Description

Technical Field

[0001] The invention belongs to the technical field of blood test shaking and mixing, and specifically refers to a shaking and mixing device for blood test. Background Art

[0002] In the field of medical testing and biological research, the processing of blood samples is a very critical link. Traditional methods of mixing blood samples are often relatively simple, such as simple hand-shaking mixing, which is not only inefficient, but also difficult to ensure the uniformity of mixing. The hand-shaking strength and frequency of different operators vary, which may cause the components in the blood sample to not be fully mixed, affecting the accuracy of subsequent test results.

[0003] Blood has a complex composition and is prone to coagulation and stratification when left at rest. Current common measures to prevent blood coagulation and stratification, such as adding anticoagulants, may interfere with certain test indicators. Moreover, during the period from sample collection to testing, relying solely on anticoagulants is not enough to completely ensure that the blood sample is in an ideal uniform state. Although some existing mixing devices can mix blood samples to a certain extent, the effect of preventing coagulation and stratification is still not ideal because they cannot achieve multi-directional, multi-action mixing and cannot simulate more complex blood flow conditions in the body.

[0004] During the mixing process, some traditional equipment may damage cells and other components in the blood sample due to overly violent movements. For example, excessive mechanical impact may damage the structure of blood cells and affect the reliability of test results. At the same time, there is a lack of a stable fixation design for the blood sample tube, and the sample tube may shake or collide during the mixing process, causing sample leakage or contamination.
