Embodiment

[0029] Adopt the coil of multi-strand oxygen-free thin copper wire of the present invention, the wire diameter of oxygen-free fine copper wire is 0.1mm, the twisted copper wire of 1400 strands is as a wire, and number of turns is 16-18 turns, and resistance is 7~8 milliohms, the cross-sectional area is 10.99 square millimeters, and the surface (perimeter) of the wire is 440mm. Start the magnetic shock therapy device, work at 100Hz, 100% stimulation intensity for 10 seconds, the coil temperature is only 7°C higher than the ambient temperature, and in the case of continuous cooling of the coil water circulation, after a 2-minute interval and then stimulate for 10 seconds, the coil can maintain The temperature shall not exceed the ambient temperature by 8°C.

[0030] While using the coil in the prior art, the diameter of the wire is 2.5 mm, the number of turns is 18, the resistance is 17 milliohms, the cross-sectional area is 9.6 square millimeters, and the surface area (circumfe...

Abstract

The invention discloses a stimulation coil of a magnetic shock therapy device. Firstly, specifically for application characteristics of the magnetic shock therapy device, the coil is designed completely, multi-strand oxygen-free fine copper wires are utilized, the effective conductive area is increased, coil and cable impedance and heat loss are reduced, coil heating is reduced, efficiency is improved, a Teflon tube is wrapped inside the wires of the stimulation coil, the heat radiation fluid is isolated from the wires, and the stimulation coil is easy for safe liquid cooling. The stimulationcoil is advantaged in that the cap-shaped coil fitting the shape of a human head is utilized, the stimulated head is wrapped by magnetic lines generated through magnetic stimulation, and the distancebetween the coil and the scalp is minimized; a magnetic material with high magnetic permeability, such as a silicon steel sheet, an amorphous material, high-conducting ferrite, etc., is embedded or covers around the stimulation coil, when the inductance of the stimulation coil is the same, the high magnetic permeability material is increased, the number of stimulation coil turns can be reduced, the length of the stimulation coil and copper loss of the wires are reduced, and the surrounding magnetic field can be made to return back to the head more along the magnetic permeability material to enter the cerebral cortex of the stimulated site.

Description

technical field [0001] The patent of the invention belongs to the technical field of physical therapy for neuropsychiatric diseases, in particular a coil on a therapeutic device capable of inducing shock by high-intensity and high-frequency magnetic stimulation on the cerebral cortex. Background technique [0002] The method of stimulating the brain to induce general muscle twitches and loss of consciousness to produce shock has proven to be an effective treatment for a variety of neuropsychiatric disorders. [0003] At present, brain stimulation technology is a new technology in the field of brain science to study and treat brain diseases and modulate brain functions. Traditional electric shock is also called electric convulsions, and electric convulsive therapy (ECT) is a method of using electric current to strongly stimulate the brain to induce shock to treat mental diseases. It has been widely used in psychiatry for more than 80 years. ECT uses alternating current to st...
