Construction & Materials

 

Conductive Element:

Low-impedance tin foil, carbon film, or silver-silver chloride (Ag/AgCl) layer ensuring uniform current distribution across the treatment area.

01

Adhesive Hydrogel:

Proprietary biocompatible hydrogel formulated for balanced skin adhesion, minimal residue upon removal, and stable moisture retention across extended shelf lives.

02

Backing Substrate:

Non-woven fabric, breathable PE foam, or water-resistant polyurethane (PU) film rated for tear resistance and fluid barrier protection.

03

Lead Wire & Connector:

Copper-alloy core lead wire with medical-grade PVC or TPU insulation, terminated with snap connectors (3.5mm/4mm), pin connectors, or specialized plug-in blocks.

04

Release Liner:

Siliconized PET release film protecting the hydrogel layer until immediate clinical deployment.

Pediatric Defibrillator Electrode Pads

 

Functional Performance

AC Impedance: Less than or equal to 200 ohm at 10 Hz (exceeds standard requirements for defibrillation and monitoring).


DC Offset Voltage: Less than or equal to 1 mV to prevent baseline drift in monitoring applications.


Combined Defibrillation/Recovery: Residual potential less than or equal to 10 mV within 5 seconds post-shock discharge.


Adhesion Stability: Maintains reliable skin contact force between 1.0 N/25mm and 3.5 N/25mm on dry and slightly moist skin.


Shelf Life: 24-month stability verified through accelerated aging tests at 50 degrees C and real-time aging at 25 degrees C / 60 percent RH.

 

Key Features

Optimized Current Distribution: Uniform conductive backing minimizes current hotspots, reducing the risk of localized skin burns during high-energy pulses.


Durable Lead Integration: Ultrasonic welding secures lead wires to the conductive element, withstanding tensile pull forces exceeding 50 N.

Hypoallergenic Formulations:

Latex-free hydrogel compositions tested for primary skin irritation, sensitization, and cytotoxicity.

Pre-gelled & Ready-to-Use:

Eliminates gel application steps in high-stress clinical or emergency workflows.

Temperature Adaptability:

Retains functional tackiness and impedance stability in storage environments ranging from 0 degrees C to 50 degrees C.

FAQ

 

 

Q: What is the typical shelf life of your electrode pads, and how should they be stored?

A: Standard shelf life is 24 months from the date of manufacture when stored in unopened foil pouches at temperatures between 5 degrees C and 30 degrees C and relative humidity below 75 percent. Storage outside these parameters accelerates hydrogel moisture loss and degrades adhesion.

Q: Can you match the proprietary connector plug of a specific device model?

A: Yes. The engineering team develops custom injection molds for specialized plug-in blocks, matching physical dimensions, pin configurations, and electrical resistance parameters of major device platforms.

Q: What biocompatibility testing data is provided to support regulatory filings?

A: Complete biological evaluation reports covering cytotoxicity, skin sensitization, and irritation testing are provided to support technical documentation dossiers.

Q: What is the minimum order quantity (MOQ) for custom OEM private-label packaging?

A: MOQs vary by configuration: standard unprinted bulk packaging starts at 5,000 pairs, while custom foil pouch printing and specialized connector assemblies typically require a minimum of 10,000 to 20,000 pairs per production run.

Q: How is hydrogel dry-out prevented during transport and long-term storage?

A: Pads are sealed in multi-layer aluminum-foil pouches with high moisture-vapor barrier properties (MVTR less than 0.5 g/sq.m/24h), combined with siliconized release liners that prevent air gaps over the conductive hydrogel surface.

Q: What quality control records accompany each shipment?

A: Each outgoing shipment includes a Certificate of Analysis detailing lot-specific electrical impedance values, peel adhesion test results, sterility test confirmation, and identification verification logs.
