Description

{Wireless chargeable electroceuticals and electroceuticals set including the same}

The present invention relates to an electronic medicine capable of wireless charging and an electronic medicine set including the same.

Electronic medicine is a compound word of electronics and pharmaceuticals, and refers to an electronic device that treats diseases by controlling electrical signals generated in the brain and nerve cells.

In the early days, simple implantable medical devices such as pacemakers were the mainstay, but recently, they are evolving into electronic devices that stimulate nerve tissue to treat chronic diseases such as epilepsy, diabetes, arthritis, and high blood pressure.

The e-medication is embedded under the skin, and only a specific part that needs treatment is selected and stimulated, so side effects can be minimized, and in case of emergency, the drug effect can be stopped immediately.

However, in the case of currently developed electronic drugs, most of them use primary batteries, so they need to be periodically pulled out of the human body and replaced. There are downsides to having to.

This not only makes management cumbersome, but also involves a problem with a fairly high probability of nerve damage because the process of implanting and withdrawing the electronic drug directly connected to the nerve has to be repeated.

Therefore, it is preferable to use a wireless charging method so that the secondary battery is used but the e-medication itself cannot be withdrawn from the body for a long period of time.
