Abstract

A system for draining the chest cavity of a patient subjected to a traumatic chest injury and/or to surgery within the chest. The system includes a small, portable suction device and a chest tube with an improved terminal structure. A number of embodiments of the suction device are disclosed; the first (with two variations) a small, completely disposable, bottle-shaped assembly comprising a motor/pump section, a power section, and a desiccant filled chamber, the second (also with two variations) a small box shaped assembly with a disposable desiccant pouch and a power supply that mounts to a battery charger positioned on an IV pole. A number of chest tube terminus structures are disclosed, including multi-lumen structures having high-airflow and low-airflow lumens as well as “dead” and “live” lumens. Fenestrations are variously positioned between and through the lumens in order to collect coagulated components of the extracted fluids and prevent them from clogging the primary flow tube and restricting or preventing continuous airflow.

Claims (46)

1. A suction device comprising:

a pump operatively connected to a power supply;

a desiccant material in a desiccant chamber fluidly connected to the pump;

a tube fluidly connected to the desiccant chamber through a tube connection;

a terminus having a first lumen and a second lumen fluidly connected to the tube on an end opposite the tube connection, the first lumen and the second lumen sharing a same wall; and

a plurality of fenestrations positioned through the first lumen and the second lumen to allow air and liquid to flow between the first lumen and the second lumen;

wherein the first lumen is larger than the second lumen to permit a higher flow rate in the first lumen than in the second lumen.

2. The suction device of claim 1 , wherein said desiccant chamber contains anti-microbial and/or anti-bacterial chemicals able to render suctioned air and liquids non-bio-hazardous.

3. The suction device of claim 1 , wherein said desiccant chamber is constructed of clear, high impact plastic.

4. The suction device of claim 1 , wherein said desiccant chamber is removably attachable to said pump.

5. The suction device of claim 1 , wherein said tube connection allows said tube to be removably connectable to said desiccant chamber.

6. The suction device of claim 5 , wherein said tube connection is a screw-on or quick connect fitting.

7. The suction device of claim 1 , further comprising a trocar attached to the tube on the end opposite the tube connection.

8. The suction device of claim 1 , wherein said pump creates suction through said tube.

9. The suction device of claim 8 , wherein said first lumen and said second lumen are in direct communication with said pump.

10. The suction device of claim 8 , wherein said first lumen is in direct communication with said pump, and said second lumen is in indirect communication with said pump.

11. The suction device of claim 8 , wherein said first lumen comprises inflexible walls, and said second lumen comprises flexible walls.

12. The suction device of claim 8 , wherein said suction in said first lumen is greater than said suction in said second lumen.

13. The suction device of claim 12 , wherein said tube further comprises a plurality of low-flow lumens, each connected to said pump and each of said plurality of low-flow lumens capable of having an individual suction level.

14. The suction device of claim 1 , wherein said terminus comprises a central suction tube and a dead space in an interior of said terminus, wherein said central suction tube has fenestrations between said central suction tube and said dead space that allow communication between said central suction tube and said dead space.

15. The suction device of claim 1 , wherein said tube further comprises one or more sensors.

16. The suction device of claim 15 , wherein said one or more sensors are chosen from flow rate, pressure, oxygen saturation, electrocardiogram, and respiratory rate sensors.

17. The suction device of claim 15 , wherein said one or more sensors are remotely monitorable.

18. A suction device comprising:

a pump operatively connected to a power supply;

a desiccant material in a desiccant chamber fluidly connected to the pump;

a tube fluidly connected to the desiccant chamber through a tube connection; and

a terminus having a first lumen and a second lumen fluidly connected to the tube on an end opposite the tube connection, the first lumen and the second lumen sharing a same wall;

wherein said first and second lumens comprise a central suction tube and a dead space in an interior of said terminus, wherein said central suction tube has fenestrations between said central suction tube and said dead space that allow communication between said central suction tube and said dead space.

19. The suction device of claim 18 , wherein said desiccant chamber contains anti-microbial and/or anti-bacterial chemicals able to render suctioned air and liquids non-bio-hazardous.

20. The suction device of claim 18 , wherein said desiccant chamber is constructed of clear, high impact plastic.

21. The suction device of claim 18 , wherein said desiccant chamber is removably attachable to said pump.

22. The suction device of claim 18 , wherein said tube connection allows said tube to be removably connectable to said desiccant chamber.

23. The suction device of claim 22 , wherein said tube connection is a screw-on or quick connect fitting.

24. The suction device of claim 18 , further comprising a trocar attached to the tube on the end opposite the tube connection.

25. The suction device of claim 18 , wherein said pump creates suction through said tube.

26. The suction device of claim 25 , wherein said first lumen and said second lumen are in direct communication with said pump.

27. The suction device of claim 25 , wherein said first lumen is in direct communication with said pump, and said second lumen is in indirect communication with said pump.

28. The suction device of claim 25 , wherein said first lumen comprises relatively inflexible walls, and said second lumen comprises relatively flexible walls.

29. The suction device of claim 25 , wherein said suction in said first lumen is greater than said suction in said second lumen.

30. The suction device of claim 29 , wherein said tube further comprises a plurality of low-flow lumens, each connected to said pump and each of said plurality of low-flow lumens capable of having an individual suction level.

31. The suction device of claim 18 , wherein said tube further comprises one or more sensors.

32. The suction device of claim 31 , wherein said one or more sensors are chosen from flow rate, pressure, oxygen saturation, electrocardiogram, and respiratory rate sensors.

33. The suction device of claim 31 , wherein said one or more sensors are remotely monitorable.

34. The suction device of claim 18 , wherein the terminus has a plurality of lumens, and wherein the plurality of lumens includes the first lumen and the second lumen.

35. The suction device of claim 1 , wherein the terminus has a plurality of lumens, and wherein the plurality of lumens includes the first lumen and the second lumen.
