Abstract

The invention provides a reagent card. The reagent card comprises a main body part; the sample area is communicated with a container for accommodating a sample to be detected; the first reagent area is internally provided with a first reagent mixed with a sample to be detected, the first reagent area is provided with a first liquid inlet and a first liquid outlet, and the first liquid inlet is communicated with the sample area through a first liquid channel; a stirring device is arranged in the second reagent area, the second reagent area is communicated with the first liquid outlet of the first reagent area through a second liquid channel, and a first stop valve is arranged on the second liquid channel; the first end of the first gas channel is communicated with the first reagent area, and the second end of the first gas channel is a first negative pressure end; the first end of the second gas channel is communicated with the second reagent area, and the second end of the first gas channel is a second negative pressure end. By applying the technical scheme provided by the invention, the problem of poor mixing effect of the reagent and the liquid sample in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the field of liquid detection, in particular to a reagent card. Background technique [0002] Microfluidic detection is currently a development direction for in vitro diagnosis, food safety, and pesticide residue detection. Reagent cards are commonly used products in the field of microfluidic detection. Because of their small size and small sampling volume, they have been widely used in the field of microfluidic detection. At present, in the application process of the reagent card, it is often necessary to mix the collected liquid sample with the reagent, and then test the properties of the mixed liquid sample. [0003] The reagent card in the related art is generally provided with a reagent area, where reagents that need to be mixed with liquid samples are placed, wherein the reagents can be in various states such as powder, solid particles, freeze-dried beads, and liquid. Liquid samples need to be fully mixed with reagents ...
