Embodiment 1

[0025] see figure 1 , is a schematic diagram of the structure of the present invention. The magnetically compatible transcranial electrical stimulation device mainly includes a wireless communication docking station 1, a magnetically compatible transcranial electrical stimulator 2, a magnetically compatible electrode lead wire 3 and a magnetically compatible electrode 44. part.

[0026] The computer in the control room is connected with the wireless communication docking station 1 in the magnetic resonance imaging scanning room, the connecting line passes through the waveguide, and the wireless communication docking station 1 receives and transmits data. The magnetically compatible transcranial electrical stimulator 2 in the magnetic resonance imaging scanning room receives and sends data, and establishes a two-way communication connection with the computer in the control room through the wireless communication docking station 1 . Among them, the magnetic compatibility transc...

Embodiment 2

[0030]The working process of the device of the present invention is described as follows: before the device works, use a lithium battery or an external power supply to supply power to the power management module 24, turn on the power switch of the stimulator before starting the magnetic resonance imaging scan, and then the power management module 24 supplies the stimulator to the stimulator. The control room computer uses the wireless communication docking station 1 to connect with the wireless communication module 25 of the stimulator through wireless communication to establish two-way communication with the stimulation device. The control room computer can set the relevant parameters of the stimulator. Including parameters such as stimulation time, stimulation current intensity, stimulation mode, etc., the setting parameters are transmitted to the main control module 22 through the wireless communication module 25, and the main control module 22 will control the signal generat...

Abstract

The invention discloses a magnetically-compatible transcranial electric stimulation device. A wireless communication mode is adopted, and through a wireless communication docking station connected toa control room computer, transcranial electric stimulation is carried out in a magnetic resonance imaging scanning room and bidirectional communication with the control room computer is realized; themagnetically-compatible transcranial electric stimulation device mainly comprises four parts: the wireless communication docking station, a magnetically-compatible transcranial electric stimulator, amagnetically-compatible electrode lead wire and a magnetically-compatible electrode; the magnetically-compatible transcranial electric stimulator can output current of + / -4mA, detects output current and electrode contact impedance in real time, carries out wireless communication, normally operates in a magnetic interference environment, does not interfere with a surrounding magnetic field environment, and is provided with a plurality of stimulation channels; and the magnetically-compatible electrode is formed by connecting carbon fibers to a rubber sheet. The device is reasonable in design, can be used in the magnetic resonance scanning room, and solves the problems that existing transcranial electric stimulation devices are difficult to realize magnetic compatibility, inconvenient to usein transcranial electric stimulation combined with magnetic resonance imaging, low in reliability and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a magnetically compatible transcranial electrical stimulation device, which is a transcranial electrical stimulation device that can be used in a magnetic resonance imaging scanning room. Background technique [0002] Transcranial electrical stimulation (tES) is a neuromodulation technique that restores the balance of neural networks in the patient's brain by injecting electrical current into the brain to enhance or inhibit the activity of the cerebral cortex, thereby improving brain disorders caused by neurological diseases. disfunction. Transcranial electrical stimulation mainly includes the following methods: transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), transcranial pulsed current stimulation (tPCS), Cranial random noise stimulation (transcranialrandom noise stimulation, tRNS) and cranial electrotherapy stimulati...
