Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0023] like Figures 1-3 As shown, a portable EEG acquisition device 100 (hereinafter referred to as acquisition device 100) in one embodiment of this utility model includes an acquisition module 10 and a processing module 20, both of which are housings with built-in installation space. The acquisition module 10 can connect to EEG caps with different electrodes, transmitting the received EEG signals to the processing module 20. The processing module 20 has a built-in signal processing module, data transmission module, power supply module, etc., used to receive and process the signals sent by the acquisition module 10, and send the processed signals to a back-end control terminal, for example, for display in image or digital form. The acquisition module 10 and the processing module 20 are detachably connected, allowing the processing module 20 to connect to and adapt to different acquisition modules 10, improving flexibility during use. Signal transmission between the processing module 20 and the terminal device can be wired, as wired data transmission has lower latency and is less susceptible to interference from other signals; alternatively, a more flexible wireless transmission method can be used, which is not limited in this embodiment.

[0024] In one embodiment, the acquisition module 10 and the processing module 20 employ a magnetic quick-release design. Specifically, the acquisition module 10 has a first magnetic element 18, and the processing module 20 has a second magnetic element 27 that can attract the first magnetic element 18. When the acquisition module 10 and the processing module 20 approach each other, they are fixed together by magnetic force. When it is necessary to transfer the processing module 20 to another acquisition module 10, they can be separated by forcefully prying them apart in a direction away from each other.

[0025] It is conceived that one of the first magnetic attraction member 18 and the second magnetic attraction member 27 is a magnet, and the other can also be a magnet, of course, other magnetic metals can also be selected, and the embodiment is not limited.

[0026] Preferably, a first limiting groove 11 for placing the first magnetic attraction member 18 is opened on the collection module 10, and a second limiting groove 21 for placing the second magnetic attraction member 27 is opened on the processing module 20. Such a setting mode can make the first magnetic attraction member 18 and the second magnetic attraction member 27 respectively embedded in the surface of the collection module 10 and the processing module 20, and can avoid displacement, thereby improving the overall stability.

[0027] Meanwhile, in order to improve the stability, a limiting structure for limiting the fixed position of the collection module 10 and the processing module 20 is arranged between the two, so as to prevent the two from being displaced during work, which may cause communication interruption and even sampling failure.

[0028] Specifically, the limiting structure includes a positioning block and a positioning groove for accommodating the positioning block, for example Figure 2 and 3 In the above two embodiments, a rectangular first positioning block 17 and a cylindrical second positioning block 12 are respectively arranged on the collection module 10, and a rectangular first positioning groove 24 and a circular second positioning groove 22 are respectively arranged on the processing module 20. When the collection module 10 and the processing module 20 are close to each other and fixed under the magnetic attraction, the first positioning block 17 is embedded in the first positioning groove 24, and the second positioning block 12 is embedded in the second positioning groove 22, so as to determine and limit the relative position of the collection module 10 and the processing module 20 when fixed, and prevent the two from being relatively displaced due to improper operation during work.

[0029] In the above two embodiments, a rectangular first positioning block 17 and a cylindrical second positioning block 12 are respectively arranged on the collection module 10, and a rectangular first positioning groove 24 and a circular second positioning groove 22 are respectively arranged on the processing module 20. When the collection module 10 and the processing module 20 are close to each other and fixed under the magnetic attraction, the first positioning block 17 is embedded in the first positioning groove 24, and the second positioning block 12 is embedded in the second positioning groove 22, so as to determine and limit the relative position of the collection module 10 and the processing module 20 when fixed, and prevent the two from being relatively displaced due to improper operation during work. Figure 2 and 3 In the above two embodiments, a rectangular first positioning block 17 and a cylindrical second positioning block 12 are respectively arranged on the collection module 10, and a rectangular first positioning groove 24 and a circular second positioning groove 22 are respectively arranged on the processing module 20. When the collection module 10 and the processing module 20 are close to each other and fixed under the magnetic attraction, the first positioning block 17 is embedded in the first positioning groove 24, and the second positioning block 12 is embedded in the second positioning groove 22, so as to determine and limit the relative position of the collection module 10 and the processing module 20 when fixed, and prevent the two from being relatively displaced due to improper operation during work.

[0030] It should be understood that the above description and the drawings only show the shapes of part of the positioning blocks and the positioning grooves, and the actual shapes and the number of the positioning blocks and the positioning grooves can be determined according to the specific production conditions, and the embodiment is not limited.

[0031] Preferably, a first nameplate attachment area 19 is provided on the collection module 10, and a second nameplate attachment area 28 is provided on the processing module 20, which can be used to display the name of the module, the sampling rate, the current voltage, and other information.

[0032] After the first magnetic member 18 and the second magnetic member 27 are fixed in the first limiting groove 11 and the second limiting groove 21 respectively, a PVC sticker 30 can be attached to the surface of the collection module 10 and the processing module 20 respectively, which is used to cover the magnetic members, but the positioning block, the positioning hole and the nameplate attachment area are exposed.

[0033] Preferably, in order to facilitate disassembly and picking up, at least one of the collection module 10 and the processing module 20 is provided with a handle for gripping, so as to provide a gripping point for the operator and prevent being pinched during operation. For example, in Figure 2 or 3, the collection module 10 is provided with a handle 13 which protrudes from both sides of the collection module 10 and extends outward (perpendicular to the connection direction of the collection module 10 and the processing module 20). Of course, the handle structure can also be provided on the processing module 20, or both the collection module 10 and the processing module 20, and the present embodiment is not limited.

[0034] Preferably, in order to improve ease of use, a magic tape 14 is also fixed at the bottom of the collection module 10, which can temporarily fix the collection module 10 and the processing module 20 on the patient's body after being bound with a matching magic tape band (not shown in the figure). Of course, in addition to the above fixing method, other fixing methods such as buttons or buckles can also be selected, and the present embodiment is not limited.

[0035] Further, a third limiting groove 16 for fixing the magic tape 14 is provided at the bottom of the collection module 10, and the magic tape 14 is fixed in the third limiting groove 16, which is used to improve the stability after long-term use and prevent the magic tape 14 from shifting or even falling off.

[0036] In an embodiment, the processing module 20 adopts a separate power supply mode, that is, a battery compartment 23 is provided, and the internal battery is a rechargeable battery or a dry battery which is convenient to replace, and the present embodiment is not limited. The processing module 20 is also provided with an openable compartment door 26 for the battery compartment 23, so as to improve the stability of the built-in battery and prevent the battery from falling off.

[0037] Further, a plurality of expansion interfaces 25 are also provided on the side wall of the processing module 20, which can be inserted into a data storage card or externally connected to other auxiliary equipment, so that the processing module 20 has high flexibility and expandability.

[0038] For example, Figure 3As shown, a plurality of holes are arranged in the first positioning groove 24, and a spring needle male end (not shown) for data transmission is installed inside the processing module 20 and protrudes out through the holes. An opening is arranged on the top of the first positioning block 17, and a female end (not shown) matching the spring needle male end is arranged inside the collection module 10 and protrudes out of the opening on the top of the first positioning block 17. After the collection module 10 and the processing module 20 are fixed, the spring needle male end is inserted into the female end and the connection is completed, so that the detection data can be transmitted to the processing module 20. The cooperation of the first positioning groove 24 and the first positioning block 17 and the cooperation of the holes and the opening on the top of the first positioning block 17 can ensure that the spring needle male end is correctly inserted into the female end, preventing the spring needle male end from being bent or even broken.

[0039] As shown in the drawings, the collection module 10 is connected to the processing module 20 through the first positioning block 17 and the first positioning groove 24. Figure 2 As shown, a window 15 is arranged on the side wall of the collection module 10, and a connector (not shown) for connecting with different electrode EEG caps is arranged inside the collection module 10 and protrudes out of the window 15, so as to facilitate the connection of the EEG cap.
