体感诱发电位电流刺激器的研制

The development of a current stimulator for the measurement of somatosensory evoked potential

本文介绍一种用于体感诱发电位测量的电流刺激器。该刺激器由微机控制。刺激强度０．１ｍＡ－９９．９ｍＡ可调，步长为０．１ｍＡ，有１２档刺激频率及４档刺激脉冲宽度。文中还给出了性能测试方法及测试结果。

A microprocessor controlled current stimulator used for measuring somatosensory evoked potential is presented in this paper. There are available adjustable stimulus intensity of 0.1-99.9 mA in 0.1mA steps,twelve grades of stimulus frequency,and four grades of pulse width.The test method of its performance and the results are illustJrated.
