Description Neurodyn III
It is a neuromuscular stimulator for transcutaneous FES and TENS currents. Although small, NEURODYN III case has a modern design with front panel that enables the therapist to easily adjust the equipment. This is a transcutaneous neuromuscular stimulator, two channels with adjustable independent intensity , they generate TENS and FES currents . It allows the choice of T (pulse duration) of 25 us 500 us and R (repetition frequency of pulses) of 0.5 Hz and 250 Hz. The selection of these parameters (T and R) is made through a touching keyboard with the information shown in a green 7-segment LCD.
NEURODYN III provides the following modes of operation:
1 – TENS: Normal mode (TENS: conventional, acupuncture, brief and intense).
2 – VIF TENS: TENS with automatic variation of intensity and frequency.
3 – BURST: (TENS modulated pulse trains at 2 Hz).
4 – T ON: time of maximum contraction.
5 – T OFF: resting period of contraction.
6 – FES SYNC: (synchronized FES .)
7 – FES REC: (reciprocal FES ).
8 – FES SYNC VIF: (synchronized FES with VIF).
9 – FES REC VIF: (reciprocal FES with VIF).
PRODUCT FEATURES
NEURODYN III is an equipment designed for continuous operation mode. It uses technology which ensures the accuracy of the values shown. The accuracy of this operation is in accordance with the standards for safety equipment for neuromuscular stimulation – NBR IEC 60601-2-10, Clause 50 / subclauses 50.1 and 50.2. The amplitude control continuously monitors the output current intensity from the minimum to the maximum and minimum and its value does not exceed 2% at 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 load impedance in the range from 820 Ω to 1200 Ω.
The effect of load impedance parameters described is very important. If the equipment is operated outside the load impedance range specified , there may be inaccuracy in the values of the parameters, as well as modification of the waveforms described here.
Neurodyn III is a single-phase equipment with Class II Type BF applied part of security and protection.
