Description

Technical Field

[0001] This invention relates to a pressurized bag.

Background Art

[0002] Patients who cannot obtain nutrition from meals through the oral cavity ingest a fluid substance containing nutritional agents, liquid foods, or drugs, etc. through enteral nutrition. In enteral nutrition, a flexible sheet is formed into a bag-shaped container (sometimes called a "pouch" or "laminate pack") by bonding, and the fluid substance filled in it is sent into the patient's body through a flexible catheter (generally called an "enteral nutrition catheter"). FIG. 9 shows a pressurized bag 601 described in Patent Document 1. The overall configuration is such that a pressurized chamber 615 is provided between an outer sheet 630 and an inner sheet 620. The inner sheet 620 is bonded to the outer sheet 630, and the end of the outer sheet 630 is joined at an outer-outer sheet joining region 642. When a bag-shaped container 650 containing a nutritional agent or the like is placed inside the pressurized bag 601 and a fluid such as air is introduced into the pressurized chamber 615 through a communication pipe 617 to apply pressure, a force is applied in the direction indicated by the arrow in FIG. 9, causing the bag-shaped container 650 to be compressed and pushed out from the bag-shaped container 650 through a tube and introduced into the patient's body.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When air or the like is introduced into the pressure chamber 615 and the pressure chamber 615 expands, a force is applied in the direction of the arrow in the lower cross-sectional view of FIG. 9, so that the bag-shaped container 650 is compressed. Forces are applied in the vertical direction of the pressure chamber 615 and also from the right direction, but no force is applied from the right direction on the side of the outer-outer sheet joining region 642 on the left side. The reason is that the outer-outer sheet joining region 642 exists in the form shown in FIG. 9, the rigidity per unit area of the outer-outer sheet joining region 642 is large, and the pressure chamber 615 does not exist at the left end either. As a result, due to such a structure, the bag-shaped container 650 is not partially pressurized, and there is a problem that nutrients or the like inside the bag-shaped container 650 remain in the bag-shaped container 650. The present invention has been made in view of such a point, and an object thereof is to provide a pressure bag capable of introducing more nutrients or the like inside the bag-shaped container into the patient's body.

For example, the bonding method of the first sheet 110 of the present invention (1) is described as "bonding the front and back surfaces of both ends of the first sheet in the vertical direction to form an outer cylindrical body", and the bonding method of the first-sheet vertical joint region 111 is to bond the "front and back surfaces" as shown in the figure. Different from the outer-outer sheet joint region 642 in Fig. 9, by performing this bonding method, a pressure bag can be provided that can introduce more nutrients and the like inside the bag-shaped container into the patient's body. Different from the outer-outer sheet joint region 642 in Fig. 9, by performing this bonding method, a pressure bag can be provided that can introduce more nutrients and the like inside the bag-shaped container into the patient's body. can be provided.

[0035] Fig. 7 shows an external photograph of the pressure bag 100 and the bag-shaped container 150 of Example 1. The bag-shaped container 150 is a dummy. The pressure bag 100 includes an outer bottomed cylindrical body 117 and a first sheet and a first sheet suspension part 113 having a suspension hole 114 for suspension.

[0036] FIG. 8 shows how the inner surface of the inner member 1 27 deforms when air or the like is introduced into the pressure chamber 130 to expand the pressure chamber 130. The inner surface of the inner member 127 deforms like the dotted line in the figure, and a force is applied from the arrow direction (all directions), pressing the bag-shaped container 150. The bag-shaped container 150 is housed inside the inner member 127 of the pressure bag 100 and is not visible from above.

Industrial Applicability

[0037] As described above, when the pressure bag of the present invention is used, it is possible to provide a pressure bag capable of introducing more nutrient agents or the like inside the bag-shaped container into the patient's body.
