Abstract

Devices and methods are disclosed for achieving chest drainage in humans or other animals. Chest drainage is often required following traumatic injury or surgery. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting. The devices utilize a chest tube with a cutting distal end and a central blunt trocar. The blunt trocar or obturator shields the sharp cutting distal end of the chest tube until controllably retracted. Once the blunt trocar or obturator is retracted, the chest tube is advanced out through its sterile, protective package and into the patient. The blunt trocar is advanced back into its position to shield the sharp tip of the chest tube during patient insertion. The chest tube also includes a hold-down mechanism that is created by an adhesive seal to the patient'"'"'s chest and ribbons or straps that are wrapped around the chest tube once it is correctly positioned. The straps include adhesive ends to grip the chest tube once the straps are in place.

Claims

1. An apparatus adapted for chest drainage comprising:

a tube characterized by a proximal end, a distal segment adapted fro insertion into the chest and a lumen communicating from the proximal end to the distal end;

a plurality of perforations at the distal end of said tube communicating between the lumen and the outside of the tube;

a connector at the proximal end of said tube for connecting the through lumen of said tube to drainage apparatus;

a cutter located at the distal end of said tube;

an obturator or blunt tip capable of selectively protecting the sharp edge of said cutter; and

means for longitudinally translating the obturator relative to the cutter such that the obturator may be selectively advanced to a position distal to the cutter.

2. The apparatus of claim 1 wherein said obturator is retractable into the lumen of said tube.

3. The apparatus of claim 1 wherein said obturator is removable from the lumen of said tube.

4. The apparatus of claim 1 wherein said obturator or blunt tip is automatically advanced following penetration of the chest.

5. The apparatus of claim 1 wherein said tube is packaged inside a sterile barrier that may be pierced with said cutter.

6. The apparatus of claim 1 wherein said obturator is operably connected to a handle located near the proximal end of said tube.

7. The apparatus of claim 1 wherein said tube further comprises a malleable element disposed along at least a part of the length of said tube.

8. The apparatus of claim 1 wherein said tube further comprises a flange to limit penetration depth of the tube when the tube is inserted into an incision.

9. A method of achieving chest drainage at an incision site on a patient, said method comprising the steps of:

providing a protective patch having one or more straps extending therefrom, adhering a protective disc with its center over the incision site;

making an incision or a hole partially through the thickness of the chest wall at the incision site;

thereafter bluntly dissecting through the remainder of the thickness of the chest wall at the incision site;

providing a chest tube that is sealed within a sterile barrier package, said chest tube characterized by a proximal end, a distal segment adapted for insertion into the chest, and a lumen communicating from the proximal end to the distal segment;

puncturing a sterile package containing said chest tube;

advancing said chest tube out of said packaging;

inserting said chest tube into the prepared incision in the patient'"'"'s chest;

attaching said chest tube to straps attached to the protective disc to hold the chest tube in place; and

enabling drainage of liquid through the chest tube from the patient'"'"'s chest cavity.

10. The method of claim 9 wherein the drainage is enabled by expanding a volume operably connected to the proximal end of the lumen of the chest tube so as to generate a vacuum within the lumen.

11. The method of claim 9 wherein the initial incision in the chest wall is made with a punch.

12. The method of claim 9 wherein the drainage is enabled by allowing a spring to expand a volume operably connected to the proximal end of the lumen of the chest tube.

13. An apparatus adapted for chest drainage comprising:

an axially elongate tube further comprising a proximal end, a distal end and a through lumen;

a plurality of perforations at the distal end of said tube communicating between the through lumen and the outside of the tube;

a connector at the proximal end of said tube for connecting the through lumen of said tube to drainage apparatus;

a flange affixed to the tube, wherein the flange limits the depth of penetration of the tube within a patient; and

a removable obturator or blunt tip, coaxially mounted to the distal end of said tube, wherein said removable obturator or blunt tip is able to bluntly dissect tissue.

14. The apparatus of claim 13 wherein said flange is configured to stop at the outside surface of the skin.

15. The apparatus of claim 13 wherein said flange is configured to stop at the outside aspect of the ribs.

16. The apparatus of claim 13 further comprising a deflector, wherein said deflector is capable of diverting a secondary catheter laterally, when said secondary catheter is passed through said apparatus.

17. The apparatus of claim 16 further comprising a seal between the apparatus and the secondary catheter.

18. The apparatus of claim 13 wherein said apparatus is short, rigid and blunt, and wherein said apparatus cannot be inserted into a patient'"'"'s chest wall so as to cause damage to internal organs.

19. The apparatus of claim 13 further comprising a patch, wherein the adhesive patch can be affixed to the patient'"'"'s chest wall around the apparatus.

20. The apparatus of claim 13 wherein the obturator or blunt tip is not removable.
