Embodiment 1

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

Embodiment 2

[0053] Such as Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown in the figure, a separation soft bag used to improve the separation efficiency during continuous separation of plasma includes a bag body and a pipeline connected to it. The bag body is a rectangular medical plastic bag with a length of 50cm and a width of 10cm. On one of its long sides, there are plasma pipelines, whole blood vessel pipelines and blood cell pipelines connected to the inside and outside respectively.

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 blood continuous centrifugal separation equipment. Background technique [0002] Whether it is scientific research, medical clinical practice or industrial production, and more occasions, it is necessary to separate blood, such as separating a single component from whole blood, usually using centrifugation to separate various single components from blood for use Clinical treatment, scientific research or preparation of raw materials and other occasions. The most common method is to separate red blood cells, granulocytes, monocytes, platelets, and plasma from whole blood through a centrifuge system, or wash thawed frozen red blood cells 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-mentioned system includes a centrifuge, an infusion pum...
