Neurovector Description

          It is evident the importance of alternating currents of medium frequency in electrotherapy . In NEUROVECTOR 2.0 V, these alternating currents have the operating frequency of 2000 Hz, 4000 Hz or 8000 Hz which penetrate deeply into the tissues producing a wide variety of physiological effects. They allow high current densities with small sensory effect on the skin, making it quite pleasant to the patient. The danger of burns under the electrodes is minimal. The so-called interferential current is a technique where two medium frequency alternating currents of different phases or frequencies intersect. The overlap of amplitudes results in new frequency, called "Beat Frequency" or "Frequency Modulation Amplitude (MFA).

We highlight the following features of NEUROVECTOR V 2.0:

– Operation through a touching keypad with information showed in the  crystal LCD.

Interferential estimulation Mode

– Bipolar (pre-modulated) mode – continuous or surge;

– Tetrapolar – Normal or with manual or automatic operation of the vector; 

– Possibility of choosing automatic scanning range of frequency modulated – SWEEP (also known as AMF); 

– Possibility of choosing the carrier frequency of 2000 Hz, 4000 Hz or 8000 Hz;

 – On, Off, Rise and Decay for muscle exercises (so arises); 

– Allows you to choose the time of application, automatically turning off the current emission at the end of the programmed  schedule.


           NEUROVECTOR V 2.0 is a device designed for continuous operation mode. It uses microcontroller technology to ensure the accuracy of the values shown. The accuracy of this operation is in accordance with the provisions of the standards for particular safety equipment for neuromuscular stimulation – NBR IEC 60601-2-10, Clause 50 subclauses 50.1 and 50.2. The output amplitude control continuously monitors the output current intensity from the minimum to the maximum and minimum value does not exceed 2% of the maximum position. The parameters such as waveform output, pulse duration, pulse repetition frequency, amplitude range of output current do not differ by more than 30% mentioned in the following technical description.

           The values of the durations of pulses and  pulse repetition frequency described here were measured at 50% of the maximum amplitude of the output.

           These parameters are for a range of load impedance of 820 Ω to 1200 Ω. The effect of load impedance parameters described is very important. If the appliance is operated outside the range specified load impedance, there may be inaccuracy in the values of the parameters, as well as modification of the waveforms described here.

          Neurovector V 2.0 is a Class II single-phase equipment with Type BF applied part of security and protection.
