Description

Technical Field

[0001] The present application relates to the field of electrode technology, and in particular to a brain wave acquisition device with detachable electrodes. Background Art

[0002] Traditional contact electrodes are fixed on measuring equipment. When the contact electrodes are oxidized and corroded for a long time, the contact resistance of the contact electrodes increases, which can easily cause inaccurate measurement of the equipment. More seriously, it causes Joule heating effect around the contact electrodes, increasing the temperature rise at the contact point, causing unpredictable dangers.

[0003] Most of the existing brain wave acquisition devices are set up with an integrated structure. Reference may be made to a pre-warning and alarm device based on brain waves and three-axis acceleration sensors with publication number CN210244579U, which includes an integrated head-mounted device and a monitoring and recording platform in a ring shape. The integrated head-mounted device includes a brain wave sensor, a three-axis acceleration sensor, a microprocessor I, a microprocessor II, a feedback output device, an action electrode, a reference electrode and a first wireless transceiver. The monitoring and recording platform is a monitoring device including a second wireless transceiver and a display. After the integrated head-mounted device is worn on the human head, the collection, processing and closed feedback of brain wave signals can be realized. The integrated head-mounted device has good portability, but with long-term use, the electrodes are oxidized and corroded. Once the electrodes fail, since the electrodes are fixedly set on the integrated head-mounted device, the electrodes cannot be repaired or replaced, and the entire device can only be scrapped, increasing the cost.

[0004] Therefore, how to disassemble the contact electrode has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the present application proposes an electrode-detachable EEG acquisition device, which is suitable for disassembling electrodes.

[0006] According to one aspect of the present application, there is provided a brain wave acquisition device with detachable electrodes, comprising: an elastic assembly belt, a detachable connection component and an acquisition device;

[0007] The acquisition device includes: an eyebrow electrode and two frontal electrodes, the eyebrow electrode and the two frontal electrodes are both provided with a mounting shell, and the detection ends of the eyebrow electrode and the two frontal electrodes protrude out of the mounting shell;

[0008] The three mounting shells are connected in sequence, and a connecting belt is provided between each two adjacent mounting shells; and the mounting shell of the eyebrow center electrode is located between the mounting shells of the two forehead electrodes;

[0009] The elastic assembly band is provided with a connecting portion, and the mounting shell of the eyebrow electrode is detachably connected to the connecting portion of the elastic assembly band by disassembling the connecting assembly.

[0010] In a possible implementation, the disassembly connection assembly includes: matching buckles and slots; the buckles are arranged on the mounting shell of the eyebrow electrode; and the slots are arranged on the connecting portion.

[0011] In a possible implementation, three detachable connection components are provided, one of which is located on one side of the mounting shell of the brow electrode, and the other two detachable connection components are located on the other side of the mounting shell of the brow electrode.

[0012] In one possible implementation, any mounting shell includes a first shell and a second shell that are buckled relative to each other, and the brow electrode or two forehead electrodes are arranged between the first shell and the second shell; the first shell is provided with a through hole, and the detection end of the brow electrode or the two forehead electrodes protrudes out of the mounting shell through the through hole.

[0013] In one possible implementation, the buckle is disposed on the second shell.

[0014] In a possible implementation, a support portion is provided on a side of the mounting shell of the frontal electrode facing the elastic mounting band, which is suitable for adjusting the distance between the frontal electrode and the elastic mounting band.

[0015] In a possible implementation manner, the supporting portion is a sponge.

[0016] In a possible implementation, a flexible circuit board is further included, and two frontal electrodes are respectively arranged at two ends of the flexible circuit board, and the eyebrow electrode is connected to the flexible circuit board and is located between the two frontal electrodes.

[0017] In one possible implementation, the flexible circuit board is attached to one side of the connecting strip.

[0018] Beneficial effects of this application

The present application proposes an electrode detachable EEG acquisition device, including: an elastic mounting belt 400, a disassembly connection component and an acquisition device; the acquisition device includes: an eyebrow electrode 100 and two frontal electrodes 200, the eyebrow electrode 100 and the two frontal electrodes 200 are both provided with a mounting shell, and the detection ends of the eyebrow electrode 100 and the two frontal electrodes 200 protrude from the mounting shell; the three mounting shells are connected in sequence, and a connecting belt 420 is provided between each two adjacent mounting shells; and the mounting shell 110 of the eyebrow electrode 100 is located in the middle of the mounting shells 210 of the two frontal electrodes 200, and the elastic mounting belt 400 is provided with a connecting portion 410, and the mounting shell 110 of the eyebrow electrode 100 is detachably connected to the connecting portion 410 of the elastic mounting belt 400 by disassembling the connecting component.

[0040] It should be noted here that the acquisition equipment includes: an eyebrow electrode 100 and two frontal electrodes 200, which are suitable for collecting weak electrical signals generated at the eyebrow and forehead of the human brain. The eyebrow electrode 100 and the two frontal electrodes 200 are both provided with a mounting shell, which provides physical protection for the eyebrow electrode 100 and the two frontal electrodes 200 to avoid damage to the electrodes due to collision or friction during use. The detection ends of the eyebrow electrode 100 and the two frontal electrodes 200 protrude from the mounting shell, which can ensure that the eyebrow electrode 100 and the frontal electrode 200 are in direct contact with the skin, reducing interference from other substances, thereby improving the accuracy of the acquisition.

[0041] A connecting belt 420 is provided between each two adjacent mounting shells; the connecting belt 420 connects each mounting shell together in sequence, thereby realizing the connection between the two frontal electrodes 200 and the brow electrode 100, ensuring the accuracy of the position of the acquisition device during wearing, and avoiding the problem of inaccurate acquisition caused by the movement of the acquisition device. The elastic assembly belt 400 is provided with a connecting portion 410, and the mounting shell 110 of the brow electrode 100 is detachably connected to the connecting portion 410 of the elastic assembly belt 400 by disassembling the connecting component. By setting up a disassembly connection component, when the acquisition device needs to be replaced, the mounting shell 110 of the brow electrode 100 is separated from the connecting portion 410 by disassembling the connecting component, thereby realizing the disassembly of the acquisition device, without disassembling the entire EEG acquisition device, saving maintenance time and cost. It should be pointed out here that the main body of the connecting belt 420 is a long strip structure, and preferably, the connecting belt 420 is made of a flexible material.

[0042] Further, such as Figure 2 As shown, the main parts of the brow electrode 100 and the two forehead electrodes 200 are both in a plate-like structure with protruding parts, and the protruding parts of the brow electrode 100 and the two forehead electrodes 200 form detection ends.

[0043] Preferably, the eyebrow electrode 100 and the two forehead electrodes 200 are made of copper material. The surfaces of the eyebrow electrode 100 and the two forehead electrodes 200 are coated with a gold plating layer.

[0044] In one possible implementation, Figures 4 to 8 As shown, any mounting shell includes a first shell and a second shell that are buckled relative to each other, and the brow electrode 100 or two forehead electrodes 200 are arranged between the first shell and the second shell; the first shell is provided with a through hole, and the detection end of the brow electrode 100 or the two forehead electrodes 200 protrudes out of the mounting shell through the through hole.

[0045] It should be noted here that if Figure 5 , Figure 8 As shown, the mounting shell includes a mounting shell 210 for two frontal electrodes 200 and a mounting shell 110 for the brow electrode 100. The mounting shells 210 of the two frontal electrodes 200 each include a first shell 211 of the frontal electrode 200 and a second shell 212 of the frontal electrode 200 that are relatively buckled. The first shell 211 of the frontal electrode 200 and the second shell 212 of the frontal electrode 200 that are relatively buckled are fixedly connected by dispensing glue. Compared with other fixing methods, dispensing glue is easier to implement and control. The two frontal electrodes 200 are arranged between the first shell 211 of the frontal electrode 200 and the second shell 212 of the frontal electrode 200, so that the two frontal electrodes 200 are limited in the mounting shell 210 of the frontal electrode 200. The mounting shell 210 of the frontal electrode 200 can effectively reduce the contact area between the frontal electrode 200 and the air, avoid oxidation and corrosion caused by the contact between the frontal electrode 200 and the air, and extend the service life of the electrode. The first shell 211 of the frontal electrode 200 is provided with a first through hole 215, which matches the outer contour of the detection ends of the two frontal electrodes 200. The two frontal electrodes 200 protrude from the mounting shell 210 of the frontal electrode 200 through the first through hole 215. The detection ends of the two frontal electrodes 200 directly contact the measured parts, thereby reducing interference in the signal transmission process and improving the accuracy of the acquisition.

[0046] Further, such as Figure 5 , Figure 8As shown, the mounting shell 110 of the eyebrow electrode 100 includes a first shell 111 of the eyebrow electrode 100 and a second shell 112 of the eyebrow electrode 100 that are relatively buckled, and the first shell 111 of the eyebrow electrode 100 and the second shell 112 of the eyebrow electrode 100 that are relatively buckled are fixedly connected by dispensing, and the eyebrow electrode 100 is arranged between the first shell 111 of the eyebrow electrode 100 and the second shell 112 of the eyebrow electrode 100, so as to limit the eyebrow electrode 100 in the mounting shell of the eyebrow electrode 100. 110, the mounting shell 110 of the eyebrow electrode 100 can effectively reduce the contact area between the eyebrow electrode 100 and the air, and a second through hole 115 is opened on the first shell 111 of the eyebrow electrode 100, and the second through hole 115 matches the outer contour of the detection end of the eyebrow electrode 100. The eyebrow electrode 100 protrudes from the mounting shell 110 of the eyebrow electrode 100 through the second through hole 115, and the detection end of the eyebrow electrode 100 directly contacts the measured part, which reduces the interference in the signal transmission process and improves the accuracy of the acquisition.

[0047] In a possible implementation, the mounting shell 110 of the eyebrow electrode 100 is detachably connected to the connecting portion 410 of the elastic mounting band 400 by disassembling the connecting assembly. Figure 4 , Fig. 9 As shown, the disassembly connection assembly includes: matching buckles 310 and slots 320; the buckle 310 is arranged on the mounting shell 110 of the brow electrode 100; the slot 320 is opened on the connecting part 410, which is suitable for detachably connecting the collection device to the connecting part 410.

[0048] It should be noted that a buckle 310 is provided on the side of the mounting shell 110 of the eyebrow electrode 100 facing the elastic mounting band 400. Figure 3 As shown, the main body of the buckle 310 is an "L"-shaped plate structure, and one end of the buckle 310 is fixedly connected to the mounting shell 110 of the eyebrow electrode 100. Correspondingly, the connecting portion 410 is provided with a slot 320, and the slot 320 is a strip-shaped groove structure. The buckle 310 and the slot 320 match each other, and the buckle 310 is suitable for probing into the groove of the slot 320. It should be noted that when the buckle 310 is embedded in the slot 320, one side of the buckle 310 is slightly bent, so that the buckle 310 can be smoothly connected to the inside of the slot 320, thereby firmly locking the buckle 310 in the slot 320. When the buckle 310 is pulled out, the buckle 310 is also slightly bent to disengage from the slot 320, so that the buckle 310 is separated from the slot 320, thereby pulling the buckle 310 out of the slot 320. By setting matching buckles 310 and slots 320, users can easily install or remove the acquisition device on the connecting part 410, simplifying the disassembly process and improving the convenience of use. Preferably, the buckle 310 can be made of plastic with a small deformation ability.

[0049] In one possible implementation, Figure 4 As shown, the buckle 310 is arranged on the second shell 112 of the eyebrow electrode 100. It should be noted here that since the eyebrow electrode 100 is located between the two forehead electrodes 200, the second shell 112 of the eyebrow electrode 100 is located at the center position, which can optimize the force distribution. The setting position of the buckle 310 can ensure that after being connected and fixed with the connecting part 410, the acquisition device can remain stable, avoiding the distortion and deformation of the acquisition device due to uneven force.

[0050] In one possible implementation, Figure 4 As shown, there are three detachable connection components, one of which is located on one side of the mounting shell 110 of the eyebrow electrode 100 , and the other two detachable connection components are located on the other side of the mounting shell 110 of the eyebrow electrode 100 .

[0051] It should be noted here that by setting up three disassembly components, the connection between the mounting shell 110 of the eyebrow electrode 100 and the connecting part 410 is more stable. One of the disassembly connection components is located on one side of the mounting shell 110 of the eyebrow electrode 100, and the other two disassembly connection components are located on the other side of the mounting shell 110 of the eyebrow electrode 100. When the mounting shell 110 of the eyebrow electrode 100 is subjected to external force, the three disassembly components can jointly bear the force, reduce the pressure of the single-point connection, and extend the service life.

[0052] In one possible implementation, Figure 6 As shown, a wrench 113 is fixedly provided on one side of the second shell 112 of the eyebrow electrode 100. It should be noted here that when the acquisition device is disassembled, by turning the wrench 113, the wrench 113 drives one side of the buckle 310 on the second mounting shell 112 of the eyebrow electrode 100 to be slightly bent, and one side of the buckle 310 is disengaged from the slot 320 after being slightly bent, thereby pulling the buckle 310 out of the slot 320. By providing the wrench 113, the user can easily install the acquisition device on the connecting part 410 or remove it from the connecting part 410 by turning the wrench 113, thereby simplifying the disassembly process.

[0053] Further, such as Figure 4As shown, a guide protrusion 114 is provided on the side of the second shell 112 of the eyebrow electrode 100 facing the elastic mounting band 400, and correspondingly, a positioning groove (not shown in the figure) matching the guide protrusion 114 is provided on the connecting portion 410, and the input end of the gold finger 610 passes through the guide protrusion 114 on the second shell 112 of the eyebrow electrode 100, and both ends are respectively located on the inner and outer sides of the mounting shell 110 of the eyebrow electrode 100. By providing the positioning groove and the guide protrusion 114, it is ensured that the output end of the gold finger 610 is accurately positioned when connected to the input end of the connecting portion 410, thereby improving the accuracy of the connection and avoiding displacement or loosening of the gold finger 610 during use, thereby ensuring the stability of the connection.

[0054] In one possible implementation, Figure 1 As shown, a support portion 500 is provided on the side of the mounting shell 210 of the frontal electrode 200 facing the elastic mounting band 400, which is suitable for adjusting the distance between the frontal electrode 200 and the elastic mounting band 400. It should be noted here that the main body of the support portion 500 is a rectangular parallelepiped structure, and two support portions 500 are provided. One side of the two support portions 500 is fixedly connected to the two frontal electrodes 200 respectively, and the side of the two support portions 500 facing away from the two frontal electrodes 200 is in contact with the elastic mounting band 400. By providing the support portion 500, the two frontal electrodes 200 are closely attached to the skin, thereby ensuring the continuity and stability of the data collected by the two frontal electrodes 200.

[0055] Furthermore, one side of the two support parts 500 is fixedly connected to the two frontal electrodes 200 by glue dispensing. Preferably, the support part 500 is a sponge.

[0056] In one possible implementation, Fig.10 As shown, it also includes a flexible circuit board 600, two frontal electrodes 200 are respectively arranged at the two ends of the flexible circuit board 600, and the eyebrow electrode 100 is connected to the flexible circuit board 600 and is located in the middle of the two frontal electrodes 200. It should be noted here that the flexible circuit board 600 is suitable for adapting to the shape of the head curve due to its flexible characteristics, ensuring that the eyebrow electrode 100 and the two frontal electrodes 200 fit tightly with the head, and the two frontal electrodes 200 are arranged at the two ends of the flexible circuit board 600, and the output ends of the two frontal electrodes 200 are connected to the input end of the flexible circuit board 600, the eyebrow electrode 100 is connected to the flexible circuit board 600 and is located in the middle of the flexible circuit board 600, and the output end of the eyebrow electrode 100 is connected to the input end of the flexible circuit board 600. The flexible circuit board 600 passes through the mounting shell 110 of the eyebrow electrode 100 and penetrates into the mounting shell 210 of the two frontal electrodes 200. It should be further noted that, as Fig.10As shown, the flexible circuit board 600 is provided with three collecting ends, which are respectively located at the two ends and the middle of the flexible circuit board. The two collecting ends at the two ends respectively penetrate into the mounting shells 210 of the two frontal electrodes 200, and are connected to the side of the two frontal electrodes 200 located inside the mounting shells 210 of the frontal electrodes 200; at the same time, since the flexible circuit board 600 passes through the mounting shell 110 of the brow electrode 100, the collecting end in the middle of the flexible circuit board 600 is located inside the mounting shell 110 of the brow electrode 100, and is connected to the side of the brow electrode 100 located inside the mounting shell 110 of the brow electrode 100. Such a design reduces the connection lines and interfaces between the brow electrode 100, the two frontal electrodes 200 and the flexible circuit board 600, making the overall structure of the collecting device more compact and reducing the manufacturing cost. The input end of the flexible circuit board 600 respectively penetrates into the recessed grooves of the brow electrode 100 and the two forehead electrodes 200 and fits tightly with the inner walls of the recessed grooves, thereby ensuring that the output ends of the brow electrode 100 and the two forehead electrodes 200 are stably connected to the input end of the flexible circuit board 600.

[0057] Further, such as Fig.10 As shown, the main body of the flexible circuit board 600 is a strip-shaped structure, and the two ends of the flexible circuit board 600 are respectively inserted into the recessed grooves of the two frontal electrodes 200 and are tightly fitted with the recessed grooves of the two frontal electrodes 200. The output ends of the two frontal electrodes 200 are located at a corner close to the brow electrode 100. The input ends of the flexible circuit board 600 at both ends are respectively connected to the output ends of the two frontal electrodes 200 by welding. The input end of the flexible circuit board 600 located between the two frontal electrodes 200 is inserted into the recessed groove of the brow electrode 100. The output end of the brow electrode 100 is located at a corner of the brow electrode 100. The output end of the brow electrode 100 is connected to the output end of the two frontal electrodes 200 by welding. The input end of the flexible circuit board 600 is connected between the eyebrows 200, and the output end of the flexible circuit board 600 is connected to the input end of the connecting part 410 on the elastic mounting band 400 through the gold finger 610. The input end of the gold finger 610 passes through the second shell 112 of the eyebrow electrode 100 and is connected to the output end of the flexible circuit board 600 located in the recessed groove of the eyebrow electrode 100. The output end of the gold finger 610 is arranged on the same side as the buckle 310. When the buckle 310 is embedded in the slot 320 of the connecting part 410, the output end of the gold finger 610 is connected to the input end of the connecting part 410, thereby transmitting the brain waves collected by the eyebrow electrode 100 and the two frontal electrodes 200 to the connecting part 410 through the gold finger 610.

[0058] In one possible implementation, Figure 4As shown, the flexible circuit board 600 is attached to one side of the connecting belt 420, and the flexible circuit board 600 is attached to the side of the connecting belt 420 facing the elastic assembly belt 400. The flexible circuit board 600 can bend with the bending of the connecting belt 420, thereby avoiding the connection between the eyebrow electrode 100 and the two forehead electrodes 200 and the flexible circuit board 600 from being damaged, thereby ensuring the stability of the overall structure.
