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. |
