[0002] Blood cell analyzer, also known as blood cell analyzer, blood cell meter, blood cell counter, etc., is one of the most widely used instruments in hospital clinical testing. With the rapid development of computer technology in recent years, the technology of blood cell analysis has also shifted from three groups to five groups, and from two-dimensional space to three-dimensional space. We have also noticed that many of the five-category technologies of modern blood cell analyzers use the same technology as today's very advanced flow cytometers, such as scattered light detection technology, sheath flow technology, laser technology, etc.

[0003] At present, for some blood samples, before using a blood cell analyzer for analysis, staff are required to manually mix the sample tubes in advance to make the red blood cells completely suspended. However, manual shaking may cause uneven mixing, which may affect the test results of the samples. Existing blood analyzers do not have the function of mixing sample tubes. Utility Model Content

[0026] In some embodiments, the inner wall of the placement groove 4 is symmetrically provided with accommodating cavities 7, and one end of each of the accommodating cavities 7 is respectively connected to the placement groove 4; a sliding plate 8 is slidably connected in the accommodating cavity 7, and the sliding plate 8 is rotatably connected to a first elastic roller 9 at one end close to the inner wall of the placement groove 4, and the first elastic roller 9 is arranged outside the accommodating cavity 7; a compression spring 10 is provided between the end of the sliding plate 8 away from the inner wall of the placement groove 4 and the accommodating cavity 7.

[0027] In some embodiments, the inner bottom wall of the placement groove 4 is rotatably connected to a second elastic roller 11 , and the second elastic roller 11 is driven to rotate by a second motor; the second motor is electrically connected to the analyzer body 1 .

[0028] In some embodiments, the inner side wall of the placement groove 4 is further symmetrically provided with auxiliary rollers 12 , and the auxiliary rollers 12 are rotatably connected to the inner side wall of the placement groove 4 ; the auxiliary rollers 12 are arranged below the first elastic rollers 9 .

[0030] Specific usage:

[0031] First, take out the sample tube to be analyzed from the refrigerator, place it on the sample placement rack 14 for 15 minutes to allow the sample tube to return to room temperature, then take out the sample tube and press it to place it in the placement groove 4.

[0032] During the placement process, the sample tube 2 spreads the first elastic rollers 9 on both sides of the placement groove 4, and the first elastic rollers 9 roll along the outer surface of the sample tube 2.
