Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nutrient container, and more particularly to a nutrient container that can be used as it is at a medical site for administration of a nutrient.

[0002]

2. Description of the Prior Art Patients with insufficient or incapacitated swallowing due to cerebral / neurological disorders or anesthesia treatment are offered esophagus,
Nutrition or water is directly administered to the stomach or intestine (hereinafter referred to as
Enteral administration).

[0003] Enteral administration of nutrients may cause the concentration and dosage of the nutrients to be incompatible with the patient's physical condition immediately after the start of administration, in which case diarrhea, fluctuations in blood pressure and other symptoms may occur. , While observing the patient's condition,
Adjust the concentration and dosage, and administer the drug, if necessary. In general, supplementation of water, salt and the like is performed after administration of the nutrient.

[0004] The administration and supplementation of the above-mentioned nutrients, water and salts, etc. have been carried out by adjusting the concentration of the nutrients according to the disease state of the patient and using an irrigator through a administration tube and a catheter. In order to stabilize quality, save labor at medical sites, and ensure good hygiene, they are supplied packed in retort pouch-shaped containers.

[0005] In the above-mentioned nutrient container, the supply of water and salt or the administration of the drug cannot be freely performed as in the case of Illigarter. Dilution and drug injection had to be performed, which was an obstacle to labor saving at medical sites.

[0006] In order to solve the above problem, Japanese Patent Application No. Hei 8-3
No. 49435 (Japanese Patent Application Laid-Open No. 10-179691) states, "In a container formed by heat-sealing the periphery of a film having a heat-adhesive synthetic resin layer in the inner layer, an extraction member is attached to one side of the container and the extraction is performed. A tube for enteral nutritional supplement comprising an injecting member having a lid member on a side edge at a position facing the side on which the member is mounted has been proposed.

[0007]

In the above-mentioned container for tube-feeding enteral nutrition, the injection member is provided at the side edge opposite to the side on which the extraction member is mounted. However, it is difficult to inject the diluent or the drug due to the small diameter of the injection member.In order to increase the diameter and facilitate the injection of the diluent or the drug, the cost of the container is increased, and However, there are problems such as increased bulk and increased transportation costs.

[0008] In view of the above problems, the present invention is a nutrient container, in which a diluent or a drug can be easily injected. Particularly, it is possible to adjust the concentration or inject the drug even during the administration of the nutrient, thereby reducing the cost of the container. It is an object of the present invention to provide a device which is reduced in volume and low in bulk and does not increase transportation cost.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is a container comprising a plastic film whose peripheral edge is fused to form a bag, an extraction port provided at a lower portion thereof, and an injection port provided at an upper portion thereof. A zipper is provided inside the vicinity of the upper edge fusion portion of the container, in which the convex groove is fitted with the concave groove.

According to the present invention configured as described above, in a state in which the fusion portion at the upper edge is cut open and the nutrient is administered, the zipper is opened so that the injection of the diluting liquid or the medicine becomes easy. Since it becomes easy to change the concentration or inject the drug during administration, labor saving at the medical site is greatly advanced.

Further, during administration of the nutrient, the zipper is closed to prevent foreign substances from entering and bacteria from entering, so that a good hygiene condition can be maintained. Cost reduction is also possible.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment. As shown in FIG. 3, a laminated resin film 3 composed of a thermally fusible resin layer 1 and a reinforcing resin layer 2 is used as a material. A zipper 8 is provided near the inside of the upper edge fusion portion 4 'of the container 5 with the periphery 1 fused inside (see FIG. 1).
The extraction port member 9 is heat-sealed to the lower corner of the
A through hole 10 for suspending the container 5 is provided at a diagonal corner of.

The extraction port member 9 comprises a main body portion 9a and a twist cutout portion 9b. When the nutrient is administered, the twisting cutout portion 9b is twisted and cut off at the constricted portion 14, and the main body portion 9 is cut off.
The connector 13 is screwed into the screw 11a, and the drip tube is connected.

The reason why the lower side of the container 5 is not heat-sealed is that
At the opening 15 for packing the nutrient, the nutrient is heat-sealed after being injected from the opening 15. Further, a dotted line drawn between the heat-sealed portion 4 ′ at the upper edge of the container 5 and the zipper 8 is a cut line, and a diluent or drug is injected into the nutrient when the nutrient is administered. At this time, this portion is cut off and the zipper 8 is opened to inject a diluent / drug or the like.

The thickness of the laminated resin film 3 is as follows.
Although not particularly limited, generally 30 to 15
The heat-fusible resin layer is made of a polyolefin-based resin having heat-fusibility such as polypropylene or polyethylene, and the reinforcing resin layer is made of biaxially stretched polyester, biaxially stretched polyamide, A material with relatively high mechanical strength, such as stretched polypropylene, is used.When a light-shielding property is required, an aluminum laminated film is used.When a gas barrier property is required, an inorganic vapor-deposited polyester film, an ethylene-vinyl alcohol copolymer are used. Is employed.

In the above embodiment, the laminated resin film 3 composed of the heat-fusible resin layer 1 and the reinforcing resin layer 2 is used. However, the laminated resin film 3 is not necessarily required to be a laminated film. Is also good.

Next, the manufacture of the nutrient administration container 5 will be described. First, the zipper 8 is held while the heat-fusible resin layer 1 of the two laminated resin films 3 is set inside (to face each other).
After heat-sealing, the upper edge and both side edges are heat-sealed with a heating platen. Next, the extraction port member 9 is inserted between the two films having the oblique cut edges, and is heat-sealed with a heating platen so that the lower edge has an opening 15.
Obtained container 5 is obtained. The reason why the heat-sealed width of the upper edge leftward portion is increased is to reinforce the through hole 10 for suspending the container 5 on a stand (not shown).

A nutrient is filled with the lower opening 15 of the container 5 obtained as described above facing upward, and then the opening 15 is heat-sealed by a sealing device (not shown).

When a nutrient is administered using the nutrient container filled with the nutrient, the torsion cutout 9b is cut off with the extraction port member 9 facing upward, and the screw 11 of the main body 9a of the extraction port member 9 is cut off. The nutrient drip tube 12 is connected by screwing the connector 13 to the nut, and the container 5 is hung on a stand (not shown) using the through hole 10.

When injecting a diluting liquid or a medicine, the upper part of the container 5 is cut along a cutting line between the upper edge heat-sealing portion 4 'and the zipper 8, the zipper 8 is opened, and the diluting liquid or the medicine is poured. Inject and close the zipper 8 to prevent foreign matter and bacteria from entering. When supplementation of water, salt, or the like is necessary at the time when the administration of the nutrient is completed, the zipper 8 is opened, and physiological saline or the like can be injected into the container 5 so that supplementation can be performed continuously.

FIG. 2 shows a second embodiment in which an extraction port member 9 is attached to the center of the lower edge of the container 5, a through hole 10 for hanging the container is provided at the center of the upper edge, and the zipper 8 is provided in double. so,
The right side of the extraction port member 9 is not heat-fused but is an opening 15 for filling with a nutrient.

The manufacture of the container of this embodiment is basically the same as the manufacture of the first embodiment, and the only difference is that the heat-sealing position changes in accordance with the shape of the container.

[0023]

As described above, according to the present invention, the opening of the zipper facilitates the injection of the diluent and the drug, particularly the change of the concentration during the injection and the injection of the drug, thereby facilitating the injection in the medical field. Labor saving has become possible.

Further, by closing the zipper during the administration of the nutrient, it is possible to prevent the entry of foreign substances and the invasion of bacteria and to maintain a good hygiene condition.
Being able to reduce the bulk has made it possible to reduce transportation costs.
