FLUID MANAGEMENT SYSTEM
First Claim
Patent Images
1. A fluid management system comprising:
- a pump configured to deliver a fluid from at least one fluid supply container to a site, said site being a surgical site or a patient;
a heater assembly for heating the fluid prior to delivery of the fluid to the site; and
a control system for operating the fluid management system according to operating parameters, said control system including a user interface for a user to select a plurality of default operating parameters associated with delivery of the fluid to the site, wherein said plurality of default operating parameters include;
establishment of either a pressure control mode or a flow control mode, wherein for the pressure control mode a default target pressure is established to control the pump to deliver fluid to the site, and wherein for the flow control mode a default target flow rate is established to control the pump to deliver fluid to the site,enablement or disablement of the heater assembly to heat the fluid, wherein if the heater assembly is enabled, then a default target temperature is established for heating the fluid delivered to the site according to the target temperature, andenablement or disablement of fluid deficit monitoring for determining a fluid deficit that is a difference between (i) a volume of fluid delivered to the site from the at least one fluid supply container and (ii) a volume of fluid returned from the site to at least one fluid collection container, wherein if the fluid deficit monitoring is enabled, then a default alarm limit is established that is indicative of a maximum fluid deficit, said control system activating a deficit alarm when the monitored fluid deficit exceeds the maximum fluid deficit.

Abstract
Fluid management systems and methods of operating fluid management systems which may provide one or more functions associated with suction, irrigation, distention, deficit monitoring, infusion, fluid warming, and the like. Some example embodiments may include infra-red lamps arranged to heat fluid flowing through a disposable cartridge. Some example embodiments may provide a three-dimensional fluid path through the cartridge and/or multi-stage heating capabilities. Some example fluid management systems may be selectable between pressure control and flow control modes.

17. 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. - View Dependent Claims (18, 19)

20. 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. - View Dependent Claims (21, 22, 23)
