Integrated medium frequency current and electric field exciting equipment

Abstract

Integrated medium frequency current and electric field exciting equipment comprises a single chip microcomputer central control unit, an insulation or contact integrated electrode, a signal generation unit, a power amplification unit and an output switching module. The insulation or contact integrated electrode is formed by a current exciting part and an electric field exciting part, the signal generation unit is connected with the single chip microcomputer central control unit and generates exciting signals of different shapes and frequencies under the control of the single chip microcomputer central control unit, the power amplification unit is connected with the signal generating unit and amplifies the exciting signals, the output switching module is connected with the power amplification unit, enables the amplified exciting signals to be connected to one lead wires under the control of the single chip microcomputer central control unit. According to the integrated medium frequency current and electric field exciting equipment, medium frequency electric field excitation or medium frequency current excitation can be carried out on the cells or the tissue of tumors according to the selection of experimenters, and the two kinds of excitation can also be carried out alternatively to observe synergistic effects.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, relates to experimental research on tumor treatment, and in particular to an integrated medium-frequency current electric field stimulation equipment. Background technique [0002] Since Yoram Palti et al. discovered in 2004 that low-intensity (1-2V / cm), medium-frequency (100-300kHz) alternating electric fields can selectively inhibit tumor cell proliferation, known as tumor treating fields (Tumor Treating Fields, TTF), more and more More institutions are involved in the research of intermediate frequency electric field and intermediate frequency current (frequency 100-300Khz, current size about 50mA) in the field of tumor treatment. Medium-frequency electric field stimulation places non-contact electrodes on both sides of the stimulated tumor cells or tumor tissues. The current mechanism shows that it inhibits the proliferation of tumor cells mainly by interfering with the formation of...

AI Technical Summary

Problems solved by technology

[0004] Although medium-frequency electric field stimulation and medium-frequency current stimulation are similar, the existing mechanism shows that their stimulating effects on tumor tissue are indeed different.

The existing medium-frequency electric field and medium-frequency current tumor treatment experimental equipment is single, which brings great inconvenience to experimental researchers, because many research institutions need to study the tumor stimulating effect of medium-frequency current and medium-frequency electric field at the same time, and may also need to study the effects of the two effects. synergistic effect

According to the current existing scheme, a variety of experimental equipment (intermediate frequency electric field stimulator, signal generator, power amplifier, etc.) will be needed. At the same time, the existing equipment cannot provide some intelligent stimulation modes.
