Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an electrode fixing device for an EIT monitoring device. Background Technology

[0002] In the medical field, foot ulcers are a common complication among diabetic patients and other patients with circulatory disorders. If not monitored and treated in time, they may lead to serious infection or even amputation. With the continuous advancement of medical technology, electrical impedance tomography (EIT) technology has shown great potential in the field of medical monitoring due to its non-invasive and real-time monitoring characteristics, especially in the monitoring of skin and subcutaneous tissue lesions. However, because patients' foot shapes and sizes vary significantly, monitoring equipment must have good adaptability and flexibility to ensure that the electrodes can fit closely to the surface of different patients' feet, thereby improving the accuracy and stability of data acquisition. Existing EIT monitoring equipment often has a relatively simple electrode fixation device design, which is difficult to meet the needs of patients with different foot shapes and sizes, resulting in poor monitoring effects, affecting monitoring efficiency, and making it inconvenient to use.

[0003] Therefore, it is necessary to design an electrode fixation device for monitoring foot ulcers by moving electrode contacts, which is easy to adapt to patients with different foot shapes and sizes, facilitates early monitoring and timely treatment, improves the efficiency and effectiveness of monitoring, and is flexible and convenient for use with EIT monitoring equipment. Utility Model Content

[0004] To overcome the shortcomings of existing EIT monitoring devices, which often have relatively simple electrode fixation devices that are difficult to meet the needs of patients with different foot shapes and sizes, resulting in poor monitoring effects, reduced monitoring efficiency, and inconvenience of use, this utility model provides an electrode fixation device for EIT monitoring devices that allows for the monitoring of foot ulcers by moving electrode contacts. This device is easy to adapt to patients with different foot shapes and sizes, facilitates early monitoring and timely treatment, improves monitoring efficiency and effectiveness, and is flexible and convenient to use.

[0005] The technical solution of this utility model is: an electrode fixing device for an EIT monitoring device, including a testing platform, a limiting guard plate, a moving component and a monitoring component. The upper right side of the testing platform is connected to two limiting guard plates, and the right side of the testing platform is provided with a moving component for moving the monitoring component. The moving component is provided with a monitoring component for monitoring the patient's foot.

[0006] As a preferred option, the limiting guard plates are all C-shaped.

[0007] Preferably, the moving component includes a connecting frame, a lead screw, a gear set, a motor, a mounting plate, and limit rods. The connecting frame is connected to the right side of the middle part of the testing table, and the lead screw is rotatably connected to the connecting frame. The motor is connected to the lower right side of the connecting frame, and a gear set is provided between the output shaft of the motor and the lead screw. The mounting plate is threadedly connected to the lead screw, and the mounting plate is slidably connected to the connecting frame. Limit rods are connected to the left side of both the front and rear parts of the mounting plate, and the limit rods are slidably connected to the testing table.

[0008] Preferably, the gear set includes a large gear and a small gear, with the large gear connected to the right side of the lead screw and the small gear connected to the output shaft of the motor, and the small gear meshing with the large gear.

[0009] Preferably, the monitoring component includes electrode plates, electrode posts, electrode contacts, springs, conductive posts, a power supply box, connecting blocks, and a signal interface. Electrode plates are connected to both the front and rear parts of the mounting plate. Multiple electrode posts are attached to each electrode plate via damping sliding clips. Electrode contacts are connected to the left side of each electrode post. Multiple springs are connected to the left side of each mounting plate. Each electrode contact is in contact with an adjacent spring. Multiple connecting blocks are detachably connected to the right side of both the front and rear parts of the mounting plate. A power supply box is connected between four adjacent connecting blocks. Multiple conductive posts are connected to the left side of each power supply box. A signal interface is connected to the side of the power supply box that is furthest from each other.

[0010] Preferably, the connecting blocks are all L-shaped.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The present invention moves the mounting plate so that the electrode contact moves to contact the patient's foot, and then moves the electrode post to contact the conductive post to conduct electricity, so that the electrode contact discharges for monitoring. Thus, the movable electrode contact can monitor the patient's foot ulcers, which is convenient to use for patients with different foot shapes and sizes, facilitates early monitoring and timely treatment, improves the efficiency and effect of monitoring, and is flexible and convenient to use.

[0012] 2. This utility model uses bolts to fix the connecting block, thereby installing the power supply box and conductive post on the mounting plate. Then, the electrode post and electrode plate are snapped together, so that the electrode contact is in contact with the spring. This allows for the installation of the electrode post and electrode contact, facilitating the installation, removal and replacement of the electrode post and electrode contact, reducing maintenance costs and improving ease of use.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] An electrode fixing device for an EIT monitoring device, such as Figures 1-5As shown, the system includes a testing platform 1, limiting guard plates 2, a moving assembly, and a monitoring assembly. The upper right side of the testing platform 1 is connected to two limiting guard plates 2, both C-shaped. A moving assembly for moving the monitoring component is located on the right side of the testing platform 1. The moving assembly includes a connecting frame 3, a lead screw 4, a gear set 5, a motor 6, a mounting plate 7, and limiting rods 8. The connecting frame 3 is connected to the right side of the middle of the testing platform 1. The lead screw 4 is rotatably connected to the connecting frame 3. The motor 6 is connected to the lower right side of the connecting frame 3. The gear set 5, including a large gear and a small gear, is located between the output shaft of the motor 6 and the lead screw 4. The gear set 5 includes a large gear and a small gear. The large gear is connected to the right side of the lead screw 4, and the small gear is connected to the output shaft of the motor 6. The small gear meshes with the large gear. The mounting plate 7 is threadedly connected to the lead screw 4 and slidably connected to the connecting frame 3. Limiting rods 8 are connected to the left sides of both the front and rear sides of the mounting plate 7. The limiting rods 8 are all slidably connected to the detection platform 1. The moving component is equipped with a monitoring component for monitoring the patient's feet. The monitoring component includes an electrode plate 9, electrode posts 10, electrode contacts 11, springs 12, conductive posts 13, a power supply box 14, connecting blocks 15, and a signal interface 16. The electrode plate 9 is connected to both the front and rear parts of the mounting plate 7. Forty-six electrode posts 10 are connected to the electrode plate 9 by damping sliding. The electrode contacts 11 are connected to the left side of each electrode post 10. Forty-six springs 12 are connected to the left side of each mounting plate 7. Each electrode contact 11 is in contact with an adjacent spring 12. Four connecting blocks 15 are detachably connected to the right side of both the front and rear parts of the mounting plate 7. Each connecting block 15 is L-shaped. The power supply box 14 is connected between each of the four adjacent connecting blocks 15. Forty-six conductive posts 13 are connected to the left side of each power supply box 14. The signal interface 16 is connected to the side of the power supply box 14 that is furthest from each other.

[0021] When the EIT monitoring equipment requires electrode fixation, this device can be used to make the connecting block 15 contact the mounting plate 7, and then fix the connecting block 15 with bolts. All connecting blocks 15 are L-shaped. Then, the power supply box 14 and the conductive post 13 are installed on the mounting plate 7. Next, the electrode post 10 is snapped onto the electrode plate 9, so that the electrode contact 11 contacts the spring 12. This allows for the installation of the electrode post 10 and the electrode contact 11, facilitating their installation, removal, and replacement, reducing maintenance costs, and improving ease of use. After installation, the user can lie on the testing table 1. The patient's leg is placed on the limiting guard plate 2, which is C-shaped. Then, the motor 6 is started, driving a small gear to rotate. The small gear meshes with a large gear, causing the lead screw 4 to rotate along the connecting frame 3. Under the action of the thread, the mounting plate 7 moves, causing the limiting rod 8 to move along the detection stage 1. This, in turn, moves the electrode plate 9, the electrode post 10, the electrode contact 11, the conductive post 13, and the power supply box 14, causing the electrode contact 11 to contact the patient's foot. The corresponding electrode contact 11 then moves in the opposite direction, causing the electrode post 10 to move and contact the conductive post 13. The spring 12... When squeezed, the power supply box 14 is energized, and the conductive post 13 conducts electricity, energizing the electrode post 10. This allows the electrode contact 11 to apply a small current to monitor the patient's foot ulcer. The ability to move the electrode contact 11 for monitoring the ulcer makes it suitable for patients with different foot shapes and sizes, facilitating early monitoring and timely treatment, improving monitoring efficiency and effectiveness. It is flexible and convenient to use. During monitoring, the data from an external device is connected via the signal interface 16 to a display device for viewing. After monitoring is complete, the power supply box 14 is de-energized, and the motor 6 reverses its operation, causing the pinion to rotate in the opposite direction. The meshing motion of the gears and the large gear causes the lead screw 4 to rotate in the opposite direction along the connecting frame 3. Under the action of the thread, the mounting plate 7 moves in the opposite direction, causing the limiting rod 8 to move in the opposite direction along the detection stage 1. This, in turn, drives the electrode plate 9, the electrode post 10, the electrode contact 11, the conductive post 13, and the power box 14 to move in the opposite direction, causing the electrode contact 11 to disengage from the patient's foot. The spring 12 rebounds, causing the corresponding electrode contact 11 to move in the opposite direction and reset, causing the electrode post 10 to move in the opposite direction and disengage from the conductive post 13. Then, the motor 6 is turned off, and the patient sits up. After the patient's legs disengage from the limiting guard plate 2, the patient can stand up.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
