Abstract

The invention provides a blood sample separation method and a blood sample separation device. The blood sample separation device comprises a sample separation needle, a puncture needle and a driving mechanism connected with the sample separation needle and the puncture needle, the puncture needle is provided with a hollow structure, and the sample separation needle is arranged in the hollow structure in a penetrating mode. The method comprises the steps that the driving mechanism drives the puncture needle to penetrate through a test tube cover of a target test tube and drives the sample separation needle to move downwards in the hollow structure of the puncture needle; serum in the target test tube is taken by the sample separation needle; the driving mechanism drives the sample separation needle to move upwards in the hollow structure of the puncture needle and drives the puncture needle to move upwards to leave the test tube cover of the target test tube. The puncture needle penetrates through the test tube cover of the test tube, and then the sample separation needle moves downwards in the hollow structure of the puncture needle to take serum in the test tube, so that a blood sample can be taken without taking off the test tube cover, the test tube cover covers the tube body of the test tube after the blood sample is taken, a cover or a film does not need to be added, biological safety risks can be effectively avoided, the workload is reduced, and the cost is saved.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a blood sampling method and blood sampling equipment. Background technique [0002] For different types of people with different conditions, hospitals often adopt different strategies when collecting blood for them. For example, infants, frail elderly, or critically ill patients, the hospital often draws less blood for them to avoid excessive blood collection. More negative impacts on their bodies, and the testing items of these patients will not be less, the strategy adopted by the hospital is to divide their blood samples to support parallel testing of different business items, rather than each All business items consume one tube or more of blood samples, so sample splitting is more common in hospitals. [0003] Sample separation is divided into manual sampling and instrument automatic sampling. Manual sampling is inefficient and the results of sampling are i...
