Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
As shown in FIG. 1, the utility model provides a portable fluorescent amplification detection lamp, which comprises a vertical magnifier 1, a yellow filter 2 and a cobalt blue light source 3;
the eye side of the yellow filter 2 is superposed with the yellow filter 2; the cobalt blue light source 3 is a cobalt blue light emitter; the cobalt blue light source 3 is movably connected with the handle of the vertical magnifier 1 through the adjusting bracket.
In the present embodiment, the yellow filter 2 includes a filter and a metal frame; the periphery of light filter is located to metal crate, and metal crate's surface is equipped with the through-hole, and metal crate passes through the screw and realizes fixed connection with vertical magnifier 1's periphery, and the rotation around the screw is realized to yellow light filter 2 after the fixing.
In the embodiment, one end of the movable bracket 4 is clamped at the handle of the vertical magnifier 1, and the other end of the movable bracket 4 is clamped and fixed with the cobalt blue light source 3;
the movable bracket 4 comprises a magnifier clamping head, a first connecting rod 41, a second connecting rod 42 and a light source clamping head; the magnifier clamping head is clamped at the handle of the vertical magnifier 1, one end of the first connecting rod 41 is movably connected with the magnifier clamping head, the other end of the first connecting rod 41 is movably connected with one end of the second connecting rod 42, and the other end of the second connecting rod 42 is movably connected with the light source clamping head; the light source holder is clamped on the cobalt blue light source 3.
In this embodiment, the joints between the magnifier clamping head, the first link 41, the second link 42 and the light source clamping head are all fixed by bolts or bolts to form three movable joints, which is convenient for adjusting the position of the cobalt blue light source 3.
The use of the utility model is as follows: the method comprises the steps of dropping a drug at a drug loading end of the fluorescent nano-test paper into an eye of an observation target, then, adjusting a cobalt blue light source 3 to have an angle of 45 degrees to irradiate the observation target, wherein the wavelength range of blue light is about 424-455 nm, and then observing the condition of the eye of the target through a vertical magnifier 1 provided with a yellow filter 2, wherein the wavelength range of yellow light is 575-585 nm.
Specifically, the vertical magnifier 1 has the structure and the principle that: the vertical magnifier 1 is a convex lens that is kept at a fixed distance from the fixation target by a fixation bracket, and the common focal power is 24.00D-40.00D (standard magnification is 8X-10X). When the device is used, the fixation support is used for placing the fixation target at a micro distance within the focal length of the convex lens, so that the observation eye can see an enlarged and upright observation target virtual image. And (3) during detection, the edge of the object side bracket of the vertical magnifier 1 is attached and fixed on the orbit to be detected.
Fluorescein sodium test paper, Fluorescein sodium (Fluorescein sodium), also known as hydrated disodium Fluorescein sulfate. The diagnostic test paper is prepared by soaking, loading and drying a high-purity fluorescein sodium solution through filter paper. When the device is used, the contact lens eye moistening liquid is used for moistening the test paper medicine carrying end, the orange liquid indicator released by the test paper is dripped into the conjunctival sac of the eye to be detected, the eye closing of the eye to be detected is ordered for 1-2 min, and the detection and observation can be carried out after the surplus indicator is discharged. Sodium fluorescein test paper is commercially available in pharmaceutical shops.
Because blue and yellow are complementary colors, when the cornea and conjunctiva are irradiated by cobalt blue light, the reflected blue light of the observation field cannot penetrate through the yellow filter 2 due to the principle of spectral antagonism, so that the observation field forms a dark field, and the stained focus is easy to show under the condition of high contrast.
After being dyed by fluorescein sodium, the corneal injury is dyed into bright green under the support of dark background of the iris, the conjunctival injury is dyed into orange yellow under the support of porcelain white sclera, and the dyed tissue is observed by adopting a yellow filter 2, and because the light energy property of the yellow filter 2 only allows the light rays with green and yellow wavelengths to pass through, the injured focus of the cornea and the conjunctiva can be clearly captured.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
