Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electrode patch assembly that is easy to install. Background Technology

[0002] In the field of neurology, electroencephalography (EEG) monitoring is an important non-invasive examination technique widely used in the diagnosis and monitoring of neurological diseases. Its core principle is based on electrophysiology, that is, when brain neurons are active, they generate weak electrical signals. These signals can be captured and recorded by specific devices. Electrode patches are used in the EEG monitoring process.

[0003] Currently, most electrode patch designs on the market use point-like or strip-like conductive elements that are directly soldered to wires or connected via plug-in connectors. Although these designs achieve signal transmission between the electrodes and the EEG machine to a certain extent, with long-term use, due to factors such as scalp oil, sweat, unconscious scratching by the patient, or daily activities, these connection points are prone to physical wear or chemical corrosion, leading to poor contact or complete disconnection. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing electrode patch wire design often lacks sufficient flexibility and fixing mechanism. Therefore, we propose an electrode patch assembly that is easy to install.

[0005] To achieve the above objectives, this application adopts the following technical solution: an electrode patch assembly that is easy to install, comprising an electrode patch body, a power cord installed at the front end of the electrode patch body, a connecting post installed at the front end of the power cord, a rotating post rotatably connected inside the connecting post, a connecting wire provided inside the rotating post, adjustment grooves provided at both ends of the rotating post, arc blocks fixedly connected at both ends of the inner wall of the connecting post, a push block slidably connected inside the adjustment groove, a plug rod fixedly connected to the side of the push block away from the arc block, and insertion holes provided at both ends of the connecting wire.

[0006] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0007] Preferably, both ends of the adjustment groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0008] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0009] Preferably, a rubber pad is installed inside the connecting post on the side near the connecting line.

[0010] Preferably, screw holes are provided on both sides of the rotating column, and screws are installed on both sides of the connecting column.

[0011] Preferably, the inner wall of the connecting column is provided with two annular grooves, and two annular blocks are fixedly connected to the surface of the rotating column.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator rotates the rotating column inside the connecting column, inserting the connecting wire into the rotating column. During the rotation of the rotating column, the arc block gradually squeezes the push block, causing the push block to drive the insertion rod into the insertion hole to limit the position of the connecting wire. Through the above settings, the operator can stabilize the line, prevent it from falling off, facilitate installation, and improve stability. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: an electrode patch assembly that is easy to install, including an electrode patch body 1, a power cord 2 installed at the front end of the electrode patch body 1, a connecting post 3 installed at the front end of the power cord 2, a rotating post 4 rotatably connected inside the connecting post 3, a connecting wire 5 disposed inside the rotating post 4, adjustment grooves 6 opened at both ends of the rotating post 4, arc blocks 7 fixedly connected at both ends of the inner wall of the connecting post 3, a push block 8 slidably connected inside the adjustment groove 6, a plug rod 10 fixedly connected to the side of the push block 8 away from the arc block 7, and plug holes 11 opened at both ends of the connecting wire 5. The operator operates the rotating post 4 to rotate inside the connecting post 3, and inserts the connecting wire 5 into the inside of the rotating post 4. During the rotation of the rotating post 4, the arc block 7 gradually squeezes the push block 8, so that the push block 8 drives the plug rod 10 to insert into the plug hole 11 to limit the position of the connecting wire 5. Through the above settings, the operator can stabilize the wire, facilitate installation, and avoid detachment.

[0022] Reference Figure 3 and Figure 4 As shown in this embodiment: the size of the insertion rod 10 is adapted to the size of the insertion hole 11, and the surface of the insertion rod 10 is inserted into the interior of the insertion hole 11. By adapting the size of the insertion rod 10 to the size of the insertion hole 11, the insertion rod 10 can be stably inserted into the interior of the insertion hole 11, thereby achieving a stable connection between the rotating post 4 and the connecting line 5. This effectively prevents the rotating post 4 from shaking or falling off when rotating inside the connecting post 3, and improves the stability and reliability of the overall structure.

[0023] Reference Figure 3 As shown in this embodiment: both ends of the adjusting groove 6 are provided with sliding grooves 12, and both ends of the push block 8 are fixedly connected with sliders 13. The surface of the sliders 13 is slidably connected to the inside of the sliding grooves 12. When the operator moves the push block 8, the push block 8 drives the sliders 13 to slide inside the sliding grooves 12. Through the above settings, the movement of the push block 8 is more stable, avoiding the push block 8 from shaking or deviating during the movement, thereby improving the stability and reliability of the overall structure. At the same time, the sliding connection design between the sliders 13 and the sliding grooves 12 also makes the movement of the push block 8 smoother, reduces the frictional resistance during the movement, and further improves the efficiency of use.

[0024] Reference Figure 3As shown in this embodiment: a storage spring 9 is fixedly connected to the side of the push block 8 near the insertion rod 10, and the side of the storage spring 9 away from the push block 8 is fixedly connected to the inside of the adjustment groove 6. During the rotation of the rotating column 4, the arc block 7 gradually squeezes the push block 8, causing the push block 8 to squeeze the storage spring 9 to compress and store force, while driving the insertion rod 10 to be inserted into the insertion hole 11 for fixation. When the operator releases the contact between the push block 8 and the arc block 7, the push block 8 is quickly ejected under the action of the rebound force of the storage spring 9, and the insertion rod 10 is released from the limit between itself and the insertion hole 11.

[0025] Reference Figure 3 As shown in this embodiment: a rubber pad 14 is installed inside the connecting post 3 on the side near the connecting line 5. By installing the rubber pad 14 inside the connecting post 3 on the side near the connecting line 5, the connecting line 5 can be effectively protected, avoiding wear and tear on the connecting line 5 during contact with the connecting post 3, thereby extending the service life of the connecting line 5. At the same time, the rubber pad 14 also has a certain elasticity, which can buffer the vibration generated by the connecting line 5, further improving the stability and reliability of the connection.

[0026] Reference Figure 3 and Figure 5 As shown in this embodiment: screw holes 15 are provided on both sides of the rotating column 4, and screw rods 16 are installed on both sides of the connecting column 3. With the setting of screw holes 15 and screw rods 16, after the operator limits the position of the connecting line 5, the operator inserts the screw rods 16 into the screw holes 15 for limiting, so as to prevent the rotating column 4 from rotating inside the connecting column 3.

[0027] Reference Figure 3 and Figure 5 As shown in this embodiment: the inner wall of the connecting column 3 is provided with two annular grooves 17, and two annular blocks 18 are fixedly connected to the surface of the rotating column 4. When the operator rotates the rotating column 4, the rotating column 4 drives the annular grooves 17 to rotate inside the annular blocks 18. Through the above arrangement, the rotation of the rotating column 4 is more stable, avoiding shaking or deviation during the rotation process, improving the overall use effect and stability. At the same time, the cooperation between the annular grooves 17 and the annular blocks 18 also plays a limiting role, effectively controlling the rotation range of the rotating column 4, and further ensuring the safety of use.

[0028] Working principle: The operator rotates the rotating post 4 inside the connecting post 3, inserting the connecting wire 5 into the rotating post 4. During the rotation of the rotating post 4, the arc block 7 gradually presses against the push block 8, causing the push block 8 to drive the insertion rod 10 into the socket 11, limiting the position of the connecting wire 5. This setting allows the operator to secure the wire and prevent it from falling out. The size of the insertion rod 10 is matched with the size of the socket 11, allowing the insertion rod 10 to be stably inserted into the socket 11, thus achieving a stable connection between the rotating post 4 and the connecting wire 5. This effectively prevents the rotating post 4 from shaking or falling out during rotation inside the connecting post 3, improving efficiency. To ensure the stability and reliability of the overall structure, when the push block 8 is moved, it drives the slider 13 to slide inside the groove 12. This design makes the movement of the push block 8 more stable, preventing it from shaking or shifting during movement, thus improving the overall stability and reliability of the structure. Simultaneously, the sliding connection design between the slider 13 and the groove 12 makes the movement of the push block 8 smoother, reducing frictional resistance and further improving efficiency. During the rotation of the rotating column 4, the arc block 7 gradually presses against the push block 8, causing it to compress and store force on the energy storage spring 9, simultaneously driving the insertion rod 1. The plug is inserted into the socket 11 for fixation. When the operator releases the contact between the push block 8 and the arc block 7, the push block 8 is quickly ejected by the rebound force of the storage spring 9, which in turn causes the plug rod 10 to release its limit between itself and the socket 11. The rubber pad 14 installed inside the connecting post 3 near the connecting wire 5 effectively protects the connecting wire 5, preventing wear during contact with the connecting post 3 and extending its service life. Simultaneously, the rubber pad 14 has a certain degree of elasticity, which buffers the vibration generated by the connecting wire 5, further improving the stability and reliability of the connection. With the screw hole 15 and screw 16 in place, after the operator limits the position of the connecting line 5, the operator inserts the screw 16 into the screw hole 15 for further limiting, preventing the rotating column 4 from rotating inside the connecting column 3. When the operator rotates the rotating column 4, the rotating column 4 drives the annular groove 17 to rotate inside the annular block 18. Through the above settings, the rotation of the rotating column 4 is more stable, avoiding shaking or deviation during rotation, improving the overall performance and stability. At the same time, the cooperation between the annular groove 17 and the annular block 18 also plays a limiting role, effectively controlling the rotation range of the rotating column 4, further ensuring the safety of use.
