单相恒流脉冲神经刺激器的设计

Nerve stimulator with single-phase constant-current pulse

以单片机作为神经刺激器的控制核心,可以很方便地产生各种刺激模式。两级恒流,脉宽监控和浮地,不但保证了高质量恒流刺激脉冲的产生,而且也保证了电气安全。无论使用针型电极或者体表敷贴电极,都能达到超强刺激。

M PU employed as control center,the nerve stimulator can produce different stimul ation modes easily.The high-quality constant-current pulse and the safety of th e patient are ensured through two-steps current stabilizer,pulse width monitor and the float to ground.Both needle electrode and surface electrode can be used to achieve supramaximal stimulation.
