摘要
目的 设计一种无线低能耗夜间勃起信号传感器替代有线传输传感器,减小穿戴设备体积,以提升临床使用者的穿戴体验.方法 通过设置传感器佩戴标识和佩戴检测程序提升佩戴舒适度和监测初始值的一致性.通过柔性拉伸传感器和柔性压力感器组成多功能传感器,采集阴茎变化数据.利用蓝牙模块将数据传输到个人电脑(PC)端,通过上位机软件用最小二乘法5次多项式进行曲线拟合,最终根据电容-时间和压力-时间的关系,得到夜间勃起曲线.结果 通过模拟实验,发现传感器信号可以顺利传输至PC端,且将压力和周径的变化在软件上实时显示出来.结论 本项研究实现了无线状态下勃起状态监测,完成了信息收集模块与信息处理模块的分体设计,进一步助力夜间阴茎膨大试验(NPT)技术在外科围手术期实践中的应用.
Abstract
Objective To design a wireless low-energy nocturnal erectile signal sensor which can replace the wired transmission sensor and reduce the size of the wearable device,aming to improve the wearable experience of clinical users.Methods The consistency of wearing comfort and monitoring initial value was improved by setting the sensor wearing identifier and wearing detection program.A multi-functional sensor was composed of a flexible tension sensor and a flexible pressure sensor to collect the data of penis change.A bluetooth module was used to transmit the data to the personal computer(PC),then quintic polynomial curve fitting was performed by the method of least squares using the software on the host PC,and finally according to the capacitance-time and pressure-time relationships,a nocturnal erection curve was obtained.Results Through the simulation experiment,the sensor signal was successfully transmitted to the PC,and the software displayed the change of pressure and circumference in real time.Conclusion This study has realized erectile monitoring wirelessly,and separated the information acquisition module and the information processing module,which further facilitates the application of nocturnal penile tumescence test(NPT)technology in perioperative surgery.
