| Abstract: |
A single-use annular mouthpiece for use with a diagnostic instrument such as an endoscope is provided. The mouthpiece protects the endoscope from damage and enhances patient comfort while giving a visible indication of any prior use. The mouthpiece includes a first relatively rigid portion having an annular main body shaped and dimensioned to be held in a patient's mouth and to provide clearance for an instrument through its central opening. The rigid portion includes an annular lip extending radially from the main body at one end and an annular flange extending radially from the main body at another end. The flange is shaped and dimensioned to overlie a patient's lips. The mouthpiece includes a second deformable compressible annular portion mounted around the annular main body of the first portion. The second portion is permanently deformable when subject to a patient'bite. The second portion is sized and shaped to substantially encircle the main body portion and to fit between the lip and the flange. The outer periphery of the lip extends no further than the outer surface of the second compressible annular portion.

What is claimed:
1. A single-use annular mouthpiece comprising:
- a relatively rigid portion including an annular main body shaped and dimensioned to be held in a patient's mouth and to provide clearance for tubing through its central opening,
- an annular lip extending radially out from said main body at one end thereof,
- an annular flange extending radially out from said main body at the other end thereof, said flange being shaped and dimensioned to overlie a patient's lips; and
- a compressible annular portion severable from and mounted around to overlie said annular main body of said rigid portion,
- said portion being sized and shaped to encircle said main body portion and to fit between said lip and said flange,
- the outer periphery of said lip extending radially out no further than the outer surface of said compressible annular portion,
- whereby said mouthpiece is usable in medial and surgical procedures which require both protection for tubing used with the mouthpiece and protection for the patient undergoing the procedure.
