DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a nutritional supplement bag according to the present invention will be described in detail with reference to the preferred embodiments shown in the accompanying drawings.

FIG. 1 is a partial longitudinal sectional view showing an embodiment of the nutritional supplement bag of the present invention, and FIGS. 2 to 7 are partial sectional views showing a connected state of the nutritional supplement bag shown in FIG.

As shown in these figures, a nutritional supplement bag 1 of the present invention is made of a soft material and has a bag-like bag body 2 capable of storing a nutritional supplement (liquid), and one end of the bag main body 2. A discharge port forming member 6 attached to the discharge port 3 provided in the section, the discharge port forming member 6 is capable of communicating with an internal flow path by breaking, and a communication mechanism 7 as described later. And a connecting portion 8 to which a predetermined pipe can be connected.

Hereinafter, each of these components will be sequentially described. The bag body 2 has a bag shape made of a soft material (for example, a resin material), and is a container for containing a nutrient.

The bag body 2 is made of, for example, a soft resin material. This facilitates the opening operation of the communication mechanism 7 described later from the outside of the bag body 2.

The bag body 2 is formed by laminating two flexible resin sheet materials and sealing the periphery by fusing (for example, heat fusing or high frequency fusing) or bonding to form a bag. Alternatively, a thermoplastic resin material is formed into a bag shape by cylindrical extrusion molding, and both ends thereof are fused or bonded in the same manner as in the case of the sheet material.

As the soft resin material constituting such a bag body 2, for example, polyethylene, polypropylene, polybutadiene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), polyethylene terephthalate (PET), polybutylene terephthalate ( Polyester such as PBT), flexible polyvinyl chloride, polyvinylidene chloride, silicone, polyurethane,
Examples include various thermoplastic elastomers such as polyamide elastomers and those obtained by arbitrarily combining these (blend resins, polymer alloys, laminates, etc.).

Further, in order to suppress deterioration and decomposition of nutrient components with time and maintain quality, aluminum foil or the like is used to impart oxygen barrier properties or light-shielding properties to the surface of the sheet material composed of the above-mentioned materials. It is also possible to form a thin film such as a vapor-deposited film made of an oxide such as titanium oxide, aluminum oxide or silicon oxide in order to further laminate the above film or to provide oxygen barrier properties.

Alternatively, in order to improve the strength of the bag body 2 and ensure drop resistance and retort resistance, the sheet material is formed by laminating a plurality of layers (reinforcing layers) of the same or different materials. Is also good.

For example, one side of the bag body 2 is composed of a laminate of unstretched polypropylene and polyester from the inside, and the other side is formed of unstretched polypropylene and stretched nylon.
A bag body made of a laminate of aluminum foil and polyester is exemplified.

On the inside surrounded by the seal portion 4, a storage portion 5 for storing a nutrient, which is the content of the nutrient bag 1, is formed.

The nutrient stored in the storage section 5 includes, for example, a semi-digestive nutrient, a digestive nutrient, and a component nutrient (E
D), liquid food, mixer food and the like.

Further, a suspending portion 9 having a hole or the like for suspending the nutritional supplement bag 1 on a stand is provided at a portion of the seal portion 4 facing the later-described discharge port 3 in the longitudinal direction. Good.

It is preferable that the housing section 5 has a tapered section 10 in which the width of the bag body 2 gradually decreases toward the outlet 3. With such a structure, the nutrient can be efficiently discharged from the storage unit 5, and the nutrient does not remain in the storage unit 5 even when the nutrient bag 1 is suspended, so that the nutrient can be efficiently processed. A nutrient such as tube feeding can be supplied.

A discharge port 3 is provided at one end of the bag body 2, and is provided at a substantially central portion in the width direction of the seal portion 4 in this embodiment. The nutrient can be discharged through the discharge port 3.

The outlet 3 is provided with an outlet forming member 6. The discharge port forming member 6 has a communication mechanism 7 capable of connecting the internal flow path by breaking, a connecting portion 8 capable of connecting a pipe, and a fixing portion 62 located therebetween.

The outlet 3 is sealed by the outlet forming member 6 unless an opening operation is performed, and the nutrient bag 1 can be connected to the intubation tube or the extension tube connected thereto. Can form an administration route for tube feeding.

As shown in FIG. 1, the discharge port forming member 6 sandwiches the fixing portion 62 between sheet materials near the discharge port 3 and is attached to the discharge port 3 in a liquid-tight manner by fusing or bonding. ing.

The discharge port forming member 6 is provided with a hole communicating from at least the break portion 72 of the communication mechanism 7 to the opening 821 of the connection portion 8 to form a flow path 711. This allows nutrients to be distributed.

Further, it is preferable that the discharge port forming member 6 cannot be communicated by puncturing with a bottle needle or a puncturing needle. With such a configuration, it is possible to prevent the infusion line from being erroneously connected to the nutritional supplement bag 1, and to prevent a medical accident from occurring.

That is, the infusion line 2 as shown in FIG.
0 is a bottle needle 31 for piercing a drug solution bottle or bag at one end and introducing an infusion solution into the line 30.
The other end has a connector 32 for connecting to the downstream line 40.

On the other hand, the downstream line 40 has a puncture needle 42 such as a venous needle at one end, and a connector 43 for connecting to the connector 32 of the upstream line 30 at the other end.

For example, a bottle needle 31 provided on the upstream side 30
Is inserted through the opening 821 of the discharge port forming member 6 and an attempt is made to connect, only the tip of the bottle needle 31 enters the lumen of the connecting portion 8 or the like, and an effective connection with the connecting portion 8 cannot be performed. The flow path 711 cannot be made conductive.

On the other hand, even if the connector 32 of the upstream line 30 can be connected to the connection portion 8, the bottle needle 31 on the opposite side can be connected.
The connector 43 of the downstream line 40 including the puncture needle 42
Since the infusion line cannot be connected, the infusion line 20 is not configured, and it is unlikely that a nutritional supplement is erroneously injected intravenously.

Further, even if an attempt is made to connect the puncture needle 42 provided at one end of the downstream line 40 to the connection portion 8, the puncture needle 42 is connected to the connection portion 8, the fixing portion 62, as in the case of the bottle needle 31. It only penetrates the lumen of the tube 71. Further, even if the tip of the puncture needle 42 longer than the bottle needle 31 abuts on the tip 73, the outlet forming member 6 is made of a hard material as described later, so that the tip 73 is pierced. Can not.

On the other hand, the connector 43 of the downstream line 40
Can be connected to the connector 32, but cannot be connected to the connector 8 because it has the same shape. Therefore, the downstream line 40 is directly connected to the nutritional supplement bag 1,
Infusion of nutrients can never happen.

The outlet forming member 6 is preferably made of a hard material. Thereby, the opening operation of the communication mechanism 7 can be performed more easily. Further, as described above, it is possible to prevent the puncture with a puncture needle or the like.

Examples of such a hard material include hard polyvinyl chloride, polyethylene, polypropylene, polyolefin such as polybutadiene, polystyrene, and the like.
Poly- (4-methylpentene-1), polycarbonate, ABS resin, acrylic resin, polymethyl methacrylate (PMMA), polyacetal, polyarylate, polyacrylonitrile, polyvinylidene fluoride,
Ionomer, acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate (PET),
Examples include polyesters such as polybutylene terephthalate (PTB), various resins such as butadiene-styrene copolymers, aromatic and aliphatic polyamides, and any combination of these resins.

As shown in FIG. 1, the communication mechanism 7
2 comprises a tube 71 provided so as to protrude into the housing portion 5 from above the hole provided at a substantially central portion, and a break portion 72 provided at the base end of the tube 71. .

The distal end 73 of the tube 71 is closed.
As a result, the flow channel 711 is sealed unless the opening operation is performed, so that the nutrient in the storage unit 5 does not leak out of the bag, and bacteria, air, and the like from the outside into the storage unit 5 are prevented. Intrusion can be prevented.

Further, at the base end of the tube 71, a broken portion 72 formed of a thin brittle portion of the tube 71 is provided. Thereby, when the opening operation is performed by applying a force to the tube body 71, the tube body 71 is surely broken at the break portion 72, so that the flow path of the nutrient can be easily formed.

It is preferable that the fragments generated after breaking the communication mechanism 7 float in the nutrient. As a result, the broken fragments settle near the fixing portion 62, thereby blocking the flow path,
It is possible to avoid hindering the discharge of nutrients.

In order to form broken fragments floating in the nutrient, a method using a material having a specific gravity lower than that of the nutrient in the storage portion 5 or a method of providing a hollow portion in a part of the broken fragments can be used. .

On the surface of the fixing portion 62 opposite to the surface on which the communication mechanism 7 is provided, there is provided a connecting portion 8 to which a pipe can be connected.

The connecting portion 8 of the present embodiment is a first connecting portion 81 that can be fitted into the tube 16 having elasticity or flexibility.
And a second connecting portion 82 capable of connecting the connector 12 in a liquid-tight manner.
And With such a configuration, a connecting member attachable to a conventionally used tube feeding tube, for example, a tube for intubation provided with a rubber tube (or a vinyl chloride tube or the like) or a connector with a luer lock, or the like. Since the extension tube connected to this can be used as it is, the structure of the connection portion is not restricted by a specific structure, and is excellent in versatility.

Further, the connecting portion 8 is connected to the first connecting portion 8.
By providing both the first and second connection portions 82, the connection member can be selected from any of the above-described rubber tube and the like and a connector with a luer lock, and further excellent in versatility. Can be.

As shown in FIGS. 5 to 7, the first connecting portion 81 has a shoulder portion 812 having a tapered portion whose width gradually decreases from the enlarged diameter portion 813 toward the fixing portion 62, and a downstream portion of the shoulder portion 812. The cylindrical body 80 is composed of a body 811 having a tapered portion whose width gradually increases from the opening 821 to the enlarged diameter portion 813.

When the rubber tube 14 is fitted on the first connecting portion 81, the width of the body 811 gradually increases from the opening 821 toward the enlarged diameter portion 813. The rubber tube 14 is deformed according to the shape of 811, and is brought into close contact with the tapered portion of the body 811 by the restoring force of the rubber tube 14. When the rubber tube 14 is further fitted to the upstream side, the close contact force of the tube body is maximized at the enlarged diameter portion 813, and then, at the shoulder portion 812, the open end of the rubber tube 14 is gradually reduced in diameter to the original shape. I will do it.

For this reason, the rubber tube 14 is connected to the first connecting portion 81.
Since connection of the nutrient is suppressed, the connection is ensured, and leakage of nutrients from the connection portion and invasion of air and bacteria can be prevented.

The second connecting portion 82 has a flange 83 which can be engaged with the connector 12. Further, at least the lumen of the connection portion 8 near the opening 821 has a taper whose inner diameter gradually increases toward the flange 83.

The connector 12 has a double cylinder structure of an outer cylinder 121 and an inner cylinder 123 as shown in FIGS.
21 is rotatably mounted around the inner cylinder 123.

The inner wall surface of the outer cylinder 121 has a spiral thread 1
22 are provided, and have a structure capable of engaging with the flange 83.

The inner cylinder 123 has a taper whose diameter gradually increases from the distal end toward the proximal end. In this case, the inner cylinder 12
The taper 3 has substantially the same taper angle as the taper of the lumen of the connecting portion 8.

Thus, when connecting the connector 12, it is easy to insert the inner tube 123 into the opening 821, and when it is in the connected state, the outer peripheral surface of the inner tube 123 and the inner wall surface of the connecting portion 8 are separated. Due to the close contact, a liquid-tight connection is ensured, and leakage of nutrients from the connection portion and invasion of air and bacteria can be prevented.

For example, as shown in FIG.
Is attached to the second connecting portion 82 by inserting the inner cylinder 123 of the connector 12 from the opening 821 and connecting the outer cylinder 121 to the inner cylinder 1.
Rotate clockwise with respect to 23. Then, the outer cylinder 12
The inner cylinder 123 intrudes through the opening 821 in the axial direction because the screw thread 122 spirally provided on the inner wall surface of the inner cylinder 1 and the flange 83 are engaged.

When the inner cylinder 123 is firmly fitted into the opening 821, the connection operation is completed. At this time, since the flange 83 and the thread 122 are engaged with each other, the connector 12 is fixed, and the connector 12 is prevented from coming off.

The communication mechanism 7, the fixing portion 62 and the connecting portion 8 may be formed integrally or may be separate members, but are preferably formed of a hard material.

As a result, the opening operation of the communication mechanism 7 becomes easier, and the connection between the connecting portion 8 and the tube can be made more secure. Then, even if the user accidentally tries to connect with a puncture needle or the like, the needle is not pierced by the needle.

FIG. 8 is a longitudinal sectional view showing another embodiment of the nutritional supplement bag of the present invention. In the nutritional supplement bag of the present embodiment, the connection portion 8 is located inside the bag main body 2.

When performing tube feeding, the connecting portion 8 of the seal portion 4
A part of the bag body 2 is cut or peeled (peel-opened) by a notch 41 provided in the vicinity of the position where the connector 12 or the rubber tube 14 is exposed in the same manner as described above. Connect with etc.

In particular, in this embodiment, since the connecting portion 8 is accommodated in the bag main body 2 until it is necessary, the connecting portion 8 can be stored and transported in the nutritional supplement bag 1 or can be used for tube feeding. Adhesion of foreign substances, bacteria, and the like to the connection portion in the nutrition preparation stage can be suppressed, and the danger of bacterial contamination, decay, and the like of the nutrient can be further reduced.

Further, by providing the opening means such as the notch 41, the opening operation is facilitated, and the preparation and treatment of tube feeding can be performed quickly.

As described above, the nutritional supplement bag of the present invention has been described for each of the illustrated embodiments, but the present invention is not limited to these.

For example, the shape and structure of the communication mechanism are not limited to those having a pipe and a break as shown in the figure, and the communication method is not limited to the method using a break. Further, the shapes and the like of the first connection portion and the second connection portion are not limited to the illustrated embodiments.

[0076]

As described above, according to the nutritional supplement bag of the present invention, a medical accident can be prevented beforehand because it is not erroneously connected to the infusion line. In addition, since a special kit for connection is not required, versatility is excellent.

Further, when the connecting portion is housed inside the bag body, adverse effects such as adhesion of foreign matter, bacterial contamination of nutrients, and decay can be further reduced.
