A low-frequency broadband magnetic field therapeutic apparatus for tumor treatment and its application method

Abstract

The invention relates to a magnetic field therapeutic device with a low frequency band and a high frequency range for treating tumors and an application method thereof. The magnetic field therapeuticdevice is mainly applied to the field of medical treatment. According to the magnetic field therapeutic device, an upper computer is connected with an Helmholtz coil set through a main control unit, amulti-channel broadband signal generating unit, a signal conditioning unit and a power amplifying unit, the main control unit is connected with the signal conditioning unit and the power amplifying unit separately, a magnetic field measuring unit and a temperature feedback unit are connected with the upper computer separately, and the magnetic field measuring unit is formed by connecting a PID feedback adjusting unit and the main control unit. The frequency range of the magnetic field therapeutic device covers a low frequency band of 0.1 HZ-300 Hz, operation is convenient, the direction and magnitude of the magnetic field can be controlled, and when the magnetic field therapeutic device is applied, it is unnecessary to study the optimal magnetic field inhibition frequency of different tumors in advance, so that time is saved, a bad therapeutic effect caused by the specificity of the magnetic field is avoided, the efficiency is improved, the universality of a magnetic field therapeuticmethod applied to different tumors is improved, and the magnetic field therapeutic device can have the obvious inhibition effect on the tumors.

Description

technical field [0001] The invention relates to the field of magnetic field therapeutic apparatus, in particular to a low-frequency broadband magnetic field therapeutic apparatus for tumor treatment and an application method thereof. Background technique [0002] Tumor is a neoplasm formed by the body under the action of various tumorigenic factors, and the cells of local tissues lose their normal regulation of their growth at the gene level, resulting in abnormal proliferation. It is one of the most serious diseases endangering human health at present. Existing tumor treatment methods mainly include chemotherapy and radiation therapy, the curative effect is not satisfactory, and the human body function is greatly damaged. Therefore, it is necessary to study a simpler and more effective new green therapy. Using the biological effects of magnetic fields to treat tumors is a feasible development direction of these new therapies. The magnetic field can be divided into a stabl...

Problems solved by technology

[0007] The above technologies have proposed alternating magnetic field or / and constant magnetic field treatment devices for in vivo tumor treatment or in vitro tumor cell experiments. The treatment of different tumors is frequency-dependent, and different tumors cannot use a single frequency to achieve the best therapeutic effect. In order to improve the universality of magnetic field in the treatment of different tumor cells
