    Abstract: An insufflation system includes an insufflation device for supplying gas to a body cavity, and a suction device for suctioning the gas from the body cavity through a suction conduit at a suction flow rate. The insufflation device includes a flow rate sensor for measuring a gas feeding flow rate, a pressure sensor for measuring body cavity internal pressure, a first on-off valve for controlling the gas feeding flow rate, a second on-off valve for opening and closing the suction conduit, and a processor for opening the second on-off valve and controlling the first on-off valve to feed the gas at an amount when a first target gas feeding flow rate calculated from difference between the body cavity internal pressure and insufflation target pressure is lower than a threshold flow rate, the amount being obtained by adding the suction flow rate to the first target gas feeding flow rate.

    Abstract: An insufflation device includes: a gas feeding conduit for feeding a predetermined gas which is fed from a gas supply source into a body cavity; and a processor. The processor measures a gas feeding time period until a predetermined amount of the gas is fed according to a set pressure, measures a pressure in the body cavity, calculates a gas discharging time period based on the set pressure and a measurement result of the measured pressure; and adjusts a gas feeding flow rate of the gas according to a difference between the measured gas feeding time period and the calculated gas discharging time period.
