Description

Technical Field

[0001] The invention relates to the field of brain magnetism detection, and in particular to a brain magnetism measuring chair. Background Art

[0002] Brain magnetometry technology is a completely non-invasive means of detecting brain signals. Its basic principle is to place extremely weak magnetic measurement sensors on the outside of the scalp to capture the weak magnetic field generated by the discharge of brain neurons. Currently, the existing brain magnetometry sensors are mainly based on the superconducting quantum interference device (SUQID) based on liquid helium superconducting technology and the optically pumped atomic magnetometer (OPM).

[0003] Since the SUQID magnetoencephalogram requires liquid helium to maintain the superconducting state, it has disadvantages such as high cost, large size, and expensive maintenance. Therefore, countries around the world are actively promoting the development of magnetoencephalograms based on atomic magnetometers.

[0004] Existing horizontal shielding tube magnetoencephalography instrument is as follows Figure 1 As shown in the figure, the subject lies flat on the bed and is pushed into the barrel. Due to the small diameter of the inner barrel, the subject has basically no space to move inside; the other vertical shielding barrel has basically the same disadvantages except for the posture change; specifically, the "seat system" of the horizontal shielding barrel magnetoencephalogram is just a bed, and the subject can only lie flat and the body can only remain fixed; the vertical shielding barrel just stands the bed upright, and the subject can only simply sit or stand with the body fixed.

[0005] Different examination postures of the human body have an impact on brain signals, so the MEG chair should have a multi-posture adjustment function to meet more task state requirements and ensure comfort during the experiment; due to the large size of the shielded room, in order to obtain better magnetic field parameter indicators in the target area, an active shimming coil system is generally added. The target area of ​​the system is directly related to the detection area of ​​the MEG chair.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] The magnetoencephalogram measuring chair of the present invention is suitable for the interior of a shielded room, which provides a shielded environment for the sensor to eliminate interference from the earth's magnetic field and the external magnetic field.

[0032] See also Figure 2 The magnetoencephalogram measurement chair of the present invention includes a chair structure 10, a shim coil system 20, a visual stimulation component 40, a position sensor 50, a pneumatic internal and external intercom component 60, a pneumatic auditory stimulation component 70 and a table top 80.

[0033] See also Figures 3 to 8 The seat structure 10 includes a cabin 11 and a seat body 12. The seat body 12 is rollably mounted on the cabin 11 to adjust the relative position of the seat body 12. The cabin 11 is used to integrate the visual stimulation component 40, the position sensor 50, the pneumatic internal and external intercom component 60 and the pneumatic auditory stimulation component 70. The top of the cabin 11 can also accommodate a measurement helmet, which is convenient for the storage and use of the measurement helmet. The seat body 12 is provided for the tester to sit on, which improves the tester's comfort. The seat body 12 can adjust the height and angle of the tester after sitting down, so that the tester's head is located in the measurement area 30, which improves the measurement accuracy and precision.

[0034] Specifically, the cabin 11 includes a main body 110, a cover plate 111, a support member 112, a headrest assembly 114, a slide rail 115 and a block 116. The main body 110 is roughly L-shaped. The cover plate 111 is movably mounted on the top of the main body 110 through the support member 112. The support member 112 is a hovering mechanism. When the cover plate 111 is opened upward, it can hover at any position. The support member 112 keeps the cover plate 111 and the main body 110 in an open state, which is convenient for taking and placing the measuring helmet. A receiving space 113 for storing the measuring helmet is formed between the cover plate 111 and the main body 110. The receiving space 113 is designed as a V-shaped structure. The concave part can be used for the routing of the sensor harness inside the helmet. The left and right sides of the bottom are provided with stop bars 1130. The stop bars 1130 are arc-shaped. The stop bars 1130 are used to limit the position of the helmet after it is placed to ensure the stability of the helmet assembly.

[0035] The headrest assembly 114 includes a headrest body 1140 and a headrest plate 1141 installed on the headrest body 1140. The headrest body 1140 is concave as a whole, and its appearance is adapted to the curved surface of the magnetoencephalography helmet. The surface of the headrest body 1140 is made of flexible material. After opening the headrest plate 1141, the rotation of the headrest assembly 114 can be adjusted through the internal adjustment mechanism. Its function is to adjust the headrest assembly 114 to a suitable angle according to the posture of the seat body 12 below. After wearing the magnetoencephalography helmet, the test subject can comfortably lean on the headrest assembly 114, achieving: 1. The overall posture of the test subject is comfortable; 2. The concave design of the headrest assembly 114 can effectively fix the helmet and restrain the shaking of the helmet to achieve a better measurement state; 3. The concave area is convenient for the wiring of the sensor harness inside the helmet to avoid damage to the sensor.

[0036] The slide rail 115 is disposed at the bottom of the main body 110 , and the roller 123 is located on the slide rail 115 , so that the seat body 12 can be adjusted in front and rear position relative to the cabin body 11 .

[0037] The clamping blocks 116 are located on both sides of the cabin 11, and are used to clamp the position sensor 50 and the pneumatic internal and external intercom assembly 60 to prevent the position sensor 50 and the pneumatic internal and external intercom assembly 60 from being unable to be placed when not in use.

[0038] The seat body 12 includes a seat cushion 120 , a backrest 121 , a base 122 , rollers 123 , a first driving rod 124 , a second driving rod 125 , a lifting driving structure 126 , a first rotating shaft 127 , a second rotating shaft 128 and a slide slot 129 .

[0039] The base 122 includes a base body 1221, a footrest 1222 and a mounting plate 1223. The base body 1221 is located at the bottom of the base 122. The roller 123 is installed on the bottom surface of the base body 1221. The lifting adjustment rod 1262 is installed on the upper surface of the base body 1221. An installation space is formed between the base body 1221 and the mounting plate 1223. The first driving rod 124, the second driving rod 125 and the lifting driving structure 126 are located in the installation space.

[0040] The seat cushion 120 is rotatably mounted on the top of the mounting plate 1223 via the first rotating shaft 127 .

[0041] The backrest 121 is rotatably mounted on the rear end of the mounting plate 1223 via the second rotating shaft 128, the slide groove 129 is provided on the seat cushion 120, and a sliding rod is provided on the backrest 121, which is located in the slide groove 129 and can slide along the slide groove 129, so that the backrest 121 can drive the seat cushion 120 to move, so that the backrest 121 and the seat cushion 120 maintain a fixed angle. The second rotating shaft 128 is located between the first rotating shaft 127 and the slide groove 129. The contact surfaces of the backrest 121 and the seat cushion 120 with the subject are wrapped with soft materials, so that the subject can maintain a comfortable state no matter what posture is adjusted.

[0042] The footrest 1222 is rotatably mounted on the front end of the mounting plate 1223. One end of the second driving rod 125 is connected to the footrest 1222, and the other end is connected to the mounting plate 1223. The second driving rod 125 drives the footrest 1222 to rotate relative to the mounting plate 1223, and adjusts the angle of the footrest 1222 so that the legrest 1222 can better support the testee's legs, especially in a semi-lying posture to ensure their comfort. The legrest 1222 is a double-layer design, which can be stretched and lengthened according to actual needs.

[0043] One end of the first driving rod 124 is rotatably connected to the backrest 121, and the other end is connected to the mounting plate 1223. The first driving rod 124 drives the backrest 121 to rotate relative to the mounting plate 1223 to adjust the pitch of the backrest 121. Figure 8 When a human body sits on the seat cushion 120, the length of the first driving rod 124 is adjusted to be reduced, which is equivalent to the backrest 121 falling backward, and the backrest 121 will rotate around the second rotation axis 128, and the backrest 121 slides in the slide groove 129 through the pin shaft to drive the seat cushion 120 downward, which is manifested as the seat cushion 120 rotating around the first rotation axis 127, and the seat cushion 120 is tilted up, so that the backrest 121 and the seat cushion 120 maintain a fixed angle.

[0044] The lifting drive structure 126 includes a lifting switch 1260, a lifting connecting rod 1261 and a lifting adjustment rod 1262. The lifting switch 1260 is installed on the end surface of the mounting plate 1223. The lifting connecting rod 1261 is connected to the lifting switch 1260 and the lifting adjustment rod 1262. The lifting connecting rod 1261 transmits the triggering of the lifting switch 1260 to the lifting adjustment rod 1262. One end of the lifting adjustment rod 1262 is fixed to the seat body 1221, and the other end cooperates with the mounting plate 1223. When the lifting adjustment rod 1262 is working, it drives the mounting plate 1223, the seat cushion 120 and the backrest 121 to move in the vertical direction to adjust the head position of the measured person so that the head of the measured person is located in the measurement area 30.

[0045] The shim coil system 20 is used to form a measurement area 30 to obtain better magnetic field parameter indicators. Specifically, the spacing between the shim coil system 20 is determined according to the design of the shielded room, preferably 2m. The shim coil system 20 constructs a 30cm (height direction, symmetrical up and down with 1.2m as the center) * 30cm (front and back direction, with the rear end surface of the headrest assembly 114 as the reference) * 40cm (left and right direction, symmetrical with the left and right centers of the headrest assembly 114 as the reference) cubic area as the core working area of ​​magnetoencephalography measurement, that is, the measurement area 30. The upper and lower, front and back center planes of the shim coil system 20 coincide with the working area.

[0046] The visual stimulation component 40 is used to display the picture of the magnetoencephalometric task paradigm. The visual stimulation component 40 includes a projector 41, a first reflector 42, a second reflector 43 and a display 44. The display 44 is installed at the front end of the seat, and its center height coincides with the headrest component 114 (i.e., preferably 1.2m). The projector 41 is placed outside the shielded room. When in use, the picture of the magnetoencephalometric task paradigm is projected and displayed on the display 44 through the first reflector 42 and the second reflector 43. The first reflector 42 and the second reflector 43 are optional solutions and may not be needed in actual use.

[0047] The position sensor 50 is used to obtain the position of the subject's head and sensor position information. The position sensor 50 is installed on the main body 110 .

[0048] The pneumatic internal and external intercom assembly 60 is used for communication between the internal and external subjects. When the shielding room is closed during the brain magnetometry measurement, there will be a sound insulation effect. In order to ensure the safety of the subjects, an intercom system needs to be added for real-time communication between the internal and external subjects. Because the brain magnetometry measurement environment must be guaranteed to be non-magnetic, the intercom system uses a pneumatic method. The pneumatic internal and external intercom assembly 60 is installed on the main body 110.

[0049] The pneumatic auditory stimulation assembly 70 is used for auditory experiments and is mounted on the main body 110 .

[0050] The table top 80 is detachably mounted on the main body 110 .

[0051] All wiring harnesses of the helmet assembly sensor, pneumatic auditory stimulation assembly 70, pneumatic internal and external intercom assembly 60, position sensor 50 and position sensor transmitter are routed inside the rear cover of the main body 110 and connected through the outlet. The outlet is symmetrically designed on the left and right of the seat rear cover and can be selected according to needs when in use.

[0052] When using the brain magnetism measurement chair, select the corresponding system according to the brain magnetism measurement task that needs to be performed (for example, for visual experiments, enable the visual stimulation component 40, use the pneumatic auditory stimulation component 70 for auditory experiments, and install the table board 80 for other sensory experiments. The above equipment can be used in any combination). After the subject enters and sits on the brain magnetism chair, he wears the brain magnetism measurement helmet: open the cover 111 on the receiving space 113, remove the brain magnetism helmet and put it on the subject. After the helmet is put on, turn on the position sensor transmitter, and use the position sensor 50 to obtain the subject's head position and sensor position information.

[0053] Then, a desired posture is selected (e.g., upright sitting posture, reclining sitting posture, etc.) to adjust the angle of the backrest 121 of the seat body 12, the height of the seat cushion 120 is adjusted according to the height of the subject, and the seat body 12 is moved forward and backward, the subject's head is adjusted to the measuring area 30 at the headrest assembly 114, and the height and angle of the headrest assembly 114 are adjusted so that the subject's head can rest naturally and comfortably on the headrest assembly 114. Then the test is started.

[0054] Compared with the OPM magnetoencephalogram, the magnetoencephalogram device based on the shielded cylinder in the prior art has a single posture for the subjects (basically only lying flat), poor comfort and can only remain motionless, and too few magnetoencephalogram measurement paradigms can be carried out. The magnetoencephalogram measurement chair of the present application can realize magnetoencephalogram measurement in various postures of subjects of different heights, and with a wearable magnetoencephalogram helmet, the subject's head can be allowed to move within a certain range (especially when the subject is a child, the elderly, patients with ADHD or other special groups, the equipment is more user-friendly and can carry out more tasks). At the same time, this seat system is equipped with a variety of auxiliary equipment, with a higher degree of integration, which can better meet the needs of magnetoencephalogram signal measurement in various functional scenarios.

[0055] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
