Problems solved by technology
After implanting this type of medical device, the user not only needs to learn how to operate the two sets of equipment, but also cannot use the wireless charging function during the program control stage. The operation of the entire system is complicated and the medical cost is relatively high.
[0006] On the other hand, due to the relatively single wireless charging function, traditional medical device manufacturers only use simple methods such as sound or light to prompt the alignment status of the charging device and the implanted medical device. The alignment accuracy is not high, and the charging efficiency cannot reach the best. state, users need to spend more time wirelessly charging implantable medical devices

Embodiment
[0030] The controller generates 4 sets of PWM signals S1, S2, S3, and S4 with adjustable period, duty cycle, and phase through the internal PWM module. The phases and polarities of the four sets of PWM signals are as follows: figure 2 shown. Four groups of PWM signals are respectively connected to the four control ports of the H-bridge drive circuit to control the H-bridge drive circuit to perform periodic commutation.
[0031] The LC resonant circuit is connected in series resonance mode, and the LC resonant circuit is connected with the H bridge drive circuit, and the PWM signal is converted into a sinusoidal electromagnetic wave through periodic commutation logic, and electromagnetic energy is emitted outward. The specific logic is as follows: during T1 period, H1 and H4 are on, H2 and H3 are off, the current direction is H1->C1->L1->H4, output positive electromagnetic waves, during T2 period, H2 and H3 are on, H1 and H4 Disconnect, the current direction is H2->L1->C1->H3...

Description
technical field [0001] The invention relates to an external program-controlled device, in particular to an external program-controlled device with a wireless charging function. Background technique [0002] With the advancement of electrophysiological related technologies, nerve electrical stimulation technology has been more widely used in clinical medicine, especially the clinical use of ultra-high frequency 10KHz stimulation, and the power consumption of nerve electrical stimulation related medical devices has increased significantly. Transdermal wireless charging technology came into being. [0003] Implantable rechargeable medical devices not only require external program-controlled devices to control and exchange data with the devices, but also require wireless power supply devices to charge the devices. [0004] In the classification of medical devices, in vitro program-controlled devices belong to Class II medical devices, while wireless charging devices belong to C...
