Overview

BioMedical Life Systems, is proud to introduce it’s new generation in Electro-Therapy Devices, the QuadStar® Elite four channel (up to 8 electrodes) TENS, NMS, High-Volt and Interferential stimulator in one portable unit.

It’s compact size and user friendly programming features make the QuadStar® Elite’s design unique among Electro-Therapy Devices. The device has an easy to read LCD screen and a digital keypad. Simple to understand instructions guide the user through nine pre-programmed protocols and four types of waveforms; Symmetrical Biphasic Square Wave; Asymmetrical Biphasic Square Wave; Sine Wave; and Monophasic High-Volt, Twin Peak. The user can sequence two or more modalities for complete treatment.

The device has a patient lock system that, when activated prevents the patient from changing any of the set parameters. When the Patient Lock Systems is turned off, a patient compliance meter is displayed showing how long the device was used. A timer allows the patient to use the device for a specified period of time.

The device comes ready to use, with all accessories, and is run by a rechargeable battery pack (included) or Wall Adaptor.

CH1/CH3 (Carrier) Frequency:
 4000 Hz
CH2/CH4 Frequency:
 4001-4150 Hz adjustable
Beat Frequency:
 1-150 Hz
  • CH1/CH2 are an Interferential Pair
  • CH1: Fixed Frequency (4000 Hz)
  • CH2: Adjustable 4001-4150 Hz
  • CH3/CH4 are an Interferential Pair
  • CH3: Fixed Frequency (4000 Hz)

Neuromuscular Specifications
Waveform:
 Symmetrical, biphasic, square Asymmetrical, biphasic, square
Pulse Rate:
 Adjustable 1-120 Hz peak to peak
Pulse Width:
 Adjustable 50-400 µS
On Ramp:
