The purpose of the present invention is to provide a multi-chamber vessel configured so as to be capable of: ensuring the opening order of a multi-chamber vessel used for transfusions, etc., said opening order being the initial opening of a weak-seal section between partitioned chambers, followed by the opening of a weak-seal section of a small vessel; and reliably preventing operation error, namely transfusion using only some of the medicine. The multi-chamber vessel comprises an outer bag (10) and an inner bag (32). The outer bag (10) comprises a weak-seal section (28) as a first partition wall and the interior of the outer bag is partitioned by the weak-seal section (28) into partitioned chambers (29, 30) that house each liquid medicine. The inner bag (32) has the outer perimeter thereof sealed by a weak-seal section (38) and houses medicine therein. All or part of the weak-seal section (38) also serves as a second partition wall separating a lower-side partitioned chamber (30) from a discharge control chamber (40). The external pressure that opens the weak-seal section (38) of the inner bag (32) is set greater than the external pressure that opens the weak-seal section (28) that separates the partitioned chambers (29, 30). The weak-seal section (28) is opened, then the seal of the inner bag (32) is opened, as a result of the external pressure on the liquid medicine housed inside the outer bag (10). |
