Patent attributes
Embodiments disclosed herein are directed to a dynamic response drainage and occlusion system configured to drain a fluid from a patient. The drainage system includes an input airflow device to provide airflow into the drainage lumen, a pressure sensor to measure pressure within the drainage tube, and an output airflow device to provide airflow out of the drainage tube. A controller including control logic configured to acquire pressure data from the pressure sensor, determine a running pressure rate-of-change from the acquired pressure data, compare the running pressure rate-of-change with a pressure rate-of-change defined by the control logic, and adjust an operating characteristic of at least one of the input airflow device and the output airflow device to move the running pressure rate-of-change toward the pressure rate-of-change defined by the control logic. The system further includes catheter occlusions systems to automatically protect the patient from pressure spikes within the system.
