The unit AMD-Iskra-4 (darsonvalization)
Darsonvalization - electrotherapy method, which uses a pulsed alternating current of high frequency,
high voltage and low power.
The method is named after the French physiologist D'Arsonval, who has studied the physiological
effect of high-frequency currents and their proposed use in medical practice.
Biological and therapeutic effects.
During the procedure, local darsonvalization the electrodes are supplied from
the resonator voltage up to 30-40 thousand.
Volts. In the cavity of the electrode there is a glow gas discharge,
in which the electrode begins to glow purple-blue.
Upon application of the electrode to the skin or mucosa creates an original condenser,
one plate of which is the gas in the tube, and the other - the human body.
Between the capacitor plates experience a high frequency electric discharge.
The intensity of the irritant and the discharge will depend on the output power
and the distance from the electrode surface of the body.
At the close contact of the electrode with the skin or mucous membrane there is a "quiet" spark,
which is almost does not cause any irritating effects.
If you zoom out from the electrode surface of the body,
then the intensity of the spark discharge increases and intensifies its irritant effect.
In some cases, due to the concentration of the charge at the
end of the electrode spark discharge can have a cauterizing effect.
Occurs when a local darsonvalization electrical discharge irritates receptors in the skin
and mucous membranes, causing tingling or burning sensation and reflex has
an effect on various organs (kidney, heart, stomach, etc.)
And body systems. Especially intense action local darsonvalization has on the autonomic nervous system.
The thermal effect of local darsonvalization manifested in a very small extent,
as applied current is pulsed nature and low power.
Feeling the heat of light occurs only during vacation abdominal procedures.
Spark discharge destroys the cellular elements of the skin
and causes the appearance of biologically active substances such as histamine.
Local darsonvalization expands the capillaries and arteries-ly, increases the tone of veins,
increases blood circulation in the arteries and veins.
Darsonvalization stimulates the cells of the reticuloendothelial system,
increases tissue metabolism, dramatically improving skin trophism and mucous membranes,
strengthens the processes of regeneration.
Local darsonvalization has clearly expressed analgesic and antipruritic effect due
to the direct influence of the spark charge as sensory nerve endings,
and the autonomic nerves of the skin and mucous membranes.
Some authors point to the surface a bactericidal effect of the spark discharge.
The main indications.
Local darsonvalization shows in violation trophism skin and mucous membranes.
Thus, it is used in cosmetic practice in hair loss and reduced skin turgor,
in the treatment of periodontitis and gingivitis as well as itching of the skin
and mucous membranes, poorly-ating epitelizi wounds, fractures of the skin
and mucous membranes.
The beneficial effects of local darsonvalization arterial and venous circulation is used in
the treatment of Raynaud's disease, obliterating endarteritis initial stages,
as well as varicose skin and hemorrhoidal veins.
In the clinic of nervous diseases darsonvalization used to treat neuralgia and neuritis,
as well as in violation of the sensitivity of the skin (paresthesia, hypoesthesia).
Sometimes this method affect the corresponding reflex zones
(neck area, lumbar region, the heart, etc..)
To obtain a reflex reaction of the internal organs.
So, the heart darsonvalization with nervousness relieves pain associated
with functional spasm of the coronary vessels.
When darsonvalization neck area dilates blood vessels mater, improves blood circulation in the brain, reduces migraine headaches.
Main contraindications:
malignancies, active pulmonary tuberculosis, a condition after the course of radiation therapy
for at least 2 weeks (in action).
Technology and technique of the procedure.
Currently, the medical device industry produces for the local darsonvalization
"Iskra-1", "Iskra-3", "Iskra-4 AMD", "spark-4 AMDg", "Ultraton", "Ultradar".
It is a high-frequency current pulse generators (software kHz) low power.
The individual pulses of high-frequency current is followed by a 50 Hz and have a pause between,
many times greater than the pulse duration.
To improve the high-frequency voltage has a special high-voltage transformer,
which is mounted in a plastic pen holder with slot for inserting the working electrode
Electrodes for local darsonvalization are vacuum glass tubes of different shapes,
of which the exhausted air to a residual pressure of 0.1-0.5 mm Hg. Article ( "Iskra-1")
is either argon gas ( "spark-3" Includes 8-10 electrodes that allow to work on different
areas of the skin and mucous membranes (2 mushroom-shaped, 2 rectal, vaginal, otic, pectinate and gums ).
Depending on the exposure process is carried out in the patient supine or sitting on a wooden couch.
Bare corresponding part of the body, and if it is wet with sweat from the speaker,
it is wiped and dried.
Since moist skin resists the smooth movement of a nurse check the pre-work unit
and vacuum electrode on your hand.
Defective electrode should light pinkish-violet light, and sister must feel on his arm tingling
due to slips sparks.
Upon such verification, the power control knob in the device is set to zero,
and to be exposed to the applied area of the skin electrode.
During the procedure, an electrode smooth longitudinal or circular motion without pressure
move through the body
. Dosage adjustment procedures carried power and duration of the procedure.
During the power control knob routines set to a position that provides an appropriate sense of weak,
medium or strong tingling. After the procedure,
the power control knob is set to zero and then removed from the electrode body.
Depending on the size of the impacted area of skin treatment time ranges
from an average of 5 to 20 minutes.
Procedures are carried out every day or every other day.
During the procedure, it is recommended not to touch the patient,
as this may cause an unpleasant spark discharge.
When abdominal procedures electrode lubricated sterile vaseline and introduced
into a corresponding cavity, and a handle fixed electrode sacks with sand.
When exposed to the gums or mucous membranes of the nose and lubricated with
Vaseline electrodes do not need the skin of the auditory meatus.
After abdominal procedures electrodes disinfected with alcohol.
Electrodes can not boil, as this could lead to a breach of the vacuum and their failure.
Vacuum electrodes can be stored in jars with alcohol, but only when it is immersed in the spirit
of the glass electrode, the metal part must not come into contact with the liquid.
Before the procedure, the electrodes must be thoroughly dried.
Some special techniques darsonvalization. Darsonvalization scalp for the treatment of seborrhea.
Previously removed from the hair pins, hair clips and hair comb.
The procedure is performed using a comb electrode.
The skin of the scalp is not sprinkled with talcum powder.
Electrode is slow combing movements from forehead to nape.
Since the hair during combing electrode has to detach from the surface of the head,
the power regulator is set to a weak feeling of tingling.
Duration of the procedure up to 10 minutes every day or two.
The course of treatment - 10-15 procedures.
Darsonvalization in the treatment of cardiac neurosis.
Lying on the couch sick mushroom electrode without pressure produces a circular motion
on the powdery talc surface of the skin.
Zone of influence - from the collarbone to the costal arch and from the sternum to the anterior axillary line,
excluding the area of the nipple and areola.
Power influence - until you feel weak tingling.
The treatment lasts 8-12 minutes. Procedures are carried out every day or every other day.
The course of treatment - 8-12 procedures.
Rectal darsonvalization in the treatment of hemorrhoids.
Before the procedure, the patient should empty the bowel and wash the
skin with warm water in the crotch area.
The patient is lying on its side with legs bent at the knee and hip joints of the lower
extremities (hips are given to the body), is introduced into the anus to a depth of 4-5 cm greased with
Vaseline sterile rectal electrode.
The handle of the electrode are fixed with sand bags to the electrode lying horizontally
and not pressed on the side walls of the anus.
Power is increased until the patient feeling a light heat.
The duration of procedure is 10-15 minutes. The electrode is removed only after the machine is turned off.
The procedure is performed every day or every other day.
The course of treatment - 12-15 procedures.
Darsonvalization in the treatment of neuralgia of the lateral femoral cutaneous nerve
(Rota disease - Bernhardt). The patient lies on his side.
Mushroom electrode is moved in a circular motion on the outer surface of the femur.
the impact of power - until the tingling of medium intensity
. Duration of the procedure up to 20 minutes. Procedures are carried out every day or every other day.
The course of treatment - 10-15 procedures.
Darsonvalization in the treatment of periodontal disease.
Special gingival electrode is applied to the gums and slowly move it along the alveolar
bone on the vestibular, and then on the lingual surface.
Power influence - until you feel weak tingling.
During the procedure, you should not touch the electrode to the teeth,
as in this case there is a painful spark. The procedure lasts about 6-10 minutes on the gum each jaw.
Procedures are carried out daily, a course of treatment - 15 procedures.
