Continuously working magnetic stimulation device and method

Abstract

The invention discloses a continuously working magnetic stimulation device and method. The device comprises a magnetic stimulation coil formed by winding a hollow wire and a refrigerant circulation unit; a low-temperature refrigerant preparation flows at the hollow part of the wire, and the low-temperature refrigerant preparation flows in the hollow part of the wire to take away Joule heat generated during working of the magnetic stimulation coil; and the refrigerant circulation unit is used to circulate the low-temperature refrigerant preparation to absorb the Joule heat absorbed by the low-temperature refrigerant preparation from the magnetic stimulation coil, so that the Joule heat generated during the working of the magnetic stimulation coil is absorbed circularly to ensure that the magnetic stimulation coil can work continuously. The device realizes the integration of equipment, does not need to immerse the stimulation coil in cold oil, does not increase the volume of the equipment, and easily realizes flexible movement of the stimulation coil; and compared with a traditional air cooling method, the method provided by the invention has the following advantages: the refrigerantis in full contact with a heated copper wire from the interior, so that the method has a good cooling effect and no noise, and does not increase the discomfort of a stimulated object.

Description

technical field [0001] The present invention relates to the technical field of magnetic stimulation devices, and more particularly, to a continuously working magnetic stimulation device and method. Background technique [0002] Repetitively Transcranial Magnetic Stimulation (rTMS) is a new type of non-invasive biostimulation technology. The stimulating coil is usually placed above the skull with the focus point facing the target area. The alternating current fed into the stimulation coil at a certain repetition frequency generates an induced magnetic field in the surrounding space, which induces an induced electric field in the brain and changes the membrane potential of nerve cells, playing a role in neuroregulation. [0003] Due to the complex structure of the brain, the intracranial non-isotropic homogeneous medium and the low magnetic permeability and electrical conductivity, the induced electric field decays rapidly in the intracranial, and the lesions of mental diseas...
