Abstract

An apparatus includes a disposable assembly and a reusable assembly. The disposable assembly includes a fluid input port, a fluid output port, and a tube configured to provide fluid communication between the fluid input port and the fluid output port. The reusable assembly includes a housing, a fluid management assembly that is configured to transition between an open position and a closed position, and a sensing assembly. The fluid management assembly is configured to prevent fluid from traveling past the tube to the fluid output port in the closed position. The sensing assembly is configured to sense fluid accumulating within the tube while the fluid management assembly is in the closed position. The sensing assembly is also configured to drive the fluid management assembly from the closed position to the open position when the sensing assembly detects fluid within the tube at a predetermined range.
