Abstract
A kind of compound tear detector bar, including: cotton thread and detection filter paper, above-mentioned cotton thread is connected with each other with detection filter paper, cotton thread is arranged on the front end of above-mentioned compound tear detector bar, it is combined into by multiply cotton thread, and detects filter paper and be arranged on the rear end of above-mentioned compound tear detector bar, generally strip, detection filter paper is provided with the graduation mark of long measure, and at cotton thread, the chromonema parallel with graduation mark is set with the rear side of the binding site detecting filter paper.When carrying out tear detection, cotton thread contacts with the ocular tissue of patient, reduces the stimulation to patient ocular tissue, the sense of discomfort of patient when reducing tear detection, arranges graduation mark on filter paper make the detection of doctor more convenient, directly perceived, accurate detecting.Detection filter paper front end arranges chromonema, and in use the stain on chromonema is gone together with tested tear, can clearly show the forward position of the wet length of tear, provides reliable foundation for diseases such as diagnosis ophthalmology lacrimal secretion obstacles.
Description
Technical field
The present invention relates to the technical field that clinical ophthalmology detects, a kind of by cotton thread and detection filter paper combination
Become, not only overcome the problem that ocular tissue is stimulated but also can be accurate and visual understand the compound tear detection of ocular secretion situation
Bar.
Background technology
For a long time, in medical matters circle clinical ophthalmology is put into practice, to suffering from the eye disease patient of lacrimal secretion obstacle, all use band
Coloring agent tears detecting filter strip test lacrimal secretion, and by measuring the wet length of tear, it is thus achieved that diagnostic result.Due to filter paper bar
Having sharp edge, and material is harder, easily stimulate the ocular tissue of patient, test to continue 5 minutes especially every time, to patient bring uncomfortable with
Injury.In recent years, use cotton thread through the phenol red cotton thread processing preparation of PH indicator carry out lacrimal secretion detection initially enter clinical should
With, cotton thread is yellow, and cotton thread has color stability and water absorption stability, makes in weakly alkaline tear that yellow is phenol red to be become
Pink.During measurement, line end bending is folded in inside patient's eyelid at conjunctiva, measures the wet length of pink tear, only needs tens of seconds
Clock can draw test result.Cotton thread matter is soft and drain speed fast, had both reduced the stimulation to patient's eye and discomfort, and again could
Quick and precisely draw diagnosis.But because cotton thread matter is soft yielding, line end bending and integrated straight linear cannot keep, easily be wound around,
Direct use operating difficulties in bulk；And phenol red seepage after the moisture absorption, affect using effect and accuracy；Further, since cotton thread measures
Excessive velocities, the secretion situation of ophthalmic tear can not be accurately reflected.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is combined into by cotton thread and detection filter paper, has both overcome eye
The problem of tissue stimulation can understand again the compound tear detector bar of ocular secretion situation accurate and visually.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
The compound tear detector bar of the present invention, including: cotton thread and detection filter paper, above-mentioned cotton thread interconnects mutually with detection filter paper
Connecing, cotton thread is arranged on the front end of above-mentioned compound tear detector bar, multiply cotton thread be combined into, and detect filter paper and be arranged on
State the rear end of compound tear detector bar, generally strip, detect the graduation mark being provided with long measure on filter paper, and
Cotton thread arranges the chromonema parallel with graduation mark with the rear side of the binding site of detection filter paper.
The present invention can also use techniques below measure:
Described cotton thread is mutually wound around stranded forming by multiply cotton thread.
" L " or " R " mark about differentiation it is provided with, be respectively provided with that " L " or " R " indicates two on described detection filter paper
Bar compound tear detector bar constitutes one group.
The graduation mark span arranged on described detection filter paper is 25-40 millimeter.
The distance of the section start of described chromonema distance detection filter paper high scale line is 1-3 millimeter.
Tear flow velocity on cotton thread is identical with tear flow velocity on detection filter paper.
The present invention has the advantage that with good effect:
The front end of the compound tear detector bar of the present invention is cotton thread, cotton thread and the eye group of patient when carrying out tear detection
Knitting and contact, reduce the stimulation to patient ocular tissue, the sense of discomfort of patient when reducing tear detection, on detection filter paper
Arranging graduation mark makes the detection of doctor more convenient, directly perceived, accurate.Detection filter paper front end arranges chromonema, in use chromonema
On stain go together with tested tear, can clearly show the forward position of the wet length of tear, make tear detection more very clear, for doctor
The diseases such as raw diagnosis ophthalmology lacrimal secretion obstacle provide reliable foundation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the compound tear detector bar of the present invention.
Detailed description of the invention
Referring to the drawings and embodiment the present invention will be described in detail.
Fig. 1 is the structural representation of the compound tear detector bar of the present invention.
As it is shown in figure 1, the compound tear detector bar of the present invention, including cotton thread 1 and detection filter paper 2, above-mentioned cotton thread 1 with
Detection filter paper 2 is connected with each other, and cotton thread is arranged on the front end of above-mentioned compound tear detector bar, multiply cotton thread be combined into, and
Detection filter paper is arranged on the rear end of above-mentioned compound tear detector bar, generally strip, is provided with length on detection filter paper
The graduation mark 3 of unit, and flat with graduation mark in the rear side setting of the binding site of the detection front end of filter paper, cotton thread and detection filter paper
The chromonema 4 of row.
Cotton thread 1 is mutually wound around stranded forming by multiply cotton thread, controls tear flow velocity on cotton thread by multiply cotton thread.
It is provided with " L " or " R " mark about differentiation on detection filter paper, is respectively provided with two that " L " or " R " indicate and is combined
Type tear detector bar constitutes one group.Can in use be distinguished measured by different composite type tear detector bar by left-right marker
Corresponding eye body.
Graduation mark 3 span arranged on detection filter paper is 30 millimeters, provides foundation for tear flowing on filter paper.
Chromonema 4 is 1 millimeter apart from the distance of the section start of detection filter paper high scale line.Stain in chromonema uses
Fluorescein sodium, tetrachlorotetraiodofluorescein sodium's salt or Placenta Hominis are blue.
Tear flow velocity on cotton thread is identical with tear flow velocity on detection filter paper, thus ensures to detect the consistent of structure
Property and accuracy.
The front end of the compound tear detector bar of the present invention is cotton thread, cotton thread and the eye group of patient when carrying out tear detection
Knitting and contact, reduce the stimulation to patient ocular tissue, the sense of discomfort of patient when reducing tear detection, on detection filter paper
Arranging graduation mark makes the detection of doctor more convenient, directly perceived, accurate.Detection filter paper front end arranges chromonema, in use chromonema
On stain go together with tested tear, can clearly show the forward position of the wet length of tear, make tear detection more very clear, for doctor
The diseases such as raw diagnosis ophthalmology lacrimal secretion obstacle provide reliable foundation.
