[0002] When using a biochemical reagent testing device to detect some biochemical reagents, it is necessary to use a special identification reagent to react with the biochemical reagent before the biochemical reagent can be detected and processed.
[0003] After searching, the utility model patent with Chinese patent number CN202221918716.6 discloses a biochemical reagent rapid detection device, including a body, a first drug feed component, a second drug feed component, a pulling component and a driving mechanism. A detection cylinder is installed on the top of the body, the first U-shaped frame is installed on the top of the first support rod, the first drug feed cartridge is movably connected to the inside of the first U-shaped frame through a first torsion spring shaft, the second U-shaped frame is installed on the top of the second support rod, and the second drug feed cartridge is movably connected to the inside of the second U-shaped frame through a second torsion spring shaft. Two groups of pulling components are respectively installed on the two side edges of the top of the body, and the driving mechanism is installed on the side wall of the detection cylinder. The driving mechanism works and cooperates with the two groups of pulling components to make the first drug feed cartridge and the second drug feed cartridge staggered and shake up and down, so that the biochemical reagents and identification reagents are poured into the detection cylinder intermittently in turn, so that the two groups of reagents are mixed with each other in turn during the injection process, so that the two can be quickly mixed and reacted thoroughly.
[0004] Although the biochemical reagents and identification reagents are intermittently poured into the interior of the detection cylinder when the first medicine inlet cylinder and the second medicine inlet cylinder are shaken up and down, some biochemical reagents and identification reagents are still separated, and the mixing effect is still relatively poor.

In addition, when discharging the reagents in the detection cylinder, the body and the detection cylinder need to be turned over for discharge. When the detection cylinder is turned over and the cover on the detection cylinder is taken off, the biochemical reagents may flow onto the hands of the staff. At the same time, it is not convenient to clean the inside of the detection cylinder.
