Description

Technical Field

[0001] The utility model relates to the technical field of reagent cartridges, in particular to a reagent cartridge for detecting whole blood. Background Art

[0002] The reagent cartridge is a plastic card used in the immunochromatography reagent process. The card is loaded with test pieces consisting of NC membrane, absorbent paper, conjugate pad, buffer pad, and blood filter membrane. The reagent cartridge carries these components to form a reagent test card.

[0003] According to a whole blood reagent cartridge disclosed in Chinese patent CN202122043025.8, the application sets a first pit, a second pit, and a second raised strip through an upper cover, a rectangular sample loading hole is set at the bottom of the first pit, the back side of the sample loading hole corresponds to the position of the blood filter membrane of the reagent card, the second pit corresponds to the position of the nitrocellulose membrane, the second raised strip is located on the back side of the upper cover, the second raised strip is set perpendicular to the direction of the guide groove, and the second raised strip corresponds to the position between the binding pad and the nitrocellulose membrane; a guide groove is set along the direction of the sample loading hole on the back side of the upper cover, the guide groove covers the position of the sample loading hole, and can guide the sample to the position of the nitrocellulose membrane of the reagent card; the lower shell cooperates with the upper cover to form a box body structure. The contact area between the sample and the blood filter membrane is increased, and at the same time, the flow of the sample is guided, avoiding or reducing the phenomenon of red blood cell damage in the whole blood sample. The number of red blood cells remaining on the blood filter membrane is increased, and the accuracy of the test results is improved. The existing reagent card housing has poor installation reliability between the bottom shell and the upper cover, and the upper cover is easy to fall off from the bottom shell, and the sample addition hole lacks a protective structure. Dust can easily enter the sample addition hole in advance before the card is used, contaminating the reagent card, thereby affecting the detection accuracy.
