Separator disk on multi-cell component mix liquid separating system and application method of the same

Abstract

The invention relates to a separation disc on a multi-cell component mixed liquid separating system. The separation disc comprises a durable hard base disc and a disposable soft bag, wherein, a round disc composed of an inner core and a base seat is arranged on the hard base disc, a continuous cavity gap circling the axle of the centre of circle of the hard base disc and having a head part and a tail part which are not sealed is formed between the inner core and the base seat, the space between the outer side wall of the cavity gap and the outer side wall of the hard base disc is transparent, the soft bag adopts a single cavity structure equipped with an inlet pipe and an outlet pipe, and the soft bag can be arranged into the cavity gap; the application method comprises the following steps: the separation disc is positioned in the separating system to form a lamella of a single component through each component in the centrifuged and mixed liquid and according to the difference of the density, and then the lamella is accumulated to be thicker to extract the target component. The separation of the multi-cell component mixed liquid, for example, whole blood, by utilizing the separating system having the separation disc of the invention has the advantages of low cost, high preparation purity and high separating efficiency.

Description

technical field [0001] The invention relates to centrifugal separation of mixed liquid components, in particular to a separation disc on a multi-cell component mixed liquid separation system, and a method for separating a single component in a multi-cellular mixed liquid by using the separation system containing the separation disc. Background technique [0002] Blood collection institutions and scientific research institutions usually use centrifugation to separate various single components from the mixed liquid of multicellular components for clinical treatment, scientific research or preparation of raw materials and other applications. Most commonly, whole blood is separated from red blood cells, granulocytes, monocytes, platelets, and plasma, or thawed frozen red blood cells are washed to separate red blood cells and washing fluid. [0003] Conventional separation systems for processing mixed liquids of multicellular components use devices such as centrifuges, infusion p...

AI Technical Summary

Problems solved by technology

In practice, as a disposable soft bag, the structure is relatively complex, the production cost is high, and the use cost also increases; the concentric circle separation structure will cause the concentric circle layer distribution of each component, which is not easy to enrich specific components. Therefore, when extracting specific components, especially those with low content, the control accuracy of the equipment is high, time-consuming and laborious, and the efficiency is low; if it is used in automatic blood collection, it will easily cause a large amount of extracorporeal blood in the donor, which is not conducive to Healthy body
