PROBLEM TO BE SOLVED: To provide a combined container-injection syringe capable of being handled easily with one hand and without requiring complicated operation in use.SOLUTION: In a combined container-injection syringe, a cylindrical opening part as a finger grip attached to a rear end of an injection cylinder becomes narrower from the rear end of the injection cylinder to a tip end thereof, and a guide cylinder into which a plunger rod is inserted has a stop projection part projecting diagonally outside and forward so as to open in a direction from a rear end of the guide cylinder to a tip end thereof in relation to a longitudinal axis line. An accommodating projection part which projects to a direction of a body of the plunger rod is provided internally in the stop projection part, and the body of the plunger rod has an accommodating groove for receiving the accommodating projection part, the accommodating projection part of the guide cylinder being in contact with the body of the plunger rod.COPYRIGHT: (C)2014,JPO&INPIT【課題】使用に際して複雑な操作を必要とせず、片手で簡単に取り扱うことのできる容器兼用注射器を提供すること。【解決手段】注射筒の後端に取り付けられたフィンガーグリップの筒状開口部が、前記注射筒の後端から前記注射筒の先端方向に狭くなり、プランジャーロッドが挿通している誘導筒が、長軸線に対して前記誘導筒後端から前記誘導筒先端方向に開くように斜め外前方へ突き出た停止突起部を有し、前記停止用突起部の内側に、前記プランジャーロッド本体方向へ突き出た格納用突起部が設置されていて、前記プランジャーロッド本体が、前記格納用突起部を受け入れる格納溝を有し、前記誘導筒の格納用突起部が、前記プランジャーロッド本体と接触していることを特徴とする容器兼用注射器。【選択図】図1
