Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a neuromuscular electrical stimulation device. Background Art

[0002] Neuromuscular electrical stimulation is a medical method that electrically stimulates nerves and their innervated muscles by outputting low-frequency pulsed current. The electrical stimulation can cause rhythmic contraction of muscles, thereby improving blood circulation, delaying muscle atrophy, and contributing to the compensatory hyperplasia of muscle fibers, having the effect of simulating artificial massage. With the acceleration of people's life rhythm, neuromuscular electrical stimulation devices have gradually become important auxiliary tools in the fields of rehabilitation physiotherapy, sports training, etc.

[0003] In a related art neuromuscular electrical stimulation device, it includes a connecting belt. One surface of the connecting belt is fixedly provided with a pulse generator, and the other surface is provided with stimulating electrodes and patches. During use, the connecting belt is adhered to the skin surface through the patches, the stimulating electrodes are in contact with the skin surface, and the pulse generator transmits stimulating pulses to the stimulating electrodes, and the stimulating electrodes electrically stimulate the neuromuscles under the skin.

[0004] In the process of implementing this application, the applicant found the following problems in this technology: In order to facilitate safe charging, the device needs to be removed from the skin. However, frequently removing the connecting belt will cause the viscosity of the patches to decrease, resulting in insecure adhesion. Content of the Utility Model

[0005] In order to reduce the frequency of removing the connecting belt, try to ensure the viscosity of the patches, and extend the service life of the connecting belt, this application provides a neuromuscular electrical stimulation device.

[0006] A neuromuscular electrical stimulation device provided by this application adopts the following technical solutions:

[0007] A neuromuscular electrical stimulation device includes a connecting belt and a pulse generator. The inner surface of the connecting belt is provided with stimulating electrodes and patches. A battery is arranged in the pulse generator, and a charging port for connecting the battery is provided on the pulse generator. A magnetic sheet group is arranged between the connecting belt and the pulse generator. The magnetic sheet group includes a first magnetic sheet and a second magnetic sheet. The first magnetic sheet is fixedly arranged on the outer surface of the connecting belt, and the first magnetic sheet is electrically connected to the stimulating electrodes. The second magnetic sheet is fixedly arranged on the pulse generator, and the second magnetic sheet is electrically connected to the battery. The first magnetic sheet and the second magnetic sheet have opposite magnetic polarities.

[0008] By adopting the above technical solution, when using the device, the first magnetic sheet and the second magnetic sheet are attracted to each other due to opposite magnetism. The battery transmits the stimulating pulse to the stimulating electrode through the magnetic sheet group, and the stimulating electrode performs electrical stimulation on the neuromuscular under the skin. When charging is required, the first magnetic sheet and the second magnetic sheet are separated from each other, and the battery is disconnected from the stimulating electrode, so that the pulse generator can be temporarily removed from the connecting belt, but the connecting belt still adheres to the skin, reducing the number of times the connecting belt is peeled off, thereby slowing down the reduction of the patch viscosity and ensuring the electrical stimulation effect. In addition, during the reconnection process, the first magnetic sheet and the second magnetic sheet are attracted to each other after approaching magnetically, having an automatic docking effect, which facilitates the connection and disconnection of the pulse generator and the connecting belt.

[0009] Preferably, two groups of magnetic sheet groups are arranged between the connecting belt and the pulse generator. One of the magnetic sheet groups is used to connect the battery and the positive electrode of the stimulating electrode, and the other magnetic sheet group is used to connect the battery and the negative electrode of the stimulating electrode.

[0010] By adopting the above technical solution, using one magnetic sheet group to connect the battery and the positive electrode of the stimulating electrode, and using the other magnetic sheet group to connect the battery and the negative electrode of the stimulating electrode, on the one hand, it improves the stability of the electrical connection between the battery and the stimulating electrode, and on the other hand, it improves the stability of the connection between the connecting belt and the pulse generator.

[0011] Preferably, the first magnetic sheets have opposite magnetism to each other, and the second magnetic sheets have opposite magnetism to each other.

[0012] By adopting the above technical solution, it is restricted that the second magnetic sheet connecting the positive electrode of the battery can only be connected to the first magnetic sheet connecting the positive electrode of the stimulating electrode, and the second magnetic sheet connecting the negative electrode of the battery can only be connected to the first magnetic sheet connecting the negative electrode of the stimulating electrode, thereby preventing the wrong connection of the polarities of the battery and the stimulating electrode.

[0013] Preferably, a convex block is fixedly arranged on the first magnetic sheet, and a groove is pressed on the second magnetic sheet, and the convex block can be inserted into the groove.

[0014] By adopting the above technical solution, when the first magnetic sheet and the second magnetic sheet are attracted to each other, the convex block is inserted into the groove and abuts against the groove, improving the stability when the first magnetic sheet and the second magnetic sheet are connected, preventing dislocation, and ensuring the contact area between the first magnetic sheet and the second magnetic sheet.

[0015] Preferably, two supports are fixedly arranged on the connecting belt, a rotating plate is arranged on the support, one end of the rotating plate is hinged on the support, the other end of the rotating plate is fixedly and vertically provided with a locking buckle, locking grooves are opened on both sides of the pulse generator, the locking grooves are opened on the side of the pulse generator away from the first magnetic sheet, and the locking buckle can be inserted into the locking groove and abut against the locking groove.

[0016] By adopting the above technical solution, the rotating plate is driven to rotate inward, enabling the locking buckle to be inserted into the locking groove and abutted against it, further enhancing the locking effect, improving the connection firmness between the pulse generator and the connecting belt, and preventing the pulse generator from falling off during use.

[0017] Preferably, a third magnetic sheet is provided inside the locking buckle, and fourth magnetic sheets are provided on both sides of the pulse generator, with the third magnetic sheet and the fourth magnetic sheet having opposite magnetic polarities.

[0018] By adopting the above technical solution, when the first magnetic sheet and the second magnetic sheet are docked, it means that the third magnetic sheet approaches the fourth magnetic sheet. At this time, the fourth magnetic sheet attracts the third magnetic sheet to drive the locking buckle to insert into the locking groove and maintain the suction state, enabling the locking buckle to automatically insert into the locking groove and further preventing the pulse generator from falling off during use.

[0019] Preferably, a limiting block is fixedly provided on the support, and an extension block is fixedly provided on the side wall of the rotating plate, and the limiting block can abut against the extension block.

[0020] By adopting the above technical solution, when the rotating plate rotates to the vertical position, the limiting block can abut against the extension block, playing a role in restricting the continuous rotation of the rotating plate, thereby preventing the rotating plate from over-rotating and entering the installation area of the pulse generator, which may hinder the installation of the pulse generator.

[0021] Preferably, a display screen is provided on the pulse generator, and the display screen is electrically connected to the battery. The display screen is used to display the electrical pulse voltage, pulse frequency, and battery power.

[0022] By adopting the above technical solution, the display screen can display the voltage information of the battery in real time, facilitating the user to understand the working state of the battery at any time and perform charging operations as needed. It also records the pulse voltage and pulse frequency of the stimulation device, improving the intuitiveness of the parameters.

[0023] Preferably, a voltage adjustment button and a frequency adjustment button are provided on the pulse generator, and both the voltage adjustment button and the frequency adjustment button are electrically connected to the battery.

[0024] By adopting the above technical solution, the voltage adjustment button and the frequency adjustment button are respectively used to adjust the pulse voltage and pulse frequency output to the stimulation electrode, enabling the user to adjust the parameter settings of the electrical stimulation device according to personal needs and comfort, thereby obtaining a more personalized use experience.

[0026] 1.

[0027] 2. By setting up the support, rotating plate, locking buckle, locking groove, third magnetic sheet, fourth magnetic sheet, and limiting block, the connection firmness between the pulse generator and the connecting band is further enhanced, preventing the pulse generator from falling off during use.

Detailed Description of the Embodiment

[0034] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0035] An embodiment of the present application discloses a neuromuscular electrostimulation device. Refer to Figure 1 and Figure 2, which includes a connecting band 1 and a pulse generator 2. The inner surface of the connecting band 1 is provided with a stimulating electrode 11 and a patch 12. The patch 12 is used to adhere the connecting band 1 to the skin, and the stimulating electrode 11 is used to transmit electrical stimulation to various parts of the skin. A battery is provided inside the pulse generator 2 as the energy source for the stimulating pulse. A charging port 21 electrically connected to the battery is provided on the pulse generator 2 for charging the battery.

[0036] Refer to Figures 1 to 3 , there are two sets of magnetic sheet groups provided between the connecting band 1 and the pulse generator 2. The two sets of magnetic sheet groups are respectively connected to the positive and negative electrodes of the stimulating electrode 11 and the battery. Each set of magnetic sheet groups includes a first magnetic sheet 31 and a second magnetic sheet 32. The first magnetic sheet 31 is fixedly arranged on the outer surface of the connecting band 1 and is electrically connected to the stimulating electrode 11. The second magnetic sheet 32 is fixedly arranged on the pulse generator 2 and is electrically connected to the battery. Importantly, the first magnetic sheet 31 and the second magnetic sheet 32 of each set of magnetic sheet groups have opposite magnetic polarities, the first magnetic sheets 31 of different magnetic sheet groups have opposite magnetic polarities, and the second magnetic sheets 32 also have opposite magnetic polarities, so that the first magnetic sheet 31 of each set of magnetic sheet groups can only attract the corresponding second magnetic sheet 32. Protrusions 311 are fixedly arranged on each first magnetic sheet 31, and correspondingly, grooves 321 are pressed on the second magnetic sheet 32.

[0037] Refer to Figures 1 to 3 , during use, the connecting band 1 is adhered to the skin through the patch 12 to ensure that the stimulating electrode 11 is in close contact with the skin. Subsequently, the pulse generator 2 is brought close to the connecting band 1, so that the first magnetic sheet 31 and the second magnetic sheet 32 are automatically docked due to magnetic attraction. When the first magnetic sheet 31 and the second magnetic sheet 32 are attracted to each other, the protrusion 311 can quickly and accurately insert into the groove 321 and abut against the bottom of the groove 321. The stability when the first magnetic sheet 31 and the second magnetic sheet 32 are connected is improved. The battery transmits the stimulating pulse to the stimulating electrode 11 through the magnetic sheet group, and then electrically stimulates the neuromuscular under the skin. When charging is required, the pulse generator 2 is simply gently removed from the connecting band 1. At this time, the first magnetic sheet 31 and the second magnetic sheet 32 are separated, and the electrical connection between the battery and the stimulating electrode 11 is disconnected. However, the connecting band 1 still adheres to the skin through the patch 12, so there is no need to frequently remove the connecting band 1, thereby effectively slowing down the reduction of the viscosity of the patch 12 and extending the service life of the connecting band 1.

[0038] In order to further enhance the connection firmness between the pulse generator 2 and the connecting band 1, refer to Figure 3 and Figure 4, two additional supports 13 are provided on the connecting belt 1. A rotatable rotating plate 131 is provided on each support 13. One end of the rotating plate 131 is connected to the support 13 through a hinge structure, and a locking buckle 132 is fixedly provided at the other end. The locking buckle 132 is perpendicular to the rotating plate 131 and can rotate inward under the drive of the rotating plate 131. At the same time, locking grooves 22 matching the locking buckle 132 are provided on both sides of the side of the pulse generator 2 away from the second magnetic sheet 32. A third magnetic sheet 133 is fixedly provided on the inner side of the locking buckle 132. At the same time, fourth magnetic sheets 23 are correspondingly provided on both sides of the pulse generator 2.

[0039] Refer to Figure 3 With Figure 4 , when the first magnetic sheet 31 and the second magnetic sheet 32 are docked, the third magnetic sheet 133 and the fourth magnetic sheet 23 are also attracted to each other automatically due to approaching. The third magnetic sheet 133 drives the rotating plate 131 to rotate inward, so that the locking buckle 132 can be inserted into the locking groove 22 and abutted. Thereby further enhancing the connection firmness between the pulse generator 2 and the connecting belt 1, effectively preventing the pulse generator 2 from falling off during use. In addition, a limiting block 134 is fixedly provided on the support 13, and an extension block 135 is fixedly provided on the side wall of the rotating plate 131. The limiting block 134 can abut against the extension block 135. When the rotating plate 131 rotates to the vertical position, the limiting block 134 can abut against the extension block 135, thereby effectively restricting the continuous rotation of the rotating plate 131. As much as possible, the installation of the pulse generator 2 is prevented from being interfered by excessive rotation of the rotating plate 131.

[0040] In order to better meet the needs and usage scenarios of different users, refer to Figure 1 , a display screen 14, a voltage adjustment button 15, and a frequency adjustment button 16 electrically connected to the battery are provided on the side of the pulse generator 2 away from the second magnetic sheet 32. Among them, the display screen 14 reflects information such as battery power, pulse voltage, and pulse frequency. The voltage adjustment button 15 is used to adjust the magnitude of the pulse voltage, and the frequency adjustment button 16 is used to adjust the magnitude of the pulse frequency.

[0041] The implementation principle of a neuromuscular electrical stimulation device according to an embodiment of the present application is as follows: By using the magnetic connection of the magnetic sheet group, the electrical connection between the stimulation electrode 11 and the battery is achieved, and the preliminary connection between the pulse generator 2 and the connecting belt 1 is also achieved. This connection method not only facilitates user operation, but also significantly reduces the number of times the connecting belt 1 is frequently removed, thereby effectively slowing down the reduction rate of the viscosity of the patch 12 and extending the service life of the connecting belt 1. After the first magnetic sheet 31 and the second magnetic sheet 32 attract each other, the third magnetic sheet 133 and the fourth magnetic sheet 23 also automatically attract each other due to approaching each other. The locking buckle 132 is inserted into the locking groove 22 and abuts against it. Further enhancing the connection firmness between the pulse generator 2 and the connecting belt 1, effectively preventing the pulse generator 2 from falling off during use.

[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
