Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention belongs to the technical field of an infusion container for infusion.

[0002]

2. Description of the Related Art A container body made of a flexible resin film material is provided by a weak heat seal or the like, having a suspension means at an upper end, an elastic stopper at a lower end through which a drip needle and a ventilation needle can be pierced. The partitioning means is divided into a plurality of chambers by the partitioning means having easy peelability, and the container body is pressed from the outside at the time of use, or the resin film constituting the container body is pulled in the separating direction, thereby facilitating the partitioning means. There is known an infusion container for intravenous drip injection, which is peeled off to allow communication between the two chambers to dissolve the drug. (For example, Japanese Patent Publication No. 6-265
No. 63, JP-A-1-240469, JP-A-2-24069

[0003]

In such a conventional infusion container for drip injection, the container main body is divided into a plurality of chambers such as a drug chamber and a solution chamber by a partition means having easy peelability. ing. The partition means constituting this compartment is constituted by a heat-sealing part which is weaker than other heat-sealing parts by changing the heat-sealing temperature of the resin films. In general, resin films have thickness variations, and when multiple layers are used, the thickness of each layer varies.Therefore, the welding temperature conditions in the weak heat sealing state resulting from these variations vary from resin film lot to lot. However, even in the same lot, these thickness variations occur in the portion of the wound resin film material. Further, in order to allow the partitioning means having easy peelability to be separated and communicated with a certain pressing force, it is very complicated to control the welding pressure and temperature of the partitioning means, in particular, the weak heat sealing portion, and the medicine and the solution As a means of processing containers that guarantees long-term stable storage against, it is extremely unstable without taking any other auxiliary means.

As described above, the formation of the partition wall means, that is, the formation of the weak heat seal portion, is inadvertently peeled off, which requires great care during manufacture. In addition, when the weak heat seal portion has strong adhesion, If it is not easily peeled off due to the pressing or pulling-off operation during use, or if the adhesion is weak, it may be peeled off unintentionally, which may lead to an accident that the infusion container for infusion may become unusable.

[0005] An object of the present invention is to provide an infusion container for infusion by drip injection, which can ensure long-term preservation of a drug and a dissolution solution by a simple structure, improve the dissolution efficiency of the drug, and establish the easiness of production. To provide.

[0006]

The object of the present invention is to provide a suspension means at the upper end and a liquid discharge means having a resilient stopper at the lower end through which a drip needle and a ventilation needle can be pierced. An easily-openable drug container enclosing a drug is accommodated inside a dissolving liquid container made of a flexible resin material or the like. On the other hand, foreign substances such as fragments generated by at least the drug container opening operation are contained in the liquid discharging means. This is achieved by providing a filtering means for removing the water.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway front view, and FIG. 2 is a cross-sectional view of a drug container as a PTP package.

Referring to FIG. 1, the details of the infusion container of the present invention will be described. 1 is a flexible 2 having a suspension hole 2 at the upper end.
Heat-sealing 1b single-layer or composite resin film 1a
A rubber stopper 3 through which a drip injection needle (not shown) and a ventilation needle (not shown) can be pierced at the lower end of the dissolving solution container 1 in a liquid-tight manner at the lower end opening. The discharged liquid 4 having a cylindrical structure is heat-welded 1c in a liquid-tight manner. In the dissolving solution container 1, a unit or a plurality of highly airtight drug containers 5 having an easy-to-open structure such as easy crushability, easy rupture, and easy peeling, in which a drug is sealed, are contained. .
Further, as the medicine container 5, a PTP package 5a can be used as shown in FIG. On the other hand, a filter member 6 is provided at the upper end of the ejected liquid 4 for removing foreign substances such as fragments generated when the medicine container 5 is crushed, broken or peeled off by an external pressure or an impact action. The filter member 6 can be provided with a sterilizing or sterilizing function by filtering bacteria or the like. The solution 1
May have a plastic bottle structure. The drug may be in any form such as powder, tablet, liquid and the like.

[0009]

[Explanation of handling] When injecting a drip into a patient, the dissolving solution container 1 is appropriately placed on a table or the like, and in this state, the drug container 5 is pressed or hit from above the dissolving solution container 1, and the The container 5 is crushed or broken or the heat seal is peeled off, and the drug solution obtained by sufficiently dissolving the drug in the dissolving solution is infused by a conventional method. At this time, foreign substances such as fragments generated by destruction, breakage, or peeling of the drug container 5 are completely removed by the filter member 6, and only the effective drug component is instilled into a human body or the like.

[0010]

According to the configuration of the present invention as described above,
The following effects can be obtained. (A) Since the drug container is freely stored in the solution container, the production and structure can be made much easier and simpler than in the prior art in which the compartment is separated by an easily peelable heat seal partition. Assurance of long-term stable storage of medicines and solutions is obtained. (B) Foreign matter such as fragments generated by destruction, rupture or peeling of the drug container can be completely removed by the filter member, and there is no fear that foreign matter is injected into the human body.
