As shown in fig. 6, the outer surface of the second cup 2 is provided with a protruding block 22. The surface of the protruding block 22 is a plane, so that an identification label can be conveniently stuck, and meanwhile, the protruding block can be matched with an instrument, so that the direction of the reagent cup can be automatically identified when the reagent cup is installed on the instrument, and the incorrect matching direction of the reagent cup and the instrument is avoided.

In the production process, all the accessories can be prepared completely, and then the packaging of the reagent and the assembly of the accessories are carried out. Specifically, as shown in fig. 4, the piston puncturing element 6 is inserted into the first sealing cavity 3 of the upper cup 8, so that the limiting rib 18 on the piston part 15 is clamped into the limiting groove 17 in the first sealing cavity 3, and since the piston part 15 is made of a silica gel material, the piston part is inserted into the first sealing cavity 3 and then is tightly attached to the cavity wall of the first sealing cavity 3, so that one end of the first sealing cavity 3 is sealed by the piston part 15, the upper cup 8 is inverted, then the first sealing cavity 3 is filled with a first reagent, the puncturing part 16 is located in the soaking of the first reagent, a sealing film is sealed at the sealing position of the first sealing cavity 3, and the first reagent is sealed in the first sealing cavity 3. As shown in fig. 3, the lower cup 9 is assembled with the upper cup 8, and specifically, the connection ring 11 of the lower cup 9 is inserted into the mounting groove 10 of the upper cup 8 while the annular rib 13 is snapped into the annular groove 12. As shown in FIG. 6, the second reagent is poured into the second sealed cavity 4 of the second cup body 2, and then the sealing film is sealed at the sealing port of the second sealed cavity 4, so that the second reagent is preserved in the second cup body 2. Thus, after the reagents have been packaged, the first cup 1 with the first reagent, the second cup 2 with the second reagent and the ejection lever 7 are stored separately, e.g. in different locations in a single package.

In the using process, the sample, the first reagent and the second reagent need to be uniformly mixed according to steps, the sample and the reagents are subjected to chemical reaction to form a reaction solution, and then the optical characteristics of the reaction solution can be detected by an instrument. Therefore, some preparation work is required before the detection is performed. Specifically, a certain amount of sample, such as blood, is drawn by the sampling needle 5 on the first cup body 1, and the sample can be drawn inside the blood taking needle by capillary action since the blood taking needle is a glass tube having a capillary lumen. After the sample is sucked, the first cup body 1 needs to be installed on the second cup body 2, firstly, the sealing film on the second cup body 2 is torn off, then the blood sampling needle is inserted into the second sealing cavity 4 of the second cup body 2, the assembling groove 20 on the first cup body 1 is clamped with the assembling rib 21 on the second cup body 2, and then the two cup bodies are connected into a whole. In the assembly process, because the air pressure in the second sealed cavity 4 is unbalanced with the outside, especially when the lower end part of the first cup body 1 is overlapped with the upper end part of the second cup body 2, the communication of the air inside and outside is cut off, the first cup body 1 is difficult to continue to enter the second cup body 2, thus, an accommodating groove 19 is arranged at a proper position on the first cup body 1, partial air can be accommodated, the accommodating groove 19 is positioned at a specific position on the first cup body 1, when the first cup body 1 is just contacted with the second cup body 2 in the assembly process, the accommodating groove 19 is positioned at the position just contacted, and meanwhile, the length of the accommodating groove extends up and down for a part, as shown in fig. 2. After first cup 1 and the assembly of second cup 2 are accomplished, just constituted complete reagent cup, the blood taking needle that has the sample this moment is located second seal chamber 4, rocks the reagent cup, makes and store in the sample of capillary inner chamber in the blood taking needle fall to second seal chamber 4 in, continues to rock the reagent cup, makes sample and the second reagent misce bene in the second seal chamber 4. After the sample and the second reagent are mixed uniformly, the push-out rod 7 is inserted into the back of the piston part 15 from the upper end of the first body, and the piston part 15 is pushed downwards, so that the puncture part 16 pierces the sealing film at the lower end of the first cup body 1 when moving downwards, and simultaneously, the piston part 15 can extrude all the first reagent in the first sealing cavity 3, so that the first reagent falls into the second sealing cavity 4 of the second cup body 2, and the sample, the first reagent and the second reagent are mixed together, and a chemical reaction can be carried out to generate an optical characteristic. Before the chemical reaction is finished, the reagent cup is put into the detection instrument in its entirety, and the reagent cup can be put into the detection station of the instrument according to the exact direction specified by the instrument by the convex block 22 on the reagent cup, so that the detection process can be completed.
