Problems solved by technology

[0003] During the use of the transcranial electrical stimulator, it is necessary to fix the stimulating electrodes on the scalp area corresponding to the target brain area. Whether the stimulating electrodes are connected to the human scalp correctly will directly affect the normal operation and therapeutic effect of the transcranial electrical stimulation equipment. It is easy for the electrode to fall off
[0004] However, some of the traditional transcranial electrical stimulators do not have the function of detecting and alarming electrode falling off, and some instruments can issue an alarm for electrode falling off in the DC stimulation mode, but they cannot indicate which electrode is falling off.
These practical problems lead to lower safety and convenience of transcranial electrical stimulators in actual use

Embodiment 1

[0020] see figure 1 , a kind of transcranial electrical stimulation electrode shedding monitoring alarm device of an example of the present invention is made up of signal acquisition module 1, detection and judgment module 2, alarm module 3, and described signal acquisition module 1 is connected with detection and judgment module 2, and detection and judgment module 2 is connected with the alarm module 3.

[0021] The signal acquisition module 1 is connected to the output electrode channel of the transcranial electrical stimulator (the stimulator can choose the 1*1tES electrical stimulator of sorterix company here), and is used to collect the effective value of the output current of each channel of the transcranial electrical stimulator and the RMS value of the single-point terminal voltage at the output point.

[0022] The detection and judgment module 2 detects and judges in real time whether the electrodes on each stimulation channel fall off according to the data transmit...

Embodiment 2

[0025] see figure 2 , is the transcranial electrical stimulation electrode shedding detection method of an example of the present invention, comprises following steps:

[0026] S1: Connect the signal acquisition module 1 of the device to the output electrode channel of the transcranial electrical stimulator.

[0027] S2: The signal acquisition module 1 connects a precision resistor with a precision of 0.1% and a resistance value of 10 ohms into the output electrode channel in series, and the output current value can be converted by sampling the voltage of the precision resistor with a small resistance value, and then through the real The effective value numerical processing method obtains the effective value Ia of the electrode output current, connects the electrode output point to a resistance attenuation network, and obtains the value of the terminal voltage by measuring the attenuated voltage value, and then obtains the single-point terminal voltage through the true effect...

Abstract

The invention provides a tES (transcranial electrical stimulation) electrode falling-off monitoring alarm device and an application thereof. The device comprises a signal acquisition module, a detection judgment module and an alarm module, wherein the signal acquisition module is connected with the detection judgment module, and the detection judgment module is connected with the alarm module. Thedevice is reasonable in design, simple and convenient to prepare, low in cost and capable of detecting whether each electrode falls off in real time and giving an alarm in time under the condition offalling off; the problem about monitoring alarm of electrode falling off of a current transcranial electric stimulator is solved, and safety and convenience of the transcranial electric stimulator inthe using process are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a monitoring and alarm device for electrode drop-off during transcranial electrical stimulation and its application. Background technique [0002] Transcranial Electrical Stimulation (tES) is a non-invasive neuromodulation technology that uses electrodes to apply low-intensity micro-currents to specific brain regions on the surface of the scalp, thereby regulating the neural activity of the cerebral cortex. According to different stimulation current types, tES can be divided into transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), transcranial pulse current stimulation (tPCS), etc. , tES has a wide range of applications in the treatment of mental and neurological diseases, stroke rehabilitation, cognitive learning ability improvement and other fields. [0003] During the use of the transcranial electrical stimu...
