Disposable dental saliva ejector |
摘要 |
A disposable dental saliva ejector with a suction part (20C), at least one suction orifice (20') in the suction part, a holder part (20A) and a curved intermediate part (20B) has a tongue holder attached to the suction part and a chin plate (12) displaceably mounted on the holder part. The holder part defines a trough-shaped guiding channel for a duct means (21) and the chin plate has a mounting sleeve (12A) with a specifically shaped opening enabling the chin plate to occupy a central position and two opposite lateral positions, and to be temporarily fixed in a selected height position on the holder part. The tongue holder comprises a frame structure (201) which projects from the suction part in the direction away from the chin plate and is adapted to carry a disposable filter element in the shape of a flat filter bag (14), the suction orifice opening into the inner space of the frame structure. <MATH> |
