Background

Medical clinical practice and research institutions often require the use of centrifugation to separate blood, e.g., separate individual components from whole blood for clinical treatment or scientific research. The most common method is to place the collected whole blood in a blood bag and then place the blood bag in a centrifuge for centrifugation. However, in the centrifugal separation process, the blood bag is irregularly displaced, so that the blood bag collapses and accumulates towards the bottom of the centrifugal cup, as a result, the sample in the blood bag has poor layering effect and an unclear interface, and the red blood cells or blood plasma discharge process damages boundary lines of various layers after centrifugation, thereby affecting the overall separation effect. To this end, we propose a mounting module for a blood bag in a centrifuge.
