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: A connection unit for air feeding tube is a connection unit to which an air feeding tube is connectable and fixable and which includes: a first pipe having an opening through which gas from the air feeding tube flows in; a second pipe that is configured to be arrangeable substantially parallel to a surface of a bed used in an examination, and includes an opening through which the gas flows out; and an air feeding flow path which is formed to include the two openings and through which the gas is fed. When the air feeding tube is fixed to the connection unit for air feeding tube and is used, a part of the air feeding flow path for the gas is formed so as to pass through an area located at a position opposite to a gravitational direction with respect to a central axis of the second pipe.
