Abstract
The utility model relates to an eyeglass frame type cornea diameter measurer which comprises a first eyeglass leg type measurer leg (1) and a second eyeglass leg type measurer leg (2), wherein the rear end of the first measurer leg (1) and the rear end of the second measurer leg (2) are bended downward. A beam (3) with degree scales is arranged between the front end portion of the first measurer leg (1) and the front end portion of the second measurer leg (2). A nose support (4) is arranged in the middle of the beam (3). A vernier (5) is arranged at the left side of the nose support (4) of the beam (3) in a sliding mode. A vernier (5) is arranged at the right side of the nose support (4) of the beam (3) in the sliding mode. The eyeglass frame type cornea diameter measurer has the advantages of being convenient to measure, accurate in results when the eyeglass frame type cornea diameter measurer is used for measuring the diameter of a cornea, capable of not only avoiding cumbersome steps and inconvenience of measurement of a special instrument, but also overcoming the defects that stability of holding a ruler by a hand is not enough and the measuring results are not accurate when the diameter of a cornea is visually measured with the ruler opposite to an eye of a person to be measured, simple in structure, and convenient to use. The person to be measured uses the eyeglass frame type cornea diameter measurer just like using an eyeglass, a doctor moves the two verniers to enable the two verniers to be respectively placed at the left side and the right side of a black eyeball, and numerical value of the diameter of the cornea is worked out according to the degree scales on the beam.
Description
Technical field
This utility model relates to medical equipment, is specifically related to a kind of corneal diameter measuring device.
Background technology
The ophthalmologist can adopt instrumentation to measure for the examinee measures corneal diameter, and measurement result accuracy is higher, but need to start instrumentation, and step is cumbersome, and is also inconvenient.The straightforward procedure that some ophthalmologists adopt is that this method is because hands is taken ruler stability not with the eyes range estimation corneal diameter of ruler facing to the examinee, and measurement result is not accurate enough.
Summary of the invention
The purpose of this utility model is to provide a kind of measurement convenience, result glasses posture corneal diameter measuring device accurately.
Technical solution of the present utility model is: it comprises leg of spectacles formula measuring device lower limb one and measuring device lower limb two curved under the rear end, be provided with the crossbeam with scale between the leading section of measuring device lower limb one and measuring device lower limb two, the middle part of crossbeam is provided with nose support, and on crossbeam, the left side of nose support and right side are slidably fitted with respectively two verniers.
Technique effect of the present utility model is: use its to measure corneal diameter and have the convenience of measurement, result advantage accurately.Both avoid using the step of instrumentation measurement cumbersome and inconvenient, also can avoid taking ruler stability inadequate with ruler facing to examinee's eyes range estimation corneal diameter hands the defective that measurement result is not accurate enough.It is simple in structure, and is easy to use, and the examinee wears use as glasses, and the doctor stirs two verniers and makes its left side that lays respectively at the black eye ball and right side, just can converse according to the scale on crossbeam corneal diameter numerical value.
Description of drawings
Fig. 1 is this utility model example structure schematic diagram.
The specific embodiment
As shown in drawings, it comprises leg of spectacles formula measuring device lower limb 1 and measuring device lower limb 22 curved under the rear end, be provided with the crossbeam 3 with scale 31 between the leading section of measuring device lower limb 1 and measuring device lower limb 22, the middle part of crossbeam 3 is provided with nose support 4, and on crossbeam 3, the left side of nose support 4 and right side are slidably fitted with respectively two verniers 5.
The upper end of vernier 5 is slidably mounted on crossbeam 3 upper and lower ends to having the perpendicular mark post 51 that is positioned at measured's cornea both sides when measuring.Nose support 4 is fixed on the below of crossbeam 3.The front end of measuring device lower limb 1 and measuring device lower limb 22 is hinged with the left and right sides of crossbeam 3 respectively and is can subtend folding.
Claims (4)
1. glasses posture corneal diameter measuring device, it is characterized in that: it comprises leg of spectacles formula measuring device lower limb one (1) and measuring device lower limb two (2) curved under the rear end, be provided with the crossbeam (3) of band scale (31) between the leading section of measuring device lower limb one (1) and measuring device lower limb two (2), the middle part of crossbeam (3) is provided with nose support (4), and left side and the right side of the upper nose support (4) of crossbeam (3) are slidably fitted with respectively two verniers (5).
2. glasses posture corneal diameter measuring device as claimed in claim 1, is characterized in that the upper end of described vernier (5) is slidably mounted on crossbeam (3) upper and lower end to having the perpendicular mark post (51) that is positioned at measured's cornea both sides when measuring.
