Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an infusion bag. More specifically, glucose solution and amino acid solution can be stored separately.
The present invention relates to an infusion bag that allows the two infusion solutions to be mixed simply and aseptically prior to infusion.

<Conventional technology> In recent years, technological advances in high-calorie infusions and artificial intestinal tubes have been remarkable, and they are now being widely adopted to support the lives of many patients.However, in order to avoid deterioration of the infusions administered to patients, , multiple infusion solutions such as glucose solution and amino acid solution are stored separately in bottles,
Before use, the medicinal solution in each bottle is transferred and mixed into one bottle or bag using an infusion set or the like, or the two bottles are communicated with each other through a connecting tube with liquid guide needles at both ends. I was given an infusion.

<Problems to be solved by the invention> However, the above-mentioned method of transferring and mixing infusions into one bottle or bag requires multiple bottles containing infusions to be mixed, bottles or bags for mixing, and infusion sets, etc. This problem not only requires a large number of containers and equipment, but also requires extremely careful handling in order to carry out the transfer and mixing operations in an aseptic manner.

In addition, the above-mentioned method of infusing the two bottles in fluid communication does not allow the two solutions to mix completely, especially when infusing glucose and amino acid solutions together, which are poorly absorbed in the body unless they are thoroughly mixed. However, there was a drawback that the glucose solution, which is a hypertonic solution, was injected first, and the amino acid solution was injected later, resulting in poor absorption of the medicinal solution into the body, which was a problem.

This idea was created in view of the above problems.
The purpose is to provide an economical infusion bag that can separately store a glucose solution and an amino acid solution and easily mix the two solutions in an aseptic manner.

<Means for solving the problems> That is, the present invention is a flexible bag having two large and small chambers that are liquid-tightly defined for independently accommodating an amino acid solution and a glucose solution, The volume of the lower chamber is large enough to accommodate the total amount of the amino acid solution and glucose solution contained in the two chambers, and the partition band between the two chambers is provided at an angle, and the partition An infusion bag, wherein a flexible tube communicating the two chambers is exposed outside the bag at the inclined lower end of the band, and a clamping means for closing the flow path of the tube is disposed on the flexible tube. It is.

<Function> Since the infusion bag of the present invention has two compartments that are fluid-tightly partitioned, a glucose solution and an amino acid solution can be separated and stored separately in one bag.

In addition, the volume of the lower chamber is large enough to accommodate the total amount of medicinal solution contained in these two chambers,
and the partition band between the two rooms is provided at an angle,
A flexible tube that communicates the two chambers is provided at the inclined lower end of this partition band, so if the infusion bag is hung on a hanger or the like and the clamp means of the partition band is released, the drug solution in the upper chamber will naturally flow. The entire amount of liquid can be transferred to the lower chamber, and therefore, by pressing or shaking from the outside, it is possible to easily and aseptically mix the drug solution.

Furthermore, since the flexible tube that communicates the two chambers is exposed outside the bag, it is possible to reliably open and close the flow path, and therefore a clamp can be used to close the tube during transportation of the infusion bag. There is no way out.

<Example> Next, an example of the present invention will be described based on the drawings.

FIG. 1 is a plan view of an infusion bag according to one embodiment of the present invention, and FIG. 2 is a plan view of another embodiment.

As shown in FIG. 1, the infusion bag 1 of the present invention is constructed entirely of a flexible material such as vinyl chloride, and is connected to an upper chamber 4 and a lower chamber by a partitioning band 2 by means such as welding. It is divided into two rooms, room 5.
The partition band portion 2 is provided in an inclined manner as shown in the figure.

A connecting tube 3 is exposed outside the infusion bag 1 from the sloping lower end of the partition band 2 and communicates the upper and lower chambers in close proximity like a bridge. A clamp means 10 of a known structure such as a clamp with a tapered groove or a roller clamp is disposed, and the upper chamber 4 has an introduction tube 6 for introducing a small amount of chemical solution, and the lower chamber 5 has an introduction tube 7 for introducing a large amount of drug solution and a tube for introducing a mixed drug solution. A port 8 of known structure is arranged.

The connecting tube 3 has a U-shaped curved tube sandwiched between the side edges of two flexible sheets constituting the infusion bag 1, and the tube 3 together with the side edges of the sheets and the partition band 2 They can be easily arranged by welding them in such a way that they sandwich the partition band part 2.

In order to independently fill an amino acid solution and a glucose solution into an infusion bag, for example, when a small amount of an amino acid solution is used as a medicinal solution, the connecting tube 3 is connected to the clamping means 1.
0, a specified amount of amino acid solution is supplied from the liquid guide tube 6 to the upper chamber 4, and a specified amount of glucose solution is supplied from the liquid guide tube 7 to the lower chamber 5, at a position close to the main body of the infusion bag. What is necessary is just to melt-cut each of the liquid guide tubes 6 and 7.

Since the infusion bag of the present invention supplies the amino acid solution in the upper chamber 4 to the lower chamber 5 and mixes it with the glucose solution prior to infusion, the upper chamber 4 may be completely filled, but the lower chamber 5 is It must be incompletely filled so that the amino acid solution in chamber 4 can also be accommodated and can be completely mixed with the glucose solution in lower chamber 5. Therefore, the volume of the lower chamber is formed to be large enough to accommodate the total amount of prescribed amounts of amino acid solution and glucose solution.

The infusion bag 1 filled as described above is shipped after being sterilized by means such as an autoclave, and before use, the clamping means 10 is released to connect the upper and lower chambers, and the amino acid solution in the upper chamber 4 is released. Transfer into the lower chamber 5, close the connecting tube 3 with the clamp means 10 if necessary, mix the amino acid solution and the glucose solution by a method such as shaking, and connect the port 8 of the lower chamber 5 with the normal type. An infusion set, etc. is connected to perform infusion.

In Fig. 2, a connecting tube 3 is arranged at the bottom of a V-shaped partition band 2 of an infusion bag. It is exposed to the outside, and a clamping means 10 is arranged in this exposed part.
In this arrangement, the connecting tube 3 does not protrude from the side edge of the infusion bag, so it has the advantage of saving space.

In order to arrange the connecting tube, a notch 9 is created at a predetermined position on the plane of the infusion bag, passing through the two sheets that make up the infusion bag. This can be easily done by inserting the tube into both the upper and lower chambers through the notch 9 and fusing the periphery of the notch 9 together with the connecting tube.

<Effects> As is clear from the above explanation, the infusion bag of the present invention has the following advantages.

(1) The amino acid solution and glucose solution can be contained independently in a single bag, and the two solutions can be easily mixed in a sterile manner at the time of use.

(2) It is easy and economical to manufacture.

(3) Since the clamp means can be operated directly outside the infusion bag, the flow path can be opened and closed reliably.
