1 Introduction
1.1 Intended use
The
SONOSTAT 135
is a classical ultrasound therapy device for constant and pulsed ultrasound. All
applications are to be executed with easy and safety.
The ultrasound therapy device
SONOSTAT 135
generates ultrasound waves by means of the two main
components, the generator and the treatment probe. The resulting effects may be distinguished as follows:
a) Mechanical effects (primary effect)
The ultrasound wave causes a vibration and acceleration of the mass particles in
the exposed tissue (high-frequency vibration massage).
b) Thermal effects (primary effect)
The temperature in the area of the exposed tissue rises locally. The energy flow and temperature in the
tissue being treated is determined by the absorption and reflection of ultrasound. This will vary greatly
according to the tissue involved.
c) Piezoelectric effect (primary effect)
Under alternating mechanical pressure, electrical potentials are induced which increase cell activity,
particularly in bones.
In addition: biological effects (secondary effect)
Due to thermal and mechanical processes, biological effects such as increased membrane permeability
and vascular dilation are achieved. As a consequence, the patient experiences a relief from pain.
Due to its mechanical, thermal, chemical and biological effects, ultrasound can be effectively used for the
treatment of:
•
inflammatory, rheumatic diseases of the muscoloskeletal system
•
traumatic affections such as contusions, distortions or contractures
•
inflammatory diseases of the peripheral nerves (neuritis or neuralgias)
•
peripheral circulatory and inflammatory diseases.
The range of application is extended by pulse mode. Inflammatory processes can also be treated purposeful.
The
SONOSTAT 135
generates the ultrasound frequencies 1 MHz as well as 3 MHz. Basically, as higher
the ultrasound frequency, as lower is the penetration of ultrasound. According to this, 3 MHz is
recommended for treatments of superficial indications.
In addition the
SONOSTAT 135
offers indication programs. By selecting the desired indication, the
appropriate therapy time, ultrasound power, frequency and constant or pulsed ultrasound are selected
automatically.
