Abstract

The invention relates to the technical field of blood collection, a method and device for collecting blood plasma for clinical medicine, comprising the following steps: connecting a blood collection needle to an outer tube for collecting whole blood; , collect a total of 3ml-5ml whole blood into the whole blood collection outer tube; hold the whole blood collection outer tube and shake it left and right for 20s-40s, so that the internal whole blood and anticoagulant are fully mixed; place the whole blood collection outer tube on the rack After standing still for 4min-6min, the whole blood is pressure-filtered with a push assembly, and the filtered plasma is collected into a plasma collection tube; the plasma collection tube is removed, and then sealed for use. The process of the invention is simple, easy to use, can effectively improve the collection efficiency of plasma, and reduce the workload of medical personnel.

Description

technical field

[0001] The invention relates to the technical field of blood collection, in particular to a plasma collection method and device for clinical medicine. Background technique

[0002] Blood samples used by medical institutions for clinical testing are generally obtained by collecting blood from human veins, arteries, or peripherals (finger tips, heels, or earlobes). The types of blood samples are divided into whole blood, serum, and plasma. Plasma is a light yellow liquid that does not contain blood-formed components after blood is isolated from the body and undergoes anticoagulant treatment and natural precipitation or centrifugation. Plasma samples are widely used in clinical experiments, and can be used to determine the biochemical components, immunological indicators, coagulation function and gene analysis of human blood, etc.

[0003] Traditional plasma collection is mostly through whole blood, and then centrifuged to obtain plasma. Because the centrifuge...
