Description

  The present invention relates to a container for containing a nutrient to be supplied directly to a patient's stomach or intestine through a fistula evacuated in the patient's abdomen to supplement the patient.

  Enteral nutrition has been used as a means of nutritional supplementation for patients who cannot be taken orally due to some kind of disorder or disease, such as consciousness disorder, dysphagia, and fire extinguisher disease. Enteral nutrition refers to a tube placed nasally in the stomach or duodenum, or a fistula inserted in a hole that spans the patient's abdominal and gastric or intestinal walls (gastric fistula, intestinal fistula) Through which the nutrient is administered. Conventionally, enteral nutrition has mainly used liquid nutrients, but in the case of liquid nutrients, the nutrients administered into the stomach regurgitate toward the esophagus (gastroesophageal reflux). There is concern that it may cause reflux esophagitis and swallowing pneumonia. As a method for preventing the gastroesophageal reflux, a semi-solid or viscous nutrient is proposed (Patent Document 1: Japanese Patent Laid-Open No. 2004-26844, Patent Document 2: Japanese Patent Laid-Open No. 2004-217531).

Administration of these semi-solid or viscous nutrients (hereinafter gelled nutrients) is prepared in containers such as plastic syringes or dressing pots, or transferred to these containers, and the syringe The pushing action or dressing pot is pressed and supplied to the stomach or intestine via the fistula.

  By the way, in the method of administering the gelatinized nutrient using a plastic syringe, the capacity | capacitance of a plastic syringe is limited and there exists a subject that there is little quantity of the nutrient which can be administered at once. If the capacity of the plastic syringe is increased to accommodate a nutrient necessary for one administration, the plastic syringe becomes difficult to handle.

Moreover, in the method of putting a nutrient in a dressing pot and administering it, the dressing pot must be depressed at the time of administration, and there exists a subject that strong force is needed.
Furthermore, in the method of administration using a plastic syringe or dressing pot, the gelling nutrient must be prepared in a container such as a plastic syringe or dressing pot at the time of administration, or transferred to these containers. In other words, it takes time and the nutrients may be contaminated by microorganisms.

The present invention has been made based on such a background, and a main object of the present invention is to provide a container for a nutrient for supplying a fistula that allows an appropriate amount of the nutrient to be easily administered by a single administration. .
Another object of the present invention is to provide a container for a nutrient for supplying a fistula, which can perform gastrostomy directly through the fistula from the container itself containing the gelled nutrient. Furthermore, an object of the present invention is to provide a nutrient solution set for feeding a fistula that is suitable for distribution and storage and can be used as needed one by one when administration is required.

  The invention according to claim 1 is a container for containing a nutrient supplied to the stomach or intestine through a fistula, and a bag provided with a storage chamber in which the nutrient is stored, and a bag attached to the bag. The bag is deformed in response to an external force, whereby the nutrient contained in the storage chamber is discharged from the spout, and the deformed bag is not deformed even if the external force is removed. It is a container for a nutrient for supplying a fistula, characterized in that it is formed of a material that does not naturally recover its form.

The invention described in claim 2 is the container for nutrients for feeding a sputum according to claim 1, wherein the bag is formed by laminating sheets of a predetermined shape.
The invention according to claim 3 is characterized in that the spout has a tapered shape whose outer shape is narrowed toward the tip so that the spout protrudes from the bag and can be directly connected to the tub tube. It is a container for nutrients for the supply of tubules.

The invention according to claim 4 is an adapter for connecting the container according to claim 1 or 2 and the soot tube, and has a first connection port that can be connected to the spout at one end and the other end at the other end. It is an adapter characterized by having the 2nd connection port connectable with a soot pipe.
According to a fifth aspect of the present invention, the spout includes a spout body attached to a bag and a lid detachably fitted to the spout body, and the adapter has an upper first connection port instead of a recording lid. The adapter according to claim 4, wherein the adapter can be fitted to the spout body.

The invention according to claim 6 is a nutrient tube set for feeding a fistula that is supplied to the stomach or intestine through a fistula, a bag having a storage chamber in which a nutrient is stored, and a bag attached to the bag. And the nutrient is a gelling nutrient having a hardness of 2000-20000 N / m ² , and the bag is deformed in response to an external force, thereby being accommodated in the accommodation chamber. The deformed bag is formed of a material that does not naturally restore to its original shape even when external nutrients are removed from the spout, and the spout is composed of a spout body attached to the bag and a spout. An adapter for connecting the spout and the tub tube, and having a first connection port that can be fitted to the spout body instead of the lid. Can be connected to the pipe at the other end An adapter having a second connection port, together are fistula nutrient set for supply, characterized in that there is a 1 set.

  According to invention of Claim 1, the bag in which a nutrient is accommodated is formed with the material which deform | transforms according to external force, and does not restore naturally to the shape before a deformation | transformation even if external force is removed. Therefore, when supplying the nutrient contained in the bag (accommodating chamber) through the tub tube, if the bag is lightly pressurized, the stored nutrient can be easily supplied from the spout to the tub tube. In addition, the supplier (nurse) can adjust the feeding rate of the nutrient while watching the patient. For example, when the supply is interrupted for a short time, the pressure applied to the bag with fingers is relaxed or released. In that case, since the bag does not swell to the original state, the nutrient supplied from the bag to the tub tube does not flow back into the bag.

The bag is easily deformed by pressurization with fingers and the deformation is not naturally restored, so that the nutrient can be supplied smoothly and without difficulty.
Further, if the bag (accommodating chamber) has a desired capacity, nutrients necessary for one administration can be accommodated, so that a so-called single-use container can be obtained, and hygiene reliability is improved.
According to invention of Claim 2, a bag can be formed by bonding a sheet | seat. As this sheet, it is preferable to use a laminated sheet of resin, aluminum or the like.

In the invention of claim 3, the outer shape of the spout has a tapered shape that narrows toward the tip. Thus, the tip of the spout can be directly connected to the soot tube. Then, the nutrient can be supplied to the stomach or intestine of the patient through the tubule with almost no leakage of the nutrient from the connection portion between the spout and the tubule.
In the invention of claim 4, the spout and the sputum can be well connected using the adapter, and the nutrient does not leak when supplying the nutrient in the container.

In addition, by selecting the shape of the adapter, it can be applied to various types of soot tubes.
In the invention of claim 5, since the spout body is covered with the lid, the contained nutrient can be stored hygienically. In addition, when the supply of nutrients is interrupted for a short time, the spout body can be closed using the lid, so that the nutrients are not exposed to various germs.

  If the container containing the nutrient solution and the adapter are sold and stored as a set as in claim 6, it is possible to provide a nutrient for supplying a fistula tube that is a single-use type that does not require labor for preparation.

Hereinafter, embodiments of the present invention will be described more specifically.
FIG. 1 is an exploded perspective view for explaining the configuration of a nutrient solution container for feeding a sputum according to an embodiment of the present invention. The container 10 has a bag 11 for containing a nutrient and a spout 12 attached to the bag 11. In this embodiment, the bag 11 is formed by adhering four pieces of sheets 13, 14, 15, and 16. Each of the sheet pieces 13 to 16 can be composed of a polymer resin sheet or a laminated sheet of resin and aluminum foil or the like. In this embodiment, a sheet piece having a four-layer structure of PET (thickness: 12 μm), aluminum foil (thickness: 9 μm), ON (stretched nylon) (thickness: 15 μm), and polyethylene (thickness: 80 μm) is used.

And the four sheet pieces 13-16 are mutually melt | fused by overlapping those outline parts, and being heated and pressurized, and the bag 11 is formed. And in the bag 11, the storage chamber 17 for accommodating a nutrient is formed.
The description regarding the bag 11 is merely an embodiment, and the configuration of the bag 11 is not limited to the above-described content. For example, the bag 11 is not formed by bonding four sheet pieces as described above, but may be formed by bonding a pair of sheet pieces, or both ends of a cylindrical sheet are bonded. It may be a bag in which the storage chamber 17 is formed. Moreover, the raw material of the sheet piece which forms the bag 11 is not limited to the above-mentioned laminated sheet piece.

In short, the bag 11 is deformed in response to an external force, whereby the nutrient contained in the storage chamber 17 is discharged from the spout 12, and the deformed bag 11 is naturally restored to its original shape even when the external force is removed. What is necessary is just to be formed with the material which does not.
The spout 12 can be divided into a body 18, a nozzle 19 and a cap 20. The base side 21 of the main body 18 is attached to the bag 11 so as to communicate with the storage chamber 17. A specific mounting structure can be realized by bonding the sheet pieces 13 and 14 constituting the bag 11 so as to sandwich the root portion 21 therebetween. In this embodiment, the root portion 21 has a short cylindrical shape. However, the shape is not limited to this, and the root portion 21 extends into the storage chamber 17, and an intake port extending in the longitudinal direction is formed on the peripheral surface thereof. It may be a shaped shape.

  The spout body 18 is provided with a flange 22, and a nozzle 19 extends on the front side of the flange 22. The nozzle 19 has a tapered shape whose outer shape narrows toward the tip. A large number of ring-shaped irregularities rising in the direction orthogonal to the length direction and inclined toward the front are arranged on the outer peripheral surface toward the tip. The ring-shaped irregularities 23 serve to prevent the nozzle 19 from easily falling out of the soot tube when the nozzle 19 is inserted into the soot tube.

A cap 20 is integrally formed at the tip of the nozzle 19. The cap 20 is removed from the tip of the nozzle 19 by twisting and the tip of the nozzle 19 is opened.
In this embodiment, the spout 12 is integrally formed of high-density polyethylene. The spout 12 only needs to be formed of a material that can be heat-sealed with the bag 11 and is not limited to the above materials.

The following can be illustrated as nutrients put into the storage chamber 17 of the container 10.
First, the composition of the nutrient is as follows.
(1) As a composition, a gelled nutrient containing protein, carbohydrate, lipid, vitamin, mineral, and dietary fiber and adjusted to 1 Kcal / 1 g.

(2) As a protein, carbohydrate, lipid, and dietary fiber, a gelled nutrient containing 5 g of protein, 14.7 g of carbohydrate, 2.2 g of lipid, and 17 g of dietary fiber with respect to 100 g of the nutrient.
(3) Vitamin A is 250 IU, Vitamin D is 25 IU, Vitamin B ₁ is 0.20 mg, Vitamin B ₂ is 0.20 mg, Vitamin B ₆ is 0.30 mg, Niacin for 100 g of gelled nutrient There 1.45 mg, pantothenic acid 1.00 mg, folic acid 0.04 mg, vitamin B ₁₂ is 0.30Myug, vitamin C 80 mg, vitamin K is 5.5Myug, gelled nutritional vitamin E containing 3.0mg .

  (4) As minerals, 145 mg of sodium, 125 mg of potassium, 27 mg of magnesium, 59 mg of calcium, 60 mg of phosphorus, 1.0 mg of iron, 13 μg of iodine, 0.34 mg of manganese and 100 g of gelling nutrient A gelling nutrient containing 0.15 mg of copper, 1.5 mg of zinc, 5.0 μg of selenium, 3.0 μg of chromium, and 3.2 μg of molybdenum.

(5) As a gelling agent, a gelling nutrient containing one or more of agar, carrageenan, pectin, gellan gum, locust bean gum, xanthan gum and gum arabic. In addition, the compounding quantity mix | blends 2 g or less with respect to the gelled nutrient 100g.
Next, the physical properties of the nutrient are as follows.
(1) A gelling nutrient having a pH of 6.0 to 8.0 at the time of product.

(2) Hardness should just be hardness enough to squeeze out from the container 10, Preferably, it is a gelatinization nutrient which is 2000-20000 N / m < ² >.
Next, the manufacturing method of a nutrient and the filling method to the container 10 are demonstrated.
(1) A gelling nutrient that has been sterilized by heating at 120 ° C. for 4 minutes or more.
(2) A specific production method is to sufficiently disperse and dissolve nutrient components such as proteins, carbohydrates, lipids, vitamins, minerals and dietary fiber in warm water (about 80 ° C.). Warm water (about 80 ° C.) is added to the dispersed / dissolved liquid to obtain a preset weight. In order to homogenize this dispersion / dissolution solution, an emulsification operation using pressure is performed to prepare a nutrient solution homogenization solution. Separately, after the gelling material is dispersed in water (room temperature), a gelling agent solution dissolved by heating is prepared, mixed well with the nutrient solution homogenizing solution, and filled into the container 10. The container 10 filled with the gelling nutrient is put in a sterilization pot and sterilized by heating at 120 ° C. for 4 minutes or more.

  FIG. 2 is a diagram illustrating a configuration example of the container 10 according to another embodiment of the present invention, and in particular, a diagram illustrating a modification example of the spout 12. In the embodiment shown in FIG. 2, the spout 12 is provided with a flexible tube 24 between the main body 18 and the nozzle 19. That is, the rear end of the flexible tube 24 is connected to the front end of the main body 18, and the nozzle 19 is coupled to the front end of the flexible tube 24 having a certain length. With this configuration, since the nozzle 19 of the spout 12 can be freely operated with respect to the bag 11, there is an advantage that the nozzle 19 can be easily set on a soot tube or the like. In particular, when the fistula attached to the patient has a small amount of protrusion protruding from the patient's abdomen to the outside, the nozzle 19 is directly connected to the fistula to supply nutrients.

  If the tip of the nozzle 19 is covered with, for example, a silicon rubber cap 25, it is advantageous from the viewpoint of hygiene when the administration of the nutrient is temporarily interrupted. FIG. 3 is a diagram showing a configuration of the container 10 according to still another embodiment of the present invention, in particular, a modified example of the spout 12. In this embodiment, the spout 12 includes a spout body 18 and a lid 26. A thread 27 is formed at the tip of the spout body 8 (the side protruding from the bag 11). The lid 26 has a thread 28 formed on the inner side thereof, and is screw-coupled so as to be fitted to the spout body 18. Thereby, the spout 12 of the container 10 can be recapped. In this embodiment, an adapter 30 compatible with the lid 26 is provided. The adapter 30 has a base 31 with a thread 28 cut on the inside, similar to the lid 26, and a nozzle 32 projects forward from the base 31. The nozzle 32 has a tapered shape whose outer shape narrows toward the front. Preferably, the peripheral surface is formed with unevenness 23 arranged forward.

As shown in FIG. 3, the container 10 containing the nutrient is handled as a set of the spout 12 and the adapter 30 compatible with the lid 26 of the spout 12, so that it can be used up easily and can be easily handled. It is possible to provide an agent.
The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.
