Abstract
A saliva ejector tip system, which prevents the problem of backflow when a patient closes his lips around an ejector tip, includes seal-interfering structural features on the outer surface of an ejector tip. A tip holder carried by a saliva elector hand tool couples with the proximal end of the tip in vacuum-tight engagement.
Claims12
A saliva ejector tip system, comprising:
- an ejector tip holder mountable to the distal end of a saliva ejector hand tool, whereby to present a socket at the distal end of said hand tool;
- and
- an ejector tip, having:
- a proximal end, insertable into said socket;
- a distal end, terminating in a suction-delivery element;
- and
- a tubular section between said proximal and distal ends of said ejector tip, having external surface configurations forming a means for interfering with a sealing interface between said tubular section and the lips of a patient circumscribing and pressed against said outer surface.

A saliva ejector tip system, comprising:
- an ejector tip holder element carried at the distal end of a saliva ejector hand tool;
- and
- an ejector tip, having:
- a proximal end, adapted to couple with said tip holder element;
- a distal end;
- and
- a tubular section between said proximal and distal ends of said ejector tip, having external surface forming a means for interfering with a sealing interface between said tubular section and the lips of a patient circumscribing and pressed against said outer surface.
