1. A saliva ejector comprising:
a four-faced, tapered saliva ejection tube; two anti-collapsing bosses; a friction fit connection sleeve; a placement leaf, said leaf having a uniform thickness; an angled extraction orifice; and a retention orifice; wherein said saliva ejection tube is a linear, hollow member with a high-end and a low-end having a top face, a bottom face, and two curved side faces, wherein said top face and said bottom face are planar and held in a spatial configuration that narrows in taper from said high-end to said low-end by said side curved side faces;
wherein said extraction orifice is formed therethrough said top face of said low-end of said ejection tube;wherein said anti-collapsing bosses are affixed to an interior surface and adjacent to said front end of said ejection tube;wherein said retention orifice is formed therethrough said bottom face of said low-end of said saliva ejection tube between said anti-collapsing bosses and said low-end of said ejection tube;wherein said friction fit connection sleeve has a first open end and a second open end, said first open end sized for frictionally engagement with a vacuum line of a slow-speed suction device, and said second open end affixed to said high-end of said saliva ejection tube;wherein said placement leaf is a flexible, ovate-shaped, flange with a planar body and an upward-curved front lobe; wherein said planar body extends around said ejection tube such that a longitudinal axis of said placement leaf is spatially common with a longitudinal axis of said saliva ejection tube, and wherein said extraction orifice and said retention orifice reside within the front lobe portion of said placement leaf. |
