Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The present embodiment provides a transcranial electrical stimulation device for use in a motor cortex, the device comprising: the device comprises a body, a stimulation electrode, a detection electrode, a controller and a switching module. Specifically, the body of the embodiment is a head-wearing type, the body includes a strap, and a stimulating electrode is disposed on the inner side of the body, and the position of the stimulating electrode on the body corresponds to the position of a brain movement region, which is the position of a movement cortex on the brain of a human body, that is, corresponds to the left central region and the right central region of the brain (i.e., the C3/C4 region of the head). Because the stimulating electrode of the embodiment is arranged corresponding to the brain movement area, the stimulating electrode can be controlled to emit weak current to stimulate the brain movement area, thereby improving the movement response capability of the user and improving the movement capability of the user. In addition, the transcranial electric stimulation device of the embodiment further comprises a detection electrode, a controller and a switching module, wherein the detection electrode is arranged on the inner side of the body and is used for detecting brain electrical signals, the controller is connected with the stimulation electrode and the detection electrode, and the switching module is connected with the controller and is used for switching the working states of the stimulation electrode and the detection electrode. When the device is specifically applied, the switching module can switch the detection electrode work or the stimulation electrode work according to the use requirement of a user, so that the requirements of detecting brain electrical signals and stimulating brain movement areas are met in the process of using the transcranial electrical stimulation device.
Specifically, after the user wears the transcranial electric stimulation device on his head, a start instruction of the user can be received, for example, the user presses a start key, at this time, the controller receives the start instruction, and first controls the detection electrode to start working, at this time, the detection electrode detects initial electroencephalogram data of the user, and the initial electroencephalogram data at this time is an electroencephalogram signal which the user has not stimulated electrically. After the detection of the initial electroencephalogram data is finished, the controller gives an instruction to the switching module, the switching module starts to switch the stimulating electrode to work, at the moment, the stimulating electrode outputs weak current, the intensity of the weak current can be 0.8mA, and because the stimulating electrode of the embodiment corresponds to the C3/C4 area of the head, the movement reaction capacity of a user can be improved and the movement capacity of the user can be improved through stimulating the C3/C4 area of the head by the weak current.
In one implementation manner, the plurality of stimulation electrodes in this embodiment may be arranged and disposed uniformly, so that when weak electric stimulation is conveniently performed on the brain movement area, the stimulation electrodes may be stimulated uniformly, so as to achieve the optimal stimulation effect. In addition, in order to avoid interference between the stimulating electrode and the detecting electrode, the stimulating electrode and the detecting electrode are arranged at a preset distance, so that the working areas of the detecting electrode and the stimulating electrode are different, interference of the stimulating electrode on the brain electrical signal detected by the detecting electrode is avoided, and the detected brain electrical signal is ensured to be accurate.
In one implementation, in order to improve the comfort level of contact between the detection electrode and the stimulation electrode and the head of the user, the stimulation electrode and the detection electrode in this embodiment are both disposed on an elastic component, and the elastic component is embedded in the inner side of the body, and is used for adjusting the contact areas and the contact tightness between the stimulation electrode and the detection electrode and the brain of the user. When the device is specifically applied, the elastic component of the embodiment can be set as a spring, the detection electrode and the stimulation electrode can be set as conical shapes, and the angle and the position can be freely adjusted due to the fact that the stimulation electrode and the detection electrode are both set to be elastic, so that the contact degree of the stimulation electrode and the detection electrode with the brain of a user can be adjusted, and the contact area and the contact compactness of the stimulation electrode and the detection electrode with the brain of the user are further affected. Thus, when the transcranial electrical stimulation device is worn by a user, the detection electrode and the stimulation electrode can be finely adjusted based on the shape of the head of the user, so that good contact between the detection electrode and the stimulation electrode and the brain movement area of the user is maintained. And when the detection electrode or the stimulation electrode works, the contact area and the contact compactness of the stimulation electrode or the detection electrode and the brain of the user can be adjusted based on the use requirement of the user, so that the good contact between the stimulation electrode or the detection electrode and the brain of the user is ensured, and the accurate detection and the accurate electrical stimulation are realized. In another implementation, when the contact area between the stimulation electrode and the brain of the user is larger or the contact tightness is higher, the stimulation effect on the brain of the user is better, based on this, the embodiment can adjust the contact area and the contact tightness of the stimulation electrode and the brain of the user based on the elastic component according to the expected stimulation effect, so as to improve the stimulation effect.
In another implementation, a pressure sensor may be further provided on the inside of the body of the present embodiment, which may detect the pressure state between the transcranial electrical stimulation device and the user's head in real time, thereby determining whether the device is in place or at risk of falling off. When the pressure value detected by the pressure sensor is lower than a preset pressure threshold value after the user wears the transcranial electric stimulation device, the fact that the transcranial electric stimulation device is not tightly contacted with the brain of the user at the moment can be determined, prompt information can be sent out at the moment, and the binding band can be automatically adjusted, so that the transcranial electric stimulation device is tightly contacted with the brain of the user, and the wearing state of the transcranial electric stimulation device is automatically adjusted. And when the pressure value detected by the pressure sensor reaches the pressure threshold value, the transcranial electric stimulation device can be judged to be worn in place, and the transcranial electric stimulation device can be started to start working at the moment.
Based on the above embodiment, the present invention further provides a control method based on the above transcranial electro-stimulation device applied to a sports cortex, as shown in fig. 1, the control method includes the following steps:
step S100, acquiring pressure data, and starting the transcranial electric stimulation device based on the pressure data.
The pressure sensor is arranged on the body of the transcranial electric stimulation device, and the pressure sensor can detect the pressure state between the transcranial electric stimulation device and the head of a user in real time, so that whether the device is worn in place or the risk of falling off is judged. After the transcranial electric stimulation device is worn by a user, the transcranial electric stimulation device can be judged to be worn in place after the pressure value detected by the pressure sensor reaches the pressure threshold value, and then the transcranial electric stimulation device can be started to start working. When the pressure value detected by the pressure sensor is lower than a preset pressure threshold, the fact that the transcranial electric stimulation device is not tightly contacted with the brain of the user at the moment can be determined, prompt information can be sent out at the moment, and the binding band can be automatically adjusted, so that the transcranial electric stimulation device is tightly contacted with the brain of the user, and the wearing state of the transcranial electric stimulation device is automatically adjusted.
Step 200, controlling a stimulation electrode arranged on the transcranial electric stimulation device to be in contact with the brain of a user, and performing micro-electric stimulation on a brain movement area based on the stimulation electrode, wherein the brain movement area comprises: left and right central regions of the brain.
Specifically, after the user wears the transcranial electric stimulation device on his head, a start instruction of the user can be received, for example, the user presses a start key, at this time, the controller receives the start instruction, and first controls the detection electrode to start working, at this time, the detection electrode detects initial electroencephalogram data of the user, and the initial electroencephalogram data at this time is an electroencephalogram signal which the user has not stimulated electrically. After the detection of the initial electroencephalogram data is finished, the controller gives an instruction to the switching module, the switching module starts to switch the stimulation electrode to work, and at the moment, the stimulation electrode outputs weak current, the intensity of the weak current can be 0.8mA, and because the stimulation electrode of the embodiment corresponds to the C3/C4 area of the head, the movement reaction capacity of a user can be improved and the movement capacity of the user can be improved by stimulating the C3/C4 area of the head (namely corresponding to the left central area and the right central area of the brain) through the weak current.
Step S300, acquiring current brain electrical signal data based on a detection electrode arranged on the transcranial electrical stimulation device, and adjusting the contact area and the contact tightness between the stimulation electrode and the brain movement area based on the current brain electrical signal data.
In one implementation manner, after the micro-electrical stimulation is performed on the brain movement area of the user based on the stimulation electrode, the present brain electrical signal data can be obtained by switching the detection electrode based on the switching module again, and the stimulation effect of the stimulation electrode is judged based on the present brain electrical signal data and the initial brain electrical signal data, so that when the stimulation effect does not reach the standard, the contact area and the contact compactness between the stimulation electrode and the brain movement area are adjusted. Specifically, the stimulating electrode of this embodiment is disposed on an elastic component, the elastic component is embedded in the inner side of the body, and the elastic component is used for adjusting the contact area and the contact tightness between the stimulating electrode and the brain of the user. When the device is specifically applied, the elastic component of the embodiment can be set as a spring, the stimulation electrode can be set as a cone, and the angle and the position can be freely adjusted due to the fact that the stimulation electrode is set to be elastic, so that the contact degree of the stimulation electrode and the brain of a user can be adjusted, and the contact area and the contact compactness of the stimulation electrode and the brain of the user are affected. Thus, when the transcranial electrical stimulation device is worn by a user, the stimulation electrodes can be fine-tuned based on the shape of the user's head, so that good contact is maintained between the user's brain movement area and the stimulation electrodes. In another implementation manner, when the contact area between the stimulation electrode and the brain of the user is larger or the contact compactness is higher, the stimulation effect on the brain of the user is better, based on this, the embodiment can adjust the contact area and the contact compactness between the stimulation electrode and the brain of the user according to the stimulation effect judged by the current brain electrical signal data and the initial brain electrical signal data, so as to improve the stimulation effect. In another implementation manner, the detection electrode of the embodiment may also be disposed on the elastic component, so that a contact area and a contact tightness between the detection electrode and the brain of the user may also be adjusted, thereby ensuring accuracy of the detected electroencephalogram data.
In a specific application, the present embodiment may first control the stimulation electrode to extend to a first position for contacting the stimulation electrode with the brain movement region when adjusting the contact area and the contact tightness between the stimulation electrode and the brain movement region. And then, acquiring a last stimulation scheme of the transcranial electric stimulation device, and controlling to perform micro-electric stimulation on the brain movement area based on the stimulation scheme, wherein the stimulation scheme comprises micro-current intensity and micro-electric stimulation duration. And after the previous stimulation scheme is used for stimulation, current electroencephalogram data is acquired, and the change amplitude of the electroencephalogram is determined based on the current electroencephalogram data and reflects the change between the current electroencephalogram data and the initial electroencephalogram data. Next, the present embodiment determines the stimulation effect of the stimulation electrode based on the amplitude of the brain electrical signal variation. And if the stimulation effect does not reach the standard, that is, the change between the current electroencephalogram data and the initial electroencephalogram data is not large, controlling the stimulation electrode to extend to a second position, wherein the second position is more convex than the first position. At this time, the stimulation scheme can be adjusted, and the micro-electric stimulation is continuously performed on the brain movement area based on the adjusted stimulation scheme, and the stimulation effect is better due to the fact that the contact area between the stimulation electrode and the brain of the user is larger and the contact compactness is higher, so that the use requirement of the user is met.
In summary, the cranial electric stimulation device of the present embodiment acts on the brain movement area corresponding to the movement cortex, that is, the left central area and the right central area of the brain, so that the movement function of the user can be improved and the use experience of the user can be improved based on the cranial electric stimulation device.
