摘要
为解决当前医用高压注射器注射药液时因注射速度快、压力高而易发生渗漏的问题,采用TI公司的微控制器MSP430F449及精量电子FS2050压力传感器,设计了一套高压注射器防渗漏智能导流报警系统,可实时监测高压注射过程。一旦监测到渗漏立即进行声光报警,同时迅速进行导流切换。本系统不仅克服了以往机械设计方案易松动的缺点,而且还增加了导流切换功能可有效减轻病人的痛苦。动物实验结果表明,智能导流报警系统稳定可靠、灵敏度高,可有效避免高压注射器的药液渗漏现象的发生。
The leakage of high-pressure syringe is usually happened during the course of clinical applications due to its rapid injection speed and high pressure.Based on Texas Instrument（TI）＇s microcontroller MSP430F449 and Measurement Specialties Inc（MEAS）＇s pressure sensor FS2050,an intelligent diversion alarm system is designed to prevent the leakage of high-pressure syringe designed.The system can offer real-time monitoring for the full injection process,and start sound light alarm,switch diversion immediately once the leakage is monitored.The intelligent system can not only overcome the shortcomings of easy to loose on mechanical designs,but also increase the switching function which can effectively reduce the pain of patients.Animal experimental results show that the intelligent diversion alarm system is reliable and sensitive and can effectively prevent the leakage of high-pressure syringes.
