Description

  The present invention relates to a multi-chamber container.

  Conventionally, when two or more types of drugs are blended, there is a risk that the drugs will be altered due to changes over time due to drug interactions, so a method of mixing and preparing each component immediately before administration at the medical site has been adopted It had been. However, such mixing of drugs immediately before dosing has drawbacks such as microbial contamination, foreign matter mixing, error mixing, and rapid dosing. Therefore, at present, partition means such as a weak seal that can be peeled off by applying pressure are provided in the container body, and each unmixed drug is individually filled into a plurality of drug filling chambers partitioned by the partition means, immediately before administration. Many multi-chamber containers have been developed that can release the partitioning means and mix each medicine.

  Many of such multi-chamber containers are provided with partitioning means in the short direction so as to divide the inside of the container main body into two equal parts, and usually the partitioning means is provided until the drug mixing operation is performed. The container body is folded and stored in the vicinity of the center of the container body.

  When mixing the medicine using the multi-chamber container, firstly, the container body folded in half is returned to the original expanded state, and then the medicine filling chamber is pressed by hand or the like to release the partitioning means. Is done. Therefore, in the medicine mixing process using the multi-chamber container, it is necessary to separately perform two operations, that is, the operation of returning the container body to the expanded state and the operation of releasing the partitioning means (there is no patent document).

  However, the two operations are not only troublesome in the drug mixing process, but also the mouth plug and one drug filling chamber communicate with each other, so that the hook hole provided at the lower end of the container main body. If the multi-chamber container is suspended through a hook, or if the multi-chamber container is installed on an inclined surface with the cap facing downward, the hollow needle is inserted into the rubber stopper fixed to the drug discharge port. The unmixed medicine flows into the hollow needle through the medicine discharge pipe of the plug from one medicine filling chamber communicating with the hollow needle. For this reason, neglecting to press the drug filling chamber which is the second operation, there is a risk that the unmixed drug will be accidentally administered to the patient, and this is the case when the multi-chamber container is configured as described above. There is a problem in that it is impossible to prevent such medical accidents and ensure safety for patients.

  Therefore, in order to solve such problems, the present invention can administer the mixed medicine by performing only the operation of releasing the partitioning means in the medicine mixing process using the multi-chamber container. Providing a multi-chamber container in which the unmixed medicine filled in the medicine filling chamber before the release of the fluid does not flow into the hollow needle through the mouth plug, thereby realizing a simple operation in the medicine mixing process and partitioning. The aim is to avoid the risk of unmixed drugs being administered to a patient due to the unreleased means.
