PROBLEM TO BE SOLVED: To provide a liquid pressure-feeding device for feeding water or dyeing liquid which is used with an endoscope for washing or dyeing an area to be observed by the endoscope, such as the stomach or the intestine, quickly, easily and efficiently. SOLUTION: The liquid pressure-feeding device for an endoscope has a pair of air supply tubes 4a and 4b derived from an air compressor 1. One air supply tube 4a is inserted into and connected airtightly to an insertion hole 5b of a plug body 5a of a watertight container 5, and the other air supply tube 4b is inserted into and connected airtightly to an insertion hole 6b of a plug body 6a of a dyeing liquid-tight container 6. At the same time, a water supply tube 7a derived from the watertight container 5 and a dyeing liquid supply tube 7b derived from the dyeing liquid-tight container 6 are connected to liquid inlet nozzles 8a and 8b of a switch cock 8 respectively. A liquid pressure-feeding tube 9 connected to a liquid outlet nozzle 8c of the switch cock 8 is inserted into a forceps insertion hole of an endoscope. COPYRIGHT: (C)2006,JPO&NCIPI
