Technical Field

[0001] The utility model relates to the field of blood detection and analysis, in particular to a blood centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. A centrifuge is mainly used to separate solid particles from liquids in a suspension, or to separate two immiscible liquids of different densities in an emulsion. It can also be used to remove liquid from wet solids. During the detection and analysis of blood, a centrifuge can be used to process the blood.

[0003] However, the current blood centrifuges still have some shortcomings. For example, a blood centrifuge with application number 202320020113.2 has not yet fully considered the test tube picking structure of the blood centrifuge. During the use of the blood centrifuge for blood testing and analysis, if the blood centrifuge does not fully consider the test tube picking structure, the staff may drop the test tube when picking up the test tube, resulting in test tube breakage, and the centrifugation results of the blood in the test tube may be affected to a certain extent, thereby affecting the accuracy of subsequent blood test results, and it is inconvenient for the staff to use the blood centrifuge.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structure and shortcomings, and provides a blood centrifuge. Utility Model Content
