FIG. 4 shows a problem to be solved by the prior art and the invention.
Is a partial schematic view of the blood bag 15 currently used,
Downstream of the filter 22 equipped with the connection pipe 21a (21b), blood component separation bags 24 and 25 connected via a connection pipe 22a (22b) are arranged. The collected blood is separated into each blood component by the filter 22,
The air in the filter 22 is separated from the blood component separation bag 24.
And it was not possible to remove these extra air.

When the blood bag 15 is subjected to a high-pressure steam sterilization treatment, the filter 22 temporarily expands thermally and becomes negative pressure when returning to the original shape at room temperature.
a, the blood transfusion port 27 and the connection tube 28 were sometimes sucked in and collapsed. As a result, the blood components cannot be transferred, and thus cannot be used for separating blood. Therefore, the present inventors have made intensive studies to solve the above problems, and have arrived at the following invention.
