Technical Field
[0001] The invention relates to the field of brain science detection equipment, in particular to an electroencephalogram (EEG) headband assembly connection structure and an EEG headband wearing method. Background Art
[0002] EEG is an electrical signal that can reflect the health and cognitive activities of the human brain. It is an important parameter for the diagnosis and treatment of brain diseases and cognitive neuroscience. As an EEG acquisition device, EEG headband is widely used because it is non-invasive and portable compared to other EEG acquisition methods. Users wear the EEG headband on their heads so that the electrodes on the headband can collect EEG signals.
[0003] In actual use, due to the differences in the skull shapes of users, the deformation degree of the headband body with a hard structure is small, which affects the fit between the electrode and the user's head. In order to make the electrode close to the head, the headband needs to be tightened to increase the pressure. In this case, the electrode probe will make the user feel uncomfortable, affecting the user experience. In addition, due to the connection structure limitations between the headband body and the EEG acquisition device, the deformation degree of the headband body when adapting to the shape of the user's head is also limited, resulting in the headband body losing a better fit due to the limitations of the EEG acquisition device. In addition, although the existing EEG headband with a fabric structure solves the problem of click fit, there is a problem that the surface of the headband is easily contaminated and is not easy to clean and disinfect. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide an EEG headband assembly connection structure and an EEG headband wearing method that better fits the wearer's head.
[0005] The technical solution adopted by the present invention to solve its technical problems is: an EEG headband assembly connection structure, including a headband body and an EEG acquisition device, the EEG acquisition device including a flexible circuit board, an electrode female buckle is arranged on the back of the flexible circuit board, and at least one EEG detection head is arranged on the inside of the headband body, including a face shell and a bottom shell, the bottom shell is made of a flexible material, the back of the flexible circuit board is tightly arranged with the bottom shell, the electrode female buckle on the back of the flexible circuit board passes through the bottom shell electrode hole on the bottom shell and is then arranged in the headband electrode hole on the outside of the headband body, the front of the flexible circuit board is tightly arranged with the face shell, and the face shell and the bottom shell are fixed as an integrated structure.
[0006] Furthermore, the surface shell and the bottom shell are made of silicone.
[0007] Furthermore, the face shell includes a charging port, and a charging plug passes through the charging port to charge the EEG acquisition device.
[0008] Furthermore, the headband body includes at least two headband electrode holes, and the bottom shell includes at least two bottom shell electrode holes. The headband electrode holes and the bottom shell electrode holes are arranged in a one-to-one correspondence, and each headband electrode hole corresponds to an EEG acquisition device with different parameter specifications.
[0009] Furthermore, Velcro is provided at the ends of both ends of the headband body, and the headband body is formed into a ring shape by the Velcro that fits together and is then fixed to the wearer's head.
[0010] Furthermore, the headband body is made of elastic fabric.
[0011] The method for wearing an EEG headband comprises the following steps: a. firstly, the back side of a flexible circuit board of an EEG acquisition device is tightly fitted with a bottom shell, and the electrode female buckle on the back side of the flexible circuit board is passed through the bottom shell electrode hole on the bottom shell, and then the face shell is set on the front side of the flexible circuit board, and silicone glue is injected between the face shell and the bottom shell to fix the face shell and the bottom shell into an integrated structure; b. The electrode female buckle on the back side of the flexible circuit board is aligned with the head ring electrode hole on the outside of the head ring body, and then the electrode female buckle is inserted into the head ring electrode hole, and finally the electrode is installed into the electrode female buckle; c. The headband body is worn on the wearer's brain, and the headband body is enclosed into a ring shape by Velcro at both ends of the headband body, and then fixed on the wearer's head.
[0012] The beneficial effect of the present invention is that: in actual use, firstly, a sandwich space of an integrated structure for accommodating an EEG acquisition device is constructed by the face shell and the bottom shell, and the EEG acquisition device is arranged in the sandwich space. Then, the electrode female buckle on the back of the flexible circuit board of the EEG acquisition device passes through the bottom shell electrode hole on the bottom shell and protrudes outward, and is then arranged in the head ring electrode hole outside the head ring body, forming a connection structure in which the EEG acquisition device and the face shell and the bottom shell are arranged together on the outside of the head ring body. The bottom shell is made of a flexible material, so that there is a deformation accommodation space between the head ring body and the EEG acquisition device. The above connection method allows the connection between the EEG acquisition device and the head ring body to be unaffected by the deformation of the head ring body when the head ring body is deformed to adapt to the shape of the patient's head, so that the head ring body can have a larger deformation space during design and use, and thus fits better with the head.

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 Shown are the main components of the EEG headband. Figure 1 The headband body 1 is shown in the figure. The headband body 1 is made of elastic fabric and can be adapted to different skull shapes. At the same time, the elastic fabric headband body 1 further improves the headband body 1 to have a larger deformation space, so that the connection between the EEG acquisition device and the headband body 1 is not affected by the deformation of the headband body. A number of EEG detection heads 11 are arranged on the inner wall of the headband body 1. Since in this solution, when the headband body is deformed to adapt to the shape of the patient's head, the connection between the EEG acquisition device and the headband body is not affected by the deformation of the headband body, so that the headband body can have a larger deformation space during design and use, and thus fit the head better. Therefore, the EEG detection head 11 can better fit the patient's head, so that the collected EEG signal is more accurate. Velcro 12 is arranged at the ends of both ends of the headband body 1. After the Velcro 12 is attached to each other, the headband body 1 is formed into a ring, so as to be fixed to the patient's head. The Velcro 12 allows the circumference of the headband body 1 to be adjusted, and the fitting angle and position of the Velcro 12 can also be adjusted, so that the headband body 1 can be slightly twisted, so as to better adapt to the wearing requirements of the headband body 1 at different angles, and ensure that the EEG detection head 11 on the headband body 1 can better fit the patient's head. Among them, the headband body 1 has several electrode holes and charging ports built in, which can be adapted to different EEG acquisition devices and has stronger flexibility of use.
[0020] When the existing EEG acquisition device is set on the headband body 1, the EEG acquisition device must first be placed between the bottom shell 2 and the face shell 3 through the interlayer space formed by the bottom shell 2 and the face shell 3, and the bottom shell 2 and the face shell 3 are silicone shells. The EEG acquisition device is used to collect and send the user's EEG signals, and the back of the flexible circuit board is provided with an electrode female buckle, which can be adapted to non-invasive dry electrodes and wet electrodes. The EEG acquisition device has a built-in Bluetooth module to achieve communication with the host computer (mobile phone, computer, customized equipment), and can display and store the EEG data collected by the headband body 1 and the working status of the headband body 1 on the host computer. The EEG acquisition device can also add stimulation electrodes to regulate sleep or neurological diseases, and realize control through the host computer.
[0021] like Figure 2 As shown, four bottom shell electrode holes are provided on the bottom shell 2, and the bottom shell electrode holes are used to allow the electrode female buckles on the back of the flexible circuit board to pass through, and the electrode female buckles on the back of the flexible circuit board are set in the head ring electrode holes outside the head ring body 1, so as to realize the connection between the flexible circuit board of the EEG acquisition device and the head ring body 1. Figure 3 and Figure 4 As shown, it is an embodiment of the face shell 3, and the face shell 3 is provided with a battery pack 31, a button protection 33 and a charging port 32, so that the power supply, pressing control and power replenishment of the EEG acquisition device are realized without removing the bottom shell 3. In actual use, once it is necessary to replace another model of EEG acquisition equipment, it is only necessary to remove the original EEG acquisition equipment from the headband body 1 and then replace it with a new EEG acquisition equipment. Among them, the new EEG acquisition equipment also has a corresponding bottom shell 2 and a face shell 3, so it is convenient to realize the connection between the flexible circuit board of the EEG acquisition equipment and the headband body 1, as well as the power supply, pressing control and power replenishment of the EEG acquisition equipment. At the same time, due to the presence of the bottom shell 2 and the face shell 3, a deformation buffer space is provided for the connection between the EEG acquisition equipment and the headband body 1, thereby further reducing the constraint on the deformation space of the headband body 1 due to the EEG acquisition equipment being fixed on the headband body 1, so that the headband body 1 can have a larger deformation amount, which is conducive to fitting the patient's head.
