Description

  The present invention relates to a medical multi-chamber container that is divided into two drug chambers by a peelable weak seal portion and each drug chamber is filled with a drug.

Among drugs that administer nutritional components intravenously to patients, there are unstable drugs that tend to change over time when pre-mixed. For example, when an amino acid solution and a glucose solution are blended and stored in advance, the mixed solution is colored (brown) by the Maillard reaction. Moreover, when a calcium compound is blended with a phosphate compound, precipitation of calcium phosphate occurs in a solution having a high pH, and the product value is significantly reduced. When such a drug is administered to a patient, for example, as shown in Japanese Patent No. 2675075 (patent document 1), a medical multi-chamber container that individually accommodates components before mixing is used, and then mixed before administration. Is starting to do.
This medical multi-chamber container includes a plurality of chambers for individually storing different component drugs, and a partition weak seal that separates the chambers and peels and opens them by pressure from the outside.
However, in many cases, the multiple medical containers contain the liquid agent in the storage part on the discharge port side, and the bottle needle is inserted into the rubber stopper without peeling off the weak seal for partitioning, and the liquid agent is discharged from the discharge port. There is a possibility of taking it out.
For this reason, a method has been devised to ensure that drugs stored in each storage unit are mixed and then administered to the patient, and to prevent accidents in which the drug is administered to the patient without accidental mixing. For example, as shown in Japanese Patent Laid-Open No. 9-327498 (Patent Document 2) and Japanese Patent Application Laid-Open No. 2002-136570 (Patent Document 3), a weak seal portion for preventing communication is provided that separates a medicine discharge port from a compartment for storing the medicine. A multi-chamber container has been proposed.

Japanese Patent No. 2675075 JP-A-9-327498 JP 2002-136570 A

In the ones shown in Patent Documents 2 and 3, the possibility of inserting the bottle needle into the stopper and taking out the liquid agent from the discharge port without peeling off the partitioning weak seal portion is considerably reduced. However, adhesion due to blocking occurs between the weak seal portion for blocking communication that separates the drug discharge port and the compartment for storing the drug, and conversely, weak communication for blocking communication due to the proximity to the drug discharge port. A seal failure may occur in the seal portion. When adhesion due to blocking occurs, it takes time to remove the weak seal portion for communication inhibition. In addition, when a poor seal occurs at the weak seal portion for inhibiting communication, there is a concern that the medicine is administered without peeling off the weak seal for partitioning. In addition, it is considered possible to prevent blocking by allowing a certain amount of liquid to exist between the weak seal portion for preventing communication and the medicine discharge port, but in this case, there is a risk that only the existing liquid is administered. .

The weak seal portion 10 for inhibiting communication is detachable, and inhibits communication between the first drug chamber 21 and the discharge port 3 in a state where the weak seal portion 10 is not peeled. A third chamber 23 isolated from the first drug chamber 21 is formed by the weak seal portion 10 for inhibiting communication. That is, a space (third chamber 23) is formed by the weak seal portion 10 for inhibiting communication, the discharge port 3, and the blocking portions 6 (6a, 6b). This space (third room) 23 is an empty room. However, it is preferable that a liquid that is harmless even when administered to a living body (for example, water or physiological saline) is added to the third chamber. By putting the liquid in the third chamber 23 in this way, the sterilization inside the third chamber is ensured. The amount of liquid placed in the third chamber 23 varies depending on the size of the third chamber, but is preferably about 0.1 to 0.5 ml. Moreover, it is preferable that the addition amount of the liquid per 1 ml capacity of the third chamber is about 0.02 to 0.1 ml. The weak seal portion 10 for inhibiting communication can be formed by heat-sealing a sheet material in a band shape (thermal fusion, high frequency fusion, ultrasonic fusion, etc.).

Then, 0.005 to 0.1 ml of liquid is added per 1 ml of volume in the space formed by the weak seal portion 10 for inhibiting communication, the discharge port 3 and the lower end side seal portion 6.
Like this medical multi-chamber container 1, by providing the weak seal portion 10 for inhibiting communication between the first drug chamber 21 and the discharge port 3 and capable of being peeled off, the weak seal portion 9 for partitioning is provided. It is preferable that only the first medicine in the first medicine chamber 21 is prevented from being administered without being peeled off. However, a space (third chamber 23) is formed by providing the weak seal portion 10 for inhibiting communication. Since the medicine discharged from the multi-chamber container 1 passes through this space, it is necessary to ensure sterilization.
Therefore, the medical multi-chamber container of the present invention provides a medical multi-chamber container that can surely sterilize the space formed by providing the above-described weak communication seal 10 for inhibiting communication.
In order to achieve this object, as described above, a small amount of liquid is added in the space 23 formed by providing the weak seal portion 10 for preventing communication. As the liquid, a liquid that is harmless even when administered to a living body (for example, water or physiological saline) is used. Then, in this state where a small amount of liquid is added (encapsulated) in the space 23 formed by providing the weak seal portion 10 for preventing communication, the added liquid is sterilized by high-pressure steam sterilization. Then, it is vaporized in the third chamber 23 which is a closed space, and the inner surface and the space in the third chamber 23 are sterilized. The amount of liquid added to the third chamber 23 is preferably 0.005 ml to 0.1 ml per 1 ml volume in the space of the third chamber. In particular, it is desirable that the volume is 0.01 to 0.05 ml per 1 ml of volume in the space of the third chamber. As described above, water (for example, sterile water, RO water, distilled water), physiological saline and the like are preferable as the liquid to be added.
