[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an infusion bag, and more particularly to an infusion bag used when performing drip in a hospital or the like.

[0002]

[Prior Art]

 Conventionally, in a hospital or the like, when an infusion solution such as a glucose solution, an amino acid solution, or a Ringer's solution is administered to a living body, a vial or a bottle has been used as a container for storing the infusion solution. Infusion bags made of flexible plastic are widely used because they do not require air needles, can perform infusion mixing operations aseptically, and require a small space for empty container disposal. There is.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned infusion bag is made of flexible plastic and has poor self-sustainability, it is difficult to mix-inject the infusion solution and perform a needle stick operation when using it. There was a problem of taking. In order to solve this problem, a stand that holds the infusion bag in an upright state (see Japanese Patent Publication No. 2-36462) and an infusion bag that has a bottom plate that also serves as a lifting tool (see Japanese Utility Model Publication No. 57-21344). , A pouch type infusion bag (see Japanese Utility Model Laid-Open No. 2-9811, JP-A-60-116356, JP-A-60-153865, JP-A-60-225559, etc.), an infusion with a concave bottom. Bags (see Japanese Utility Model Publication No. 1-140954) and the like have been proposed.

However, when using the above-mentioned stand, it is necessary to attach the infusion bag to the stand before performing an operation such as needle stick and remove it after the operation, which is troublesome. In the case of the infusion bag described above, the above-mentioned problem cannot be solved at all because the body of the infusion bag lacks independence. The infusion bag cannot be used when administering trace drugs such as vitamins, because the infusion solution tends to remain in the bag at the end of infusion administration. Further, JP-A-60-116356 and JP-A-60-153865 disclose standing pouches for infusion, which are used for work such as mixed injection and needle stick in a state of being self-supporting on a desk or the like. Is something that cannot be done. The ones are not self-reliant and are unstable in the standing state. In addition, it is difficult to mold, and the strength of the bottom is not sufficient. As described above, none of the above infusion bags has yet to solve the above problems.

The present invention has been made in order to solve the above-mentioned problems, and is highly self-sustaining, allowing the infusion of mixed fluids and the needle stick operation to be easily performed, and the space required for each of the above operations. The purpose of the present invention is to provide an infusion bag with a small waste space.

[0006]

[Means for Solving the Problems]

 An infusion bag according to the present invention for solving the above-mentioned problems is an infusion bag made of a synthetic resin sheet or film, and having an infusion container for accommodating an infusion, which has heat-sealed side edges, It has a bottom part of the infusion solution storage part that expands in the front-rear direction when the infusion solution is stored, and a skirt part extending from the front and rear edges of the bottom part in the direction opposite to the infusion port side. It is characterized in that the film is formed by folding it into a W shape.

[0007]

[Action]

 According to the liquid transfusing bag having the above structure, the skirt portion can be made to stand on its own in a state of being in contact with a mounting place such as a desk. In addition, the heat-sealed side edges enhance the independence of the infusion solution bag, and when the infusion solution is stored in the infusion solution storage part, the bottom of the infusion solution storage part expands in the front-back direction. Since the space between the skirts formed at the front and rear of the bottom becomes large, this infusion bag can be placed on a desk or the like in a stable state.

Further, in this infusion solution bag, since the infusion solution storage part is made of a synthetic resin sheet or film, when the infusion solution administration ends and there is no more infusion solution in the infusion solution storage part, the infusion solution storage part is flattened. Become.

【Example】

 Hereinafter, the present invention will be described in more detail based on examples. FIG. 1 is a perspective view showing an embodiment of an infusion bag A according to the present invention. The infusion bag A is formed of a transparent transparent synthetic resin sheet, has an infusion solution storage portion 1 for storing the infusion fluid B, and a side edge portion 13 is heat-sealed.

An infusion port 21 is provided at an upper end 11 of the infusion container 1, and a boat core 2 for an infusion port having a size smaller than the bottom 12 of the infusion container 1 is fixed by heat sealing. In addition, front and rear skirts 31 and 32 extending in the direction opposite to the infusion port 21 are formed at the front and rear edges of the bottom 12 of the infusion storage unit 1. The front and rear skirts 31 and 32 are provided with the infusion bag A. A hanging hole 33 for hanging is provided.

As shown in FIGS. 2 (a) and 2 (b), the bottom portion 12 and the front and rear skirt portions 31 and 32 are formed by folding the synthetic resin sheet 1a into a W-shape so that the mountain-folded portions are cured. It is formed by inserting the tool C and heat-sealing the peripheral edge 20a of the portion 12a which becomes the bottom portion 12 and the peripheral edge 20b of the portion 3a which becomes the front and rear skirt portions 31, 32. Therefore, when the infusion solution B is filled in the infusion solution storage portion 1, the bottom portion 12 expands into a boat shape due to the weight of the infusion solution B, and the front and rear skirt portions 31 and 32 are separated from each other.

When the infusion bag A is made to stand on a desk or the like, the lower ends 34 of the skirt portions 31 and 32 come into contact with the surface of the desk or the like. The infusion bag A is provided with high self-sustainability by the heat-sealed side edge portion 13 and the peripheral edge 20b. Further, in the state where the skirt portion 3 is formed of a double-layered synthetic resin sheet and when the infusion solution storage portion 1 is filled with the infusion solution B, the skirt portion 3 is provided between the front skirt portion 31 and the rear skirt portion 32. Since they are far apart, they can be stable and independent.

Further, since the bottom portion 12 of the infusion solution storage portion 1 is larger than the boat mouth core 2 for infusion fluid portion arranged at the upper end 11 of the infusion solution storage portion 1, it is possible to make the vessel stand in a particularly stable manner and to be self-supporting. Work such as mixed injection and needle stick can be performed easily and surely in the closed state. In addition, by storing in an independent state, the storage space can be reduced, while when the infusion solution B in the infusion solution storage portion 1 is used up, the bottom 12 is closed and the entire infusion bag A is flat. And the occupied space becomes smaller.

When manufacturing this infusion bag A, as shown in FIGS. 2 (a) and 2 (b), a long synthetic resin sheet or film is bent in the middle of a W shape. Then, as described above, the peripheral edge 20a of the portion 12a which becomes the bottom portion 12 and the peripheral edge 20b of the portion 3a which becomes the front and rear skirt portions 31, 32 are heat-sealed to form the front and rear skirt portions 31, 32 and the bottom portion 12, and The side edge portion 13 is also heat-sealed to form the bag 10 (see FIG. 3).

Then, the boat core 2 for an infusion port is inserted into the opening 10 a of the bag 10 and heat-sealed to form the infusion container 1. Also, a hanging hole 33 is made in the front and rear skirt portions 31, 32 (see FIG. 4). Then, the infusion solution B is filled in the infusion solution storage portion 1 and the cap 22 is heat-sealed to the infusion port 21 (see FIG. 1).

Examples of the sheet or film used for producing the infusion bag A include a single layer or a multi-layered sheet made of polyethylene, polypropylene or the like. The vessel core 2 for the infusion port may be made of polyethylene, polypropylene or the like, and preferably made of the same material as the sheet or film.

The infusion bag of the present invention is not limited to the above embodiment. For example, as in the infusion bag A shown in FIG. 5, instead of opening the hanging hole 33 in the skirt portion 3, a small piece 4 in which the hanging hole 33 is formed is attached to the bottom portion 12 of the infusion container 1. Good. Further, as in the infusion solution bag A shown in FIG. 6, a synthetic resin plate 5 having an appropriate thickness may be bonded to the side edge portion 13 and a part of the upper end 11 of the infusion solution housing portion 1. Since the rigidity of the infusion bag A is particularly enhanced by the synthetic resin plate 5, it is possible to perform operations such as needle stick in a self-standing state.
