Fluid management systems and methods
Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.
