Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe closing device used for removing urine stones accumulated in a urinal drainage pipe.

[0002]

2. Description of the Related Art As a conventional cleaning method for pipes, a method of physically removing urine stones by high pressure cleaning is generally used. In addition, a method is also used in which the chemical is flowed into the pipe to remove it. Further, as a conventional technique, JP-A-4-24335,
There is an obturator as described in JP-A-7-248091 and JP-A-9-125274 for forming a balloon member at the tip and closing the inside of a tube to temporarily store a drug.

[0003]

The conventional method of using high-pressure washing water has a risk of damaging an existing old pipe and causing water leakage. Further, the method of flowing the medicine into the pipe is not effective because the medicine flows and the urine stones adhering to the drainage pipe of the urinal cannot be sufficiently dissolved. In addition, the technique disclosed in Japanese Patent Laid-Open No. 4-248335 and Japanese Patent Laid-Open No. 9-125274 are sufficient because the hose is a soft and soft material when urine stones are accumulated in the tube when inserting the balloon. There was a problem that it could not be inserted. Further, in Japanese Unexamined Patent Publication No. 7-248091, since the balloon member is made to flow by the force of water, it is impossible to insert the balloon member to an arbitrary position in the pipe when the pipe is blocked by urine stones. .

Therefore, according to the present invention, even if urine stones are attached to the drainage pipe of the urinal, the pipe closing member is surely sent to an arbitrary position to expand the elastic member so as to close the inside of the pipe, and the inside of the pipe can be blocked by a medicine or the like. It is an object of the present invention to provide an intraluminal blockage device capable of removing urinary stones.

[0005]

In order to achieve the above object, the invention according to claim 1 provides a rigid wire capable of freely advancing in a pipe in a pipe closing device and a tip of the wire. A distal end guide having rigidity similar to that of the wire provided, an in-tube closing member having an elastic member capable of expansion and contraction provided between the leading end guide and the wire, and the in-tube closing member. It is characterized by comprising an air supply pipe connected thereto.

According to the present invention, by providing a wire having rigidity capable of freely advancing in the tube and a tip guide tool having the same rigidity as the wire provided at the tip of the wire. Even if urine stones are deposited and the inner diameter of the drain pipe is narrowed, it is possible to advance the inside of the pipe while pushing the urine stones apart. It is possible to insert the in-pipe closing member up to a relatively small amount of urine stones, supply air by the air supply pipe, expand the elastic member of the in-pipe closing member, and close the drainage pipe. Therefore, even if urinary stones are deposited and the inner diameter of the tube is narrowed, the urinary stones can be removed by the chemical agent.

According to a second aspect of the present invention, in the pipe closing device according to the first aspect, the elastic member and a core member that is separate from the elastic member and has the same rigidity as the wire are provided. , The core member is disposed inside the elastic member, and in a state where the elastic member and the core member are combined, a gap that can expand when the elastic member expands by introducing air, It is characterized in that it is between the elastic member and the core material.

According to the present invention, the elastic member and the core member which is a separate body from the elastic member and has the same rigidity as the wire, are provided inside the elastic member. Since it is installed, the force to insert the wire,
In addition to the effect of the invention of claim 1, the urinary stone is further pushed out even if the urinary stone is deposited and the inner diameter of the tube is narrowed because it is transmitted to the tip guiding tool without escaping at the portion of the in-pipe blocking member. It is possible to proceed inside the pipe. Further, since the wire, the tip guide tool, and the core material of the in-tube closing member are rigid, the elbow portion can also bend along the shape of the tube and proceed in the tube. Further, in a state where the elastic member and the core member are combined, a gap that can be expanded when the elastic member is expanded is provided between the core member and the elastic member, so that the elastic member has a part. The entire circumference can swell without bulging only, and the inside of the pipe can be reliably closed.

According to a third aspect of the present invention, in the in-pipe closing device according to the second aspect, the elastic member of the in-pipe closing member is:
It is characterized in that it is composed of an elastic member forming the outside and an elastic member forming the inside, and the elastic member forming the inside is bellows-shaped.

According to the present invention, the elastic member of the in-pipe closing member is composed of the elastic member forming the outside and the elastic member forming the inside, and the elastic member forming the inside has a bellows shape. When the elastic member constituting the outer side is expanded by introducing air, it can be expanded more evenly.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to the drawings. Figure
FIG. 1 is an external view of a pipe closing device according to the present invention. Figure 1
In the figure, reference numeral 1 is a pipe closing device. A tip guide tool provided with an egg-shaped tip guide ball 10 installed at the tip of the wire 2 so that it does not stop at the bend of the drainage pipe at the tip of the rigid wire 2 that can freely move inside the tube. There is an in-pipe closing member 3 having an elastic member 5 that is inflatable and contractible between the wire 2 and the tip guiding tool 4 connected to the wire 4. The air supply pipe 8 is connected. An air supply pump 7 for introducing air is provided at the tip of the air supply pipe 8.
Then, the elastic member 5 of the in-pipe closing member 3 is expanded. Ideally, the material of the air supply pipe 8 is Teflon (registered trademark) or a silicon tube so as not to be affected by a urinary stone removing agent. Further, there is an air valve 6 for stopping air between the air supply pipe 8 and the air supply pump 7, and when the elastic member 5 of the in-pipe closing member 3 is expanded, the air valve 6 is closed and expanded. After maintaining the state and removing the urine stones with the chemical, the air valve 6 is opened to remove the air. The material of the wire 2 is preferably iron and has a spring shape.

FIG. 2 is a cross-sectional view of the drainage pipe, showing a state in which the tip guide tool 4 of the present invention passes through the drainage pipe filled with urine stones 9. When the tip guide tool 4 contacts the urine stone 9 at the bent portion 11 of the drainage pipe, and when the urine stone 9 is softer than the wire 2, the wire 2 is inserted so that the wire 2 pushes the urine stone 9 out. You can pass through. When the urine stone 9 is harder than the elasticity of the wire 2, the egg-shaped tip guide ball 10 provided at the tip of the tip guide 4 can avoid the urine stone 9 and proceed. The tip guide tool 4 made of the same material as the rigid wire 2 has a spring-like structure in shape and is characterized in that it can be flexibly bent at the bent portion 11 of the drainage pipe. There is.

FIG. 3 shows an embodiment in which the in-pipe closing device 1 is actually used. The urinal 12 at the position closest to the vertical pipe 34 is removed, and the wire 2, the tip guide tool 4, and the intraluminal closing member 3 are inserted. Attach the tip guide 4 to the vertical pipe 3
4 is inserted to a position close to 4, and the pipe closing member 3 is expanded by sending air by the air supply pump 7. After being blocked by the in-pipe blocking member 3, the urinary stone removing agent 13 is removed from the drainage pipe of the urinal 12 to the inflow side pulling tube 14 to obtain the agent 1.
Fill with 3. At this time, the cleaning port 30 at the end of the horizontal pipe 14
Is closed so that the drug 13 does not leak out. After leaving for about 30 minutes, the air is evacuated and the medicine 13 is allowed to flow to complete the removal of urinary stones in the tube.

FIG. 4 is a view in which the inside of the in-pipe closing member 3 is seen through. The in-pipe closing member 3 includes an elastic member 15 forming an outer side, an elastic member 16 forming an inner side, and the elastic member 1
It is composed of a fixing member 17 for fixing 5 and 16, and a core material 35 having the same rigidity as the wire 2. The elastic members 15 and 16 are made of rubber. Further, the core member 35 is a shaft member 36 made of the same material as that of the wire 2, and a retaining member 1 for the elastic members 15 and 16 arranged at both ends of the shaft member 36.
It is composed of 8 and 20. The retainer 18 is connected to the shaft member 36 by a screw portion 22 (see FIG. 6),
The fixing member 17 and the retaining member 18 are fixed by adhesion or welding. The retainer 20 is bonded or welded to the shaft member 36 so as to be integrated. The elastic member 15 preferably has a rubber tube shape and an outer diameter of 20 mm or less so that the 50 mm pipe can pass through the pipe blocked with urine stone up to 40 mm.

FIG. 5 is a view showing a state in which the in-pipe closing member is expanded in the drainage pipe. In addition, FIG.
5 shows a state in which an in-tube closing member having a gap between the elastic member and a core material separate from the elastic member is expanded, and FIG.
(B) is a diagram showing a state in which the in-pipe closing member having no gap between the elastic member and the core member separate from the elastic member is expanded. When air is injected from the air supply pipe 8 between the elastic member 15 and the elastic member 16, in the case of the in-pipe closing member having a gap between the elastic member and the core member shown in FIG. When 15 and 16 swell and extend in the axial direction of the core material 35, they can extend in the axial direction by the gap 25 between the fixing member 19 and the retaining member 20, so that they can swell without deviation. In the case of the in-pipe closing member having no gap between the elastic member and the core material shown in (b),
When the elastic members 15 and 16 expand and extend in the axial direction of the core member 35, there is no gap between the fixing member 19 and the retaining member 20, so a force is applied in the direction in which the shaft member 36 of the core member 35 is extended. Since the shaft member 36 bends, the elastic member 15 swells in a biased state. Although the drainage pipe 23 can be closed even if the elastic member 15 expands in a biased state, it may be a pipe closing member having a gap between the elastic member and the core member shown in FIG. 5A. If so, the drainage pipe 23 can be blocked more reliably.

FIG. 6 is a sectional view of the pipe closing member 3 according to the present invention. The fixing member 17 and the retaining member 18 fixed to the fixing member 17 by adhesion or welding are fixed to the shaft member 36 by the screw portion 22. Reference numeral 15 is an elastic member forming the outer side, and 16 is an elastic member (inner rubber) forming the inner side. The shape of the elastic member 16 forming the inner side is a bellows shape, the contact area with the shaft member 36 is reduced, and the elastic member 15 forming the outer side can be smoothly expanded. In addition, the cross-sectional shape of the elastic member 15 forming the outside needs to pass through a thin drainage pipe, for example, about φ40 mm, and to expand the elastic member 15 forming the outside at a thick pipe, for example, a portion of φ75 mm to close the drainage pipe. In case of shrinkage, the outer diameter is φ20m
If it is m, the cross-sectional shape of the elastic member 15 may be circular as shown in FIG. 6 (b), but by making it octagonal or star-shaped, the circumference becomes longer, so that the drainage pipe with a larger diameter can be used. Even if there is, the inside of the drainage pipe can be satisfactorily blocked.

FIG. 7 is a diagram showing an embodiment of the present invention. The example of FIG. 7 is an example in which two in-pipe closing members 3 and 28 are provided, and if the wire 2 to which each in-pipe closing member 3 and 28 is fixed and the air supply pipe 8 are prepared with different lengths, It can be used properly depending on the insertion position of the in-pipe closing member 3. The actual usage will be described with reference to FIG. There is a cleaning opening 30 on the floor surface 29, and the tip guiding tool 4 is provided from the cleaning opening 30.
Is inserted, and air is supplied from the air supply pipe 8 connected to the distal pipe inner closing member 3 and the rear pipe internal closing member 28 to expand the distal pipe internal closing member 3 and the rear internal pipe closing member 28, The inside of the drainage pipe and the vicinity of the cleaning port 30 are closed. Next, the medicine 13 is poured from the urinal 12 to remove urine stones in the drainage pipe. Thereby, the medicine 13 can be poured in without removing the urinal 12, and the urine stone removing work time can be shortened.

FIG. 9 is a diagram showing another embodiment of the present invention. A drill 32 is provided at the tip, and a pipe closing member 33 is fixed behind the drill 32. When the urine stone is very hard and most of the drainage pipe is clogged, the drill 32 is rotated to widen the gap in the pipe to some extent, and the pipe closing member 3
3 can be inserted to any position. In this case, the air supply pipe 34 needs to be built in the wire 2 so that the air supply pipe 34 does not get entangled with the wire 2.

EFFECTS OF THE INVENTION According to the present invention, a wire having rigidity capable of freely advancing in a pipe and a tip guide tool having the same rigidity as the wire provided at the tip of the wire are provided. As a result, even if urine stones are deposited and the inner diameter of the drainage pipe is narrowed, it is possible to advance the inside of the pipe while crushing the urine stones. It is possible to insert the in-pipe blocking member up to a relatively small amount of urine stone and supply air by the air supply pipe to expand the elastic member of the blocking member to close the drainage pipe. Therefore, even if urinary stones are deposited and the inner diameter of the tube is narrowed, the urinary stones can be removed by the chemical agent.
