Abstract: An aspirator, a suction device for removing body fluids, is disclosed. It includes two elongated tubes: one having a tapered end for insertion into body cavities via the nose or mouth for communication with body fluids; the other elongated tube having a mouthpiece, for mouth actuation, or a squeeze-bulb, for hand actuation. The free ends of the aforementioned elongated tubes are connected to a combination isolation and liquid-collection chamber. The chamber includes an elastic impregnable barrier against the transfer of potentially infective agents between patient and user. The chamber is constructed for venting gas and vapor components from the body fluid, as well as collecting the liquid component. For mouth actuation, the user holds the mouthpiece between his or her teeth while inserting the tapered end into the body cavity from which fluid is to be extracted.
