Embodiment Construction

[0043] figure 1 It is a schematic flowchart of a wireless charging method for an implantable medical device according to an embodiment of the present invention. Wherein, the implantable medical device may be any medical device implanted in the body, such as cardiac pacemaker, brain pacemaker, gastric pacemaker, neuromuscular stimulator, cochlear electronic, etc., and the present invention is not limited thereto. The implantable medical device is provided with a wireless charging receiving module, the wireless charging receiving module includes a receiving coil, and the wireless charging method 100 includes the following steps:

[0044] In step 101, a plurality of transmitting coils in the coil array are sequentially driven;

[0045] In step 102, the average current value of each transmitting coil is detected;

[0046] In step 103, the relative position of the receiving coil is calculated according to the detection result and adjustment information is output, so that the user...

Abstract

The invention relates to a wireless charging method and a wireless charging device for an implantable medical device, wherein the implantable medical device comprises a wireless charge receiving module; the wireless charge receiving module comprises a receiving coil; the method comprises the following steps of: orderly driving a plurality of emitting coils in coil array, inspecting the average current value of each emitting coil; calculating the relative position of the receiving coil according to the results of inspection, and outputting an regulation information so as to conveniently regulate the position of the coil array by the user according to the regulation information, and matching an emitting coil of the plurality of emitting coils with the receiving coil. The wireless charging device comprises a coil array composed of a plurality of emitting coils, a power driving unit, a circuit inspection unit, and a main control unit. The wireless charging method and the wireless chargingdevice for an implantable medical device provided by the invention have the advantages that the position of the receiving coil can be conveniently and quickly determined by orderly driving the plurality of emitting coils in the coil array and inspecting the average current value of each emitting coil, the time for determining the position of the receiving coil is shortened, and the problem of ultra-low charging efficiency caused by inaccurate position of the receiving coil is prevented.

Description

technical field [0001] The present invention relates to the charging technology of implanted medical devices, more specifically, to a wireless charging method and wireless charging equipment for implanted medical devices. Background technique [0002] Today, there are many types of implantable medical devices and a wide range of applications, such as cardiac pacemakers, brain pacemakers, gastric pacemakers, neuromuscular stimulators, cochlear implants, and more. Implantable medical devices are generally expensive and have a short lifespan. In order to prolong the life of implanted medical devices, rechargeable lithium batteries have been used instead of lithium primary batteries to be implanted in patients, and magnetic coupling is used for percutaneous wireless charging. [0003] However, there is only one transmitting coil and one receiving coil in the current charging circuit. The relative position of the two coils has a great influence on the charging efficiency. Sinc...
