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 gas feeding apparatus communicating with a gas feeding source that feeds a predetermined gas and configured to supply the gas to a lumen of a patient through a gas feeding conduit provided in an endoscope includes: a gas feeding bottle provided between the gas feeding apparatus and the gas feeding conduit of the endoscope, and having the gas reserved; and a control circuit configured to detect a timing of start of decrease in a state where a predetermined value is kept, and configured to control a gas feeding amount from the gas feeding bottle to the gas feeding conduit, at the detected timing.

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.
