AI Technical Summary

Technical Problem

Existing automated blood analyzers suffer from inconsistent operation and low automation in their mixing devices. Manual mixing is time-consuming and labor-intensive, and rotating the mixing device cannot directly aspirate samples, increasing the number of steps required for user operation.

Method used

A mixing device was designed that, through the combination of a sample container carrying component and a limiting component, enables the sample container to switch between vertical and tilted states. Combined with a power component, it automatically completes the mixing and adapts to the sample aspiration requirements.

Benefits of technology

It enables automatic switching between vertical and tilted states of the sample container, improving the mixing effect and the automation of sample aspiration, simplifying the operation process and improving the detection efficiency.

Abstract

A mixing device and a blood analyzer, the mixing device comprising: a sample container bearing part provided with a mounting groove, an opening end of the mounting groove being larger than a bottom end of the groove, the mounting groove being used for bearing a sample container; a limiting part, the sample container being in a vertical state when the limiting part is in a first position, the sample container being in an inclined state when the limiting part is in a second position; and a first power part, the first power part being used for driving the sample container bearing part to rotate. Since the sample container can be in the vertical state and the inclined state in the mounting groove, the sample container can be mixed in the inclined state, a good mixing effect is realized, the sample container can be in the vertical state, which is beneficial to sample suction, the sample container can be directly switched between the two states on the sample container bearing part, the user does not need to put the sample container right after the sample container is mixed in the inclined state, manual operation is simplified, the automation of mixing and sample suction is improved, and finally the detection efficiency is improved.
