Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a body excrement treatment method for storing various solids and liquids discharged from the body in a bag-like object from an opening of the body. Use an orthosis.

[Conventional technology]

Due to illness, he underwent open surgery, including a colostomy, an artificial bladder, and a kidney.
Patients with openings in the stomach, intestines, etc., incontinent patients, patients who require drains after surgery, or physically disabled patients may voluntarily remove body waste, such as feces, urine, secretions, etc. Since body excreta cannot be controlled or treated by human body, a bag-shaped device for treating body excreta is fixed to the opening of the human body so that the excreta is automatically stored in the bag. This orthosis is generally formed from a bag called a pouch and a sheet-like material called a skin contact member that is bonded to the pouch. The structure is such that the pouch is fixed and the waste is stored in the pouch through the opening of the skin-contacting member.

As mentioned above, the skin-contacting member of this body excrement treatment equipment adheres to the skin with its adhesive, so if the skin-contacting member is not breathable, sweat will accumulate between it and the skin. This can cause rashes, so it has been proposed to use a nonwoven fabric with excellent breathability as a skin contact member.

Its structure is generally as shown in Fig. 4a%b and c, and in Fig. 4a, the nonwoven heavy skin member 1 and the pouch main body 2 are arranged so that their respective openings 3.4 overlap. A water-absorbing skin protectant 6 that is directly fixed to the peripheral edge of the opening 3.4 and has an opening 5 is inserted under the skin contact member 1 to remove the skin contact member 1.
The pouch is attached to the skin using an adhesive 7 applied to the seed coat side of the pouch, but the sealing strength is weak because the nonwoven layered skin member 1 and the pouch body 2 are directly welded, and the nonwoven fabric in the sealing part There is a high possibility of leakage of emissions through the fourth
In the figure, the nonwoven layered skin member 1 and the pouch body 2 are not directly connected, but an adhesive plastic film 8 is inserted between the two, but the ventilation area is reduced due to the adhesive plastic film 8. However, there are disadvantages in that the number of manufacturing steps increases, the cost of materials increases, and the flexibility of the nonwoven layered skin member 1 is lost. The one shown in FIG. 4C is one in which the non-woven heavy skin member 1 and the pouch main body 2 are directly fixed to each other, and has the same sealing problem as that shown in FIG. 4A.

[Problems to be Solved by the Invention] It is an object of the present invention to provide a skin-contact member that is sufficiently flexible, follows body movements, has high welding strength with the pouch body, and has good air permeability. The object of the present invention is to obtain an equipment for waste disposal.

[Means to solve the problem]

In order to achieve the above-mentioned object, the device for treating body excreta of the present invention includes a pouch body having an opening on one side;
A skin contact member made of an olefin nonwoven fabric and having an opening corresponding to the opening of the pouch body, and each peripheral edge of the opening of the pouch body and the opening of the skin contact member are welded to each other via an olefin nonwoven fabric sheet. , an adhesive is provided on the side of the skin contact member opposite to the side welded to the pouch body.

Examples of olefin-based nonwoven fabrics that form the skin-contact member include those rich in polyethylene, polypropylene, and ethylene/vinyl acetate copolymers, as well as those with a core made of polyester, polypropylene, etc., and the periphery surrounded by polyethylene, ethylene/vinyl acetate copolymers, etc. Fibers that are combined, surrounded by polypropylene, etc., conjugate type composite fibers, etc. can be used.

The elongation of this nonwoven fabric is 20% to 300%, and the basis weight is 30%.
g/m' to 200 g/m", especially 30 g/m"
A range of 130 g/m'' is preferred.

The nonwoven fabric sheet inserted between the pouch body and the skin contact member is preferably the same type of nonwoven fabric as the nonwoven fabric forming the skin contact member.

[Effect]

In the device for treating body excreta of the present invention, since the skin contact member is made of olefin-based nonwoven fabric, when the skin contact member is applied to the skin with its adhesive, the skin contact member also moves in accordance with the movement of the body. It blends in well, and the welding of the pouch body, nonwoven fabric sheet, and skin contact member increases the breaking strength of the welded portion and blocks capillary action in the skin contact material. Furthermore, the seal part does not become hard.

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

Figures 1a and 1b are longitudinal sectional side views of an embodiment of the present invention, respectively;
11 is a disc-shaped skin contact member, which is made of polyethylene nonwoven fabric, has almost no elongation, and has a basis weight of 50.
g/m”s Airflow rate 21cc/cm’/se
It has the characteristics shown in c. An adhesive 12 is applied to the seed coat side, and an opening 13 is provided in the center.

14 is a bag-shaped pouch body made of a three-layer structure of polyethylene/polyvinylidene chloride/polyethylene (manufactured by Fukkasei Co., Ltd., trade name "Varialon"), and has an opening 15 for passage of waste; A donut-shaped nonwoven fabric sheet with a width of, for example, 15 cm, made of the same nonwoven fabric as the member 11 and having the same opening 17 as the opening 13 of the skin contact member 1.1, the opening 13 of the skin contact member, the opening 17 of the nonwoven fabric sheet 16, The peripheral edges of the opening 15 of the pouch body 14 are fixed to each other by heat welding with the nonwoven fabric sheet 16 in the middle.

As the non-woven fabric for the skin-contacting member, a conjugate type fiber made from ``rEs fiber'' manufactured by Ube Industries, Ltd. can also be used.

Polyethylene, ethylene/vinyl acetate copolymer, chlorinated polyethylene, etc. can be used for the pouch body, and it is preferable that the material involved in welding with the skin member is polyethylene or ethylene/vinyl acetate copolymer. .

FIG. 2 shows another embodiment, in which parts equivalent to those in FIG. 1 are given the same reference numerals. In this example, the nonwoven fabric sheet 16 is formed to have the same external shape as the pouch body 14, and the outer edge 18 is formed to have the same shape as the pouch body 14.
It is welded to the outer edge 19 of 4 and becomes an integral part, and when it is applied to the skin, the non-woven fabric 16 comes into contact with the skin, giving a good feel.

In the case of the embodiments shown in FIGS. 1 and 2, the melted resin of the inserted nonwoven fabric sheet 16 enters into the fibrous structure of the skin contact member 11 and is integrated or fills the gap in the fibrous structure, and the welded part is bonded. In addition to increasing the breaking strength of the member itself, it also blocks capillary action in the skin-contacting member to enhance the effect of preventing leakage of waste from the skin-contacting member.

FIG. 3 shows an example of a welding pattern between the skin contact member and the main body, in which a plurality of weld rings 20, 21, and 22 are formed concentrically with the opening 13 of the skin contact member. The width d of this welding ring is preferably 2a or less. The bottom surface of the cherry bark side of the welding ring will rise slightly due to welding, but if the width is too wide, the adhesive strength will weaken and it will easily peel off (which may lead to leakage).By making this width 2ms or less, the left and right adhesive surfaces 23 .24, 25, 26 adhesive strength ensures secure retention and no leakage.

〔Effect of the invention〕

According to the present invention, since the skin-contacting member is formed of an olefin-based nonwoven fabric, the skin-contacting member faithfully follows the movement of the body, blends well with the skin, and does not cause any discomfort, and therefore does not cause stress on the skin. Even if you wear it for a long time, it will not obstruct skin breathing or prevent perspiration, so your skin will always maintain a normal physiological state. The welding strength between the pouch and the main body is extremely high, so there is no risk of leakage during use.
Furthermore, the manufacturing process is quite simple, and since olefin-based nonwoven fabrics can be heat-sealed, sealing is easy and manufacturing costs are low.
