Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to an intelligent wearable biological signal monitoring device. Background Art

[0002] The brain is composed of a large number of neurons. When the brain is active, a large number of neurons will send out electrical signals, which are called brain waves. It is a method of recording brain activity using electrical signal indicators.

A part of the deflation pipe 4155 is located inside the airbag pillow 3 and is connected to the airbag pillow 3.

[0037] The working principle of the present invention is as follows: when the biological monitoring device is turned on, the central processor 412 transmits a signal to the power supply 413, and the power supply 413 starts to supply power to the dual-axis motor 406, and the dual-axis motor 406 starts. The output shaft at one end of the dual-axis motor 406 drives the worm to rotate, and the worm drives the meshing worm gear to rotate, and the worm gear drives the upper tightening roller 401 to rotate, and the tightening roller 401 starts to tighten the headband 1, and the headband 1 is continuously wound on the tightening roller 401, and the spring pushes the push block in the direction of the tightening roller 401, and the push block slides in the slide groove, and the pressing roller 404 on the push block presses the headband 1 on the cylinder surface of the tightening roller 401 to ensure that the headband 1 fits the tightening roller 401. In the process of the headband 1 being wound on the tightening roller 401, the pressing roller 404 is subjected to the friction force of the headband 1, and the pressing roller 404 starts to rotate, and the rotation direction of the pressing roller 404 is opposite to the rotation direction of the tightening roller 401.

[0038] The other output shaft of the dual-axis motor 406 passes through the stable support frame 407 to drive the rotating rod 408 to rotate. The stable support frame 407 prevents the rotation of the rotating rod 408 from driving the output shaft to vibrate. The rotating rod 408 drives the piston to reciprocate in the air cylinder 409. A one-way valve is installed on the piston. When the piston slides toward the air inlet of the air cylinder 409, the one-way valve on the piston allows gas to pass through.

[0039] When the piston slides toward the air outlet of the air cylinder 409, the one-way valve is closed, and the piston presses the gas into the air pipe 410 through the air outlet of the air cylinder 409. The air cylinder 409 inflates the air into the airbag pillow 3 through the air pipe 410. A one-way valve is installed at the connection between the air pipe 410 and the airbag pillow 3 to ensure the air tightness of the airbag pillow 3.

[0040] The central processing unit 412 transmits an electrical signal to the power supply 413, and the power supply 413 supplies power to the semiconductor refrigeration device 414. The current flows from the N-type semiconductor to the metal wire, and then from the metal wire to the P-type semiconductor. The metal wire begins to absorb heat, and the temperature of the headband 1 begins to drop. The current flows through the P-type semiconductor to the metal sheet connected to the P-type semiconductor, and then flows through the metal sheet connected to the P-type semiconductor to the metal sheet connected to the N-type semiconductor, and then flows from the metal sheet connected to the N-type semiconductor to the N-type semiconductor, forming a loop. The two metal sheets dissipate heat. The two metal sheets are connected to the heat sink 411, and the heat sink 411 dissipates heat to ensure the normal operation of the semiconductor refrigeration device 414.

[0041] A torque sensor 405 is installed at the connection between the output shaft of the dual-axis motor 406 and the worm. When the torque sensor 405 detects the torque of the set value, it transmits an electrical signal to the central processor 412, and the central processor 412 transmits an electrical signal to the power supply 413. The power supply 413 stops supplying power to the dual-axis motor 406, tightening stops, and inflation stops. At this time, the user has finished wearing the device.

[0042] The central processing unit 412 transmits an electrical signal to the power supply 413, and the power supply 413 supplies power to the EEG sensor 2. The EEG sensor 2 starts to work, and the EEG sensor 2 transmits the collected data to the central processing unit 412 for processing to monitor the biological signal.

[0043] When the biological monitoring device is closed, the pressing rod 4151 is pressed, and the pressing rod 4151 moves downward to compress the pressing spring, so that the ratchet 402 and the pawl 403 are misaligned, the tightening roller 401 can rotate in the opposite direction, and the headband 1 can be released. The pressing rod 4151 drives the deflation slide bar 4152 to slide downward along the deflation slide groove, and drives the rotating connecting rod 4154 to move downward and rotate. The rotating connecting rod 4154 pushes another deflation slide bar 4152 to slide in the horizontal direction. The deflation slide bar 4152 sliding in the horizontal direction drives the deflation cover 4156 to separate from the deflation pipe 4155, and the airbag pillow 3 begins to deflate.

[0044] The central processing unit 412 transmits an electrical signal to the power supply 413 , and the power supply 413 stops supplying power to the EEG sensor 2 and the semiconductor refrigeration device 414 .
