[0002] Electroencephalogram can understand the brain function state by measuring spontaneous rhythmic bioelectric activities. It is the most objective examination method for epilepsy diagnosis and classification, a commonly used neuroelectrophysiological examination method, and an examination technology for brain bioelectric activities. During the examination, electrodes are placed at appropriate positions and recorded in a quiet, eyes-closed, awake or sleeping state. Induced tests such as eyes open / close, hyperventilation, flash stimulation, sleep, and drugs are often used to improve the positive rate of electroencephalogram examination. The examination is mainly used for the diagnosis, classification, and lesion localization of epilepsy, and has auxiliary diagnostic value for differentiating organic or functional brain lesions, diffuse or localized damage, and encephalopathies caused by various reasons such as encephalitis, poisoning, and metabolism. Therefore, it plays an important role in daily life.

[0003] The existing electroencephalogram instruments have the following problems:

[0004] 1. Currently, when examining a patient's electroencephalogram, generally, electrode paste is applied on the electrode pads and fixed on the patient's scalp with medical tape. When the examination is completed and the electrode pads are removed from the patient's scalp, due to the strong adhesion of the tape, the patient's hair will be pulled, causing pain to the patient and also resulting in hair tearing and shedding, leading to poor comfort during the examination.

[0005] 2. Currently, the electrode pad assembly and the connecting wire are fixed, and the connecting wire cannot be separately wound and placed. It is very easy for the connecting wire to be scattered randomly, and it takes a lot of time to organize the wire during the next use, resulting in poor convenience of use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the utility model in detail with reference to the embodiments:

[0026] Embodiment 1

[0027] As Figures 1-5As shown, the utility model provides an electroencephalogram electrode protection and fixing cap, which includes a fixing cap main body 1. A elastic band 2 is fixedly connected to the lower surface of the fixing cap main body 1. An electrode sheet assembly 4 is arranged inside the fixing cap main body 1. An electric plug 3 is arranged on the upper surface of the fixing cap main body 1. The electrode sheet assembly 4 includes a fixing piece 41 fixedly connected inside the fixing cap main body 1. A fixing column 42 is fixedly connected to the lower surface of the fixing piece 41. A movable column 43 is slidably connected inside the fixing column 42. The other end of the movable column 43 is fixedly connected to an electrode soft sheet 44. The electrode soft sheet 44 is adapted to the shape of the head. A compression spring 45 is sleeved on the surface of the fixing column 42. Two ends of the compression spring 45 are respectively fixedly connected to the fixing piece 41 and the electrode soft sheet 44. The electrode soft sheet 44 is electrically connected to the fixing piece 41. The fixing piece 41 is electrically connected to the fixing plug 31.

[0028] In this embodiment, when an electrocardiogram measurement needs to be performed on a patient, the fixing cap main body 1 is put on the patient's head, and the elastic band 2 is pulled to the patient's chin to fix the fixing cap main body 1. In order to avoid the situation that the electrode sheet assembly 4 is not in stable contact with the patient's head, after putting on the fixing cap main body 1, the head will squeeze the electrode soft sheet 44. The electrode soft sheet 44 will move upward under the squeeze. The upward movement of the electrode soft sheet 44 drives the movable column 43 to move upward together. The movable column 43 slides inside the fixing column 42. When the electrode soft sheet 44 moves upward, it will compress the compression spring 45. When the compression spring 45 is compressed, it will generate a downward thrust. The thrust generated by the compression spring 45 squeezes the electrode soft sheet 44 downward, so that the electrode soft sheet 44 is in full contact with the head. The electrode soft sheet 44 is made of a soft material and can be deformed according to the shape of the head, so that it can better contact the head and improves the applicability of the device.

[0029] Embodiment 2

[0030] As Figures 1-5 Shown, on the basis of Embodiment 1, the utility model provides a technical solution: Preferably, the electric plug 3 includes a fixing plug 31 fixedly connected to the upper surface of the fixing cap main body 1. A metal pin 32 is fixedly connected inside the fixing plug 31. Limiting plates 33 are fixedly connected on both sides of the metal pin 32 inside the fixing plug 31. A movable plug 34 is inserted inside the fixing plug 31. A limiting groove 35 is arranged on the surface of the movable plug 34. The limiting plates 33 are adapted to the limiting groove 35. One end of the movable plug 34 is fixedly connected to a fixing plate 36. A wire 37 is fixedly connected to the side surface of the fixing plate 36. A metal pin hole 38 is arranged inside the movable plug 34. The metal pin hole 38 is adapted to the metal pin 32. The metal pin 32 is electrically connected to the fixing plug 31. The metal pin hole 38 is electrically connected to the wire 37.

[0031] In this embodiment, after putting on the fixing cap body 1, insert the connecting wire into the electrode sheet assembly 4, and connect the other end to the instrument. Hold the fixing plate 36, align the movable plug 34 with the fixed plug 31. Through the limiting plate 33 and the limiting groove 35, the fixed plug 31 and the movable plug 34 can be completely aligned, preventing the metal needle 32 from being bent or even broken after not being inserted into the metal needle hole 38. After alignment, insert the metal needle 32 into the metal needle hole 38. After insertion, the insertion depth can be controlled by the fixing plate 36 to prevent over-insertion. At the same time, the fixing plate 36 protrudes from the upper surface of the fixed plug 31, which is also convenient for pulling out. After the connection is completed, data is transmitted to the instrument through the wire 37. A plurality of electrode sheet assemblies 4 are fixed on the surface of the fixing cap body 1, and can be selected to be inserted into the appropriate electrode sheet assembly 4 according to the shape requirements of different patients' heads to meet the needs of different operations. After use, pull out the fixing plate 36 from the inside of the fixed plug 31, and the wire can be sorted out separately, which is convenient for next use and improves the convenience of the device.

[0032] Next, specifically describe the working principle of the electroencephalogram electrode protection fixing cap.

[0033] As Figures 1-5 shown, put the fixing cap body 1 on the patient's head, pull the elastic band 2, and pull the elastic band 2 to the patient's chin to fix the fixing cap body 1. In order to avoid the situation that the electrode sheet assembly 4 is not in stable contact with the patient's head, after putting on the fixing cap body 1, the head will squeeze the electrode soft sheet 44. The electrode soft sheet 44 will move upward when being squeezed. The electrode soft sheet 44 moving upward drives the movable column 43 to move upward together. The movable column 43 slides inside the fixed column 42. When the electrode soft sheet 44 moves upward, it will compress the extrusion spring 45. When the extrusion spring 45 is compressed, it will generate a downward thrust. The thrust generated by the extrusion spring 45 squeezes the electrode soft sheet 44 downward, so that the electrode soft sheet 44 is in full contact with the head. The electrode soft sheet 44 is made of soft material and can deform according to the head shape, enabling it to better contact the head. Hold the fixing plate 36, align the movable plug 34 with the fixed plug 31. Through the limiting plate 33 and the limiting groove 35, the fixed plug 31 and the movable plug 34 can be completely aligned, preventing the metal needle 32 from being bent or even broken after not being inserted into the metal needle hole 38. After alignment, insert the metal needle 32 into the metal needle hole 38. After insertion, the insertion depth can be controlled by the fixing plate 36 to prevent over-insertion. At the same time, the fixing plate 36 protrudes from the upper surface of the fixed plug 31, which is also convenient for pulling out. After the connection is completed, data is transmitted to the instrument through the wire 37. A plurality of electrode sheet assemblies 4 are fixed on the surface of the fixing cap body 1, and can be selected to be inserted into the appropriate electrode sheet assembly 4 according to the shape requirements of different patients' heads to meet the needs of different operations. After use, pull out the fixing plate 36 from the inside of the fixed plug 31 for separate sorting.

However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and concept of the present utility model fall within the protection scope of the present utility model.
