1. Product Introduction
Structure and Composition
A disposable ECG electrode typically consists of the following components:
- Conductive sensor: Usually made of silver/silver chloride (Ag/AgCl) or other highly conductive materials to capture body surface electrical signals.
- Conductive gel: Ensures optimal electrical contact between the electrode and skin, reducing signal interference.
- Adhesive backing: Made of non-woven fabric or foam, providing secure skin adhesion.
- Lead connector: Used to connect to ECG monitors or EEG machines.
Features
- Single-use: Prevents cross-contamination and complies with medical hygiene standards.
- High-precision signal acquisition: Ensures accurate ECG, EEG, and other bioelectrical readings.
- Comfortable: Soft materials minimize skin irritation, suitable for prolonged monitoring.
- Convenient: Ready-to-use, no additional cleaning or disinfection required.
Classification
- By application: Chest leads, limb leads, EEG electrodes, etc.
- By patient type: Adult, pediatric, or neonatal (e.g., certain Philips models are designed specifically for infants).
2. Usage Instructions
Preparation
A. Skin cleaning: Use alcohol wipes or mild soap to clean the electrode placement area, removing oils and dead skin for better conductivity.
B. Electrode selection: Choose the appropriate size based on patient age and monitoring needs (e.g., adult or pediatric).
Application Steps
A. Remove protective film: Take out the electrode and peel off the plastic backing.
B. Place on skin: Apply the electrode to the designated position:
- Standard 12-lead ECG: Chest (V1-V6) and limbs (RA, LA, RL, LL).
- EEG monitoring: Follow the international 10-20 system for scalp placement.
3. Secure adhesion: Press gently to ensure full skin contact, avoiding air bubbles or loose edges.
Device Connection
- Plug the lead wires into the corresponding ports on the ECG monitor or amplifier.
- Check signal quality and adjust filtering settings (if needed) to minimize interference.
Post-Use Handling
- After monitoring, remove the electrodes gently to avoid skin irritation.
- Dispose of used electrodes as medical waste-do not reuse.
