Fluid infusion system

Abstract

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.
