Description

Technical Field

[0001] This application relates to the field of electroencephalogram technology, and particularly to an electroencephalogram acquisition device with a packaging board. Background Art

[0002] When the brain is in neural activity, weak electric field fluctuations will be generated. When tens of thousands of neurons are active simultaneously, the electric field will generate rhythmic fluctuations, which can be measured from the scalp, namely electroencephalogram (EEG). With the continuous development of medical electronics, EEG has gradually attracted people's attention. EEG signals contain rich information about brain activities. As a special and complex bioelectrical signal, it reflects the functional state of the brain and is an important means for brain research, physiological research, and clinical diagnosis of brain diseases. Detecting these EEG activities through certain methods can effectively extract the rich information hidden in the human brain. Analyzing this information helps to deeply understand the functions of the brain and can also detect abnormal brain lesions in time to diagnose brain diseases. Therefore, the extraction of EEG signals has very important clinical significance.

[0003] Most of the existing EEG extraction devices are set in the form of a cap structure and need to wrap the human head during use. Reference can be made to an EEG collector with the publication number CN104665826A; it is provided with an elastic arc plate, and a plurality of anti-slip bumps are arranged in a dot matrix on the inner surface of the elastic arc plate. EEG acquisition electrodes are installed at the center position of the inner surface of the elastic arc plate and on the ear clips. However, in order to adapt to the head circumferences of different users, the arc plate of this device is set as a deformable elastic structure. However, with the increase in the number of uses, the elastic arc plate undergoes deformation for a long time and is easily beyond the elastic limit; once it exceeds the elastic limit, the elastic arc plate will not return to its original state by itself; resulting in the phenomenon of loose clamping and the acquisition electrodes being unable to fully fit the human skin.

Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0033] Figure 1 Front view of an electroencephalogram acquisition device with a packaging board showing an embodiment of the present application; Figure 2 Rear view of an electroencephalogram acquisition device with a packaging board showing an embodiment of the present application; Figure 3 Shows the main body structure diagram of the acquisition device of an embodiment of the present application. As Figure 1 With Figure 3 Shown, the electroencephalogram acquisition device with a packaging board includes: a base tape 100, an acquisition device, and a packaging board 500; the acquisition device includes: a brow center electrode 310, two postauricular electrodes 410, and two frontal electrodes 210; a first mounting portion 300 is provided in the middle of the base tape 100, and the brow center electrode 310 is disposed on the first mounting portion 300; two second mounting portions 400 are respectively provided at both ends of the base tape 100; the two postauricular electrodes 410 are respectively disposed on the two second mounting portions 400; two third mounting portions 200 are provided on the base tape 100, and the two third mounting portions 200 are respectively disposed between the first mounting portion 300 and the two second mounting portions 400, and the two frontal electrodes 210 are respectively disposed on the two third mounting portions 200; a taking portion 420 protrudes from the second mounting portion 400; a first relief groove 220 is formed in the third mounting portion 200; an adhesive layer is provided on one side of the first mounting portion 300 connecting the brow center electrode 310, one side of the second mounting portion 400 connecting the postauricular electrode 410, and one side of the third mounting portion 200 connecting the frontal electrode 210; the packaging board 500 is provided with a first mounting groove 510 and two second mounting grooves 530; the first mounting groove 510 and the two second mounting grooves 530 are respectively located on opposite sides of the packaging board 500; the first mounting groove 510 is adapted to place the first mounting portion 300 and the two third mounting portions 200; the two second mounting grooves 530 are adapted to place the two second mounting portions 400.

[0034] Here, it should be noted that the base tape 100 is suitable for being wound around the human head. The first mounting portion 300 located in the middle of the base tape 100 is suitable for mounting the mid-brow electrode 310, and the mid-brow electrode 310 is suitable for collecting the electroencephalogram signals at the mid-brow of the human head. The second mounting portions 400 located at both ends of the base tape 100 are suitable for mounting two post-auricular electrodes 410, and the two post-auricular electrodes 410 are suitable for collecting the electroencephalogram signals behind the left and right ears of the human body respectively. The third mounting portion 200 located on the base tape 100 is suitable for mounting two frontal electrodes 210, and the two frontal electrodes 210 are suitable for collecting the electroencephalogram signals at the left and right fronts of the human body respectively. On the side of the first mounting portion 300, the second mounting portion 400, and the third mounting portion 200 for connecting the electrodes, there is an adhesive layer. The adhesive layer can not only fix the electrodes but also be pasted on the human skin, so as to paste each electrode at different positions on the human brain. The protruding taking portion 420 of the second mounting portion 400 is beneficial to the pasting efficiency of the second mounting portion 400, thereby improving the convenience of taking and placing the post-auricular electrode 410. Since the forehead part of the human body has a curvature, the first relief groove 220 of the third mounting portion 200 is suitable for shrinking when the third mounting portion 200 is pasted on the forehead, reducing the gap between the third mounting portion 200 and the forehead, and making the third mounting portion 200 more conformably pasted on the forehead. The packaging board 500 is suitable for placing the acquisition device and storing and protecting the acquisition device. In this application, the form of pasting is adopted to fix multiple electrodes. Under the action of the base tape 100 connecting the multiple electrodes, the multiple electrodes can be worn and disassembled simultaneously. The overall structure is simple, the assembly is convenient, the adaptability is high, no pre-assembly adjustment is required, the pasting is firm, and the stability of the electroencephalogram acquisition process can be effectively ensured.

[0035] Here, it should be noted that the main body of the base tape 100 is in a strip structure. The base tape 100 uses a flexible substrate, which is not only light in weight, high in reliability, but also strong in deformation ability and can be folded. At the same time, there are five wires on the base tape 100. These five wires are made of silver chloride paste through screen printing technology and have relatively stable conductivity. The output ends of the mid-brow electrode 310, the two post-auricular electrodes 410, and the two frontal electrodes 210 are respectively electrically connected to the five wires on the base tape 100 to realize data transmission. The base tape 100 and the five wires together form a flexible printed circuit board, which can not only be wound around the human head but also realize the output of the collected signals.

[0036] In a possible implementation, the two second mounting portions 400 are symmetrically arranged with the first mounting portion 300 as the center, and the two third mounting portions 200 are symmetrically arranged with the first mounting portion 300 as the center. The length from the center eyebrow electrode 310 to the two rear ear electrodes 410 is the same, and the length from the center eyebrow electrode 310 to the two frontal electrodes 210 is the same. The symmetrical arrangement can ensure that the two rear ear electrodes 410 are placed at the same positions behind the two ears, and the two frontal electrodes 210 are placed at symmetric positions on the forehead, thereby ensuring the accuracy of electroencephalogram signal acquisition.

[0037] In a possible implementation, the main bodies of the first mounting portion 300 and the third mounting portion 200 are both hexagonal structures, and the base material strip 100, the first mounting portion 300, the second mounting portion 400, and the third mounting portion 200 are integrally formed. The center eyebrow electrode 310 is disposed at the center of the first mounting portion 300; the rear ear electrode 410 is disposed at the center of the second mounting portion 400, and the frontal electrode 210 is disposed at the center of the third mounting portion 200.

[0038] In a possible implementation, the main body of the first relief groove 220 is in the shape of a crescent groove structure. As Figure 3 shown, the first relief groove 220 of the third mounting portion 200 is opened beside the frontal electrode 210, and the curved end of the crescent groove structure protrudes outward. At the same time, the first relief groove 220 of the other third mounting portion 200 is also disposed beside the frontal electrode 210, and the first relief grooves 220 of the two third mounting portions 200 are symmetrically arranged with each other.

[0039] In a possible implementation, a second relief groove 211 is formed in the side wall of the third mounting portion 200; the main body of the second relief groove 211 is in the shape of an arc groove structure. It should be noted that the second relief groove 211 is set to be arc-shaped to make way for the user's eyebrows, avoiding the third mounting portion 200 being directly pasted onto the forehead eyebrows, resulting in the frontal electrode 210 being not firmly pasted.

[0040] In a possible implementation, as Figure 3 shown, the gripping portion 420 and the base material strip 100 are respectively located at both ends of the second mounting portion 400; the main body of the gripping portion 420 is in the shape of a triangular sheet structure. It should be noted that the gripping portion 420 and the second mounting portion 400 are integrally formed.

[0041] It should be noted that the shape of the adhesive layer of the first mounting portion 300 is the same as that of the first mounting portion 300. One side of the brow center electrode 310 is adhered to the adhesive layer of the first mounting portion 300, and a sponge is adhered to the other side of the brow center electrode 310; the shape of the adhesive layer of the third mounting portion 200 is the same as that of the third mounting portion 200. One side of the frontal electrode 210 is adhered to the adhesive layer of the third mounting portion 200, and a sponge is also adhered to the other side of the frontal electrode 210; the shape of the adhesive layer of the second mounting portion 400 is the same as that of the second mounting portion 400. One side of the postauricular electrode 410 is adhered to the adhesive layer of the second mounting portion 400, and a sponge is also adhered to the other side of the postauricular electrode 410. Here, it should be noted that the gripping portion 420 of the second mounting portion 400 is not provided with an adhesive layer for the convenience of manual operation. The function of the sponges adhered to the brow center electrode 310, the two frontal electrodes 210, and the two postauricular electrodes 410 is to adhere the conductive paste.

[0042] Furthermore, the adhesive layers of the first mounting portion 300, the second mounting portion 400, and the third mounting portion 200 are all made of foam adhesive tape.

[0043] In a possible implementation, the first mounting portion 300 is provided with a connecting band 320. The connecting band 320 is integrally formed with the first mounting portion 300 of the base material band 100, and is suitable for integrating the five wires on the base material band 100 on the connecting band 320 to facilitate data output. Furthermore, one ends of the wires of the two postauricular electrodes 410 pass through the adhesive layer and are respectively connected to the two postauricular electrodes 410. The other ends of the wires of the two postauricular electrodes 410 extend along the base material band 100 to the third mounting portion 200 and the first mounting portion 300, and finally extend from the first mounting portion 300 to the connecting band 320; one ends of the wires of the two frontal electrodes 210 pass through the adhesive layer and are respectively connected to the two frontal electrodes 210. The other ends of the wires of the two frontal electrodes 210 extend along the base material band 100 to the first mounting portion 300, and finally extend from the first mounting portion 300 to the connecting band 320; one end of the wire of the brow center electrode 310 passes through the adhesive layer and is connected to the brow center electrode 310, and the other end of the wire of the brow center electrode 310 directly extends from the first mounting portion 300 to the connecting band 320. Thus, the wires of the five electrodes are integrated on the connecting band 320. One end of the connecting band 320 is provided with a connector, and the five wires are electrically connected to the connector, which is suitable for data transmission with an external acquisition device through the connector.

[0044] In a possible implementation, the main body of the packaging board 500 is in a rectangular plate-like structure. It should be noted that a packaging board 500 is proposed for the convenience of storing the acquisition device of the present application. When the acquisition device does not need to work, the acquisition device is wound and collected on the packaging board 500 to store the acquisition device.

[0045] Further, a first installation groove 510 is formed on one side of the packaging board 500. The main body of the first installation groove 510 is a rectangular groove structure. A first gasket 511 adapted thereto is laid in the first installation groove 510. The shape of the first gasket 511 is the same as that of the first installation groove 510. The first gasket 511 is provided with three electrode holes. As Figure 2 shown, since the two frontal electrodes 210 and the glabella electrode 310 protrude relative to the adhesive layer, when the two third installation parts 200 and the middle first installation part 300 are simultaneously placed into the first installation groove 510, the two frontal electrodes 210 and the glabella electrode 310 penetrate into the three electrode holes of the first gasket 511. At this time, the adhesive layers of the two third installation parts 200 and the adhesive layer of the first installation part 300 can be completely attached to the first gasket 511. Under the isolation of the first gasket 511, it can effectively ensure that the adhesive layer is not exposed outside, avoiding the reduction of the adhesiveness of the adhesive layer and affecting the pasting firmness.

[0046] Further, two second installation grooves 530 are formed on the opposite side of the packaging board 500. The structures of the two second installation grooves 530 are the same and are symmetrically arranged on the packaging board 500. The second installation part 400 is adapted to be placed in the second installation groove 530. A second gasket 531 adapted thereto is laid in the second installation groove 530. The shape of the second gasket 531 is the same as that of the second installation groove 530. The second gasket 531 is provided with an electrode hole. As Figure 1 shown, since the two postauricular electrodes 410 protrude relative to the adhesive layer, when the two second installation parts 400 are placed into the two second installation grooves 530, the two postauricular electrodes 410 penetrate into the electrode hole of the second gasket 531. At this time, the adhesive layers of the two second installation parts 400 are completely attached to the second gasket 531. Under the isolation of the second gasket 531, it can effectively ensure that the adhesive layer is not exposed outside, avoiding the reduction of the adhesiveness of the adhesive layer and affecting the pasting firmness.

[0047] In a possible implementation manner, the packaging board 500 is provided with a clamping part; the clamping part and the second installation groove 530 are located on the same side of the packaging board 500 and the clamping part is located between the two second installation grooves 530; the clamping part is adapted to clamp the connecting belt 320. As Figure 2 shown, the clamping part includes: two clamping plates 520. The two clamping plates 520 protrude from one side of the packaging board 500. A clamping groove is formed in the middle of the two clamping plates 520. The connecting belt 320 can be embedded in the clamping groove. Under the clamping action of the two clamping plates 520, the fixing stability of the connecting belt 320 can be ensured.

[0048] In a possible implementation, the packaging board 500 is provided with three limiting grooves 540, and the three limiting grooves 540 are respectively formed on three side edges of the packaging board 500. The base material tape 100 and the connecting tape 320 are adapted to be wound around the packaging board 500 through the limiting grooves 540. Here, it should be noted that since the length of the base material tape 100 is relatively long, in order to reduce the size of the packaging board 500, the base material tape 100 needs to be wound around the edge of the packaging board 500, such as Figure 1 and Figure 2 shown, the two frontal electrodes 210 and the mid-brow electrode 310 are placed on the same side of the packaging board 500, and the base material tapes 100 on both sides of the two third mounting portions 200 are wound around both sides of the packaging board 500, so that the post-auricular electrodes 410 can be placed on the other side of the packaging board 500. The setting of the limiting grooves 540 is adapted to limit the base material tape 100 so that it is stably wound around the packaging board 500. At the same time, since the first mounting groove 510 and the clamping portion are also respectively arranged on the opposite sides of the packaging board 500, the connecting tape 320 is also wound around the side edge of the packaging board 500 to enable the connecting tape 320 to be inserted into the clamping portion on the other side. The limiting grooves 540 are adapted to limit the connecting tape 320 so that it is stably wound around the packaging board 500.

Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
