PROBLEM TO BE SOLVED: To provide a suction tip which has a simple structure, is mounted on the distal end of a suction pipe during a dental treatment, efficiently sucks cutting debris of teeth, droplets, liquids in an oral cavity, or the like simultaneously, and is ergonomically excellent.SOLUTION: The suction tip 1, which is mounted on the distal end of the suction pipe 10 during the dental treatment and sucks cutting debris of teeth, droplets, liquids in an oral cavity, or the like, is formed of a flexible member, and comprises a cylindrical base material part 2 having a prescribed inner diameter and a small-diameter pipe part 3 which is fixed by being inserted a prescribed length in an eccentric state where the proximal end part is inscribed to or partially buried in the inner wall of the base material part 2 from the distal end of the base material part and has a distal end part 3a protruding a prescribed length from the distal end 2c of the base material part 2. Furthermore, the base material part 2 has a protruding part 2a cut to form a shape of a slanting surface in the longitudinal direction in a manner that a distal end lower half part where the small diameter pipe part 3 is inscribed protrudes to the front.COPYRIGHT: (C)2008,JPO&INPIT【課題】 簡潔な構造で、歯の治療時に吸引パイプの先端に取付けられ、歯の切削屑、飛沫及び口腔内液体等を同時的に効率よく吸引することができるとともに人間工学的に優れた吸引チップを提供する。【解決手段】 歯の治療時に吸引パイプ10の先端に取付けられ、歯の切削屑、飛沫及び口腔内液体等を吸引する吸引チップ1であって、いずれも可撓性部材からなり、所定内径の略円筒状の基材部2と、後端部が前記基材部の先端から基材部2の内壁に内接又は一部埋設した偏心状態で所定の長さ挿入されて固設され、先端部3aが基材部2の先端2cから所定長さ突出した小径管部3とから構成される。また、基材部2は、小径管部3が内接する先端下半部が前方に延出するように長手方向傾斜面状にカットされた延出部2aが形成される。【選択図】図9
