Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a mixing mechanism for infusion solutions for drip injection used in medical institutions.

[0002]

2. Description of the Related Art Conventionally, in medical institutions, powdered or lyophilized medicines contained in glass bottles are dissolved in a liquid such as physiological saline and used for infusion as an infusion. At that time, mixing and dissolution were performed using a connecting pipe, a double-headed needle, etc., but not only the work was complicated, but there was also the risk of foreign matter such as rubber powder being mixed in and chemical contamination.

In order to solve the above-mentioned drawbacks of the conventional infusion mixing method, as shown in Japanese Patent Publication No. 61-501129, a capsule containing a drug container and a flexible container containing a dissolving liquid are connected by a tube. In the tube, a hollow puncture needle is provided on the drug container side, and a flexible breaking member is provided on the flexible container side from the outside. In use, first, the drug capsule is pushed down, the rubber stopper of the drug container is pierced with a puncture needle, and then the breaking member is bent from the outside to break and the inside of the tube is opened, and these are mixed with the outside air. Although there was no contact, there were problems such as not only complicated operation but also incomplete opening and mixing of foreign matter.

Further, for the purpose of solving the above-mentioned drawback, it is described in Japanese Patent Laid-Open No. 2-1277, and as shown in FIG. 2, it is sealed with a flexible liquid container having a closing membrane at the upper end and a stopper. The drug containers are connected by a sealed passage that communicates the insides of the two, and a hollow puncture needle having a hub in the middle and blade tips at both ends in the passage, and a stopper of the drug container by one of the blades of the puncture needle. It is characterized in that it has a control means for controlling the order of communication so that the closing film of the flexible liquid container is pierced by one of the puncture needles after it is completely pierced.

However, even in this method, the operation is slightly simplified, but not only the number of members is large and the cost is high, but also the possibility of mixing powder of rubber or the like at the time of opening the rubber stopper or the like, and the mixing work. There are many drawbacks such as delay and other problems, such as plastic, glass, metal, rubber, etc., which are almost impossible to separate and discard after disposal.

[0006]

As described above, the conventional infusion mixing container does not come into contact with the outside air, but the operation is complicated,
There were many difficulties such as the complexity of the assembly members and the difficulty of waste disposal. The present invention has been made for the purpose of solving these problems, and providing an infusion mixture container in which complete mixing is performed by a simple operation, cost is low, and post-treatment is easy.

[0007]

The structure of the present invention will be described with reference to the drawings showing the embodiments. A flexible container 2 containing a drug container 1 whose mouth is sealed by an elastic stopper 11 and a drug dissolving or diluting liquid and having a sealing diaphragm 21 at its upper end is connected to a connecting pipe material 3 in a sealed state. At the time of connection, the fixing protrusion 41 provided at one end is press-fitted into the hole 12 provided in advance at the outer surface of the medicine stopper 11 at the center of the connecting member 3, and the flexible container is provided at the other end. The moving body 4 is manually advanced by a linear movement mechanism by a cam 43 provided on the outer periphery of the moving body 4 having a sharp protruding portion 42 for breaking through the sealing diaphragm 21 of 2 and a fixed cam 33 provided in the connecting pipe material 3. Let

That is, at this time, the stopper of the drug container 1 and the breakthrough of the diaphragm of the liquid container 2 are simultaneously performed by only one operation. That is, since the drug container is completely unplugged and the flexible container is pierced through the diaphragm almost at the same time, there is no fear of leakage to other people, and unlike the communication means using a puncture needle, a large amount of mutual mixing is extremely smooth with a simple operation. Done.

[0009]

EXAMPLES The present invention will be described below with reference to examples. Example 1. As shown in the partial cross-sectional views of FIG. 3A before the mixing operation and FIG. 3B after the operation, the space between the drug container 1 and the outer cylinder portion 22 of the diaphragm 21 holding portion of the liquid flexible container 2 is described above. A fixed cam provided on the connecting pipe member 3 for fixing the opening of the drug container 1 in a sealed manner by connecting the mover 4 having one end fixed to the stopper and attached with the up / down cam as shown in FIG. It is to be inserted into 33.

It should be noted that it is effective to provide the moving element 4 with a sharp protrusion 42 for piercing the diaphragm and a through hole 44 penetrating the moving element 4 in order to improve the flow of the liquid. Further, on the outside of the drug container 1, a covering container cover 13 and a suspension ring for infusion are provided.
Providing 14 is also effective. Further, the contact portions 35, 36, etc. of the medicine container 1, the container cover 13, the connecting pipe member 3, and the flexible container 2 are provided with projection fitting portions and packing in order to prevent leakage during shaking during mixing. That is also effective.

Embodiment 2. Before the mixing operation in FIG.
As shown in the partial cross-sectional view after the operation in (b), the moving member 4 and the vertically moving cam 43 are integrally molded to reduce the number of members, and the connecting pipe member 3 has an opening tightly gripping portion of the drug container 1.
By providing 32, the drug container cover 13 can be omitted, and the assembly can be performed by using only three members.

Embodiment 3. Before the mixing operation in FIG.
As shown in the exploded view of the outer cylinder portion in (b), the covering fixing material 5 which can be developed to the left and right is provided on the outer side of the connecting pipe material portion, and the members are assembled,
It can also be used for dismantling waste material processing.

[0013]

EFFECTS OF THE INVENTION The present invention uses a small number of members and is not only easy to assemble and cost-saving, but it is also possible to unplug and rupture the diaphragm by a single aseptic operation, which increases the flow rate at the time of mixing and facilitates mixing. Completely easy and eliminates contamination of chemicals due to mixing of plug material powder etc. due to perforation of the stopper during mixing, and also the difficulty of separate disposal due to integration of plastic, glass, metal, etc. It is a resolved new invention.
