Detailed implementation mode
[0039] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments:
[0040] As Figures 1 - 14 shown, an electroencephalogram (EEG) headband of the present invention includes a main skeleton 1. A secondary skeleton 2 is provided at the rear side of the main skeleton 1. Upper end caps 3 are integrally formed on both sides of the top of the main skeleton 1. A lower end cap 4 is integrally formed at the bottom of the secondary skeleton 2. The main skeleton 1 and the secondary skeleton 2, as well as the upper end caps 3 and the lower end caps 4, are all made of lightweight flexible materials, such as medical silicone materials, to reduce the weight of the components and the burden of wearing on the head. Moreover, the upper end caps 3, the lower end caps 4, the arc-shaped frame 6, and the extension frame 5 all adopt a hollow design, which is conducive to the flow supply of the gas source;
[0041] An extension frame 5 is integrally formed at the center of the bottom of the main skeleton 1, and an arc-shaped frame 6 is integrally formed on the front of the main skeleton 1. An inflation assembly is provided on the main skeleton 1 and the secondary skeleton 2 for use in conjunction with the upper end caps 3 and the lower end caps 4; the inflation assembly includes micro air pumps 71 connected to the two sides of the arc-shaped frame 6 close to the main skeleton 1, which closely fit a number of EEG electrodes to the head, improving the sensitivity and accuracy of the EEG electrodes in receiving brain signals, and replacing the manual operation of adjusting the tightness, saving time and effort, being convenient and fast. Moreover, adjustment assemblies are provided on both sides of the arc-shaped frame 6 for cooperation with the supply of the micro air pumps 71. The adjustment assemblies include arc-shaped sliding grooves 81 opened on both sides of the arc-shaped frame 6, which synchronously move two groups of high-precision micro cameras 86 inward to the eye area, and use the two groups of high-precision micro cameras 86 after reaching the position to capture the nystagmus images and frequencies of the eyes, achieving a high-precision detection effect for the eyes.
[0042] As Figures 5 - 11 shown, main air bags 72 are provided at the connection parts of the main skeleton 1 and the secondary skeleton 2 close to the micro air pumps 71, and main electrodes 73 are embedded inside the main air bags 72. Secondary air bags 74 are provided inside the upper end caps 3 and the lower end caps 4, and secondary electrodes 75 are embedded inside the secondary air bags 74. The main skeleton 1 and the secondary skeleton 2, as well as the upper end caps 3 and the lower end caps 4, are all provided with total channels 76 communicated and cooperated with the main air bags 72 and the secondary air bags 74. The gas source is supplied by two groups of micro air pumps 71 and is first inflated into the total channels 76 of the main skeleton 1 and the secondary skeleton 2, as well as the upper end caps 3 and the lower end caps 4 through the two groups of main air bags 72, and then transmitted to the secondary air bags 74 on the upper end caps 3 and the lower end caps 4, forcing the main air bags 72 and the secondary air bags 74 to expand after inflation, closely wearing on the head, meeting the wearing requirements of people with different head circumferences, and then closely fitting the main electrodes 73 and the secondary electrodes 75 to the head, improving the sensitivity and accuracy of the EEG electrodes in receiving brain signals;
[0043] On the outer sides of the upper end cap 3 and the lower end cap 4, there is a first micro pressure relief pipe 10 connected to the contraction and reset of the main airbag 72 and the auxiliary airbag 74. And a first micro pressure relief valve is provided on the first micro pressure relief pipe 10, which is convenient for relieving pressure and resetting the inflated main airbag 72 and auxiliary airbag 74, and is convenient for removing the main frame 1, the auxiliary frame 2 and their whole from the head.
[0044] On both sides of the inner cavity of the arc-shaped frame 6, there are telescopic airbags 82 slidably connected and cooperating with the micro air pump 71. And a reset elastic tendon 83 is embedded in the inner cavity of the telescopic airbag 82. The two micro air pumps 71 provide air source supply to the two telescopic airbags 82, forcing the two telescopic airbags 82 to expand inwards synchronously and stretching the two reset elastic tendons 83 accordingly. The inner ends of the telescopic airbags 82 are fixedly connected with sliding seats 84 slidably matched with the arc-shaped sliding grooves 81. And on the front surface of the sliding seat 84, there is a bracket 85 fixedly connected. At the bottom of the bracket 85, there is a high-precision micro camera 86 for detecting nystagmus. Through the two sliding seats 84, the high-precision micro cameras 86 on the two brackets 85 are driven to move inwards synchronously to the eye area, and the high-precision micro cameras 86 after reaching the position are used to capture the nystagmus pictures and frequencies, realizing the high-precision detection effect of the eyes;
[0045] The telescopic airbags 82 and the reset elastic tendons 83 are distributed symmetrically along the central axis of the arc-shaped frame 6, which is convenient for synchronously adjusting the two high-precision micro cameras 86. The brackets 85 and the high-precision micro cameras 86 are distributed in an axially symmetric and inclined state along the central axis of the arc-shaped frame 6, so that the two high-precision micro cameras 86 are accurately adjusted to the front of the eyes. And an arc-shaped design that fits the arc-shaped frame 6 is adopted, which is beneficial for the telescopic airbags 82 to expand and contract and reset along the shape of the arc-shaped frame 6. And a weight reduction groove is provided on the bracket 85 to reduce the weight of the bracket 85 and further reduce the wearing burden on the head. On both sides of the arc-shaped frame 6, there is a second micro pressure relief pipe 11 connected and cooperating with the telescopic airbag 82. And a second micro pressure relief valve is provided on the second micro pressure relief pipe 11, which is convenient for relieving pressure and resetting the inflated telescopic airbag 82;
[0046] On the inner side of the main frame 1 close to the extension frame 5, there is a patch type thermocouple temperature sensor 12 for real-time temperature monitoring of the forehead. And an arc-shaped sliding cavity 13 is opened in the inner cavity of the auxiliary frame 2 and is in a non-interconnected state with the total channel 76 to prevent the air source in the total channel 76 from leaking into the arc-shaped sliding cavity 13, resulting in insufficient air source. An arc-shaped elastic rod 14 is slidably connected to the inner side of the arc-shaped sliding cavity 13. And an elastic net 15 used in cooperation with the arc-shaped elastic rod 14 is fixedly connected to the inner side of the lower end cap 4, which plays an auxiliary tightening role for the head and improves the pre-fitting tightness between the main frame 1, the auxiliary frame 2 and the head.
[0047] Such as Figures 12 - 14As shown, during the monitoring of the head by the EEG headband, most of the time, only brain information can be captured and monitored, and the liquid medicine cannot be directly heated and then applied to the head, and the effect of assisting in relieving fatigue cannot be achieved. A hot compress component is provided on the extension frame 5, and the hot compress component includes a branch channel 91 opened between the main frame 1 and the extension frame 5. The air source supplied to the main channel 76 in the main frame 1 is conducted to the extension frame 5 through the branch channel 91. Miniature infrared heaters 92 are embedded on both sides of the front of the extension frame 5 to heat the air source conducted to the extension frame 5. In addition, an array of equalizing holes 93 are provided on the back side of the inner cavity of the extension frame 5, and a Velcro male surface 94 is provided on the outer side of the extension frame 5 near the equalizing holes 93, and a medicine storage core 95 is bonded to the inner side of the Velcro male surface 94 through a Velcro female surface 96. The heated air source in the extension frame 5 passes through the equalizing holes 93 for equalizing flow and is then conducted to the medicine storage core 95 area, thereby uniformly heating the medicine liquid in the medicine storage core 95, forcing the medicine liquid in the medicine storage core 95 to be infiltrated and coated on the forehead, thereby helping to relieve fatigue of the head and increasing the practical functional diversity of the EEG headband.
[0048] The working principle of an EEG headband is as follows: firstly, the main frame 1 and the auxiliary frame 2 are worn on the head, and the main airbags 72 and the auxiliary airbags 74 on the two sets of upper end covers 3 and the lower end covers 4 are respectively located at the front and back of the head, and the arc-shaped elastic rods 14 are preliminarily adjusted by contraction or expansion in the two sets of arc-shaped sliding cavities 13, and the elastic net 15 is elastically tightened to the two sets of lower end covers 4, so that the main frame 1 and the auxiliary frame 2 are closely attached to the back of the head, and the patch-type thermocouple temperature sensor 12 is attached to the top of the forehead, and the forehead temperature is monitored in real time;
[0049] When monitoring the head, the two groups of micro air pumps 71 are controlled to open and the air source is pre-conducted through the two groups of main air bags 72 to the main frame 1 and the auxiliary frame 2 and the total channel 76 in the two groups of upper end covers 3 and the lower end covers 4. With the coordination of the air source filling, the main air bags 72 and the auxiliary air bags 74 on the two groups of upper end covers 3 and the lower end covers 4 are forced to expand and change, and the two groups of main electrodes 73 and the auxiliary electrodes 75 are tightly fitted to the front and back brain positions, so as to capture the brain information in real time with high sensitivity and high precision. After the monitoring course expires, the first micro pressure relief valve on the first micro pressure relief tube 10 is controlled to open, and the air source in the total channel 76 of the two groups of upper end covers 3 and the lower end covers 4 is discharged by the first micro pressure relief tube 10. Under the reverse squeezing force of the head, the main air bags 72 and the auxiliary air bags 74 are forced to shrink to a deflated state, and after the two groups of main electrodes 73 and the auxiliary electrodes 75 are separated from the front and back brain positions, the main frame 1 and the auxiliary frame 2 are removed from the head as a whole.
[0050] When detecting the eyes, the two groups of micro air pumps 71 also supply the generated air source into the two telescopic air bags 82, forcing the two telescopic air bags 82 to expand synchronously and inwards along the shape of the arc-shaped frame 6. While stretching the two reset elastic bands 83 synchronously, the two telescopic air bags 82 drive the two sliding seats 84 to slide inwards synchronously in the arc-shaped sliding grooves 81. The two sliding seats 84 drive the two high-precision micro cameras 86 to move inwards synchronously through the two brackets 85 until the two high-precision micro cameras 86 move to the front of the eyes. Then, the two in-place high-precision micro cameras 86 monitor the tremors of the eye balls. After the eye detection is completed, the second micro pressure relief valve on the second micro pressure relief pipe 11 is controlled to open, and the air source in the two telescopic air bags 82 is discharged through the second micro pressure relief pipe 11. Under the elastic restoring force of the two reset elastic bands 83, the two telescopic air bags 82 are forced to contract and reset, and drive the two high-precision micro cameras 86 to move outwards to the initial position through the brackets 85 on the two sliding seats 84, and are located outside the eyes, without affecting the eye vision range.
[0051] When applying hot compress to the head, the air source generated by the two groups of micro air pumps 71 is supplied into the extension frame 5 through the main channel 76 in the main frame 1 and the branch channel 91, and the two groups of micro infrared heaters 92 are controlled to be turned on in advance to heat the air source supplied into the extension frame 5. The heated air source then reaches the area of the medicine storage core 95 evenly after being evenly distributed through the flow equalizing holes 93, heats and melts the liquid medicine stored in the medicine storage core 95, forcing the melted liquid medicine in the medicine storage core 95 to be evenly and comprehensively infiltrated and smeared on the forehead area, playing an auxiliary role in relieving fatigue of the head. After the liquid medicine in the medicine storage core 95 is infiltrated, a new medicine storage core 95 is replaced and adhered to the magic tape male surface 94 of the extension frame 5 through the magic tape female surface 96, and the head is continuously heated and medicated to relieve head fatigue.
[0052] It should be noted that the specific model specifications of the micro air pump 71, the electrode, the high-precision micro camera 86, the micro infrared heater 92, and the patch type thermocouple temperature sensor 12 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
[0053] The power supply circuits of the micro air pump 71, the electrode, the high-precision micro camera 86, the micro infrared heater 92, and the patch type thermocouple temperature sensor 12 are clear to those skilled in the art and will not be elaborated here.
