The operation of the device must be performed only by trained medical professionals.

1.3 Admission

We recommend that the operator should be trained when using the unit.

1.4 Device description Duodynator

The Duodynator is a microprocessor controlled electrical stimulation device for
electrotherapy. The application makes the device ideal for use in the physiotherapy
department of hospitals and in the modern and well-equipped practice.
The Duodynator is a therapeutic device for the classic electro-therapy with single-
circuit currents, particularly in multi-channel operation, as well as for therapy with
two-dimensional interference currents.
If two middle-frequency electrical circuits of different frequencies, or those which are
phase shifted towards each other, transpose, a new frequency – the interference
frequency – is generated at the intersection point through superpositioning of the
superposed amplitudes. Duodynator uses this two-dimensional interference method.
This allows the desired highest possible low-frequency stimulation from the
immediate area surrounding the electrode to be shifted into deeper regions, since this
is where it is generated.
Apart from the two-dimensional interference currents, Duodynator offers a selection
of single circuit currents and provides a therapy with medium sine waves. This
therapy is absolutely free of d.c. components. There are two channels available The
carrier frequency can be set from 4000 to 10000 Hz in steps of 2000 Hz.
Furthermore, the Duodynator offers the classical Low Frequency currents including
the galvanic current (d.c.). The galvanic current is used to stimulate the circulation in
the area to be treated.
