The Dupel system consists of:

A patented device that produces a controlled, direct current stimulus;
A patented active (drug delivery) electrode;
A dispersive electrode;
and lead wires that connect the device and electrodes. The clinician fills the reservoir of the conductive, active electrode with the drug to be administered.

Adavantages:
Dupel device. A microprocessor-controlled, two-channel device, Dupel offers ease-of-use and flexibility in treatment options. Two channels allow the clinician to treat two different sites or use drug solutions of different polarities at the same time. The two can also be used when treating a larger single site. The microprocessor design provides flexibility while easing the demands on the clinician. The clinician sets the dosage and current amplitude, and the device does the rest. The current is automatically ramped up so it is more comfortable for the patient and the device calculates the time needed to deliver the selected dosage. If adjustments are made (for example, the current is lowered or paused), the device will automatically recalculate the time needed to deliver the dosage. Once the treatment is complete, the device beeps and automatically ramps down the current. The device will also alert the user if circumstances exist that impede the delivery program.

Dupel is compact and portable and runs on a single 9 volt alkaline battery. Its durability is backed by a three-year limited warranty.
