Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 An embodiment of this utility model is provided: a neuromuscular stimulator, including a stimulator body 1, a strap 5 fixedly connected to the left side of the stimulator body 1, a strap 6 fixedly connected to the right side of the stimulator body 1, a positive conductive plate 7 and a negative conductive plate 8 installed at the bottom of the strap 5, a skin impedance detection electrode 9 installed at the bottom of the strap 6, a battery cover 4 slidably connected inside the stimulator body 1, a fixing component is provided inside the battery cover 4, and an adjustment component is provided between the strap 5 and the strap 6.

[0032] The fixing assembly includes a winding rod 19, which is rotatably connected to the inside of the battery cover 4. Two winding ropes 16 are fixedly connected to the outside of the winding rod 19. A spring 15 is sleeved on the outside of the winding ropes 16. A limit plate 13 is fixedly connected to the end of the winding ropes 16 away from the winding rod 19. A plug block 14 is fixedly connected to the outside of the limit plate 13.

[0033] Specifically, the stimulator body 1, as the core component, carries and integrates the main functions and control modules of the instrument; the first strap 5 and the second strap 6 are used to fix the stimulator to a suitable part of the human body, and the tightness of the fit can be flexibly adjusted through the adjustment component between them; the positive conductive plate 7 and the negative conductive plate 8 are installed at the bottom of the first strap 5, responsible for transmitting current to the human body to stimulate nerves and muscles; the skin impedance detection electrode 9 is installed at the bottom of the second strap 6, used to detect skin impedance and provide reference data for current output; the battery cover 4 is used to protect and cover the internal battery; the winding rod 19 drives the winding rope 16 to wind or release by rotation, and the spring 15 is used to provide the reset elasticity, so that the limiting plate 13 and the plug block 14 remain inserted into the stimulator body 1 when there is no external force, ensuring that the battery cover 4 is stable, and when the winding rod 19 is rotated, the plug block 14 can be pulled out, realizing the convenient opening of the battery cover 4.

[0034] Reference Figures 1-3 The adjustment component includes a Velcro female 11 and a Velcro male 10. The bottom of the Velcro female 11 is fixedly connected to the top of the second strap 6, and the top of the Velcro male 10 is fixedly connected to the bottom of the first strap 5. The Velcro male 10 and the Velcro female 11 are bonded together.

[0035] Specifically, the top of the Velcro 10 is fixedly connected to the bottom of the first strap 5, and the bottom of the Velcro 11 is fixedly connected to the top of the second strap 6. The two adhesive properties are used to connect and fix the first strap 5 and the second strap 6, thereby securing the neuromuscular stimulator to the corresponding part of the body. At the same time, the adhesive method of the Velcro 10 and the Velcro 11 allows the user to quickly adjust the wrapping position and tightness of the strap according to their own body shape and treatment area, ensuring that the positive conductive plate 7, the negative conductive plate 8 and the skin impedance detection electrode 9 are in close contact with the skin, ensuring the stability of current conduction and the accuracy of detection, and improving the comfort and applicability of the instrument.

[0036] Reference Figures 1-3 The battery cover 4 has two sliding grooves 12 inside. The outer side of the limiting plate 13 is slidably connected to the inner wall of the sliding groove 12. One end of the spring 15 is fixedly connected to the outer side of the limiting plate 13, and the other end of the spring 15 is fixedly connected to the inner wall of the sliding groove 12. The outer side of the plug block 14 is slidably connected to the inside of the battery cover 4. The top of the winding rod 19 is fixedly connected to the handle 17. The battery cover 4 has a winding groove 18 inside. The outer side of the plug block 14 is inserted into the inside of the stimulator body 1. The stimulator body 1 has two control buttons 1 2 and 2 control buttons 3 inside.

[0037] Specifically, the battery cover 4 is used to protect the battery; the slide 12 provides a sliding track for the limiting plate 13; the limiting plate 13 drives the insertion block 14 to move; the spring 15 provides elastic force to fix the battery cover 4; the insertion block 14 is inserted into the stimulator body 1 to achieve fixation; the winding rod 19 winds or releases the winding rope 16; the handle 17 facilitates the rotation of the winding rod 19; the winding groove 18 stores the winding rope 16; control button 1 2 and control button 2 3 are used to operate the functions of the stimulator body 1.

[0038] Working principle: The first strap 5 and the second strap 6 fix the stimulator body 1 to a suitable part of the body through the adhesion of the Velcro 10 and the Velcro 11, ensuring good contact between the positive conductive plate 7, the negative conductive plate 8 and the skin impedance detection electrode 9 and the skin. The skin impedance detection electrode 9 first detects the skin impedance to provide a reference for the subsequent current output. The first control button 2 and the second control button 3 are used to control the various functions of the stimulator body 1. After starting, the stimulator body 1 outputs current to the human body through the positive conductive plate 7 and the negative conductive plate 8 according to the preset program and the skin impedance detection results, stimulating nerves and muscles to produce contraction.

[0039] When the battery needs to be replaced, turn the handle 17 on the winding rod 19 to drive the winding rod 19 to rotate. The winding rope 16 gradually winds around under the action of the winding rod 19, while compressing the spring 15, causing the limiting plate 13 and the plug block 14 to move towards the winding rod 19 until the plug block 14 is pulled out from inside the stimulator body 1. Then the battery cover 4 can be slid open to replace the battery.
