In one embodiment, the present disclosure is directed to a high volume suction tip, including a tubular body with peripheral side wall, a functional orifice, and a vacuum source end. An aperture in a wall of the tubular body forms a vacuum release orifice, wherein the aperture is between the functional orifice and the vacuum source end. A plurality of tubes are placed within a lumen of the tubular body, wherein the tubes have a longitudinal axis substantially parallel to a longitudinal axis of the tubular body and provide at least one channel for transmitting a material from the functional orifice to the vacuum source end. A first tube occludes the vacuum release orifice at a first pressure, and, at a second pressure lower than the first pressure, a compressible side wall of a second tube collapses inwardly to disengage the first tube from the vacuum release orifice. |
