Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infusion container used for drip treatment, and more particularly to an infusion container which can be used by aseptically adjusting a drug solution during treatment.

[0002]

2. Description of the Related Art Powders such as antibiotics and anticancer agents which are deteriorated when stored in liquid form or freeze-dried drugs are generally contained in vials and used by being dissolved in a solution when performing drip treatment. .. Conventionally, such powders or freeze-dried agents are communicated with a vial containing a drug and a container containing a solution using a communication tool such as a double-ended needle or a connecting pipe, and the solution is transferred to the container containing the drug. , A drug is dissolved in a solution to prepare a drug solution. However, this operation is complicated and time-consuming, and since the operation for making a communication hole in the container containing the drug is carried out, the drug solution to be prepared may be contaminated.

As a means for solving such a problem, Japanese Patent Laid-Open No.
In the 2-1227 publication, it is easy to establish communication between a drug container and a solution or diluent (hereinafter collectively referred to as "solution") container,
There has been proposed an infusion container capable of reliably preventing contamination of a prepared drug solution. This infusion container is, as shown in FIG. 6, a flexible container 40 in which a solution is stored, a capsule 41 connected to the flexible container 40, and a drug container 42 held in the capsule 41. And a communication means 43 for communicating the inside of the flexible container 40 and the inside of the medicine container 42. The flexible container 40 has a liquid passage 45 with a closure membrane 44 at the uppermost end, while the mouth 46 of the drug container 42 is sealed with a pierceable stopper. The communication means 43 has a hub 47 in the middle.
And a hollow puncture needle 48 having blade edges at both ends, and after the stopper of the drug container 42 has been pierced by one blade of the puncture needle 48, the flexible container 40 by the other blade of the puncture needle 48. Closure membrane
The braking means 49 controls the communication sequence so that 44 is pierced.

By the braking means 49, the closure film 44 of the flexible container 40 is pierced after the stopper of the drug container 42 is pierced. For this piercing operation, by covering the capsule 41 with a cap 51 having a cam 50 as shown in FIG. 7 as an example, the cam 50 abuts the cam follower portion 53 of the pressing member 52 and is pressed by the rotation of the cap 51. The member 52 is adapted to move downward. At that time, the medicine container 42 is configured so as not to be rotatable but axially movable so as to move up and down by fitting the guide rod 54 of the pressing member 52 and the guide groove 55 formed on the inner surface of the capsule 41.

[0005]

However, although such an infusion container has been considerably improved in terms of prevention of contamination of the internal drug and simplification of communication between the drug container and the solution container, the parts of the braking means 49 are complicated. In addition, there is a problem that the number of parts is large and communication is required by rotating the cap 51, which requires a considerable amount of work. An object of the present invention is to provide an infusion container having a very simple communication operation and a small number of parts.

[0006]

According to the present invention, there is provided a liquid container having a liquid passage portion and a drug solution outlet and containing a solution or a diluent therein, a drug container containing a drug therein, and the liquid container. Communication means for aseptically communicating the container and the drug container,
And an infusion container composed of a bag-shaped packaging material in which the liquid storage container, the communication means, and the drug container are arranged in this order and are aseptically sealed, and the packaging material is the liquid storage container side and the drug container side. Is a transfusion container having holes for hanging on the respective seal surfaces. Further, in the present invention, in the above-mentioned infusion container, the seal surface on the side of the liquid container is formed so that the accommodating portion of the drug solution outlet is narrow, and a cut line is provided so as to cross the accommodating portion of the drug solution outlet. It is an infusion container.

Further, the present invention provides the above-mentioned infusion container, in which a dissolving liquid or a diluting liquid is contained, a liquid passage portion having a closing film is provided at one end, and a chemical liquid outlet is provided at the other end. And a plurality of annular ribs on the outer peripheral surface of the liquid passage portion,
A bottle in which a substantially vertical guide is provided on the annular rib; and a substantially cylindrical first member having one open end including a first cylinder and a bottom wall formed at one end of the first cylinder. ,
A communication portion including a second cylindrical body and a partition member formed inside the second cylindrical body and having a substantially cylindrical second member having open both ends, and a mouth portion sealed with a pierceable plug. A drug container, and a packaging material obtained by aseptically sealing the bottle, the communication part and the drug container, wherein the first member includes a hollow puncture needle having a hub in the middle and blade edges at both ends, Further, it has an inner ring-shaped projection at the open side end portion that engages with the ring-shaped rib of the bottle, and further, at least 1 is formed on the first cylindrical body.
Two notches are formed substantially parallel to the axial direction, and at least one outer protrusion is formed on the outer peripheral surface thereof, and the partition wall of the second member has an inner diameter substantially the same as the outer diameter of the puncture needle. The infusion container has an opening formed therein, and a hole in which the outer projection of the first member fits is formed in the bottle-side second cylinder.

Furthermore, the present invention is the above-mentioned infusion container, wherein a pair of cuts of the first member are formed axially symmetrically. Further, the present invention provides the infusion container,
The infusion container has an air vent hole formed in the bottom wall of the first member. Further, the present invention is the above-mentioned infusion container, wherein a rubber cap is put on the bottle-side cutting edge of the puncture needle.

[0009]

In the infusion container of the present invention, since the hanging holes are provided on both the seal surface on the liquid container side and the seal surface on the drug container side, the infusion container is simply a hanger or the like. The drug can be dissolved simply by suspending it in. That is, when the infusion container is first hung by hanging the suspension hole on the side of the liquid container on the hanger and the liquid container and the drug container are communicated by the communication means, the solution in the liquid container naturally falls and the drug container. And the drug in the drug container is dissolved.
Next, when the infusion container is hung by hanging the suspension hole on the side of the drug container on a hanger, the prepared drug solution is transferred from the drug container to the liquid storage container by spontaneous fall. When performing fluid therapy,
The infusion set may be connected to the drug solution outlet of the liquid container when all the drug solution is transferred to the liquid container.

Further, in the infusion container of FIG. 2, the inside of the medicine container and the inside of the bottle can be communicated by the action of the communicating portion by simply pushing the bottle toward the medicine container. That is, when pushing the bottle towards the drug container,
Since the member is deformed inward in the axial direction by the outer protrusion and the notch, it slides inside the second member. As a result, the stopper of the drug container is first pierced by the puncture needle. In this case, the annular rib of the liquid passage portion of the bottle and the inner annular protrusion of the first member are in engagement with each other, and the puncture needle erroneously pierces the closure membrane of the bottle while the first member is sliding. There is no such thing.

When the bottle is further pushed toward the medicine container after the stopper of the medicine container is pierced, the bottom wall of the first member reaches the partition wall of the second member and the sliding of the first member is stopped. At this time, the outer protrusion of the first member fits into the hole of the second member, the first member returns to its original shape, and the annular rib of the bottle is disengaged from the inner protrusion of the first member. When the first member is further pushed, the bottle moves toward the puncture needle, and the puncture needle pierces the closure membrane of the bottle.
