Abstract

A partially-implantable pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A tube of the pneumostoma management device is placed through the chest wall into the lung. The tube comprises a plurality of holes in the distal end to allow the entry of gases and non-gaseous discharge from the lung. A contact surface prevents over-insertion of the tube while releasably securing the device to the chest of the patient. The contact surface has features to reduce irritation of the skin of the chest.

Claims

1. A pneumostoma management device adapted to be mounted on a chest of a patient to treat a lung of a patient and control flow of liquids and gases through a pneumostoma wherein the pneumostoma management device comprises:

a tube adapted to pass into the pneumostoma wherein the tube has at least one opening in a distal end of the tube and at least one side opening adjacent the distal end of the tube adapted to be positioned within the lung to allow liquids and gases to enter the tube from the lung;

a bulb connected to a proximal end of the tube wherein the bulb defines a chamber;

an external opening in the bulb;

a hydrophobic filter positioned in the external opening which allows gases to escape the chamber via the external opening and which prevents liquids from escaping the chamber via the external opening;

whereby gases may pass from the lung of the patient through the pneumostoma management device and escape through the external aperture and whereby liquids may pass from the lung into the chamber where they are trapped by the hydrophobic filter.

2. The pneumostoma management device of claim 1, wherein the tube has a distal opening and at least two side openings adapted to be positioned within the lung to allow liquids and gases to enter the tube from the lung.

3. The pneumostoma management device of claim 1, wherein the bulb comprises a flange substantially perpendicular to the tube and adapted to contact the chest of the patient surrounding the pneumostoma to prevent over-insertion of the tube.

4. The pneumostoma management device of claim 3, wherein the flange comprises a plurality of discreet patches of adhesive positioned to secure the flange to the chest of the patient.

5. The pneumostoma management device of claim 3, wherein the flange has a plurality of raised regions adapted to contact the chest of the patient while spacing one or more non-raised regions of the flange away from the chest and being thereby adapted to inhibit accumulation of moisture between the flange and the chest of the patient.

6. The pneumostoma management device of claim 1, wherein the bulb comprises a flange substantially perpendicular to the tube and adapted to releasably secure the pneumostoma management device to the chest.

7. The pneumostoma management device of claim 1, wherein the bulb comprises a flange substantially perpendicular to the tube and adapted to releasably secure the pneumostoma management device to the chest while permitting air to circulate between the flange and the chest.

8. The pneumostoma management device of claim 1, wherein the bulb is formed in one piece with the tube.

9. The pneumostoma management device of claim 1, wherein the hydrophobic filter is press-fit into the external opening of the bulb.

21. The pneumostoma management device of claim 1 including at least one side opening adjacent the opening in the distal end of the tube.

10. A medical device to control movement of gases and non-gaseous discharge through a pneumostoma wherein the medical device comprises:

a tube adapted to pass into the pneumostoma wherein the tube has a plurality of openings in a distal end of the tube adapted to be positioned within the lung to allow gases and non-gaseous discharge to enter the tube from the lung;

a bulb connected to a proximal end of the tube wherein the bulb defines a chamber adapted to contain non-gaseous discharge;

an external opening in the bulb;

a filter positioned in the external opening which allows gases to escape the chamber via the external opening, and which prevents non-gaseous discharge from escaping the chamber via the external opening;

whereby gases may escape from the lung through the medical device and non-gaseous discharge is trapped by the filter.

11. The medical device of claim 10, wherein at least one of the plurality of openings is located through a wall of the tube adjacent the distal end of the tube.

12. The pneumostoma management device of claim 10, wherein the bulb comprises a flange substantially perpendicular to the tube and adapted to contact the chest of the patient surrounding the pneumostoma to prevent over-insertion of the tube.

13. The pneumostoma management device of claim 12, wherein the flange comprises a plurality of discreet patches of adhesive positioned to secure the flange to the chest of the patient.

14. The pneumostoma management device of claim 12, wherein the flange has a plurality of raised regions for contacting the chest of the patient while spacing one or more non-raised regions of the flange away from the chest and being thereby adapted to inhibit accumulation of moisture between the flange and the chest of the patient.

15. The pneumostoma management device of claim 10, wherein the bulb comprises a contact surface substantially perpendicular to the tube and adapted to releasably secure the pneumostoma management device to the chest.

16. The pneumostoma management device of claim 10, wherein the bulb comprises a limit surface substantially perpendicular to the tube and adapted to releasably secure the pneumostoma management device to the chest while permitting air to circulate between the flange and the chest.

17. A medical device which controls movement of gases and non-gaseous discharge through a pneumostoma wherein the medical device comprises:

a tube formed in one piece with a bulb wherein the bulb comprises a contact surface substantially larger in diameter than the tube and such that the tube is adapted to be pushed into the pneumostoma until the contact surface contacts a chest of a patient;

wherein the tube has a plurality of openings proximate to a distal end of the tube adapted to be positioned within the lung to allow gases and non-gaseous discharge to enter the tube from the lung;

an external opening in the bulb;

a filter positioned in the external opening which allows gases to escape the bulb via the external opening and which prevents non-gaseous discharge from escaping the bulb via the external opening;

whereby the medical device controls movement of gases and non-gaseous discharge through the pneumostoma.

18. The medical device of claim 17, wherein at least one of the plurality of openings is located through a wall of the tube adjacent the distal end of the tube.

19. The pneumostoma management device of claim 17, wherein the contact surface is adapted to releasably secure the pneumostoma management device to the chest while permitting air to circulate between the flange and the chest.

20. The pneumostoma management device of claim 17, wherein the contact surface comprises a plurality of raised regions for contacting the chest of the patient while spacing one or more non-raised regions of the contact surface away from the chest and being thereby adapted to inhibit accumulation of moisture between the contact surface and the chest of the patient.

22. The medical device of claim 17 wherein the tube extends substantially perpendicular to the contact surface.
