Double-pulse magneto-sensitive synergy instrument

Abstract

The invention discloses a double-pulse magneto-sensitive synergy instrument. The double-pulse magneto-sensitive synergy instrument comprises a magnetic head and a control circuit. For the magnetic head, a magnetic material is used as a magnetic core, and an excitation coil is utilized to generate a relatively high magnetic field. The control circuit controls a pulse current of the coil arranged in the magnetic head, and the purpose of controlling the strength of the magnetic field and the frequency of the pulse magnetic field is achieved by controlling the magnitude, direction and change frequency of the pulse current. According to the technical scheme of the invention, the problem of residual magnetism is solved by utilization of positive-negative double pulses, the change amount of a magnetic flux is substantially increased, and the continuous adjustability of the change rate of the magnetic field is ensured. In addition, the selection of a unidirectional pulse magnetic field is retained, and flexible selection according to requirements is realized.

Description

technical field [0001] The invention belongs to medical electromagnetic sensitization technology, and more specifically relates to a new double-pulse magnetic field generator to enhance the effect of tumor radiotherapy and chemotherapy by using pulsed magnetic field. Background technique [0002] Tumors are common and frequently occurring diseases that endanger human health, among which malignant tumors, or cancer, are currently one of the most serious diseases that endanger human health. At present, radiotherapy and chemotherapy are still one of the main means of tumor treatment. However, due to the lack of selectivity and pertinence, radiation and chemotherapeutic drugs not only kill cancer cells, but also kill normal cells in the human body during radiotherapy and chemotherapy. Significantly decreased, many patients therefore give up radiotherapy and chemotherapy. In fact, many cancer patients died not from the tumor itself, but from complications caused by radiotherapy...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used pulse magnetic sensitivity synergistic instruments are generally single-pulse magnetic field and unidirectional pulse sequence (continuous pulse) magnetic field. The former generates too much magnetic field strength, while the latter uses unidirectional current, and the strength decreases.

The coil that generates the magnetic field can be an air-core coil, without the problem of residual magnetism, and the magnetic induction intensity is small; it can also use magnetic materials (such as silicon steel, ferrite, etc.) to enhance the magnetic field, but there is a problem of residual magnetism
