Abstract

PURPOSE:To easily insert a tube into a human body and to easily perform position movement in the human body by providing a guide controller insertion port at a position to which the tube is inserted at the middle part of the human body, and performing the position movement of the tip of the tube by inserting the guide controller. CONSTITUTION:Coating 10 with slime due to contact with water in the periphery is applied to the tube 1 for medical care to reduce a friction coefficient extending entire inner and outer surfaces, and a hole 30 introducing liquid and gas to outside the tube 1 is provided at the extreme tip of the tube 1. The guide controller insertion port 40 capable of inserting/extracting the guide controller as holding the sealed state of the tube is provided at the position at which it is inserted to the human body, and the positioning of the tip of the tube in the human body can be facilitated by inserting the guide controller. The position movement of the tip of the tube 1 for medical care can be easily performed by loading the guide roller 60 on the tube 1 for medical care, inserting the guide controller to the position of the guide controller insertion port 40 in the human body, and operating the guide controller 60 from outside the human body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a medical tube system used as an ileus tube or the like.

[Prior Art] Medical tubes used as ileus tubes and the like have been developed in various forms, an example of which is shown in FIG.

FIG. 6 is a sectional view for explaining a conventional medical tube system of this type, FIG. 6(A) is a sectional view showing the configuration of the medical tube, and FIG. 6(B) is a sectional view of the guide wire. In each figure, (1) is a medical tube, (2) is a guide weight, (3) is a side hole, and (4) is a guide wire.

The tube (1) is made of an elastic material, has a guide weight at its tip, and has a tube (1) on its side.
A side hole (3) is formed to guide the gas or liquid conveyed through the tube (1) to the outside of the tube (1).

Then, in order to smoothly advance the tip of the tube (1) to the target site in the intestinal tract, olive oil is injected into the inner cylinder of the tube (1), and a guide wire (4) is inserted from the end of the tube (1). Tube (1) in the human body in this state
Insert.

FIG. 7 is a sectional view showing an example of using the medical tube system shown in FIG. 6 as an ileus tube.
5) shows the balloon, (6) the stomach wall, and (7) the intestinal tract.

Next, the operation will be explained. The ileus tube is inserted into the human body to perform treatment with the aim of suctioning out the intestinal contents accumulated in the intestinal tract, depressurizing the intestinal tract, restoring intestinal spiral movement and improving passage through bent obstructed areas. First, as shown in Fig. 6(B), the guide wire (4) is inserted into the tube <1) and inserted into the side hole 3) of the tube (1). Attach the balloon (5) (not shown). Then, apply xylocaine jelly (lubricant) to the tip of the tube (1), which is approximately 10 cm or more long, and similarly drip xylocaine jelly into the entrance of the nostril into which it will be inserted. Then, insert the tip of the tube (1) through the nostril and push the tube (1) until it reaches the inside of the stomach 6). This state is shown in FIG. 6(A).

Once the tip of the tube (1) enters the stomach (6), the kite wire (4) is operated to move the tip of the tube (1) along the stomach wall using the kite weight (2). Direct it to the pylorus.

After confirming by X-ray whether the tip of the tube (1) has passed through the pylorus axis and advanced to the duodenum, a syringe (not shown) is attached to the end of the tube (1).
Physiological saline or the like is injected into the balloon (5) through the tube (1), and the balloon (5) is slightly inflated. This state is shown in FIG. 6(B). Since the subsequent operations are not directly related to this invention, they will be omitted here.

[Problems to be Solved by the Invention] As described above, the conventional medical tube system as described above uses a guide weight to move the tip of the tube to a desired position while being remotely controlled by a guide wire. However, there are problems in that it is very difficult to move the position within the human body, takes a long time, and causes great pain to the patient.

This invention was made in order to solve such problems, and provides a medical tube that can be easily inserted into the human body without requiring assistance such as a lubricant, and that can be easily moved within the human body. The purpose is to provide a system.

[Means for Solving the Problems] A medical tube system according to the present invention has a guide controller insertion port that allows insertion/evacuation of a guide controller while maintaining an airtight state of the tube. The guide controller was installed at a position midway into the human body, and the guide controller was inserted through this guide controller insertion port to move the position of the tip of the tube.

[Function] In the medical tube system of the present invention, the guide controller is inserted through the guide controller insertion port to move the position of the tube tip.
It becomes possible to easily move the position within the human body.

[Examples] Examples of the present invention will be described below with reference to the drawings. 1st
The figure is a sectional view showing the configuration of a medical tube according to an embodiment of the present invention, FIG. 2 is a partially enlarged view showing the vicinity of the insertion date of the guide controller of the tube shown in FIG. FIG. 3 is a partially enlarged cross-sectional view showing the vicinity of the tip of the shown tube. In the figure, (1) is the medical tube in this example, and in order to reduce the coefficient of friction on the entire inner and outer surfaces,
It is coated with a special coating (10) that becomes slimy when it comes into contact with surrounding moisture.

In addition, in this embodiment, in consideration of the case where it is used as a gastric probe, a hole (30) for guiding liquid or gas conveyed through the tube (1) to the outside of the tube (1) is provided at the tip of the tube (1). However, when considering the attachment of the balloon (50) when used as an ileus tube, the fifth
It can also be a side hole like the conventional tube (1) shown in the figure.

(20) is the guide weight in this example, and the first
As shown in Fig. 3, the spheres are divided into a plurality of spheres and arranged and embedded inside the diameter of the tube (1), thereby creating a hole (30) at the tip of the tube (1). Furthermore, even the part where the guide weight (20) is embedded can be easily bent.

(40) is the guide controller (
This is the guide/controller insertion port for inserting the guide/controller (described later), and is provided at an arbitrary position in the center of the tube (1), approximately 150 cm from the tip of the tube (1), and this guide/controller (4o) is also inserted into the human body. It is considered to be inserted. That is, the details are shown in Figure 2 (A).
As shown in the figure, the first occlusion valve (41) and the second occlusion valve (42)
When the occlusion valves <41) and (42) are viewed from the side of the tube (1), they form a cross (43) or a straight line (44) as shown in Figures 2 (B) and (C). The notches are provided at an angle so that the notches do not overlap in the same direction, and as shown in FIG. 2(D), each occlusion valve (41).

(42) is installed by stacking them. Therefore, the guide controller can be inserted relatively easily here, and the structure is such that the liquid or gas flowing inside the tube (1) does not leak from here to the outside, that is, the structure maintains the airtight state of the tube (1). can do.

In this embodiment, the guide/controller insertion port (40) as described above is provided at a position to be inserted into the human body, so that the guide/controller can be inserted into the human body at the tip of the tube (1). This makes positioning easier.

In this embodiment, the first obstruction valve (41) has a cross-shaped notch (43), and the second obstruction valve (42) has a straight notch (44), but the reverse is also possible, or both can be used. The blocking valves (41) and (42) may both be cross-shaped or linear, as long as the tube (1) is kept airtight and the guide controller can be inserted/ejected.
