超声膀胱容量测试仪的研制

Development of ultrasonic bladder volume scanner

一种基于单片机的超声膀胱容量测试仪的软硬件设计。系统采用精度较高且易于实现的椭球体积公式算法,并结合膀胱超声回波的具体特点,利用较简洁的超声回波信号处理电路,实现仪器的便携式和小型化。由于具有体积小巧、操作简便及电池供电的特点,所以该仪器非常适合医院门诊、巡诊以及病人在家使用。

Software and hardware design of an ultrasonic bladder volume scanner based on MCU is introduced. The system adopts the formula of ellipsoid volume because it is accurate and easily-realized. The ultrasonic image of a bladder is particular, so the system uses a simpler circuit of ultrasonic echo process to realize a light, small and easily-operated device as well as the portable and miniaturized battery-supply. It is suitable for outpatient service or use at home.
