Product Description
JY-2420 Digital EEG Equipment is a multifunctional instrument that gathers EEG, brain mapping and EEG wardship function. Clinical medicine, electronic engineering and computer technology are fitted together in it. Its theory of operation is using electrode to record the brain wave signal from human scalp, then it use computer analysis and imaging technique to take order with the recorded brain wave signal to form brain waveform. Furthermore, this device can draw 3D images of the brain electrical activity. The 3D images can quantitative and oriented reflect the changes of the brain function and its range, location and the degree of the pathological changes. It provides objective and accurate foundation for the diagnoses and therapy of the brain disease. With the function on the pathology diagnosis and functionality diagnosis, it reinforces the insufficiency of the CT and MRI. It saves case history in computers and records EEG signal without pencil, so it economizes the prime cost and takes convenient reexamination for the patients. This device can also be added two ECG leads and one breathing lead (optional).
