Abstract
The utility model discloses a bulbar conjunctiva microcirculation tester, belonging to medical instruments. The utility model comprises a cold light source with high color rendering, a photoconductive material, a cursor, a trimming mechanism of a cursor plane surface, a viewing lens, a condensing mirror, a head fixed frame, a stand, an adjustable mechanism with multiple degrees of freedom and a stereomicroscope. Because the cold light source with high color rendering is adopted, the instrument can treat headache and prevent and cure cerebrovascular disease by examining the bulbar conjunctiva microcirculation; the instrument can also be used to determine diseases through examining oral lips, tunica mucosa linguae and the nail fold microcirculations. The examining of the instrument has the advantages that the colour of the microcirculation blood vessels are real, the recurrent state of the blood and the shaped components in blood are clear and obvious, the source flow destination of the blood flow can be traced and observed easily.
Description
The bulbar Conjunctiva Microcirculation somascope belongs to the Medical Instruments technical field.
Microcirculation is the homergy of warrantor soma not only, keep the stable of human internal environment, but also participate in and finish the specific function of internal organs directly, thereby microcirculation has become very important in the many physiology of researching human body and pathological process and a phenomenon importance.The instrument that is used for microcirculation inspection aspect at present is used for lip, periglottis and nail fold position mostly, and mainly designs at the microcirculation inspection at nail fold position.Because the microcirculatory characteristics in nail fold position, its light intensity requirement to lighting source is higher, falls to penetrating transmitted light source in the formula in lighting system generally all adopts, in order to reduce in the lighting source infrared composition to being observed the influence of position temperature rise, so all take the optical filtering measure, thereby cause color rendering properties not good.And the color state of blood vessel is important indicator in the microcirculation inspection.In addition in microcirculation is checked, the incident angle of illuminating ray and incident direction are bigger to the observation effect influence, when especially multiple observation is greatly carried out efficiently at a certain position, blood capillary at the difference trend, the angle of incidence of light source and incident direction are just more outstanding to the influence of observation effect, and in fall to penetrating or the incident angle and the incident direction of interior transmitted light source fixing, just have influence on observation effect.
The purpose of this utility model is to provide a kind of movably bulbar Conjunctiva Microcirculation somascope of high-color rendering cold light source that has, to overcome the shortcoming of above-mentioned somascope.
This utility model is to realize like this.Adopt movably the high-color rendering cold light source to make lighting source, and increased the mode that condenser mirror reflection and light-guide material import, to adapt to the detection needs of various microcirculation indexs.For minimizing is observed fluctuation between position and the viewing lens, especially the needs checked of bulbar Conjunctiva Microcirculation have designed head fixed mount and cursor, thereby guarantee relatively stable between those who are investigated's eyeball and the viewing lens.
This utility model checks that owing to adopting the high-color rendering cold light source to make the blood vessel color is true, also because light source and condenser mirror position are adjustable, adds light-guide material, makes observation accurately; This utility model can check outside lip, periglottis and the nail fold that main can check bulbar conjunctiva simultaneously, because bulbar conjunctiva is poor transparent, scene is clear, white and the blood capillary of sclera color sets off, and red white contrast is clear, and blood reaches the wherein circulation of visible component and dynamically sees clearly easily; The blood vessel table exists, the easy tracing study of source and course whereabouts of blood flow; Can be observed all flow processs of blood (microcirculation).
Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of bulbar Conjunctiva Microcirculation somascope.
This somascope has high-color rendering cold light source 1, light-guide material 2, cursor 3, cursor plane of motion micro-adjusting mechanism 4, viewing lens 5, condenser mirror 6, head fixed mount 7, support 8, multiple degrees of freedom adjustable mechanism 9, stereomicroscope 10.Stereomicroscope is a continuous zoom, and it is fixed on the support by the multiple degrees of freedom adjustable mechanism.Viewing lens is installed in an end of stereomicroscope, because the microcirculation inspection is carried out under micro-condition, especially the microcirculation inspection of bulbar conjunctiva, the fluctuation that is observed between position and the viewing lens for minimizing is provided with an eye-catching cursor, in order to attract examiner's sight line, this cursor is fixed on the plane micro-adjusting mechanism, can change the position of observation like this by moving of cursor.Though can change observation position by adjusting stereomicroscope, because the bulbar conjunctiva surface curvature is bigger, the moving body stereomicroscope will cause the variation of focal length, especially when high-amplification-factor is observed, focal length variations brings influence more obvious, by moving cursor, by those who are investigated self regulate change observation the position, help microvascular tracking inspection.The high-color rendering cold light source is as: mercury lamp or the Halogen light handled through the cold light deielectric-coating, be positioned at the top of viewing lens, can move the angle of incidence and the incident direction that change illuminating ray, when especially high-amplification-factor observation is carried out at a certain position, at the blood capillary of different whereabouts, the angle of incidence of light source and incident direction are more outstanding to the influence of observation effect.For determining that better angle of incidence of light and incident direction are connected with light-guide material on the high-color rendering cold light source, as: optical fibers.Viewing lens below corresponding to the high-color rendering cold light source is equipped with condenser mirror, is equipped with the head fixed mount at support and the corresponding end of viewing lens, also is for preventing the fluctuation at tested position.
The utility model is to help analysing patient's condition by Analysis of Microcirculation in the meaning of medically using, the research and the new drug Research on the effect mechanism that are mainly used in preventing and treating cerebrovascular disease and treatment headache and are conducive to traditional medicine.
