Description

TECHNICAL FIELD

[0002] In the blood detection process, centrifugal processing is a key step for separating serum, plasma, blood cells and other components in blood, which relies on a blood detection centrifugal device to realize component layering under high-speed rotation. Currently, a conventional blood centrifugal device usually adopts a fixed rotor structure, and a plurality of hole positions for placing blood test tubes are arranged on the rotor. When in use, the test tubes need to be inserted into the hole positions one by one and manually fixed, and then taken out one by one after centrifugation to realize blood centrifugation.

[0003] However, such back-and-forth taking and placing of single blood test tubes is complicated and inefficient, especially in a batch detection scenario, frequent taking and placing of single test tubes not only increases the working strength of the operator, but also may affect the detection timeliness due to long operation time.

[0004] Meanwhile, the test tube fixing structure of the existing centrifugal device is relatively single, and usually only fixed by interference fit between the inner wall of the hole position and the test tube, which is difficult to adapt to blood test tubes of different specifications (diameter, length), and may easily cause problems such as test tube shaking and tilting, which not only affects the centrifugal separation effect, but also may cause test tube rupture due to violent vibration in the centrifugal process, resulting in blood sample leakage and the risk of cross contamination.

[0005] In addition, most centrifugal devices lack effective protection structures, and if the test tubes overflow during high-speed rotation, cross infection may be caused, and if they are loose, the sample may splash, threatening the safety of the operator; and the rotor and the test tube placing assembly of the existing device are usually designed in an integrated manner, so when a test tube hole position is worn or fails, the rotor needs to be replaced as a whole, which is high in maintenance cost.

[0006] Therefore, in view of the deficiencies of the existing blood detection centrifugal device in operation efficiency, adaptability, safety and maintenance convenience, it is urgent to design a blood detection centrifugal device which can realize batch taking and placing of test tubes, adapt to test tubes of various specifications, has a stable protection structure and is convenient to maintain.
