A design of electrophysiological stimulator / 中国医疗器械杂志

ABSTRACT

Electrophysiological stimulator is widely used in study of biological electrical activities. This electrophysiological stimulator is capable of outputting both biphasic and monophasic waveforms with amplitudes within 0V and 30V. The sequence of the biphasic waveforms is alterable and their widths and interval can be respectively arbitrarily modified by the operator. The machine will inform the operator as soon as the charge completes through the indicator and buzzer. The safety of experimental objects is guaranteed by float ground thanks to battery power supply.
