Blood plasma collecting device and method for blood plasma replacement process

Abstract

The invention discloses a blood plasma collecting device for a blood plasma replacement process. The blood plasma collecting device comprises a collecting box and a placement barrel, wherein the collecting box is movably arranged in the placement barrel, a locating plate which extends onto the placement barrel is arranged at the top of the collecting box, the collecting box below the locating plate is made from a flexible material, and a stirring component for stirring blood plasma is arranged in the placement barrel. The lower part of the placement barrel is made from the flexible material, so that the stirring component can be used for indirectly stirring blood plasma through stirring the placement barrel, and clotting of the blood plasma is avoided; and the device is simple in structureand convenient to clean.

Description

technical field [0001] The invention relates to the field of plasma collection, in particular to a plasma collection device and method during plasma replacement. Background technique [0002] Plasma exchange is a process in which whole blood is taken out of the body and separated into plasma and cell components, the patient's plasma is discarded, and then plasma substitutes such as fresh plasma, albumin solution, and balance solution are replaced by the separated plasma and returned to the body at the same speed. , to achieve the purpose of reducing pathological damage and removing pathogenic substances. [0003] During the plasma replacement process, the plasma needs to be transferred into the plasma collection device. If the plasma is left in the plasma collection device for too long, the plasma will coagulate, and the coagulated plasma cannot be discharged from the plasma collection device, which will affect the quality of work. The patent application number is: CN201821...

AI Technical Summary

Problems solved by technology

[0003] In the process of plasma exchange, the plasma needs to be transferred into the plasma collection device. After the plasma is left in the plasma collection device for too long, the plasma will coagulate, and the coagulated plasma cannot be discharged from the plasma collection device, which will affect the quality of work.

The patent application number is: CN201821694672.7, although the patent can stir and heat the plasma, but its structure is complicated, and the plasma is easy to stick to the stirring device, resulting in waste of plasma, and it is not easy to clean the device
