Description
HYPERTHERMIA:
The therapeutic effects of Hyperthermia on the human body have been well-known since the 19th Century. It is mainly being indicated for inflammatory process, usually accompanied with pain. Methods used made it very difficult to obtain deeply. Controlled and harmless thermal increases and some requires "invasive" techniques.
What is Therma-s:
Therma-S is intended for therapeutic diathermy to produce deep heating without excessive temperature elevation of the skin surface and subcutaneous tissue. Therma-s plus is applied to any part of the human body without pain, muscular contraction or disagreeable sensation of any kind.
The principle of RF Diathermy:
◆The treatment site is placed between the plates of a capacitor and becomes the dielectric.
◆The RF energy is diffused through the part of the body locate between the plate electrodes.
◆The oscillating fields produce distortion of molecules, rotation of dipoles and vibration of ions
◆The movement of the molecules and ions generates heat within the tissues.
◆These actions have been shown to have positive clinical effect on enhancing blood flow.
BIOLOGICAL EFFECT:
1. Increase arterial circulation vasodilatation, giving rise to increased ocygnenation and a decreased acidity of the tissues.
2. Increase venous drainage with greater re-absorption of catabolites and decrease the oedema in areas with inflammatory processed.
3. Increase the permeability of the cellular membrane, allowing better transfer of metabolites through it.
4. Stimulate the immune system and decrease free radicals.
CAP-RES THERMA-S HYPERTHERMIA
Capactitive Electric Transfer(CAP) is a method that allows the RF Electrical current to be transferred “by Capacity”（principle of the electrical capacitor) to the patient’s body via a movealbe external application electrode. This is covered with an insulating film which acts as dielctric and the body acts as a second plate of the capacitor. A return plate closes the circuit.
The Resistive Electrical Transfer(RES), introduced in 1994, is different from the CAP.
The application Electrode is not insulated, allowing the current to be transferred directly to the patient with less dispersion, thus obtaining an increase in temperature at a greater depth.
