    • PROBLEM TO BE SOLVED: To provide a small-sized air sending device easily prepared and capable of sending two or more kinds of gases by one device. SOLUTION: The air sending device 40 comprises: a first pipeline for supplying a laughing gas which is a first prescribed gas supplied from a laughing gas cylinder 43 as a first supply source into a first body cavity of a patient; a second pipeline for supplying carbon dioxide which is a second prescribed gas supplied from a carbon dioxide cylinder 42 as a second supply source to the first body cavity of the patient or a nearby second body cavity; and a first electropneumatic proportional valve and a second electropneumatic proportional valve as pressure adjusting means for adjusting the respective pressures of the gases supplied from the laughing gas cylinder 43 and the carbon dioxide cylinder 42 through the first pipeline and the second pipeline to the patient.

    • PROBLEM TO BE SOLVED: To provide an air-feeding apparatus where excessive feeding of gas fed into a body cavity of a living body is saved by setting the target pressure and target capacity of the gas to be fed into the body cavity. SOLUTION: The air-feeding apparatus is provided with: an air-feeding means for feeding the prescribed air from a feeding source of the prescribed gas into the body cavity; a first setting means for carrying out setting input of a target capacity value in order to increase the capacity in the body cavity to be the prescribed capacity by feeding the gas; a second setting means for carrying out setting input of a target value of the pressure of the gas to be fed into the body cavity; a first detection means for detecting the flow rate of the prescribed gas fed into the body cavity by the air-feeding means; a second detection means for detecting the pressure of the prescribed gas fed into the body cavity by the air-feeding means; and a control means for controlling the air-feeding means so that the capacity value in the cavity in the case of feeding the gas may match with the target capacity value set by the first setting means, based on the detecting results obtained by the first and second detection means.
