    • The present invention relates to a safety syringe (100) having a hollow barrel (1), plunger (2) and a detachable needle support (4), characterized in that the safety syringe (100) includes; a) a piston gasket (3) interference fit with the plunger head (7) of the plunger (2); b) a plurality of bone structures (6) provided at the barrel head (1a) of the hollow barrel (1) to temporarily engage and support the needle support (4); c) a plurality of slots (8) longitudinally disposed at one substantial distal end of the needle support (4); and d) stoppers (5) provided at the barrel head (1a); wherein a fluid is injected by a first stroke of the plunger (2) under normal load; and an additional load is applied to the plunger (2) to compress the piston gasket (3) so that the plunger head (7) of the plunger (2) travels further to break the bone structures (6) for subsequent retraction of the needle support (4) on a second stroke.
    • 本发明涉及具有中空筒体(1),柱塞(2)和可拆卸针头支撑件(4)的安全注射器(100),其特征在于,安全注射器(100)包括: a)与柱塞(2)的柱塞头(7)过盈配合的活塞衬垫(3); b)设置在所述中空筒体(1)的所述筒头部(1a)处的多个骨结构(6),以暂时接合和支撑所述针支撑件(4); c)纵向设置在针支撑件(4)的一个实质远端的多个狭槽(8); 和d)设置在枪头头部(1a)处的塞子(5); 其中通过所述柱塞(2)的第一冲程在正常载荷下注入流体; 并且向柱塞(2)施加额外的负载以压缩活塞垫圈(3),使得柱塞(2)的柱塞头(7)进一步行进以破坏骨结构(6),以便随后针回缩 支持(4)第二行程。
