Abstract
A method for determining the radiation distance of a phototherapeutic apparatus features that two visual laser devices are obliquely installed at both sides of light source and the distance between said two laser devices can be calculated according to the distance between skin and phototherapeutic apparatus and the included angle between said two laser devices by tangent function.
Description
Technical field
The present invention relates to be used for the treating skin disease field, a kind of department of dermatologry particularly, the present invention relates to a kind of method of laser spacing and Phototherapeutic instrument that utilizes this method of adopting with the localized method and apparatus of irradiation distance in the Phototherapeutic instrument in Phototherapeutic instrument.
Technical background
Phototherapy is commonplace in the application of department of dermatologry.The patient need carry out the treatment of 6 to 8 weeks even longer time usually continuously, during phototherapy, distance between radiation source and the skin surface is far and near to be directly connected to the irradiance that skin surface skin lesion place receives and (to shine the luminous power on the unit are, unit: mW/cm2) just, the phototherapy curative effect is all relevant with exposure dose (product of irradiance and time) with side effect.
Therefore, in order to ensure curative effect with reduce the generation of untoward reaction, should guarantee that the skin lesion position accepts dose irradiation accurately, and then when requiring each irradiation, the necessary relative fixed of the distance of light source and skin lesion.
In fact, every kind of type phototherapy unit is all advised best irradiation distance, but the method for confirming irradiation distance seldom is provided, and this makes troubles for clinical practice.At present, existing people is installed in ribbon on the phototherapy unit, earlier ribbon is pulled out and is adjusted the distance between phototherapy unit and the illuminated position and realize spacing before irradiation; Yet this method is that a hard thing is touched on the skin inevitably, particularly when there are pus or other body fluid in the skin lesion place, can pollute or infect.
At present, the Phototherapeutic instrument that has adopted clinically generally is divided into three kinds, the flexible light guide Phototherapeutic instrument that comprises treatment small size or dispersion skin lesion, be used for the treatment of large tracts of land and concentrate the horizontal Phototherapeutic instrument or the vertical Phototherapeutic instrument of skin lesion, but the Phototherapeutic instrument of the sort of type no matter all exists can't make things convenient for and the defective of spacing exactly.
Summary of the invention
Given this, the object of the present invention is to provide a kind of Phototherapeutic instrument positioning irradiation distance, utilize this method, can make things convenient for and definite simply irradiation distance, only need visually just can determine whether to reach predetermined distance, and needn't contact damage skin.
For achieving the above object, the invention provides a kind of Phototherapeutic instrument positioning irradiation distance, may further comprise the steps:
1) in a Phototherapeutic instrument, two visible light semiconductor lasers is installed obliquely in the both sides of light source;
2) according to the distance between described Phototherapeutic instrument and the illuminated skin surface, and the angle between two laser instrument, utilize tangent trigonometric function relation to calculate two laser instrument distance therebetween, and described visible light semiconductor laser is fixed in the described Phototherapeutic instrument;
During use, vertically move the light source of Phototherapeutic instrument relative to illuminated skin, when the point of irradiation of two bundle laser on skin surface that sends when two visible light semiconductor lasers overlapped, then light source promptly was the irradiation distance of stipulating to the distance between the illuminated skin surface.
Preferably, described visible light semiconductor laser is made of laser diode.
Preferably, described two semiconductor lasers send HONGGUANG simultaneously, perhaps send green glow simultaneously, perhaps send one red one green light.
Preferably, the angle between described two semiconductor lasers is in 45 °～90 ° scopes.
Preferably, the angle between described two semiconductor lasers is 60 °.
Use method of the present invention, only utilize and estimate the irradiation distance whether distance that just can observe easily between light source and the illuminated skin surface reaches regulation, and in adjusting apart from process, Phototherapeutic instrument does not directly contact with damaged skin, thereby has avoided the danger of polluting or infecting.
In addition, also provide the multiple Phototherapeutic instrument that utilizes said method according to the present invention, these Phototherapeutic instrument spacings are convenient, can observe intuitively with range estimation, and are simple in structure, and can transform simply existing Phototherapeutic instrument, are fit to promotion and application.
Therefore, on the one hand, according to a kind of Phototherapeutic instrument of the present invention, a kind of flexible light guide Phototherapeutic instrument is provided, described flexible light guide Phototherapeutic instrument comprises a housing, in described housing, be provided with a light source that constitutes by flexible light-transmitting fibre, be set with two visible light semiconductor lasers obliquely so that have the angle that to select between the two described visible light semiconductor lasers in the both sides of described light source; Distance between the two described semiconductor lasers is calculated by tangent trigonometric function relation according to the size of distance between described Phototherapeutic instrument and the illuminated skin surface and described angle and is obtained; During use, vertically move the light source of Phototherapeutic instrument relative to illuminated skin, when the point of irradiation of two bundle laser on skin surface that sends when two visible light semiconductor lasers overlapped, then light source promptly was the irradiation distance of stipulating to the distance between the illuminated skin surface.
On the other hand, according to a kind of Phototherapeutic instrument of the present invention, a kind of horizontal Phototherapeutic instrument is provided, described horizontal Phototherapeutic instrument comprises the lamp box of a horizontal positioned, in described lamp box, flatly be provided with one group of medical special-purpose fluorescent tube to constitute radiation source, be set with two visible light semiconductor lasers obliquely so that have the angle that to select between the two described visible light semiconductor lasers in the both sides of described light source; Distance between the two described semiconductor lasers is calculated by tangent trigonometric function relation according to the size of the described angle of distance between described Phototherapeutic instrument and the illuminated skin surface and is obtained; During use, vertically move the light source of Phototherapeutic instrument relative to illuminated skin, when the point of irradiation of two bundle laser on skin surface that sends when two visible light semiconductor lasers overlapped, then light source promptly was the irradiation distance of stipulating to the distance between the illuminated skin surface.
