Fluid management system

Abstract

Fluid management system and method of operating a fluid management system which may provide one or more functions associated with suction, irrigation, distention, deficit monitoring, infusion, fluid warming, and the like. The fluid management system may be selectable between pressure control and flow control modes.

Having described the invention, the following is claimed: 
     
         1 . A fluid management system comprising:
 a pump configured to deliver a fluid from at least one fluid supply container to a body cavity;   a remote pressure sensor configured for placement in or proximate to a body cavity; and   a control system operatively connected to the pump and the remote pressure sensor, the control system receiving from the remote pressure sensor a signal associated with a pressure of the fluid at the location of the remote pressure sensor, and adjusting a speed of the pump to maintain a desired fluid pressure based at least in part upon the signal received from the remote pressure sensor.   
     
     
         2 . The fluid management system of  claim 1 , wherein the control system receives at least one of a pneumatic signal and an electrical signal from the remote pressure sensor. 
     
     
         3 . The fluid management system of  claim 1 , wherein said fluid distends the body cavity. 
     
     
         4 . A method for operating a fluid management system, the method comprising:
 delivering fluid from a fluid supply container to a body cavity via a tubing set;   sensing a system fluid pressure in the tubing set at a location between the fluid supply container and the body cavity;   sensing a site fluid pressure using a remote pressure sensor disposed in or proximate to a body cavity; and   controlling a pressure of the fluid delivered to the body cavity based at least in part upon at least one of (i) the sensed system fluid pressure and (ii) the sensed site fluid pressure.   
     
     
         5 . The method of  claim 4 , wherein controlling the pressure of the fluid delivered to the body cavity is based at least in part upon both (i) the sensed system fluid pressure and (ii) the sensed site fluid pressure. 
     
     
         6 . The method of  claim 4 , wherein said fluid delivered to the site via the tubing set distends the body cavity. 
     
     
         7 . The method of  claim 4 , wherein the tubing set comprises a disposable tubing set including a pressure relief valve.
