Technical Field

[0001] The utility model relates to the technical field of medical electrodes, in particular to a fixing device for medical electrodes. Background Art

[0002] A medical electrode, also known as an electrode patch, is a medical consumable that achieves a therapeutic effect on a patient by electrically stimulating the local nerves of the patient.

[0003] When the current electrode patch is in use, usually the treatment position is first found, and then the electrode patch with self-adhesive effect is directly adhered to the treatment part of the patient. After use, the doctor needs to remove the electrode patch from the patient; when the same patient uses it again, the doctor needs to find the position again and then paste the electrode patch, resulting in inconvenience for the doctor to determine the treatment position of the patient. Therefore, there is an urgent need to design a fixing device for medical electrodes to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for medical electrodes to solve the above deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixing device for medical electrodes includes a fixing frame. An installation plate is arranged inside the fixing frame. Installation holes are formed inside the installation plate. Two locking plates are movably inserted into the installation holes. A fixing block is integrally formed on the outer wall of the top of the fixing frame. A locking groove is formed inside the fixing block. The locking plates extend into the locking groove. A spring is arranged inside the installation hole and is located between the two locking plates. An activity groove is formed on the outer wall of the top of the installation plate. A connecting block is integrally formed on the outer wall of the top of the locking plate, and the connecting block slides inside the activity groove.

[0007] Furthermore, a cover plate is fixed to the outer wall of the top of the connecting block, and a push block is integrally formed on the outer wall of the top of the cover plate.

[0008] Furthermore, a guide post is fixed to one end of one of the locking plates, and a guide sleeve is fixed to one end of the other locking plate. The guide post is movably inserted into the guide sleeve, and the spring is sleeved outside the guide post and the guide sleeve.

[0009] Furthermore, a wiring component is embedded in the outer wall of the top of the installation plate. An installation cavity is formed on the outer wall of the bottom of the installation plate. A conductive sheet is fixed inside the installation cavity, and the wiring component is electrically connected to the conductive sheet.

[0010] Furthermore, an adhesive layer is arranged on the outer wall of the bottom of the fixing frame, and an isolation layer is adhered to the outer wall of the bottom of the adhesive layer.

[0011] Furthermore, a connecting band is integrally formed on an outer wall of one side of the isolation layer, and uniformly distributed protrusions are arranged on an outer wall of the top of the connecting band.

[0012] In the above technical solution, for a medical electrode fixing device provided by the present utility model, the beneficial effects are as follows: the mounting plate and the fixing frame are fixed through the locking plate and the fixing block, so that after the medical electrode is used, the mounting plate can be disassembled from the inside of the fixing frame, and the fixing frame is left on the patient. Next time when electrode treatment is carried out, only the mounting plate needs to be fixed in the fixing frame, which is convenient for a doctor to determine the position of the electrode on the patient; when the mounting plate is placed inside the fixing frame, the elastic force of the spring can automatically push the locking plate into the locking groove, so that it is more convenient to fix the mounting plate to the fixing frame. The locking plate can be conveniently pushed through the push block, so that it is also more convenient to disassemble the mounting plate from the fixing frame; through the provided bonding layer, the fixing frame can be conveniently bonded and fixed on the patient.

Detailed implementation manners

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0021] As Figures 1-4 shown, a medical electrode fixing device provided by an embodiment of the present utility model includes a fixed frame 1. An mounting plate 2 is arranged inside the fixed frame 1. Mounting holes 4 are formed inside the mounting plate 2. Two locking plates 5 are movably inserted into the mounting holes 4. A fixing block 6 is integrally formed on the outer wall of the top of the fixed frame 1. A locking groove 7 is formed inside the fixing block 6. The locking plates 5 extend into the locking groove 7. A spring 8 is arranged inside the mounting hole 4. The spring 8 is located between the two locking plates 5. A moving groove 9 is formed on the outer wall of the top of the mounting plate 2. A connecting block 12 is integrally formed on the outer wall of the top of the locking plate 5. The connecting block 12 slides inside the moving groove 9.

[0022] Specifically, in this embodiment, it includes a fixed frame 1. An mounting plate 2 is arranged inside the fixed frame 1. Mounting holes 4 are formed inside the mounting plate 2. Two locking plates 5 are movably inserted into the mounting holes 4. A fixing block 6 is integrally formed on the outer wall of the top of the fixed frame 1. A locking groove 7 is formed inside the fixing block 6. The locking plates 5 extend into the locking groove 7, so that the fixed frame 1 and the mounting plate 2 can be fixed. A spring 8 is arranged inside the mounting hole 4. The spring 8 is located between the two locking plates 5. The spring applies an elastic force to the locking plates 5. A moving groove 9 is formed on the outer wall of the top of the mounting plate 2. A connecting block 12 is integrally formed on the outer wall of the top of the locking plate 5. The connecting block 12 slides inside the moving groove 9, so that the connecting block 12 can drive the locking plates 5 to move when it moves.

[0023] A medical electrode fixing device provided by the present utility model fixes the mounting plate 2 and the fixed frame 1 through the locking plates 5 and the fixing block 6. Furthermore, after the medical electrode is used, the mounting plate 2 can be disassembled from the inside of the fixed frame 1, and the fixed frame 1 is left on the patient. Next time when electrode treatment is carried out, only the mounting plate 2 needs to be fixed inside the fixed frame 1, which is convenient for doctors to determine the position of the electrode on the patient. At the same time, the central part of the fixed frame 1 is a hollow structure, and the air permeability is better than that when the whole electrode sheet is left on the patient.

[0024] In another embodiment provided by the present utility model, a cover plate 10 is fixed to the top outer wall of the connecting block 12. The cover plate 10 covers the movable slot 9. A push block 11 is integrally formed on the top outer wall of the cover plate 10. When the push block 11 is pushed, the locking plate 5 can be driven to move. One end of one of the locking plates 5 is fixed with a guide post 13, and one end of the other locking plate 5 is fixed with a guide sleeve 14. The guide post 13 is movably inserted into the inside of the guide sleeve 14. With the cooperation of the guide post 13 and the guide sleeve 14, the movement of the locking plate 5 is more stable. The spring 8 is sleeved outside the guide post 13 and the guide sleeve 14, making the compression of the spring 8 more stable. A wiring component 3 is embedded in the top outer wall of the mounting plate 2. The wiring component 3 is a connector for wire connection with the therapeutic instrument, enabling the electrode patch to be electrically connected to the therapeutic instrument. An installation cavity 15 is opened on the bottom outer wall of the mounting plate 2, and a conductive sheet 16 is fixed inside the installation cavity 15. The wiring component 3 is electrically connected to the conductive sheet 16. The conductive sheet 16 is made of conductive silicone material, enabling the conductive sheet 16 to be in full contact with the skin. A bonding layer 18 is provided on the bottom outer wall of the fixed frame 1. Through the bonding layer 18, the fixed frame 1 is bonded and fixed to the patient. The position where the fixed frame 1 is fixed is a relatively flat position on the patient's skin. A separation layer 19 is bonded to the bottom outer wall of the bonding layer 18. The separation layer 19 is a plastic film. Through the provided bonding layer 18, the fixed frame 1 can be conveniently bonded and fixed to the patient. Through the separation layer 19, it can be prevented that the bonding layer 18 is contaminated with dust before use. A connecting belt 17 is integrally formed on one side outer wall of the separation layer 19. Uniformly distributed protrusions 20 are provided on the top outer wall of the connecting belt 17. Through the protrusions 20 on the connecting belt 17, the friction between the hand and the connecting belt 17 can be increased, making it more convenient to remove the separation layer 19.

[0025] Working principle: Pull the connecting belt 17 to remove the separation layer 19 from the bottom of the bonding layer 18. Then bond the fixed frame 1 to the part of the patient that needs electrode stimulation. Then put the mounting plate 2 into the inside of the fixed frame 1, so that the locking plate 5 cooperates with the locking groove 7 of the fixed block 6, thereby fixing the mounting plate 2 and the fixed frame 1. Then connect the wiring component 3 and the therapeutic instrument through a wire. When the electrode treatment of the patient is completed, move the two push blocks 11 closer to each other, so that the push blocks 11 drive the locking plate 5 to separate from the locking groove 7 of the fixed block 6. Then take out the mounting plate 2 from the inside of the fixed frame 1 and leave the fixed frame 1 at the treatment part of the patient. When performing treatment next time, directly fix the mounting plate 2 and the fixed frame 1, without the need for secondary bonding of the fixed frame 1, and making it more convenient for the doctor to determine the electrode treatment position.

[0026] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
