Description

Technical Field

[0001] The present invention relates to the field of circuit control technology, in particular to magnetic stimulation frequency and intensity conversion technology. Background Art

[0002] In the field of pelvic floor magnetism, the pelvic floor muscles of different human bodies have different tolerance levels to stimulations of different frequencies and intensities, so when formulating a plan, it is necessary to adjust the frequency range of stimulation according to the specific conditions of the tolerance level. Moreover, if a fixed frequency of stimulation is used for a long time, the pelvic floor muscles may experience adaptive fatigue. Frequency conversion technology avoids the adaptive fatigue of muscles to a certain frequency by constantly changing the frequency and intensity, allowing the muscles to maintain a high level of responsiveness. However, existing frequency conversion technology generally acts on different pulse sequences, that is, each change in frequency is sandwiched with a rest period, and the intensity of each pulse sequence cannot be changed. This results in sudden changes in frequency and intensity throughout the magnetic stimulation process, and the stimulation of the muscles is not continuous, and the expected magnetic stimulation results for the pelvic floor muscles cannot be obtained.

[0003] Therefore, a new technical solution is needed to solve the above problems. Summary of the invention

[0004] Purpose of the invention: The present invention provides a variable frequency and variable intensity device for pelvic floor magnetic stimulation, which is capable of continuously outputting magnetic stimulations of different frequencies and intensities in the same pulse sequence, thereby solving the problem that the intensity of each pulse sequence generated by the pelvic floor magnetic stimulation device in the prior art cannot be changed.

[0005] Based on the same purpose, the present invention also provides a control method for the variable frequency and variable intensity device.

After reaching the set frequency value, the power supply is turned off to charge the pulse capacitor.

[0015] Furthermore, the magnetic beat is used to generate a magnetic field after the capacitor is discharged.

Among them:

[0036] The power supply is connected to the pulse capacitor through a wave-avoiding circuit, and the pulse capacitor is connected to the magnetic beat through a thyristor.

[0037] The lower computer control system is used to control: the power supply charging the pulse capacitor, the on and off of the wave avoidance circuit, and the on and off of the thyristor. The lower computer control system includes a single-chip microcomputer. The frequency of the pulse sequence sent by the upper computer is converted by the single-chip microcomputer into the minimum working cycle of the timer in the single-chip microcomputer (for example, the timer cycle is 20us, if the stimulation frequency is 1Hz, it corresponds to 50,000 timer cycles), and the timer is enabled and starts charging the pulse capacitor. After reaching the set frequency value, the power supply is turned off to charge the pulse capacitor.

[0038] The ripple avoidance circuit connects the power supply and the pulse capacitor when the power supply charges the pulse capacitor, and disconnects the ripple avoidance circuit when the pulse capacitor discharges.

[0039] The thyristor connects the pulse capacitor and the magnetic beat when the pulse capacitor is discharged, and the thyristor is disconnected when the pulse capacitor is charged.

[0040] The upper computer is used to send the frequencies in the pulse sequence and the corresponding stimulation intensity at each frequency to the lower computer control system.

[0041] The cooling system is used to dissipate heat for the magnetic beater, pulse capacitor and power supply.

[0042] Magnetic beats are used to generate a magnetic field after the capacitor is discharged.

[0043] The control method of the variable frequency and variable intensity device for pelvic floor magnetic stimulation comprises the following steps:

[0044] (1) The host computer presets the number of single pulses in a pulse sequence, the frequency of each single pulse, and the corresponding stimulation intensity at each frequency. Set multiple pulse sequences, and set an interval time between two adjacent pulse sequences. Among them, the frequency of each single pulse can be set to a maximum of ten frequencies and the intensity corresponding to each frequency. The maximum frequency is 150Hz (considering that the fastest charging time of the capacitor is 5ms, the maximum frequency is set at 150Hz), and the maximum voltage is 1900V. By setting the frequency and intensity parameters, the charging and discharging of the capacitor is controlled and the charging voltage of the high-voltage power supply is set to achieve variable frequency and variable intensity output. The waveform of the single output and the waveform of the variable frequency and variable intensity output are as follows. Figure 4 As shown, multiple pulse sequences with variable frequency and intensity are as follows Figure 3 shown.

[0045] (2) The power supply is made to charge the pulse capacitor, and the intensity of the stimulation output of the first pulse is controlled by controlling the charging voltage of the power supply within the frequency of the first pulse.

[0046] (3) Turn off the power supply in sequence to charge the pulse capacitor, disconnect the wave avoidance circuit, turn on the thyristor to discharge the pulse capacitor to the magnetic beat to complete a pulse output, and increase the single pulse count by 1.

[0047] (4) Determine whether the total number of single pulses reaches a preset value. If so, the process ends; if not, the process proceeds to the next step.

[0048] (5) The power supply is again charged to the pulse capacitor, and the intensity of the next output stimulation is controlled by controlling the charging voltage of the power supply within the frequency of the next pulse.

[0049] (6) Turn off the power supply in sequence to charge the pulse capacitor, disconnect the wave avoidance circuit, turn on the thyristor to discharge the pulse capacitor to the magnetic beat to complete a pulse output, and increase the single pulse count by 1.

[0050] (7) Determine whether the total number of single pulses reaches a preset value. If so, end the process; if not, return to step (5).

[0051] In addition, there are many specific implementation methods and approaches of the present invention, and the above is only a preferred implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
