Quartet Four-Channel Combination Interferential and Muscle Stimulator

Quartet builds upon the exacting engineering utilized in Duet and Duet+ to deliver very precise and repeatable Interferential and Muscle Stimulation therapy across up to four therapy. Quartet adds 8 additional therapies – 2 Russian Muscle Stimulation protocols and 6 Sequential Stimulation protocols.

Quartet’s Quad Boost electronic circuitry ensures accurate therapeutic output up to the specified maximum of 25V (50 milliAmps/Peak). The sophisticated, up to date digital circuitry including Texas Instruments Ultra Low Power microprocessors, allows Quartet to deliver nearly two hours of 4 channel effective stimulation at repeatable, precise parameters on a single battery charge using the included EAZE™ NiMH rechargeable batteries.

Patient safety, comfort and convenience features are engineered into Quartet to improve patient compliance and ensure that Duet provides optimal, safe patient care.

FEATURES:

Digital Patient Watchdog™ provides constant software surveillance of Quartet’s circuitry to maintain energy at patient-safe levels

Clinician-set Therapy Lockout - allows patient therapy to start with just “one-touch”, prevents patient from using other therapy protocols

Clinician-set Maximum Amplitude Lock - limits maximum treatment stimulation amplitude

Visible Muscle Stimulation Contraction Phase Indicator - identifies contraction or relaxation phase of therapy Multi-lingual (English, French, Spanish) – reassures, comforts and increases patient understanding and improves usage compliance

Compliance Meter – accurate recording therapy sessions and time

Pause and Resume – lets the patient deal with interruptions or reposition the electrodes

EAZE™ Safety Patient Lead Wire Assembly – IEC 60601-1-2 compliant and tangle-free
