Reaction cup push block and reaction cup loading device

Abstract

The present invention provides a cuvette pusher block and a cuvette loading device. The cuvette pusher block includes a cup body blocking portion for blocking the cuvette at the waiting station, and a cuvette block for guiding the single cuvette at the waiting station to the The cup body guiding part, the cup body blocking part and the cup body guiding part of the next station can be respectively docked with the waiting station through the movement of the push block body. Since a cup body guiding part that can accommodate a single cuvette and a cup body blocking part that can block the cuvette are provided, by moving the cuvette push block, the cup body guiding part or the cup body blocking part is respectively docked with the waiting station, In this way, the purpose of transporting the cuvette is achieved, and the cuvette passes through a certain transport path during the process of guiding the cuvette to the next station, so that the final outlet of the cuvette is staggered from the inlet of the cuvette at the waiting station, which can simplify the process. Control flow.

Description

technical field [0001] The invention relates to the field of in vitro diagnosis, in particular to a cuvette pushing block and a cuvette loading device. Background technique [0002] In the in vitro diagnostic analyzer, the cuvette is transported from the cuvette silo to the loading channel through the conveyor chain, queued in the loading channel, and then passes through the loading device to the next designated position, such as the reagent tray. The traditional loading device is provided with a through hole corresponding to the outlet of the loading channel, and a switch assembly that functions to open and close the through hole is arranged on the through hole. The first cuvette at the drop into the through hole. In the process of loading the cuvette with this structure, the cuvette behind the first cuvette is prone to fall into the through hole before the switch assembly can be closed, so that multiple reaction cuvette The cups are stacked between the next station below...

AI Technical Summary

Problems solved by technology

In the cuvette loading device with this structure, in the process of loading cuvettes, it is easy for the cuvette behind the first cuvette to fall into the through hole before the switch assembly is closed, so that multiple reactions The cups are piled up between the next station under the through hole and the position of the through hole, which prevents the switch assembly from closing, resulting in tube jamming
