Main technical indicators of disposable electrocardiogram electrodes
Appearance: should be neat, clean, and free of foreign objects; The conductive paste has no peeling or drying phenomenon; The appearance of electrode metal parts should be smooth, flat, without oxidation or rust.
Size: Tolerance ± 1.0mm.
Electrical Performance
AC impedance: At least 12 pairs of electrode pairs connected by adhesive, at 10Hz and not exceeding 100 μ Under the applied current of A (peak to peak), the average impedance value should not exceed 2k Ω. The impedance of each individual adhesive connected electrode pair should not exceed 3k Ω.
DC offset voltage: After a stable period of 1 minute, the offset voltage of a pair of adhesive connected electrodes should not exceed 100mV.
Composite imbalance instability and internal noise: The voltage generated by a pair of adhesive connected electrode pairs in the frequency band of 0.15Hz to 100Hz (first-order frequency response) after a 1-minute stability period should not exceed 150 within the following 5 minutes μ V (peak to peak).
Defibrillation overload recovery: Charge to 10% of 200V μ F capacitor is discharged through a circuit connected in series with an electrode pair and a resistance of 100 Ω. In the 5th second after the capacitor starts discharging, the absolute value of the polarization electromotive force of the electrode pair connected by the adhesive does not exceed 100mV; Within the following 30 seconds, the rate of change of the remaining polarization electromotive force shall not exceed ± 1mV/s. After conducting the above experiment according to this requirement, the 10Hz AC impedance of the electrode pair should not exceed 3k Ω.
Bias current tolerance: Apply 200nA DC current to the electrode pairs connected to the adhesive for 8 hours, and observe that the voltage change at both ends of the electrode pairs does not exceed 100mV throughout the entire duration.
