Description

Technical Field

[0002] Hematology analyzers, also known as blood cell analyzers, hematology meters, and blood cell counters, are one of the most widely used instruments in hospitals for clinical testing. With the rapid development of computer technology in recent years, the technology of blood cell analysis has also shifted from three-category classification to five-category classification, and from two-dimensional space to three-dimensional space. We have also noticed that many of the five-category classification technologies of modern hematology analyzers use the same technologies as today's most advanced flow cytometers, such as scattered light detection technology, sheath flow technology, laser technology, etc.

[0003] Existing blood cell analyzers can only test one sample inside a blood collection tube at a time. If samples inside multiple blood collection tubes need to be tested, the operator must remain near the blood cell analyzer to squeeze out the samples from multiple blood collection tubes, which in turn affects the efficiency of the operator's other work.

A mounting seat 28 is fixedly installed on the end of the connecting rod 27 away from the rotating seat 25. The connecting seat 23 is installed on the lifting seat 22 by bolts. This design makes it easy for the user to disassemble and maintain the stepper motor 26 as a whole. Controlling the operation of the stepper motor 26 can drive the rotating seat 25 to rotate, and then drive the connecting rod 27 and the mounting seat 28 to rotate, thereby realizing the function of replacing the position of the soft blood collection tube 294, thereby driving the uninspected soft blood collection tube 294 to the inspection station.

[0026] In this embodiment, a hard tube 29 is movably connected to the inner wall of the mounting seat 28, a raised block 291 is fixedly connected to the outer wall of the hard tube 29, a rubber block 292 is fixedly connected to the bottom of the raised block 291, the bottom of the rubber block 292 is movably connected to the top of the mounting seat 28, a rubber sealing piece 293 is fixedly connected to the inner wall of the hard tube 29, and a soft blood collection tube 294 is fixedly connected to the top of the hard tube 29.
