The outward movement of the piston 33 generates negative pressure inside the second sleeve 32. The negative pressure generated inside the second sleeve 32 will draw the blood inside the cylinder 19 into the second sleeve 32 through the second connecting tube 34 and the first circular hole 111. At this time, the piston 33 continues to move outward. When the piston 33 continues to move outward to the other end of the second sleeve 32, the blood inside the second sleeve 32 is Blood will flow out from the third connecting tube 35, and the second connecting tube 34 will be blocked when the piston 33 moves into the second sleeve 32. The tube mouth diameter of the second connecting tube 34 is small, and blood will not actively flow out from the second connecting tube 34. The tube mouth diameter of the second connecting tube 35 is larger than the tube mouth diameter of the second connecting tube 34, so blood can flow out directly from the second connecting tube 35. The second sleeve 32 can be set up to draw the blood inside the cylinder 19 into the test tube 45 when the first motor 12 stops rotating.

[0045] The blood flowing out of the third connecting tube 35 passes through the second circular hole 48 in the center of the first rubber disk 36 and the second rubber disk 47 and enters the inside of the test tube 45. The test tube 45 is made of glass and has scales on the side wall so that the internal situation and scales can be observed from the outside. At this time, the second motor 41 is started to rotate, and the rotation of the second motor 41 drives the rotating rod 42 to rotate, and the rotation of the rotating rod 42 drives the disc 43 to rotate, and the rotation of the disc 43 drives the first fixed block 44 to rotate, and the rotation of the first fixed block 44 drives the test tube 45 to rotate around the rotating rod 42. The test tube 45 rotates around the rotating rod 42 to centrifuge the blood in the test tube. The centrifugation of the blood will stratify the different components in the blood, and the centrifugation will cause the blood cells to settle to the bottom of the test tube 45. The rotation of the second motor 41 drives the test tube 45 to be centrifuged to stratify the blood components inside it.

[0046] After centrifugation is completed, the sliding tube 51 is pulled downward to move downward, and the sliding tube 51 moves downward to drive the second fixed block 52 to move downward, and the second fixed block 52 moves downward to drive the second hollow groove 53 to move downward, and the second fixed block 52 is pulled down to the place where the plasma and blood cells are layered. At this time, the plasma at the upper end will flow out from the second hollow groove 53, and after all the plasma in the test tube 45 flows out, the third sliding block 54 is pulled outward at the groove 55, and the third sliding block 54 is away from the first hollow groove 46. At this time, the blood cells in the test tube 45 will be discharged from the first hollow groove 46.
