Abstract

A technique is provided, which makes it possible to easily judge whether or not an analysis tool to be used for an analysis process for a sample is authentic and which makes it possible to secure the reliability of an analysis result thereby. An identification apparatus for identifying an analysis tool having a reagent portion to be used for an analysis process for a sample is provided, wherein the analysis tool further includes an identifying marker portion which is formed by using an invisible substance, the identification apparatus comprising a light emitter which emits a light toward the identifying marker portion, a light receiver which receives a light emitted by the invisible substance for forming the identifying marker portion exposed with the emitted light emitted by the light emitter, and an identification unit which identifies the analysis tool on the basis of a light-receiving result obtained by the light receiver.

Claims

1. An analysis tool having a reagent portion to be used for an analysis process for a sample, the analysis tool comprising:

an identifying marker portion which is formed by using an invisible substance.

2. The analysis tool according to claim 1, wherein the identifying marker portion is formed by using a fluorescent substance which emits fluorescence by using an ultraviolet ray as an exciting light.

3. The analysis tool according to claim 2, wherein:

the identifying marker portion is provided on a front surface or a back surface of a base member; and

at least an area of the base member, in which the identifying marker portion is provided, is formed of a material through which the ultraviolet ray is not transmitted and through which the fluorescence emitted by the fluorescent substance is transmitted.

4. The analysis tool according to claim 2, wherein:

the identifying marker portion is provided while being embedded in a base member; and

a portion disposed on a side of one surface is formed of a material through which the ultraviolet ray is transmitted and a portion disposed on a side of the other surface is formed of a material through which the ultraviolet ray is not transmitted and through which the fluorescence emitted by the fluorescent substance is transmitted, with a boundary disposed at an embedding position of the identifying marker portion in a thickness direction of the base member in at least an area of the base member in which the identifying marker portion is embedded.

5. The analysis tool according to claim 1, wherein identification information about the analysis tool is recorded by using the invisible substance on at least a part of the identifying marker portion.

6. The analysis tool according to claim 5, wherein the identification information includes at least any one of product specification information about the analysis tool and analysis-related information to be used when the analysis process is performed for the sample.

7. An identification apparatus for identifying an analysis tool having a reagent portion to be used for an analysis process for a sample, wherein:

the analysis tool further includes an identifying marker portion which is formed by using an invisible substance, the identification apparatus comprising;

a light emitter which emits a light toward the identifying marker portion;

a light receiver which receives a light emitted by the invisible substance for forming the identifying marker portion exposed with the emitted light emitted by the light emitter; and

an identification unit which identifies the analysis tool on the basis of a light-receiving result obtained by the light receiver.

8. The identification apparatus according to claim 7, wherein:

the identifying marker portion is formed of a fluorescent substance which emits fluorescence by using an ultraviolet ray as an exciting light;

the light emitter emits the ultraviolet ray; and

the light receiver receives the fluorescence emitted by the fluorescent substance for forming the identifying marker portion.

9. The identification apparatus according to claim 8, wherein:

the identifying marker portion is provided on a front surface of a base member of the analysis instrument;

at least an area of the base member, in which the identifying marker portion is provided, is formed of a material through which the ultraviolet ray is not transmitted and through which the fluorescence emitted by the fluorescent substance is transmitted;

the light emitter emits the ultraviolet ray from a side of the front surface of the base member; and

the light receiver receives the fluorescence transmitted through the base member on a side of a back surface of the base member.

10. The identification apparatus according to claim 8, wherein:

the identifying marker portion is provided while being embedded in a base member of the analysis instrument;

a portion disposed on a side of one surface is formed of a material through which the ultraviolet ray is transmitted and a portion disposed on a side of the other surface is formed of a material through which the ultraviolet ray is not transmitted and through which the fluorescence emitted by the fluorescent substance is transmitted, with a boundary disposed at an embedding position of the identifying marker portion in a thickness direction of the base member in at least an area of the base member in which the identifying marker portion is embedded;

the light emitter emits the ultraviolet ray from the side of the one surface of the base member; and

the light receiver receives the fluorescence transmitted through the base member on the side of the other surface of the base member.

11. The identification apparatus according to claim 7, wherein identification information about the analysis tool is recorded by using the invisible substance on at least a part of the identifying marker portion.

12. The identification apparatus according to claim 11, wherein the identification information includes at least any one of product specification information about the analysis tool and analysis-related information to be used when the analysis process is performed for the sample.

13. An analysis apparatus comprising the identification apparatus as defined in claim 7, wherein the analysis process is performed for the sample by using the analysis instrument identified by the identification apparatus.

14. An analysis apparatus for performing an analysis process for a sample by using an analysis tool having a reagent portion, wherein:

the analysis instrument has an identifying marker portion which is formed by using an invisible substance, the identifying marker portion having at least a part thereof on which analysis-related information to be used when the analysis process is performed for the sample is recorded, and the analysis apparatus comprising;

a light emitter which emits a light toward the identifying marker portion;

a light receiver which receives a light emitted by the invisible substance for forming the identifying marker portion exposed with the emitted light emitted by the light emitter;

an identification unit which identifies the analysis tool on the basis of a light-receiving result obtained by the light receiver;

a storage unit which acquires the analysis-related information on the basis of the light-receiving result obtained by the light receiver and which stores the acquired analysis-related information;

a measuring unit which measures the sample located on the reagent portion of the analysis tool; and

a calculating unit which calculates numerical information in relation to a specified component contained in the sample on the basis of a measurement result of the sample measured by the measuring unit and the analysis-related information stored by the storage unit.
