摘　　要：针对尿失禁患者无法在生活中感知膀胱状态的问题,设计了基于A型超声的膀胱尿量监测预警系统。该系统使用二维超声矩阵,采用最小二乘法拟合椭球方程进行尿量估计。终端设备基于STM32采集超声回波数据,通过WIFI模块将数据传输到服务器。服务器处理回波数据来估计和保存尿量信息,并将尿量信息发送到用户APP和终端设备进行显示和报警,降低了终端设备的复杂性。通过实验证明了系统的有效性,满足便携式设计需求。Aiming at the problem that patients with urinary incontinence cannot perceive the bladder state in their lives,a bladder urine volume detection and early warning system based on A-mode ultrasound was designed.The system uses an ellipsoid fitting method to estimate the bladder volume based on a two-dimensional array ultraso-nic transducer.The terminal device collects ultrasonic echo data based on STM32,and exchanged data with server through WIFI communication module.The server processes the echo data to estimate and save the urine volume information,and sends the information to the user APP and terminal device for display and alarm,reducing the complexity of the terminal device.The accuracy of bladder volume detection was verified experimentally.
