[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figs. 1-2 The illustrated three-dimensional dynamic interference electrotherapy device includes a device body and treatment electrodes. The device body has a lead wire 4. The device body can output three sinusoidal currents with a frequency of 5000Hz flowing in three-dimensional space. The three currents are superimposed and displayed, and are output synchronously through the lead wire 4. After the current vectors are superimposed, the displayed value should not exceed 173mA, with an error of ±10%.

[0026] This utility model's therapeutic electrode includes a fixing strap 1 that can be wrapped around the treatment area. The fixing strap 1 is made of elastic thread. During treatment, the fixing strap 1, which is woven from elastic thread and has a variable length, can reduce the obstruction to the patient's movement, alleviate the feeling of restraint during treatment, and improve the patient's experience.

[0027] Specifically, the fixing band 1 has three U-shaped strips 2, which are evenly arranged around the fixing band 1 and fixed thereon. The open ends of the three U-shaped strips 2 are connected to each other to form a hollow structure 5. The U-shaped strips 2 are made of flexible material and can deform together with the curling of the fixing band 1, which can better fit the physiological curvature of the patient's treatment area and will not cause discomfort to the patient during the treatment process due to the material being too hard.

[0028] The fixing strap 1 of this utility model has three electrode pads 7 installed on the side close to the patient's skin. The three electrode pads 7 are located in the hollow structure 5. One side of the electrode pad 7 is provided with a rectangular connector 8. The width of the rectangular connector 8 is slightly smaller than the width of the U-shaped strip 2. The three electrode pads 7 slide with the three U-shaped strips 2 through the rectangular connector 8. The U-shaped strips 2 can play a certain guiding role for the displacement of the electrode pads 7, ensuring that the placement direction of the electrode pads 7 remains unchanged. This allows the operator to make appropriate adjustments to the placement position of the electrode pads 7 according to the patient's body shape and treatment site without changing the placement direction of the electrode pads 7.

[0029] Specifically, the end of the lead wire 4 furthest from the main body of the treatment device has three sub-wires 3, which are plugged into the rectangular connectors 8 of the electrode pads 7. The three currents output from the main body of the treatment device are transmitted to the three electrode pads 7 through the three sub-wires 3, and the electrode pads 7 come into contact with the patient's skin to generate electrical stimulation to the deep nerves and muscles to achieve the corresponding therapeutic effect.

[0030] The utility model discloses a fixing band 1 is connected by a plurality of hollow grids 6, and the electrode sheet 7 is provided with the fixing buckle that can fix the electrode sheet 7 on the fixing band 1, and the fixing buckle includes two buttons 11 fixed on the diagonal direction of the electrode sheet 7, and the diameter of the button 11 is greater than the diameter of the hollow grid 6.

[0031] Specifically, after adjusting the installation position of the electrode sheet 7 on the fixing band 1, the button 11 is inserted into the mesh hole of the fixing band 1 to realize the fixation of the electrode sheet 7. During treatment, the electrode sheet 7 will not be displaced due to skin sweating, affecting the treatment effect.

[0032] The utility model discloses that one side of the electrode sheet 7 is provided with the conductive adhesive, which can better transmit the current to the treatment part of the patient, and one end of the fixing band 1 is fixedly provided with a plurality of hooks 10, and one end of the fixing band 1 is detachably provided with a hook mounting strip 9, the hook 10 is fixed on the hook mounting strip 9, and the hook 10 can be hooked on the hollow grid 6 of the fixing band 1.

[0033] Specifically, after the fixing band 1 is wrapped around the treatment part of the patient, the hook 10 is hung on the hollow grid 6 of the fixing band 1 to realize fixation, the electrode sheet 7 is wrapped inside the fixing band 1, and the conductive adhesive on the skin contact surface is adhered to the skin of the patient. Under the double action of the fixing band 1 and the conductive adhesive, the situation of falling off due to activity or sweating can be greatly reduced during treatment.

[0034] Specifically, the hollow fixing band 1 also has good air permeability, which can reduce the hot and humid condition of the treatment part and improve the comfort of the patient during treatment in summer.
