Description
Technical field
The utility model relates to acquisition device more particularly to a kind of acquisition devices.
Background technique
The related pigmented dermatosis such as traditional inspections and examinations leucoderma, psoriasis, amelanotic nevus, pityriasis rosea is domestic often
It is wood's lamp.Mr. Wood in 1903 removes visible light with a kind of nickeliferous glass for the first time from radiation beam, to be born
Contain only the filter of ultraviolet harness.Hereafter, the lamp of this filtration ultraviolet light is named as wood's lamp with his name by people,
Mr. Wood is named as the father of wood's lamp.Since wood's lamp only contains ultraviolet light therefore the ultraviolet radiator that is otherwise known as, ultraviolet light can
It is divided into 3 wave bands: UVC(180-290nm), UVB(290-320nm), UVA(320-400nm) and, since UVA wave band naked eyes are seen not
See, so being known as " black light area ".Wherein wood's lamp is exactly the ultraviolet light using UVA wave band.
Tissue is made of protein, nucleic acid and lipids, containing fluorescing and not fluorescent pigment, not
Under conditions of adding photosensitizer, biological tissue's stimulated luminescence irradiates and generates fluorescence, the characteristic that fluorescence has: (1) absorbing light (2) and protect
Holding the minimum intensity (5) in exciting light of intrinsic fluorescent characteristic (3) wavelength of fluorescence > excitation wavelength (4) fluorescence intensity has different journeys
Decaying (6) fluorescence intensity of degree depends on intensity, checking matter concentration and the fluorescence efficiency of exciting light.UVA is used using this characteristic
The ultraviolet lighting of wave band is mapped on skin, it is easy to and it is scattered or is reflected by epidermis, and the melanocyte and corium of epidermis and corium
Collagen can absorb this light wave, and nonspecific fluorescence is issued, based on blue white light.The autofluorescence of normal skin tissue
Depend primarily on epidermis colour of skin cellulose content, the composition of the fluorescence such as elastic fibers, collagenous fibres or pigment precursor and product.Different skins
It is different that skin tissue, different cases change generated fluorescence color.
The pigmentosa skin disease such as country's medical institutions' dermatologist's clinical examination at present and diagnosis leucoderma, psoriasis
Traditional Wood lamp & lantern product is mainly used, this kind of product is usually pure optical lens additional peripheral annular lamp tube or LED
Lamp bead light source achievees the purpose that observation, is merely able to accomplish to shoot the image observed by visually carrying out observation
And carry out quantitative analysis purpose.
It with the immediate technical solution of the utility model is applied and is awarded by Nanjing Bei Ning Medical Devices Co., Ltd.
The patent of power: wood's lamp imaging and analysis system, the patent No.: 201320002255.2.The patent is mainly by video camera, ultraviolet light
Source, it is as follows that bracket forms its function declaration: the image of video camera captured in real-time is transferred to computer by data line and passes through prison
Visual organ shows, saves and analyzes, the manually controllable adjusting of ultraviolet source brightness.Vidicon image needs solid using bracket
It is fixed, video camera can manual focusing, can also additional focusing handle focus.Product advantage: 1, this product can connect computer simultaneously
It is shown by liquid crystal display；2, the ultraviolet source brightness of this product can be adjusted by external device.Product disadvantage: 1, this product
