These sensors are cumbersome to operate and are not flexible enough for rapid experiments or temporary monitoring. Although disposable EEG sensors avoid the trouble of repeated use, they are slow to fix to the human body, time-consuming, and not firmly fixed, which can easily cause signal distortion or sensor detachment. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Example 1

[0027] The present invention provides a disposable electroencephalogram sensor that can be quickly fixed, such as Figure 1-Figure 6 As shown, it includes: a sensor body 1, a protective strip 2 is bonded to the top of the sensor body 1, a plurality of positioning holes 3 are equidistantly opened inside the sensor body 1, adhesive sheets 4 are respectively clamped and installed at the internal positions of the plurality of positioning holes 3 inside the sensor body 1, a chip 5 is fixedly installed at one end of the sensor body 1, a protective cover 6 is installed on the outside of the chip 5, a rectangular rod 8 is symmetrically integrally formed at one end of the chip 5 at the bottom end of the sensor body 1, a plastic strip 7 is clamped and installed inside the rectangular rod 8, and the plastic strip 7 is integrally formed at the bottom end of the sensor body 1, and a connecting belt 17 is connected between one ends of the two plastic strips 7.

[0028] like Figures 1 to 4As shown, a rectangular hole is provided at one end of the rectangular rod 8, and a rectangular strip is integrally formed at one end of the plastic strip 7 at the inner position of the rectangular hole, and rounded corners are provided on both sides of the rectangular strip, which is used for connecting the plastic strip 7 and the rectangular rod 8, thereby changing the difficulty of connecting the plastic strip 7 and the rectangular rod 8, and enabling the plastic strip 7 and the rectangular rod 8 to be fixed to each other. The shape of the adhesive sheet 4 is circular, and a card block is provided on the back of the adhesive sheet 4, which is card-connected and installed inside the sensor body 1, which is convenient for installing the adhesive sheet 4, changing the difficulty of installing the adhesive sheet 4, and facilitating the disassembly and replacement of the adhesive sheet 4;

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, the bottom end of the protective cover 6 is rotatably connected to a rotating disk 9, and a connecting wire 10 is wound around the outside of the rotating disk 9. Both ends of the connecting wire 10 are connected to curved strips 11. The opposite surfaces of the two curved strips 11 are integrally formed with protrusions 12, which are used for the relative movement of the two curved strips 11, and the relative movement difficulty of the two curved strips 11 is changed. A chamfer is provided on one end surface of the protrusion 12. The length and width of the protrusion 12 are relative to the length and width of the rectangular hole. When the protrusion 12 is displaced, it is convenient to squeeze the rectangular strip of the plastic strip 7, so that the rectangular strip and the rectangular rod 8 are separated. The opposite surfaces of the curved strip 11 are fixedly installed with sleeves 13, and the piston rod 14 is slidably connected inside the sleeve 13. A rectangular block 15 is fixedly installed at one end of the piston rod 14, and the rectangular block 15 is integrally formed at the bottom end of the protective cover 6. When the curved bar 11 moves, it drives the piston rod 14 to move. When the piston rod 14 moves, negative pressure is generated inside the sleeve 13. The negative pressure is used to facilitate the resetting of the piston rod 14. The piston rod 14 is T-shaped, and a sealing ring is sleeved on the outside of the piston rod 14 to increase the sealing between the piston rod 14 and the sleeve 13 to prevent gas leakage. A friction block 16 is fixedly installed at one end of one of the curved bars 11, and the friction block 16 is slidably connected to the inside of the protective cover 6. A fitting groove is opened on one side of the inner wall of the protective cover 6 at a position corresponding to one end of the friction block 16. The friction block 16 facilitates the displacement of the curved bar 11, which changes the displacement difficulty of the curved bar 11. The friction block 16 is movably connected with a piston column 18 up and down. The piston column 18 moves toward the inside of the friction block 16, so that the pressure inside the friction block 16 changes. At this time, the pressure facilitates driving the friction block 16 to reset. A plug rod 19 is embedded in the top of the piston column 18, and a circular hole is opened at the top of the protective cover 6 to facilitate the connection between the piston column 18 and the protective cover 6, thereby achieving the purpose of fixing the friction block 16 and preventing the friction block 16 from being displaced.

[0030] Working principle: During the actual use of the device, the user pulls the protective cover 6 to separate the protective cover 6 and the chip 5, and then pulls the protective strip 2 to separate the protective strip 2 and the sensor body 1, and then fits the sensor body 1 to the patient. At this time, multiple adhesive sheets 4 are bonded to different positions of the patient's head, which increases the bonding strength between the sensor body 1 and the patient, prevents the sensor body 1 from separating from the patient, and prevents displacement during exercise or head movement. It can also significantly reduce the probability of the sensor falling off during patient exercise, ensuring that the sensor works stably for a long time.

[0031] When the sensor body 1 is finished being used, the personnel pulls the connecting belt 17, and the connecting belt 17 moves to simultaneously drive the two plastic strips 7 to bend, so that the rectangular plate and the rectangular rod 8 inside the plastic strip 7 are separated, and then the personnel disassemble the chip 5. The whole disassembly process is simple and clear, and no complicated mechanical structure is required, so as to achieve the purpose of easy disassembly, thereby reducing the difficulty of use, and the chip 5 can be quickly disassembled for easy recycling and reuse, thereby reducing the generation of electronic product waste and reducing pollution to the environment;

[0032] The above-mentioned disassembly process requires the personnel's hands to contact the chip 5. When the personnel install the protective cover 6 and the chip 5, the personnel pushes the friction block 16 inside the protective cover 6. When the friction block 16 moves, it drives one of the curved strips 11 to move. When one of the curved strips 11 moves, it drives the connecting wire 10 to move. When the connecting wire 10 moves, it drives the rotating disk 9 to rotate. At this time, the connecting wire 10 drives another curved strip 11 to move. When the two curved strips 11 move synchronously relative to each other, they drive the piston rod 14 to move inside the sleeve 13, so that negative pressure is generated inside the sleeve 13. The negative pressure is used to facilitate the reset of the curved strip 11. When the friction block 1 6 moves to a predetermined position, at this time, the pressure inside the friction block 16 drives the piston column 18 to move, so that the piston column 18 drives the insertion rod 19 to enter the positioning hole of the protective cover 6, and at the same time, the two curved strips 11 are clamped on the outside of the chip 5, and at this time, the protrusion 12 drives the plastic strip 7 and the rectangular rod 8 to separate, and the protrusion 12 is inside the rectangular rod 8, and then the personnel takes the protective cover 6, and the protective cover 6 drives the chip 5 and the sensor body 1 to be disassembled synchronously, so that the disassembled chip 5 can be protected to prevent the personnel's hands from contacting the chip 5, which causes the surface of the chip 5 to be corroded, thereby extending the life of the chip 5.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
