摘要
目的针对现有扩宫棒存在的缺点,设计一种充气式自动扩宫棒。方法采用TMS320F28335作为主控芯片和自适应控制方法,通过采集棒体内气体压力,模数转换后送入控制器,控制器处理后控制电气比例阀,从而使棒体内气体压力满足临床要求。结果成功设计了一款充气式自动扩宫棒。通过对比实验,自动扩宫棒免去了反复插拔钢棒给患者带来的痛苦,并减小了出血过多带来的风险。与传统钢棒相比具有明显优势。结论充气式自动扩宫棒操作方便,能明显改善扩宫对患者造成的痛苦,具有较高的临床应用价值。
Objective Aiming at the shortcomings of existing cervical dilatation rods,an inflatable automatic dilatation rod is designed.Methods The inflatable automatic dilatation rod used TMS320F28335 as the main control chip,and controlled the gas pressure inside the rod using adaptive control method.The pressure was sent to the controller after A/D conversion,and the controller controlled the electric proportional valve to make the gas pressure in the rod meet the clinical requirements.Results An inflatable automatic dilatation rod was successfully designed.Comparative experiments showed that the automatic dilatation rod eliminated the pain the and risk of excessive bleeding caused by repeated insertion and removal of the traditional cervical dilatation rod.Compared with traditional steel rod,automatic dilatation rod had obvious advantages.Conclusion The inflatable automatic dilatation rod is convenient to operate,and can obviously relieve the pain caused by cervical dilatation,which has high clinical application value.
