Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a colostomy appliance for storing and discharging excreta by being attached to the opening of a surgically formed colostomy.

[Conventional technology]

A method of disposing of excrement that is discharged through the opening of an artificial anus created by pulling the intestines out to the surface of the body through surgery involves fixing a bag around the artificial anus and temporarily storing the excrement in this bag at any time. There is a method of removing the bag from around the colostomy in a timely manner, cleaning the bag, and reusing it. With this method, patients must wear the bag on their body at all times, which limits their activities due to concerns about the bag being damaged, and excrement discharged into the bag comes into contact with the area around the colostomy. There are many opportunities to do so and it is unsanitary. An alternative method is to directly block the colostomy with some means to store excrement in the intestines without using a bag, and when a certain amount has accumulated, remove the blocking means and remove the excrement from the colostomy. There are ways to get it out of the body. One method is to embed a permanent magnet inside the body near the colostomy, place a cap that also has a built-in permanent magnet over the colostomy, and use the attraction between both permanent magnets to bring the cap into close contact with the colostomy, thereby occluding it. It is.

This method cannot be used as the patient gains weight, as the distance between the magnets increases and the magnetic force decreases, creating the possibility of leakage, and the weight of the permanent magnets can cause a feeling of pressure and the colostomy tends to drop. However, there are problems such as foreign body reactions due to the embedded magnet, and the need for surgery to remove the magnet in the event of an abnormality or when it becomes unusable. The second method is to insert a plug having a balloon portion into the artificial anus and inflate the balloon portion to seal the intestinal wall. This method applies pressure to the intestinal lining, which causes the intestine to expand, so the balloon needs to be enlarged each time.
In addition, the intestines tend to become peristaltic due to stimulation, and cannot be completely sealed, causing constant small amounts of leakage.
The balloon is fixed under the intestinal epithelium, so if the balloon is inflated too much, it can stop the blood flow and cause necrosis (and there are other problems such as a foreign body sensation.The third method is to insert the plug into the colostomy using a belt). Although it is a pressing method, it is prone to necrosis because pressure is constantly applied to the colostomy, leakage may occur from the gap between the plug and the colostomy when the body is bent, and belts are used. There are drawbacks such as the need to wear a belt which is cumbersome, the belt being unstable or unusable depending on the position of the colostomy, and the method not being applicable if the stoma has large irregularities.

[Problem that the invention seeks to solve]

The purpose of the present invention is to solve the problems of the above-mentioned bagless colostomy device, such as foreign body sensation, necrosis, and
To obtain a colostomy appliance that does not cause rejection reactions due to foreign bodies, does not require removal surgery in abnormal cases, can be widely used with any type of stoma or stoma of stoma surgery method, and is lightweight and easy to wear. It is in.

(Means for Solving the Problems) According to the present invention, the above-mentioned object includes a fixing part having an opening formed to surround the colostomy, and a plug part capable of attaching a film to the fixing part. has an adhesive layer on one side and a male or female ring-shaped fitting arranged to surround the opening on the other side, and the stopper has a male or female ring-shaped fitting on the fixing part. This is achieved by having a female-type or male-type ring-shaped fitting body that can be fitted with the body and a protrusion portion that protrudes inward at the center.

(Function) In the colostomy appliance of the present invention, the fixing part is attached to the patient's body surface using the adhesive layer on one side in a positional relationship such that the opening of the fixing part and the patient's colostomy are approximately concentric. The stoma is fixed, the protruding part of the plug is inserted into the stoma, and the ring-shaped fitting body of the plug part and the ring-shaped fitting body of the fixed part are fitted, so that the stoma is closed with the plug part and ready for use. Once a certain amount of excrement has accumulated in the intestines, the plug can be removed from the fixed part again to allow the excrement to exit the body.
The plug is reinstalled after cleaning.

〔Example〕

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

FIG. 1 is a cross-sectional view showing the colostomy appliance according to the present invention with the fixing part and plug part separated, FIG. 2 is a plan view of the fixing part, and FIG.
The figure is a bottom view of the stopper, and FIG. 4 is a sectional view of the fixing part and the stopper combined and attached to a human body.

The fixing part 1 is a male-shaped ring placed on a laminate of a peeling paper 2, a flexible skin protection agent 3 having an adhesive function, and a polyethylene film 4 so as to surround an opening 5 provided in the center thereof. The ring-shaped fitting 6 is provided with a groove 7 at its base and a sealing member 8, such as an O-ring, along its outer periphery. The inner surface 9 of the ring-shaped fitting body 6 is formed so as to open slightly outward from the skin-contacting side.

The plug part 10 has a female ring-shaped fitting body 11 on the side facing the fixing part l, and this ring-shaped fitting body 11 is provided with a protrusion 12 on the inner periphery of its open end.

The stopper lO further has a protrusion 13 at its center that protrudes inward, and is provided with an operating knob 14 on its outer periphery. Although not shown in the figures, the plug part 10 is provided with a hole for venting gas that communicates between the inside and the outside, and depending on the situation, the hole can be filled with a deodorizing agent.

From the viewpoint of sealing properties, materials for the ring-shaped fitting body 6 and the main body 1o of the fixed part l include polyethylene, ethylene vinyl acetate, vinyl chloride, nylon, polypropylene, polycarbonate, polystyrene, ionomer resin, hard rubber, preferably polyethylene and ethylene. Vinyl acetate is suitable. The sealing member can be made of general sealing materials such as rubber, silicone rubber, and urethane rubber.

When installing this device, first peel off the release paper 2 of the fixing part 1, and use the adhesive function of the skin protectant 3 to position the colostomy 15 in the opening 5 of the patient, as shown in FIG. stick to the body. Next, the operation knob 14 of the executive 10
If you hold it in your hand and push the ring-shaped fitting body 11 over the ring-shaped fitting body 6 of the fixing part l,
The protrusion 12 on the inner circumferential surface of the female ring-shaped fitting body 11 is fitted into the male ring-shaped fitting body 6 17, and the two ring-shaped fitting bodies 6 and 11 are integrated, and the sealing member 8 is a ring-shaped fitting body. It is pressed against the inner surface of the shaped fitting body 11 to form a sealing function. Further, the protruding portion 13 of the trunk 1o is positioned to protrude into the artificial anus 15, and has the function of closing the artificial anus.

When there is drainage, since the artificial anus is blocked by the trunk 10, the excrement is temporarily stored in the intestine. If you want to discharge the excrement that has accumulated to a certain extent out of the body, hold the operating knob 15 of the trunk 10 and lift it up. Since it can be removed more easily, excrement can be expelled from the body through the colostomy.

In this case, if the inner surface 9 of the ring-shaped fitting body 6 of the fixing part 1 is opened outward in a conical shape, the discharge can be carried out smoothly.

In the above embodiment, a male ring-shaped fitting body was provided on the fixing part and a female ring-shaped fitting body was provided on the trunk. It is also possible to incorporate a male ring-shaped fitting into the trunk.

The fitting method of each ring-shaped fitting body of the fixed portion and the trunk is not limited to the above-mentioned embodiment, and various methods are possible. For example, as shown in FIG. 5, the ring-shaped fitting body 6 of the fixed part 1 has a bending piece 16 extending obliquely downward at the upper end and a rim 17 on the opposite side, and the ring-shaped fitting body 11 of the trunk 10 has a bending piece 16 extending diagonally downward. It has a concentric double wall 18.19 on its periphery, a rim 20 on the inside of the outer wall 18, and a ring-shaped fixing part 1 in a21 formed by the double wall 18.19 of the trunk 10. By pushing the fitting body 6, the restoring force of the bending piece 16,
With the interaction of the rim 17.20 the fixing part l and the trunk 10
and can be combined.

Further, as shown in FIG. 6, a ring-shaped fitting body 6 of the fixing part 1
The ring-shaped fitting body 11 of the trunk 10 has concentric double walls 22 and 23 at the periphery, and the width of the groove formed between the double walls is determined by the width of the ring-shaped fitting body of the fixed part. By making the thickness of the ring-shaped fitting body 6 slightly smaller than that of the groove 6 and pushing the ring-shaped fitting body 6 into this groove, the fixing part 1 and the trunk body 10 can be connected by the elasticity of the double walls 22 and 23.

In the above example, the entire trunk 10 including the protrusion 13 is made of the same material, but if only the protrusion 13 is made of a highly water-absorbing material, the protrusion 13 will be absorbed into the colostomy. Because it is located in the ostomy, it absorbs moisture from the excreta, swells, and comes into moderate pressure contact with the inner wall of the colostomy, further enhancing its sealing function. Highly absorbent materials include starch, mannan, sodium alginate, gum tragacanth, gum arabic, guar gum, gum karaya, gum hinnes, dextrin, glue, gelatin, natural water-soluble resins such as collagen, viscose, methylcellulose, ethylcellulose, hydroxyethylcellulose, Semi-synthetic water-soluble polymers such as carboxymethyl cellulose, soluble starch, dialdehyde starch, synthetic water-soluble polymers such as polyvinyl alcohol, polyvinylpyrrolidone, sodium polyacrylate, polyethylene oxide, polyacrylamide, and blends and modified products thereof. Super absorbent polymers such as, etc. can be used.

The stopper lO not only functions as a stopper, but also
It can also be used as an enema. FIG. 7 shows an example of this, in which a hole 24 is provided at the center of the stopper 10 through which the protrusion 13 passes, and the hole 24 is sealed with a hole 25 when in use.

When excrement is to be discharged, the plug part 10 is removed from the fixed part 1 in the same manner as described above. When administering an enema, the enema 25 is removed from the stopper 10, the tip of the tube connected to the enema liquid bag is inserted into the hole 24 of the stopper 10, and the enema liquid is poured.

The protruding part 13 of the plug part 10 can also be composed of two parts, a core member 26 and an adapter 27, as shown in FIG. The core material 26 is formed in a cylindrical shape, and a fitting groove 2 is formed in a part of the outer periphery.
8, the adapter 27 is formed into a bottomed cylindrical shape with an inner diameter into which the core material 26 can be inserted, and has a protrusion 29 on a part of its inner circumference that fits into the fitting groove 28 of the core material 26. . In use, when the adapter 27 is pushed onto the core material 26, the protrusions 27 are fitted 428 due to the elasticity of the adapter 27.
The core member 26 and the adapter 27 are fitted into the core member 26 and the adapter 27 are integrated to form the protrusion 13. If the protrusion is structured like this, it can be made soft by selecting an appropriate material for the adapter, and leakage can be reliably prevented by selecting the size of the adapter, and it can be made by simply preparing an appropriate number of adapter sizes. It is possible to accommodate various sizes of stomas, and only a few types of plug bodies are required.

When using this device, it is possible to drain the excrement accumulated in the colostomy out of the body by placing a container such as a drainage basin on the colostomy, but it is also possible to use the following devices: This is extremely advantageous.

FIG. 9 shows a partially modified fixing part according to the present invention,
The bag part connected to this fixing part is shown in a separated state, and the same parts of the fixing part are given the same reference numerals. In this fixed part l, in addition to the male ring-shaped fitting body 6 as the first coupling body, there is also a ring-shaped joint as a second coupling body disposed approximately concentrically on the sawing material 4 on the outside thereof. It has a face piece 30. The bag part 31 has a ring-shaped flange body 32 that can be coupled to the ring-shaped joint surface body 30 of the fixed part l, and an adhesive 34 is applied to one surface 33 of this flange body 32. A bag body 36 is fixed to the other surface 35, and a vinyl zipper 3 is attached to the upper end of the bag body 36.
7 is provided. 38 is an operating knob attached to the flange body 32.

As for the materials of the ring-shaped joint surface of the fixing part and the ring-shaped flange of the bag part, polyethylene, ethylene-vinyl acetate copolymer,
Vinyl chloride, nylon, polypropylene, preferably polyethylene, and ethylene-vinyl acetate co-merge are passed through.

When excrement accumulated in the colostomy is to be discharged from the body, the plug part 10 remains attached to the fixed part 1, and the adhesive 34 of the flange body 32 of the bag part 31 is applied to the ring-shaped joint surface of the fixed part 1. By pressing on the bag 30, the bag portion 31 is fixed to the fixing portion l as shown in FIG. In this state, as shown in FIG. 10, if you insert your hand through the opening of the vinyl zipper 37 at the upper end of the bag body 36 and remove the stopper lO from the fixing part 1, the excrement will flow into the bag body 36 from the colostomy 15. Ejected and stored. When the discharge is finished, the bag part 31 is removed from the fixed part 1, and the plug part 10 is washed and then attached to the fixed part 1 again, so that it can be reused.

The bag portion 31 can be used again if the excrement inside is disposed of and washed.

In the above example, the fixing part and the bag part are connected by adhesive, but it is also possible to use a fitting connection method such as between the fixing part and the plug part, or various other connection methods. Further, although the above-mentioned bag portion is used for discharging and storing excrement, it is of course also possible to use it for discharging enema liquid during enema.

〔Effect of the invention〕

The colostomy appliance of the present invention can be easily attached to the body by simply pasting it on the colostomy area due to the adhesive function of the fixing part, and even if there is an abnormality, it can be easily removed without the need for surgery. It can be removed and replaced, and it is very easy to put on as it does not require fixing devices such as belts. In addition, since it uses a mating method, the sealing function is perfect.
There is no need to worry about strenuous activity, and there is no foreign body sensation, necrosis, or rejection because there are no parts to be constructed inside the body.
It can solve all the drawbacks of conventional bagless braces. Furthermore, since the protruding part of the trunk is inserted into the colostomy, it has the effect of preventing stenosis of the colostomy, and the trunk can also be used to perform various functions such as degassing and deodorizing. It is possible to administer an enema without using any special equipment, and even if leakage occurs from the protruding part, it is double-sealed by the fitting of the trunk, so there is no risk of leakage to the outside, and it can be used with peace of mind. There is no need to apply excessive force to the intestinal wall to expand the intestine.
