    • PROBLEM TO BE SOLVED: To provide a disposable syringe of a module design having a small whole size, including only a small number of structure parts, easily handled, and on the other hand, ensuring safe storage and reliable operation.SOLUTION: A disposable syringe includes: at least one mechanical spring energy storing part 50; at least one piston-cylinder unit 100 for enabling effective filling at least at a certain time; at least one piston operation shaft 60; and an enclosure 10 in which at least one starting unit 80 is disposed. The spring energy storage part includes at least one spring element to which tension is previously applied. The piston-operation shaft worked by a spring includes at least one pull-out rod which can move in the lateral direction at least in a certain area, and supports the spring energy storage part in which tension is applied to the surface of at least one still surface of the enclosure by a support part 65. When the operation occurs, a starting element 82 opens a support part, and separates from the still surface to move it.
    • 要解决的问题:提供具有小尺寸的模块设计的一次性注射器,其仅包括少量结构部件,容易处理,另一方面确保安全储存和可靠的操作。解决方案:一次性注射器 包括:至少一个机械弹簧能量存储部分50; 至少一个活塞缸单元100,用于至少在一定时间有效地填充; 至少一个活塞操作轴60; 以及设置有至少一个起动单元80的机壳10。 弹簧储能部分包括至少一个预先施加张力的弹簧元件。 由弹簧加工的活塞操作轴至少包括至少一个可在至少一定面积上沿横向方向移动的拉出杆,并支撑弹簧能量储存部分,其中张力施加到至少一个的表面上 当操作发生时,启动元件82打开支撑部分,并从静止表面分离以使其移动。
