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.

Un circuit d'écoulement est défini dans le tube. L'éjecteur comprend une première portion ondulée définie dans la paroi cylindrique, une deuxième portion ondulée définie dans la paroi cylindrique et un élément filtrant fixé en travers du circuit d'écoulement. Les propriétés de fléchissement de la première portion ondulée diffèrent de celles de la seconde portion ondulée, ce qui permet une grande variété de configurations de flexion.
