Abstract
Embodiments disclosed herein are directed to a drainage system for draining a fluid from a patient where the system includes a drainage tube that provides fluid communication between a catheter and a collection container. The drainage tube includes a port and a balloon attached to an interior of the drainage tube, where the balloon is configured to receive air from a needle that has pierced the port and occlude a lumen of the drainage tube. 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. The balloon may be attached to the interior of the drainage tube by surrounding an interior side of the port.
