[Background technology]

[0002] In general, with the development of medicine and various related technologies, tests are being conducted for substances such as blood cells, nucleic acids, proteins, and antigens contained in a specific biological sample such as blood. After collecting such a sample, the collected sample is reacted with a specific reagent, and the changes that occur after the reaction are analyzed and observed, thereby testing the presence or absence, ratio, and amount of various substances contained in the sample, and thereby obtaining information on the presence or absence of a disease, the state of the disease, and the like.

[0003] In the process of testing such samples, it is very important to obtain reproducible and accurate results that the samples and reagents used in testing the samples are not affected by external factors and that accurate amounts are used each time. Since the samples and reagents may be exposed to the outside during the testing process, it is necessary to effectively prevent contamination due to such exposure of the samples and reagents and to use accurate amounts to ensure the accuracy of the testing.

[0004] It is also necessary to enable tests for detecting and reading / analyzing the reaction results after the reaction between the reagent and the sample to be performed accurately and quickly under one integrated system, thereby reducing test time and costs, and reducing the steps involved in the entire test and the costs involved.

[0101] The container lid 220 is detachably coupled to the upper part of the container body 210. The container lid 220 is provided with a plurality of lid vent holes 221. The lid vent holes 221 allow air to flow into the solution containing portion 211.

[0102] That is, the solution storage section 211 is at atmospheric pressure due to the lid vent 211. This allows the dissolving solution to flow in the direction of gravity when punching holes in the punching layer, even without a separate driving device.

[0103] Further, a plurality of hooks 355 are provided in the container insertion space 353 so as to protrude into the container insertion space 353. The hooks 355 are inserted into the vial container 200 to prevent the vial container 200 from coming out of the container insertion space 353.

[0104] The cartridge code 375 is a portion in which the code name of the test cartridge 300 in which the test reagent 10 is carried is written.

[0105] The multiple fitting protrusions 351 are protrusions that protrude vertically from the lower portion of the container mounting part 350. The multiple fitting protrusions 351 are fitted into the side fitting grooves 319b of the reagent reaction part 310. In this way, the container mounting part 350 is coupled to the reagent reaction part 310. The container mounting part 350 and the reagent reaction part 310 are coupled so as to be stacked vertically.

[0106] When the vial container 200 is inserted into the container insertion space 353, the hooks 355 of the container mounting part 350 are engaged with the mounting grooves to support the side of the vial container 200. The container mounting part 350 stably holds the vial container 200 so that the dissolving liquid in the vial container 200 flows in the direction of gravity.

[0107] The above-described preferred embodiments of the present invention have been disclosed for illustrative purposes, and those skilled in the art having ordinary skill in the art may make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the following claims. [Industrial Applicability]

[0108] The present invention can distribute and guide the dissolving solution stored in a vial container evenly to each chamber when the dissolving solution flows into each chamber containing a test reagent.
