Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fixing device for a blood bag in a centrifuge. Background Art

[0002] In the biomedical field, large amounts of blood, especially blood products, are often centrifuged. Selecting the right centrifuge container is crucial for the centrifugation effect, which directly affects the quality of subsequent blood products. Considering the safety of blood products, especially to reduce the probability of contamination, blood collection bags are usually placed directly into the centrifuge for centrifugation. However, because current blood collection bags are made of medical polyvinyl chloride, which is relatively soft, they are prone to deformation or rupture when placed directly into the centrifuge basket for centrifugation, resulting in poor or no centrifugation effect. For example, China has disclosed a "plasma collection device for centrifugal separation," with application number "CN201620875627.6." This device solves the problems of low safety level, unstable quality, lack of functionality, low plasma collection efficiency, and poor usability by providing a centrifuge chamber with a centrifuge cup, plasma layer, and blood cell layer that are sequentially wrapped and connected from the inside out. However, this device cannot secure the blood bag, absorb the vibration and shock generated during centrifugation, reduce the direct impact force on the blood bag, and thus reduce the risk of damage.
