Abstract
A composite tear detection bar includes a cotton wire and a detection filter paper. The cotton wire is connected to the detection filter paper and is disposed on a front end of the composite tear detection bar. The cotton wire is formed by a plurality of cotton threads. The detection filter paper is arranged on a back end of the composite tear detection bar. The composite tear detection bar is in the shape of a bar in whole. A scale line having length marks are disposed on the detection filter paper and a dyeing line, which is arranged in parallel with the scale line, is disposed at a back side of a connection position between the cotton wire and the detection filter paper. When tear detection is carried out, the cotton wire contacts ocular tissue of an patient so that stimulation on the ocular tissue of the patient is reduced and discomfort of the patient during the tear detection can be reduced. By means of the scale line on the detection filter paper, a doctor can carry out the tear detection more conveniently, intuitively and accurately. By means of the dyeing line disposed on the front end of the detection filter paper, a dyeing agent on the dyeing line spreads along with to-be-detected tear so that a front edge of wetting length of the tear can be clearly display. The composite tear detection can provide a reliable evidence for the doctor in diagnosis of diseases such as ophthalmologic tear secretion disorder and the like.
Description
Technical field
The present invention relates to the technical field that clinical ophthalmology detects, is a kind of by cotton thread with detect filter paper and be combined into specifically, not only overcome problem that ocular tissue is stimulated but also can be accurate and visual understand the compound tear detector bar of eye table secretion situation.
Background technology
For a long time, in the practice of medical matters circle clinical ophthalmology, to suffering from the eye disease patient of lacrimal secretion obstacle, all adopt band colorant tears detecting filter strip test lacrimal secretion, and by measuring the wet length of tear, obtain diagnostic result.Because filter paper bar has sharp edge, and material is harder, easily stimulates patient's ocular tissue, and especially each test will continue 5 minutes, brings uncomfortable and injury to patient.In recent years, the cotton thread that adopts cotton thread to prepare through the phenol red processing of PH indicator carries out lacrimal secretion detection and starts to enter clinical practice, and it is yellow that cotton thread is, and cotton thread has color stability and water absorbing capacity stability, is weakly alkaline tear and makes the yellow phenol red pink that becomes.When measurement, line end bending is folded in conjunctiva place inside patient's eyelid, measures the wet length of pink tear, only needs to draw test result tens of seconds.Cotton thread matter is soft and drain speed is fast, has both reduced stimulation and discomfort to patient's eye, can quick and precisely draw again diagnosis.But soft yielding because of cotton thread matter, line end bending and integrated straight be linear cannot be kept, be easily wound around direct use operating difficulties in bulk; And phenol red seepage after the moisture absorption, affects result of use and accuracy; In addition, due to the excessive velocities that cotton thread is measured, can not accurately reflect the secretion situation of intraocular tear.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of by cotton thread with detect filter paper and be combined into, not only overcome problem that ocular tissue is stimulated but also can be accurate and visual understand the compound tear detector bar of eye table secretion situation.
The technical scheme that the present invention takes for the technical matters existing in solution known technology is:
Compound tear detector bar of the present invention, comprise: cotton thread and detection filter paper, above-mentioned cotton thread interconnects with detection filter paper, cotton thread is arranged on the front end of above-mentioned compound tear detector bar, be combined into by multiply cotton thread, and detection filter paper is arranged on the rear end of above-mentioned compound tear detector bar, entirety is strip, detecting the scale mark that is provided with long measure on filter paper, and at the cotton thread chromonema parallel with scale mark with the rear side setting of the binding site of detection filter paper.
The present invention can also adopt following technical measures:
Described cotton thread is wound around stranded forming mutually by multiply cotton thread.
On described detection filter paper, be provided with " L " or " R " mark of distinguishing left and right, form one group with two compound tear detector bars of " L " or " R " mark respectively.
The scale mark span arranging on described detection filter paper is 25-40 millimeter.
Described chromonema is 1-3 millimeter apart from the distance of the section start that detects filter paper high scale line.
The flow velocity of tear on cotton thread is identical with the flow velocity of tear on detection filter paper.
Advantage and good effect that the present invention has are:
The front end of compound tear detector bar of the present invention is cotton thread, in the time carrying out tear detection, cotton thread contacts with patient's ocular tissue, reduce the stimulation to patient ocular tissue, patient's sense of discomfort when having reduced tear and detecting, detect on filter paper, arrange scale mark make doctor's detection more convenient, directly perceived, accurate.Detect filter paper front end chromonema is set, in use the coloring agent on chromonema go together with tested tear, can the wet long forward position of clear demonstration tear, and make tear detection more very clear, for the diseases such as diagnosis ophthalmology lacrimal secretion obstacle provide reliable foundation.
Brief description of the drawings
Fig. 1 is the structural representation of compound tear detector bar of the present invention.
Embodiment
Referring to drawings and Examples, the present invention will be described in detail.
Fig. 1 is the structural representation of compound tear detector bar of the present invention.
As shown in Figure 1, compound tear detector bar of the present invention, comprise: cotton thread 1 and detection filter paper 2, above-mentioned cotton thread 1 interconnects with detection filter paper 2, cotton thread is arranged on the front end of above-mentioned compound tear detector bar, be combined into by multiply cotton thread, and detection filter paper is arranged on the rear end of above-mentioned compound tear detector bar, entirety is strip, detecting the scale mark 3 that is provided with long measure on filter paper, and at front end, the cotton thread chromonema 4 parallel with scale mark with the rear side setting of the binding site of detection filter paper that detects filter paper.
Cotton thread 1 is wound around stranded forming mutually by multiply cotton thread, the flow velocity by multiply cotton thread control tear on cotton thread.
Detect on filter paper and be provided with " L " or " R " mark of distinguishing left and right, form one group with two compound tear detector bars of " L " or " R " mark respectively.Can in use distinguish the measured corresponding eye body of different composite type tear detector bar by left and right mark.
Detecting scale mark 3 spans that arrange on filter paper is 30 millimeters, is mobile the provide foundation of tear on filter paper.
The distance that chromonema 4 distances detect the section start of filter paper high scale line is 1 millimeter.Coloring agent in chromonema adopts uranin, tetrachlorotetraiodofluorescein sodium's salt or placenta indigo plant.
The flow velocity of tear on cotton thread is identical with the flow velocity of tear on detection filter paper, thereby ensures consistance and the accuracy of detection architecture.
The front end of compound tear detector bar of the present invention is cotton thread, in the time carrying out tear detection, cotton thread contacts with patient's ocular tissue, reduce the stimulation to patient ocular tissue, patient's sense of discomfort when having reduced tear and detecting, detect on filter paper, arrange scale mark make doctor's detection more convenient, directly perceived, accurate.Detect filter paper front end chromonema is set, in use the coloring agent on chromonema go together with tested tear, can the wet long forward position of clear demonstration tear, and make tear detection more very clear, for the diseases such as diagnosis ophthalmology lacrimal secretion obstacle provide reliable foundation.
