Abstract

Claims (33)

1 . A drainage system for draining a fluid from a patient, the drainage system comprising:

a catheter;

a collection container;

a drainage tube configured to provide fluid communication between the catheter and the collection container, wherein the drainage tube includes a port and a balloon attached to an interior of the drainage tube by surrounding a membrane disposed on an interior side of the port, wherein an interior cavity of the balloon is configured to:

receive a gas from a needle that has pierced the port, the needle entering the interior cavity of the balloon, and

occlude a lumen of the drainage tube; and

an output airflow device coupled to the collection container configured to draw airflow out of the drainage tube.

2 . The system of claim 1 , wherein, when in an inflated state, the balloon occludes the lumen of the drainage tube thereby breaking the fluid communication between the catheter and the collection container and preventing the output airflow device from drawing airflow out of the catheter.

3 . The system of claim 1 , wherein the membrane is a self-sealing membrane.

4 . The system of claim 1 , wherein the port is located at a distal end of the drainage tube.

5 . The system of claim 1 , further comprising a hydrophobic filter coupled in line with the drainage tube between the collection container and the output airflow device.

6 . A drainage tube for use within a drainage system for draining a fluid from a patient, the drainage system including a catheter, a collection container and an output airflow device coupled to the collection container, the drainage tube comprising:

a tubing having a lumen extending from a proximal end to a distal end;

a port; and

a balloon attached to an interior of the drainage tube by surrounding a membrane disposed on an interior side of the port, wherein an interior cavity of the balloon is configured to:

receive a gas from a needle that has pierced the port, the needle entering the interior cavity of the balloon, and

occlude a lumen of the drainage tube.

7 . The drainage tube of claim 6 , wherein the drainage tube is configured to provide fluid communication between the catheter and the collection container when the balloon is in a deflated state and terminate the fluid communication when the balloon is in an inflated state thereby preventing the output airflow device from drawing airflow out of the catheter.

8 . The drainage tube of claim 6 , wherein the membrane is a self-sealing membrane.

9 . The drainage tube of claim 6 , wherein the port is located at a distal end of the drainage tube.

10 . The drainage tube of claim 6 , further comprising:

a hydrophobic filter coupled in line with the drainage tube between the collection container and the output airflow device.

11 . A drainage system for draining a fluid from a patient, the drainage system comprising:

a catheter;

a collection container;

a drainage tube in fluid communication with the collection container;

an output airflow device coupled to the collection container configured to draw airflow out of the drainage tube; and

a connector tube configured to provide fluid communication between the catheter and the drainage tube, wherein the connector tube includes a port and a balloon attached to an interior of the connector tube by surrounding a membrane disposed on an interior side of the port, wherein an interior cavity of the balloon is configured to:

receive a gas from a needle that has pierced the port, the needle entering the interior cavity of the balloon, and

occlude a lumen of the connector tube.

12 . The system of claim 11 , wherein, when in an inflated state, the balloon occludes the lumen of the connector tube thereby breaking the fluid communication between the catheter and the collection container and preventing the output airflow device from drawing airflow out of the catheter.

13 . The system of claim 11 , wherein the membrane is a self-sealing membrane.

14 . The system of claim 11 , further comprising a hydrophobic filter coupled in line with the connector tube between the collection container and the output airflow device.
