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.

The base material of the skin member conventionally used for the device for treating body wastes includes a nonwoven fabric type, a film type and a foam type.
There is one. The non-woven fabric type is a non-woven fabric made of polyethylene, polypropylene, rayon, polyester, or a blend of these materials. The non-woven fabric type has good air permeability, good water vapor permeability, and can be applied to the skin even when attached to the body. It has the advantage that it does not hinder breathing and does not suppress sweating. However, the conventionally used non-woven fabric does not follow the movement of the body because it does not have elasticity, causing a sense of tension and a sense of incongruity. The second film type uses a film of polyethylene, vinyl chloride, urethane or the like. However, apart from urethane, it has poor elasticity, has almost no air permeability, and has a large discomfort when pasted, so that sweat comes in contact with it. It accumulates between the skin member and the skin, causing rash or peeling of the skin contact member. Urethane films with a thickness of about 20 to 100 μm have high elasticity and do not cause discomfort even when pasted, but because the film is thin and soft, it is difficult to paste, and it tends to cause wrinkles and leaks from it There is a risk of causing
Moreover breathable urethane film is much worse than the nonwoven fabric, the water vapor permeability may be 200g / m ^2/24 hours / 40 ° C. /
Since the humidity is around 80% relative humidity, sweat may accumulate between the film and the skin when the humidity is high or when sweating is excessive. The third foam type comprises a skin member made of a foam such as polybutadiene, polyethylene, or ethylene / vinyl acetate copolymer. These materials are stretchy and have a waist, so they are easy to stick, but because they use closed-cell foam to prevent leakage, they do not breathe, sweat easily collects during use, and cause peeling and rash Become.

[Problems to be solved by the invention]

An object of the present invention is to provide a body excrement disposal device having a skin member that has a moderate waist, is easy to attach, has elasticity, does not cause discomfort during use, and is highly breathable.

[Means for solving the problem]

In order to achieve the above-mentioned object, in the device for treating body excrement of the present invention, the skin member is formed of a nonwoven fabric made of a thermoplastic elastomer.

As the thermoplastic elastomer used in the present invention, polyurethane-based, polyolefin-based, polystyrene-based, polyester-based, polyamide-based, vinyl chloride-based and the like,
Particularly, polyurethane-based and polyolefin-based materials are preferable from the viewpoint of ease of heat sealing and high-frequency sealing at the time of bonding with the pouch body. Polyolefins include polyethylene, polypropylene, ethylene-vinyl acetate copolymer, chlorinated polyethylene, ethylene ethyl acrylate, ethylene
Examples include methyl acrylate.

As a method for producing a nonwoven fabric, a method such as so-called spun bonding, flash spinning, or melt blowing is used, which is a direct spinning method in which a sheet is formed at the same time as forming a yarn from the above resin.

The nonwoven fabric can be formed into a plurality of phases by using, for example, two types of thermoplastic elastomers, for example, a polyurethane type and a polyolefin type, instead of one type of thermoplastic elastomer.

Basis weight of the nonwoven fabric, 25~200g / m ^2, preferably 100 g / m ²
The elongation is good, the elongation is preferably 50 to 800%, preferably 100%, and the modulus is advantageously 0.01 to 0.30 kg / mm ² . The air permeability of the nonwoven fabric may be 1 cc / cm ² / sec or more.

[Action]

In the device for treating body waste of the present invention, the skin member is formed of a non-woven fabric made of a thermoplastic elastomer, and the non-woven fabric has a moderate waist, elasticity, and breathability, so that the non-woven fabric is easily attached to the skin. After sticking, it expands and contracts following body movements well, and is well radiated to the outside when sweating occurs.

〔Example〕

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

1 and 2 show a longitudinal side view and a rear view, respectively, of an embodiment of the present invention, wherein 1 is a disk-shaped skin member, and a nonwoven fabric (for example, Kanebo) formed from a thermoplastic polyurethane elastomer by a spunbond method. The product name is "Espansione". This non-woven fabric has a basis weight of 10
It has characteristics of 0 g / m ² , elongation in the transverse direction of 300%, elongation in the longitudinal direction of 400%, modulus of 0.05 kg / mm ² , and air permeability of 25 cc / cm ² / sec.

The skin member 1 has an adhesive 2 applied to the skin side, has an opening 3 at the center, and has an opening of the same size as the opening 3 of the skin member 1 on the side opposite to the skin side. A seal reinforcing sheet 5 made of a polyethylene film to which an adhesive 4 is attached is attached.

Reference numeral 6 denotes a pouch body formed in a bag shape from a three-layer film of, for example, polyethylene / polyvinyl chloride / polyethylene, and has an opening 7 serving as a passage for discharged matter.
Are fixed to the seal reinforcing sheet 5 by heat welding. It is preferable that the pouch body 6 is fixed to the skin member 1 in such a direction that its longitudinal direction, that is, the vertical direction coincides with the direction in which the skin member 1 extends greatly.

FIG. 3 is an enlarged view of an embodiment in which the skin members are formed in a multi-layer type, and the same reference numerals are given to the same parts as those in FIGS. 1 and 2. The skin member 1 is formed by laminating a nonwoven fabric layer 9 made of a polyurethane elastomer on the skin side and a nonwoven fabric layer 10 made of an ethylene / vinyl acetate copolymer on the pouch body 6 side, and is integrally formed. The adhesive 2 is applied to the surface of the nonwoven fabric layer 9, and the pouch body 6 made of polyethylene / polyvinylidene chloride / polyethylene is heat-welded to the surface of the nonwoven fabric layer 10. The material of the non-woven fabric on the skin side and the pouch body side is changed by forming a two-layer type in this way, the non-woven fabric having the properties required for the skin side on the skin side, and the pouch body on the pouch body side Non-woven fabrics that can be welded to each other can be selected, and it is possible to solve the problem that each material was limited in welding conventionally between the skin-contacting member and the pouch body.

The basis weight of the nonwoven fabric is related to the physical properties of the waist.If it is too small, it will be too soft and difficult to stick, and the air permeability will be good, but the welding between the skinning member and the pouch body will be incomplete and will be discharged through the skinning member There is a possibility of things leaking,
On the other hand, if it is too large, it becomes too hard to adhere similarly, does not follow body movement well, and has poor air permeability, which adversely affects the skin.

If the elongation of the nonwoven fabric is small, it will cause discomfort when pasted, but the abdomen, perineum, and buttocks are 30 to 80%, so it is not necessary to use a very large value, and it is advantageous to select the above value range It is.

The modulus of the nonwoven fabric is preferably in the above-mentioned range in that the nonwoven fabric must have appropriate elasticity so that the nonwoven fabric can be stretched and returned at the same time.

〔The invention's effect〕

According to the present invention, by using a non-woven fabric made of a thermoplastic elastomer for the skin member, it is possible to form a skin member having a moderate waist, elasticity, and air permeability, and thus a complicated structure is obtained. It is easy to stick to uneven human body surface, does not disturb the skin well, does not interfere with skin respiration and sweating, keeps the skin in a normal physiological state, and has a skin contact member and pouch body Can be combined to have the strength and liquid tightness required for a body waste treatment appliance.
