Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a charging device and an implantable neural stimulation system. Background Art

[0002] The pulse generator in the implantable neural stimulation system will be implanted in the human body, such as the human head. When used for a long time, the pulse generator needs to be wirelessly charged regularly. Wireless charging mainly uses a charging module containing a charging coil. Wireless charging can be achieved by matching the charging module with the pulse generator and connecting the charging coil to a power source.

[0003] In the prior art, the charging module includes a charger, and a charging coil and corresponding electrical connection circuits are built in the charger. The charging coil is electrically connected to a power source through the electrical connection circuit, so as to charge the pulse generator.

[0004] However, the above-mentioned charging coil is integrated inside the charging part. When charging the pulse generator on the head, the entire charger needs to be fixed on the user's head. When the user needs to interact with the charger to confirm the charging status, the charger needs to be removed and the charging is interrupted before it can be realized. As a result, the charging is interrupted multiple times during the entire charging process, and the charging efficiency is low. Utility Model Content

[0005] The purpose of the utility model is to provide a charging device and an implantable neural stimulation system, which solves the problem in the prior art that the charging coil is integrated in the charger, and the user needs to remove the charger to interrupt charging before interacting with the charger, resulting in multiple interruptions during the charging process and low charging efficiency.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, a charging device is provided for wirelessly charging a pulse generator implanted in a user's head, comprising:

[0008] A fixed sleeve, which is mounted on the user's head;

[0009] A charging unit, which is provided with a charging coil for wireless charging and is arranged on a side of the fixing sleeve close to the user's head and corresponds to the pulse generator;

[0010] A charger, disposed outside the fixing sleeve and electrically connected to the charging unit through a wire; and

[0011] A connecting component is arranged on the outside of the fixing sleeve or hung on the user, and the connecting component is connected to the charger.

[0012] Optionally, a fixed Velcro is provided on the surface of the charger, and the connecting component includes:

[0013] The connecting Velcro is arranged on the outer side of the fixing sleeve and can be bonded with the fixing Velcro.

[0014] Optionally, a buckle is provided on the surface of the charger, and the connecting assembly includes:

[0026] a pulse generator, implanted in the user's head; and

[0027] The charging device described in any one of the first aspects is used to wirelessly charge a pulse generator.

[0028] Beneficial effects of the utility model:

[0029] On the one hand, when the charging device is in use, the charging part and the charger are designed as a split structure. The user keeps the charging part corresponding to the pulse generator, and then powers the charging part through the charger, thereby realizing wireless power supply to the pulse generator. The charger is then fixed to the fixed sleeve or the user's body through the connecting component to avoid pulling on the wire and ensure the stability of the charging process. In this way, the charging device can check the charging status in real time through the split charger, and can ensure that the charging part will not be separated from the pulse generator, so as to ensure that the charging process will not be interrupted, which is conducive to improving the charging efficiency of the pulse generator.

[0030] Secondly, when the implantable neural stimulation system is in use, the pulse generator can be wirelessly charged using a charging device. During the charging process, the user can check the charging status through the charger at any time, and there is no need to separate the charging part from the pulse generator during the checking process, ensuring that the charging process will not be interrupted, effectively improving the charging efficiency of the pulse generator.
