Description
Technical field
This utility model belongs to phototherapy apparatus technical field, specifically, and particularly a kind of UVA1 ultraviolet light PUVA.
Background technology
Ultraviolet light is widely used in skin treating, and concrete can treat the various dermatosiss such as psoriasis, vitiligo, alopecia, herpes zoster, pityriasis rosea, neurodermatitis, chronic eczema, lichen planus, cutaneous T cell lymphoma, chronic ulcer, specificity erythra, folliculitis, furuncle and phyma pain, microbic eczema, atoipc dermatitis, alopecia areata, acne and seborrheic dermatitis.
Ultraviolet light has a wide range of applications at department of dermatologry, and UVA1 light especially wherein penetrates deeplyer, and clinical practice is more extensive, and does not have carcinogenic risk through observation for many years, and safety is significantly higher than UVB light source.The conventional light source of these wave bands mostly is as metal-halide lamp, fluorescent lamp, laser etc.; There is the shortcomings such as the wide and energy attenuation of spectral region is too fast in metal-halide lamp wherein, for the wide optical filter that needs of spectral region, useless wavelength or harmful wavelength filtered, and the too fast light source consumptive material that directly caused of energy of light source decay, has increased cost greatly; The Output optical power density of fluorescent lamp is little, causes treatment time permanent, and therapeutic efficiency is low, and user experiences not good; LASER Light Source high cost is unfavorable for large-area treatment simultaneously, and for most of medical institutions, over-burden.The inferior positions such as these light sources more or less exist consumptive material, light source life is too short, power stability is not high, spectral region is wide, high cost; In addition,, in the time of large area treatment, the skin of different area for treatment exists significant difference to cause the problem for the treatment of deficiency or overmedication for the sensitivity of light.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of power stability is high, the uniform ultraviolet light therapeutic apparatus of optical power density.
The technical solution of the utility model is as follows: a kind of ultraviolet light therapeutic apparatus, comprise main frame (1) and the treatment cover (2) that at least one is connected with main frame (1), its key is: described treatment cover (2) is by shell (21), radiator (22), surface-mounted integrated circuit (23), reflex reflector lens (24) and protective cover (25) form, described shell (21) is the uncovered cover body structure in upper end closed lower end, open-mouth in shell (21) lower end is installed the protective cover (25) with ultraviolet light high-transmission rate, the top installation of heat radiator (22) of described shell (21) inner chamber, the bottom of shell (21) inner chamber is provided with a circle reflex reflector lens (24), the inwall of shell (21) is close to and is fixed on to described reflex reflector lens (24), in the described reflex reflector lens of a circle (24), be provided with surface-mounted integrated circuit (23), on this surface-mounted integrated circuit (23), be evenly distributed with some LED of series connection successively.
This utility model adopts LED as light source, has solved the problem of background technology light source deficiency.LED light source has the life-span that reaches 50,000 hours, and power stability is high, and optical power density is even; LED light source adopts DC source, start fast, need not preheating, spectral region can be good at being controlled in the scope of application, does not need additionally to increase optical filter, has greatly controlled equipment cost and use cost.
Because the required electrical quantity of LED light source is constant current source, therefore adopt series system to connect between different LED power supply.In the situation that supply current is constant, in treatment constant distance situation, optical power density output is certain, controls actual output dose by controlling fluorescent lifetime, therefore can only need a therapeutic dose for the parameter of controlling on operation interface.If optical power density is 100mw/cm
2, setting output dose is 100J, needs to irradiate 1000s.
Integrated LED light source is in series by multiple LED, and its object is the output that improves optical power density, and being different from traditional fluorescent lamp and metal-halide lamp only needs single source.Decide the arrangement tightness degree of LED according to the output of the optical power density of output and single LEDs.By controlling the distribution density of LED light source, solve the problem such as treatment deficiency or overmedication that exists significant difference to cause for the sensitivity of light because of different area for treatment, can precisely control the optical power density ratio of different parts, thereby guarantee the effect for the treatment of.
Radiator is that integrated LED light source dispels the heat, to guarantee that LED light source normally works.If LED light source excess Temperature, can cause the decay in its life-span, the going down of power, and the drift of wavelength.
Reflex reflector lens is looped around the inwall for the treatment of cover shell, its objective is the light being radiated on treatment cover inwall is all reflexed to treatment window direction, to improve the optical power density of output, has also reduced the temperature for the treatment of cover simultaneously.
Protective cover can prevent extraneous grieshoch on the one hand, on the other hand, can avoid the situation of touching light source in therapeutic process to produce, thereby guarantee therapeutic process safety, reliable.
Adopt this utility model to carry out in UVA1 treatment, the treatment of UVA1 is divided into low middle high third gear therapeutic dose, is followed successively by 6.5-20J/cm
2, 40-60J/cm
2, 100-130J/cm
2.In various clinical conclusions; conventionally can adopt high-dose therapy to improve therapeutic effect; treatment time is a key factor of restriction high-dose therapy; in order to improve user's Experience Degree; treatment time was controlled in 1 hour as far as possible; and a node conventionally weighing high dose is therapeutic dose 100J, required optical power density need to reach 27.7mW/cm
2above, for luminous power, output requires as 30mw/cm this utility model
2-150mw/cm
2.
UVA1 causes erythemal effect far below UVB and PUVA, and wavelength exceedes 360nm, substantially without causing erythemal effect, causes the direct side effect after treatment substantially not exist; According to the research of nearly 30 years, ultraviolet light was treated dermatosis again, and UVA1 is without any carcinogenic report, and this is different from PUVA and UVB, very safe.
