A particular problem at the time of transportation is that a so-called kink problem occurs in which the tube of the blood circulation circuit is subjected to an excessive force and remains in a folded shape. When stored for a long time with kinks, the tube made of synthetic resin, in particular, is used with the tube lumen closed, which is inconvenient when performing priming work or extracorporeal blood circulation. In order to prevent such inconvenience, when the packaging member of Patent Document 1 is used, it is generally performed to be housed and protected in a separate transport box.

The packaging member of Patent Document 2 is a resin box that can accommodate and protect a blood circulation circuit. When this packaging member is used, after the blood circulation circuit is placed inside the packaging member, each component is fixed with a hook-and-loop fastener or an adhesive tape. This prevents each part of the blood circulation circuit from inadvertently moving inside the box, thereby preventing damage to the blood circulation circuit.
