Abstract
A pupil distance measuring scale relates to the technical field of medical equipment and solves the technical problem of measuring the pupil distance. The measuring scale comprises a straight scale body, wherein the front surface of the scale body is provided with a left scale area, a middle scale area and a right scale area, and the back surface of the scale body is provided with viscosity; the middle scale area is positioned in the middle of the scale body, positioning scales are printed in the middle scale area and consist of an even number of positioning lines, each positioning line is divided into two groups in equal parts, the two groups of positioning lines are symmetrically distributed on the left side and the right side of the left and the right equal division lines of the middle scale area, and each positioning line inclines towards the left and the right equal division lines of the middle scale area from bottom to top; the left scale area and the right scale area are symmetrically arranged on the left side and the right side of the middle scale area, scales for measuring distance are printed on the left scale area and the right scale area, and the increasing direction of the scales is parallel to the length direction of the ruler body. The utility model provides a measuring scale, can be quick, convenient measurement interpupillary distance.
Description
Technical Field
The utility model relates to a medical equipment technique especially relates to a technique of interpupillary distance dipperstick.
Background
The trial of glasses all need measure interpupillary distance, and traditional interpupillary distance measuring method is with traditional ruler direct measurement, by the interval between optometrist's eye sight binocular pupil.
The pupil distance measurement mode has high requirement on the fitting degree of a patient, a measured person needs to visually observe a certain direction and keep for a certain time during measurement, and for children and nystagmus patients, the measurement is very difficult due to poor subjective fitting.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a requirement is low to patient's degree of coordination, can be convenient, accurate measurement relatively poor patient's interpupillary distance measuring scale of degree of coordination is provided.
In order to solve the technical problem, the utility model provides a interpupillary distance dipperstick, including the chi body of straight type, its characterized in that: the front surface of the ruler body is provided with a left scale area, a middle scale area and a right scale area, and the back surface of the ruler body is provided with viscosity;
the middle scale area is positioned in the middle of the scale body, positioning scales are printed in the middle scale area and consist of an even number of positioning lines, each positioning line is divided into two groups in equal parts, the two groups of positioning lines are symmetrically distributed on the left side and the right side of the left bisector and the right bisector of the middle scale area, each positioning line inclines towards the left bisector and the right bisector of the middle scale area from bottom to top, and the left bisector and the right bisector of the middle scale area are straight lines which divide the middle scale area into left and right halves;
the left scale area and the right scale area are symmetrically arranged on the left side and the right side of the middle scale area, scales for measuring distance are printed on the left scale area and the right scale area, and the increasing direction of the scales is parallel to the length direction of the ruler body.
Further, the ruler body is transparent as a whole.
The utility model provides a pupil distance dipperstick can the adhesion on the mirror holder to the nose central line is aimed at to the location scale in the scale district in the usable, through the picture of shooting, can directly see out the two eyes pupil distance on the picture, requires lowly to patient's degree of coordination, is particularly suitable for the relatively poor children of degree of coordination or eyeball tremble patient's pupil distance measurement.
Drawings
Fig. 1 is a schematic structural diagram of a pupil distance measuring ruler according to an embodiment of the present invention.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1, the embodiment of the present invention provides a interpupillary distance measuring ruler, including a straight ruler body, its characterized in that: the ruler body is transparent as a whole, the front side of the ruler body is provided with a left scale area, a middle scale area and a right scale area, and the back side of the ruler body is provided with viscosity;
the middle scale area 2 is positioned in the middle of the scale body, positioning scales are printed in the middle scale area 2 and consist of an even number of positioning lines 4, each positioning line 4 is divided into two groups in equal parts, the two groups of positioning lines 4 are symmetrically distributed on the left side and the right side of a left bisector A and a right bisector A of the middle scale area, each positioning line 4 inclines from bottom to top towards the left bisector A and the right bisector A of the middle scale area, and the left bisector A and the right bisector A of the middle scale area are straight lines which equally divide the middle scale area into a left half part and a right half part;
the left scale area 1 and the right scale area 3 are symmetrically arranged on the left side and the right side of the middle scale area 2, scales 5 used for measuring distance are printed on the left scale area 1 and the right scale area 3, and the growth direction of the scales 5 is parallel to the length direction of the ruler body.
The embodiment of the utility model provides a use together with the camera, its application method as follows:
let the patient wear the mirror holder of a pair no lens, paste the bridge of the nose position at the mirror holder with the back in the scale body in the scale district to then carry out the interval through each location line in scale district and patient's nose and compare accurately, make the equal bisector about the scale district and patient's nose central line coincide basically, the accurate mode is: two positioning lines positioned at the edge part of the bridge of the nose of the spectacle frame are bilaterally symmetrical relative to the left and right bisector of the middle scale area;
then, a camera is used for shooting an eye image of a patient, the distance between the left pupil and the right pupil and the central line of the nose is measured according to the scale values of the cornea reflecting points (two pupils) of two eyes on the left scale area and the right scale area in the shot image, so that the single-eye pupillary distance of the left eye and the single-eye pupillary distance of the right eye are obtained, and the distance between the left pupil and the right pupil and the central line of the nose is added, so that the pupillary distance between the two eyes can be measured.
