Embodiment 1

[0050] Such as Figure 4 , Figure 5 , Image 6 with Figure 7 As shown in the figure, a separation soft bag used to improve separation efficiency during continuous plasma separation includes a bag body and a pipeline connected to it. The bag body is a rectangular medical plastic bag with a length of 50 cm and a width of 10 cm. A blood plasma pipeline, a whole blood vessel circuit, and a blood cell pipeline connecting the inside and outside are respectively arranged on one long side. The starting end of the blood plasma pipeline is located at the plasma port at the end of the short side of the bag, about 0.5 cm from the short side. The whole blood vessel is connected to the blood inlet in the middle of the bag body, and the start end of the blood cell line is located at the blood cell opening at the other short side end of the bag body, and the distance from the short side is about 0.5 cm; in the separation soft bag There is a dam structure that blocks blood flow between the in...

Abstract

The invention relates to a separation soft bag for improving separating efficiency during plasma continuous separation. Plasma continuous centrifugal separation is performed inside a curved surface body container, a separating lacuna is arranged inside the curved surface body container, the separating lacuna adopts a curved surface body structure with an outer wall and an inner wall, the separation soft bag is accommodated inside the separating lacuna, the separation soft bag structurally comprises a bag body and a pipeline connected with the bag body, the separation soft bag is a rectangular soft medical plastic bag, and a plasma pipeline, a whole blood pipeline and a blood corpuscle pipeline communicated with the inside and the outside of the separation soft bag are arranged on one side of the long edge of the separation soft bag. A dam body structure is designed inside the separation soft bag, the structure can be used for adjusting the liquid stream direction inside the separation soft bag, and further the plasma separating efficiency is improved. According to the invention, the unique structure for guiding liquid stream is designed inside the separation soft bag and used for continuous plasmaphoresis so as to improve the separating efficiency.

Description

Technical field [0001] The invention relates to blood separation technology, in particular to a separation soft bag applied to a blood continuous centrifugal separation device. Background technique [0002] Whether it is scientific research, medical clinical practice, industrial production, and more occasions, blood needs to be separated. For example, single components are separated from whole blood. Centrifugation is usually used to separate various single components from blood. Occasions such as clinical treatment, scientific research or preparation of raw materials. The most common is to separate whole blood through a centrifugal separation system to separate red blood cells, granulocytes, monocytes, platelets and plasma, or to wash frozen red blood cells after thawing to separate red blood cells and washing fluid. [0003] The working principle of the continuous centrifugal separation system is: the main structure of the above system includes a centrifuge, an infusion pump...
