A device for sealing an endoscope channel is provided in the operation section of an endoscope and comprises a hollow cylindrical member connected at one end to the proximal end of a channel disposed in the sheath of the endoscope and a tubular member of an elastic material disposed in the hollow cylindrical member and connected at one end sealingly to the other end of the hollow cylindrical member. The other end portion of the tubular member is bent to form a sealing portion which can prevent air introduced into a body cavity from flowing back therefrom through the channel. |
