The invention provides a reagent refrigerating device for an analytical instrument and a working method of the reagent refrigerating device, and belongs to the technical field of analytical instrument detection. The reagent refrigerating device for the analytical instrument comprises a refrigerating box, a refrigerating assembly and a uniform mixing assembly, the refrigerating box comprises a shell and a sealing cover, and the sealing cover is rotatably connected with the shell; the shell internally comprises a reagent storage cavity, a cold air circulation channel, a vacuum cavity and a heat preservation shell which are sequentially arranged from inside to outside, the sealing cover internally comprises a liquid nitrogen storage cavity, a refrigeration cavity and a liquid storage cavity which are sequentially arranged in the transverse direction, a mounting cavity is formed in the opposite side of the liquid nitrogen storage cavity, and the liquid nitrogen storage cavity communicates with a discharge pipe; and one end of the discharge pipe is connected with an adjusting valve, and the output end of the adjusting valve is connected with a conveying pipe. A sample reagent bottle is placed in a container, a small motor is powered on to drive a curved block to rotate, a connecting rod drives a supporting column to drive multi-angle shaking with a rotating piece as the axis, and a sample reagent can be evenly mixed.

Description

technical field [0001] The invention belongs to the technical field of biochemical detection, and in particular relates to a reagent refrigeration device for analytical instruments and a working method thereof. Background technique [0002] The reagent refrigeration device is widely used in in vitro diagnostic equipment, such as automatic biochemical analyzer, chemiluminescence immunoassay analyzer, gene sequencer, blood cell analyzer and other in vitro diagnostic equipment. In vitro diagnostic equipment has special requirements for the refrigerated environment of reagents or samples, for example, the refrigerated environment temperature is 2°C-8°C. [0003] In many automated detection instruments, such as chemiluminescence detectors or electrochemical analyzers, it is necessary to use a special reagent refrigeration device to provide functions such as refrigeration, mixing and dispatching of reagents. That is, it is necessary to refrigerate the reagents placed in the reage...
