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.

This device comes with all accessories, an internal rechargeable Nicad battery pack and wall adaptor.

General Specs

  • Weight: 18.5 oz
  • Power Supply: Internal Battery P/N QSE 601 NiCad Battery Pack; External Specified Power Supply: P/N L60071 Medical Grade Power Supply.

  • Tolerance: +/- 1%
  • INF Specs

  • Waveform: Continuous Sinusoidal
  • CH1/CH3 (Carrier) Frequency:
  • 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)
    CH4: Adjustable 4001-4150 Hz
  • Premodulated INF (Using one Channel): A mixed Interferential Beat Frequency will be produced only out of CH 1 and/or CH 3.
  • Modes: Constant Stimulation Alternating Stimulation Cycled Stimulation
  • Constant: Beat Frequency is adjustable from 1-150 Hz
  • Sweep 1: Beat Frequency Modulates from 1-10 Hz and back over 12 seconds (6 second increase, 6 second decrease)
  • Sweep 2: Beat Frequency Modulates from 80-150 Hz and back over 16 seconds (8 second increase, 8 second decrease)
  • Sweep 3: Beat Frequency Modulates from 1-150 Hz and back over 20 seconds (10 second increase, 10 second decrease.
  • Intensity: 0-78 milliamps peak to peak
  • Output Voltage: 0-39 Volts peak to peak
  • NMS Specs

  • Waveform: Symmetrical, biphasic, square Asymmetrical, biphasic, square
  • Pulse Rate: Adjustable 1-120 Hz peak to peak
  • Pulse Width: Adjustable 50-400 uS
  • On Ramp: 0-10 seconds
  • On Time: 0-99 seconds
  • Off Ramp: 0-10 seconds
  • Off Time: 0-99 seconds
  • Modes: Constant: Use the Constant Mode or a Pulse Rate greater than 60 Hz. for the relaxation of muscle spasms only. Use of continuous stimulation and/or rates above the normal physiological range (e.g., greater than 60 Hz) could lead to rapid onset of muscle fatigue, making the device less effective in producing repeated forceful muscle contractions.
