Abstract
An endoscope system includes a valve configured to keep an internal space of an endoscope airtight, an air pump configured to open and close the valve by applying a negative pressure and a positive pressure, a pressure sensor configured to detect a pressure at a time of the negative pressure and the positive pressure being applied, and a control section configured to receive a detection signal from the pressure sensor, and perform drive control of the air pump.
Claims9
A leak detection processing apparatus comprising:
- one or more pumps configured to:
- be removably connected, via a pipe sleeve, to an internal space of an endoscope;
- apply negative pressure by air suction while connected to the internal space of the endoscope;
- and
- apply positive pressure by air feeding to disconnect the pipe sleeve from the endoscope;
- a pressure sensor configured to:
- detect a pressure in the internal space of the endoscope while the one or more pumps are connected to the internal space of the endoscope;
- and
- during or after application of the negative pressure by the one or more pumps, output a first detection signal indicating that a leak into the internal space of the endoscope has not occurred;
- and
- a controller configured to:
- control the one or more pumps to apply the negative pressure;
- receive the first detection signal;
- and
- control the one or more pumps to apply the positive pressure to disconnect the pipe sleeve from the endoscope.
