[0046] Embodiment 1

[0047] Reference Figure 1 and Figure 2 The charging device is used to wirelessly charge the pulse generator implanted in the user's head, and includes a charging unit, a charger 1, a prompting component, a charging button 11, and a control button 12. The charging unit is fixed to the user's head; the charger 1 is separately arranged with the charging unit and is electrically connected to the charging unit through a wire; the prompting component is arranged on the charger 1 and can generate a variety of signals for prompting the charging status; the charging button 11 is arranged on the charger 1 and can control the start and stop of the charger 1; the control button 12 is arranged on the charger 1 and is connected to the pulse generator to control the emergency stop of the pulse generator.

[0048] Specifically, a charging coil is provided inside the charging part to wirelessly charge the pulse generator. The charger 1 includes a charging shell, which can be fixed on the outside of the fixed sleeve or hung on the user's body through a lanyard. A power supply and a control circuit board are provided inside the charging shell, the power supply is electrically connected to the charging part through a wire, and the control circuit board is electrically connected to the power supply to obtain the charging status in real time. The prompt component can be provided on the surface of the charging shell and communicated with the control circuit board to convert the charging status into a variety of signals to prompt the user, including voice signals, color light signals, etc. The charging button 11 can be provided in the middle of the charging shell, which is connected to the control circuit board to generate a start or stop signal to the control circuit board, thereby controlling the start and stop of the power supply. The control button 12 can be connected to the pulse generator to remotely control the emergency stop of the pulse generator, so as to facilitate the user to stop the stimulation of the pulse generator in time when feeling uncomfortable.

[0049] The control button 12 is also provided on the surface of the charging case. The control button 12 and the charging button 11 may be located on the same side or on different sides. The charging button 11 and the control button 12 may be coated with different colors to distinguish them, and may also be set at different heights to distinguish them. For example, the charging button 11 protrudes from the surface of the charging case, while the control button 12 may be flush with the surface of the charging case. Other settings may also be used to distinguish the charging button 11 and the control button 12, which may be specifically designed according to the actual size of the charging case.

[0050] When the charging device is in use, the charging part is fixed on the user's head and kept corresponding to the pulse generator. The charger 1 can be started by pressing the charging button 11. Before starting charging, after determining that the charger 1 is not in the program-controlled state, the charger 1 supplies power to the coil inside the charging part to wirelessly charge the pulse generator. During the charging process, the prompt component can generate a variety of signals to prompt the user of the charging status. By setting a control button 12 on the charger 1, the control button 12 can quickly stop the emergency stop of the pulse generator, so that the user can stop the stimulation of the pulse generator in time when uncomfortable. In this way, when the charging device is in use, the user only needs to check the charger 1 to understand the charging status, and there is no need to remove the charging part, ensuring that the charging will not be interrupted, which effectively improves the charging efficiency. Moreover, compared with only generating prompt information through structures such as display screens, the prompt component can generate a variety of prompt information, such as voice signals or light signals, so that users of all ages can clearly understand the charging status in a timely manner, effectively reducing the possibility of interference with the user's use.

[0051] Optionally, the control button 12 and the charging button 11 are respectively arranged on any two surfaces of the charger 1 .

[0052] Specifically, the control button 12 and the charging button 11 are respectively arranged on two opposite sides or two adjacent sides of the charging shell, so that the charging button 11 and the control button 12 are separately arranged, which is convenient for users to distinguish. In this embodiment, the control button 12 and the charging button 11 are respectively arranged on two opposite sides of the charging shell.

[0053] Optionally, the charger 1 has a mounting hole, and the control button 12 is embedded in the mounting hole.

[0054] Specifically, a mounting hole is provided on the side of the charger 1, and the control button 12 is located in the mounting hole, and the surface of the control button 12 can be flush with the surface of the charging shell to avoid accidental contact with the control button 12 during the charging process. When the pulse generator needs to be stopped, the control button 12 can be long pressed, or the control button 12 can be pressed twice in succession. Of course, other modes of operation can also be used to make the control button 12 generate a corresponding control signal. The specific design can be based on actual operation requirements, and this application does not limit this.

[0055] Reference Figure 3Optionally, the prompt component includes a voice prompter, a first indicator light 2, a second indicator light 3, a third indicator light 4 and a fourth indicator light 5. The voice prompter is arranged on the charger 1 and can voice broadcast the charging status. The first indicator light 2 is electrically connected to the control circuit board of the charger 1 to indicate the power of the charger 1 itself; the second indicator light 3 is electrically connected to the control circuit board of the charger 1 to indicate the charging efficiency, and the charging efficiency = (pulse generator receiving voltage × pulse generator receiving current) / (charging coil driving voltage of the program-controlled charger × charging coil driving current of the program-controlled charger) × 100%. The third indicator light 4 is electrically connected to the control circuit board of the charger 1 to indicate whether the charger 1 is in the program-controlled state. The fourth indicator light 5 is electrically connected to the control circuit board of the charger 1 to indicate the power of the pulse generator during the charging process.

[0056] Specifically, a voice hole 13 is provided on the side of the charging shell where the charging button 11 is provided, and a voice prompter is provided on the inner side of the charging shell opposite to the voice hole 13. The control circuit board can convert the charging status into voice and play it through the voice prompter, and the voice is transmitted through the voice hole 13 to prompt the user of the charging status. The first indicator light 2, the second indicator light 3, the third indicator light 4 and the fourth indicator light 5 can all be provided on the side where the voice hole 13 is provided in the charging shell. The four can be distributed at intervals, and the shapes and light colors of the four are different. Specifically, they can be designed in combination with the overall aesthetics of the charger 1. For example, the first indicator light 2 can be red, the second indicator light 3 can be green, the third indicator light 4 can be yellow, and the fourth indicator light 5 can be blue. It should be understood that the above-mentioned indicator light can be provided with only one light-emitting part, or multiple light-emitting parts can be distributed at intervals to indicate the change of state, such as the power consumption. In different embodiments, the first indicator light 2, the second indicator light 3, the third indicator light 4 and the fourth indicator light 5 can be provided with only one of them to display different information by changing different colors, or two or three can be provided, etc., which can be specifically designed according to the actual installation space.

[0057] By setting a voice prompter, a first indicator light 2, a second indicator light 3, a third indicator light 4 and a fourth indicator light 5, the charging situation is converted into a voice signal and a light signal to form a prompt signal, so that the prompt signal has a high degree of recognition, and the charger 1 in this embodiment has a program-controlled state and a charging state, and the state thereof is displayed by the color or on and off of the third indicator light 4. In the program-controlled state, the charger 1 does not charge. When charging is required, the user can stop the program-controlled state of the charger 1, and the charger 1 will automatically enter the charging state for charging. In this way, not only users of all ages can easily identify the charging information, but also the user's operation can be facilitated. That is, when the charger 1 is started, the user can first determine whether the charger 1 is in the program-controlled state by observing the third indicator light 4. If so, the pulse generator needs to be controlled to end the stimulation first. At this time, when the pulse generator senses the charging coil, charging begins. If not, the pulse generator starts charging immediately when it senses the charging coil.

[0058] The implantable neural stimulation system comprises a pulse generator and the above-mentioned charging device. The pulse generator is implanted in the user's body; the charging device is used to wirelessly charge the pulse generator.

[0059] When in use, the implantable neural stimulation system can wirelessly charge the pulse generator using a charging device. During the charging process, the user can confirm the charging status in real time without causing charging interruption. The charging status can be transmitted to the user through a variety of signals, allowing users of different age groups to easily determine the charging status, effectively improving user convenience.

[0060] Embodiment 2

[0061] Based on the first embodiment, the difference between this embodiment and the first embodiment lies in the different arrangement of the control button 12 .

[0062] Reference Figure 4 Optionally, a plurality of control buttons 12 may be distributed at intervals, and the plurality of control buttons 12 may be connected in series to control the emergency stop of the pulse generator when pressed simultaneously.

[0063] Specifically, two control buttons 12 can be spaced apart, and the two control buttons 12 can be arranged in parallel horizontally or vertically to facilitate simultaneous pressing. It should be understood that the number of specific control buttons 12 can be designed according to actual operation requirements, and this application does not limit it. By setting the control buttons 12 to be multiple in series, the possibility of accidental touch during the charging process can be further prevented.

[0064] Embodiment 3

[0065] Based on the first embodiment, the difference between this embodiment and the first embodiment lies in the different arrangement of the control button 12 .

[0066] Reference Figure 5 and Figure 6 Optionally, the charger 1 further comprises a protective cover 6 . The protective cover 6 is movably connected to the side of the charger 1 and covers the control button 12 .

[0067] Specifically, the above-mentioned mounting hole can be opened on the side of the charging case, and the control button 12 is completely embedded in the mounting hole. A protective cover 6 is provided at the opening of the mounting hole. The protective cover 6 can be hinged at the opening of the mounting hole, and the side can partially protrude from the mounting hole. In other embodiments, the protective cover 6 can also be inserted into the mounting hole, or slidably connected to the mounting hole, and it can enclose the control button 12 in the mounting hole, and this application does not limit this.

[0068] By providing a protective cover 6 on the outside of the control button 12, the protective cover 6 is opened when the control button 12 needs to be pressed, and when the control button 12 does not need to be pressed, the protective cover 6 can be installed to close the control button 12, thereby avoiding accidental touching of the control button 12.
