OEM Multifunction Defibrillation Pads | AED & Clinical | TOP-RANK
B2B multifunction defibrillation pads for AEDs and manual monitors. Engineered with gradient Ag/AgCl traces and dielectric PE foam to safely disperse 360J energy vectors without thermal arcing.
Product Overview
These multifunction pads are critical transdermal hardware interfaces designed for external defibrillation, non-invasive pacing, synchronized cardioversion, and continuous ECG monitoring. Unlike standard TENS pads that handle micro-ampere currents, this substrate must transmit massive high-voltage, high-joule shock vectors (up to 360 Joules) into the myocardium within milliseconds. The engineering objective is to drop the thoracic impedance instantly while maintaining strict electrical isolation to protect the operating clinician. We supply these consumable blanks and assembled interfaces to AED manufacturers, hospital procurement networks, and EMS distributors.
Key Features
-
Ag/AgCl Edge-Effect Mitigation
When 360 Joules of energy enters a standard conductive plane, the electrical current naturally crowds around the extreme perimeter of the metal surface (the edge effect). This localized high current density instantly causes third-degree thermal burns on the patient's skin. The Ag/AgCl matrix on this substrate is printed using a calculated gradient pattern. This geometric configuration forces the high-voltage vector to distribute uniformly from the center out to the edges, maintaining a mathematically flat current density across the entire active footprint during the millisecond discharge.
-
Diaphoretic Adhesion & Air-Gap Displacement
Patients in sudden cardiac arrest (SCA) frequently present with extreme diaphoresis (profuse sweating) and dense chest hair. Standard hydrogels slip off wet skin or ride above the hair, creating microscopic air gaps. High-voltage electricity jumping across an air gap generates an arc plasma, burning the tissue without reaching the heart. The internal hydrogel is engineered with a high-tack elastomeric structure that physically forces aside ambient moisture. The high flow-weight of the gel sinks through hair follicles to establish a 100% continuous fluid bridge, dropping thoracic impedance instantly.

5kV Dielectric Backing Isolation
During a code response, paramedics routinely perform chest compressions immediately after a shock is delivered. If the pad backing conducts any residual electricity, the clinician absorbs the stray voltage. Spunlace or porous backings completely fail under these high-tension loads. The substrate utilizes a specific 1.0mm closed-cell polyethylene (PE) foam. This continuous polymer sheet acts as a structural dielectric barrier, mathematically blocking upward voltage bleeds exceeding 5,000 Volts and strictly routing the energy vector downward into the patient.
Applications
Public Access Defibrillation (AEDs)
Extended shelf-life consumables designed for automated external hardware in transit stations and corporate campuses.
Pre-Hospital EMS
Robust leads and heavy-duty adhesion to withstand the kinetic movement of ambulance transport and CPR interference.
ICU & OR Cardioversion
Sustained skin coupling for continuous transcutaneous pacing and synchronized shock delivery.
OEM & Private Label
-
Terminal Connector Matching : We mold custom Anderson-style heavy-duty connectors, exposed pins, and specific keyed sockets to physically interface with legacy OEM hardware from major clinical brands (e.g., Zoll, Philips, Physio-Control compatible blanks).
-
MVTR Barrier Pouching : Defibrillation hydrogels contain critical water volumes. The pads are vacuum-sealed in heavy-gauge AL/PE (Aluminum/Polyethylene) foil pouches engineered to severely restrict Moisture Vapor Transmission Rates (MVTR). This ensures the gel does not desiccate during a 24-month to 36-month standby lifespan.
Certifications
-
Regulatory: Product technical files and impedance data support B2B clients in compiling regulatory submissions for high-risk Class IIb/Class III devices.
-
Systems: Printing, lamination, and automated pouching execute strictly within audited ISO 13485:2016 quality management frameworks.
FAQ
Q: Why do defibrillation pads have a strict expiration date if they are never opened?
A: Foil pouches slow down evaporation, but they do not stop it entirely. Over 24 to 36 months, the water inside the hydrogel gradually escapes as vapor. As the water volume drops, the chloride salts crystallize, and the electrical impedance spikes. Attempting to pass 360J through a dried, expired pad will cause a massive resistance block, failing to defibrillate the heart and severely burning the skin.
Q: Can a paramedic remove the pad from the patient's chest and reposition it if placed incorrectly?
A: No. Defibrillation hydrogel relies on a one-time high-tack polymer deformation to displace air and grip the skin. Peeling the pad off physically ruptures the polymer chains and introduces severe air gaps into the gel matrix. Re-applying the same pad ruins the continuous conductive bridge, risking fatal thermal arcing during discharge.
