The invention discloses a photoirradiation head of a photodynamic therapy apparatus, which belongs to a device making use of phototherapy. The photoirradiation head comprises a high power density LED integrated module of certain central wavelength and optical power density as well as at least two high power density LED integrated modules which have different or identical central wavelength and the optical power density ranging between 30 and 200mw / cm2 and are connected in series or in parallel on a pedestal body with a water-cooling structure. The photoirradiation head of the photodynamic therapy apparatus adopting the design can output light with high power density and multiple central wavelengths to enlarge photoirradiation area on the basis of adequate optical power density; moreover, the photoirradiation head can be coordinated with photosencitizers of different absorption wavelengths when used to treat different skin diseases. The photoirradiation head does not need to replace LED photoirradiation heads repeatedly during therapy, expands therapeutic application range and reduces the work intensity of medical staff.
Description
technical field [0001] The invention relates to a phototherapy device, in particular to a photoirradiation head of a photodynamic therapy machine for treating skin diseases with photodynamic therapy. Background technique [0002] Photodynamic therapy is one of the effective means to treat skin diseases such as port wine stains, acne, genital warts and various skin tumors. At present, the light-emitting diode (LED) photoirradiation in clinical application mainly uses high-power, multi-wavelength The advanced LED light source, combined with photosensitizers that absorb light of different wavelengths, uses different fluorescence effects to find lesions of different degrees, so as to have a good therapeutic effect on diseases of different depths in the skin. [0003] At present, the treatment machine for clinical application generally adopts single-chip microcomputer to centrally control the power supply, output power, temperature, cooling system and data display of LED.
