Electrode depolarization device

Abstract

The invention discloses an electrode depolarization device, the technical problem needs to be solved is to carry out the depolarization processing to the electrode which has the polarization phenomenon. The electrode depolarization device of the invention is provided with a DC power supply and an electrolytic cell, the interior of the electrolytic cell is filled with electrolyte, a positive electrode of the DC power supply is connected with an electrode lead adapter device, the electrode to be subject to the depolarization processing which is connected with the electrode lead adapter device and a cathode which is connected with a negative electrode of the DC power supply are immersed in the electrolyte. Compared with the prior art, the connection structure of the electrode to be subject to the depolarization processing which is connected with the electrode lead adapter device and the cathode which is connected with the negative electrode of the DC power supply is immersed in the electrolyte, so the depolarization processing of an electroencephalogram silver or sliver-silver chloride electrode which has the polarization phenomenon can be carried out, thereby improving the measurement quality of the electroencephalogram and the electrocardiogram and improving the diagnosis accuracy of the doctors on epilepsy, brain trauma, encephalitis, cerebrovascular diseases, intracranial space occupying lesions, heart diseases, and so on.

Description

Electrode Depolarization Device technical field The invention relates to a medical device, in particular to a maintenance device for electroencephalogram, electrocardiogram, reference electrode and other equipment. Background technique Electrodes such as EEG are used to collect EEG signals and are usually made of metal materials with good electrical conductivity. However, when the metal material continues to pass through a direct current, charge accumulation occurs on the surface of the metal electrode due to an electrochemical reaction, resulting in an increase in time- and frequency-dependent resistance. Due to the presence of charge and polarity on the electrode surface, a direct current effect is generated, which produces a large baseline slow drift artifact after amplification. Therefore, this kind of polar metal material cannot be used for collecting EEG signals. Because silver has no obvious polarization phenomenon, it is usually used as the electrode material of ...

AI Technical Summary

Problems solved by technology

Therefore, this kind of polar metal material cannot be used to collect EEG signals.

Because silver has no obvious polarization phenomenon, it is usually used as the electrode material of EEG, but as the use time increases, the polarization phenomenon of silver will increase, which will also affect the quality of signal acquisition such as EEG.
