Abstract
The utility model relates to a medical slit lamp microscope, in particular to an ophthalmic slit lamp microscope, which is provided with a pedestal. An upper part of th pedestal is provided with a light source device, an objective assembly and an ocular assembly. The pedestal is provided a handle. The objective assembly and the ocular assembly are arranged above the handle. The light source device comprises an LED light source arranged on the pedestal, a supporting cylinder arranged on the light source, and a reflecting prism arranged on the top of the supporting cylinder. The reflecting prism is positioned in front of an objective. By adopting a high-brightness white LED as the lighting source, the utility model has the characteristics of reasonable optical systems design, clear ophthalmic optic section, high brightness, light weight, convenient carrying and simple operation.
Description
Technical field
This utility model relates to a kind of medical slit lamp microscope, especially a kind of ophthalmic slit lamp microscope.
Background technology
Along with the continuous development of medical industry, particularly in this field of ophthalmology especially the development emphasis.In the 4 trillion yuan investment of expanding domestic demand, nearly hundred billion yuan of improvement that are specifically designed to the rural medical treatment condition are arranged, this means that homemade medical device industry will set foot in few rural market before will entering comprehensively.
Common to split desk-top slit lamp huge, and be defined in indoor carrying out, and the crowd who is fit to also is limited.In addition, light source adopts incandescent lamp bulb usually, and the caloric value height makes the microscope organism fever easily, and the illumination of electric filament lamp is also relatively stronger, makes the patient produce visual fatigue in the process easily.
Summary of the invention
In order to overcome the deficiency that above-mentioned traditional crack microscope exists, this utility model provides a kind of comparatively portable handheld slit lamp microscope.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of handheld slit lamp microscope, has base, the base top is provided with light supply apparatus and objective lens unit and eyepiece component, and base is provided with handle, and objective lens unit and eyepiece component are arranged on the top of handle; The carrying cylinder of the top that described light supply apparatus comprises the led light source that is arranged at base top, be arranged at light source and the reflecting prism that is installed on the carrying cylinder top are formed, and reflecting prism is positioned at the place ahead of object lens.
To the control of led light source light, further: described handle is provided with light and shade adjusting knob and the light switch of regulating light-source brightness for convenience.
For the detection and localization distance, guarantee the accuracy of testing result, further: the place ahead of described objective lens unit is set with volume holder support bar, controls distance between eyeball and the display device object lens by volume holder support bar.
In order to make overall structure lightly portable, more further: in the described base lithium battery is installed,, has saved power line, made things convenient for the adjustment of microscope position in hand-held use by lithium battery power supply.
This utility model passes through to adopt the high brightness white light-emitting diode as lighting source, reasonable optical system design, and the eye optical section is clear, the brightness height.Have characteristics in light weight, easy to carry, simple to operate, make things convenient for the go to the countryside ophthalmologic examination of special environments such as the consultation of doctors, optician's shop, forensic medical examination or field operations of doctor.Slit lamp microscope described in the utility model, the desktop function of structure function collection are all over the body, and the better depth of field, imaging processing more clearly, optics improves greatly, and the appearance of this product belongs to the level of leading domestic technology to adding a novel device again in the ophthalmology examination equipment.The developing of the ophthalmology clinic new projects of hospital not only can bring new growth engines to enterprise, can provide the whole people better portable medical services to society simultaneously.

The specific embodiment
A kind of handheld slit lamp microscope as shown in Figure 1 and Figure 2 has base 1, and base 1 top is provided with light supply apparatus 2 and objective lens unit 3 and eyepiece component 4, and base 1 is provided with handle 5, and objective lens unit 3 and eyepiece component 4 are arranged on the top of handle 5; The carrying cylinder 2-2 of the top that described light supply apparatus 2 comprises the led light source 2-1 that is arranged at base top, be arranged at led light source 2-1 and the reflecting prism 2-3 that is installed on carrying cylinder 2-2 top form, and reflecting prism 2-3 is positioned at the place ahead of objective lens unit 3.Described handle 5 is provided with light and shade adjusting knob 6 and the light switch 7 of regulating light-source brightness.Be set with volume holder support bar 8 in the place ahead of objective lens unit 3, lithium battery 9 is installed in base 1.
During use, grasp the handle 5 of slit lamp microscope, adjust the extension elongation of volume holder support bar 8, reach best detection position, opening light switch 7 makes led light source 2-1 begin illumination, the light of led light source 2-1 finally passes through the eyes that reflecting prism 2-3 shines patient by carrying cylinder 2-2, adopts led light source 1 illumination, and caloric value is low, cold light source, life-span is long, and stable performance is safe and reliable.The brightness of led light source 1 is adjusted control by the light and shade adjusting knob 6 on the handle 5.
