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.

Materials used for the pouch include polyethylene, a composite film made of polyethylene / polyvinylidene chloride / polyethylene, polyvinylidene chloride, polyvinyl chloride, and the like. Vinyl (hereinafter referred to as PVC) is preferred. The first reason is that when using a soft PVC film, there is no sound when the pouch is used on the skin, the second is that the PVC film is soft and has a good feeling, and the third is that the PVC is made of olefin. The fact is that the welding process is more stable.

There are a number of deficiencies that remain unsolved in the function of the skin graft used to secure the pouch to the skin. First, conventional skin members lack air permeability, thereby inhibiting skin respiration and preventing perspiration, and in some cases, sweat builds up between the skin member and the skin. As a result, the skin may be destroyed in a normal physiological state, causing rash or peeling of the skin-contacting member. The second is that when a conventional skin contact member is applied to the skin, it causes a sense of incongruity and always feels stiff during use, which causes stress on the skin and induces rash due to physical stimulation. However, the cause is that the skin contact member itself does not stretch, or even if it stretches, it is smaller than the skin stretch.
Third, there is no flat place on the human body, the abdomen is the same, and wrinkles are present. It is not uncommon to stick it so that it doesn't wrinkle.

As a skin contact member of a conventional artificial bladder orthosis, there is a PVC sheet coated with an adhesive, which can be directly welded to a PVC pouch and has good workability, but has no air permeability, and the thickness of the PVC sheet is There is not enough elongation because it is around 200 μm,
Gives discomfort and physical stress to the skin during use. Also, sticking this PVC sheet so as not to cause wrinkles is a very troublesome operation, and it is more difficult to stick the sheet if the sheet is made thinner in order to improve the familiarity with the skin. Further, a skin member in which an adhesive is applied to a stretchable foam sheet (thickness: 0.5 to 1 mm) has been conventionally used. Since the foam is not made of PVC, it cannot be welded directly to the pouch material.Therefore, insert a PVC label consisting of a PVC sheet and an adhesive between the pouch and the skin material, and weld the PVC sheet and the pouch. Then, the adhesive of the PVC label is attached to the foam sheet of the skin member, and the adhesive of the skin member is applied to the skin.
This skin contact member has a relatively small amount of elasticity, so that there is relatively little discomfort during use and stress applied to the skin, and since it has a waist, it can be easily applied without causing wrinkles when applied to the skin. However, because it requires a PVC label, its workability is poor, and above all, its breathability is greatly restricted, inhibiting skin breathing and sweating,
Factors of rash and perspiration cause the adhesive to weaken and cause leakage.

Further, in order to solve the problem of air permeability of the skin member, a non-woven sheet is used for the skin member, and the pouch is used to ensure the connection between the non-woven sheet and the pouch and prevent leakage of the discharge through the non-woven sheet. An annular mounting ring has been proposed, and the mounting ring and the nonwoven fabric sheet are combined. This method solves the problem of air permeability because the nonwoven sheet is microporous.However, since the nonwoven sheet used is not stretched, there is little adaptation of the skin material to the skin. Also have problems that are complicated.

[Problems to be solved by the invention]

The object of the present invention is to use a PVC pouch having various advantages, it is breathable, does not inhibit skin respiration, sweating, stretches, does not give stress to the skin, and does not wrinkle when pasted An object of the present invention is to provide a device for treating bodily discharges which is provided with such an easy-to-apply skin contact member and is easy to manufacture.

[Means for solving the problem]

In order to achieve the above object, in the device for treating body excrement of the present invention, a pouch body made of a polyvinyl chloride film and having an opening on one side, and at least a ring-shaped body fixed around the opening of the pouch body. 100% in one direction
A skin-forming member based on a non-woven fabric mainly composed of polyurethane fiber or polyester fiber, which has a modulus at the time of extension of 70 g / cm to 1000 g / cm and a modulus at the time of 50% extension of 20 g / cm to 1000 g / cm. And an adhesive is provided on the side of the skin-contacting member opposite to the surface to be fixed to the pouch body.

The nonwoven fabric composed mainly of polyurethane fibers, basis weight 50 to 250 g / m ^2, as the thickness of 0.2 to 0.8 mm, or polyester fibers as a main component, basis weight 40~150g / m ^2,
It is advantageous to use one having a thickness of 0.3 to 1.2 mm.

It is preferable that the skin contact member is fixed to the pouch main body such that the direction of expansion and contraction of the nonwoven fabric is in the longitudinal direction of the pouch main body.

[Action]

In the body waste treatment device of the present invention, the pouch body is made of PVC, so that it has a good feel to the skin, and does not hinder skin breathing or sweating due to the good air permeability of the nonwoven fabric of the skin contact member, and at least one direction. The elasticity of the low modulus makes it possible to adhere to the skin without wrinkling, and the texture is soft, there is no discomfort when bending the body and there is no physical irritation due to the edges, especially polyurethane or polyester fiber When a non-woven fabric as a main component is used, the PVC pouch can be securely bonded to the pouch made of waste without leakage.

〔Example〕

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

In the figure, reference numeral 1 denotes a disk-shaped skin contact member, which is formed of a polyurethane non-woven fabric (for example, product name "Espancione" manufactured by Kanebo Co., Ltd.), has a basis weight of 100 g / m ² , and has a ventilation rate of 25 cc / cm ² /
Second, elongation in the horizontal direction 300%, elongation in the vertical direction 400%, modulus of 100% elongation 168 g / cm in the horizontal direction and 212 g / cm in the vertical direction when stretched. And an opening 3 at the center.

Reference numeral 4 denotes a bag-shaped pouch body made of polyvinyl chloride, which has an opening 5 serving as a discharge passage, and a peripheral portion 6 of the opening 5 is high-frequency welded to the opposite side of the skin member 1 from the skin side. It is fixed at. The pouch body 4 is fixed to the skin member 1 in such a direction that its longitudinal direction, that is, the up-down direction coincides with the direction in which the skin member 1 expands greatly.

In another embodiment, the skin member 1 is made of a polyester non-woven fabric (for example, trade name "Sontara" manufactured by DuPont), and has a basis weight of 70 g / m ² , a ventilation rate of 15 cc / cm ² / sec, and a lateral elongation of 180. %, A longitudinal elongation of 110%, and a modulus of 730 g / cm in a transverse direction at a 50% elongation.

The welding between the skin member and the pouch body is advantageously performed with a small opposing area as much as possible so as not to lose the inherent flexibility of the nonwoven fabric of the skin member. Usually, the welding is performed around the periphery of the opening of the skin member. Preferably, it is welded to the pouch body.

The pouch body is not limited to a closed type with the periphery sealed as shown in the figure, but may have a discharge port at the lower end,
Various conventional structures can be used.

In general, in high-frequency welding processing, thermoplastic plastics that can be processed are polyvinyl chloride, polyvinylidene chloride, nylon, and the like having large dielectric loss, and the same kind of welding can be performed. On the other hand, welding of polyethylene, polypropylene, polyester or the like having a small dielectric loss is generally impossible. Conventionally, in high frequency welding, PV
Welding with a C film was not possible unless it was a PVC film, but in the present invention, welding with a PVC film is made possible by forming the skin material into a nonwoven fabric. However, all nonwoven fabrics cannot be welded, and cannot be welded to, for example, an olefin-based nonwoven fabric.

In the body discharge treatment device, the welding strength between the pouch body and the skin member is 1 kg / 2.5 cm width or more, and the PVC film of the pouch body and the skin member are completely integrated or fused together without any gap at the welding point Otherwise, capillarity may cause the discharge to leak through the skin. In this regard, in the present invention, in the case of the polyurethane nonwoven fabric, the polyurethane nonwoven fabric has a large dielectric loss and is easily melted by internal heat due to the use of the nonwoven fabric. It became possible,
In the case of a polyester non-woven fabric, the dielectric loss of the polyester non-woven fabric is small, but the melted PVC resin is filled without gaps between the partially melted polyester non-woven fabrics so that both can be welded. In the case of an olefin-based nonwoven fabric, since the dielectric loss is smaller than that of polyester, heat generation hardly occurs in the olefin-based nonwoven fabric itself, and the olefin-based nonwoven fabric does not adhere to the molten PVC resin.

If the basis weight of the polyurethane non-woven fabric and the polyester non-woven fabric is less than the above values, the air permeability is improved, but the welding between the skin member and the pouch main body becomes incomplete, and there is a possibility that the discharge will leak through the skin member. In addition, the thickness of the skin contact member is too thin, the waist is too thin and it is difficult to stick, and if the above value is exceeded, the air permeability is reduced and the thickness is also increased, giving an unfavorable effect on the skin and having an unfavorable effect. Is advantageous.

If the modulus value of the nonwoven fabric is below the above value, it will be difficult to stick, and it will be easily stretched and it will be stuck in a stretched state, so the skin will always be tensioned. The above-mentioned range is preferable because stress is applied to the skin and causes rash.

〔The invention's effect〕

According to the present invention, a good feeling of use is obtained by using polyvinyl chloride for the pouch body, and skin breathing is inhibited or sweating is prevented by using a highly breathable nonwoven fabric for the skin contact member. Without hindrance, the skin maintains a normal physiological state even when worn on the body for a long time, so that the skin-contacting member does not peel off and does not leak. In addition, the non-woven fabric stretches in at least one direction and has a low modulus property, so the skin is well adapted to the skin, does not cause discomfort, does not give stress to the skin, and has complex irregularities It is also easy to stick on the human body surface. Further, the pouch main body and the skin contact member can be connected to each other so as to have the strength and liquid tightness required for the device for treating body waste, and there is no danger of leakage during use. The manufacturing process is very simple because the skin member can be directly bonded by high frequency welding.
