BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ostomy bag which is attached to an opening formed on the surface of a living body and accommodates the discharge discharged from the living body through the opening.

[0002]

2. Description of the Related Art Generally, an ostomy bag is attached to an opening formed or created on the surface of a living body due to various diseases, and wastes discharged from the living body through the opening are treated. In this ostomy bag, it is most preferable that a bag body is connected to the side opposite to the skin side of the skin part that is stuck to the periphery of the opening of the living body, and the discharge from the opening is stored in the bag body. It is a general structure.

[0003] Since the bag body of the ostomy bag temporarily stores the excrement, it does not leak the excrement and odor to the outside, has strength enough not to be broken by external pressure, and has high sealing strength. It must satisfy many requirements, such as that it does not give a feeling of strangeness to the skin, that it is supple, and that it does not generate noise when worn. Conventionally, the bag body of this ostomy bag is mainly made of polyethylene, polyvinyl chloride, chlorinated polyethylene, vinylidene chloride,
Soft and thick, such as ethylene vinyl acetate copolymer
It is formed of a plastic film of about 500 μm.

[0004] Considering the case where excrement enters the bag, the plastic film is transparent or translucent in the conventional one, so that the place where the excrement is attached can be seen through, giving a sense of uncleanness, and the handling becomes painful. In particular, in the case of contact with a third party, the mental distress of the party is great because of the uncleanness given to the third party. Various methods have been proposed to solve this problem. One is to overlay an opaque non-woven fabric on the outside of the bag, but it is necessary to weld the outer periphery of the non-woven fabric and the plastic film, the type of the non-woven fabric is limited, and the elongation of the non-woven fabric and the plastic film are different. After sealing the outer periphery, the unsealed central portion is stretched to cause floating, and the apparent appearance is poor. As another method, there is a method of coloring or printing on a plastic film, but there are many olefin-based plastic films having various functions such as easy heat welding, flexibility and high gas barrier properties, and olefin-based printing inks. However, it does not adhere well, requires special treatment such as corona discharge, increases the cost, and the color of the plastic film and the color of the excrement mix to give a more uncomfortable feeling. There is a problem that the gas barrier property is lowered. There is also a method of covering the bag with a cloth bag, but it is difficult to attach because there is no part to fix the bag,
The feeling of wearing is also bad because only the thickness of the bag increases.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an ostomy bag that makes excrement invisible and that has a good fit and is easy to manufacture.

[0006]

In order to achieve the above-mentioned object, in the present invention, a skin portion having an opening and an adhesive layer on the skin side is connected to the skin portion on the side opposite to the skin side. A bag made of a plastic film, wherein the outer surface of the bag opposite to the skin side of the plastic film is subjected to flocking.

[0007]

According to the present invention, since the short fibers are formed in close contact with the surface of the plastic film by flocking the outer surface of the plastic film forming the bag, the light applied to the film is scattered. Since the contents of the bag do not show through, the rubbing between the films becomes the rubbing between the fibers, so no sound is generated, and the bag is also made by the same simple manufacturing process as before. is there.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIGS. 1 and 2 are a longitudinal sectional view and a front view, respectively, of an embodiment of the present invention. The ostomy bag is formed from a skin portion 1 and a bag body 2, and the skin portion 1 is made of a flexible thin circular sheet made of, for example, plastic, and has an adhesive layer on one side, that is, the skin side. 3 and an opening 4 in the center. The bag 2 includes a plastic film 5 on the inner side, that is, the skin portion 1 side, and a plastic film 6 on the outer side, that is, the opposite side to the skin portion 1, and the plastic film 5 on the skin side corresponds to the opening 4 of the skin portion 1. The peripheral portion 8 of the opening 7 is welded around the opening 4 of the skin portion 1 and the outer periphery 9 of the inner plastic film 5.
And the outer periphery 10 of the outer plastic film 6 are thermally welded to each other, and the skin contact portion 1 and the bag 2 are integrated. The outer surface of the plastic film forming the bag 2, particularly the outer surface of the outer film 6, is subjected to flocking 11.

As the skin portion 1, a film made of polyethylene, chlorinated polyethylene, ethylene vinyl acetate copolymer, vinylidene chloride, polypropylene, polyurethane, rubber hydrochloride, or the like, or a composite film having these as a surface layer can be used. The pressure-sensitive adhesive layer 3 is referred to as an acrylic pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, or a skin protective agent in which pectin, karaya gum, shikonin, or the like is mixed into the pressure-sensitive adhesive or polyisobutylene rubber. An adhesive can be used.

As the plastic films 5 and 6 of the bag body, excrement is stored so as not to leak, and in order not to leak malodor, the tear strength is high, the sealing strength is high, the flexibility is high, and the water vapor permeability is low. A material that has excellent gas barrier properties and is capable of flocking is preferable. Examples of usable plastic films include EVA / PDVC / EV
A, EVA / PDVC / PE, PVC, PE / PVDC
/ PE, PE, PVDC, EVA / EVOH / EVA, etc., and preferred are EVA / PVDC / EVA, P
VC. Materials used for flocking, so-called piles, include nylon, rayon, polypropylene, polyester, etc.
Polyester is preferred. The pile length is 0.2-6m
m, preferably 0.2 to 1 mm, and a thickness of 0.75 to 30 denier, preferably 0.75 to 3 denier. The color is free, but white or flesh color is preferred. Of course, opacity can also be increased by using colored piles. Epoxy, urethane, and acrylic adhesives can be used as the adhesive used for the flocking process, but urethane is preferable.As a method of applying the adhesive, a spray gun, a brush, a roller, a print mold, There is a doctor knife type and the like, but a doctor knife type is suitable. There are mechanical and electrostatic methods for flocking.
The electrostatic method is suitable for obtaining uniform and dense flocking. In the electrostatic method, an adhesive is applied to the surface of a plastic film, and a pile is formed using an electrostatic field on the adhesive. Methods for causing the pile to reach the film surface include a down type in which the pile is shaken down from above, a map type in which the pile flies upward from the bottom, and a side type. Thereafter, the film is transferred to a drying step, and is dried by far infrared rays or hot air to solidify the adhesive and fix the pile on the film surface. When the anchoring property of the flocking is low, it is advantageous to apply the adhesive after applying the primer to the film surface.

The ostomy bag according to the present invention can be manufactured using exactly the same manufacturing process as in the past, simply by flocking the plastic film outside the bag body.

[0013]

According to the present invention, since the outer surface of the plastic film forming the bag is implanted on the outer surface opposite to the skin side, even if the bag is irradiated with light from the outside,
The light is scattered by the short fibers that are provided close to the surface, so that the contents do not show through, and do not cause discomfort to the person or a third party, and the bag moves. Even when the films come into contact with each other, the fibers come into contact with each other, so that no sound is produced, the feeling is good, and the production can be carried out in almost the same steps as before.
