Description

Ring-shaped resonant cavity device for knee health care

Technical Field

Background

The ultrashort wave therapy is a method of applying ultrahigh frequency alternating current with the wavelength of 10-1 m to act on a human body to achieve the purpose of treatment, and is called ultrashort wave therapy. The capacitance electrode therapy or the inductance therapy is adopted in the common therapy, and the capacitance field mainly has the function of the ultrahigh frequency electric field, so that the ultrahigh frequency electric field therapy is more applied.

As the human body is a composite tissue with a conductor and a dielectric medium, a conduction current and a displacement current are formed in the human body simultaneously under the action of ultrashort waves. Because the frequency is higher and the resistance of the dielectric medium is smaller and smaller, the displacement current component is dominant when the ultra-short wave therapy is formed, and the heat generation caused by the dielectric loss is the main factor. However, at very high frequencies, the dipole will not rotate as much or will rotate very little, resulting in a reduction in dielectric loss and thus in heat generation. This indicates that the proportional relationship of heat production increasing with increasing frequency is only applicable to oscillation frequencies within a certain range. The displacement current generates heat to overcome the medium resistance, the size of the medium loss is closely related to the dielectric constant of the tissue, and the difference of the dielectric constants of various tissues in the human body is small, so that the heat distribution generated under the action of ultrashort waves is uniform.

However, in some conventional inductance therapy apparatuses, when the structural arrangement is not perfect, the frequency waves of radiation are easy to fluctuate, so that the effect of treatment on a human body is unstable, harmful radiation can be generated, unnecessary damage to the human body and the surrounding environment can be caused, and the power consumption and the cost of the whole apparatus can be increased.
