Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a blood centrifugation device. Background Art

[0002] In hospitals, it is most common to collect blood through vacuum blood collection tubes. Blood collection nurses will use a blood collection device with a double-headed needle. One end is inserted into the patient's vein, and the other end is inserted into the vacuum blood collection tube. The negative pressure inside the vacuum blood collection tube will automatically suck the blood into the tube. When it is necessary to separate the components or detect the quality of stored blood, the blood will be transferred from the blood bag into a centrifuge tube.

[0003] When collecting blood or transferring it into a centrifuge tube, it is not convenient to balance the blood inside the centrifuge tube, resulting in different weights of the centrifuge tubes. When the centrifuge rotates at high speed, the imbalance caused by the weight problem will cause the centrifugal force to continuously change direction with the rotation, causing the overall vibration of the centrifuge, thereby shortening the service life of the centrifuge. Moreover, when placing centrifuge tubes inside the centrifuge, due to the uncontrollable number of centrifuge tubes, it is easy to cause uneven distribution of the centrifuge tubes. The uneven vibration may cause cell components with different sedimentation coefficients not to settle well at the expected speed, thereby reducing the separation accuracy and efficiency. Summary of the Invention

While fixing the position of the moving plate 43, the magnetic conduction plate 13 attracts the sealing plate 8 to move downward to open the inside of the gas storage box 46. The gas inside the gas storage box 46 enters the inflation tank 48 through the air outlet pipe 47, and when pushing the piston rod 49 to move, it squeezes the compression spring 11. The piston rod 49 drives the toothed plate 410 to engage with the first gear 411 to rotate. The first gear 411 engages with the second gear 412 to rotate. The second gear 412 pushes the contact plate 413 restricted on its surface to fix the centrifuge tube, ensuring that the position of the centrifuge tube will not change during centrifugation.
