Abstract
A disposable saliva ejector with a single planar, double leaf shaped plate design embossed on the inner faces of the leaf plates with a series of arced ribs and then folded about its midpoint. A tab and slot arrangement joins the two plates when operationally folded. The arced ribs form a series of channels equidistant about the perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. 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.
Claims15
A saliva ejector comprising:
- a pair of generally ovate shaped plates, having a linear axis, distal ends, proximal ends, an inner face and an outer face, and perimeter edges;
- a suction connection tube disposed between said plates and residing adjacent to said proximal ends, said connection tube having a vacuum connection end and a saliva inlet end;
- an open trough formed thereon said inner faces residing along said linear axes;
- a series of channels formed on said plates, said channels leading from said perimeter edge of the device to the trough, said channels exiting between said plates;
- wherein said planar plates are hingedly attached at said proximal ends so as to allow a folding between an assembled and unassembled saliva ejector.
A saliva ejector comprising:
- a first leaf shaped inner plate and a second leaf shaped cheek plate, each having distal ends, proximal ends, an inner face and an outer face, and identically shaped perimeter edges;
- a suction connection tube with a pair of gusset plates extending normally from opposite sides of said connection tube, said connection tube having a vacuum connection end and a saliva inlet end, wherein said proximal ends of said first leaf shaped plate is hingedly affixed to a first side of said gusset plates and said second leaf shaped plate is hingedly affixed to a second side of said gusset plates;
- a pattern of raised ribs formed thereon said inner faces, wherein said pattern of ribs on said first leaf and said pattern of embossings on said second leaf are not identical patterns;
- a groove formed along a linear centerline of said plates, said groove dimensioned to accept said saliva inlet end of said connection tube;
- wherein said saliva ejector may be assembled by folding said first plate and said second plate about said gusset plates to place said plates into a parallel, spaced configuration wherein a series of open channels are formed between adjacent ribs and between first leaf shaped inner plate and a second leaf shaped cheek plate, said channels exiting said saliva ejector between said plates along said perimeter edge.
