Description

Technical Field

[0001] This utility model relates to the field of reagent storage, and in particular to a reagent storage for a fully automated chemiluminescence immunoassay analyzer. Background Technology

[0002] A default requirement for high-throughput fully automated chemiluminescence immunoassay analyzers is that a single instrument can test more items, carrying reagents for more than 30 tests. A typical Roche 801 instrument can carry 47 items. This places two demands on the reagent compartment of high-throughput instruments: efficient reagent needle aspiration and a larger reagent capacity.

[0003] In addition to providing a refrigerated environment for the reagents, the existing rotary reagent compartment also positions the corresponding reagents to the sampling port of the reagent needle by rotation, assisting the reagent needle in aspirating the reagents. Essentially, it breaks down the sampling action of the reagent needle into the action of two parts, thereby improving the efficiency of the instrument.

[0004] To meet the requirement for larger reagent capacity, a natural extension of the approach is to increase the size of the disc-shaped reagent compartment. However, this presents two problems: First, the inertia of the disc increases exponentially with its diameter, placing more stringent demands on its high-speed control, making it unable to meet the auxiliary sample dispensing function of high-throughput, high-speed instruments. Second, a single-ring arrangement of reagents leads to wasted space in the central area of ​​the disc. Of course, reagents can be arranged in two or more rings, but this still cannot solve the problem of excessive overall inertia that prevents the high-speed auxiliary sample dispensing function from being met.

[0005] In addition, with the increase in reagent capacity, the existing manual loading and unloading of reagents and empty reagent kits has two problems: on the one hand, it is labor-intensive; on the other hand, the reagent compartment interface must be easy for personnel to operate, otherwise it is inconvenient to load reagents and unload empty reagent kits, which limits the layout design of the instrument.

[0006] Therefore, it is necessary to propose a reagent compartment for a fully automated chemiluminescence immunoassay analyzer to solve the above problems. Utility Model Content

[0007] The main objective of this invention is to provide a reagent compartment for a fully automated chemiluminescence immunoassay analyzer, which can effectively solve the problems in the background art.

[0013] Preferably, an inner ring drive assembly is installed on the other side of the bottom of the base cavity.
