ABSTRACT:
An aspirator device for removing body fluids is disclosed as having a fluid collector with an air-type chamber that communicates with a first sealed passageway in an elongated flexible tube to be inserted in a body cavity for fluid communication with body fluids, and a second sealed passageway which connects the air tight chamber with a manually operable vacuum device or squeeze bulb. The manually operable vacuum means or squeeze bulb is operatively associated with first and second one-way valve which open in the same direction, the first valve establishing a vacuum in the first and second sealed passageways for remvoing and depositing harmful body fluids in the fluid collector, and the second valve means not only working to establish the vacuum, but also serving as an overflow valve for fluids overflowing the fluid collector. The manually operable vacuum device or squeeze bulb is also supported in a relatively stable and rigid position relative to the fluid collector to facilitate one-handed gripping and operation thereof by a user.
