Patent abstract

Disclosed herein are systems and methods directed to an assisted fluid drainage system including one or more ejector vacuum pumps disposed in-line with the drainage tube. The one or more pumps can use a venturi effect vacuum pump to draw a fluid in and urge the fluid through the drainage tube to prevent the formation of dependent loops. Dependent loops can form within fluid drainage tubes when slack portions of tube create a positive incline. These dependent loops trap fluid and can create a retrograde flow, leading to various complications such as catheter associated urinary tract infections (“CAUTI”). Advantageously, the pumps can operate while the drainage lumen remains in fluid communication with the catheter. As such the pumps can operate continuously to prevent dependent loops from establishing.
