Description

Technical Field

[0001] This utility model relates to the field of head positioning device technology, and in particular to a head positioning device for electroencephalogram (EEG) examination. Background Technology

[0002] An electroencephalogram (EEG) is a diagnostic tool used to record the electrical activity of the brain. By placing electrodes on the scalp, an EEG captures the electrical signals generated by neuronal activity. This examination is commonly used to diagnose and evaluate a variety of neurological disorders. During an EEG examination, patients usually need to remain relaxed and avoid movement as much as possible. The examination typically lasts from 30 minutes to 1 hour, and in some cases, monitoring may need to be performed while the patient is asleep.

[0003] During an electroencephalogram (EEG) examination, it is necessary to maintain stability as much as possible to avoid shaking during the examination. However, since the examination takes a certain amount of time, many patients cannot remain still in one position for a long time, which can affect the examination results. In addition, after lying down before the examination, it is inconvenient for patients to raise their heads, making it difficult to adjust the head position, which will affect the effectiveness of the device. Therefore, it is necessary to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a head positioning device for electroencephalography (EEG) examination.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A head positioning device for electroencephalography (EEG) examination includes a base plate and an arc-shaped placement plate. A connecting seat is fixedly connected to the center of the top of the base plate. The top of the connecting seat is annular. Arc-shaped plates are fixedly connected to both sides of the top of the connecting seat. The tops of the two arc-shaped plates are also annular. The arc-shaped placement plate is slidably connected to the top of the connecting seat and between the two arc-shaped plates. Side plates are fixedly connected to both symmetrical sides of the surface of the arc-shaped placement plate. The two side plates are slidably connected to the tops of the two arc-shaped plates respectively. A sliding mechanism for sliding the arc-shaped placement plate is provided inside the connecting seat. Positioning mechanisms are provided at both ends of the arc-shaped placement plate. The arc-shaped placement plate facilitates the placement of the head during use, and the angle between the arc-shaped placement plate and the head can be adjusted, thereby improving the effectiveness of the device. When the head is placed on the arc-shaped placement plate, the two arc-shaped rods will move closer to each other and rotate, facilitating head positioning.

[0007] Preferably, the sliding mechanism includes multiple rollers, which are rotatably connected to symmetrical sides of the surface of the arc-shaped placement plate. The multiple rollers are evenly distributed in a ring. Multiple fixed shafts are fixedly connected to both symmetrical sides of the surface of the arc-shaped placement plate. The multiple rollers are rotatably sleeved on the surfaces of the multiple fixed shafts. The multiple rollers roll on the top of the connecting seat. Arc-shaped grooves are opened on opposite sides of the two arc-shaped plates. The multiple rollers are respectively disposed inside the two arc-shaped grooves to reduce the resistance of the arc-shaped placement plate sliding and make it easier for the arc-shaped placement plate to slide on the connecting seat.

[0008] Furthermore, a connection port is provided at the top arc surface of the connecting seat, which communicates with the interior of the connecting seat. Two fixing blocks are fixedly connected to the bottom of the arc-shaped placement plate. A connection groove is provided through the surface of each of the two fixing blocks. Both fixing blocks are slidably connected to the interior of the connection port. A slider is horizontally slidably connected inside the connecting seat. The slider is vertically arranged and slidably connected between the two fixing blocks. The slider and the two fixing blocks cooperate with each other. A lead screw is rotatably connected inside the connecting seat. The lead screw is horizontally arranged, and its two ends are respectively rotatably sleeved on the connecting... Inside the seat, at both ends, a lead screw nut is fixedly connected to the center of the slider. The lead screw is rotatably sleeved inside the lead screw nut, and the lead screw nut cooperates with the lead screw. Inside the connecting seat, two slide rods are fixedly connected. Both slide rods are horizontally arranged. The slider is slidably sleeved on the outer surface of the two slide rods. Both ends of the surface of the connecting seat are rotatably connected to knobs. The two knobs are fixedly connected to the two ends of the lead screw. The lead screw passes through the two connecting grooves to restrict the slider to slide horizontally inside the connecting seat. The setting of two fixed blocks will drive the arc-shaped placement plate to slide.

[0009] Preferably, the positioning mechanism includes arc-shaped rods. Two arc-shaped rods are provided on both symmetrical sides of the arc-shaped placement plate. Each arc-shaped rod is rotatably connected to one end of the surface of the arc-shaped placement plate. Rotating shafts are fixedly connected to opposite sides of the bottom ends of the two arc-shaped rods. The two rotating shafts are rotatably fitted inside the two rotating grooves. Connecting rods are horizontally fixedly connected to opposite sides of the top ends of the two arc-shaped rods. Fixing plates are fixedly connected to the bottom ends of the two arc-shaped rods. The two fixing plates are respectively disposed at the bottom of the two side plates. A groove is provided on the top arc surface of each of the two side plates. There are two circular grooves, each with a through-hole. A movable rod is slidably fitted inside each of the two through-holes. A first pressure plate is fixedly connected to the top of each of the two movable rods, and the two first pressure plates respectively cooperate with the two circular grooves. A second pressure plate is fixedly connected to the bottom of each of the two movable rods, and the two second pressure plates are respectively positioned on top of two fixed plates. The two second pressure plates cooperate with the two fixed plates to restrict the downward sliding of the multiple first pressure plates. Therefore, during use, the downward sliding of the first pressure plates, connected by the fixed plates, will drive the arc-shaped rod to rotate.

[0010] Furthermore, a silicone pad is fixedly connected to the top of the arc-shaped placement plate. The silicone pad is made of transparent silicone and is used to protect the head area, thereby improving the comfort of the device.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When in use, the patient's head is placed on the arc-shaped placement plate. During the process, the patient's head will press down on the four first pressure plates, causing the four first pressure plates to slide into the four corresponding circular grooves. Through the connection of the four movable rods, the four second pressure plates will push the four fixed plates respectively, which will cause the four arc-shaped rods to rotate. The rotation of the four arc-shaped rods will then position the patient's head, preventing the patient's head from moving randomly.

[0013] 2. By manually rotating either of the two knobs, the lead screw can be rotated. With the cooperation of the lead screw nut, the slider will slide horizontally. During the sliding process, the slider will contact one of the fixed blocks and push one of the fixed blocks to slide. At this time, the arc-shaped placement plate will slide together. With the setting of multiple rollers, the arc-shaped placement plate will slide more smoothly. And the trajectory of the arc-shaped placement plate can be used to easily adjust the position of the patient's head, thereby improving the ease of use of the device. Attached Figure Description

[0025] In this invention, a connecting port 14 is provided at the top arc surface of the connecting seat 11, and the connecting port 14 is connected to the interior of the connecting seat 11. Two fixing blocks 28 are fixedly connected to the bottom of the arc-shaped placement plate 2, and a connecting groove 29 is provided through the surface of each fixing block 28.

The two second pressure plates 52 cooperate with the two fixed plates 32 respectively to restrict the downward sliding of the multiple first pressure plates 5. In use, the downward sliding of the first pressure plates 5, under the connection of the fixed plates 32, will drive the arc-shaped rod 3 to rotate.

[0027] In this invention, a silicone pad 21 is fixedly connected to the top of the arc-shaped placement plate 2. The silicone pad 21 is made of transparent silicone and is used to protect the head area, thereby improving the comfort of the device.

[0028] Working principle: When in use, the device needs to be installed on an EEG testing equipment. During use, the patient's head is placed on the arc-shaped placement plate 2. During the process, the patient's head presses down on the four first pressure plates 5, causing them to slide into the four corresponding circular grooves 23. Through the connection of the four movable rods 51, the four second pressure plates 52 push the four fixed plates 32 respectively, thus rotating the four arc-shaped rods 3. This rotation of the four arc-shaped rods 3 positions the patient's head, preventing it from moving arbitrarily. When the patient's head is in position... After placement, the screw 41 can be rotated manually by turning either of the two knobs 4. With the cooperation of the screw nut 43, the slider 42 will slide horizontally. During the sliding process, the slider 42 will contact one of the fixed blocks 28 and push one of the fixed blocks 28 to slide. At this time, the arc-shaped placement plate 2 will slide together. With the setting of multiple rollers 26, the arc-shaped placement plate 2 will slide more smoothly. The trajectory of the arc-shaped placement plate 2 can be used to adjust the position of the patient's head, thereby improving the ease of use of the device.
