Abstract: A valve and irrigator used with a suction tube has an elongate funnel with an axis through an enlarged entrance and an opposed extended exit duct of a flexible elastomer. A flow passage through the elongate funnel connects the entrance to the exit permitting fluid communication. A web across and near the enlarged entrance sealingly separates that from the exit. The web and the elongate funnel are made of silicone elastomer and are adhesively adhered to together. A portal in the web passes therethrough along the axis and is circular in shape to surround in fluid tight engagement the suction tube. A lid, proximally of the web on the enlarged entrance, has an inlet for irrigation and a pass through for the tube; the lid closes the enlarged entrance forming a chamber between the web and the lid. A slit within the web, near the portal and spaced from the axis is in the form of a closed mouth composed of a pair of sealing lips.
