Context-sensitive flow interrupter and drainage outflow optimization system

An apparatus for optimizing outflow in drainage assemblies, the apparatus comprising:

• a mechanical template to shape a tube, the mechanical template providing a monotonic downward gradient for fluid passing through a drainage tube from a body cavity or space to a drainage collection receptacle for the drainage tube shaped with the mechanical template.

A drainage assembly comprising:

• a drainage tube having at least two vents in an interior wall of the drainage tube.

The drainage assembly according to claim 18, wherein the context-sensitive flow interrupter comprises:

• an actuator portion on a section of a drainage path of the drainage tube, the actuator portion comprising a flow interrupter that inhibits fluid from passing through the drainage path at the section of the drainage tube having the actuator portion, wherein interacting the actuator portion with a holder portion changes the state of the flow interrupter of the actuator portion.

A drainage system, comprising:

• a drainage tubing;
• and
• a bypass channel for a desired vacuum or pressure to circumvent an obstruction caused by accumulated liquid in an undrained liquid-filled dependent loop in the drainage tubing.
