Disposable Iontophoresis Pads | pH-Buffered Electrodes | TOP-RANK
Medical-grade disposable iontophoresis pads with integrated buffering technology. Maintains skin pH (5.5-7.0) during active medication transport. ISO 13485 and MDSAP compliant.
Product Overview
These disposable pads are the patient-interface for active transdermal drug delivery systems (Iontophoresis). They utilize a low-voltage electrical gradient to drive ionized medication across the stratum corneum. Unlike passive patches, the engineering focus here is on maintaining electrochemical stability to prevent skin irritation caused by the accumulation of hydrogen ($H^+$) or hydroxyl ($OH^-$) ions at the anode and cathode.
Key Features
-
Electrochemical pH Stabilization
During active iontophoresis, water electrolysis at the electrodes can cause extreme pH shifts (acidic at the anode, alkaline at the cathode). Our pads integrate a chemical buffering system within the reservoir layer. This buffer neutralizes excess ions in real-time, keeping the skin-interface pH within the biocompatible range (5.5 - 7.0) for the duration of a 20-minute treatment.
-
Ag/AgCl Polarization Management
Standard carbon electrodes can polarize quickly, leading to an increase in resistance and a decrease in drug delivery efficiency. By utilizing a screen-printed Silver/Silver-Chloride (Ag/AgCl) layer, we maintain a stable voltage-to-current ratio. This allows for precise milliampere-minute (mA-min) dosing, which is critical for clinical protocols involving dexamethasone or lidocaine.
-
High-Saturation Reservoir Integrity
The absorption layer is engineered to hold 1.5cc to 3.0cc of solution without "leakage" or "wicking" at the edges. The high-density non-woven fiber matrix ensures that the drug solution is distributed evenly across the electrode surface, preventing current crowding and localized thermal hot spots.
Applications
Physical Therapy
Localized delivery of anti-inflammatory medications for tendonitis or bursitis.
Dermatology
Treatment of hyperhidrosis via water-based or anticholinergic iontophoresis.
Sports Medicine
Rapid recovery protocols requiring targeted corticosteroid transport.

Testing: Batch-level validation of pH stability, reservoir absorbency, and electrical continuity.
FAQ
Q: Why do chemical burns occur if the buffer is exhausted?
A: If the current continues after the buffer capacity is depleted, the pH of the reservoir will shift rapidly (as low as 2.0 or as high as 12.0). These are chemical burns, not thermal ones. Our buffer is sized for a standard 40-80 mA-min treatment protocol to prevent this failure mode.
Q: How does the Ag/AgCl layer improve delivery accuracy?
A: Ag/AgCl is a non-polarizable electrode. It maintains a near-constant potential at the interface. Carbon-only electrodes require increasing voltage to maintain the same current as they polarize, which can lead to patient discomfort and inconsistent medication dosing.
