Abstract
A cleaning adapter unit for connecting a cleaning fluid supply device to different type endoscopes comprises adapter valve assemblies which correspond to the different endoscopes, respectively. Each adapter valve assembly comprises a valve sleeve detachably connectable to the cleaning fluid supply device and a valve body received in the valve sleeve for slide movement and forming a valve chamber leading to the passage in the valve sleeve. The valve sleeve has a passage and is provided with a first fitting at one end thereof which is formed so as to be hermetically received in a valve casing of one of the different endoscopes, and the valve body is provided with first and second passages formed separately therein and opens at opposite ends, respectively, and with a second fitting at one ends thereof opposite to the one end of the valve sleeve at which the first fitting is formed so as to be hermetically received in the valve casing of the other different endoscope. The valve body brings the passage into communication with the first passage through the valve chamber when the cleaning adapter unit is attached to the one different endoscope by fitting the first fitting in the valve cas…
