Abstract

Claims (30)

1 . A diagnostic device using a test kit, the diagnostic device comprising:

a body having a loading region in which a test kit is placed, the test kit comprising a specimen plate having a specimen region and a patch plate that stores a contact-type staining patch, the patch plate being coupled with the specimen plate in a structure allowing relative sliding movement between the two plates;

a moving unit configured to transmit power to a first mounting portion on which the patch plate of the test kit is mounted or a second mounting portion on which the specimen plate is mounted such that the patch plate and the specimen plate move relative to each other so that the specimen placed in the test kit is smeared in the specimen region; and

a contact unit hitting a structure of the test kit to bring the contact-type staining patch within the patch plate into contact with the smeared specimen to stain the smeared specimen.

2 . The diagnostic device of claim 1 , further comprising an image acquisition module configured to acquire an image of the stained specimen.

3 . The diagnostic device of claim 2 , further comprising a diagnostic module configured to diagnose a state of the specimen on the basis of the acquired image of the stained specimen.

4 . The diagnostic device of claim 2 , wherein the image of the stained specimen is generated after one or more of the test kit having the stained specimen placed therein and the structure of the test kit are moved.

5 . The diagnostic device of claim 2 , wherein the image of the stained specimen is generated by combination of a plurality of frame images of the stained specimen.

6 . The diagnostic device of claim 1 , wherein:

the relative movement of the diagnostic device has a form such that the patch plate is moved in one direction and the specimen plate is fixed or moved; and

when the specimen plate is moved in the one direction, a movement speed of the patch plate is higher than a movement speed of the specimen plate.

7 . The diagnostic device of claim 1 , wherein:

the loading region is formed inside the body; and

the diagnostic device further comprises a loading region moving unit configured to move the loading region,

wherein the loading region moving unit moves the loading region to allow a user to place the test kit in the loading region.

8 . The diagnostic device of claim 1 , wherein the moving unit includes a power generator configured to generate power and a power transmission member configured to transmit the power to the structure of the test kit.

9 . The diagnostic device of claim 8 , wherein:

the power generator and the power transmission member are engaged with each other; and

the moving unit transmits the power to the specimen plate and the patch plate through the power transmission member.

10 . The diagnostic device of claim 1 , wherein the contact unit comprises a power generator configured to generate power and a power transmission member configured to transmit the power to the structure of the test kit.

11 . The diagnostic device of claim 10 , wherein:

the power generator and the power transmission member are engaged with each other; and

the contact unit transmits the power to the contact-type staining patch stored in the patch plate through the power transmission member.

12 . The diagnostic device of claim 1 , wherein the moving unit:

does not allow the relative movement of the test kit when the contact-type staining patch is in contact with the specimen region; and

allows the relative movement of the test kit when the contact-type staining patch is not in contact with the specimen region.

13 . A diagnostic method using a test kit, the diagnostic method comprising:

loading a test kit having a specimen placed therein to the diagnostic device of claim 1 , wherein the test kit comprises a specimen plate having a specimen region in which a specimen is smeared and a patch plate that stores a contact-type staining patch, the patch plate being coupled with the specimen plate in a structure allowing relative sliding movement between the two plates;

transmitting power to a structure of the test kit for the patch plate and the specimen plate to move relative to each other so that the specimen placed in the loaded test kit is smeared; and

transmitting power to hit an upper surface of the patch plate of the test kit such that the contact-type staining patch within the patch plate moves and comes into contact with the smeared specimen so that the smeared specimen is stained.
