Implanted medical equipment charging device

Abstract

The invention discloses a charging device for implanted medical equipment. The charging device comprises an in vitro part and an in vivo part, wherein the in vitro part comprises a DC power supply, a DC motor speed controller, a DC motor and an externally-arranged magnet, the in vivo part a voltage-stabilizing diode, a filtering capacitor, a rectifying bridge, a generator and an internally-arranged magnet, the DC power supply supplies power to the DC motor through the DC motor speed controller, the externally-arranged magnet is fixedly arranged on an output shaft of the DC motor, the internally-arranged magnet is fixedly arranged on a rotating shaft of the generator, two AC output ends of the generator are connected with two AC input ends of the rectifying bridge, two DC output ends of the rectifying bridge are connected with two ends of the filtering capacitor, the voltage-stabilizing diode and the filtering capacitor are parallelly arranged, a negative electrode of the voltage-stabilizing diode is connected with a positive electrode of a battery of medical equipment inside the body of a patient, and a positive electrode of the voltage-stabilizing diode is connected with a negative electrode of the medical equipment. The charging device can be used for charging the implanted medical equipment inside the body of the patient conveniently, can effectively avoid influence of external electromagnetic interference during the charging process, has good charging effect, and is high in charging efficiency.

Description

technical field [0001] The invention relates to a charging device for implanted medical equipment. Background technique [0002] There are many types of implantable medical devices, and their applications are also wide, such as cochlear implants, cardiac pacemakers, deep brain stimulators, artificial sphincters, peripheral nerve stimulators, and muscle stimulators. [0003] The service life of various implantable medical devices mainly depends on the power of the battery. In such devices, when the power of the battery is low, the operation of charging the battery is extremely troublesome, and sometimes even requires surgery to replace the battery. Existing A method of charging the battery in the patient's body through coil electromagnetic coupling. Although the patient does not need to be operated on, the charging effect is not ideal. This method is very susceptible to external electromagnetic interference during the charging process, which will not only seriously Reduce ch...

[0003] The service life of various implantable medical devices mainly depends on the power of the battery. In such devices, when the power of the battery is low, the operation of charging the battery is extremely troublesome, and sometimes even requires surgery to replace the battery. Existing A method of charging the battery in the patient's body through coil electromagnetic coupling. Although the patient does not need to be operated on, the charging effect is not ideal. This method is very susceptible to external electromagnetic interference during the charging process, which will not only seriously Reduce charging efficiency and affect the normal service life of the battery
