由于脊柱拉伤,病人的排尿功能丧失,平时不得不在体内保留导尿管排尿.但这种方法经常引起尿路感染和膀胱结石.如果累及肾脏,甚至危及病人生命.电子膀胱刺激器就是为了解决下运动神经元较差的患者的排尿功能而设计的.此刺激器包括发射机和接收器两部分如图1所示.发射机置于人体外部,它所发射的是1兆赫载频的脉冲调制信号.接收器为一无源网络,用医用硅橡胶全部密封,永久性地埋藏在人体内. Due to spinal strain, the patient’s voiding dysfunction, usually have to keep urinary catheters in the body, but this method often causes urinary tract infections and bladder stones, if involved in the kidney, even endanger the lives of patients .Electrical bladder stimulator is to solve Lower urinary motor neurons in patients with poor urinary function design.The stimulator includes a transmitter and a receiver in two parts as shown in Figure 1. The transmitter is placed outside the human body and it emits a 1 MHz carrier frequency pulse Modulation signal.The receiver is a passive network, all sealed with medical silicone rubber, permanently buried in the human body.
