True and false pulse magnetic stimulation therapeutic apparatus

Abstract

The invention provides a true and false pulse magnetic stimulation therapeutic apparatus. The positive electrode of an energy storage element is electrically connected with the positive electrode of a first electronic switch and the negative electrode of a second electronic switch in a first electronic switch group; the negative electrode of the first electronic switch and the positive electrode of the second electronic switch are electrically connected with a true magnetic stimulation coil; the control electrode of the first electronic switch and the control electrode of the second electronic switch are electrically connected with a control signal generation module; the positive electrode of the energy storage element is electrically connected with the positive electrode of a third electronic switch of a second electronic switch group and the negative electrode of a fourth electronic switch of the second electronic switch group; the true magnetic stimulation coil and a false magnetic stimulation coil are both electrically connected with the negative electrode of the energy storage element; and the control electrode of the third electronic switch of the second electronic switch group and the control electrode of the fourth electronic switch of the second electronic switch group are electrically connected with the control signal generation module.

Description

【Technical field】 [0001] The invention relates to the technical field of transcranial magnetic stimulation, in particular to a true and false pulse magnetic stimulation therapeutic apparatus. 【Background technique】 [0002] Transcranial magnetic stimulation (TMS) mainly stimulates specific areas of the brain through a magnetic field, and uses a time-varying magnetic field to generate an induced current in the cerebral cortex, which causes a series of physiological and biochemical changes by causing changes in brain metabolism and neural electrical activity. Response, on this basis to achieve the purpose of treatment. [0003] Repetitive transcranial magnetic stimulation (rTMS) was invented on the basis of TMS, and it is currently used clinically to treat negative symptoms of schizophrenia. However, the literature lacks observations of the persistence of efficacy after cessation of the treatment. It is necessary to compare long-term comparisons between patients who receive ...

Problems solved by technology

[0004] The existing comparison between true and false stimulation is mainly to turn the "8" shaped coil by 90°. At this time, it is equivalent to the sound of "da da da" heard by the patient, and the vibration feeling is the same as that of the real stimulation group, but because with the coil As the distance to the head increases, the generated magnetic field also increases with the distance, so it gradually attenuates, and the stimulation intensity decreases by about 80% when it reaches the deep tissue in the brain

Because the existing scheme only relies on changing the angle of the magnetic stimulation coil to reduce the magnetic stimulation received by the patient's head, but it cannot truly achieve "zero stimulation" in the pseudo-stimulation
