Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electroencephalogram (EEG) therapy device. Background Technology

[0002] Electroencephalography (EEG) is a medical device designed based on the principles of neuroelectrophysiology. It collects bioelectric signals from the brain through specific electrodes, analyzes and processes them, and then outputs electrical stimulation or electromagnetic fields of specific frequencies and intensities to act on the brain. It can be used to assist in the treatment of neurological diseases and memory loss, and has a positive effect on improving brain function and regulating mental state.

[0003] Most existing EEG therapy devices use adhesive bonding to connect the electrode pads to the head fixation ring, which makes disassembly and assembly inconvenient. When frequent electrode pad replacements are required, it is difficult to quickly remove and install the electrode pads from the fixation ring, affecting subsequent treatment procedures. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electroencephalogram (EEG) therapy device, which aims to improve the problem of inconvenient disassembly and assembly between the electrode pads and the head fixation ring, thus affecting subsequent treatment operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electroencephalogram (EEG) therapy device, comprising a connecting ring, two control slots inside the connecting ring, each control slot having a locking post inside, four limiting blocks slidably connected inside the connecting ring, control sliding posts fixedly connected to the tops of the four limiting blocks, two pressing plates fixedly connected to the tops of the four control sliding posts, a soft pad layer fixedly connected to the rear side of the connecting ring, a head fixing ring fixedly connected to the front side of the connecting ring, an elastic strip slidably connected inside the head fixing ring, an elasticating component inside the head fixing ring, a reset component on the surface of the control sliding posts, an adjustment component on the inner bottom wall of the elastic strip, and electrode sheet assemblies on adjacent sides of the two locking posts.

[0006] Preferably, the tensioning assembly includes a plurality of first limiting members, all of which are fixedly connected to the head fixing ring. A second limiting member is provided on the right side of the first limiting member on the left side. A control rod is fixedly connected to the rear side of the second limiting member. A reset slide column is slidably connected inside the second limiting member. A spring is fixedly connected to the bottom of the second limiting member.

[0007] Preferably, the reset assembly includes four reset slide plates, each of which is slidably connected to four control slide columns, each of which is fixedly connected to a connecting ring, and each of the four reset slide plates has a reset component fixedly connected to its bottom, and each of the four reset components is fixedly connected to a limit block.

[0008] Preferably, the adjustment assembly includes a rotating plate, which is rotatably connected to the tension strip. A control post is fixedly connected to the rear side of the rotating plate, and two limiting posts are fixedly connected to the inner bottom wall of the tension strip. The control post is located between the two limiting posts.

[0009] Preferably, the electrode pad assembly includes two electrode pad layers, both of which are fixedly connected to the retaining post. Electrode pad bodies are fixedly connected to adjacent sides of the two electrode pad layers. Both electrode pad bodies are located inside the soft pad layer. Electrotherapy device components are disposed at the bottom of the two electrode pad bodies.

[0010] Preferably, the first limiting member is a triangular block, the second limiting member is a triangular block, the first limiting member and the second limiting member have the same shape, and the first limiting member and the second limiting member are centrally symmetrical.

[0011] Preferably, each of the four reset slide plates has a groove inside, and the size of the groove inside each of the four reset slide plates is the same as the diameter of the four control slides. All four reset components are tension springs.

[0012] Preferably, the electrotherapy device assembly includes an electrotherapy device body, which is electrically connected to two electrode pad bodies, and an electrotherapy device control panel is provided on the top of the electrotherapy device body.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when it is necessary to disassemble the electrode pad, press the pressing plate to control the sliding column to drive the limiting block to slide inside the connecting ring, so that the limiting block cannot limit the locking column. At this time, the electrode pad body can be separated from the connecting ring, thereby removing the electrode pad body. This solves the problem that the inconvenience of disassembling and assembling the electrode pad and the head fixation ring affects subsequent treatment operations.

[0014] 2. In this utility model, the second limiting member moves between the first limiting member. During the movement, the first limiting member presses against the second limiting member, and the spring provides a rebound force to drive the second limiting member, so that the elastic strip can be fixed in a suitable position, which solves the problem that the head fixing ring cannot adapt to different head sizes.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an electroencephalogram (EEG) therapy device, comprising a connecting ring 1, two control slots 6 inside the connecting ring 1, each control slot 6 having a locking post 3 inside, four limiting blocks 2 slidably connected inside the connecting ring 1, control sliding posts 4 fixedly connected to the top of each of the four limiting blocks 2, two pressing plates 5 fixedly connected to the top of each of the four control sliding posts 4, a soft pad layer 14 fixedly connected to the rear side of the connecting ring 1, a head fixing ring 7 fixedly connected to the front side of the connecting ring 1, an elastic strip 8 slidably connected inside the head fixing ring 7, an elasticating component 10 inside the head fixing ring 7, a reset component 11 on the surface of the control sliding posts 4, an adjustment component 9 on the inner bottom wall of the elastic strip 8, and electrode sheet assemblies 12 on adjacent sides of each of the two locking posts 3.

[0019] Specifically, the shape and size of the two control slots 6 inside the connecting ring 1 match the locking post 3 to ensure that the locking post 3 can be placed stably in it. The locking post 3 is used to fix the electrode body 1201. Under normal use, the cooperation between the locking post 3 and the control slot 6, as well as the limiting effect of the limiting block 2, enable the electrode to be connected to the connecting ring 1, ensuring stable acquisition of EEG signals and effective transmission of treatment current. The control slide 4 transmits force to the limiting block 2. When the pressing plate 5 is subjected to external force, the control slide 4 transmits this external force to the limiting block 2, causing the limiting block 2 to slide within the connecting ring 1, thereby changing the limiting state of the locking post 3 and realizing the disassembly or installation of the electrode sheet. The pressing plate 5 provides the force point. Pressing the pressing plate 5 can drive the control slide 4 and the limiting block 2 to move. The soft padding layer 14 is in direct contact with the patient's head and is made of silicone. Silicone is soft and skin-friendly, which can improve the patient's comfort when wearing the EEG therapy device. The soft padding layer 14 can effectively buffer the pressure of the connecting ring 1 on the head and avoid discomfort caused by wearing it for a long time. The head fixation ring 7 is fixed to the patient's head to ensure that the entire EEG therapy device will not shift during the treatment. The elastic band 8 slides inside the head fixation ring 7. By pulling the elastic band, the circumference of the head fixation ring 7 can be changed to adapt to different patient head sizes.

[0020] Reference Figure 1 , Figure 3 and Figure 4 The tensioning assembly 10 includes multiple first limiting members 1001, all of which are fixedly connected to the head fixing ring 7. A second limiting member 1002 is provided on the right side of the first limiting member 1001 on the left side. A control rod 1003 is fixedly connected to the rear side of the second limiting member 1002. A reset slide column 1004 is slidably connected inside the second limiting member 1002. A spring 1005 is fixedly connected to the bottom of the second limiting member 1002.

[0021] Specifically, during the adjustment of the tightness of the head fixing ring 7, the first limiting member 1001 and the second limiting member 1002 provide positioning and limiting functions for the adjustment process. The control rod 1003 is fixedly connected to the rear side of the second limiting member 1002. When the control rod 1003 is pressed, the limitation of the first limiting member 1001 on the second limiting member 1002 can be released. The second limiting member 1002 can slide on the reset slide 1004, providing a guiding function for the movement of the second limiting member 1002. During the process of the second limiting member 1002 moving under the pressure of the first limiting member 1001, the reset slide 1004 ensures that the second limiting member 1002 moves in a predetermined direction, preventing it from deviating or shaking, thus ensuring the stability and reliability of the entire adjustment process. When the second limiting member 1002 moves, the spring 1005 will be compressed and store elastic potential energy. When the spring 1005 releases the stored elastic potential energy, it will drive the second limiting member 1002 to reset.

[0022] Reference Figure 2 The reset assembly 11 includes four reset slide plates 1101, each of which is slidably connected to four control slide columns 4. Each of the four reset slide plates 1101 is fixedly connected to a connecting ring 1. Each of the four reset slide plates 1101 has a reset component 1102 fixedly connected to its bottom, and each of the four reset components 1102 is fixedly connected to a limit block 2.

[0023] Specifically, the reset slide plate 1101 provides a sliding track for the control slide column 4. When the press plate 5 is pressed to move the control slide column 4, the control slide column 4 slides in the groove inside the reset slide plate 1101. The reset slide plate 1101 ensures that the control slide column 4 can only move in a specific direction, thus ensuring the stability of the entire operation process. The reset component 1102 is a tension spring. Its upper end is fixedly connected to the bottom of the reset slide plate 1101, and its lower end is connected to the limit block 2. When the pressing plate 5 is pressed to make the control slide 4 move the limit block 2, the tension spring is stretched. At this time, the tension spring stores elastic potential energy. When the external force is removed, that is, when the pressing plate 5 is released, the tension spring releases the stored elastic potential energy by its own elastic restoring force, generating an upward pulling force, which pulls the limiting block 2 and the control slide 4 upward along the slide groove of the reset slide plate 1101, so that the limiting block 2 returns to the initial position and resumes its limiting function on the locking post 3.

[0024] Reference Figure 4 The adjustment assembly 9 includes a rotating plate 901, which is rotatably connected to the tension strip 8. A control post 902 is fixedly connected to the rear side of the rotating plate 901. Two limit posts 903 are fixedly connected to the inner bottom wall of the tension strip 8, and the control post 902 is located between the two limit posts 903.

[0025] Specifically, the rotating plate 901 is rotatably connected to the tension strip 8. When the first limiting member 1001 and the second limiting member 1002 make non-parallel contact, the rotating plate 901 is allowed to rotate freely within a certain angle range to adjust the angle. When the rotating plate 901 rotates, the control column 902 moves accordingly. The movement trajectory of the control column 902 is limited by the limit column 903, ensuring that the rotation amplitude of the rotating plate 901 is not too large, thus increasing the structural stability.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The electrode pad assembly 12 includes two electrode pad layers 1202, both of which are fixedly connected to the retaining post 3. Electrode pad bodies 1201 are fixedly connected to adjacent sides of the two electrode pad layers 1202. Both electrode pad bodies 1201 are located inside the soft pad layer 14. Both electrode pad layers 1202 are located inside the soft pad layer 14. An electrotherapy device assembly 13 is provided at the bottom of the two electrode pad bodies 1201.

[0027] Specifically, the electrode pad 1202 and the soft pad 14 have the same function: to buffer the pressure between the electrode pad body 1201 and the patient's head, thereby improving the patient's wearing comfort. The electrode pad body 1201 is responsible for transmitting the electrical signals generated by the electrotherapy device component 13 to the patient's scalp to stimulate the corresponding brain region. During the acquisition of electroencephalogram (EEG) signals, it can capture weak electrical signals on the scalp surface and transmit them to subsequent signal processing equipment.

[0028] Reference Figure 3 The first limiting member 1001 is a triangular block, the second limiting member 1002 is a triangular block, the first limiting member 1001 and the second limiting member 1002 have the same shape, and the first limiting member 1001 and the second limiting member 1002 are centrally symmetrical.

[0029] Specifically, the first limiting member 1001 and the second limiting member 1002 are both triangular blocks with the same shape and are centrally symmetrical. This shape design allows the inclined sides of the first limiting member 1001 and the second limiting member 1002 to fit tightly together. When adjusting the position of the tension strip 8 of the head fixing ring 7, the inclined sides of the two are squeezed against each other, generating relative movement.

[0030] Reference Figure 2 Each of the four reset slide plates 1101 has a groove inside, and the size of the groove inside each of the four reset slide plates 1101 is the same as the diameter of the four control slides 4. Each of the four reset components 1102 is a tension spring.

[0031] Specifically, the grooves inside the four reset slide plates 1101 are sized to match the diameter of the four control slides 4. The grooves provide a guide for the control slides 4. When the pressing plate 5 is pressed to move the control slides 4 to remove the electrode, the control slides 4 can slide in the grooves and move along the direction of the grooves to ensure that they do not deviate or shake during the movement. All four reset pieces 1102 are tension springs. Their upper ends are fixed to the bottom of the reset slide plate 1101, and their lower ends are connected to the limit block 2. When the electrode sheet is disassembled, the pressing plate 5 is pressed to make the control slide 4 move the limit block 2, and the tension spring is stretched. At this time, the tension spring stores elastic potential energy. Once the pressing plate 5 is released, the external force is removed, and the tension spring releases its stored elastic potential energy by virtue of its own elastic restoring force, generating an upward pulling force. This pulling force, through its connection with the limiting block 2, pulls the limiting block 2 and the control slide 4 upward along the groove of the reset slide plate 1101, so that the limiting block 2 returns to its initial position and resumes its limiting function on the locking post 3.

[0032] Reference Figure 1 and Figure 4 The electrotherapy device assembly 13 includes an electrotherapy device body 1301, which is electrically connected to two electrode pad bodies 1201. An electrotherapy device control panel 1302 is provided on the top of the electrotherapy device body 1301.

[0033] Specifically, the electrotherapy device body 1301 generates electrical signals with specific frequencies, intensities, and waveforms. Different diseases or treatment purposes require electrical signals with different parameters. The electrotherapy device body 1301 transmits the generated electrical signals to the electrode pad bodies 1201 through electrical connections with the two electrode pad bodies 1201, and then to the patient's head, acting on the corresponding brain regions to achieve therapeutic effects. The electrotherapy device control panel 1302 provides an operating interface for adjusting various parameters of the electrotherapy device.

[0034] Working principle: When it is necessary to remove the electrode sheet, pressure is applied to the pressing plate 5. Since the pressing plate 5 is fixedly connected to the control slide column 4, and the control slide column 4 is fixedly connected to the limiting block 2, the pressure will be transmitted to the control slide column 4 and the limiting block 2, so that the limiting block 2 slides along the slide groove inside the connecting ring 1. The limiting block 2 originally had a limiting effect on the locking column 3 in the control groove 6. After the limiting block 2 slides, it can no longer limit the locking column 3. At this time, the electrode sheet pad 1202 and the electrode sheet body 1201 fixedly connected to the locking column 3 lose their constraint and can be separated from the connecting ring 1, thereby removing the electrode sheet body 1201. When installing the electrode pad, first perform the above-mentioned pressing and pressing plate 5 operation. The reset component 1102 stores elastic potential energy due to being stretched. Align the locking post 3 on the electrode pad pad 1202 with the control groove 6 of the connecting ring 1 and insert it. Release the pressing plate 5. Under the action of the reset component 11, the reset component 1102 releases elastic potential energy to pull the limiting block 2 to reset, so that the limiting block 2 can once again limit the locking post 3, thereby installing the electrode pad body 1201 on the connecting ring 1. This solves the problem that the inconvenience of disassembling and assembling the electrode pad and the head fixation ring 7 affects subsequent treatment operations. When the patient wears the EEG therapy device and needs to adjust the size of the head fixation ring 7, the tension bar 8 is adjusted. The movement of the tension bar 8 drives the control rod 1003, which in turn causes the second limiting member 1002 to move between multiple first limiting members 1001. Since both the first limiting member 1001 and the second limiting member 1002 are triangular blocks and are centrally symmetrically arranged, during the movement, the inclined surface of the first limiting member 1001 will squeeze the inclined surface of the second limiting member 1002, causing the second limiting member 1002 to produce a certain displacement and compress the spring 1005 at the bottom. When adjusted to the appropriate position, the rebound force of the spring 1005 drives the second limiting member 1002 to reset. At this time, the first limiting member 1001 limits the second limiting member 1002, thereby fixing the tension strip 8 and realizing the adaptation of the head fixing ring 7 to different head sizes, thus solving the problem that the head fixing ring 7 cannot adapt to different head sizes.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
