Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oscillating device for blood samples. Background Art

[0002] In blood collection and supply institutions and medical testing fields, the analysis of blood samples is an important means to determine whether blood is qualified, diagnose diseases, assess health status and conduct medical research. In order to ensure the accuracy and reliability of blood samples during the testing process, uniform mixing of samples and prevention of coagulation are crucial. Traditional blood sample processing methods often rely on manual shaking or simple mechanical dithering. Manual shaking is inefficient and the oscillation is uneven. The amplitude and frequency of each oscillation cannot be kept consistent, which cannot meet the high-efficiency needs of modern medical testing. Although simple mechanical shaking can reduce manual labor, its oscillation method is often single, for example, it can only oscillate in a single direction and cannot adapt to blood samples of different types and properties. Therefore, it is necessary to purchase multiple additional shaking equipment, resulting in increased usage costs. Utility Model Content
