Abstract

A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.
