Claim 0:
1. A connector for a fluid drainage system, comprising:
a body defining a drainage lumen extending along a longitudinal axis from a distal portion to a proximal portion;
a piston housing providing fluid communication between the distal portion and the proximal portion;
an inlet configured to provide fluid communication between a source of pressurized air and the piston housing;
a pneumatic lumen extending external to the piston housing and providing fluid communication between the inlet and the proximal portion of the drainage lumen, a central axis of the pneumatic lumen extending at an angle of between 20° and 70° relative to the longitudinal axis of the drainage lumen; and
a piston slidably engaged with the piston housing along a transverse axis between a first position and a second position, wherein:
the piston in the first position provides fluid communication between the distal portion and the proximal portion of the drainage lumen, and occludes an inlet end of the pneumatic lumen to occlude fluid communication between the inlet and the proximal portion of the drainage lumen; and
the piston in the second position occludes fluid communication between the distal portion and the proximal portion of the drainage lumen, and opens the inlet end of the pneumatic lumen to provide fluid communication between the inlet and the proximal portion of the drainage lumen.
