Abstract

The present disclosure relates to a gel-phase patch that performs a function of assisting in staining during a staining process such as a process of coming into contact with a specimen such as blood to perform a staining function of staining the specimen, a process of fixing the specimen, or a process of forming an optimal pH at a specimen stained by a staining sample. According to an aspect of the present disclosure, a contact-type staining patch includes a staining solution that reacts with a specimen and a gel receptor provided as a gel matrix of a mesh structure in which a pore that accommodates the staining solution is formed and the mesh structure prevents the staining solution in the pore from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer some of the staining solution to the specimen.

Claims (54)

1. A test kit comprising:

a contact-type staining patch comprising:

a staining solution having a detection inducing substance configured to react with a specimen;

a gel receptor provided as a gel matrix of a mesh structure in which a plurality of pores that contains the staining solution is formed and the mesh structure is configured to prevent the staining solution in the plurality of pores from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer the detection inducing substance to the specimen, wherein the transferred detection inducing substance reacts with the specimen;

a patch plate storing the contact-type staining patch; and

a specimen plate that is configured to receive the specimen;

wherein relative rotational positioning between the patch plate and the specimen plate causes the specimen, when received by the specimen plate, to react with the detection inducing substance.

2. The test kit of claim 1 , wherein:

the staining solution includes the detection inducing substance configured to react with the specimen and a solvent configured to create a reaction condition of the detection inducing substance; and

the gel receptor uses the mesh structure to maintain a reaction condition of the staining solution.

3. The test kit of claim 1 , wherein, in a process in which the staining solution is transferred to the specimen through the contact surface, the gel receptor inhibits movement of the staining solution by using the mesh structure to prevent residue from remaining at the specimen.

4. The test kit of claim 1 , wherein the contact-type staining patch is a staining patch configured to assign a color to a specific component of the specimen, an antibody patch including an antibody that causes an antigen-antibody reaction with the specimen, or a DNA patch including a DNA probe that couples to a specific DNA sequence of the specimen.

5. The test kit of claim 1 , wherein the staining solution includes the detection inducing substance selected from a staining substance that directly stains the specimen, a precipitation/aggregation inducing substance that either precipitates or aggregates the specimen, a fluorescent sub-stance that allows the specimen to form a fluorescent color, an isotope that allows the specimen to be detected with radiation, and an enzyme attached to the specimen which secretes a detectable substance.

6. The test kit of claim 5 , wherein:

the staining solution includes an attaching substance that is coupled to the detection inducing substance and reacts with a specific component of the specimen to be attached to the specimen; and

the attaching substance includes an antibody that causes an antigen-antibody reaction with the specimen or a DNA probe that has a sequence complementary to a specific DNA sequence of the specimen.

7. The test kit of claim 1 , wherein:

the staining solution is provided in a liquid state; and

the gel receptor is provided as hydrogel that inhibits a leakage of the staining solution in the liquid state to the outside.

8. The test kit of claim 1 , wherein:

the staining solution includes a first staining sample that stains a specimen and a second staining sample that stains the specimen and is different from the first staining sample; and

the part of the staining solution transferred to the specimen includes a part of the first staining sample and a part of the second staining sample.

9. The test kit of claim 1 , wherein the gel reception is provided in a form of a column having a contact surface in which a thickness between the contact surface and a second surface facing away from the contact surface is smaller than a length of the column.

10. A test kit comprising:

a contact-type staining patch comprising:

a staining solution configured to react with a specimen; and

a gel receptor provided as a gel matrix of a mesh structure in which a plurality of pores that contains the staining solution is formed and the mesh structure is configured to prevent the staining solution in the plurality of pores from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer a part of the staining solution to the specimen;

a patch plate storing the contact-type staining patch; and

a specimen plate that is configured to receive the specimen;

wherein relative rotational positioning between the patch plate and the specimen plate causes the specimen, when received by the specimen plate, to react with staining solution.

11. The test kit of claim 10 , wherein:

the staining solution includes a staining sample configured to react with the specimen and a solvent configured to create a reaction condition of the staining sample; and

the gel receptor uses the mesh structure to maintain a reaction condition of the staining solution.

12. The test kit of claim 10 , wherein, in a process in which the staining solution is transferred to the specimen through the contact surface, the gel receptor inhibits movement of the staining solution by using the mesh structure to prevent residue from remaining at the specimen.

13. The test kit of claim 10 , wherein the contact-type staining patch is a staining patch configured to assign a color to a specific component of the specimen, an antibody patch including an antibody that causes an antigen-antibody reaction with the specimen, or a DNA patch including a DNA probe that couples to a specific DNA sequence of the specimen.

14. The test kit of claim 10 , wherein the staining solution includes a detection inducing substance selected from a staining substance that directly stains the specimen, a precipitation/aggregation inducing substance that either precipitates or aggregates the specimen, a fluorescent sub-stance that allows the specimen to form a fluorescent color, an isotope that allows the specimen to be detected with radiation, and an enzyme attached to the specimen which secretes a detectable substance.

15. The test kit of claim 14 , wherein:

the staining solution includes an attaching substance that is coupled to the detection inducing substance and reacts with a specific component of the specimen to be attached to the specimen; and

the attaching substance includes an antibody that causes an antigen-antibody reaction with the specimen or a DNA probe that has a sequence complementary to a specific DNA sequence of the specimen.

16. The test kit of claim 10 , wherein:

the staining solution is provided in a liquid state; and

the gel receptor is provided as hydrogel that inhibits a leakage of the staining solution in the liquid state to the outside.

17. The test kit of claim 10 , wherein:

the staining solution includes a first staining sample that stains a specimen and a second staining sample that stains the specimen and is different from the first staining sample; and

the part of the staining solution transferred to the specimen includes a part of the first staining sample and a part of the second staining sample.

18. The test kit of claim 10 , wherein a gel receptor provided in a form of a column having a contact surface in which a thickness between the contact surface and a second surface facing away from the contact surface is smaller than a length of the column.

19. A test kit comprising:

a contact-type staining patch comprising:

a staining solution having a detection inducing substance configured to react with a specimen; and

a gel receptor provided as a gel matrix of a mesh structure in which a plurality of pores that contains the staining solution is formed and the mesh structure is configured to prevent the staining solution in the plurality of pores from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer the detection inducing substance to the specimen;

a patch plate storing the contact-type staining patch; and

a specimen plate that is configured to receive the specimen;
