Test agent composition for dentistry

Disclosed is a test strip for measuring tear production. The test strip comprises a generally flat sheet material having one end rounded to be semi-circular shaped and being printed with a folding line along which said strip is bent prior to the measurement operation. The test strip is further printed with graduation marks and a scale for indicating the amount of absorbed tear. In a preferred embodiment, provided at either one or both corners of the end opposite to the rounded end is a mark indicating that the particular test strip is used for measuring one of either the left or right eye. The sheet material is preferably made of filter paper. The test strip has no notched portion which would weaken the sheet material and yet may be folded precisely along the fold line prior to use. The graduation marks and scales printed on the test strip enable easy measurement of the length of the portion wetted by tear fluid.

Test strip for measuring tear production

Process for measuring tear production

The present invention is a tear production measuring sheet that has a pair of measuring strips adapted to be used for the right and left eyes and is disposed side by side in such a manner that the strips have a common scale. Each of the measuring strips is separated from the measuring sheet by a cut formed in the measuring sheet so as to extend around the measuring strip, except for a connection between the measuring strip and the sheet.

Tear production measuring sheet and package therefor

A simplified detection implement for use in the biological or chemical tests such as medical, pharmaceutical, microbiological, enzymological or analytical tests comprising an adhesive sheet (1) having an adhesion material layer (4), the adhesion sheet (1) also having an area 'a' in an optimal shape and an area 'b' in an optimal shape with a folding line (6) at the border of areas 'a' and 'b'; a small test material (3) adhered to the adhesion material layer (4) and being placed approximately at the center of area 'a' of the adhesive sheet (1); and a peelable protection sheet (2) covering the surface of the adhesion material layer (4) and having an opening (5) big enough to expose the whole surface of the small test material (3) as well as being so positioned to expose the small test material (3) when areas 'a' and 'b' are overlapped by folding the adhesive sheet (1) at the folding line (6), and when areas 'a' and 'b' being overlapped the majority or part of area 'a' of the adhesive sheet (1) acts as the adhesive portion to a heating apparatus or heated body after the small test material (3) being such as added with reagent for detection, the small test material (3) being such as small test paper and being incorporated with substance to be tested therein or thereon at the time of testing.
