YingChi Technology

Shenzhen Yingchi Technology Co. Ltd. is a medical device company that was established in June 2012 that specialises in the development of non-invasive magnetic stimulation systems for depression treatment, clinical examination and research in neurophysiology, neurology, cognitive neuroscience, rehabilitation and psychiatry. These FDA and CE-cleared solutions include the M-series TMS and S-series TMS, find out more details by reading more below!

Transcranial Magnetic Stimulators.

The M-Series TMS

The M-series is implemented with the TMS (transcranial magnetic stimulation) technique, a painless and non-invasive neuromodulation technique that encourages stimulation throughout the skull bone to selectively stimulate specific brain regions. This stimulation occurs with a short magnetic pulse to induce current flow closed to the surface that would encourage brain activity. This product can be applied for both research and clinical application for the department of neurology and rehabilitation (i.e Parkinson’s disease, Motor Neuron disease, MS, cerebral apoplexy and etc.), psychiatry and psychology (i.e depression, PTSD, schizophrenia, anxiety disorder, etc.), and other fields (i.e cognitive neuroscience research, rehabilitation research, brain function research, addiction and drug cessation, etc). This hardware is designed with the paired pulsed transcranial magnetic stimultation (ppTMS) and a PC interaction system. The ppTMS device output two pulses per application within the interval time 0-100ms that is adjustable to the user’s preference. These pulses can output to one coil to stimulate one position or output to two different coils respectively. The PC interaction system stores each patient’s stimulation data and diagnosis reports while supporting the external triggering function (available in various languages). In addition, the system is built with an MEP module, provides an open model for research application and supports the paired stimulation.

  • ISI: 0-100ms, adjustable
  • Multiple stimulation models: single pulsed stimulation rTMS, ppTMS, TBS
  • Equipped with two sets of charge and discharge systems which can treat two patients simultaneously

YingChi-TMS Model & Configuration


The S-Series TMS

This series can be adopted for both clinical and research applications, in particular research into the field of neurology and rehabilitation, and therapeutic application for depression, schizophrenia, PTSD, obsession, anxiety disorders, and more. For research, the S-series TMS can be equipped with TMS-EEG(ERP) synchronous signals acquisition box. The synchronous record of TMS-ERP takes advantage of the high temporal resolution of EEG to track the changes of the neuronal activities evoked by TMS. This technology can record the cortical potential evoked by TMS and the diffusion potential from the stimulation target. Moreover, the series supports the PAS which is an important method to study the cortex plasticity, including long term potentiation (LTP), long term depression(LTD).

S-series TMS Model & Configuration

Paired Associative Stimulation (PAS)

The S-series TMS supports PAS to which refers to a paradigm consisting of slow and repetitive low-frequency median nerve stimulation combined with TMS over the contralateral motor cortex. This protocol has been shown to induce plastic changes of excitability in the human motor cortex. Its principles of design were shaped after associative long-term potentiation (LTP) in experimental animals, a cellular mechanism likely to be relevant for learning and memory. PAS-induced changes of cortical excitability share a number of physiological properties with LTP. In particular, the fact that the sign of PAS-induced changes of the size of amplitudes of the motor evoked potentials (MEPs) depends on the exact interval between the afferent and the magnetic pulse during the intervention.
