Abstract

Abstract 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), said 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, said 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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 181 words
A detection implement which comprises an adhesive sheet (1) having an adhesion material layer (4) as well as an area "a" of a round, square or any other optimal shapes and an area "b" of a round, square or any other 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 is placed approximately at the center of area "a" of the adhesive sheet (1); and a peelable protection sheet (2) covering the entire 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 area "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 a heated body.
Claim 2
Dependent Claim 181 words
A detection implement which comprises an adhesive sheet (1) having an adhesion material layer (4) as well as an area "a" of a round, square or any other optimal shapes and an area "b" of a round, square or any other 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 is placed approximately at the center of area "a" of the adhesive sheet (1); and a peelable protection sheet (2) covering the entire 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 area "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 a heated body.
Claim 3
Dependent Claim 22 words
A detection implement according to Claim 1 in which the adhesive sheet is colorless and transparent or colored and transparent or opaque.
Claim 4
Dependent Claim 24 words
A detection implement according to Claim 1 or 2 in which the small test material (3) is of a porous inorganic or organic substantce.
Claim 5
Dependent Claim 32 words
A detection implement according to Claim 1 or 2 in which the small test material (3) is a small test paper that contains or does not contain reagents for detection in advance.
Claim 6
Dependent Claim 46 words
A detection implement according to any one of the Claims 1, 2, and 3 in which a plurality of the small test material (3), adhesion material layer (4) and the transparent adhesive sheet (1) form a stack layer and also serially linked on the protection sheet(2).
Claim 7
Dependent Claim 27 words
A detection implement according to any of Claims 1 to 5 in which the protection sheet (2) is colorless semi-transparent or opaque or colored semi-transparent or opaque.
Claim 8
Dependent Claim 26 words
A detection implement according to any one of the preceding claims, in which the areas "a" and "b" of the adhesive sheet are cut off separately.
Claim 9
Dependent Claim 33 words
A detection implement according to any one of the preceding claims, in which the protection sheet possesses a break portion or break portions thereon that make ease to peel off said protection sheet.
Claim 10
Dependent Claim 29 words
A detection implement according to any one of the preceding claims, in which the area "b" possesses no adhesion material layer when area "b" being smaller than area "a".
