Multi-wavelength laser optical power density automatic control system for diabetic foot treatment

Abstract

The invention provides a multi-wavelength laser optical power density automatic control system for diabetic foot treatment. The multi-wavelength laser optical power density automatic control system comprises a control circuit, a driving circuit, light sources, wavelength selection modules, a dodging module, a spectrometer, a photoelectric detector, an image scanning module and an image recognition module. The image scanning module scans diabetic feet to form image data, and the image recognition module performs recognition and region division on the image data and determines the treatment light wavelength and optical power density required by each region according to the result of region division; the required treatment light wavelength value and optical power density value are input through the control circuit, the driving circuit drives the corresponding light source to emit light according to the optical power density value required by each region, the corresponding wavelength selection module outputs treatment light of the corresponding wavelength, and the treatment light passes through the dodging module and then uniformly irradiates the surface of the corresponding region to be treated; and the spectrometer and the photoelectric detector acquire the light wavelength and the optical power density in real time and feed back the light wavelength and the optical power density to the control circuit, and closed-loop feedback control of the light wavelength and the optical power density is completed through PID control.

Description

technical field [0001] The invention relates to a multi-wavelength laser light power density automatic control system for diabetic foot treatment, which belongs to the technical field of medical devices. Background technique [0002] At present, most of the therapeutic instruments for diabetic foot used in the market are red light therapeutic instruments. When the light emitted by these therapeutic instruments irradiates the skin of the body, the skin at different angles receives different optical power densities, especially within the range of the lesion treatment area. When the change is large, such as diabetic foot, the irradiation spot cannot vertically irradiate the skin at different angles at the same time, and the optical power density obtained by the skin in the treatment area varies greatly, which affects the treatment effect. In addition, the output wavelength of the existing phototherapy equipment is single, and the dose-effect relationship between the disease and...

Problems solved by technology

[0002] At present, most of the therapeutic instruments for diabetic foot used in the market are red light therapeutic instruments. When the light emitted by these therapeutic instruments irradiates the skin of the body, the skin at different angles receives different optical power densities, especially within the range of the lesion treatment area. When the change is large, such as diabetic foot, the irradiation spot cannot vertically irradiate the skin at different angles at the same time, and the optical power density obtained by the skin in the treatment area varies greatly, which affects the treatment effect

In addition, the output wavelength of the existing phototherapy equipment is single, and the dose-effect relationship between the disease and the light source is not clear, and the treatment band cannot be changed in time according to the needs of the patient's condition to ensure that the patient can receive effective treatment in a timely manner; in addition, the existing phototherapy equipment has a large output light parameter It is an open-loop control method, which cannot ensure that the light parameters are evenly and stably irradiated to the human lesion area, which reduces the therapeutic effect of the phototherapy instrument.
