  For example, some of the drug solutions administered to patients by intravenous injection may be unstable and change with time if they are formulated beforehand. It is widely known that such a medical solution uses a medical multi-chamber container in which the medical solution is separately stored in a plurality of storage sections partitioned by partition sections to which components prior to compounding are weakly attached in a peelable manner. In this medical multi-chamber container, the compartments are peeled off by applying pressure from the outside, and the storage parts are communicated with each other to mix the medicines (hereinafter referred to as opening work). Then, with the hook suspended in the hanging hole to suspend the container body, the needle plug connected to the catheter is inserted into the rubber plug sealing the drug solution outlet, and the injection needle attached to the tip of the catheter Administered to patients from

  However, such a medical multi-chamber container is provided with a chemical solution outlet in one storage unit, and forgets the opening operation, does not peel off the partition, and the administration of the chemical solution is performed even if the chemical solutions are not mixed. Because it can be done, there is a risk of administering unmixed drug solutions to the patient. Therefore, in order to prevent the forgetting of opening operation, it is equipped with a peelable opening confirmation seal attached to close the hanging suspension hole of the medical multi-chamber container, and this opening confirmation seal Patent Document 1 discloses a medical multi-chamber container which has the same for alerting the user to mix medicines in the medical multi-chamber container.

  According to Patent Document 1, since the hanging hanging hole is closed by the seal for opening confirmation, the medical multi-chamber container can not be suspended on the hook, and there was a warning effect for preventing the opening operation forgetting . However, since the entire opening confirmation seal is attached to the container body, there is a problem that it is bothersome and troublesome work to take the opening confirmation seal. In addition, if the seal for opening confirmation is peeled off, the display unit prompting the mixing of the chemical solution disappears in the container main body, and the alerting effect is not sufficiently exerted, and the opening confirmation seal is removed before peeling and opening the partition. If it peels off, further alerting becomes less hopeful. In addition, medical workers may perform treatment for multiple patients at the same time, and perform other work while leaving the medical double-chamber container which has been prepared for use, and then leaving the medical double-room container. In some cases, preparation for use may be resumed, or in the case other healthcare workers may resume preparation for use. In such a case, there is a risk that the liquid medicine administration to the patient may be started in a state where the plurality of storage units are not in communication, misunderstanding that the opening operation has been completed.
