Description

[Detailed description of the invention] (Field of industrial application) This invention relates to medical tubes such as tubes for administering enteral nutrients used in enteral nutrition methods, and particularly relates to improvements in the connector connected to one end of the tubes. .

(Prior art) Enteral nutrition is a method in which a tube for administering enteral nutrition is introduced into the esophagus through the nasal cavity to supply necessary nutrients, etc. In some cases, it is combined with parenteral nutrition. Sometimes used in combination. The tube for administering enteral nutrition used in this enteral nutrition method has a connector connected to the tip of the line for administering enteral nutrition at its outer end. A conventional Luer taper connector of the same type as the parenteral nutrition tube connector used in parenteral nutrition was used.

Therefore, there is a risk of accidentally connecting the enteral feeding line to the parenteral feeding tube connector, which can lead to serious complications as enteral feeding is usually not completely sterile. I can think of things.

(Problem to be solved by the invention) As a way to completely avoid the above-mentioned connection errors, the connector at the tip of the enteral nutrition administration line should have a completely different taper shape from the Luer taper connector at the tip of the parenteral nutrition administration line. Therefore, it is conceivable that the connector at the tip of the enteral nutrition administration line is shaped so that it cannot fit at all with the connector at the outer end of the parenteral nutrition administration tube. In this case, the shape of the fitting portion of the connector at the outer end of the enteral nutrient administration tube must also be changed so that it can be connected to the enteral nutrient administration line.
However, if necessary, a syringe or the like may be connected to the tube for administering enteral nutrients, and if the connector at the outer end of the tube for administering enteral nutrients is changed as described above, It is necessary to prepare a syringe with a special taper or a special adapter, which is extremely inconvenient.

(Means for Solving the Problems) The present invention has been made in view of the above circumstances, and has a female mouth shape of a connector at the outer end of a medical tube, for example, a tube for administering enteral nutritional supplements. The above problem was solved by changing the shape of the tube from the conventional one so that the connector of the parenteral nutrition administration line cannot be fitted to it, and also making it fit with a syringe having a normal Luer taper tip. The aim is to

That is, this invention provides a medical tube comprising a tube body having a fluid flow path and a connector for connecting an external device connected to one end of the tube body, wherein the connector has a first female opening. a connector body which is connected to the connector body via a bendable connecting member, whose outer wall surface is fittable to the first female opening, and further has a second female type therein. The present invention provides a medical tube characterized in that it is equipped with an adapter having a mouth formed therein.

Preferably, the first female opening has a taper other than the normal Luer taper generally used in parenteral nutrition lines, and the second female opening has a normal Luer taper. Further, the connector is connected to the connector body or the adapter via a bendable connecting member,
It is preferable to include a stopper that can fit into the second female opening.

(Function) In the medical tube such as the enteral nutrition administration tube of the present invention, the female opening of the connector body is different from the normal Luer taper used in general parenteral nutrition lines, and the taper angle of the opening and fitting wall surface. Because of the marked difference between the connectors of the enteral nutrition line that should be fitted and connected to this, it is impossible to fit the connector of the medical tube such as the intravenous nutrition administration tube, and the conventional Therefore, there is no need for doctors, nurses, etc. to accidentally connect the connector of the enteral nutrition line to a medical tube such as a tube for administering parenteral nutrition.

Further, when it is necessary to connect a syringe having a normal Luer taper to a medical tube such as a tube for administering enteral nutrition, it can be easily connected by using an adapter connected to a connector.

(Embodiments) This invention will be described below with reference to illustrated embodiments.

Figure 1 shows the connector part of the tube for administering enteral nutritional supplements according to the present invention, which is a catheter for introducing nutritional supplements (including normal nutritional supplements, cleaning fluids, and drugs) into the intestines. Tube type 10
A connector main body 11 is connected to the outer end of the connector.
This connector body 11 is formed with a first female opening 11a that communicates with the tube body 10 (see FIG. 4). This first female mouth portion 11a
The caliber of the luer taper at the tip of a normal parenteral nutrition line (not shown) is significantly different from the angle of inclination of the taper surface, and the caliber also does not fit.

A thin plate-shaped flexible connecting member 12 extends in a substantially horizontal direction (perpendicular to the outer wall surface) on the upper part of the outer wall surface of the connector body 11, and a truncated cone-shaped adapter 13 is attached to the tip of the flexible connecting member 12 with a large diameter. Connected via the periphery. This adapter 13 has an outer wall surface 13a that can be fitted into the first female opening 11a, and has a second female opening 13b (internal passage) formed at its axis. This second female mouth part 1
3b has a luer taper of the same type as the luer taper at the tip of a normal syringe, and can be connected to each other. A thin plate-like connecting member 14 similar to this connecting member 12 extends on the outer wall surface of this adapter 13 at the opposite peripheral edge opposite to the connecting portion with the tip of the connecting member 12, and the second female type is attached to the tip of the connecting member 14. A generally frustoconical plug body 15 that can fit into the mouth portion 13b is connected.

The connector main body 11, the connecting members 12, 14,
The adapter 13 and the stopper 15 are made of a relatively flexible thermoplastic synthetic resin generally used for medical purposes, and can be easily integrally molded by injection molding or the like.

When using this enteral nutrition administration tube, first the tip is introduced into a predetermined position in the body through the nasal cavity 16 as shown in FIG. Open it as shown, fit the connector (not shown) at the tip of the enteral feeding line into the first female mouth part 11a,
Introduce nutritional supplements, etc.

After the introduction of this nutritional supplement, if necessary, a cleaning solution, a medicinal solution, etc. is introduced into the intestine using a syringe or the like having a normal Luer taper connection end. In this case, as shown in FIG. The first female opening 11a is fitted into the first female opening 11a, and a syringe or the like is connected to the second female opening 13b.

Furthermore, when not in use, the plug is fitted into the second female opening 13b, as shown in FIG.

In addition, in the above embodiment, the adapter 13 and the stopper 15 are
Although an example has been described in which the
As shown in the figure, the adapter 13 and the plug 15 are connected directly to the connecting member 1 from the peripheral wall surface of the connector body 11.
2 and 14 may be extended, and the adapter 13 and the stopper 15 may be connected to their tips, respectively. In this case as well, the same effects as in the above embodiment can be obtained.

In the above embodiments, the tube for administering enteral nutrients has been described, but the present invention is not limited to this, and can be applied to other medical tubes used for the same purpose.

(Effects of the invention) As detailed above, according to the medical tube such as the enteral nutrition administration tube of the present invention, the enteral nutrition to be fitted into the first female opening of the connector body. Since the connector at the end of the line can no longer be connected to the connector of a medical tube such as a parenteral nutrition tube made of a normal Luer taper, enteral nutrition may be accidentally administered to the parenteral nutrition tube. There is no need to worry about being rejected. Furthermore, if it is desired to connect to a syringe or the like having a normal Luer taper tip, the adapter 13 can be used, so that no operational inconvenience occurs.
