A guide tube assembly is disclosed which serves both as a guide tube for an endoscope and a suction tube for anesthesia. The guide tube assembly comprises a tube, said tube being made of a porous fluoric resin on which a fluorocarbon elastomer is coated for a sealing material, a mouthpiece which is a body of revolution, said mouthpiece comprising a connector portion for holding the tube, an extended portion which spreads from the connector portion and a mouthpiece portion. By these constructions, the assembly can be freely curved by the endoscope and effectively serves both as the guide tube for the endoscope and the anesthetic suction tube. |
