Problems solved by technology

In fact, if the number of turns is large, the inductance of the coil will also be greatly increased, which will cause problems such as high impedance and difficult current increase, high resonance voltage and unnecessary electric field, small resonant capacitor capacity, easy detuning, and increased coil loss.

Embodiment approach

[0040] Figure 11 is an implementation of this technology: the radiator only draws a schematic side view with a shell, adopts the structure in Figure 1, uses two pole plates 201 instead, the diameter of the wire loop is 130mm, and the working frequency is 27.12MHz. A 27.12MHz power source 22 with appropriate output power is connected to the radiator through a cable, and the radiation surface of the radiator acts on an appropriate part of the human body to perform treatment.

[0041] Figure 12 is a treatment device using dual radiators: one can output two high-frequency power sources with opposite phases and the same frequency and power, and two magnetic field radiators are connected through cables to act on appropriate parts of the human body for treatment.

Abstract

A high frequency magnetic field treatment device comprises high-frequency source and high frequency magnetic field radiator. High frequency magnetic field radiator comprises a parallel-plate capacitor, a group of radiant coil with both ends respectively fixed at two sets of pole plates of capacitor and tuned at high working frequency. Coil can be single line loop or multiple same wire loops parallel connected by capacitor plate through several coils. As the coil inductance of radiator is small, it can generate high efficient large caliber high frequency magnetic field used for diathermic heating treatment including tumor heat treatment.

Description

Technical field [0001] The high-frequency magnetic field treatment device involved in the present invention belongs to medical high-frequency treatment equipment. It includes a high-frequency power source and a magnetic field radiator that converts high-frequency current into a high-frequency magnetic field that acts on the human body. Background technique [0002] The high frequency involved in the present invention mainly refers to short-wave and ultra-short-wave frequency bands, the frequency ranges from several MHz to hundreds of MHz, and the wavelength of electromagnetic waves in this range ranges from 1 meter to tens of meters, which covers the 6.78MHz, 13.56MHz, 27.12MHz, 40.68MHz and other frequency bands. According to the theory of electromagnetic field, the space where the distance from the radiation source is less than λ / 2π (λ is the wavelength) belongs to the near-field range. When the radiator is an electric dipole, a high-frequency electric field is generated...
