摘要： PROBLEM TO BE SOLVED: To provide a hypodermic needle assembly which reduces risk of unintentional exposure of a used needle by automatically engaging a needle shield without requiring a complex mechanism or operation by a user. SOLUTION: This syringe is equipped with two advancing mechanisms, and includes a syringe barrel 308 having a closing end part 311 with a syringe tip end part 314 and a bore; and a plunger 310 having an extension pin 316 and a plunger tip end part 318 through which the extension pin 316 penetrates. Two kinds of force are provided by the advancing mechanisms acting on the plunger. The first force acts on the plunger to move the plunger to a second position wherein the plunger tip end part 318 is in contact with the closing end part of the syringe barrel 308 and the second force acts on the plunger tip end part 310 to move to a third position with respect to the plunger tip end part. The extension pin 316 actuates a pressure trigger part to interact with a needle tip end block means of the needle assembly installed on the syringe. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种皮下注射针组件，其通过自动地接合针护罩而减少了无意中暴露使用过的针头的风险，而不需要使用者的复杂机构或操作。解决方案：该注射器配备有两个前进机构，并且包括注射器筒308，其具有带有注射器末端部314和孔的封闭端部311; 以及具有延伸销316和柱塞顶端部分318的柱塞310，延伸销316穿过该柱塞顶端部分318。作用在柱塞上的前进机构提供两种力。第一力作用在柱塞上以将柱塞移动到第二位置，其中柱塞顶端部318与注射器筒308的闭合端部接触，并且第二力作用在柱塞末端部310上以移动到相对于柱塞前端部的第三位置。延伸销316致动压力触发部分以与安装在注射器上的针组件的针尖端部块装置相互作用。版权所有（C）2009，JPO＆INPIT
