Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] See figure 1 , The present invention provides a charging method for an implanted device, which is used for wirelessly charging the implanted device in a body. The methods include:

[0047] Step S100: Obtain the actual temperature and body surface temperature of the implanted device in the body.

[0048] Specifically, the implant device is an implantable medical instrument. The actual temperature within the implanted device is the actual temperature within the implantable medical device within the body. The body surface temperature is a temperature at a certain distance from the skin surf...

Abstract

A charging method of an implantation device is used to perform wireless charging of an implantation device in a body. The method comprises the steps of: S100: obtaining an actual temperature and a body surface temperature in an implantation device in a body; S200: according to a relation of known body surface temperatures and the temperatures in a device and according to the body surface temperature, obtaining a reference temperature range in the device; S300: determining whether the actual temperature is within the reference temperature range or not, if yes, determining temperature feedback data and turning to the S400, if not, turning to the S100; and S400: according to the relation of the temperature feedback data and the temperature expected value in the device, obtaining a current charging regulation parameter, and regulating the charging parameter according to the current charging regulation parameter to perform wireless charging. The method provided by the invention can effectively control the over-heating of the implantation device in the body when the implantation device is charged.

Description

technical field [0001] The invention relates to a wireless charging / power supply system, in particular to a charging method for implanted equipment and a wireless energy transmission device. Background technique [0002] Implantable medical devices are implanted in the patient's body, and are separated from the external charging device by skin and other tissues. Therefore, it is necessary to use a wireless energy transmission system to charge the implanted medical instruments in the body. [0003] The external charging transmitting coil itself generates heat during wireless energy transmission, and transfers the heat to the skin at the charging site through conduction. At the same time, part of the emitted wireless energy itself will be absorbed by human tissue, thereby converting into heat energy. [0004] Implantable medical instruments are generally sealed with biocompatible metal titanium, and implanted batteries are generally installed in implantable medical instrumen...
