Detailed description of the invention
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this description can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by detailed description of the invention different in addition, and the every details in this description also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.It should be noted that, when not conflicting, the feature in following examples and embodiment can combine mutually.
It should be noted that, the diagram provided in following examples only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
In the prior art, have and utilized ultraviolet light to carry out the equipment of disease therapy, such as see Fig. 1, show existing a kind of ultraviolet light therapeutic apparatus, comprise beam condensing unit 11, ultraviolet source 12, output window 13 and treatment window 14, wherein, described ultraviolet source is arranged in described beam condensing unit 11, the ultraviolet light that described ultraviolet source 12 produces is given optically focused and exports by described beam condensing unit, and described ultraviolet light exports treatment window 14 to, to treat through described output window.
In above-mentioned existing ultraviolet light therapeutic equipment, treatment window can be dismountable, and the shape for the treatment of window 14 also can change, and this is to adapt to various different treatment situation.But, in actual use, a protruding end 141 can be formed on treatment window end face, so that observe therapentic part during treatment (to refer to Fig. 2 and Fig. 3, wherein, Fig. 2 is the treatment window without protruding end, and Fig. 3 is the treatment window having protruding end).But in light treatment, need the optical property that consideration two is crucial, first is the collimation of light, and second is optical power density.Wherein, if the good light of collimation will be obtained, the good light source of general employing directivity in prior art, but its cost is too high; If provide optical power density so normally shorten treatment window and output window distance (also the distance namely shortened between light source and skin histology reaches and improves Output optical power density) or change the bore for the treatment of window.But, if provide optical power density by the distance shortened between light source and skin histology, so will treat window height and contradict with increasing for ease of observing therapentic part.
In order to overcome above-mentioned problems of the prior art, the present invention improves prior art, see Fig. 4 A, show the structural representation of a kind of ultraviolet light therapeutic apparatus of the present invention, described a kind of ultraviolet light therapeutic apparatus, comprise light source 42, beam condensing unit 41, light output window 43, optical alignment unit 45 and light treatment window 44, described light source 42 is arranged at the caustic surface side of described beam condensing unit 41, the side of described light output window 43 is connected with described beam condensing unit 41 and forms the enclosed space of a coated described light source 42 with described beam condensing unit 41, the opposite side of described light output window 43 is provided with described optical alignment unit 45 and described light treatment window 44 successively, and described light output window 43, become to be parallel to each other between optical alignment unit 45 and light treatment window 44.
Particularly, described light source 42 is ultraviolet source, and for generation of the treatment light of effective wave band, usually the treatment light of described effective wave band comprises ultraviolet light, and its wave-length coverage is 275nm-400nm.Certainly, also can adopt the monochromatic light in this ultraviolet wavelength range, such as wavelength is the Ultra-Violet Laser of 308nm and wavelength is the ultraviolet light of 308nm; Or wavelength be the UVA (English full name: UltraVioletA) of 320 ~ 400nm, the UVA1 (English full name: UltraVioletA1) of wavelength to be the UVB (English full name: UltraVioletB) of 275 ~ 320nm and wavelength be 340 ~ 400nm.Wherein, described light source 42 is non-point source.
Particularly, described beam condensing unit 41 is a parabola reflection shield, and for being exported according to same direction after reflecting by the treatment light be irradiated on it, usually, described light source 42 is arranged at the focus place of described parabola reflection shield.
Particularly, described light output window 43 is installed and is connected on described beam condensing unit 41, forms the enclosed space that includes light source 42, to protect light source 42 with beam condensing unit 41.Described light output window 43 simultaneously also can as sealing member, for the protection of the enclosed space at light source 42 place.
Particularly, described optical alignment unit 45 is corrected for carrying out collimation to the treatment light exported from light output window 43, exports even if treatment light is directional light.In the prior art, because light treatment window 44 can convert, therefore, when light treatment window 44 is highly inconsistent, there is a significant optical power density difference (height of light treatment window 44 is higher, and the optical power density of its treatment light exported is lower).In clinical practice, both needed a high optical power density to reduce treatment time, and also needed the window forming a protruding end 441 on light treatment window 44 end face simultaneously, be convenient to the observation to target tissue in therapeutic process.In the scheme of the invention described above, what optical alignment unit 45 was concrete can be cylindrical prism, cemented doublet group, convex mirror etc.It is for passing through optical alignment unit 45 by treatment light light beam larger for the angle of divergence, exports described treatment light light beam to be made the near-sighted collimation in directional light.Or the angle of divergence for the treatment of light light beam is diminished, to improve the collimation exporting light.Thus alleviate the distance difference that the light source 42 caused owing to converting light treatment window 44 arrives light treatment window 44 place, to reduce consequent optical power density difference.
More specifically, described optical alignment unit 45 can be the combination of one group of lens or multiple lens.Because light source 42 is non-point source, adopt multiple lens combination can obtain better collimating effect.But be photographed cost control, and working service, better is that employing optical element is as beam collimation.Such as, optical alignment unit 45 adopts plano-convex post lens to carry out the collimation for the treatment of light light beam to correct, and as shown in Figure 4 B, Fig. 4 B is the schematic diagram utilizing plano-convex post lens to carry out the beam collimation for the treatment of light to correct.Greatly improved by the collimation performance of light beam after plano-convex post lens, well solve, the shortcoming that the optical power density caused when output window protrudes significantly declines.
For example, see Fig. 4 C-Fig. 4 E, treatment window and treatment window base are square, and setting output window area is L3
2, treatment window base area is L
2, and setting whole shadow surface Light distribation even (have ignored the optical power density influence factor of beam condensing unit reflection), total Output optical power is W.
In figure 4 c, the dull and stereotyped output window of employing, its output window area is L3
2, light is uniformly distributed and is radiated at L
2area in, then actual is W* (L3/L) by the luminous power of output window
2.
In fig. 4d, employing be convex output window, add the distance of output window, its output window area is L3
2, light is uniformly distributed and is radiated at (L+L1)
2area in, then actual is W* [L3/ (L+L1)] by the luminous power of output window
2.
In Fig. 4 E, employing be convex output window, add the distance of output window, owing to having colimated light system before output window, think export light be essentially directional light, its output window area is L3
2, light is uniformly distributed and is radiated at (L+L1)
2area in, then actual is W*W* (L3/L) by the luminous power of output window
2.
After have employed colimated light system, convex output window, increases the distance of its output window, and its luminous power by output window is basic consistent with the luminous power of dull and stereotyped output window.
Further, see Fig. 4 F, show the another kind of structural representation of a kind of ultraviolet light therapeutic apparatus of the present invention, as illustrated in figure 4f, it is except having the structure of the described ultraviolet light therapeutic apparatus in Fig. 4 A, filter unit 46 is also provided with in described ultraviolet light therapeutic apparatus, after being installed on light output window 43, what described filter unit 46 was concrete can adopt bandpass filter, wherein said bandpass filter is divided into long wave pass filter again, short wave pass filter and narrow band pass filter, can by long wave pass filter, in short wave pass filter and narrow band pass filter, any one is for as described filter unit 46, or long wave pass filter, combination between short wave pass filter and narrow band pass filter forms described filter unit 46.
In addition, after adding filter unit 46, light output window 43 can be set, also namely can replace described light output window 43 with described filter unit 46.So, on the basis of the above, also can provide a kind of ultraviolet light therapeutic apparatus, comprise light source 42, beam condensing unit 41, filter unit 46, optical alignment unit 45 and light treatment window 44, described light source 42 is arranged at the near-end of the caustic surface side of described beam condensing unit 41, the far-end of the caustic surface side of described beam condensing unit 41 sets gradually described filter unit 46, optical alignment unit 45 and light treatment window 44, and becomes to be parallel to each other between described filter unit 46, optical alignment unit 45 and light treatment window 44.
Or, in Figure 4 A, light output window 43 can be integrated into parts with filter unit 46 and implement, concrete using bandpass filter as output window, i.e. filter unit 46 and the public optics of light output window 43.
Particularly, below by the treatment light how to obtain 295nm-320nm wave band, the scheme of filter unit 46 is adopted to be described in above-mentioned Fig. 4 F.See Fig. 5, show without before optical filtering, the spectrogram of the treatment light obtained.
If adopt narrow band pass filter as filter unit 46, it can allow the light of a certain wave band to pass through, and such as permission wavelength is that the light wave of 295nm-315nm passes through, and other wavelength all ends, and specifically sees Fig. 6 A; Can certainly be that the light wave allowing for 300nm-315nm passes through, other wavelength cut-off, be specifically shown in Fig. 6 B.Narrow-band-filter chip architecture is simple, and an eyeglass can reach the object of spectrum screening.
Further, if adopt bandpass filter as filter unit 46, concrete can be carries out transmission for the wavelength of below 320nm, and carries out ending (being expressed as 320nm-for this kind of bandpass filter) for the wavelength of more than 320nm.For the use of bandpass filter, the mode of 320nm-and 295nm+ can be adopted to export to the wavelength chooses realized between 295nm-320nm, see Fig. 7.But because the absorbance of bandpass filter is relatively on the low side, usually below 90%, and too level and smooth by the curve of wavelength intersection, usually there is more than 15nm transition wave-length.Concrete shows as: as the bandpass filter of 320nm-, the absorbance of more than 330nm is 1%; The absorbance of the absorbance at 320nm place to be the absorbance at 50%, 315nm place be 85%, below 310nm wavelength is 98% etc., and the connected applications of long-pass and short-pass just can reach good spectral filtering effect.
Particularly, under the therapeutic equipment adopting UVB light source, in its bandpass filter adopted, narrow band pass filter has good optical characteristics, and absorbance is high.The selection adopting plating deielectric-coating mode to realize spectrum exports, and is usually used in Laser output eyeglass.Narrow band pass filter can well bandwidth limit, and concrete exports the spectrum between 305nm-315nm as selected, and also optionally can export the spectrum between 395nm-320nm.Its difficulty of processing of narrow band pass filter is high, and cost is high.Therefore, in patent of the present invention, in order to reduce equipment cost further, the mode of two groups of bandpass filters can also be adopted to carry out combinationally using to realize the function of narrow band pass filter.Concrete can reach its object for long wave pass filter and short wave pass filter conbined usage.
Carry out long wave pass filter and short wave pass filter conbined usage to form the concrete scheme of filter unit 46 is:
First, the effect of long wave pass filter is, be make wavelength more than calibration value can by optical filter continue propagate, wavelength being absorbed by optical filter and can not well transmit below calibration value, sees Fig. 7 A.
In like manner, the effect of short wave pass filter is, be make wavelength below calibration value can by optical filter continue propagate, wavelength being absorbed by optical filter and can not well transmit more than calibration value, sees Fig. 7 B.
So, long wave pass filter can be installed on close to sources 42 end, short wave pass filter is installed on distance light source 42 end.Such as, the optical filter parameter of setting long-pass is that more than 295nm wavelength can be through, and below 295nm wavelength is by output; Short wave pass filter parameter is that below 320nm wavelength can be through, and more than 320nm wavelength is by output.So, the treatment light of 295nm-320nm wave band can be obtained, see Fig. 7 C.
In addition, described bandpass filter is dielectric coating filter.Because dielectric coating filter adopts the principle of film interference, carries out machining medium film to substrate, in order to ensure better penetrance, usually adopt quartz glass as substrate.But, bandpass filter also can adopt colour glass filter, namely in optical filter, adds absorbing medium, absorbs wavelength, and its feature is with low cost.Due in UVB treatment, the spectral range of 295nm-320nm is narrower, and colour glass filter is usually gone up and can not be realized the high requirement of precision, adopts dielectric coating filter as spectrum selectivity optical filter in the present invention.
Further, in UVA1 therapeutic equipment, adopt bandpass filter can realize good optical electivity and export.As the light source that spectral region is between 310nm-395nm, in order to ensure that output light source is UVA1, need interpolation long wave pass filter, the concrete long wave pass filter as added a 345nm+, light source just can well be selected to export as 345nm-395nm, avoid the radiation parameters of other wavelength.In UVA1 treatment, 340nm-400nm spectral region is comparatively wide, adopts coloured glass or dielectric coating filter all can meet instructions for use and don't significantly increase cost.
In sum, the present invention carries out filtering screening by the filter unit 46 in ultraviolet light therapeutic apparatus to the light that light source 42 produces, to obtain light that is that do not contain harmful wave bands or that there is side effect, and the optical alignment unit 45 relied on carries out collimation to exported light to be exported, well solve and treat at light shortcoming window 44 increasing optical power density that protruding end 441 causes and significantly decline.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
