Abstract

The invention discloses a magnetic coupling resonance wireless charging device of an implanted cardiac pacemaker. The device comprises a high-frequency excitation source (10), an emission unit (20), a receiving unit (30), an energy conversion unit (40) and a rechargeable battery; by means of magnetic coupling resonance of a resonance circuit of the emission unit (20) and a resonance circuit of the receiving circuit (30), wireless transmission of electric energy from the emission side to the receiving side is achieved. The energy conversion unit (40) conducts smoothing on the electric energy of the receiving unit (30), and the electric energy required by charging of the rechargeable battery of the cardiac pacemaker is obtained through a battery management chip. The high-frequency excitation source (10) and the emission unit (20) belong to outside components, and the receiving unit (30) and the energy conversion unit (40) belong to inside components. The device charges the rechargeable battery of the implanted cardiac pacemaker in a wireless mode, and therefore service life of the battery is prolonged, and service life of the implanted cardiac pacemaker is prolonged.

Description

technical field [0001] The invention relates to a charging device for a rechargeable battery of an implantable cardiac pacemaker, more particularly, to a magnetic coupling resonance wireless charging device for an implantable cardiac pacemaker. Background technique [0002] When the self-discipline of the patient's heart excitation is destroyed or the function of myocardial cells is impaired, it will lead to blood supply dysfunction and even life-threatening; at this time, the patient needs to be installed with a cardiac pacemaker. The cardiac pacemaker uses a pulse current of a certain size to stimulate the heart, so that the heart contracts and relaxes at a certain frequency to achieve the purpose of cardiac pacing. The existing cardiac pacemaker includes a pulse generator, a stimulating electrode in contact with the heart tissue and a battery, and the pulse generator, the stimulation electrode in contact with the heart tissue and the battery are sequentially connected thr...
