Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical container equipped with a sterilizing filter for aseptically mixing a drug used for drip injection or the like with a drug solution such as dissolution, dilution or mixed drug. It is a thing. Here, the drug includes not only a solid agent such as powder but also a liquid agent, and the drug solution refers to a diluting solution, a solution, and a mixing drug solution of the drug.

[0002]

2. Description of the Related Art Conventionally, a drug which is very unstable in an aqueous solution is stored as a powdered drug in a vial having a rubber stopper. To administer these drugs to patients, inject the solution into the drug container with a syringe, etc., dissolve the drug, and then take out the solution with the drug dissolved again from the drug container with a syringe etc. and mix it into the infusion container. Was used. The same applies to the case of using a drug container that aseptically contains a liquid agent or the like that decomposes or deteriorates when sterilized by heat such as high-pressure steam sterilization.

However, in these series of operations,
In many cases, the communication needle is exposed to the outside world, which increases the chances of nosocomial infection. In addition, some drugs cannot be subjected to aseptic processing, and a problem occurs if the drugs are simply dissolved in a solution and mixed and injected into an infusion container. Therefore, there has been conventionally proposed a container containing a solution or a drug solution, which is provided with a connecting portion for connecting a vial containing a drug as sterilely as possible. The connecting portion is provided with connecting means such as a communicating needle or a rubber stopper for connecting to a container such as a vial, and the connecting needle and the rubber stopper surface of the connecting portion are aseptically sealed before use. For this reason, at the time of use, the inside of the container for storing the dissolution liquid and the container for storing the drug are communicated as sterilely as possible so that the dissolution liquid can aseptically flow into the drug.

However, even a container provided with such a connecting portion cannot be said to be completely sterile because there is a chance that the connecting means will be partially exposed to the outside world. Therefore, the applicant of the present application first provided a sterilization filter at the connection portion, and after the lysate flowed into the drug side, it was returned again to the lysate side container through the sterilization filter to make a completely sterile mixed injection liquid sterilization filter. Has proposed a liquid transfusing container having a connecting portion (see Japanese Patent Application No. 4-2.
38959).

[0005]

However, in a medical container equipped with such a sterilization filter, a lysate or the like passes through the sterilization filter and flows into the drug container, and then is returned to the drug solution container again. Has the inconvenience that it takes time because the chemical solution is passed through the sterilization filter twice. In particular, in a fixed-form drug container such as a vial, positive pressure is generated, and it becomes difficult for the drug solution to gradually flow in. Further, in such a conventional one, since the drip is performed after the mixing operation of the drug solution and the drug,
In case of emergency, inconvenience occurs. Therefore, an object of the present invention is to provide a medical container in which a drug and a drug solution are rapidly mixed and can be aseptically returned into the container.

[0006]

SUMMARY OF THE INVENTION The present invention comprises an atypical resin container body having means for communicating with a drug container, wherein a part of the drug solution in the container body is introduced into the drug container. In a medical container in which the drug solution is returned to the container body again after being mixed with the drug, a sterilizing filter is provided in a communication passage that connects the container body and the drug container, and the sterilizing filter is also provided. A bypass passage connecting the inside of the container body and the inside of the medicine container is provided, and when the medicine container is connected to the medicine container by the communication means, a part of the liquid medicine in the container body is in the medicine container. The above object is achieved by providing a medical container characterized in that the bypass passage can be closed when the chemical liquid returns again while being able to flow in through.

In the present invention, the bypass passage may be a bypass line that directly communicates with the container body, and the line is connected to a communication passage between the sterilization filter and the drug container. Further, there is one in which a blocking member for opening and closing the bypass line is provided in the communication path. In addition, the bypass line may be a flexible line that can be liquid-tightly closed by a holding jig.

Further, in the present invention, the bypass passage is made of a communicating member movably attached to the communicating passage, and the communicating member has a communicating needle portion at a tip thereof which communicates with the medicine container, and the communicating member has a communicating needle portion. In some cases, the needle portion pierces the drug container by moving a predetermined amount of the material, and the inside of the container body and the drug container directly communicate with each other.

The present invention can be characterized in that the medicine container is a resin container having an atypical shape. In the present invention, the drug container is a container having a typical shape, and the drug container or the communication passage is formed with an air release air introduction opening communicating with the outside,
The opening may be provided with an air filter.

Further, according to the present invention, there is one in which a communication port of a communication path connecting the sterilization filter and the container body is arranged in the container body in the vicinity of the discharge port.

[0011]

In the above medical container, first, it is connected to the drug container through the communication means attached to the container body, for example, the communication needle portion of the communication passage. Then, the drug solution in the medical container is promptly flown into the drug container and mixed with the drug using the bypass passage. When returning the inflowing drug solution again, the main body of the medical container is placed below with the bypass passage closed and returned to the inside of the medical container through the sterilization filter. Therefore, since the outward path for transferring the drug solution to the drug container side does not pass through the sterilization filter, it is possible to mix with the drug in an extremely short time.
Then, the chemical liquid to be returned again is returned to the inside of the container body in an aseptic state by the sterilization filter.

If the drug container has a typical shape,
It is possible to prevent negative pressure on the drug container side simply by providing an opening provided with an air filter in the communication passage or a part of the drug container, and even in the case of such a regular container, it smoothly returns to the medical container side. . Furthermore, by arranging a communication port such as a pipe for communicating the sterilization filter and the inside of the medical container near the discharge port of the medical container, it is possible to smoothly perform the drip operation simultaneously with the returning operation of the chemical solution. . That is, since the return chemical is guided by the communication pipe and flows out near the discharge port, the return chemical is diluted near the discharge port and is smoothly discharged as a drip solution from the discharge port, so that the mixing operation and the drip operation are performed at the same time. The operation time is shortened.
