Description

Technical Field

[0001] This utility model relates to the field of neuromuscular surgery, and specifically to a neuromuscular electrical stimulation device. Background Technology

[0002] Neuromuscular electrical stimulation technology uses low-frequency pulsed current to stimulate nerves or muscles, causing muscle contraction, and is widely used in fields such as rehabilitation medicine and sports medicine.

[0003] Existing devices often use fixed installations for their electrical stimulation units, which cannot be flexibly adjusted. To change the stimulation site, the entire device must be disassembled or the electrode pads replaced, which is cumbersome and can easily damage components.

[0004] Therefore, it is very necessary to provide a neuromuscular electrical stimulation device to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides a neuromuscular electrical stimulation device to solve the problems of existing electrical stimulation units, which are mostly fixed in installation and cannot be flexibly adjusted in position. Changing the stimulation site requires disassembling the entire device or replacing the electrode pads, which is cumbersome and easily damages components.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A neuromuscular electrical stimulation device includes a seat frame, a restraint member connected to one side of the seat frame for restraining the user's limbs; an electrical stimulation element connected to the other side of the seat frame, the electrical stimulation element including a fixing block connected to the seat frame, two fixing blocks being provided, the two fixing blocks being symmetrically arranged on both sides of the seat frame, a support cylinder being connected between the two fixing blocks, and an electrical stimulation unit being connected to the support cylinder for electrically stimulating the user's neuromuscular system.

[0007] Furthermore, ventilation holes are provided on both sides of the support cylinder.

[0008] Furthermore, the support cylinder is connected to a hook and loop fastener, and the electrical stimulation unit is connected to a hook and loop barb. The electrical stimulation unit is connected to the hook and loop fastener through the hook and loop barb.

[0009] Furthermore, a controller is connected to the frame, and the controller is electrically connected to the electrical stimulation unit. The controller is used to control the opening or closing of the electrical stimulation unit.

[0010] Furthermore, the restraint includes a support block connected to the seat frame, and a restraint strap is connected to the upper side of the support block. The restraint strap and the support block cooperate to fix the user's limbs.

[0011] Furthermore, a U-shaped plate is connected to the lower side of the seat frame, and the U-shaped plate is used to make rotational contact with the support surface.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] By symmetrically placing two fixing blocks on both sides of the seat frame and connecting them with a support cylinder to form a rigid support structure, the electrical stimulation unit maintains spatial stability during use. The electrical stimulation unit is independently connected to the support cylinder, allowing for quick repositioning or adjustment of stimulation modules to suit different patient limb sizes or treatment sites, such as the thigh, calf, or upper limb, enabling precise control of personalized treatment parameters. The seat frame and restraints form a semi-enclosed protective space, effectively isolating the electrical stimulation unit from non-treatment areas and preventing accidental electrode contact by operators or patients. This design solves the problems of existing electrical stimulation units, which are mostly fixed in place and cannot be flexibly adjusted. Changing the stimulation site requires complete disassembly of the device or replacement of the electrode pads, which is cumbersome and prone to damaging components. Attached Figure Description

[0022] like Figures 1 to 3 As shown, a neuromuscular electrical stimulation device includes a seat frame 1. A restraint member 2 is connected to one side of the seat frame 1 for restraining the user's limbs. An electrical stimulation element 3 is connected to the other side of the seat frame 1. The electrical stimulation element 3 includes two fixing blocks 4 connected to the seat frame 1. The two fixing blocks 4 are symmetrically arranged on both sides of the seat frame 1. A support cylinder 5 is connected between the two fixing blocks 4. An electrical stimulation unit 6 is connected to the support cylinder 5 for electrically stimulating the user's neuromuscular system.

[0023] In this embodiment, two fixing blocks 4 are symmetrically arranged on both sides of the seat frame and connected by a support cylinder 5 to form a rigid support structure, ensuring that the electrical stimulation unit 6 maintains a stable spatial position during use. The electrical stimulation unit 6 is independently connected to the support cylinder 5, and its position can be quickly changed or a stimulation module of appropriate specifications can be adapted according to the different limb sizes or treatment sites of different patients, such as the thigh, calf, or upper limb, to achieve precise control of personalized treatment parameters. The seat frame 1 and the restraint member 2 form a semi-enclosed protective space, effectively isolating the electrical stimulation unit 6 from the external non-treatment area and preventing operators or patients from accidentally touching the electrodes.

[0024] In some embodiments, ventilation holes 7 are provided on both sides of the support cylinder 5.

[0025] In some embodiments, the support cylinder 5 is connected to a hook and loop fastener 8, and the electrostimulation unit 6 is connected to a hook and loop barb 9. The electrostimulation unit 6 is connected to the hook and loop fastener 8 through the hook and loop barb 9.

[0026] In some embodiments, a controller 10 is connected to the seat 1, the controller 10 is electrically connected to the electrical stimulation unit 6, and the controller 10 is used to control the opening or closing of the electrical stimulation unit 6.

[0027] In some embodiments, the restraint 2 includes a support block 11 connected to the seat frame 1, and a restraint strap 12 is connected to the upper side of the support block 11. The restraint strap 12 and the support block 11 cooperate to fix the user's limbs.

[0028] In some embodiments, a U-shaped plate 13 is connected to the lower side of the frame 1, and the U-shaped plate 13 is used to make rotational contact with the support surface.

[0029] Example 1:

[0030] The seat frame 1, serving as the basic support structure of the device, is made of high-strength aluminum alloy and has an overall rectangular frame shape. The bottom four corners are connected to U-shaped plates 13 by bolts. The U-shaped plates 13 are made of wear-resistant nylon and are rotatably connected to the seat frame 1 on the inside by bearings. This allows the contact angle between the seat frame and the ground to be adjusted according to the user's sitting posture, while also reducing friction noise during movement.

[0031] The restraint component 2 is used to fix the user's limbs and ensure that the limbs do not move during electrical stimulation. It includes a support block 11 and a restraint strap 12. The support block 11 is a wooden board wrapped with high-density sponge and fixed to one side of the seat frame 1 with screws. The surface is covered with breathable mesh fabric. The restraint strap 12 is a 5cm wide nylon webbing. One end is fixed to one side of the support block 11 with a rivet, and the other end has a plastic male buckle. A female buckle is provided at the corresponding position on the other side of the support block 11. The tightness can be adjusted by the buckles, so that one or two fingers can be inserted.

[0032] The electrical stimulation element 3 includes at least two fixing blocks 4 made of ABS plastic, which are symmetrically welded to the edge of the other side of the seat frame 1 and have screw holes inside for connecting the support cylinder 5.

[0033] The support cylinder 5 is made of lightweight PVC material and is connected to the fixing block 4 at both ends by bolts. It is filled with high-density sponge to increase contact comfort, and the outer surface is covered with breathable mesh fabric. Ventilation holes 7 are evenly distributed on both sides of the support cylinder 5 for heat dissipation and ventilation to prevent localized stuffiness caused by prolonged use.

[0034] The electrical stimulation unit 6 is a rectangular thin sheet structure that integrates electrode pads, a pulse generation module, and a wire interface. A Velcro barb 9 is sewn onto the back of the electrical stimulation unit 6, and a Velcro loop 8 is sewn onto the corresponding position on the surface of the support cylinder 5. The Velcro allows the electrical stimulation unit 6 to be fixed to any position on the support cylinder 5, with an adjustment range covering the entire length of the support cylinder, facilitating stimulation of different muscle groups.

[0035] The controller 10 is installed in a plastic box on the side of the seat frame 1, and has an LCD display and three operation buttons on the front. The controller 10 is connected to the electrical stimulation unit 6 via a flexible wire, which is wrapped with a protective sleeve to prevent bending. It has a built-in rechargeable lithium battery and supports various stimulation modes and intensity adjustment from 0 to 50 mA.

[0036] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0037] By symmetrically placing two fixing blocks on both sides of the seat frame and connecting them with a support cylinder to form a rigid support structure, the electrical stimulation unit maintains spatial stability during use. The electrical stimulation unit is independently connected to the support cylinder, allowing for quick repositioning or adjustment of stimulation modules to suit different patient limb sizes or treatment sites, such as the thigh, calf, or upper limb, enabling precise control of personalized treatment parameters.
