Description

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to an excrement disposal device for babies, toddlers or adults, and more particularly to hygiene absorbent products such as diapers, incontinence products and feminine protection products. The device is
Equipped with a convenient release sheet that covers the adhesive part of the flange before use.

Background of the Invention Waste management devices are well known products designed primarily for wear by people suffering from incontinence, especially patients who cannot stay in bed. Such waste management devices are attached around the wearer's anus or in the area of the genitourinary tract and are intended to collect and immediately contain feces, urine and other waste. Such waste treatment devices, which are mainly known today, consist of a bag having at one end an opening and a mounting device, which is generally an adhesive, is arranged.

The stool processing device is disclosed in the following specifications, for example. US 3,577,

No. 6 discloses a urine collector for girls. Chinese patent application CN1079381 discloses an infant urine bag having circular and elliptical openings.

There is known a stool treatment device of a type that is attached with an adhesive provided with a release sheet, mainly for protecting the adhesive before use. Such an apparatus is disclosed in the following specification, for example. Japanese Patent Application Laid-Open No. 8-117261 discloses an adhesive covered with paper. GB 2152387 discloses a release sheet provided by paper coated with a silicone coating. For GB2116849,
A release sheet is disclosed that includes a plurality of individually removable sections. The force required to remove each section may be less than the force required to remove a single release sheet that covers the entire area of adhesive that contacts the body, but this solution does However, it is inconvenient that such multiple pieces need to be discarded. EP07532
90 discloses a release sheet with tabs that facilitate removal of the release sheet. The tab projects outside the body contact adhesive layer and is sized for grasping with the thumb and forefinger.

Similarly, the use of release sheets for urine treatment devices is also known and disclosed in the following specifications. A release patch is disclosed in US 3,292,626. GB 1,092,274 discloses a backing paper covering an adhesive material. US
4,804,377 discloses a semi-rigid carrier member that protects the adhesive surface of the device.

All waste management devices disclosed in the above cited specifications are commonly used for bedridden patients. As such, these devices are generally applied by a nurse or other person who is trained and experienced in the application of such devices. However, a recent patent application (EPO application 97110603.4, "Sha
ped faecal management device) and its co-pending applications disclose stool processing devices optimized for use on infants. In such a use, the excrement disposal device is carried and applied in a wide variety of situations, for example, a mother puts it in a handbag and carries it.

Contact with many other items commonly carried in handbags may cause mechanical damage to the human contact adhesive of the waste management device or dust, dust or other substances It may adhere to. These are highly undesirable as they generally reduce the cohesive strength of the adhesive and therefore can lead to leakage or unintentional dislodgement of the waste management device. Unintentional shedding is well known in the art as described in GB 2,116,849. Of course, reliable adhesive protection is also desirable during shipping, packaging or storage of the device, and while the device is stored in a warehouse, hospital or home.

Specifically, as described above, when the mother uses the device, it is important that the release paper can be easily removed, preferably in one operation. For example, EP075329
The tab disclosed in U.S. Pat. No. 0 is incapable of safely grasping and conveniently removing the release sheet, especially when attached to a strong adhesive. Moreover, it is necessary not only to conveniently grasp and remove the release sheet, but also to securely and conveniently hold the other parts of the device to avoid deformation of the flanges and other parts of the device.

Furthermore, it is desirable that the method of removing the release sheet be intuitive to the user and require minimal explanation or experience. This seems to be most important when the device is applied by the mother, or a person who rarely applies the device, for example a grandmother, but the intuitive treatment results in considerable costs for training staff. It is also important for all waste management devices used in hospital settings.

European Patent Application No. 99100119.9 (“A human waste m
management device with an anatomicall
y shaped flange ") discloses a device having a non-planar flange. The flange of the waste management device of this application can have, for example, a hump to fit the perineum and have a three-dimensional shape, for example.
The device can also be provided in a folded, pre-use configuration, as disclosed in the same application. Conventional release sheets can be more difficult to remove when following a crease in a three-dimensional shape or a pre-use shape.

Patent application PCT / US98 / 13298 (“Applicator for
a faecal management device ") discloses a device provided in combination with an applicator prior to use. Correct placement of the device on such applicators is important for accurate and reliable placement of the device on the wearer. When removing conventional release sheets, the flanges are typically subjected to non-uniform forces from different directions, especially when peeled from different ends. This easily shifts the position of the device with respect to the applicator, which leads to a misalignment on the wearer. As a result of such misalignment,
It may be uncomfortable to wear, possibly leading to leaks or unintended dislodgement.

Thus, a reliable adhesive attachment is ensured and can be easily handled and arranged, ie the release sheet covering the attachment adhesive can be easily and conveniently removed and later discarded. There is still a need for waste management devices.

In an attempt to overcome the aforementioned problems associated with the prior art, it has been found that an adhesive waste management device can be provided with a release sheet folded over itself.

SUMMARY OF THE INVENTION The present invention relates to waste management devices for babies, infants or adults, and hygiene absorbent products such as diapers, incontinence products, feminine protection products and the like. The present invention is primarily concerned with the adhesive (2) provided on the flange (12) for attachment to the wearer's body.
It is to provide an apparatus having a release sheet (36) for 0). Release sheet (
36) at least one adhesive contact portion (41) and at least one adhesive non-contact portion (41) at least partially overlying said adhesive contact portion.
42) is included.

The urine treatment device used in. The waste management device may further be a device for collecting both urine and feces, and thus a device attached to both areas mentioned above. The waste treatment device is preferably designed to be used once and then discarded.

Although the release sheet (36) according to the present invention is particularly useful for the flange (12) of a waste management device, such a release sheet (36) may be used in diapers, incontinence products, women's products. It is also useful for covering adhesive parts of other absorbent products such as defense products, especially adhesive-covered flanges.

Recent patent applications (reference number 7321Q) include, for example, first waist region, second
An absorbent product having a waist region and a crotch region located between a first waist region and a second waist region is disclosed. The absorbent product includes a topsheet surrounded by a flange and including a main opening for receiving stool, a backsheet joined to at least a portion of the topsheet, and disposed between at least a portion of the topsheet and the backsheet. An absorbent core, a spacing member disposed between the topsheet and the backsheet to provide a void therein for directing feces, and disposed around at least a portion of the main opening surrounded by a flange to absorb absorbent material during use. A human body adhesive composition for adhering a topsheet of a product to a wearer is provided.

As used herein, the term “flange” refers to the portion of the absorbent product of the waste management device that is adjacent to the opening and thus defines the shape of the opening, and is distinct and distinct. It does not matter whether it is a piece of material or part of another piece of material such as a topsheet of an absorbent product.

The release sheet (36) of the present invention seems to be very suitable for application to an excrement disposal device described later.

General Description of the Waste Management Device As shown in FIG. 1, which shows the feces management device (10), the waste management device is generally adhesively applied to the opening (21) and the area around the wearer's anus. It comprises a bag (11) having a flange (12) surrounding the opening, which is preferably attached. 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 containing excreted feces or urine. The bag (11) is designed to safely contain the collected excrement and is generally impermeable to liquids but permeable to air. Bag (1
1) is a bag (1) under general wearing conditions such as rupture during use and sitting.
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. The layer facing the inside of the bag (11), which generally comes into at least partial contact with feces or urine, is called the inner layer. The outermost layer of the bag that generally comes into at least partial contact with the skin and clothing of the wearer is called the outer layer.

The layer of bag material can include any material, preferably any that is impermeable to liquids by the bag. Specifically, these layers can include materials such as nonwovens, films and the like. 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.

Nonwoven layers include, for example, felt fabrics, spunlace fabrics, fluid jet entangled fabrics, airlaid fabrics, wetlaid fabrics, drylaid fabrics, meltblown fabrics, staple fiber carding fabrics, spunbond fabrics, stitchbond fabrics, apertures. It can include fabrics, or a combination thereof.

Preferably, the film provided is permeable to gases such as air and vapors such as water vapor.

The outer layer of bag material can include a non-woven layer. Such a layer of material exposes the uneven surface to the wearer's skin and thus significantly reduces the problem of occlusion and greatly enhances the health of the skin.

In a preferred embodiment of the invention the bag material comprises two layers. It is preferable that the outer layer includes a nonwoven fabric layer and the inner layer includes a film.

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

Any or all of the non-woven 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 waste treatment device (1
The penetration of the fluid through the bag (11) of (0) is stopped. If the bag material comprises a film or a hydrophobic nonwoven layer, the other nonwoven layer can be hydrophilic.

The nonwoven layer is generally treated with a surface-active material such as a fluorochemical or other hydrophobic finish to provide the requisite hydrophobicity. However, the non-woven layer is coated with a liquid impermeable material such as hot melt adhesive, silicone coating,
Alternatively, other hydrophobic compounds such as gums, vegetable waxes, mineral waxes and the like can be treated in the same manner or physically treated using, for example, nanoparticles 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). This reagent includes, but is 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 greasy feel. In addition, surface-active materials including anionic, nonionic, cationic and amphoteric surfactants can be added to further enhance softness and surface lubricity.

Further, the nonwoven layer can be impregnated with 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 oil in the form of a lotion is generally accepted to be effective in providing a soothing protective coating to the wearer's skin. The non-woven layer can be impregnated with the solid oil phase cream formulation, or an array of capsules containing, for example, baby oil that rupture upon pressure, heat or water can be incorporated into the non-woven layer.

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