The present invention relates to a blood bag and a manufacturing method thereof.

It is configured. The blood bag is formed by sandwiching two sheets of flexible synthetic resin between an upper mold having an edge of the bag and a flat plate (lower mold) and performing high-frequency welding. It was

夫もされていたが、調整が困難であった。However, in the blood bag, as shown in FIG. 4, only the upper side 23 of the bag-shaped main body 22 was inflated and the lower side 24 was flat. Further, in the vicinity of the welded portion 25 of the peripheral portion of the main body 22, there was a small amount of resin protruding portion 26 (resin reservoir), and the thickness tended to be thin (the protruding portion 26 usually has a width W 2 of 0.5 m).
m and the thickness D 2 were formed to about 0.4 mm. Therefore, when the blood bag 20 is subjected to a centrifugal separation process for separating blood components, the welded portion is easily peeled off, and there is a risk of puncture or the like. Further, the volume of the blood storage chamber formed inside the bag-shaped main body was small, and when loosening the platelets separated by the centrifugal separation process and settled to the bottom of the main body, it was difficult to stir and the platelets were not loosened easily. There was a risk that the platelets would be destroyed if they were forcibly loosened and collected. Further, as in the blood bag 30 shown in FIG. 5, the protrusion 36 is thickened to inflate the main body 32, but the adjustment is difficult.

It is good to form. In other words, the width W 1 is gradually increased from 0.6 mm to 1.2 mm from the side portion S of the body to the corner portion R and the bottom portion B, and the thickness D 1 is also formed from the body side portion S to the corner portion R. And gradually toward the bottom B 0.8
It is better to make it large from mm to 1.4 mm.

きた。Next, a method of using the blood bag 1 will be described. Body 2
Blood is collected from the donor through the blood collection needle 7 and the liquid transfer tube 8, and centrifugal force is applied under predetermined conditions to separate blood cells and plasma. Next, the communication piece 3 is broken, and the supernatant plasma component is stored in the blood component separation bag 9 via the connection tube (liquid transfer tube) 10 and the bag 9 is separated.
Are again subjected to centrifugation under predetermined conditions to precipitate platelets in plasma. The bag 9 is placed on a shaker and the platelets precipitated on the bottom of the bag 9 are loosened and collected while vibrating the bag 9. When centrifuging, it is confirmed that puncture does not occur at all because the protrusion 12 is formed thickly. Also, when loosening platelets, the blood storage chamber is wide so that it can be easily stirred. It was confirmed that the unraveling condition was good.
