Description

Technical Field

[0001] The present invention belongs to the technical field of electroencephalogram electrode sheets, and more specifically, particularly relates to a combined electroencephalogram electrode sheet. Background Art

[0002] Electroencephalogram (EEG) is a commonly used examination method in the diagnosis of neurological diseases. It evaluates brain function by recording the electrical activity of the cerebral cortex. Traditional EEG electrodes are mostly split and need to be pasted on the patient's scalp one by one when used. This is not only cumbersome to operate, but also easy to affect the test results due to loose pasting or inaccurate positioning. In addition, traditional electrodes are mostly reused, which poses a risk of cross-infection.

[0003] In recent years, with the continuous advancement of medical technology, disposable medical supplies have gradually gained attention due to their advantages such as ease of use and avoidance of cross-infection. However, most of the disposable EEG electrodes on the market are simply adhesive-based, which fails to effectively solve problems such as loose adhesion of electrodes and difficulty in adjusting their positions.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a combined electroencephalogram electrode sheet is provided, in order to achieve a more practical purpose. Summary of the invention

A servo motor 21 is fixed to the head, a threaded rod 22 is fixed to the power output end of the servo motor 21, a threaded sleeve block 23 is threadedly connected to the outer wall of the threaded rod 22, the threaded sleeve block 23 is movably connected to the first telescopic rod 30, a connecting block 40 is movably sleeved with a moving rod 42 on one side close to the middle of the top cover 10, an iron ball 43 is fixed to one side of the moving rod 42, an electromagnet 41 is fixed to the middle of the other side of the connecting block 40, a connecting plate 50 is detachably installed on the outer wall of the moving rod 42, an electrode sheet 60 is fixed to the middle of the bottom of the connecting plate 50, and a conductive glue 53 is provided at the bottom of one side of the connecting plate 50 close to the middle of the top cover 10.

[0037] Among them, a second hinge block 35 is fixed to the outer wall of the top cover 10, and the second hinge block 35 is rotatably connected to the middle part of the second sleeve rod 32, so that the second sleeve rod 32 can rotate outside the top cover 10, so that the bottom end position of the bottom second telescopic rod 33 is changed, thereby changing the position of the connecting block 40 and the electrode sheet 60, and a first hinge block 24 is fixed to the outer wall of the threaded sleeve block 23, and the first hinge block 24 is rotatably connected to the top end of the first telescopic rod 30, so that the angle between the first telescopic rod 30 and the threaded sleeve block 23 can be changed. When the threaded sleeve block 23 moves up and down, the first telescopic rod 30 is driven to telescope in the first sleeve rod 31, and the angle is changed at the same time. By controlling the servo motor 21 to drive the threaded rod 22 to rotate, the threaded sleeve block 23 is limited by the first telescopic rod 30 and will not rotate together, thereby making the threaded sleeve block 23 move up and down on the outer wall of the threaded rod 22.

[0038] Among them, the first telescopic rod 30 and the first set of rods 31 are arranged in a straight line, the second set of rods 32 and the second telescopic rod 33 are both arranged in an arc shape, and the second set of rods 32 and the second telescopic rod 33 have the same arc, so that the first telescopic rod 30 can be telescoped inside the first set of rods 31, and the second telescopic rod 33 can also be telescoped in an arc trajectory inside the second set of rods 32. The arc-shaped second set of rods 32 and the second telescopic rod 33 can better fit the outer contour of the user's head.

The multiple second sets of rods 32 and the second telescopic rods 33 can connect multiple connecting plates 50 and electrode sheets 60. When in use, the corresponding bottom of the second telescopic rod 33 can be selected for installation according to the position where the electrode sheet 60 needs to be installed.

[0040] Among them, a first ventilation hole 11 is opened through the top of the head cover 10, and a plurality of first ventilation holes 11 are arranged in a circle with equal intervals. A water-absorbent cotton 54 is fixed to one side of the connecting plate 50 near the bottom. The first ventilation hole 11 is used to dissipate heat from the user's head. At the same time, the water-absorbent cotton 54 can absorb sweat from the user's head, thereby increasing the user's comfort when using it.

[0041] Among them, a card block 13 is fixed at the bottom of the inner wall of the top cover 10, and the card block 13 is set in an L shape. A disposable alcohol cotton 14 is placed on the top of the card block 13. Before use, the disposable alcohol cotton 14 is placed on the top of the top cover 10 and located at the card block 13 to prevent it from falling. When the user uses it, the head and the top cover 10 are separated by the disposable alcohol cotton 14, which makes the top cover 10 more hygienic when used and reduces cross infection.

[0042] Among them, a groove 51 is opened through the top of one side of the connecting plate 50, and the diameter value of the groove 51 is adapted to the diameter value of the iron ball 43. A limiting block 52 is fixed on the side of the connecting plate 50 near the middle of the head cover 10. When in use, the connecting plate 50 is hung on the outer wall of the moving rod 42 by passing the groove 51 through the iron ball 43.

[0043] Among them, the limit block 52 is set in an arc shape and is installed obliquely with the connecting plate 50. There are multiple limit blocks 52, and the multiple limit blocks 52 are arranged equidistantly on the circumference. When the groove 51 passes through the iron ball 43, the limit block 52 will expand. The limit block 52 is made of plastic and has a certain elasticity. It will be displaced when passing through the iron ball 43 and will be reset after passing through the iron ball 43. The limit block 52 resists the iron ball 43 to prevent the connecting plate 50 from easily falling off the moving rod 42. After the connection is completed, the electromagnet 41 is energized to make the iron ball 43 move toward the electromagnet 41, and the limit block 52 is squeezed to make the connecting plate 50 fixed more tightly.

[0044] Among them, a conductive socket 61 is fixed in the middle of the electrode sheet 60 away from the limit block 52, and a limit ring 62 is fixed on one side of the outer wall of the conductive socket 61. When the electrode sheet 60 is connected to the power, the plug is inserted into the conductive socket 61, and the plug is tightly connected to the limit ring 62, so that the electrode sheet 60 is more convenient and quick to turn on and off.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In the present invention, before use, the disposable alcohol cotton 14 is first placed on the top of the head cover 10 and located at the block 13 to prevent it from falling. When the user uses it, the disposable alcohol cotton 14 is used to separate the head and the head cover 10, so that the head cover 10 is more hygienic when used and reduces cross infection. Then, the head cover 10 is worn on the head of the person to be tested, and the elastic band 12 is used to hang it on the chin of the person to be tested. Then, the servo motor 21 is controlled to rotate, driving the threaded rod 22 to rotate, and the threaded sleeve block 23 is limited by the first telescopic rod 30 and will not rotate together. The threaded sleeve 23 moves up and down in the outer wall of the threaded rod 22, driving the first telescopic rod 30 to telescope in the first sleeve 31. At the same time, the angle of the first sleeve 31 changes, driving the second sleeve 32 to rotate outside the head sleeve 10, so that the bottom end position of the second telescopic rod 33 at the bottom changes, thereby changing the position of the connecting block 40, so that the connecting block 40 fits the head of the person to be detected. According to the position where the electrode sheet 60 needs to be installed, the corresponding second telescopic rod 33 is selected for use, and by moving inside the second sleeve 32 The second telescopic rod 33 is used to change the position of the connecting block 40. After the position adjustment is completed, the second telescopic rod 33 is limited by tightening the limit bolt 34, and then the connecting plate 50 is installed, the groove 51 passes through the iron ball 43, and the connecting plate 50 is hung on the outer wall of the moving rod 42. When the groove 51 passes through the iron ball 43, the limit block 52 will expand. The limit block 52 is made of plastic and has a certain elasticity. It will be displaced when passing through the iron ball 43. After passing through the iron ball 43, it will reset. The limit block 52 resists the iron ball 43 to prevent the connecting plate 50 from moving from the moving rod 42 is easily detached. After the connection is completed, the electromagnet 41 is energized to make the iron ball 43 move toward the electromagnet 41, and the limit block 52 is squeezed to make the connecting plate 50 more tightly fixed. Finally, the plug is inserted into the conductive socket 61. At the same time, the plug is tightly connected to the limit ring 62, so that the electrode sheet 60 is more convenient and faster to be turned on and off. The first air vent 11 set during detection is used to dissipate heat to the user's head. At the same time, the absorbent cotton 54 set can absorb the sweat on the user's head, thereby increasing the comfort of the user when using it.
