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. The user then seals his or her lips about the mouthpiece and alternately decreases and increases the volume of his or her mouth cavity as many times as required to extract the fluid sought. During hand operation, the user grips a squeeze-bulb in one hand and squeezes and releases same as many times as necessary to remove the sought after liquid.
An aspirator device for removing body fluids comprising an air-tight chamber for receiving body fluids, first and second elongated tubes having first and second sealed passageways communicating with said air-tight chamber and a one-way exit tube operably associated with said air-tight chamber, the first elongated tube having a free end adapted to be inserted into a body cavity for fluid communication with body fluids, the second elongated tube having a free end to which an air source is operably connected, an inflatable/deflatable elastic barrier operably associated with said second elongated tube in order to allow said air source to first inflate and thereby expand the elastic barrier and force an equal volume of air through said one-way exit tube and from said air-tight chamber, said elastic barrier also being contracted when said air source deflates to open a one-way valve associated with said first elongated tube, in order to draw body fluid through the first sealed passageway of the first elongated tube for deposit of liquid content in the air-tight chamber of the liquid collector and subsequent ejection of gas and vapor content when said elastic barrier is again inflated, and said one-way exit tube extending a predetermined distance within said air-tight chamber to an open upper end to enable a predetermined amount of liquid to be collected within said air-tight chamber below the open upper end of said one-way exit tube, while permitting gas and vapor and any excess liquid to be exhausted through the one-way exit tube.
In an aspirator device for removing body fluids including a fluid collector having an air-tight chamber for receiving body fluids, first and second elongated tubes having first and second sealed passageways communicating with said air-tight chamber, said first elongated tube having a free end adapted to be inserted in a body cavity for fluid communication with body fluids, said second elongated tube having a free end for connection to an air source to establish a partial vacuum in said passageways to remove fluids from said body for deposit of liquid content in said fluid collector, the improvement comprising an elastic barrier to separate said first and second sealed passageways from each other while allowing differential air pressure from the air source to inflate and deflate and thereby expand or contract the elastic barrier for ejecting gas, vapor and excess liquid from or drawing body fluid into said air-tight chamber, and a one-way exit tube for exhausting an equal volume of air filling said air-tight chamber on one side of said elastic barrier during expansion thereof, said one-way exit tube being closed during contraction of said elastic barrier to establish a vacuum within said second sealed passageway for removing fluids from the body cavity for deposit in said fluid collector, said one-way exit tube extending for a predetermined distance within said air-tight chamber and terminating in an open upper end to enable a predetermined amount of liquid to be collected within said air-tight chamber below said open upper end, while permitting any excess liquid to be exhausted through the one-way exit tube.
