Description

technical field [0001] The invention relates to the field of medical consumables, and in particular to a conductive paste and a preparation method thereof. Background technique [0002] Medical conductive paste is mainly filled between the electrode and the skin to increase the test effect by reducing the impedance. In the clinical measurement of bioelectricity (EEG, ECG, EMG), in order to reduce the influence of skin oil and stratum corneum on electrical signals, the conductive paste is filled between the electrodes and the skin, which effectively reduces the distance between the electrodes and the skin. Impedance, to ensure good contact between the electrode and the skin surface, so that the measurement signal is clear, the artifacts are small, and the noise is low, thereby enhancing the test effect. Due to the complex environment of the hospital, after opening the bottle of conductive paste, the doctor will take it repeatedly, which will inevitably lead to contamination ...
