Description

Technical Field

[0001] The present application relates to the field of medical detection, and in particular to a uniform mixing device. Background Art

[0002] In medical testing practice, the extracted liquid samples (such as blood) are temporarily stored in test tubes, and the liquid samples need to be transported before they can reach the testing room. During the transportation period, the liquid samples will precipitate, causing the composition of the liquid samples at different heights in the test tube to be different. If an unmixed sample is selected for testing, the accuracy and reliability of the test results will be affected.

[0003] In the prior art, liquid samples are mixed by swinging a flat plate or manually shaking. The swinging of the flat plate or manually shaking is highly random, causing the movement of the liquid samples to be disorderly. When mixing multiple liquid samples, the consistency of the mixing of the multiple liquid samples is poor, which is not conducive to evaluating the effect of the mixing of the liquid samples. How to solve the above technical problems is what the technicians in this field need to consider. Utility Model Content
