Abstract: A gas feeding apparatus configured to supply the gas to a lumen of a patient through a gas feeding conduit provided in an endoscope, the gas feeding apparatus including: a flow rate sensor configured to measure a flow rate of the gas in the gas feeding conduit; and a control circuit configured to time-sequentially calculate an integrated amount of the gas fed to the lumen in a period from a first timing to a second timing, the first timing being a timing when the gas starts to be fed from the gas feeding conduit to the lumen by an operation of a gas feeding button of the endoscope, the second timing being different from the first timing. The control circuit controls a notification unit to activate an alarm, when the integrated amount of the gas reaches the first threshold.

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.

Abstract: An endoscope system includes a gas feeding apparatus that feeds carbon dioxide, and a light source apparatus provided with an air pump for supplying air. The endoscope system feeds the carbon dioxide or the air from a distal end of an endoscope when a gas/liquid feeding button provided to the endoscope is operated. The endoscope system includes a pressure meter and a processor. The pressure meter is provided inside the gas feeding apparatus and configured to detect a pressure of the carbon dioxide. The processor is configured to perform control for stopping feeding of the air by the air pump when determining that, after the carbon dioxide is fed by an operation of the gas/liquid feeding button, the pressure of the carbon dioxide detected by the pressure meter reaches a predetermined threshold.
