摘要：
PROBLEM TO BE SOLVED: To provide a syringe and a mounting fixture which can easily feed a target amount of liquid selectively only when necessary.SOLUTION: A syringe 400 has: an outer cylinder 110 which can be filled with liquid inside a plunger 120 which is movable along the longitudinal direction of the outer cylinder 110 inside the outer cylinder 110 and in which a plurality of recessed parts 126B and projected parts 126A arranged in the longitudinal direction are formed an annular part 431 in an annular shape which can be mounted on the outer cylinder 110 by inserting the plunger 120 from the proximal end direction of the plunger 120 protrusion parts 432A, 432B which are brought into successive and slidable contact at least with a plurality of recessed parts 126A as the plunger 120 moves and a mounting fixture 430 provided with a rotation regulation part 433 which comes in contact with the plunger 120 to regulate rotation of the plunger 120 with respect to the outer cylinder 110.COPYRIGHT: (C)2014,JPO&INPIT【課題】必要な場合にのみ選択的に、目的の量の送液を容易にすることが可能なシリンジおよび装着具を提供する。【解決手段】内部に液体を充填可能な外筒110と、前記外筒110内で当該外筒110の長手方向に沿って移動可能であり、長手方向に並ぶ複数の凹部126Bおよび凸部126Aが形成された押し子120と、前記押し子120の基端方向から当該押し子120を挿通させて前記外筒110に装着可能な環形状の環状部431、前記押し子120の移動に伴い少なくとも前記複数の凸部126Aと順次滑動可能に接触する突起部432A,432B、および前記押し子120と接して当該押し子120の前記外筒110に対する回転を規制する回転規制部433を備える装着具430と、を有するシリンジ400である。【選択図】図19
