Heat effect of the applicators
The evaluation of the heat effect of applicators on the basis of the subjective heat sensation by
the patient is strongly influenced by a number of factors, e. g. the thickness of fat layers,
treatment through clothes or bandages, blood circulation, temperature of the skin, etc.
Therefore, the following subparagraphs generally explain the operation of the applicators used
with the
ULTRATHERM 908i
. The heat effect of the electrodes differs fundamentally between the
inductive and capacitive method of application.
4.4.1
Capacitive method of application
With the capacitive method of application the transformation of energy into heat mainly takes
place in tissues with low blood circulation (e. g. fat, connective tissue). Thus, the greater part of
heat is generated in areas near the surface (upper-skin fat tissue) so that not only the transformed
energy but also the distance between applicator and skin is important for the subjective sensation
of heat.
4.4.2
Inductive method of application
The high frequency magnetic field of a coil applicator generates eddy currents in the tissue.
These currents increase with the electric conductivity of the corresponding tissue region (tissues
with good blood circulation, e. g. muscle tissue and inner organs).
To reach these deeper tissues the coil applicators of the
ULTRATHERM 908i
are provided with
an electrostatic shielding that prevents the technically unavoidable electric field of the coil
applicator from effecting the upper-skin fat tissue and its heating. Therefore, the feeling of heat is
basically delayed and it is recommended to start the treatment with a dosage level below the
desired one and increase then guided by the patients heat sensation in the treated area. The
dosage and treatment time values given in the application table should be observed.
During all the treatment time, the patient must be in contact with the Diplode!
If the patient is excessively heated up, do not change the body-Diplode contact position but
decrease the output power or the patient turns off the
ULTRATHERM 908i
by pulling the
ripcord.
Intermediate checks are recommended. In doing, observe the actual dosage shown on display
(15)
to obtain reproducible results within a treatment series.
An excessive output power (dosage) and missing intermediate inspections by the therapist often
result in mismatching in the practice because the patient often does not switch off the
ULTRATHERM 908i
by means of ripcord and emergency-off switch but changes his/her
