This invention belongs to the field of medical device technology and discloses a blood bag with built-in tubing and its compression separation method for separating plasma with chylous stratification after high-speed centrifugation. The bag includes a bag body and a tubular assembly disposed on the end face opposite to the side of the bag body that bears the centrifugal force during centrifugation. The tubular assembly includes a separation tube extending into the bag body with its opening always located at the bottom of the bag body on the opposite side of the fixed end. The separation tube has a higher hardness than the bag body. The method involves removing and fixing the bag body after centrifugation, where the upper chyle layer and lower plasma layer are separated. Then, the plasma is pushed out from both sides of the larger area of ​​the bag body by manual squeezing or external squeezing. This invention has a simple structure and low cost, but can avoid the influence of centrifugation while recovering and reusing plasma with high chyle content that is difficult to utilize.
