Layering method for blood components of plasma, blood platelets and the like in high-speed centrifugal manner

Abstract

The invention provides a layering method for plasma, blood platelets, leukocytes and erythrocytes in a high-speed centrifugal manner. The method comprises the following steps that firstly, blood of apatient is quantitatively introduced into a test tube assembly for storage, the test tube assembly containing the blood is installed and inserted into a packaging mechanism, the test tube assembly andthe packaging mechanism are in an isolated state, and a liquid containing part formed by the test tube assembly and the packaging mechanism is integrally installed on a centrifugation device; then, the centrifugation device is started, and the centrifugation device is started to drive an outer-layer tube and the packaging mechanism to rotate to be centrifuged until the blood in the outer-layer tube is centrifuged layered and sequentially comprises a plasma layer, a blood platelet layer, a leukocyte layer and an erythrocyte layer from top to bottom; and finally, an automatic control device isused for switching the state between the test tube assembly and the packaging mechanism from an isolated state to a communicating state, the test tube assembly sequentially discharges all the layers of the layered blood from top to bottom into the packaging mechanism for independent containing, and the plasma layer, the blood platelet layer, the leukocyte layer and the erythrocyte layer which areindependently contained are taken out for later use by a user.

Description

technical field The invention relates to a method for stratifying blood plasma, platelets, white blood cells and red blood cells by means of high-speed centrifugation. Background technique Blood centrifuges are widely used in clinical medicine, biochemistry, immunology and other fields, and are routine instruments for centrifugal precipitation in laboratories. It is mainly used for the determination of the hematocrit value in blood, the separation of trace blood and trace solution, etc. It is one of the preferred products for genetic, protein and nucleic acid laboratories. The common blood centrifuge in the prior art is relatively poor in blood subpackaging, and the various layers of liquid are directly sucked out for testing through a straw. Accuracy will have some impact. Contents of the invention In order to solve the deficiencies of the prior art, the object of the present invention is to provide an automatic independent packaging blood centrifugation method with ...
