ABSTRACT:
An aspirator including a container having an internal chamber with the chamber having a suction tube connected to a closed bellows within the chamber for creating a vacuum, and also having a patient tube for insertion into the body cavity of a patient for sucking removal of mucus and other excess bodily fluids by the vacuum. The aspirator further includes an injection port by which mucus may be removed from the container and a pressure relief valve to permit air to escape from the container as the flexible bellows expands to its equilibrium state. The suction tube further includes a moisture trap to occlude gaseous flow to the mouthpiece in the event moisture enters the suction system. The apparatus further includes a clip to occlude fluid flow through the patient tube when the operation is completed. The patient tube may include a Yankower tip or a Murphy tip. The bellows cap may be attached to the underside of the top of the container in one of several ways.
