摘　　要：所设计的植入式刺激器用于治疗功能性胃肠道疾病。该刺激器利用μC/OS-Ⅱ实时操作系统内核来建立稳定高效的软件系统。基于STM32F103芯片的硬件系统完成产生刺激脉冲,采集胃肠道压力信号的任务。刺激器通过无线通信模块与外部控制器进行通信,接收外部控制器的控制命令,并将采集到的压力数据发送给外部存储器进行存储。实验结果证明:样机输出波形正常,可以准确发送所采集的压力信息,电刺激系统设置的参数范围大,可以应用在动物实验中。The designed implantable electrical stimulator is used for treatment of functional gastrointestinal disorders. This stimulator uses μC/OS-Ⅱ real-time kernel to build a stable and high effective software system. The hardware system based on STM32F103 completes tasks including generating stimulus pulses and sampling pressure signals in gastrointestinal tracts. The stimulator communicates with outside controller by wireless communication module, receives control command and sends pressure datas to outsider memorizer for storage. Experimental result shows that the prototype output waveform is normal and sampled pressure information can be transmitted precisely. The scale of parameters set by electrical that stimulator is broad enough for vivo experiments.
