Description

Technical Field

[0001] The present invention belongs to the technical field of brain infrared equipment, and in particular relates to a probe device with scalp impedance detection and a use method thereof. Background Art

[0002] Scalp impedance detection is a crucial technology in the fields of neuroscience, brain science research, and medical diagnosis. Scalp impedance detection can evaluate the contact status between the electrode and the scalp, which is crucial to ensure accurate signal acquisition and subsequent data analysis.

[0003] Traditional scalp impedance detection methods mostly rely on near-infrared signals for judgment, but this method has many shortcomings; when penetrating the scalp and hair, near-infrared signals will be affected by many factors, such as hair thickness, density, and scalp oil secretion, etc. These factors will cause signal attenuation and deformation, thereby affecting the accuracy of impedance detection. Therefore, relying solely on near-infrared signals to judge the contact status of the probe often results in large errors; at the same time, in the traditional scalp impedance detection process, the operator needs to manually adjust the position of the electrode to ensure good contact between the electrode and the scalp. This method is not only time-consuming and labor-intensive, but also difficult to ensure that each electrode can achieve the best contact state. Summary of the invention

[0004] The purpose of the present invention is to provide a probe device with scalp impedance detection and a method of using the same in order to solve the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the invention adopts the following technical scheme: a probe device with scalp impedance detection, including a flexible head cover for covering the head and for mounting the probe, a plurality of bases are installed on the flexible head cover, a plurality of bases are respectively provided with fixing seats, an electromagnet is respectively installed on the inner side of a plurality of fixing seats, a plurality of fixing seats are respectively sleeved on the outer side of a plurality of fixing seats for mounting the probe, a plurality of mounting seats are respectively provided with magnetic seats that repel the electromagnet, a plurality of reset springs are respectively provided between the mounting seats and a plurality of bases, and an electrode sheet A and an electrode sheet B located on both sides of the probe are installed on the lower ends of a plurality of mounting seats.

[0006] By adopting the above technical solution, the design provides convenience and stability for probe installation by covering the head with a flexible head cover. The setting of the base, fixing seat and electromagnet allows each probe to be fine-tuned through the magnetic seat and reset spring to adapt to different head shapes and scalp conditions, ensuring close contact between the probe and the scalp, thereby improving the accuracy of impedance detection.

[0007] Optionally, several of the bases are cylindrical, several of the upper ends of the bases are provided with grooves, several of the inner sides of the grooves are provided with controllers, several of the open ends of the grooves are provided with covers for protecting the controllers, and several of the covers are provided with indicator lights electrically connected to the controllers.

[0008] By adopting the above technical solution, the cylindrical base design is easy to install and fix. At the same time, the controller and indicator light in the groove provide real-time detection status feedback. The controller is responsible for processing impedance data, and the indicator light displays the contact status of the electrode sheet and the scalp in an intuitive way, which is convenient for users or operators to make quick judgments.

[0009] Optionally, slide seats are respectively installed on the outer sides of several of the mounting seats, and slide grooves for the slide seats to slide are respectively opened on the inner side walls of several of the bases.

[0010] By adopting the above technical solution, the design of the slide and the slide groove allows the mounting seat to be fine-tuned on the base, further enhancing the flexibility of the contact between the probe and the scalp and ensuring the stability of the mounting seat during adjustment.

[0011] Optionally, several of the mounting seats are cylindrical, and mounting grooves are respectively provided at the upper ends of several of the mounting seats, and connecting seats for mounting the magnetic seats are respectively installed on the bottom walls of several of the mounting grooves.

[0012] By adopting the above technical solution, the cylindrical mounting base design facilitates the installation of the magnetic base and the electrode sheet, while the mounting groove and the connecting base provide a stable support for the magnetic base. This design ensures the stability and reliability of the magnetic base during the adjustment process, thereby improving the accuracy of the probe position adjustment.

[0013] Optionally, the bottom walls of the plurality of mounting seats and the inner side walls of the plurality of bases are respectively provided with fixing grooves for installing the reset springs, and the diameters of the plurality of reset springs are respectively larger than the diameters of the plurality of fixing seats.

[0014] By adopting the above technical solution, the setting of the reset spring enables the mounting base to quickly return to the initial position when it is magnetically repelled. At the same time, the fixing groove provides an installation space for the reset spring. This design not only helps to fine-tune the probe position, but also provides an automatic adjustment function when the probe is in poor contact with the scalp, thereby ensuring the continuity of impedance detection.

[0015] Optionally, wiring channels are respectively provided on some of the mounting seats and some of the bases.

[0016] By adopting the above technical solution, the setting of the wiring channel enables the connecting wires between components such as the electrode sheet, controller and indicator light to be neatly arranged inside the base and the mounting base, avoiding external interference and damage. This design improves the reliability and service life of the entire device.

[0017] Optionally, a rubber pad is installed on one side of the mounting seats close to the scalp, and the lower surfaces of the electrode sheets A and the electrode sheets B are at the same horizontal position as the surfaces of the rubber pads.

[0018] By adopting the above technical solution, the setting of the rubber pad not only improves the comfort of the contact between the electrode and the scalp, but also reduces the influence of external interference on impedance detection. At the same time, the electrodes A and B are at the same horizontal position as the surface of the rubber pad, ensuring sufficient contact between the electrode and the scalp, thereby improving the accuracy of impedance detection.

[0019] Optionally, the lower ends of the plurality of fixing seats are respectively provided with adjustment grooves for installing the plurality of electromagnets, and the inner side walls of the plurality of adjustment grooves are respectively provided with anti-interference layers.

[0020] By adopting the above technical solution, the setting of the adjustment slot allows the electromagnet to be fine-tuned in the fixing seat to adapt to different head shapes and scalp conditions. At the same time, the setting of the anti-interference layer reduces the impact of electromagnetic interference on the electromagnet and the probe, ensuring the accuracy and stability of impedance detection.

[0021] Optionally, a method for using a probe device with scalp impedance detection comprises the following steps:

[0022] Wearing the flexible headgear on the head;

[0023] The controller on each base starts the corresponding electrode sheet A and the electrode sheet B to perform impedance detection, and compares the impedance value with a preset threshold;

[0024] When the impedance value is less than the preset threshold, the indicator light turns green, indicating good contact;

[0025] When the impedance value is greater than a preset threshold, the indicator light turns red, indicating poor contact;

[0026] When the contact is poor, the control unit on the controller transmits current to the electromagnet to adjust the position of the mounting seat;

[0027] Until all the indicator lights change from red to green, the probe detects the scalp.

[0028] By adopting the above technical solution, the method of use achieves close contact between the probe and the scalp and the accuracy of impedance detection through automated and intelligent means, and realizes automatic adjustment of the electrode position and real-time monitoring of impedance detection through data processing of the controller and control of the control unit. This method of use not only improves the detection efficiency, but also reduces the difficulty of operation and human errors, making the entire detection process more convenient and reliable.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention directly installs a probe device with electrode sheets (electrode sheet A and electrode sheet B) on a flexible headgear, and utilizes the principle of repulsion between an electromagnet and a magnetic base to achieve fine-tuning and close contact between the electrode sheets and the scalp; this method effectively avoids the signal attenuation and deformation problems caused by factors such as hair thickness, density, and scalp oil secretion in traditional near-infrared signal detection, thereby significantly improving the accuracy of impedance detection, which is crucial for accurate signal acquisition and subsequent data analysis in the fields of neuroscience, brain science research, and medical diagnosis.

[0031] 2. The present invention installs a controller on each base and is equipped with an indicator light. The controller can immediately give feedback by detecting the impedance value between the electrode sheet and the scalp in real time and comparing it with the preset threshold value. When the impedance value is less than the preset threshold value, the indicator light shows green, indicating good contact; when the impedance value is greater than the preset threshold value, the indicator light shows red, indicating poor contact. This real-time feedback mechanism enables the operator to quickly understand the contact status of the electrode and take corresponding adjustment measures to ensure the detection quality.

[0032] 3. In the traditional scalp impedance detection process, the operator needs to manually adjust the electrode position, which is not only time-consuming and labor-intensive, but also difficult to ensure the optimal contact state of each electrode. The present invention automatically controls the magnetic force generated by the electromagnet through the controller, so that the mounting base and the electrode sheet thereon can be adjusted according to the actual situation of the scalp until the optimal contact state is achieved. This automated adjustment process greatly improves the detection efficiency and reduces the errors caused by human operation. BRIEF DESCRIPTION OF THE DRAWINGS

The flexible head cover 1 can be tightly covered on the head to provide a stable installation platform for the probe 8. Its softness and elasticity ensure the comfort of the device, and also help to reduce the change of electrode position caused by head movement. The flexible head cover 1 is provided with a plurality of hair-pulling holes 101. The design of the hair-pulling holes 101 allows the hair blocking the probe 8 to be peeled off by a hair-pulling rod;

[0042] Several bases 2 are installed on the flexible head cover 1, and several of the bases 2 are cylindrical. The cylindrical design enables the base 2 to be firmly installed on the flexible head cover 1 and provide support for subsequent components. Several of the bases 2 are respectively provided with grooves at their upper ends, and several of the inner sides of the grooves are respectively provided with controllers 201.

Electromagnets 4 are installed on the inner sides of several fixing seats 3. Electromagnets 4 generate magnetic fields when energized, and use the principle of repulsion between the same level to push the magnetic seat 6 and the mounting seat 5 to adjust their positions. This allows the electrode sheet to be fine-tuned according to the actual situation of the scalp to achieve the best contact state;

[0044] The outer sides of several of the fixing seats 3 are respectively sleeved with mounting seats 5 for installing the probes 8, and several of the mounting seats 5 are cylindrical.

Slide seats 504 are respectively installed on the outer sides of several of the mounting seats 5, and the inner side walls of several of the bases 2 are respectively provided with slide grooves 204 for the slide seats 504 to slide. The slide seats 504 on the outer sides of the mounting seats 5 cooperate with the slide grooves 204 on the inner sides of the base 2, so that the mounting seats 5 can be slid and adjusted on the base 2. This design ensures the stability and accuracy of the electrode sheet during the adjustment process. Wiring channels 505 are respectively provided on several of the mounting seats 5 and several of the bases 2. The wiring channels 505 provided on the mounting seats 5 and the base 2 are used to organize cables, thereby avoiding interference and inconvenience caused by cluttered cables.

At the same time, the softness and elasticity of the rubber pads 506 also help to reduce the changes in electrode position caused by head movement.

[0047] A method for using a probe device with scalp impedance detection comprises the following steps:

[0048] Wear the flexible headgear 1 on the head. The headgear should have good fit and breathability to ensure that it does not cause discomfort to the user during long-term wearing;

[0049] Through the control unit of the controller 201 on each base 2, the external device injects a weak high-frequency alternating current into the scalp through the electrode sheet A9. This current is usually very small to ensure that it does not cause any discomfort or harm to the user. At the same time, the electrode sheet B10 serves as a current receiving end and is responsible for collecting the current flowing through the scalp;

[0050] While injecting current, the controller 201 also measures the voltage drop on the scalp through the electrode sheet B10 or another independent voltage measurement electrode. This voltage drop is caused by the electrical impedance encountered when the current passes through the scalp;

[0051] The data processing unit in the controller 201 calculates the electrical impedance value of the scalp based on the injected current and the measured voltage drop. This calculation process usually follows Ohm's law (V=IR), where V is the voltage drop, I is the injected current, and R is the electrical impedance;

[0052] The calculated electrical impedance value is compared with a preset threshold value;

[0053] When the impedance value is less than the preset threshold, the indicator light 203 displays green, indicating that the electrode sheet A9 and the electrode sheet B10 are in good contact with the scalp and effective impedance measurement can be performed. The preset threshold is about 20k;

[0054] When the impedance value is greater than the preset threshold, the indicator light 203 displays red, indicating that the electrode sheet A9 and the electrode sheet B10 are not in good contact with the scalp and need to be adjusted;

[0055] When the indicator light 203 shows red, the control unit of the controller 201 on the corresponding base 2 will automatically start the adjustment mechanism, which usually includes an electromagnet 4 and a magnetic base 6. By transmitting current to the electromagnet 4 and utilizing the principle of repulsion between the same poles, the magnetic base 6 will drive the mounting base 5 and the electrode sheet A9 and the electrode sheet B10 thereon to make a slight position adjustment toward the scalp;

[0056] During the adjustment process, the control unit on the controller 201 will monitor the change of the impedance value in real time, and adjust the magnitude and direction of the current as needed to ensure that the electrode sheet can be accurately moved to the optimal position;

[0057] The current is regulated by the regulating unit on the controller 201, and the positions of the electrode sheets A9 and the electrode sheets B10 on the different bases 2 are continuously adjusted until the impedance detection of the scalp by all the electrode sheets A9 and the electrode sheets B10 meets the requirements, that is, the impedance value is less than the preset threshold value, and at this time, the indicator light 203 changes from red to green;

[0058] When the indicator lights 203 on all the bases 2 are green, it means that the contact state between all the electrode sheets A9 and the electrode sheets B10 and the scalp is optimal. At this time, the probe 8 on each base 2 can start to detect the scalp and collect the required physiological signals or data;

[0059] Before starting the measurement, the entire system should be checked for safety to ensure that all components are properly connected, not damaged or loose, and the electrode sheet, controller 201 and the entire system should be calibrated regularly to ensure the accuracy and reliability of the measurement results;

[0060] During the measurement process, if an abnormal situation occurs, such as the indicator light 203 continuously displays red, the system reports an error, etc.;

[0061] Check the status of indicator light 203: If the indicator light continues to show red, first check whether the electrode sheet A9 and the electrode sheet B10 are tightly attached to the scalp to ensure that there are no bubbles or foreign objects blocking the contact;

[0062] If the indicator light 203 still does not turn green after adjustment, consider whether there is any abnormality on the scalp surface, such as excessive oil, sweat, wounds, etc. These factors may affect the contact effect of the electrode sheet;

[0063] Check system connections: confirm that all wires and cables are tightly connected and not loose or disconnected, check whether the communication between the controller 201 and the external device is normal, and ensure that the data transmission is correct;

[0064] Restart the system: If none of the above steps resolve the issue, try shutting down the entire system and restarting it to clear possible software glitches or errors.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
