Description

DETAILED DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION The present invention relates to a human excrement disposal device for babies, infants or adults. The device includes a flange that allows for secure mounting, comfortable wearing and low skin exposure.

BACKGROUND OF THE INVENTION Excrement disposal devices are well-known products designed primarily to be worn by people suffering from incontinence, especially patients who cannot stay out of bed. Such excrement disposal devices are mounted around the anus of the wearer or in the area of the genitourinary tract and are intended to collect feces (feces), urine and other excretions and immediately contain them. Such excrement disposal devices, which are mainly known today, consist of a bag in which an opening and a mounting device, generally an adhesive, are arranged at one end.

[0003] The stool processing apparatus is disclosed in the following specification, for example. US3,577,
989 details a disposable plastic bag for people suffering from incontinence. U.S. Pat. No. 4,784,656 describes a container for collecting stool.
The container is formed from two thermoplastic films that are heat sealed along their side edges. GB 2152387 teaches a stool collector for incontinence sufferers with a collection bag consisting of a pair of thermoplastic sheet material panels joined at their edges. EP 245064 discloses a bag consisting essentially of a front wall and a rear wall made of a synthetic plastic material such as PVC. G
B2215605 includes ostomy (os) including synthetic plastic material panels.
A tonomi) bag is disclosed which comprises a film having a wall subsequently needled.

A urine treatment apparatus is disclosed in the following specification, for example. GB1,092,
No. 274 discloses a urine collector for girls comprising a collection bag with plastic material openings. This collector is fixed to the wearer's body by an adhesive material. GB
No. 2,268,882 discloses a urostomy pouch / bag of plastic material with a circular opening surrounded by a first coupling member. The first coupling member allows the pouch to be affixed to the opposing coupling member, which can be attached to the wearer. US4,8
No. 04,377 discloses a collector for collecting urine samples from infants.
This collector has a rectangular flange for gluing. EP01
No. 40478 discloses a disposable diaper having a waterproof barrier, preferably of polypropylene or polyethylene, formed as a flattened bag having a single opening. US 1,092,274 and US 3,292,62
No. 6 discloses a urine collector for girls. Chinese patent application CN1079381 discloses a urine bag for babies having circular and elliptical openings.

[0005] The problem naturally associated with these devices is to securely attach the device to the human body while allowing the stool or urine to be safely stored in the bag. The method mainly used in this field and also described in most of the documents cited above provides a device with a flange surrounding the opening, applying glue to the flange and applying it to the anus. This is a method of sticking around the genitalia or the genitourinary area. Other considerations regarding flange and adhesive selection are disclosed in the following specification.

US Pat. No. 3,734,096 teaches providing a flange from a compressible flexible material such as a plastic sheet about 0.4 mm thick. According to this, the flexibility contributes to making the flange follow the movement of the sphincter during defecation. It is stated that the thickness of the bonding means is not very important.

[0007] EP 0 753 290 A2 teaches providing a flange from a heat-sealable extensible material such as a film, nonwoven. Hydrocolloid adhesives are disclosed for attachment of the flange to the human body. As is well known in the art, such hydrocolloid layers are generally thick, having a thickness of about 1 mm or more. In one example, a 0.33 mm thick nonwoven material and a 1.02 mm thick hydrocolloid layer are specified.

[0008] WO 99/00089 discloses a number of materials for the flange, stating that the preferred choice is an open cell polyurethane foam. The thickness of the adhesive layer used for mounting is not disclosed.

[0009] Despite the above considerations in selecting the flange and adhesive, the problem of unintentional shedding of the stool treatment device is a well-known problem in the art, as disclosed, for example, in GB 2116849. .

[0010] Small openings are desirable in view of the possibility of unintentional shedding and handling after use. In addition, the small opening prevents stool from contacting the wearer's skin over a large area. This alleviates the problem of cortical irritation caused by the age of the elderly or infants who are the common wearers of such devices. On the other hand, the size of the opening must be large enough to completely collect the stool even if the arrangement is not ideal. This is mentioned, for example, in WO 99/00089.

[0011] There is therefore still a need for a human waste management device that guarantees a reliable adhesive installation, can be easily placed and guarantees low skin exposure.

[0012] In an attempt to overcome the aforementioned problems associated with the prior art, it has been found that an adhesive human waste management device having specifically selected flange characteristics can be provided.

SUMMARY OF THE INVENTION The present invention relates to a human excrement disposal device for babies, infants or adults. The present invention is primarily concerned with flanges (12) which can be worn comfortably and ensure a secure attachment to the human body.
) Is provided. According to the invention, the total thickness of the flange (12) and the adhesive layer (20) together is less than 1.3 mm and the transverse diameter of the opening (21) is less than 80 mm.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a human excrement disposal device. Such a human excrement disposal device
A stool treatment device (10) designed to be attached to the anal region and mainly used for collecting feces (feces), or a urine treatment device attached to the urethra and mainly used for collecting urine. be able to. The human excrement disposal device
It can be a device for collecting both urine and feces, and thus a device attached to both areas. Preferably, the human excrement disposal device described above is designed to be used once and then discarded.

FIG. 1 shows a stool processing apparatus (10).

General Description of the Excrement Disposal Apparatus As can be seen from FIG. 1, the excrement disposal apparatus is generally fitted with an adhesive in the opening (21) and in the area around the anus of the wearer. A bag (11) having a flange (12) surrounding it. Any waste management device known in the art can be provided in accordance with the present invention.

The bag (11) used herein is a flexible container for storing excreted stool or urine. The bag (11) is designed to safely contain collected waste and is generally impermeable to liquids, but allows air to pass. Bag (1
1) is a bag (1) under general wearing conditions such as burst during use and further sitting.
It is designed to have sufficient strength to withstand rupture when pressure is applied to 1).

According to the invention, the bag material can comprise one or more, preferably two or three layers. Generally, the layer facing the interior of the bag (11) that is at least partially in contact with stool or urine is called the inner layer. Generally, the outermost layer of the bag that at least partially contacts the wearer's skin and clothing is referred to as the outer layer.

The layer of bag material can include any material, preferably any material that does not allow the bag to pass liquid. Specifically, these layers can include materials such as nonwovens and films. In a preferred embodiment of the invention, a laminate is formed from the nonwoven layer and the film. This laminate can be formed by means well known to those skilled in the art.

The nonwoven layer may be, for example, a felt fabric, a spunlace fabric, a fluid jet entangled fabric, an air laid fabric, a wet laid fabric, a dry laid fabric, a meltblown fabric, a staple fiber carding fabric, a spunbond fabric, a stitch bond fabric, an aperture. Fabrics, or combinations thereof.

[0021] Preferably, suitable film materials for the layer include thermoplastic materials. This thermoplastic material includes all kinds of hot melt adhesives, polyolefins, especially polyethylene, polypropylene, amorphous polyolefins etc .; fibers or polymer binders including natural fibers such as cellulose, wood pulp, cotton, jute, hemp etc. Materials containing a fusible component containing: Synthetic fibers such as glass fiber, rayon, polyester, polyolefin, acrylic, polyamide, aramid, polymetal tetrafluoroethylene, polyimide; two-component high / low melting polymer, copolymer Binders such as polyesters, polyvinyl chloride, polyvinyl acetate / vinyl chloride copolymers, copolyamides, and materials including blends in which some component materials are not meltable; supplied by EXXON Chemical, Ill. Under the name EXXXAIRE Film, Mitsui Air and vapor permeable materials, including microporous films, such as those supplied by East Pressure under the name ESPOIR NO; and DuPont
Hytrel ™, sold by the company ELF Atochem, France
One can select from among breathable monolithic materials such as Pebax ™ sold by the company.

To avoid the problem of trapping and condensing water vapor released from the wearer's body and thereby avoiding hot, moist and unpleasant conditions after a short period of use, in a preferred embodiment it is included in optional layers Preferably, the film is permeable to gases such as air and vapors such as water vapor.

The outer layer of bag material can include a nonwoven layer. Such a layer of material exposes the textured surface to the wearer's skin, thus significantly reducing occlusion problems and greatly enhancing skin health.

In one preferred embodiment of the present invention, the bag material comprises two layers. It is preferable that the outer layer contains the nonwoven fabric layer and the inner layer contains the film.

In another preferred embodiment of the invention, the bag material comprises three layers, preferably one film layer and two nonwoven layers. In a more preferred embodiment, the film layer is sandwiched between two nonwoven layers. By arranging the layers in this way, a closed fiber structure is obtained, which structure gives a particularly pleasant sensation when in contact with the skin of the wearer. In another preferred embodiment, the inner layer comprises a film and the other two layers comprise a nonwoven.

Any or all of the nonwoven layers included in the bag material can be hydrophobic or hydrophilic. If the bag material does not include a film layer, it is preferred that at least one nonwoven layer is hydrophobic. As a result, the excrement disposal device (1)
The penetration of fluid through the bag (11) of 0) is prevented. If the bag material includes a film or a hydrophobic nonwoven layer, the other nonwoven layers can be hydrophilic.

[0027] To provide the required hydrophobicity, the nonwoven layer is generally treated with a surface active material such as a fluorochemical or other hydrophobic finish. However, the nonwoven layer can be coated with liquid impermeable materials such as hot melt adhesives, silicone coatings,
Alternatively, other hydrophobic compounds, such as rubber, vegetable waxes, mineral waxes, etc., can be used for the same treatment, or they can be physically treated using, for example, nanoparticulate or plasma coating techniques.

The nonwoven layer can also be treated with a reagent that improves the softness of the feel of the bag (11). The reagents include, but are not limited to, vegetable oils, animal oils, synthetic oils, silicone oils, and the like. The presence of these reagents is known to give the nonwoven layer a silky or flannel-like feel without giving the wearer a tactile feel. In addition, surfactant materials, including anionic, non-ionic, cationic and amphoteric surfactants, can be added to further enhance softness and surface smoothness.

Additionally, the nonwoven layer can be impregnated with a lotion to provide the desired therapeutic or protective coating lotion benefits. The lotion coating on the bag (11) can be transferred to the wearer's skin by normal contact and movement of the wearer and / or body heat. Mineral oils in the form of lotions have generally been found to be effective in providing a soothing protective coating to the wearer's skin. The nonwoven layer may be impregnated with the solid oil phase cream formulation, or an array of capsules containing, for example, baby oil that ruptures by pressure, heat or water may be incorporated into the nonwoven layer.

According to the invention, depending on the shape of the bag (11) required, the bag (11) can be provided from a single piece of material or from several separate pieces of material. . These separate pieces of material may be the same or different and are sealed at their respective perimeters. The preferred shape of the bag depends, inter alia, on its intended use. That is, it depends on whether the device is used for bedridden or active patients who suffer from incontinence or require an artificial intestinal tract, or for infants.

The bag described herein comprises a wearer-facing portion (16) comprising a separate piece of material.
And a portion (17) facing the garment. The part facing the wearer (16) and the part facing the garment (17) are sealed at the periphery of the bag (11), thereby forming a bag peripheral edge (18). The wearer-facing portion (16) and the garment-facing portion (17) can each independently include more than one piece of material. Preferably, the garment facing portion (17) comprises only one piece of material, and most preferably the wearer facing portion (16) comprises only one piece of material.

To provide the desired bag shape, the part facing the wearer (16), the part facing the garment (17) and the pieces of material they contain may be adhesive, heat bonded or pressure bonded, etc. Fixed to each other by means well known to those skilled in the art. The edge (18) in which the part facing the wearer (16) and the part facing the garment (17) are sealed is the bag (1).
It can be provided inside the bag (11) rather than outside of 1), so that it can be co-extensive with the inner surface (15) of the bag (11) rather than the outer surface (30) of the bag (11). .

Accordingly, bags of various shapes are included in the scope of the present invention. Specifically preferred shapes are flat circular bags, conical bags, frustoconical bags, pyramidal bags, frustum-shaped bags and flat T-shaped bags.

In one embodiment of the present invention, bag (11) includes an absorbent material. This absorbent material
Any absorbent material capable of absorbing and retaining a liquid can be included. The absorbent material can include various liquid absorbent materials commonly used in disposable diapers and other absorbent products such as powdered wood pulp, commonly referred to as air felt. Examples of other suitable absorbent materials include crepe cellulose paper;
Meltblown polymers including co-formation; cellulosic fibers chemically cured, modified or crosslinked; tissues including tissue wrap and tissue laminate; absorbent foam; absorbent sponge; superabsorbent polymer; absorbent gelling material. Other well-known absorbent materials or combinations of absorbent materials.

The absorbent material can be placed in the bag (11) in any suitable way. The absorbent material can be, for example, placed unfixed inside the bag or fixed to the inner surface (15) of the bag (11). For the purpose of securing the absorbent material to the inner surface (15) of the bag, any known technique for securing the absorbent material to nonwoven and film substrates can be used. The absorbent material can be further arranged to have a desired shape or contour (eg, rectangular, oval, circular, etc.).

The flange (12) is attached to the bag (11) according to any means known to those skilled in the art that provides a permanent or peelable attachment. Preferably, however, the flange is attached to the bag by an adhesive. The bag is generally mounted on the flange toward the outer edge of the flange so as not to obstruct the stool or urine from entering.

The flange can be provided in any size depending on the target wearer group of the device. Similarly, the flange can be provided in any shape. The flange is preferably symmetrical, preferably including a plurality of lobes (13).

The flange includes a portion facing the garment (22) and a portion facing the wearer (23). In the preferred embodiment, these are two large surfaces that are essentially flat. However, in the case of a stool treatment device (10) designed to fit the wearer's perineum and / or coccyx region, and a urine treatment device (10) designed to fit the genital and / or perineal region. In the case of), the flange (12) may further include a front protrusion (28) and / or a rear protrusion (29). It has been found that the presence of a protrusion that fits into the perineum is very beneficial when the feces treatment device is worn by women.

According to the invention, the excrement disposal device (10) further comprises attachment means for fixing the device to the wearer. Such means include a body-compatible pressure-sensitive adhesive provided as an adhesive layer (20) applied to the wearer-facing portion (23) of the flange (12), and may further include a bandage. .

In accordance with the present invention, the device is attached to the wearer's perianal or genitourinary tract using any medically approved water resistant pressure sensitive adhesive, such as a hydrocolloid adhesive, a hydrogel adhesive, and the like. You may. A particularly effective adhesive that provides the desired adhesion to secure the flange to the skin of the sensitive perianal area of the wearer while permitting relatively painless application and removal is a three-dimensional matrix. It is formed from a crosslinked polymer using a forming plasticizer.

The adhesive layer (20) can be applied to the wearer facing portion (23) of the flange (12) by means well known in the art such as slot coating, spiral or bead application or printing. The adhesive (20) generally has a basis weight of 20 g / m ² to 2500 g / m ² , more preferably 100 g / m ² to 1000 g / m ² , depending on the end use envisaged and the desired adhesive thickness. Applied. For example, the amount of adhesive (20) for a waste treatment device (10) used for infants may be less than for a waste treatment device (10) designed for active adults suffering from incontinence. it can.

In order to protect the adhesive layer (20), it is preferable that the adhesive layer (20) is covered with a peeling means (not shown) such as silicone-treated paper. The adhesive (20) can cover the entire wearer-facing portion (23) of the flange (12). More preferably, the flange (12) has at least one, preferably two to six, non-adhesive parts. These parts can be adhesive free or parts containing a passivated or coated adhesive. In one preferred embodiment, as is evident from FIG. 1, in one preferred embodiment, non-adhesive lobes (13) are provided on both sides of the flange (12), which serve to avoid contact with the adhesive and to facilitate the placement and removal of the device. As provided, no adhesive is applied over the wearer facing portion (23) of the flange (12). However, it is preferred that these lobes (13) are also covered by the stripping means. If a peeling means is present, the peeling means is removed before applying the human excrement treatment device (10) to the wearer's skin.

The human waste treatment device (10) of the present invention has been found to be particularly useful and beneficial when used with clothing or diapers, preferably disposable diapers.

For a more detailed and clear description of the device (10), the following paragraphs will first define a few terms used herein.

With particular reference to the flange (12), the “longitudinal” axis of the stool treatment device (10) should be understood as follows. The direction essentially defined by the anal groove at the intended wear position defines the longitudinal direction. The vertical axis is the vertical axis crossing the center of the opening (21). The most preferred indication of the intended wear position is the presence of one or two protrusions (28) and / or (29) designed to fit the perineal and / or coccygeal region of the wearer. A less preferred, but preferred indication of the intended wearing position is the fold of said flange (12) before use intended to be placed parallel to the anal groove when placing the product. The vertical axis is generally also the axis of symmetry. Especially the flange (
Regarding 12), the vertical axis of the urine treatment device should be understood as follows. Urine treatment device (1
The direction essentially defined by the line connecting the tailbone, perineum and genital area of the person wearing 0) in the intended wear position defines the longitudinal direction. The vertical axis is the vertical axis crossing the center of the opening (21). The vertical axis is generally also the axis of symmetry.

The “horizontal” axis is an axis perpendicular to the vertical axis and intersecting the center of the opening (21). The lateral direction defined by the horizontal axis is generally aligned with the wearer's hip.

“Unbent” is used with respect to the flange (12). The flange (12) is generally bent along the longitudinal axis for placement in the area around the wearer's anus. Generally, in an uncurved state, the flange (12) is the flattest.

“Center” is used for the purpose of describing a point or a part of an object and coincides with the center of mass if the density of the object or part is uniform. Therefore, for the opening (21), when the flange (12) is not curved, the opening (21)
The center is determined when it is considered that the area inside the outline of is filled with a material having a uniform thickness and density.

The diameter of the opening (21) is such that when the flange (12) is
) Is the length of a straight line passing through the center of the opening (21) on the inner edge (25) of the opening (21). The diameter of the flexible opening (21) must be measured in the absence of any external forces (excluding normally unavoidable forces such as gravity) that affect the shape of the opening (21). The longitudinal diameter of the opening (21) is measured along the vertical axis. Aperture(
The transverse diameter of 21) is measured along the horizontal axis.

Although the present invention includes urine treatment devices as well as stool treatment devices, the following description will focus on stool treatment devices. However, adapting a urine treatment device to the teachings of the present invention is not difficult for those skilled in the art.

Certain flanges greatly enhance wearing comfort and mounting safety,
On the other hand, it was found that skin exposure was minimized.

The flange (12) according to the present invention can be provided from a number of soft, flexible and compliant materials. Further, it is preferred that the material be resilient (especially to follow the movement of the sphincter), extensible, contractile and breathable. Even more preferred materials are those that can reliably embed the hydrogel adhesive, for example by having a three-dimensional microstructure in the surface region. A suitable material is a plastic film. Such a plastic film can also be provided with a layer of pressure sensitive adhesive to which the hydrogel adhesive is more securely bonded. Another preferred material is a laminate of a plastic film and a nonwoven. Other preferred materials include woven fabrics, open-cell thermoplastic foams, closed-cell thermoplastic foams, composites of open-cell foams and extensible nonwovens, and films. The basis weight of such foams is from 5 to 250 g / m ² , more preferably 5
It is preferably 0 g / m ² . Other thermoplastic foam materials or other suitable plastic sheet materials having the properties described above can also be used. Highly preferred materials are nonwoven materials, such as spunbond or meltblown nonwovens. The basis weight of these materials is preferably from 15 g / m ² to 30 g / m ² .

The thickness of such a material providing the flange (12) may be from 0.01 mm to 1.2
5 mm, more preferably 0.05 mm to 0.5 mm, still more preferably 0.1 m
It is preferably from m to 0.3 mm.

The flange according to the present invention includes an adhesive for attaching to a human body. The adhesive is applied to the wearer facing portion (23) of the flange (12) and the adhesive layer (20).
) Is formed. Preferably, the adhesive layer (20) is a continuous layer. In an alternative embodiment, the adhesive layer (20) is applied as a discontinuous pattern, for example a dot pattern. Preferably, the thickness of the adhesive layer (20) is uniform. When the thickness of the adhesive layer (20) is not uniform, the average thickness of the adhesive layer (20) is referred to as the thickness of the adhesive layer (20) in this specification. Further, the adhesive layer (20) must be thin, having a thickness of 0.01 mm to 1.25 mm, more preferably 0.5 mm to 1.1 mm.
mm, most preferably 0.8 mm to 1.0 mm.

According to the invention, the total thickness of the flange (12) is less than 1.3 mm, preferably less than 0.3 mm.
It is 1 mm to 1.3 mm, more preferably 0.9 mm to 1.25 mm, even more preferably 1.0 mm to 1.2 mm. As used herein, the term total thickness refers to the combined thickness of the flange (12) and the adhesive layer. Where the thickness is not uniform, the term full thickness herein refers to the average total thickness. In a particular embodiment of the stool treatment device (10) of FIG. 2, the total thickness is indicated by c.

The bag (11) is provided with an opening (21) for receiving stool or urine from the human body prior to storage in the bag cavity. The periphery of the opening (21) is surrounded by the flange (12). The opening (21) can be provided in any shape or size, such as circular, oval, heart-shaped, and can be symmetric or asymmetric. The opening preferably has a circular shape that is long in the vertical or horizontal direction.
However, the transverse diameter of the opening (21) must be less than 80 mm. The transverse diameter of the flange (12) according to the invention is preferably between 5 and 60 mm, more preferably between 30 and 55 mm, even more preferably between 40 and 50 mm. FIG.
In a particular embodiment of the stool treatment device (10), the transverse diameter is designated by d.

The combination of the thin overall thickness of the flange (12) and the small transverse diameter of the opening (21)
Ensure that stool is pumped into the human waste management device near the anal orifice. The anal groove tightly surrounds the anal opening in an essentially V-shaped manner toward the buttocks. The only way to collect stool near the anal opening is to place a thin flange near the opening. The reason is that it is necessary to push the hips apart in a way that is inconvenient for the wearer and difficult for the caregiver to place the device to achieve.

This interdependence of the thickness of the flange (12), the transverse diameter of the opening (21) and the collection of excreta near the source is due to the stool treatment device (1
It is also shown by the following experimental data for 0). This data can be best understood from the schematic diagram of the experiment shown in FIG. This figure shows a model (220) of the anal area adjacent to the anal opening (210) taken from a sitting male infant. The typical diameter of stool excreted by the wearer is, for example, about 2 cm for infants
Which is represented by d in the figure.

The attachment of the flange of the stool processing apparatus (10) is performed by the bag (1) of the stool processing apparatus (10).
It can only be performed near the anal orifice (210) so as not to obstruct the stool to be captured during 1). The thickness of the flange contributes to such stool obstruction. Thus, an ideal theoretical flange with a total thickness of 0 mm can be mounted closest to the anal opening (210). This ideal distance is represented in FIG. 4 as x, which corresponds to a transverse diameter of the flange of about 2x. The thin flange (230
) Cannot be mounted as close to the anal opening (210) due to its non-zero thickness. The distance to the anal orifice (210) is y> x, which corresponds to a transverse diameter of the flange of about 2y. Conventional thick flanges (240) can only be installed up to a distance z> y to the anal orifice. This corresponds to a larger flange transverse diameter of about 2z. In general, for infants, the value of x is about 25
mm and y are 28 mm and z is 33 mm.

The full thickness of a conventional flange does not allow it to be located near the anal ostium, thus requiring a larger opening. This results in unnecessary and undesirable skin exposure, ie, exposure of the skin inside the open area. Such skin exposure helps cortical irritation. In addition, smaller skin exposure has been found to reduce the need for frequent replacement of human waste management devices, which provides considerable convenience and economic and environmental benefits. Furthermore, it has been found that less skin cleaning is required after the device has been detached. This greatly improves the convenience of the device for caregivers, such as infant mothers.

In another aspect, the present invention makes mounting more secure by providing a larger flange (12) surface area. The surface area of the flange (12) available for adhesive mounting of the device (10) depends on the area inside the opening (21) and on the flange (12).
Is determined by the inner area of the outer periphery of. With respect to the outer circumference, the flange (12) can only have a limited size which depends on considerations for the intended wearer's anatomy and comfort. That is, only small flanges (12) are suitable for infants. Given the outer circumference of the flange (12), the largest surface area for the adhesive (20) can be used if the area inside the opening (21) is small. The small transverse diameter of the opening (21) contributes to such a small area inside the opening (21).

In another aspect, the small transverse diameter of the opening (21) reduces the risk of leakage after removal of the device and facilitates closing and sealing the opening (21).

Further, pressure is applied to the inner circumference (25) of the flange (12), that is, to the edge of the flange in the defecation process. The area of the edge of the flange (12) subjected to such pressure is determined by the total thickness of the flange (12) as can be seen from FIG. Therefore, the thin flange (12) is less likely to fall off than the thick flange (12).
