Description

Plasma collecting system and method

Technical Field

The invention relates to the field of plasma collection, in particular to a plasma collection system and a plasma collection method applied to a plasma collector.

Background

The existing blood plasma collector separates different blood components by high-speed centrifugation according to the specific gravity difference of the blood components. The method comprises the steps of mixing the exported blood with a certain proportion of anticoagulant, inputting the mixture into a separation cup, rotating the separation cup at a high speed under the driving of a plasma collection machine, and layering blood components with different specific gravities, such as red blood cells, plasma, platelets and the like in the blood in the separation cup under the action of centrifugal force, so that the purpose of collecting the plasma is achieved.

However, in a closed system with the entire collection, when one plasma collection bag is full of plasma, plasma collection can no longer be performed. If more blood plasma is required to be collected, the whole set of pipeline consumables needs to be replaced, so that the blood plasma collection cost is high, and the labor intensity of medical staff is increased. With respect to the collection of the completed plasma, during use, if a single plasma collection bag is unsealed once, the plasma in the unsealed plasma collection bag must be completely processed. When plasma use is incomplete, storage of the remaining plasma is relatively complicated. In addition, after the plasma collection is completed, blood products still remain in the pipeline consumables, which not only causes the waste of blood resources, but also causes the pollution to the environment.
