Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an electroencephalogram (EEG) signal acquisition device. Background Technology

[0002] Electroencephalography (EEG) plays a vital role in medical diagnosis and treatment. It not only aids in the diagnosis and treatment of diseases such as epilepsy but also provides crucial information for the diagnosis of other neurological disorders. For example, EEG can determine whether a patient has epilepsy, the type and nature of the seizures, assist doctors in assessing the effectiveness of antiepileptic drugs and adjusting dosages, and pinpoint the location of epileptic foci, providing important information for surgery. Furthermore, EEG can also be used to assist in the diagnosis of other neurological disorders, such as headaches, migraines, syncope, brain tumors, brain injuries, and intracranial infections.

[0003] Current electroencephalography (EEG) methods involve using electrodes in an EEG sensor that are placed close to the scalp to collect data. After amplification and filtering, the EEG signals are converted into visual waveforms. Therefore, the sensor needs to be worn for extended periods during the data collection process to capture brain activity in different states.

[0004] However, existing EEG signal acquisition devices are often designed to be too complex, requiring professional assistance to wear them, and the wearer needs to maintain the same posture for as long as possible to avoid shaking, which could cause poor connection or unstable signal transmission, thus failing to meet the needs for convenience and comfort. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0024] The present invention provides a detailed description of an electroencephalogram (EEG) signal acquisition device in conjunction with the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the electroencephalogram (EEG) signal acquisition device provided by this utility model. Figure 1 As shown, the EEG signal acquisition device includes: an elastic headband 100, an EEG signal transmission device 200, and an EEG signal acquisition device 300; wherein, the EEG signal acquisition device 300 is disposed on the inner side of the elastic headband 100 for acquiring EEG signals, and the EEG signal transmission device 200 is disposed on the outer side of the elastic headband 100 for transmitting the received EEG signals to an external platform (not shown in the figure).

[0026] Here, the elastic headband 100 can be an elastic band or a fixing band including a movable buckle. When it is necessary to collect EEG signals, without the assistance of others, the wearer can simply pull the elastic headband 100 or open the movable buckle of the elastic headband 100 to put it on the head, and then loosen the elastic headband 100 or reassemble the movable buckle of the elastic headband 100 to secure it firmly to the head. It has the advantages of being convenient to wear and easy to use. In addition, the elastic headband 100 is detachably connected to the EEG signal transmission device 200 and the EEG signal acquisition device 300 for easy cleaning.

[0027] Here, to increase the contact area between the EEG signal acquisition device 300 and the scalp, and reduce the problem of poor contact between the EEG signal acquisition device 300 and the wearer's scalp, the EEG signal acquisition device 300 is shaped as either a rectangular sheet structure or a rounded rectangular sheet structure. Furthermore, the EEG signal acquisition device 300 is an FPC electrode, also known as a flexible printed circuit board. As the name suggests, an FPC electrode is a printed circuit made of a flexible insulating substrate, which can be freely bent, rolled, and folded, and can withstand millions of dynamic bends without damaging the wires. In one possible implementation, the FPC electrode includes: a plurality of spaced-apart electrodes 310, the electrode 310 being made of a material selected from gold plating, immersion gold, and silver. The plurality of electrodes 310 are integrally formed. The FPC electrode is in close contact with the wearer's forehead scalp to acquire EEG signals from the wearer's forehead. Exemplarily, the number of electrodes is three, and these three electrodes are spaced apart along the axial direction of the elastic headband 100. It should be understood that this invention does not limit the number of electrodes. The number of electrodes can be increased to further improve the sensitivity of the EEG signal acquisition device 300. Using FPC electrodes to acquire EEG signals can effectively improve the accuracy and comprehensiveness of data acquisition. Furthermore, the FPC electrodes are designed as rectangular or rounded rectangular sheets, which reduces the overall weight of the device, allowing for prolonged wear without excessive burden, thus improving comfort and convenience. In addition, it helps to integrate more electrodes and functional modules within a limited space, improving space utilization.

[0028] Figure 2 This is a schematic diagram of the electroencephalogram (EEG) signal transmission device provided by this utility model. Figure 2 As shown, the EEG signal transmission device 200 includes: a housing 210, and a circuit board 220 disposed inside the housing 210 (see details). Figure 3 The circuit board 220 is equipped with a wireless transmission module 221 and a battery module 222.

[0029] Here, housing 210 includes: a first housing 211 and a second housing 212 that are detachably connected; the bottom of the second housing 212 is fixedly mounted on the elastic headband 100, wherein the circuit board 220 is mounted inside the second housing 212 by means of threaded fixing.

[0030] For example, the first housing 211 and the second housing 212 are connected by means of movable snaps and screws.

[0031] Here, the EEG signal transmission device also includes a fixing plate 230 for fixing the second housing 212 to the elastic headband 100. Specifically, the fixing plate 230 is threadedly connected to the second housing 212, and the fixing plate 230 is also threadedly connected to the elastic headband 100.

[0032] To understand the internal structure of the EEG signal transmission device, Figure 3 This is a schematic diagram of the internal structure of the electroencephalogram (EEG) signal transmission device provided by this utility model. Figure 3 As shown, the circuit board 220 is fixed inside the second housing 212 by threads, and the battery module 222 is used to power the wireless transmission module 221. In one possible implementation, the wireless transmission module is either a Bluetooth module or a WIFI module. For example, the Bluetooth module is model BG22A1. It should be understood that other models of Bluetooth modules or WIFI modules can also be used for signal transmission in this invention.

[0033] Please refer to Figure 1 and Figure 3 The elastic headband 100 has a through hole 110; the EEG signal acquisition device 300 and the wireless transmission module 200 are connected by a ribbon cable 320. One end of the ribbon cable 320 passes through the through hole 110 to connect with the EEG signal acquisition device 300, and the other end extends into the housing 210 to connect with the wireless transmission module 221.

[0034] In addition, the circuit board 220 is provided with several indicator light assemblies (not shown in the figure), and the first housing 211 is provided with several light-transmitting windows 2111 that allow the light from the indicator lights to escape. One indicator light assembly corresponds to one light-transmitting window 2111. By using the indicator light assemblies, it can be determined whether the EEG signal acquisition device is working properly and whether the signal acquisition is complete.

[0035] Here, a control switch (not shown in the figure) is also provided on the circuit board 220. The control switch can be manually closed or opened to turn on or off the connection between the battery module 222 and other components (wireless transmission module 221, indicator lights and FPC electrodes, etc.).

[0036] In actual operation, the wearer unfastens the movable buckle of the elastic headband 100 to wear the EEG signal acquisition device. After re-fastening the elastic headband 100, the EEG signal acquisition device 300 (FPC electrode) located inside the elastic headband 100 is in close contact with the wearer's forehead scalp. The wearer turns on the control switch, the indicator light illuminates, and the FPC electrode begins to acquire the wearer's EEG signals. Within a certain period of time, the acquired EEG signals are continuously sent to the wireless transmission module 221 (Bluetooth module). Subsequently, the Bluetooth module sends the EEG signals to an external platform so that the external platform can amplify, filter, and process the EEG signals to convert them into a visible waveform. After completing the EEG signal acquisition for the specified time, the wearer unfastens the movable buckle and removes the EEG signal acquisition device.

[0037] Existing EEG signal acquisition devices are often overly complex in design, requiring professional assistance to wear and the wearer to maintain the same posture for extended periods to prevent shaking, which can lead to poor connections or unstable signal transmission. These devices fail to meet the needs for convenience and comfort. This invention provides an EEG signal acquisition device that is secured to the wearer's head with an elastic headband. An EEG signal acquisition device inside the headband collects EEG signals in real time. It offers advantages such as easy wearability and high sensitivity. Furthermore, because the EEG signal acquisition and transmission devices are integrated, the real-time acquired EEG signals can be quickly transmitted to the transmission device, significantly reducing device weight and ensuring stable and reliable signal transmission. In addition, the elastic headband provides excellent stability, eliminating the need for the wearer to maintain the same posture for extended periods, making it highly comfortable and portable.

[0038] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
