Full-automatic biochemical analyzer and stirring device thereof

Abstract

The invention provides a full-automatic biochemical analyzer and a stirring device thereof. The stirring device has a good stirring effect and relatively high stirring efficiency. The stirring device provided by the invention comprises a stirring paddle and a stirring motor. The stirring motor is connected with a swing member swinging reciprocatingly with the rotation of the stirring motor. The stirring paddle is provided with a drive member for driving the rotation of the stirring paddle. The swing member is connected to the drive member. The reciprocating swing of the swing member drives the drive member to make forward and backward bi-directional rotation. In the stirring device provided by the invention, the stirring motor is connected to the drive member of the stirring paddle through the swing member, so that the stirring motor can drive the swing member to swing reciprocatingly without changing the rotation direction of the stirring motor, so as to change the rotation direction of the drive member, realize bi-directional driving of the drive member and further drive the stirring paddle to bi-directionally rotate and stir, thereby increasing stirring efficiency and achieving a better stirring effect.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a stirring device for a fully automatic biochemical analyzer. The present invention also relates to a full-automatic biochemical analyzer provided with the stirring device. Background technique [0002] The automatic biochemical analyzer is an important analytical instrument used in clinical testing, in order to measure various biochemical indicators through the analysis of blood or other body fluids, so as to provide scientific data basis for doctor's diagnosis. [0003] Existing full-automatic biochemical analyzers include a stirring device. The function of the stirring device is to fully mix the sample and the reagent in the cuvette, and whether the sample and the reagent are fully mixed will largely affect the accuracy of the test result. Therefore, the stirring device is an important part of the automatic biochemical analyzer. [0004] At present, the stirring de...

AI Technical Summary

Problems solved by technology

[0005] In the above-mentioned existing stirring devices, it is not easy to achieve sufficient mixing of samples and reagents in the stirring mode of plane blades and single direction of rotation, and its stirring effect is poor, which affects the accuracy of test results; Mixing, the required stirring time is relatively long, and the stirring efficiency is low, which makes the detection time longer

It can be seen that the existing stirring device cannot meet the requirements of a higher-speed automatic biochemical analyzer
