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 battery charging of implanted devices is usually achieved by wireless charging to solve the various disadvantages of surgical battery replacement. Especially for the pulse generator implanted in the user's head, the charger and the pulse generator need to be fixed correspondingly to ensure smooth charging.

[0003] In the prior art, the charger is mainly fixed directly on the user's head by means of clamping or sticking. Although the operation is convenient, different users have different physical characteristics, and the clamping or sticking methods are difficult to adapt to different users. Moreover, after the charger is fixed in this way, the charger cannot be adjusted according to the position of the pulse generator, which makes it difficult for the two to completely correspond, resulting in low charging efficiency.

[0004] Therefore, there is an urgent need for a charging device and an implantable neural stimulation system to solve the above problems. 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 that in the prior art, the charger is fixed by clamping or pasting, which is not only difficult to adapt to different users, but also the fixing position cannot be adjusted, and the charger is difficult to correspond to the pulse generator, resulting in low charging efficiency.

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

[0007] In a first aspect, the utility model provides a charging device for charging a pulse generator in vitro, comprising:

[0008] A charger, wherein the charger has connection ears on opposite sides;

[0009] A strap, the strap having a fitting section and two connecting sections, the fitting section is used to fit the jaw and face of the user, and the connecting section is connected to the connecting ears; and

[0010] An adjustment component is arranged on the strap to adjust the distance between the charger and the fitting section and can adjust the position of the charger relative to the user.

[0011] Optionally, the connecting ear is an opening, and a portion of the connecting section passes through the opening and is arranged around the connecting ear.

[0012] Optionally, the connecting ear is a slot, and the binding strap further includes a buckle provided on the connecting section, and the buckle is snap-fitted with the slot.

[0013] Optionally, the adjustment component includes a first adjustment component arranged on the connecting section and a second adjustment component arranged on the fitting section.

[0015] Optionally, the first adjustment component includes a first adjustment buckle arranged on the connecting section, one end of the connecting section is inserted into the first adjustment buckle, and the length of the one end of the connecting section extending beyond the first adjustment buckle is adjustable.

[0016] Optionally, the binding strap comprises two connecting straps arranged opposite to each other, and one end of the connecting strap is fixedly connected to the connecting ear;

[0017] The second adjustment component comprises:

[0018] A second adjusting buckle is provided at the other end of one of the connecting belts and connected to the other connecting belt to adjust the length of the fitting section.

[0019] Optionally, the charging device further includes:

[0020] A fixing sleeve is pressed on the charger and covers the connecting ear.

[0021] Optionally, the fixing sleeve has a plurality of heat dissipation holes.

[0022] In a second aspect, an implantable neural stimulation system comprises:

[0023] a pulse generator, implanted in the user; and

[0024] The charging device as described in any one of the first aspects is used to charge the pulse generator in vitro.

[0025] Beneficial effects of the utility model:

[0026] On the one hand, when the charging device is in use, the charger is first placed on the user's head, and then the strap is placed on the user's chin. The distance between the charger and the fitting section is adjusted by adjusting the assembly so that the strap is tightly tied to the user's head. At this time, the strap can apply tension from the opposite sides of the charger to smoothly fix the charger on the user's head. During the adjustment process, the lengths of the two connecting sections are made different or the lengths of the two sides of the fitting section are made different according to the position of the pulse generator, so that the charger is offset relative to the user and remains corresponding to the pulse generator. In this way, by adjusting the assembly and the strap, the charger can be fixed on the heads of different users, effectively improving the overall adaptability of the charging device. At the same time, the position of the charger relative to the user can be flexibly adjusted according to the position of the pulse generator to ensure that the charger and the pulse generator remain corresponding, so as to effectively improve the charging efficiency of the pulse generator.

[0027] Secondly, when the implantable neural stimulation system is in use, the charging device can be firmly fastened to the user's head through the straps and adjustment components to ensure that the charger and the pulse generator remain in correspondence to maintain a high charging efficiency.

During the adjustment process, the lengths of the two connecting sections 22 are different or the lengths of the two sides of the fitting section 21 are different according to the position of the pulse generator, so that the charger 1 is offset relative to the user and remains corresponding to the pulse generator. In this way, by adjusting the component and the strap 2, the charger 1 can be fixed on the heads of different users, effectively improving the overall adaptability of the charging device. At the same time, the position of the charger 1 relative to the user can be flexibly adjusted according to the position of the pulse generator to ensure that the charger 1 and the pulse generator remain corresponding, so as to effectively improve the charging efficiency of the pulse generator.

[0046] Specifically, the first adjustment component includes at least one Velcro hook surface and at least one Velcro fleece surface provided on the connecting section 22. The Velcro hook surface can be fixed to one end of the connecting section 22 that bypasses the connecting ear 3, and the Velcro fleece surface can be fixed to the outside of the fitting section 21. The Velcro fleece surface is in a long strip shape, and any position of the Velcro fleece surface can be connected to the Velcro hook surface. In other embodiments, the Velcro hook surface can be replaced with a hook, and the Velcro fleece surface can be replaced with a connecting strip with multiple hanging holes.

[0047] By providing the first adjustment component, when the user wears it, the connecting section 22 can be pulled according to the user's physical features, so that the first adjustment component can adjust the length of the corresponding connecting section 22, thereby tightening the strap 2 on the user's head. By adjusting the first adjustment components on both sides respectively, the charger 1 can be offset relative to the user, so that the charger 1 can smoothly correspond to the pulse generator implanted in the user's head.

[0048] Optionally, the charging device further comprises a fixing sleeve (not shown in the figure). The fixing sleeve is pressed on the charger 1 and covers the connecting ear 3 .
