Description

Technical Field

[0001] This utility model relates to a functional electrical stimulator, belonging to the field of functional electrical stimulation technology. Background Technology

[0002] Functional electrical stimulation (FESPS) is an intelligent rehabilitation device that integrates electromyography (EMG) signal detection and muscle stimulation technology. By monitoring the bioelectrical activity of muscles in real time and combining it with a multi-parameter-controlled electrical stimulation system, it can specifically activate target muscle groups. It is widely applicable to the rehabilitation treatment of patients with muscle weakness and motor dysfunction caused by nerve damage, muscle atrophy, sequelae of stroke, spinal cord injury, or post-orthopedic surgery rehabilitation. It can effectively help patients rebuild nerve-muscle connections, improve muscle strength and endurance, and enhance functional motor abilities.

[0003] Existing functional electrical stimulators have the following problems: First, when there are multiple electrical stimulators, it is inconvenient to store and charge them. Second, during electrical stimulation therapy, electrode patches need to be installed on the electrical stimulators via wire harnesses or mechanical connections, and then the electrode patches are attached to the body. The assembly of the electrode patches and the electrical stimulators is cumbersome and inconvenient to store. Third, existing electrical stimulators can only perform electromyographic stimulation and cannot extract muscle contraction information for targeted electrical stimulation, resulting in poor treatment effects.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a functional electrical stimulator that can house multiple pairs of electrical stimulators and charge them simultaneously. Furthermore, it simplifies the assembly of electrode patches and electrical stimulators, and by setting up first and second electrode patches, it accurately collects muscle contraction information, resulting in better therapeutic effects.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A functional electrical stimulator includes a charging storage box, the charging storage box including an upper cover and a base that are hinged to each other by a hinge axis, and a switch notch is provided at the joint where the hinge axes of the upper cover and the base are opposite.

[0008] The base has multiple placement slots arranged in pairs inside, each slot holding an electrical stimulation unit. The electrical stimulation units are arranged in pairs, with each pair including a first electrical stimulation unit and a second electrical stimulation unit, which are connected by a connecting wire.

[0009] A charging electrode head is provided in the placement slot that cooperates with the second electrical stimulation unit. A charging electrode hole is provided at the bottom of the second electrical stimulation unit. When the second electrical stimulation unit is placed in the placement slot, the charging electrode head is inserted into the charging electrode hole to charge the second electrical stimulation unit.

[0010] Furthermore, there are four of each of the first and second electrical stimulation monomers. The placement slot that mates with the second electrical stimulation monomer is located in the middle of the base, and the placement slot that mates with the first electrical stimulation monomer is located near the edge of the base.

[0011] Furthermore, a pressure plate is fixed inside the top cover, and the pressure plate extends inward to form multiple pressure feet, which are arranged one-to-one with the placement slots.

[0012] Furthermore, the second electrical stimulation unit has a winding groove around its periphery, and the connecting wire between the first and second electrical stimulation units is wound inside the winding groove.

[0013] Furthermore, the bottom of the second electrical stimulation unit is provided with two first electrode female buckles, and the first electrical stimulation unit is provided with two first electrode female buckles and one second electrode female buckle.

[0014] Furthermore, a first electrode patch is disposed at the bottom of both the first and second electrical stimulation units. One side of the first electrode patch is provided with two male electrode clips, which are fastened together with the first female electrode clip.

[0015] Furthermore, it also includes a second electrode sticker, which is connected to the electrode connector via a connecting wire. The electrode connector is also provided with a male electrode buckle, which engages with the female electrode buckle of the second electrode.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] The bottom of the second electrical stimulation unit is provided with two first electrode female buckles, the first electrical stimulation unit is provided with two first electrode female buckles and one second electrode female buckle, and one side of the first electrode patch is provided with two electrode male buckles. The electrode male buckles are fastened together with the first electrode female buckles. The second electrode patch is connected to the electrode connector through a connecting wire. The electrode connector is also provided with electrode male buckles. The electrode male buckles on the electrode connector are fastened together with the second electrode female buckles, thereby making the assembly of the electrode patch and the electrical stimulation unit simpler.

[0018] Remove the first and second electrode patches from the electrostimulation unit, wind the connecting wire between the first and second electrostimulation units into the winding groove of the second electrostimulation unit, and place the first and second electrostimulation units into the placement slot for easy storage and charging.

[0019] By analyzing the fluctuation characteristics in electromyography (EMG) signals, the first electrode patch can extract meaningful muscle contraction information, such as key points like the initiation, peak, and termination of muscle activity. Simultaneously, the first electrode patch sends pulsed currents of a specific frequency to the target muscle group to induce functional muscle contraction for treatment. The second electrode patch is used to establish a reference point for EMG signal acquisition. In conjunction with a differential amplifier circuit, it enables interference-resistant acquisition of surface EMG signals and real-time monitoring of muscle contraction status, thereby accurately acquiring muscle contraction information.

[0032] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0033] like Figure 1-5 As shown, this utility model provides a functional electrical stimulator, including a charging storage box. The charging storage box includes an upper cover 1 and a base 2 that are hinged to each other by a hinge shaft 4. A switch notch 3 is provided at the joint where the hinge shafts 4 of the upper cover 1 and the base 2 are opposite each other, so as to facilitate opening the upper cover 1.

[0034] The base 2 has multiple placement slots 8 arranged in pairs inside, and each placement slot 8 holds an electrical stimulation unit. The electrical stimulation units are arranged in pairs, and a pair of electrical stimulation units includes a first electrical stimulation unit 6 and a second electrical stimulation unit 7, which are connected by a connecting line (not shown in the figure).

[0035] A charging head 9 is provided in the placement slot 8 that mates with the second electrical stimulation unit 7. A charging port 10 is provided at the bottom of the second electrical stimulation unit 7. When the second electrical stimulation unit 7 is placed in the placement slot 8, the charging head 9 is inserted into the charging port 10 to charge the second electrical stimulation unit 7. A battery is provided inside the second electrical stimulation unit 7. Since the first electrical stimulation unit 6 and the second electrical stimulation unit 7 are connected by a connecting wire, the battery inside the second electrical stimulation unit 7 supplies power to both the first electrical stimulation unit 6 and the second electrical stimulation unit 7 during treatment.

[0036] Furthermore, the second electrical stimulation unit 7 is equipped with an electromagnet inside, and the placement slot 8 that cooperates with the second electrical stimulation unit 7 is also equipped with an electromagnet. When charging, the second electrical stimulation unit 7 is more firmly attracted to the placement slot 8 by the electromagnet.

[0037] There are four of each of the first electrical stimulation monomer 6 and the second electrical stimulation monomer 7. The placement slot 8 that cooperates with the second electrical stimulation monomer 7 is located in the middle of the base 2, and the placement slot 8 that cooperates with the first electrical stimulation monomer 6 is located near the edge of the base 2.

[0038] like Figure 3 The upper cover 1 also has a pressure plate 5 fixed inside, and the pressure plate 5 extends inward to form a plurality of pressure feet 501, which are arranged one-to-one with the placement groove 8. The pressure feet 501 press the electrostimulation monomer in the placement groove 8 tightly.

[0039] The second electrical stimulation unit 7 has a winding groove 701 around its periphery, and the connecting wire between the first electrical stimulation unit 6 and the second electrical stimulation unit 7 is wound in the winding groove 701.

[0040] like Figure 6 , Figure 7The bottom of the second electrical stimulation unit 7 is provided with two first electrode female buckles 11, and the first electrical stimulation unit 6 is provided with two first electrode female buckles 11 and one second electrode female buckle 12. The top of the first electrical stimulation unit 6 is also provided with a switch button 601.

[0041] like Figure 9 A first electrode patch 13 is disposed at the bottom of both the first electrical stimulation unit 6 and the second electrical stimulation unit 7. One side of the first electrode patch 13 is provided with two male electrode buckles 1301, which are fastened together with the first female electrode buckle 11.

[0042] like Figure 8 The present invention also includes a second electrode sticker 14, which is connected to an electrode connector 15 via a connecting wire. The electrode connector 15 is also provided with an electrode male buckle 1301, which is fastened together with the second electrode female buckle 12.

[0043] During electrical stimulation therapy, one or more pairs of electrical stimulation units are removed from the charging storage box. A first electrode patch 13 is placed at the bottom of both the first electrical stimulation unit 6 and the second electrical stimulation unit 7. The surface of the first electrode patch 13 is coated with conductive gel and then adhered to the human body. By analyzing the fluctuation characteristics in the electromyographic signal, the first electrode patch 13 can extract meaningful muscle contraction information, such as key points like the initiation, peak, and termination of muscle activity. At the same time, the first electrode patch 13 sends pulse currents of a specific frequency to the target muscle group to induce functional muscle contraction for treatment. The second electrode patch 14 is connected to the first electrical stimulation unit 6 through the electrode connector 15. The second electrode patch 14 is used to establish a reference point for electromyographic signal acquisition. With the help of a differential amplifier circuit, it realizes anti-interference acquisition of surface electromyographic signals and real-time monitoring of muscle contraction status, thereby accurately acquiring muscle contraction information.

[0044] After treatment, remove the first electrode patch 13 and the second electrode patch 14 from the electrical stimulation unit, wind the connecting wire between the first electrical stimulation unit 6 and the second electrical stimulation unit 7 into the winding groove 701 of the second electrical stimulation unit 7, and place the first electrical stimulation unit 6 and the second electrical stimulation unit 7 into the placement groove 8 for easy storage and charging.
