Abstract
Systems and methods directed to an assisted fluid drainage system including a proximal ejector pump and a distal ejector pump coupled to a drainage tube. At least one of the proximal ejector pump and the distal ejector pump can utilize a venturi effect to move a bodily fluid through the drainage tube to prevent the formation of dependent loops, which can form within fluid drainage tubes when slack portions create a positive incline. At least one of the proximal ejector pump and the distal ejector pump can include a converging section, a diffuser section, and a diverging section. A diameter of the diffuser section can be less than a diameter of the converging section or the diverging section. A controller can be coupled to the proximal ejector pump and the distal ejector pump to initiate operation of one or both of the pumps in response to an event.
