JPH021211A - Tear secretion amount measuring paper - Google Patents

Abstract

PURPOSE:To accurately measure the secretion amounts of tears of left and right eyes by providing not only folding display showing the folding part inserted in the lower eyelid but also numerical values and graduations for showing the secretion amount of tears and, if necessary, providing mark parts discriminating between left and right eyes to both left and right corner parts of a terminal part. CONSTITUTION:The leading end of filter paper 1 having a short strip shape as a whole is formed into a round shape to relieve the pain of an eye and folding display 2 is provided to the inside of the semicircular part of the filter paper 1 by a dotted line, a perforation or points, and graduations 3 and numerical values 4 are applied to the filter paper 1 from the part of the folding display 2. If necessary, mark parts 5 discriminating between left and right eyes are further provided to the left and right corner parts of the terminal of the filter paper 1 and one of the corners may be cut off in use according to left and right eyes. When this measuring paper is used, said paper is folded at the position of the folding display so as to be capable of viewing the numerical values and graduations and the folded part is inserted in the lower eyelid. After the elapse of a unit time, for example, after 5min, wetting of about 10-30mm is observed. This numerical value is easily read from the graduations and numerical values printed on the filter paper and becomes small as an age becomes high and, for example, at an age of 60 years old or more, said value is considerably reduced. Usually, a value of 5mm or less is judged to be abnormal.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This measuring paper is used in ophthalmology, and is used to measure the amount of lachrymal secretion within a unit time to detect abnormalities in the eyes, etc.

(Prior art) Schirmel test paper is known as this type of test paper, and it has a width of about 5 mm, a length of 42 rntn, and a semicircular tip, about 5 mm below the tip. 3 on one side
It has a rectangular hook notch, and how to use it is to fold the hook from the end, insert the semicircular part into the inner surface of the lower eyelid, and visually measure how much tear fluid has wetted the filter paper in a unit time. I was judging.

(Problems to be Solved by the Invention) In the above conventional product, the notch-like hook is bent at a portion and inserted into the inner surface of the lower eyelid, so if the hook is slightly bent, the hook may come into contact with the eyeball or the inside of the lower eyelid, causing pain. If the filter paper is felt or chipped, the convergence of the filter paper may be narrow and the paper may be cut during handling when wet, or it may be difficult to distinguish between the front and back sides, making it unclear which filter paper is on the left or right side of the eye. Relying only on visual measurements resulted in uncertainties, and there were many irregularities in the use of scales, which required measurements to be made precisely.

(Means for Solving the Problems) The present invention has a tanzaku-shaped filter paper that has a substantially semicircular tip, and has a folding indicator to indicate the folded part to be inserted into the lower eyelid, and a folding indicator to indicate the amount of lachrymal secretion. Numerical values and scales are provided, as well as marks on both the left and right corners of the end to distinguish between the left eye and the right eye.

(Function) When using the measuring paper of the present invention, fold it from the folded display position to the back side of the surface with numbers and scales, insert the folded part into the inside of the lower eyelid, and if the unit time is 5 minutes, for example, the normal residue is A wetness of 10 to 30 mm (usually about 15 mm) is observed, and it decreases with age and decreases considerably in people over 60 years old, but a wetness of 5 mm or less is considered pathological. This value can be easily read from the scale and numbers printed on the filter paper.

(Example) Next, a detailed description will be given with reference to embodiments shown in the drawings.

1 is a tanzaku-shaped filter paper with a semicircular tip, and on its surface, a folding indicator 2 is provided as a dotted line or dot from the semicircular side, and a scale 3 and a numerical value 4 are provided from this folding indicator 2. . Furthermore, a mark part 5 is provided at the left and right corners of the end.This mark part 5 can be used as a perforation as shown in FIG. Good too. Furthermore, mark 5 as shown in Figure 2 (A)
' and fill it in separately for left and right, or as shown in Figure 2 (B) (a mark 5' with a hole formed in one corner of either the left or right) can be used to mark left and right separately as shown in Figure 2 (C). It may also be used as a filter paper cut out in advance.

:' As shown in FIG. 3, the filter paper 1 is cut off at its end and connected through a cutting line 6, such as a mark or perforation, to form two sets corresponding to both the left and right eyes. It is also preferable to do so. In addition, the scale 3 and the numerical value 4 are, of course, printed using a printing method and printing ink that does not affect the amount of water absorption, that is, does not change the filter paper 1, such as a jet ink printer method. Black, red, blue, etc. are free, but does it blur in the water? ;5A
Substances that have properties such as color development or discoloration that can be easily recognized when wet with water and are added to this substance, such as fluorescent substances, include water-soluble substances such as fluorescein sodium, rhodamine, acrinol, etc. As for the blue one
Pharmaceutical coloring agents, such as No. 1, are themselves medicines, and are used as injections and disinfectants for the human body (phenol red, bioctanin blue I & other substances used, indicators used in clinical tests such as resazurin sodium, lidomas, bromothymol fluid, etc.). In addition, copper sulfate, copper chloride, and the like are also used as inorganic substances.

(Effects of the Invention) The present invention allows the filter paper to be folded accurately from the folding indication without any missing parts that weaken the filter paper, and to obtain precision in setting this point as the zero point of the scale, using a scale etc. 1) The amount of wetness can be read on a scale or numerical value, and it can also be determined without hesitation whether it is the left or right eye.
