Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnosis, in particular to an immunochromatographic test card. Background Technique

[0002] In vitro diagnosis refers to obtaining clinical diagnostic information by detecting samples to be detected in the human body outside the body. Among them, the samples to be detected in the human body include blood, body fluids, tissues, etc.

[0003] In the prior art, a patent document with the authorization announcement number: CN217084997U discloses an immunochromatographic test card containing a diluent, including a bottom shell, a top shell is snap-connected to the bottom shell, a sample adding hole and an observation window are respectively arranged on the top shell, and a limiting member for placing a test strip is arranged on the bottom shell; a dilution unit is arranged on the top shell near the bottom shell side at the sample adding hole; a drying unit is arranged on the top shell near the bottom shell side. By storing the diluent in the dilution unit, the inconvenience, complex operation, and easy contamination during repeated use caused by separately carrying the diluent are avoided.

[0004] However, when the above-mentioned immunochromatographic test card containing a diluent detects a sample to be detected in the human body, the sample to be detected in the human body is poured into the inside of the dilution unit through the sample adding hole, and the sample to be detected in the human body is mixed with the diluent before detection. However, since both the sample to be detected in the human body and the diluent are inside the device, they cannot be stirred and mixed, which will cause the sample to be detected in the human body to be unevenly mixed with the diluent, resulting in inaccurate detection data. Summary of the Utility Model

[0005] Based on the existing problems in in vitro diagnostic technology, the utility model proposes an immunochromatographic test card.

[0006] An immunochromatographic test card proposed by the utility model includes a base, and a top shell is snap-connected and fixed to the upper part of the base. A dilution mechanism is snap-connected and fixed to the bottom of the top shell on the top of the base, and a test paper card is installed at the bottom of the dilution mechanism on the top of the base; an observation window one and a sample adding hole are arranged on the top of the top shell, and a stirring mechanism is movably arranged on the upper part of the top shell on the side of the sample adding hole away from the observation window one; an information code area is fixed on the top of the top shell on the side of the stirring mechanism away from the sample adding hole, and clamping holes one are opened on both sides of the bottom of the top shell.

A rotating shaft is rotatably fixed inside the activity groove. A sealing block is rotatably fixed at the bottom of the rotating shaft. A waterproof pad two adapted to the second notch is fixedly arranged at the bottom of the sealing block. A stirring rod is sleeved on the outer wall of the rotating shaft above the sealing block, and the stirring rod is adapted to the first notch. A rotating handle is fixedly arranged at the top of the rotating shaft. Two clamping holes three are equidistantly opened on the outer side wall of the limiting cylinder at the top of the movable cylinder and on the outer side wall of the upper part of the movable cylinder.
