Title: INSERTION DEVICE AND METHOD FOR OPERATING INSERTION DEVICE
Abstract:
The present invention includes: an endoscope (1); a first air supply unit (11); a first air suction unit (12); a second air supply unit (21); a second air suction unit (22); a pressure detection unit (60); an operation detection unit (51); and a control unit (50). The control unit (50) implements a first control process on the second air supply unit (21) and the second air suction unit (22) such that the amount of air supplied from the second air supply unit (21) is equal to the amount of air suction by the second air suction unit (22) per predetermined duration of time. When the operation detection unit (51) detects operation of the first air supply unit (11) or the first air suction unit (12) and the pressure detection unit (60) detects a pressure fluctuation in a subject from a first pressure to a second pressure, the control unit (50) maintains the first control process for supplying air into and sucking in air from the subject at the second pressure.
