Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a fistula appliance that is attached to an artificially created fistula in the human body and used to discharge excrement.

[Prior art]

Patients who have undergone colostomy, ileostomy, ureterostomy, or similar surgery due to rectal or bladder disease, and a fistula is created by guiding the intestinal tract, ureter, or other similar tubes to the body surface. Patients suffering from this condition are always incontinent, so a device is usually attached to the fistula so that excrement can be stored in a bag at any time. Most of the conventional braces used for this purpose are fixed to the body with adhesive, which causes rashes from the adhesive and stains on the body surface from excrement, and requires the patient to carry a bag at all times. Many were also dissatisfied with the fit.

[Purpose of invention]

The purpose of the present invention is to provide a fistula appliance as described above that can be securely fixed to the body surface, does not require a bag for excretion, is easy to dispose of afterwards, and is comfortable to wear for the patient. The purpose is to obtain an orthosis.

[Structure of the idea]

The above object is achieved according to the present invention, which comprises a double ring-shaped main body, a cap that fits into the main body, and an intermediate body that is inserted through a hole formed in the cap and projects into the main body, and the intermediate body is inside. It includes a liquid passage and an air passage, the liquid passage has a valve mechanism at the outer end and a through hole at the inner end, the air passage has a valve mechanism at the outer end, the inner end is closed, and air is passed through the valve mechanism. This is accomplished by forcing air into the passageway so that the inner end expands. By suturing the outer end of the intestinal tract or ureter guided to the body surface to the body surface so as to straddle the double rings of the main body, the main body is securely fixed to the fistula, and the cap is always attached to the main body. At the same time, the inflated part at the inner end formed by pressurizing air into the air passage of the intermediate body blocks the intestinal tract or urinary tract, thereby preventing the leakage of excrement, and removing the excrement accumulated in the body. The cap is removed and the cap is expelled from the body, and the interior is cleaned and disinfected by injecting cleaning liquid from the liquid passageway in the intermediate body.

[Example of idea]

Next, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are a front view and a side view, respectively, of the main body. Main body 1 has inner ring 2 and outer ring 3
A double ring shape is formed by both rings 2,
3 are mutually connected by a plurality of bridge bodies 4.
Each of the ends of the outer ring 3 on the same diameter has a cap clamp 5, and the cap clamp 5 includes a holding piece 6 having a U-shaped cross section and a notch 7 provided inside the holding piece 6.
The cap, which will be explained next, is fitted into the cap.

3 and 4 are a front view and a side view of the cap, respectively, and FIG. 5 is a vertical sectional side view taken along the line -- in FIG. 4. The cap 8 has an umbrella-shaped portion 9 and a hollow trunk 10 extending in the shape of an inverted cone at its center, and engagement pieces 11 projecting inward are provided at both ends of the open edge of the umbrella-shaped portion 9. It is formed.

FIG. 6 is a side view of the intermediate body. The intermediate body 12 is formed by a Y-shaped tube consisting of a leg portion 13 and forked portions 14 and 15. An air inlet 16 and a valve mechanism 17 are provided at the end of the forked portion 14, and an air inlet 16 and a valve mechanism 17 are provided at the end of the forked portion 14. A liquid inlet 18 and a valve mechanism 19 are provided at the end of the bifurcated portion 15 . The valve mechanism 17 has a leg portion 1.
An air tube 20 extending inside the leg 13 is connected, and its tip communicates with an air chamber 21 formed by a double wall near the tip of the leg 13, thereby forming an air passage. A liquid tube 22 extending into the leg 13 is connected to the valve mechanism 19, and its tip communicates with a through hole 23 provided at the tip of the leg 13 to form a liquid passage.

Next, we will explain how to use this orthosis.

As shown in FIG. 7, the inner ring 2 of the main body 1 is applied to the opening of the intestinal tube 24 that has been surgically pulled out to the surface of the body, and the distal end 25 of the intestinal tube 24 is turned over outward to straddle the inner ring 2. Inner ring 2
It is passed through the gap 26 between the outer ring 3 and the outer ring 3 and sutured onto the body surface 27. In this way, the main body 1 is securely fixed to the patient's fistula. The legs 13 of the intermediate body 12 are press-fitted into the holes in the main body 10 of the cap 8, and the cap 8 is pushed onto the main body 1 with its engaging piece 11 facing the cap clamp 5 of the main body 1. The engaging piece 11 engages in the notch 7 while pushing the holding piece 6 of the main body 1 sideways, and the holding piece 6 returns to its original position due to its elasticity. The inner periphery of the cap 8 is in close contact with the outer periphery of the outer ring 3 of the main body 1. In this state, the legs 13 of the intermediate body 12
The tip of the tube protrudes into the intestinal tract 23. When air is injected through the air inlet 17 of the intermediate body 12 using an air injection machine, the air reaches the air chamber 21 at the tip through the air tube 20, expands the air chamber 21, and obstructs the intestinal tract 24.

When excretion occurs, the excrement that has descended into the intestinal tract is stopped by the swollen portions of the legs 13 of the intermediate body.
It will be stored there. If a leak were to occur, the leakage would be prevented by the liquid tightness between the hole in the main body 10 of the cap 8 and the inserted intermediate body 12, and by the fit between the main body 1 and the cap 8. be done. When more than a certain amount of excrement has accumulated, the cap 8 can be easily pulled out and removed by pulling the holding piece 6 of the cap clamp 5 of the main body 1 slightly outward, so that the excrement can be disposed of outside. . When the cap 8 is fitted into the main body 1 again and the cleaning liquid is poured from the liquid inlet 18 of the intermediate body 12, the liquid passes through the liquid tube 22 and is injected into the intestinal tract through the through hole 23, thereby cleaning the intestinal tract and the fistula. Can be done.

For example, an activated carbon gas venting filter can be attached to the cap 8.

The materials constituting the main body, cap, and intermediate body may be any so-called biological materials, such as silicone, polytetrafluoroethylene, polyurethane, synthetic rubber, natural rubber, polyethylene, polyester, polycarbonate, nylon, or composite materials thereof. can be used.

[Effect of idea]

The effects obtained by the present invention are as follows.

(1) Since this method uses the intestinal tract or ureter directly to adhere to the fistula, there is no need to use adhesives as in conventional methods, there is no rash, and there is no need to stain the body surface with excrement. Very few.

(2) Since the orthosis is securely fixed to the body surface and there is no need to carry a bag for excrement as in the past, patients do not have any anxiety about wearing it, and post-treatment is easy and comfortable. You can lead a normal daily life.

(3) Since the intestinal wall is supported by the expanded portion of the intermediate, contraction of the intestinal tract after surgery can be prevented.
