[0002] Before performing operations such as cross-matching blood tests in hospitals or laboratories, it is necessary to manually transfer the blood in the storage vessel to a test tube, and install the test tube into a special centrifuge device for centrifugation, which is a complicated operation
And because the scissors used to unseal the storage vessel will be reused, it is easy to cause blood contamination in the storage vessel, which will lead to inaccurate test results

Abstract
The invention discloses a blood extraction centrifuge and a centrifugal extraction method. Before performing the operation such as the cross-matching tests, the blood in a blood reservoir is transferred to a test tube and is subjected to centrifugation, and the operation is complicated. The blood extracting centrifuge of the invention comprises an upper shell, a lower shell, a needle injector, a blood collection device, a thimble, a base, a centrifugal mechanism, test tubes, an upper needle gripper, a tube gripper, a tube unloading gripper, and a test tube storage box and a waste storage tube-collection box. The needle injector includes an upper spit shell, a lower spit shell, a needle, a push rod, a pusher holder and a needle driving member. The blood collection device includes a pin moving block, an upper clamping tube block, a lower clamping tube block, an upper clamping tube screw rod, a lower clamping tube screw rod, a blood collecting tube, a blood collecting electric push rod, apin moving screw rod, a first blood collecting motor, a second blood collection motor and a third blood collection motor. The centrifuge can transfer the blood in the blood storage tube into the testtube and complete the centrifugal layering work of the blood, which simplifies the process of taking blood by the medical staff.
Description
technical field [0001] The invention belongs to the technical field of blood detection, and in particular relates to a blood extraction centrifuge and an extraction centrifugation method thereof. Background technique [0002] Before performing operations such as cross-matching blood tests in hospitals or laboratories, it is necessary to manually transfer the blood in the storage vessel to a test tube, and install the test tube into a special centrifuge device for centrifugation, which is a relatively complicated operation. And because the scissors used to unseal the storage vessel will be reused, it is easy to cause blood contamination in the storage vessel, which in turn leads to inaccurate test results. Contents of the invention [0003] The object of the present invention is to provide a blood extraction centrifuge and an extraction centrifugation method thereof. [0004] The blood extracting centrifuge of the present invention comprises an upper shell, a lower shell, ...
