Mouth piece for suction of exhaled air from e.g. a dental patient, at which the mouth piece is to be applied close below the mouth of the patient and showing one or several suction openings (2, 3, 4), and is connected to a suction conduit (6), showing members (7, 8) extending to the patient, which are intended to be brought into the mouth of the patient resting to the inner side of the mouth cavity in that way that the mouth piece is kept at the mouth. The projecting members include two sideways from the mouth piece projecting wings (7), which are resting to the inner side of the patient's cheeks when they are brought into the mouth. |
