Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to treatment of in-vivo excretion for accommodating various solids and liquids excreted from the body into a bag-like object through an opening of the body for treatment. For equipment.

[Conventional technology]

Patients who undergo opening surgery due to illness and have openings such as colostomy, artificial bladder, renal fistula, gastrostomy fistula, enterostomy, incontinence, patients who need drain after surgery, or persons with physical disabilities Can not control or treat stool, urine, secretion fluid, etc. on their own volition, so a body waste treatment device consisting of a bag-shaped object is fixed to the opening of the human body, and It is stored in a bag. The brace is generally formed from a bag called a pouch and a sheet-like material called an insulting member joined to the pouch, and is attached to the opening of the body with an adhesive provided on the side opposite to the side where the pouch is joined to the insulting member. It is configured to be fixed and the discharged matter is stored in the pouch through the opening of the skin contact member.

As described above, the skin contact member of the device for treating body waste is fixed to the skin with the adhesive, and if the skin contact member has no air permeability, sweat accumulates between the skin and the skin. Therefore, it has been proposed to use a non-woven fabric having excellent air permeability as a skin contact member. The structure is generally as shown in FIGS. 4a, b and c. In the case of FIG. 4a, the nonwoven fabric skin member 1 and the pouch body 2 are arranged side by side so that the openings 3, 4 overlap. A water-absorbing skin protective agent 6 having an opening 5 is directly fixed to the peripheral portion of the skin 3 and 4 and inserted under the skin 1 with the adhesive 7 applied to the skin side of the skin 1. Although it is to be worn on the skin, the seal strength is weak because the nonwoven fabric skin member 1 and the pouch body 2 are directly welded, and the possibility of leakage of the discharged matter through the nonwoven fabric of the seal portion is large.
FIG. 4b shows a non-woven fabric skin member 1 and a pouch body 2 which are not directly connected to each other, but have an adhesive plastic film 8 between them.
, But the adhesive plastic film 8
Therefore, there is a drawback that the ventilation area is reduced, the number of manufacturing steps is increased, the material cost is increased, and the flexibility of the nonwoven fabric skin member 1 is lost. FIG. 4C shows a non-woven fabric skin member 1 and the pouch body 2 directly fixed, and has the same sealing problem as FIG. 4A.

[Problems to be solved by the invention]

It is an object of the present invention to provide a body excrement disposal device in which a skin contact member follows body movement with sufficient flexibility, has high welding strength to a pouch body, and has good air permeability. .

[Means for solving the problem]

In order to achieve the above object, in the device for treating body waste of the present invention, a pouch body having an opening on one side, and a skin member having an opening corresponding to the opening of the pouch body made of an olefin-based nonwoven fabric. And the peripheral edges of the opening of the pouch body and the opening of the skin member are welded to each other via an olefin-based nonwoven fabric sheet, and an adhesive is provided on the side of the skin member opposite to the side welded to the pouch body. It is.

As an olefin-based nonwoven fabric forming a skin member,
For example, polyethylene, polypropylene, ethylene-vinyl acetate copolymer rich besides polyester,
Fibers having a core of polypropylene or the like and surrounded by polyethylene, ethylene / vinyl acetate copolymer, polypropylene or the like, conjugate type composite fibers, or the like can be used. The elongation of this non-woven fabric is 20% ~ 300%, the basis weight is 30g
/ m ² ~200g / m ^2, in particular in the range of 30g / m ² ~130g / m ² is preferred.

As the nonwoven fabric sheet inserted between the pouch body and the skin member, the same type of nonwoven fabric forming the skin member is preferable.

[Action]

In the body waste treatment device of the present invention, the skin member is made of an olefin-based nonwoven fabric, so that when the skin member is attached to the skin with the adhesive, the skin member also corresponds to the movement of the body. The welding between the pouch body, the nonwoven fabric sheet and the skin member improves the breaking strength of the welded portion and blocks the capillary phenomenon of the skin member. Further, the sealing member does not become hard.

〔Example〕

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

1a and 1b show a longitudinal side view and a rear view, respectively, of an embodiment of the present invention. Reference numeral 11 denotes a disk-shaped skinning member, which is formed of polyethylene non-woven fabric, has almost no elongation, and has a basis weight of 50.
It has a characteristic of g / m ² and a ventilation rate of 21 cc / cm ² / sec. An adhesive 12 is applied to the skin side, and an opening 13 is provided at the center.

Reference numeral 14 denotes a pouch body formed of a three-layer structure of polyethylene / polyvinylidene chloride / polyethylene (trade name "Varilon" manufactured by Asahi Kasei Corporation) and having an opening 15 serving as a discharge passage, and 16 a skin material. The width having the same opening 17 as the opening 13 of the skinning member 11 made of the same nonwoven fabric as 11 is 15 mm, for example.
In the donut-shaped nonwoven fabric sheet, the peripheral edges of the opening 13 of the skin contact member, the opening 17 of the nonwoven fabric sheet 16, and the opening 15 of the pouch body 14 are mutually fixed by heat welding with the nonwoven fabric sheet 16 in the middle.

As the non-woven fabric of the skin member, a conjugate type fiber formed by Ube Industries, Ltd. under the trade name “ES fiber” can be used.

As the pouch body, polyethylene, ethylene / vinyl acetate copolymer, chlorinated polyethylene, or the like can be used, and the material involved in welding with the skin member is preferably polyethylene, ethylene / vinyl acetate copolymer. .

FIG. 2 shows another embodiment, and the same reference numerals are given to the same parts as those in FIG. In this example, the nonwoven sheet 16 is the pouch body
The outer shape is formed to be the same as the outer shape, and the outer edge 18 is welded and integrated with the outer edge 19 of the pouch body 14, so that when applied to the skin, the nonwoven fabric sheet 16 comes into contact with the skin, so that a good feel can be obtained.

In the case of the embodiment shown in FIGS. 1 and 2, the melted resin of the inserted nonwoven fabric sheet 16 enters the fiber structure of the skin member 11 and embeds the gap of the integrated or fiber structure, and the skin of the welded portion is formed. In addition to increasing the breaking strength of the member itself, the effect of blocking the capillary phenomenon of the skin member and preventing leakage of the discharge from the skin member is enhanced.

FIG. 3 shows an example of a welding pattern between the skin member and the pouch body, and a plurality of welding rings concentric with the opening 13 of the skin member.
20, 21, 22 are formed. The width d of this welding ring is
It is preferably set to 2 mm or less. Although the bottom surface of the welding ring is slightly lifted by welding on the skin side, if the width is wide, the adhesive strength is weakened and the peeling is likely to occur, which may lead to leakage. By setting the width to 2 mm or less, the adhesive surfaces 23, 24, 25, and 26 on the left and right sides are securely held by the adhesive force, and no leakage occurs.

〔The invention's effect〕

According to the present invention, since the skin member is formed of an olefin-based nonwoven fabric, the skin member faithfully follows the movement of the body, adapts well to the skin and does not cause discomfort, and therefore stresses the skin. It does not give and does not inhibit skin respiration or prevent sweating even when worn for a long time, so the skin always keeps a normal physiological state, and the degree of sealing between skin and skin, skin The welding strength between the pouch and the body of the pouch is extremely high, so there is no danger of leakage during use, and the manufacturing process is very simple. It will be cheaper.
