PROBLEM TO BE SOLVED: To propose a convenient-handling syringe including a main cylinder A wherein a needle C is fixed to the tip through a mounting member B, and a plunger D sectioning a fill space of a fluid inside the main cylinder and discharging the fluid from the tip of the needle by the slide thereof, allowing safe disposal by covering the tip of the needle after use, and allowing the use in a compact state in time of the use.SOLUTION: This syringe includes a fixing member E including a safe disposal means allowing the safe disposal in a state that the tip of the needle C after the use is covered. In the member, a lower fixing cylinder 30 and an upper fixing cylinder 50 supported in a state that the needle C penetrates from a top part, in a position above the lower fixing cylinder 30 and separate from the lower fixing cylinder 30 are connected through separating arms 70 each including an easy cut part 71, and extensible connection rods 80 are bridged between the lower fixing cylinder and the upper fixing cylinder. In the safe disposal means, the easy cut parts 71 are cut in time of the disposal, thereafter the connection rods are extended, the upper fixing cylinder is raised, and the tip of the needle can be locked to the rear face of the top part of the upper fixing cylinder.COPYRIGHT: (C)2013,JPO&INPIT【課題】先端に装着部材Bを介して注射針Cを固定した主筒Aと、主筒内に流体の充填空間を画成してその摺動にて流体を注射針の先端から排出するプランジャDとを備えた注射器であって、使用後に注射針の先端を被覆して安全な廃棄が可能であり、しかも使用時にはコンパクトな状態での使用が可能であり、その取り扱いも便利な注射器を提案する。【解決手段】使用後の注射針Cの先端を被覆しての安全廃棄が可能な安全廃棄手段を備えた固定部材E設けている。該部材は、下部固定筒30と、下部固定筒上方離間位置に、注射針Cを頂部より貫通させた状態で支持した上部固定筒50とを、易切断部71を備えた離間用腕70を介して連結し、下部固定筒と上部固定筒間に伸長が可能な連結杆80を掛け渡し、安全廃棄手段として、廃棄時に易切断部71を切断した後、連結杆を伸長させて上部固定筒を上昇させ、上部固定筒の頂部裏面に注射針の先端を係止可能に構成した。【選択図】図1
