Problems solved by technology

[0007] However, in Patent Document 1, when the tray 500 is taken out from the refrigerator and transported for use in inspections, the reagent in the reaction tank 504 may flow back into the reagent storage box 502 through the thin tube 503
If the test is performed with the reagent flowing back into the reagent storage tank 502 and remaining in the reagent storage tank 502, the quantitative performance of the reagent in the reaction tank 504 will decrease.

Embodiment approach 2

[0165] Such as Figure 13 As shown in (a), in the liquid supply part 127 of Embodiment 2, compared with Embodiment 1, the second sealing part 212, the air port 224, the recessed part 231, and the connection flow path 232 are omitted. In addition, the Y-axis positive end of the liquid storage part 210 is connected to the air introduction path 233 , and the other end 222 of the bypass flow path 220 is connected to the air introduction path 233 . Other structures are the same as those in Embodiment 1.

[0166] In the second embodiment, the liquid injected from the injection port 223 enters the liquid storage part 210 from the one end 221 as in the first embodiment. At this time, the hole 234 is connected to the inside of the liquid storage part 210 . The hole 234 is opened before the liquid is injected, and the air in the liquid storage part 210 is exhausted from the hole 234 . When the injection of the liquid is completed, the injection port 223 and the hole 234 are blocked b...

Embodiment approach 5

[0176] Such as Figure 14 As shown in (b), in the liquid supply unit 127 of the fifth embodiment, compared with the fourth embodiment, one end 221 of the bypass channel 220 is connected to the channel 244 . Other structures are the same as those in Embodiment 4.

[0177] In Embodiment 5, when the liquid is injected, the liquid that has flowed into the flow path 244 from the one end 221 advances toward the liquid storage portion 210 through the flow path 244 . Therefore, in the fifth embodiment, the injection of the liquid can also be performed in the same manner as in the first embodiment. In addition, when the liquid is transferred, the first sealing portion 245 and the second sealing portion 212 are unsealed, so that the liquid can be transferred in the same manner as in the first embodiment.

Embodiment approach 6

[0179] In Embodiment 6, such as Figure 15 As shown, compared with Embodiment 1, the supporting member 410 is arranged instead of the supporting member 313 , and the liquid sealing case 420 is used instead of the liquid sealing case 100 . About other structures, it is the same as that of Embodiment 1.

[0180] The supporting member 410 has a hole 411 and three setting portions 412 . A hole 411 is provided at the center of the support member 410 . The supporting member 410 is provided on the rotating shaft 310 . Thereby, the support member 410 is rotatable around the rotation shaft 310 . Three setting parts 412 are provided in the rotation direction. The installation part 412 has a surface 412a and a hole 412b. The surface 412a is one level lower than the upper surface of the supporting member 410 . The hole 412b is formed in the center of the surface 412a, and penetrates the support member 410 in the vertical direction. The liquid sealing case 420 has a rectangular shap...

Abstract

The present invention provides a liquid enclosing case, a method of manufacturing the liquid enclosing case, and a liquid transfer method, which can appropriately transfer a predetermined amount of liquid during use. The liquid injected from the injection port (223) is sealed in advance in the liquid sealing case (100), and the liquid is transferred by the centrifugal force applied by rotating. The liquid sealing box (100) has: a liquid storage part (210) for storing liquid; one end (221) and the other end (222) are connected to the liquid storage part (210) and have a bypass flow path ( 220); and a transfer channel (243) for transferring liquid from the liquid storage part (210) when a centrifugal force is applied.

Description

technical field [0001] The present invention relates to a liquid enclosing case, a method of manufacturing the liquid enclosing case, and a liquid transfer method. Background technique [0002] Such as Figure 16 As shown, Patent Document 1 discloses that a certain amount of reagent is injected into the reagent storage box 502 from the input port 501 before the test, and then the disk 500 is rotated at a high speed, so that the reagent in the reagent storage box 502 is transported through the fine tube by centrifugal force. The tube 503 is transferred to the reaction tank 504 . [0003] In addition, Patent Document 1 discloses that after the reagent is transferred from the reagent storage box 502 to the reaction tank 504, the tray 500 is placed in a refrigerator to gel the reagent transferred to the reaction tank 504. custody. [0004] prior art literature [0005] Patent Document 1: Specification of US Patent Application Publication No. 2011 / 0104009 [0006] In Patent D...
