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(1), which is disposed on the tube opposite the second end of the guide tube, is observed and the tube is subsequently withdrawn over a pre-determined distance, e.g. pulled out by 1 cm, and fixed in said position on the guide tube.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 situate d opposite the pipe. The sensitivity of the subject's pharynx, measured using the sensitive perception threshold, is determined using the lowest flow valu e perceived by the subject.
