Abstract
An air and liquid supplying device for an endoscope has a main body with a connecting portion and an air pump arranged in the main body. A first switch control valve is connected to an air supply channel and a liquid supply channel of the endoscope. A universal cord is connected at one end to a control section of the endoscope and at the other end to the connecting portion through a connector. A first air feed path extends from the first valve to the end of the connector through the universal cord. A liquid feed path extends from the first valve through the universal cord and communicates with a first liquid supply tank. The air pump is connected to the connecting portion through a second air feed path. A second liquid supply tank including second liquid is connected to the second air feed path. A second switch control valve is connected to the second air feed path to switch between the supply of air and the supply of the second liquid to the second air feed path. When the connector is not connected to the connecting portion, leakage of the second liquid through the connecting portion is prevented by a leakage preventing device.
