PROBLEM TO BE SOLVED: To provide a liquid suction tool which ensures a suction amount and also reduces adsorption of a soft tissue in suction of liquid such as saliva.SOLUTION: A liquid suction tool 1 includes: a cylindrical base body 10 including a suction space 14 inside for suctioning liquid such as saliva from a body and extended in a predetermined length direction plural protrusions 12B, 12E formed while protruding from an outer peripheral face 10A of the base body, arranged at an interval in an outer peripheral direction of the outer peripheral face of the base body, and extended in the predetermined length direction and outer peripheral suction ports 18A3, 18A4, 18A5, 20A3, 20A4, 20A5 arranged on the outer peripheral face of the base body between adjacent two protrusions among the plural protrusions and communicating with the suction space. The length of a protrusion range, in which each protrusion of the plural protrusions is extended in a direction along the predetermined length direction, is larger than the length of the base body in a direction orthogonal to the predetermined length direction.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】唾液などの液体を吸引する際に、吸引量を確保しつつ、柔らかい組織が吸着することを低減する液体吸引具を提供する。【解決手段】液体吸引具1は、体内から唾液などの液体を吸引するための吸引空間14を内部に有し、所定の長手方向に延びる筒状の基体部10と、基体部の外周面10Aから突出して形成されるとともに、その基体部の外周面の外周方向に間隔をあけて配置され、所定の長手方向に沿って延びる複数の突条部12B、12Eと、複数の突条部のうちの隣り合う2つの突条部の間において基体部の外周面に配置され、吸引空間に連通する外周吸引口18A3、18A4、18A5、20A3、20A4、20A5と、を備える。複数の突条部の各突条部が所定の長手方向に沿う方向に延びる突出範囲の長さは、所定の長手方向と直交する方向の基体部の長さより大きい。【選択図】図6
