states;
• wherein manipulation of the interconnection to a fluid extraction state exposes the collection vessel to vacuum pressure while placing the vacuum source valve in an open position and the drain valve in a closed position, and wherein manipulation of the interconnection to a drain state exposes the collection vessel to atmosphere while placing the drain valve in an open position to permit drainage of any fluid in the collection vessel through the drain valve;
• and
• where when the interconnection is manipulated from the fluid extraction state to the drain state the vacuum source valve is closed to vacuum and the collection vessel is exposed to the atmosphere prior to the drain valve opening to the open position.
