In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The utility model discloses a charging device and an implantable neural stimulation system.

[0039] Reference Figures 1 to 3 The charging device is used to wirelessly charge a pulse generator implanted in a user's head, and the charging device includes a fixing sleeve 1, a charging unit 2, and a charger 3. The fixing sleeve 1 is mounted on the user's head; the charging unit 2 has a charging coil for wireless charging inside, and the charging unit 2 is detachably connected to the fixing sleeve 1 through a fixing component.

[0040] Specifically, the fixing sleeve 1 can be a hat, and a fixing component is arranged inside the hat for installing the charging unit 2. The fixing component can be detachably connected with the charging unit 2 at any position of the head. The charging unit 2 can be connected with the fixing sleeve 1 through the fixing component at any position to facilitate the correspondence between the charger 3 and the pulse generator. The charging unit 2 includes a shell and a charging coil arranged inside the shell. The bottom wall of the shell can be in a concave arc shape to form a better fit with the user's head, and the top wall of the shell can be in a convex arc shape to better fit with the fixing sleeve 1.

[0041] By setting the fixing sleeve 1 and the fixing assembly, when the charging part 2 is placed on the user's head and corresponds to the pulse generator, the fixing sleeve 1 can be set on the user's head, so that the charging part 2 is fixed in the fixing sleeve 1 by using the fixing assembly, and the charging coil can wirelessly charge the pulse generator by powering the charging coil. After charging is completed, the user only needs to take off the fixing sleeve 1 to remove the charging part 2 together. In subsequent charging, the user only needs to wear the fixing sleeve 1 to correspond the charging part 2 to the pulse generator. In this way, when the charging device is used, not only can the charging part 2 be fixed on the user's head by using the fixing sleeve 1 and the fixing assembly to reduce the possibility of shaking, but also the charging part 2 can be placed according to the position of the pulse generator. In the user's subsequent charging operation, there is no need to repeatedly position the pulse generator to ensure that the charging part 2 and the pulse generator remain corresponding. That is, when the user charges for the first time, the charging part 2 is positioned with the pulse generator to ensure that the charging part 2 is in the position with the best charging efficiency and charging rate. After positioning, the fixing sleeve 1 is worn, and the charging part 2 is fixed by the fixing assembly to maintain a fixed connection between the fixing sleeve 1 and the charging part 2. The next time you charge, you only need to wear the fixing sleeve 1, and the charging unit 2 can automatically position itself with the pulse generator and be in the best charging position. This effectively simplifies the charging operation, while also improving the charging stability, efficiency and rate. Charging efficiency = (pulse generator receiving voltage * pulse generator receiving current) / (charging coil driving voltage of charging unit 2 * charging coil driving current of charging unit 2) * 100%. The charging rate indicates the amount of charge of the pulse generator per unit time. The faster the charging rate, the shorter the time it takes for the pulse generator to charge to a specified amount of power.

[0042] Optionally, the fixing assembly includes a first fixing portion 4 and a second fixing portion (not shown). The first fixing portion 4 is disposed on the charging portion 2; the second fixing portion is disposed on the inner side of the fixing sleeve 1 and has a plurality of fixing positions that can be detachably connected to the first fixing portion 4.

[0043] Specifically, the first fixing portion 4 can be fixed on the top wall of the charging portion 2, and the fixing method can be bonding, embedding, etc. The second fixing portion can be fixed to the inner side of the fixing sleeve 1 by sewing, and the second fixing portion can cover the entire fixing sleeve 1 to form a plurality of fixing positions on the second fixing portion, and the fixing positions can be bonded or buckled with the first fixing portion 4 in shape.

[0044] By setting the first fixing part 4 on the charging part 2 and the second fixing part on the fixing sleeve 1, when the charging part 2 is placed on the user's head, the user only needs to wear the fixing sleeve 1 so that the first fixing part 4 corresponds to the corresponding fixing position, and the charging part 2 can be fixed to the fixing sleeve 1, thereby quickly completing the fixing of the charging part 2. The setting of multiple fixing positions allows the charging part 2 to be effectively fixed no matter where the charging part 2 is placed on the user's head.

[0045] Optionally, one of the first fixing portion 4 and the second fixing portion is a Velcro fleece surface, and the other is a Velcro hook surface, and a cross-sectional area of ​​the second fixing portion is greater than a cross-sectional area of ​​the first fixing portion 4 .

[0046] Specifically, in this embodiment, the first fixing part 4 is a Velcro hook surface, and the second fixing part is a Velcro fleece surface, then any position of the second fixing part can be used as a fixing position to form a bond with the Velcro hook surface. In other embodiments, the first fixing part 4 is a buckle, and each fixing position has a hidden buckle that can be buckled with the buckle. In order to ensure the stability of the charging part 2 when it is fixed, multiple buckles can be arranged in a ring, and the second fixing part can be a cloth piece at this time. The cloth piece is sewn on the inner side of the fixing sleeve 1, and multiple fixing positions are arranged on the cloth piece. Multiple hidden buckles can be set on each fixing position, so that the charging part 2 can be stably fixed at the fixing position.

[0047] Optionally, the Velcro hook surface has at least one deformation notch 41. Specifically, multiple deformation notches 41 can be provided at intervals on the Velcro hook surface. Since the user's head, the housing of the charging unit 2, and the fixing sleeve 1 all have a certain curvature, it is easy for the Velcro to be arched when it is fixed to the housing of the charging unit. By providing the deformation notch 41, sufficient deformation space can be reserved for the Velcro to avoid the arching. In this embodiment, two deformation notches 41 are distributed at intervals.

[0048] Optionally, the fixing component is made of a breathable and flexible material to facilitate fitting with the head. Specifically, the second fixing part is made of a breathable material, such as cotton cloth, linen cloth, etc. The first fixing part 4 can also be made of a breathable material so that when the charging part 2 is fixed, the heat inside it can be quickly transferred away from the user's head.

[0049] Optionally, the fixing sleeve 1 is provided with a plurality of heat dissipation holes 11. The fixing sleeve 1 is provided with a plurality of through holes as heat dissipation holes 11, and a plurality of heat dissipation holes 11 can be distributed at intervals around the circumference of the fixing sleeve 1 to quickly transfer the heat generated by the charging unit 2 to the external space.

[0050] Optionally, the fixed sleeve 1 has an adjustment belt 12, and the adjustment belt 12 is provided with an adjustment knob 13 for adjusting the tightness of the fixed sleeve 1. Specifically, an adjustment notch 14 is provided on the side of the fixed sleeve 1, and an adjustment belt 12 is provided at the opening of the adjustment notch 14, and an adjustment knob 13 is provided on the adjustment belt 12. The adjustment knob 13 can be rotated to adjust the size of the adjustment notch 14, thereby achieving the effect of adjusting the tightness of the fixed sleeve 1, so that the fixed sleeve 1 can be adapted to the heads of different users. The adjustment belt 12 can be made of elastic material, and the length of the adjustment belt 12 can be changed by rotating the adjustment knob 13. The adjustment belt 12 can also be made of two sections of hard material, and the overlapping length between the two sections can be changed by adjusting the knob 13, and the length of the adjustment belt 12 can also be changed. The specific structure of the adjustment belt 12 and the adjustment knob 13 can be designed according to actual use requirements, and the utility model does not limit this.

[0051] Optionally, the charging device further comprises a strap (not shown in the figure). One end of the strap is connected to one side of the charging part 2, and the other end is passed around the user's lower jaw and connected to the other side of the charging part 2.

[0052] Specifically, the strap can be U-shaped, with its two ends connected to the opposite sides of the charging unit 2 respectively. The strap can be an elastic band, and an adjustment buckle can also be provided to adjust the length of the strap, so that when the user charges for the first time, the strap can be firstly set on the user's lower jaw to fix the charging unit 2 on the user's head, and the position and length of the strap can be adjusted to correspond to the position of the charging unit 2 on the user's head, so that the user can fix the position of the charging unit 2 according to the position of the pulse generator. At this time, the fixing sleeve 1 is set, and the charging unit 2 is fixed by the fixing assembly, then the strap can be removed, and the charging unit 2 can be kept corresponding to the pulse generator by only wearing the fixing sleeve 1. That is, the strap is only used to fix the charging unit 2 when the user charges for the first time. When the fixing sleeve 1 is set on the user's head, it is ensured that the charging unit 2 will not be offset. The charging unit 2 can be fixed on the fixing sleeve 1 by the fixing assembly to determine the best charging position of the charging unit 2. The user only needs to wear the fixing sleeve 1 to fix the charging unit 2 at the best charging position.

[0053] Optionally, the charger 3 is arranged outside the fixing sleeve 1 and is electrically connected to the charging coil of the charging unit 2. Specifically, the charger 3 and the charging unit 2 are arranged as a split structure, that is, the charger 3 is arranged outside the fixing sleeve 1, and it can be installed on the outside of the fixing sleeve 1 by snapping, plugging or bonding, and the charger 3 and the charging unit 2 can be distributed on both sides of the fixing sleeve 1, so that the fixing sleeve 1 can be evenly stressed when worn on the user's head. The charger 3 can also be hung around the user's neck with a lanyard, or can be placed directly in the pocket of the user's clothes, as long as it is ensured that the wire connected to the charging coil will not be pulled.

[0054] The implantable neural stimulation device comprises a pulse generator and a charging device as in the above-mentioned embodiment. The pulse generator is implanted in the user's head; and the charging device is used to charge the pulse generator.

[0055] When the implantable neural stimulation device is in use, the charging device can be used to efficiently and stably charge the pulse generator, thereby effectively ensuring the normal operation of the pulse generator.
