Abstract
A saliva ejector having a hollow tube including a cylindrical wall, a first end for placement within an oral cavity, and a second end for attachment to a suction hose. A flowpath is defined within the tube. The ejector includes a first corrugated portion defined in the cylindrical wall, a second corrugated portion defined in the cylindrical wall, and a filter element secured across the flowpath. The bending qualities of the first corrugated portion differ from the bending qualities of the second corrugated portion, thus allowing for a wide variety of bendable configurations.
