电动无针注射器设计摘 要无针注射不同于传统的皮下注射，它是一种全新的注射方式，具有痛苦小、药物吸收好、操作方便、消除了交叉感染等诸多优点。我国对无针注射器的讨论起步较晚，在技术层面和国外先进水平存在不小差距，目前尚处于研发阶段。本文在分析无针注射器原理及结构的基础上，设计了电磁式无针注射器，主要讨论工作如下：1．对国内外无针注射技术的进展现状进行讨论，分析了无针注射的注射机理，运用工程设计学方法分析了无针注射器的结构特点，制定了无针注射器系统结构设计方案。2．设计的电磁驱动式无针注射器机构，来完成计量可控的给要注射，详细设计了由铁锤、弹簧和电磁铁所组成的撞击系统，以及安瓿头安装装置，机构简单，稳定性强。3．设计驱动和控制装置，完成沟通电变直流和控制电磁铁通断电等功能。4．根据以上设计，进行了三位建模，验证了设计的可行性，并为样机制作打下基础。所设计的电动无针注射器，冲击力大，注射效果好，注射计量可控，有很好的商业价值，值得推广应用。关键词 无针注射器；电磁铁；安瓿头Design of Electric Syringe Without NeedleAbstractCompared to conventional subcutaneous injection, the needle-free injection is a new way, with a painless, drug absorption, easy to operate, eliminating cross-infection and many other advantages. Domestic syringe without a needle of a late start, lagging behind foreign technology, is still in the research and development stage. In this paper, based on the analysis of a syringe without a needle structural characteristics, design the electric syringe without a needle, the main research work are as follows:1．Needle-free injection technology development status at home and abroad, needle-free injection mechanism, use of engineering science analysis of the structural characteristics of needle syringe, developed a syringe without a needle system structure design.2．Design of electromagnetic drive type syringe without needle agencies, to complete the measurement control for injection, the detailed design of the hammer, springs and e...
