A physical factor output control method and device

Abstract

The invention provides an output control method and device for physical factors. The output control method includes the steps of substituting received oscillation parameters and pre-stored power calibration parameters corresponding to the oscillation parameters into a preset function, and calculating duty ratios of PWM pulses corresponding to power gears of a therapeutic apparatus; enabling the oscillation high-end power to serve as the oscillation peak value and the oscillation low-end power to serve as the oscillation valley value, and outputting PWM pulse signals according to a preset oscillation mode with the duty ratio of the PWM pulse corresponding to the current power gear so that a power control circuit can control an output device in a set therapy time to output the physical factors according to the PWM pulse signals. Due to the fact that the power is continuously changed within any interval between zero and the rated maximum power, the biological tissues of a patient are prevented from generating tolerance caused by constant energy of the physical factors, the human body tissues of the patient are prevented from being damaged by excessively-large energy of the physical factors, the requirements of illness states of different bodies and in different stages for the energy of the physical factors are met, and the therapy adjuvant effect of the therapeutic apparatus is improved.

Description

technical field [0001] The invention relates to the field of medical applications, and more specifically relates to a method and device for controlling the output of physical factors. Background technique [0002] At present, with the rapid development of the medical level, it has become the mainstream in this field to use various therapeutic instruments to assist in the treatment of some diseases. , so that it can generate light signals with fixed energy intensity, and irradiate relevant parts of the patient to assist in the treatment of acute and chronic diseases, neuropathic pain and dysfunction, such as acute and chronic injuries of the motor system, rheumatism, infection and non-infectious inflammation And skin diseases, etc., greatly shortening the treatment time of patients and reducing the pain of patients. [0003] However, in actual treatment, since the output of the light source generator is a continuous light signal or an intermittent light signal, its power is ...

Problems solved by technology

[0003] However, in actual treatment, since the output of the light source generator is a continuous light signal or an intermittent light signal, its power is constant, that is to say, the light energy irradiated to the diseased part of the patient The intensity is fixed. Therefore, after multiple treatments, it is easy for the patient's biological tissue system to develop tolerance to it, thereby affecting the therapeutic effect. The need for energy reduces the therapeutic effect, and even causes damage to the patient's body tissue due to the excessive intensity of light energy received at a certain stage
