Abstract

The invention discloses a power adjustable wireless charging device applied in an implantable cardiac pacemaker. The power adjustable wireless charging device applied in the implantable cardiac pacemaker comprises a transmitting terminal and a receiving terminal, wherein the transmitting terminal comprises a power adjusting unit, a transmitting coil, a transformer, a control circuit, a drive circuit and a first frequency changer circuit; the power adjusting unit is used for adjusting transmitting power of electromagnetic energy of the transmitting coil; the receiving terminal comprises a receiving coil, a second frequency changer circuit, a rectification filter circuit and a power monitoring circuit; and the power monitoring circuit interacts information with a program controller through a radio frequency identification communication module. The transmitting power of the transmitting coil can be adjusted through the power adjusting unit. According to the power adjustable wireless charging device applied in the implantable cardiac pacemaker, the transmitting power of the transmitting coil can be adjusted through the power adjusting unit, the power consumption and the charging condition of a battery of the cardiac pacemaker can be monitored in real time through the power monitoring circuit, and the power adjustable wireless charging device is applied to wireless charging of the cardiac pacemaker.

Description

[0001] technical field [0002] The invention relates to an electric energy transmission device, in particular to a power-adjustable wireless charging device applied to implantable cardiac pacemakers. Background technique [0003] According to the statistics of the World Health Organization, 17.5 million people die from heart disease every year in the world, and it is estimated that 20 million people will die from this disease in 2015. Bradycardia, arrhythmias, and heart failure can all lead to death. Correct and effective treatment and diagnosis is an important factor for survival, and cardiac pacemaker has become an important technology for the treatment of cardiovascular diseases, and is applied to diseases such as sinus arrest, sinoatrial block, atrial / ventricular ectopic rhythm and tachycardia . [0004] Since the first cardiac pacemaker came out in 1932, human beings have continued to develop and innovate on the basis of cardiac pacing theory and practice. After seve...
