Method and apparatus for a valve and irrigator

A valve and irrigator for use in combination with a suction tube and irrigation, the valve and irrigator comprising:

• an elongate funnel having an axis;
• an enlarged entrance on the elongate funnel;
• an extended exit duct on the elongate funnel opposite the enlarged entrance and along the axis, the extended exit duct merging with the enlarged entrance, the exit duct is made of a flexible elastomer so the suction tube therethrough when bent will flex the exit duct to angle therewith off axis therealong;
• a flow passage through the elongate funnel, the flow passage connecting the enlarged entrance to the extended exit duct for permitting fluid communication therethrough;
• a merger between the enlarged entrance and the extended exit duct;
• a cavity between the enlarged entrance and the merger with the extended exit duct;
• a web across the cavity near the enlarged entrance for sealingly separating the enlarged entrance from the extended exit duct, the web is substantially normal to the axis, the web and the elongate funnel are made of silicone elastomer and are adhesively adhered to together, the web is bonded within the cavity near the enlarged entrance;
• a portal in the web, the portal passing therethrough along the axis, the portal is circular in shape and surrounds in fluid tight engagement the suction tube placed therethrough, the portal includes a cuff having an opening to receive the suction tube;
• a lid disposed proximally of the web and across the enlarged entrance, the lid having an inlet for receiving irrigation and a pass through for the suction tube, the lid closing the enlarged entrance forming a chamber between the web and the lid, and
• a slit within the web, near the portal and spaced from the axis, the slit in the form of a closed mouth composed of a pair of sealing lips normally together but able to separate and define a passageway for fluid flow through the web, and
• a peripheral bump radially disposed relative to the slit and on the enlarged entrance in position to align flexure force therethrough and toward the axis to distort the pair of lips into a pursed and therefore open configuration from their normally closed position, the orientation of the portal and the peripheral bump are substantially diametrical with respect to one another and the axis.

A method of using a valve and irrigator with a suction tube, the method comprising the following steps:

• locating an elongate funnel along an axis with an enlarged entrance on the elongate funnel;
• positioning an extended exit duct on the elongate funnel opposite the enlarged entrance and along the axis;
• merging the extended exit duct with the enlarged entrance;
• permitting fluid communication through a flow passage of the elongate funnel between the enlarged entrance and the extended exit duct;
• sealingly separating a cavity between the enlarged entrance and a merger with the extended exit duct with a web across the enlarged entrance;
• passing a portal through the web along the axis so the portal surrounds in fluid tight engagement the suction tube placed therethrough;
• spacing a slit within the web, near the portal so the slit is spaced from the axis with the slit in the form of a closed mouth composed of a pair of sealing lips normally together but able to separate and define a passageway for fluid flow through the web, and
• disposing radially on the enlarged entrance a peripheral bump in position to align flexure force therethrough and toward the axis to distort the pair of lips into a pursed shape and therefore open configuration from their normally closed position.
