Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an infusion circuit for medically injecting various chemicals into a living body.

(Prior Art) The infusion circuit is composed of parts such as an introduction needle, an infusion tube made of soft plastic, a dropping pipe made of hard plastic, a clamp, a filter, and a side injection pipe, and medically injects various liquid medicines into the living body. Used for. However, so-called catheters that are connected to the tip of the infusion circuit and inserted directly into the patient's body are not included in the infusion circuit. An infusion circuit in which these parts are fixedly joined and integrated from the beginning has also been proposed (Shokai 62-139540).

In recent years, with the advancement of medical treatment, there are many types of liquid medicines that are administered to patients using an infusion circuit. Often administered. In addition, administration may be performed from a plurality of punctured blood vessel portions using a plurality of main infusion circuits, and various monitoring circuits and washing circuits are often attached to the patient's body. Therefore, various infusion circuits and circuit components exist in a complicated manner around the patient. FIG. 5 shows the implementation status of such infusion.

At the time of infusion, it is necessary to look for the corresponding drip tube, clamp, side injection pipe, etc. to check the flow rate of the medicinal solution and replace the medicinal solution bag or the infusion circuit itself. However, this work is not only time consuming but also prone to error. For example, if a parenteral nutrition agent is administered through the puncture blood vessel and concurrently enteral nutritional agents are administered nasally, there is no major problem if the parenteral nutrition agent enters the intestine by mistake. However, if enteral nutrition enters the blood vessels, there is a risk of fatal accident. And there are few such accidents, but they are actually happening.

(Problems to be solved by the invention) However, conventionally, the structure of each infusion circuit for various uses is almost common, and no infusion circuit pays particular attention to the above-mentioned problems. Therefore, in the present situation, the identification of which infusion circuit is being used for which drug solution is left to the care of the operator as described above.

Therefore, in order to prevent an unexpected accident in handling the infusion circuit, which is becoming more and more complicated as described above,
An object of the present invention is to provide an infusion circuit in which it is easy to identify the flow direction of an infusion and the infusion line.

(Means for Solving the Problems) In order to solve the above problems, an infusion circuit according to the present invention comprises:
Among the constituent parts, at least one selected from an infusion tube, a dropping cylinder, a clamp, a filter, and a side injection pipe has an identification mark made of a colored flow direction symbol.

(Examples) Hereinafter, some examples of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of an identification mark given to an infusion tube forming a part of an infusion circuit according to the present invention. The same figure (a) shows the continuous line and the V-shaped flow direction symbol colored on the side of the infusion tube, and the same figure (b) shows the broken line or dotted line and the V-shaped flow direction symbol. Similarly, (c) shows a combination pattern of a long line and a triangular flow direction symbol. However, these are only some of the examples of the identification display.
In the present invention, in addition to the flow direction symbol, for example, characters are included, parallel lines, spiral continuous lines, a large number of circular patterns that surround the outer circumference of the tube are arranged in the longitudinal direction, and various displays such as a mesh pattern are also described. it can. The entire surface of the infusion tube may be colored transparently.

The color used for coloring is not particularly limited. That is, one or more colors are selected from all chromatic colors and all achromatic colors other than colorless and transparent.

The infusion tube is the most prominent part in the infusion circuit,
If at least one side surface thereof is provided with an identification mark composed of a flow direction symbol, it becomes easy to identify the infusion circuit used for a specific drug solution and the infusion direction. Further, by providing such an identification mark on a plurality of infusion tubes constituting the infusion circuit, the visual recognition effect can be further enhanced, and further such an indication can be applied not only to the infusion tube but also to the dropping cylinder, the clamp, the side injection pipe, etc. The same effect can be expected even if it is applied or if such a display is applied only to these parts other than the infusion tube.

FIG. 2 is a cross-sectional view of a transparent tube provided with a colored portion for a flow direction symbol for providing an identification mark according to the present invention. For example, the colored portion of the flow direction symbol can be provided on one side of the tube as in the upper figure, or on both sides of the tube as in the lower figure. Although not shown, colored portions for flow direction symbols may be provided on three sides or the entire surface. In this figure, the colored portion of the flow direction symbol extends to the thick portion of the tube, but if the durability is assured, the flow direction symbol may be colored only on the surface by printing, for example.

FIG. 3 shows a state in which an infusion tube having an identification mark composed of a flow direction symbol on its side surface is joined to a side injection pipe. The figure (a) shows the case where the continuous line and the V-shaped symbol are marked on the main chemical liquid line, and the figure (b) shows the case where the dotted line and the triangular symbol are marked on the side-injection line. FIG. 6C shows a case where identification marks are provided on both the infusion tube and the side injection tube.

FIG. 4 is an explanatory diagram showing a situation in which an infusion solution circuit, in which the above-described identification-indicating parts are assembled, is used in parallel with an infusion solution circuit having no identification indication. The infusion circuit with the identification mark can be easily distinguished from the other one. Further, the flow direction of the infusion can be determined, and the infusion circuit can be easily traced to the patient side or the infusion back side only by looking at a part of the infusion circuit. It should be noted that this drawing is created from the same original drawing as FIG. 5 for explaining the conventional technique for comparison.

(Effects and effects of the device) When the infusion circuit according to the present invention is used, for example, in the main drug solution line, the line of the secondary drug solution and the line of the main drug solution which are administered via the side injection pipe can be distinguished at a glance. be able to. When multiple main chemical liquid lines are used simultaneously in parallel, by using the infusion circuit according to the present invention in one of them, one line can be Easy to identify. Further, it is possible to determine in which direction the infusion in the infusion line is flowing, and the infusion circuit can be easily traced to the patient side or the infusion back side only by looking at a part of the infusion line.

This makes it possible to easily and definitely identify the infusion circuit that is aimed at when checking the infusion rate during infusion or when exchanging the infusion bag or the infusion circuit itself, so that unexpected accidents can be prevented and work time can be reduced. It can be shortened.
