Abstract

The invention relates to the technical field of medical treatment, in particular to a method and application of a semiconductor laser therapeutic instrument. The semiconductor laser therapeutic instrument is characterized in that a power-on key, a power-off key, a power selection key, a therapeutic opening key, a power indicating lamp, a therapeutic indicating lamp and a cell box are arranged on a shell; a micro-processing control circuit, a charging control circuit and a laser driving circuit are arranged in the shell; and the output end of a resistor R37 of the laser driving circuit, the collecting electrode of a triode Q31 and the port 10 of an operational amplifier U30 are respectively connected to a laser transmitter through three-core silk-covered wires. Compared with the prior art, the invention has the following advantages that: the semiconductor laser therapeutic instrument is managed with low power consumption, has an automatic power-off function and is in a low power consumption state after being powered off, and simultaneously, a system for power supply is switched to an external adapter for power supply during charging; and a constant-power regulating circuit regulates the output power by the unprocessed generated control signal to monitor the laser output power, and a negative feedback control mode is adopted, thereby achieving the constant output power.

Description

[technical field] [0001] The invention relates to the field of medical technology, in particular to a method of a semiconductor laser therapeutic instrument and its application. [Background technique] [0002] With the continuous development of human medicine, the requirements for the precision and accuracy of disease diagnosis and treatment are getting higher and higher. Lasers have attracted the attention of the clinical medical community because of their directivity and high intensity. Among them, the weak red laser with a wavelength of 650 nanometers is called the "golden band" of the human body by the world medical community. The latest laser medical research shows that when the 650-nanometer laser beam is vertically incident on the body and irradiates the radial artery from the body surface, about 1 / 10 The laser energy penetrates the skin, muscles and blood vessel walls and is absorbed by the blood. The blood fluorescence excited by the laser is mainly between 600-670 ...
