Abstract: Aiming at the problems of existing needle-free syringes such as large volume, high noise, low injection efficiency, small driving force, and difficulty in adjustment, a magnetoresistive electromagnetic energy storage needle-free injection system  which adopted empty stroke energy storage method was designed. Electromagnetic drive part and ampoule liquid jet part of the injection system were simulated, and an experimental platform was established to further verify the correctness of theoretical design by experiments. The scheme greatly reduces volume of the needle-free injection system and enlarges adjustable range of driving forces. It is safe and stable, and may meet the injection requirements, which make the syringe has certain practicability and feasibility.

摘要: 针对现有无针注射系统体积大、噪声大、注射效率低、驱动力小且难以调节的问题,设计了一种采用空行程蓄能的磁阻式电磁蓄能无针注射系统。对注射器电磁驱动部分和安瓿药液射流部分进行了仿真研究,通过搭建的实验平台验证了理论设计的正确性。该方案极大地缩小了无针注射系统的体积、扩大了驱动力的可调范围,并且安全稳定,可以完成注射,具备一定的实用性和可行性。
