简介：DS5隔离式双极恒定电流刺激器允许计算机控制刺激的幅度和时间参数，最大恒定电流输出为±50mA。它的设计初衷是通过促进半自动化的神经兴奋性测试来加快和加强人类周围神经的诊断。然而，它在临床神经生理学研究的更广泛方面也有作用，包括心理学、前庭系统和痛觉测试。 根据欧洲医疗器械条例，DS5隔离式双极恒定电流刺激器是有CE标志的医疗设备。

The DS5 Isolated Bipolar Constant Current Stimulator allows computer control of stimulus amplitude and timing parameters and has a maximum constant current output of ±50mA. It was originally designed to speed up and enhance human peripheral nerve diagnostics by facilitating semi-automated nerve excitability tests. However, it also has roles in wider aspects of clinical neurophysiology research, including psychological, vestibular system and nociceptive testing.  The DS5 Isolated Bipolar Constant Current Stimulator is a CE marked medical device under the European Medical Device Regulation.

The DS5 is controlled by an analogue voltage input or “command” signal which it translates into an isolated constant current stimulus (up to ±50mA), precisely replicating the shape of the input waveform. As a result the DS5 should be of interest to anyone wishing to control surface electrical stimulation protocols via software/hardware combinations capable of producing a suitable command voltage waveform e.g semi-automated pain research or sensory threshold testing. The DS5 has also been employed for galvanic vestibular stimulation (GVS) and transcranial AC stimulation (tACS) protocols.
