Method and device of reaction cup movement path control

Abstract

The invention provides a method and device of reaction cup movement path control, wherein the method comprises the following steps: in response to a demand of adding a reaction cup, the reaction cup pusher is controlled by a controller to move to a second ultimate limit state, so that a blocking part of a cup body of the reaction cup pusher is relieved from blocking a first reaction cup positionedat a waiting station, the first reaction cup positioned at the waiting station enters a cup body guiding channel of the reaction cup pusher, the controller controls the reaction cup pusher to move toa first ultimate limit state, the cup guiding channel is communicated with the next station, so that the first reaction cup entering the guiding channel of the cup body is conveyed to the next station, the reaction cup next to the first reaction cup arranged in a conveying trough of the reaction cup into the waiting station, and the reaction cup entering the waiting position is blocked at the waiting station by the blocking part of the cup. By the method, only one reaction cup can be transported from the waiting station to the next station at one time, and the control flow of the component atthe next station can be simplified.

Description

technical field [0001] The invention relates to the field of in vitro diagnosis, in particular to a method and device for controlling the motion path of a cuvette. Background technique [0002] In the in vitro diagnostic analyzer, the cuvettes are transported from the cuvette silo to the loading channel through the conveyor chain, lined up in the loading channel and sequentially pass through the loading device to enter the next designated position, such as a reagent tray. A through hole corresponding to the outlet of the loading channel is provided on the traditional loading device, and a switch assembly is provided on the through hole to open and close the through hole. When the cuvette needs to be loaded, the through hole is opened and closed by the switch assembly, so that The first cuvette at the position falls into the through hole. In the cuvette loading device with this structure, in the process of loading cuvettes, it is easy for the cuvette behind the first cuvette...

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
