Abstract
An aspiration flow control device includes a housing having at least one vacuum port, at least one aspiration port, and an ejection port. The at least one vacuum port is adapted to be connected to a vacuum source, and the aspiration port is adapted to be connected to an aspiration line for receiving fluids from a surgical site. The device further includes a rotating structure having at least three vanes, which structure is configured to rotate within the housing. The at least three vanes divide an enclosed volume within the housing into at least three rotating fluid collection chambers. During rotation of the rotating structure, at least one fluid collection chamber is in communication with at least one vacuum port and the aspiration port through which fluid is received, and at least one other fluid collection chamber is simultaneously in communication with the ejection port through which fluid is expelled.
