Abstract

A medical apparatus for draining bodily fluid from a container, such as a suction canister. The medical apparatus can include a support area and a drainage reservoir having an inlet in communication with the support area and an outlet in communication with a drain. The drainage reservoir can collect the bodily fluid from the container before the bodily fluid flows into the drain. Some embodiments of the medical apparatus include a drainage conduit or a drainage pipe. In some embodiments, the drainage reservoir is constructed of a transparent material. The medical apparatus can include a venturi valve and, in some embodiments, the water passing through the venturi valve remains separate from the bodily fluid until the water and the bodily fluid reach the drain.
