Abstract
The utility model relates to an ultralow frequency magnetic field positioning irradiating instrument applied to biomedical engineering and aims to provide a low frequency magnetic field positioning irradiating instrument capable of real-timely monitoring changes of a magnetic biological effect in terms of biological tissue and even cellular level irradiation. The low frequency magnetic field positioning irradiating instrument comprises a single chip microcomputer module, a signal generation module, a power amplification module, a personal computer (PC) serial port communication module and a magnetic field generating module. By means of the low frequency magnetic field positioning irradiating instrument, the biological tissue and even cellular level can be irradiated, and the magnetic biological effect of the biological tissue and even cellular level can be experimentally monitored; the numerical control of the single chip microcomputer can be achieved, and namely the wave form, frequency, intensity and duty ratio can be adjusted through digital press keys; the frequency, the intensity and the temperature can be digitally displayed, and the wave form can be indicated through indicator lights in different colors; the real-time program control of a PC to the instrument can be achieved, the PC is connected with the instrument through a serial port, and a PC program can adjust the wave form, the frequency, the intensity and the duty ratio and control a switch; the real-time detecting and display of the temperature can be achieved; simultaneously the automatic alarming can be achieved when the temperature exceeds 50 DEG C, and the output can be automatically closed when the temperature exceeds 70 DEG C; and magnetic fields with different accuracies and intensities can be generated through combination of different coils and probes, thereby experiments with different requirements can be performed, real-time update can be achieved, the function update can be performed for an extended port, and the coils and the probes can be constantly updated so as to meet requirements of different experiments.
