Abstract

The utility model relates to a four-finger holographic tester for testing microcirculation in the patient's nail fold, which mainly comprises a lighting system, a microscope system, an image acquisition system, and a computer, wherein, an adjustable LED illuminating ring is arranged beside the objective lens of the microscope to adjust the included angle of LED emission; a polarizing glass is arranged before the objective lens; the lighting system is a cold light source with an adjustable 250W tungstenhalogen lamp. After the LED illuminating ring is mounted, when the microscope works at a high magnification, the included angle of the LED can be adjusted to coordinate with the focal length of the microscope, so that the four-finger holographic tester for microcirculation in nail fold can adapt to the clinical lighting environment; when the microscope works at a low magnification, the lighting intensity required is lower; when the microscope works at a high magnification, the lighting intensity required is higher. The polarizing glass mounted before the objective lens can improve the imaging sharpness.

Description

Nail fold microcirculation four refers to holographic somascope

Technical field

The nail fold microcirculation four that this utility model relates to a kind of patient's of inspection nail fold microcirculation situation refers to holographic somascope, belongs to the Clinical Laboratory Medical Instruments.

Background technology

In recent years, medical circle all gives bigger concern to micro-cycle theory both at home and abroad, and it is also bigger to dispute on.By to nail fold microcirculatory variation observe out the change and the health evaluating of human physiological functions, all be the focus of dispute.Four refer to holographic inspection technique by what the inventor of present patent application proposed, it is the special variation of nail fold microcirculation, left and right sides forefinger, middle finger is the physiological reaction of Chinese medicine meridian-tri-jiao channel, it also is the neuro physiology specific manifestations of viscera, this just needs to observe the variation of the microcirculatory overall alignment of nail fold, also need to amplify the variation of observing blood vessel, carry out Flame Image Process by computer, splice complete nail fold microcirculation figure, to check right-hand man's middle finger, nameless microcirculation changes, binding pattern figure, as shown in Figure 1, with the distortion of blood vessel, mamillary, ooze out, the hemorrhage microcirculation that waits changes, carry out illness analysis, file and print image.Yet the still incompetent nail fold microcirculation four that satisfies above-mentioned requirements refers to holographic somascope on market at present.

Summary of the invention

The purpose of this utility model is to refer to the requirement of holographic inspection technique to instrument in order to satisfy four, provides a kind of nail fold microcirculation four with the big visual field, high power digital display micromirror systems and computer processing system to refer to holographic somascope.

The technical solution of the utility model is achieved like this, it mainly contains illuminator, microscopic system, shooting acquisition system and computer and forms, be characterized in, at an other adjustable ring-type LED illuminator, the adjusting LED outgoing angle of being equipped with of microscope objective; Before object lens, also be equipped with polariscope; Described illuminator is a cold light source that is equipped with 250W scalable halogen tungsten lamp.

After installing scalable ring-type LED illuminator additional, scalable LED angle is regulated to reach with the microscope focal length is collaborative when the microscope high power, make nail fold microcirculation four refer to that holographic somascope can satisfy the needs of clinical illumination variation; light requirement was according to little when little multiple was observed; light requirement is according to big during big multiple; house ornamentation polariscope before the object lens, improved the definition of imaging.

The specific embodiment

This utility model embodiment is further described in conjunction with the accompanying drawings.

By shown in Figure 3, the holographic somascope of nail fold microcirculation four fingers is made up of illuminator, microscopic system, shooting acquisition system and computer, is characterized in, is equipped with an adjustable LED Luminous Ring 4 on microscope objective 6 sides; Before object lens 6, also be equipped with polariscope 5; Illuminator is a cold light source that is equipped with scalable 250W halogen tungsten lamp.Illuminator is made up of the cold light source of optical fiber, optical fiber exit tube and 250W scalable halogen tungsten lamp.Microscopic system is that the change times stereomicroscope by commercially available band shooting mouthful improves, and is made up of the polariscope 5 that is equipped with before object lens 6, zooming system 7, prism 8, eyepiece 9 and the object lens 6.Object lens 2 *, zooming system 4 *, eyepiece 10 *, amplification 20 *-80 *.As microscope is big movable base, then it is changed into rocking handle and regulates.Shooting acquisition system 10 can adopt digital camera or DV, and element needs more than 1,000,000 mutually.By shown in Figure 2, a plurality of light emitting diodes (LED) 14 arranges along peripheral annular, and being equipped with iris aperture regulator 15,16 thereafter is power supply.Scalable LED angle is regulated to reach with the microscope focal length is collaborative when the microscope high power, the additional optical fiber incident illumination, scalable illuminance and flexible angle of incidence, make nail fold microcirculation four refer to that holographic somascope can satisfy the needs of clinical illumination variation; light requirement was according to little when little multiple was observed, and light requirement is according to big during big multiple.By the illuminator that the LED illumination encircles and 250W cold light optical fiber is formed, can solve the dead angle and the insufficient problem of illumination of existing instrument, be that the adjustable illumination of LED solves illumination dead angle and the not enough problem of part illumination, the optical fiber lighting device side is penetrated to be increased third dimension and strengthens the illuminance range of accommodation.Installing polariscope additional is under strong illumination, removes catoptrical veiling glare, increases definition.

When carrying out the observation of nail fold microcirculation with this instrument, as shown in Figure 3, the examinee is pointed 2 to be put on the finger carriage 1, coat artificial musk's pitch, open the cold light source 3 and the LED ring of light 4, choose suitable focal length and illuminance, two kinds of approach are observed, the one, observe by eyepiece 9, the 2nd, observe by computer 11 display 12, and available color printer 13 is printed.
