Abstract
A disposable saliva ejector for connection with a slow-speed suction device has a suction end and a discharge end. The tapered ejector has an ovate shape. A retention orifice helps secure the ejector within the patient's mount, while a larger extraction orifice removes fluid and debris. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions. The discharge end connects to a discharge tube, wrapping around the oral commissure then hooking onto the patient's outer cheek. Once properly placed within the patient's mouth the dental assistant is relieved from providing suction during various procedures.
Claims12
A saliva ejector comprising:
- a saliva ejection tube;
- a least one anti-collapsing boss;
- a friction fit connection sleeve;
- a placement leaf;
- an extraction orifice;
- and
- a retention orifice;
- wherein said saliva ejection tube is a linear, hollow member with a front end and a back end;
- wherein said extraction orifice is formed therethrough said front end of said ejection tube;
- wherein at least one said anti-collapsing boss is affixed to said interior surface and adjacent to said front end of said ejection tube;
- wherein said retention orifice is formed therethrough said front end of said saliva ejection tube between said anti-collapsing boss and said front 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 back end of said saliva ejection tube;
- wherein said placement leaf is a flexible generally planar ovate configured flange that 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.
A saliva ejector comprising:
- a discharge tube;
- a saliva ejection tube;
- a least one anti-collapsing boss;
- a friction fit connection sleeve;
- a placement leaf;
- an extraction orifice;
- a retention orifice;
- wherein said discharge tube has a distal and proximate end said distal end connectable to a low-speed suction device and said proximate end rigidly formed into a bend so that the included angle on said discharge tube is acute;
- wherein said saliva ejection tube is a four-faced, linear, hollow member 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 a back end to a front end of said ejection tube by said side faces;
- wherein said extraction orifice is formed therethrough said top and said side faces at said front end of said ejection tube;
- wherein said retention orifice is formed therethrough said bottom face of said saliva ejection tube between said anti-collapsing boss and front end of said ejection tube;
- wherein at least one said anti-collapsing boss is affixed to said interior surface and adjacent to said front 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 said proximate end of said discharge tube, and said second open end affixed to said back end of said saliva ejection tube;
- wherein said placement leaf is a flexible generally planar ovate configured flange that extends normally therefrom said curved side faces of said saliva ejection tube such that a longitudinal axis of said placement is spatially common with a longitudinal axis of said saliva ejection tube;
- and
- wherein said discharge tube is removeably connected to said saliva ejection tube through said friction fit connection sleeve.
