| 摘要 |
The invention relates to a mouthpiece intended for a device that is used to assess the sensitivity of the pharynx of an individual. For this purpose, an open mouthpiece (1), which is fitted with a thin guide tube (2) having one articulated end (4), is inserted into the subject's mouth. A pipe (9) is introduced into the guide tube by means of the mouthpiece, under observation, until it touches the subject's palate. A measurement scale (1), which is disposed on the tube opposite the second end of the guide tube, is observed and the tube is subsequently withdrawn over a pre-determined distance, e.g. pulled out by 1 cm, and fixed in said position on the guide tube. A variable gas flow is injected into the pipe and reaches the pharyngeal mucous situated opposite the pipe. The sensitivity of the subject's pharynx, measured using the sensitive perception threshold, is determined using the lowest flow value perceived by the subject.
