Abstract

An aspirator device for removing body fluids is disclosed as having a fluid collector with an air-tight 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 removing 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. A method of mechanically removing body fluids from a body is also disclosed.

Claims

1. An aspirator device for removing body fluids comprising a fluid collector having an air-tight chamber for receiving body fluids, an elongated flexible tube connected to said collector and including a first sealed passageway communicating with said air-tight chamber, said elongated flexible tube having a free end adapted to be inserted into a body cavity for fluid communication with body fluids, a squeeze bulb connected to said collector and associated with a second sealed passageway communicating with the air-tight chamber of said collector, said squeeze bulb being operatively associated with first and second one-way valve means which open in the same direction, said first one-way valve means being operatively connected relative to said second sealed passageway to permit air to be withdrawn in one direction through the first sealed passageway, air-tight chamber and second sealed passageway upon compression and release of said squeeze bulb for establishing a vacuum through said passageways to remove body fluids for deposit in said collector, and said second one-way valve means being operatively connected to said squeeze bulb to allow air to be expelled therethrough to atmosphere as well as permit fluids overflowing the collector to be drawn through the first one-way valve means for discharge through said second one-way valve means and removal of overflowing fluids from said squeeze bulb, said squeeze bulb being operatively associated relative to the other components of said aspirator device to facilitate one-handed gripping, lifting and operation of the aspirator device by the squeeze bulb.

2. The aspirator device as defined in claim 1 wherein said squeeze bulb is structurally supported relative to the other components of said aspirator device to facilitate one-handed gripping, lifting and operation of the aspirator device by the squeeze bulb.

3. The aspirator device as defined in claim 2 wherein said squeeze bulb is supported in relatively stable position in close proximity to said collector by means associated with and mounted to said collector.

4. The aspirator device as defined in claim 3 wherein the squeeze bulb when lifted also mounts and supports the collector thereto through a relatively rigid and stable connection between the squeeze bulb and said collector.

5. The aspirator device as defined in claim 1 wherein said first and second valve means comprise normally closed valve means mounted in the wall of said squeeze bulb which open and close in response to compression and expansion of said squeeze bulb.

6. The aspirator device as defined in claim 1 wherein said first and second valve means are positioned in tandem relationship in a self-contained valve enclosure mounted upon and in fluid communication with said fluid collector, said squeeze bulb also being connected to and in fluid communication with said self-contained valve enclosure.

7. The aspirator device as defined in claim 6 wherein said first and second valve means comprise normally closed valve means which open and close in response to squeezing and expansion of said squeeze bulb.

8. The aspirator device as defined in claim 5 or 7 wherein each said normally closed valve means has a flapper valve body with a fluid opening therethrough which communicates with said aforesaid passageways when the normally closed valve means is opened.

9. The aspirator device as defined in claim 5 or 7 wherein each said normally closed valve means comprises a flexible disk means which is distorted to expose fluid communicating openings when the normally closed valve means is opened.

10. An aspirator device for removing body fluids comprising a fluid collector having an air-tight chamber for receiving body fluids, an elongated flexible tube connected to said collector and including a first sealed passageway communicating with said air-tight chamber, said elongated flexible tube having a free end adapted to be inserted into a body cavity for fluid communication with body fluids, a squeeze-bulb connected to said collector and associated with a second sealed passageway communicating with the air-tight chamber of said collector, said squeeze-bulb operatively associated with first and second one-way valve means which open in the same direction, said first one-way valve means being operatively connected relative to said squeeze bulb and second sealed passageway to permit air to be withdrawn in one direction through the first sealed passageway, air-tight chamber and second sealed passageway upon compression of the squeeze-bulb for establishing a vacuum therethrough to remove body fluids for deposit in said collector, and said second one-way valve means being operatively connected to the squeeze-bulb in order to allow air to be withdrawn therethrough as well as permit fluids overflowing the collector to be drawn past the first one-way valve means, said squeeze bulb being supported in a substantially stable and rigid position in relatively close proximity to said collector such that upon lifting the squeeze bulb, the collector is also thereby lifted for one-handed operation of the squeeze bulb while supporting its associated collector.

11. The aspirator device as defined in claim 10 and including a second tube containing said second sealed passageway connected between said collector and said squeeze-bulb.

12. The aspirator device as defined in claim 11 wherein said squeeze-bulb is supported through a relatively rigid and stable second tube and said collector in close proximity to squeeze bulb.

13. The aspirator device as defined in claim 12 wherein said second tube comprises a reversely bent tube section which extends first upwardly from the collector and then downwardly alongside said collector for positioning said squeeze-bulb in close proximity.

14. The aspirator device as defined in claim 13 wherein said reversely bent tube section includes at least one relatively rigid elbow section for supporting said squeeze-bulb in a relatively stable position in close proximity to said collector.

15. The aspirator device as defined in claim 13 wherein said reversely bent tube section includes at least one relatively flexible elbow section for supporting said squeeze-bulb in close proximity to said collector.
