JPS596807Y2 - Molded absorbent pad for colostomy appliance - Google Patents

Description

[Detailed description of the invention] The present invention relates to an absorbent pad used for a colostomy appliance.
More specifically, the present invention relates to a precept-type absorbent pad that is used by being incorporated into various cup-shaped appliances.

A colostomy is generally a surgical procedure performed to remove the large intestine due to causes such as rectal cancer, ulcerative colitis, or Hirschsprung's disease.
An excretory hole (hereinafter referred to as a stoma) constructed in the abdominal wall as an outlet for excreting all of the contents of the colon.

Such stomas do not have an anal sphincter muscle, and intestinal mucosal prolapse phenomenon, in which the intestinal mucosa protrudes from the stoma due to intestinal oscillation, is often observed.

Similarly, since there is no anal sphincter, feces and intestinal fluids are excreted involuntarily and irregularly.

Therefore, it is difficult to keep the area around the stoma clean at all times, and dermatitis, redness, erosion, etc. occur around the stoma.

People with a colostomy use devices such as a fecal bag called a pack or a cup-shaped urinal container to dispose of their bowel movements by attaching them to their stomas. It is used by being incorporated into a device that has a specific structure, which prevents the intestinal mucosal prolapse phenomenon to a considerable extent, and also has excellent absorption characteristics and prevents dermatitis around the stoma. It is something that can be prevented.

That is, the present invention is an absorbent pad that is used by being incorporated into a cup-shaped ostomy appliance, and the center part of the pad is convex, the outer periphery is concave along the inner periphery of the appliance, and the outer periphery is convex. This is a brim-shaped absorbent pad for an ostomy appliance, characterized in that it is brim-shaped at approximately the same height as the central portion.

In other words, the hollow-shaped absorbent pad of the present invention has a convex central part, and the convex central part lightly contacts the prolapsed intestinal mucosa, thereby preventing intestinal mucosa prolapse, and at the same time, this convex central part lightly contacts the prolapsed intestinal mucosa. The part contacts the stoma and quickly absorbs excretory fluid discharged from the stoma, keeping the area around the stoma relatively dry at all times.

In addition, the hollow-shaped absorbent pad of the present invention has an outer periphery concavely shaped to follow the shape of the cup, so it can be properly incorporated into the cup, and the cup itself is less likely to get dirty and can be easily replaced.

Fig. 1 is a perspective view showing a state in which a certain type of absorbent pad 1 of the present invention is inserted into a cup-shaped colostomy appliance 5, and Fig.
The figure shows a cross-sectional view of a certain type of absorbent pad 1 inserted into the appliance 5, and FIG. 3 is a cross-sectional view showing another example of the molded absorbent pad of the present invention.

The convex part of the central part 2 of the pad is appropriately determined according to the shape and size of the stoma, and the concavity of the outer peripheral part 3 is determined according to the shape and depth of the cup.

The height of the outer peripheral edge part 4 is approximately the same as the height of the central part 2, and is shaped like a brim so as to be in contact with the edge of the brace 5.

Pads are made from absorbent materials such as paper and nonwoven fabrics, and are composite materials using pulp or other absorbent powders such as alkali metal salts of alginic acid, cellulose derivatives, starch polyacrylonitrile graft copolymers, etc. as absorbent layers. can be suitably used.

In these composite materials, a disinfectant or a deodorizer can be used together with the absorbent material, and a moldable material may be combined to improve the moldability.

In a certain type of absorbent pad of the present invention constructed in this way, the central part of the pad corresponding to the stoma is shaped in a convex shape to prevent intestinal mucosal prolapse.

As mentioned earlier, the stoma does not have an anal sphincter;
A phenomenon in which the intestinal mucosa prolapses from the stoma occurs due to causes such as intestinal oscillation.

However, it has been found that this phenomenon can be prevented by applying pressure to the extent of light contact at the very beginning of escape.

Therefore, by arranging the central part of the pad to be convex and in contact with the prolapsed intestine as in the present invention, prolapse of the intestinal mucosa can be prevented to a considerable extent.

At the same time, since the convex central portion 2 is in contact with the stoma, excrement from the stoma can be quickly absorbed and the area around the stoma can be kept clean.

In addition, the outer periphery 3 of the pad of the present invention has a concave shape according to the shape of the cup-shaped device to be used, and the outer periphery 4 is molded into a brim shape at approximately the same height as the central portion 2, so that it does not fit into the cup. It can be set accurately and easily, it is easy to replace, and there is little chance of soiling the cup itself or leakage of excrement from the cup.
