Abstract
The utility model relates to an orphthalmic clinic detecting supplies, in particular to a tears detecting filter paper strip, which is applied to detecting tear excretion obstacles caused by all kinds of diseases; the filter paper is a long strip shape with a circular shape in the front and a scale line with a length unit of minimeter, a folding trail with a triangle opening arranged in the beginning of the scale line, and the frond of the filter paper strip is provided with a dyeing line; for the front of the filter paper strip is circular, the eye tissues of sufferers can bear less simulative and uncomfortable sense in the clinic application; by adding a length scale, the detection of doctors can be more convenient, more direct and more precise; the triangle opening arranged at one end of the folding trail makes the length wetted by tear more regular and more convenient to be measured; the dyeing line arranged in the front of the filter makes the dyeing agent go together with the tear and clearly indicate the wetting front of the tear, thus making the tear detection more apparent and supplying reliable basis for the diseases such as tears excretion obstacles etc. to orphthalmic doctors.
Description
Technical field
The utility model relates to a kind of clinical ophthalmology and detects articles for use, relates in particular to a kind of tear and detects the filter paper bar, is applicable to the detection of the lacrimal secretion obstacle that various diseases causes.
Background technology
The tear that is used for clinical ophthalmology at present detects the filter paper bar and is strip, and its end is square, therefore easily stimulates patient ocular tissue to cause the sense of patient's ophthalmic uncomfortable when detecting.The no scale of filter paper bar itself needs the wet length with scale dipstick metering tear, complicated operating process during detection.Therefore problems such as existing filter paper bar also exists by hygrometric long irregular in application, and wet long forward position is not obvious have a strong impact on the accuracy of tear data determination.
The utility model content
Fundamental purpose of the present utility model is to improve above-mentioned deficiency, provides a kind of convenience easily to survey, the clinical ophthalmology tear detects the filter paper bar accurately.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of tear detects the filter paper bar, integral body is strip, it is characterized in that leading section is circular, it is the scale mark of long measure that this filter paper bar is marked with the millimeter, the parallel folding line of establishing of scale mark initiating terminal, folding line one side is provided with triangle notch, and establishes a chromonema at filter paper bar front end.
The utility model has the advantages that: in clinical ophthalmology is used, because this filter paper bar front end is made as circle, reduced pungency and sense of discomfort to patient ocular tissue, setting up the long measure scale mark, that the doctor is detected is more convenient, directly perceived, accurate.The triangle notch that folding line one side is provided with makes the wet calipers of tear then neatly be convenient to metering.The chromonema of filter paper bar front end makes the coloring agent on the chromonema go together with tested tear, can clear demonstration tear wet long forward position, and it is more very clear that tear is detected, for diseases such as diagnosis ophthalmology lacrimal secretion obstacle provide reliable foundation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1, the utility model ingredient synoptic diagram
1 leading section, 2 scale marks, 3 folding lines, 4 triangle notch, 5 chromonemas.
Embodiment
As shown in Figure 1, the utility model integral body is strip, width is 5mm, it is characterized in that leading section (1) is for circular, it is the scale mark (2) of long measure that this filter paper bar is marked with the millimeter, be generally 30～40mm, the parallel folding line (3) of establishing of scale mark (2) initiating terminal, be folded in eye when being convenient to detect, folding line (3) one sides are provided with triangle notch (4), and establish a chromonema (5) at filter paper bar front end, the coloring agent of chromonema (5) adopts uranin, tetrachlorotetraiodofluorescein sodium's salt or placenta indigo plant, behind the parallel initiating terminal of being located at long measure scale mark (2).During detection, filter paper bar folding line one end is inserted and put in the inboard 1/3 place's conjunctival sac of patient's palpebra inferior, the other end hangs from above in the palpebra inferior outside, and the wet long wet long forward position of going together with the coloring agent on the chromonema of tear is observed in the detection back on the filter paper bar, directly reads the wet long testing result of tear.For guaranteeing that operation is accurate and the medical archive preservation is errorless, can indicate L or R in filter paper bar lower end and use to distinguish right and left eyes.This tear detects the convenient easily survey, accurate of filter paper bar, not only alleviates the stimulation to patient ocular tissue, provides reliable foundation for the doctor carries out the science diagnosis simultaneously.
Claims (3)
1, a kind of tear detects the filter paper bar, and integral body is strip, it is characterized in that leading section is circular, it is the scale mark of long measure that this filter paper bar is marked with the millimeter, the parallel folding line of establishing of scale mark initiating terminal, folding line one side is provided with triangle notch, and establishes a chromonema at filter paper bar front end.
2, a kind of tear according to claim 1 detects the filter paper bar, it is characterized in that described scale mark length is 30～40mm.
3, a kind of tear according to claim 1 detects the filter paper bar, it is characterized in that the coloring agent that described chromonema adopts is uranin, tetrachlorotetraiodofluorescein sodium's salt or placenta indigo plant.
