The invention relates to a device for collecting urine from an incontinent woman by introduction of a piece around the urinary meatus and its capture with a view to evacuation, as well as the collection and retention of stool in a pocket. he is a device for female incontinence, worn permanently. The invention does not have to respond to a problem of contamination and waste disposal.

Patent EP 0 549 988 A1

Absorbent hygienic article for single use. The invention relates to a layer in which is inserted an absorbent pad that can be thrown into toilet. This is a technical response reserved for people carriers of diapers.

In general, wearing diapers, or any other device placed on the body of the subject, a suitable solution in cases incontinence, is not a universal response to the problem of collection and disposal of human waste. Besides the fact that patient may refuse to do so for aesthetic reasons, comfort or dignity, it can be medically contraindicated (wounds, macerations, bedsores).

• pour les patients alités : un bassin de lit classique, en inox ou matière plastique, rigide, glissé par le personnel soignant sous les fesses du sujet ;
• pour les handicapés sur fauteuil (garde-robe) : on insère dans des glissières prévues à cet effet, le réceptacle approprié, en matière plastique rigide (seau, cuvette) ;
• pour les enfants malades:un réceptacle rigide style pot de chambre.

For the largest category of non-autonomous persons, apart from specific devices of the type described above, or the wearing of diapers, each emission of urine or excrement is used:

• for bedridden patients: a classic bedpan made of stainless steel or plastic, rigid, slipped by the nursing staff under the buttocks of the subject;
• for the handicapped on armchair (wardrobe): one inserts in slides provided for this purpose, the appropriate receptacle, made of rigid plastic material (bucket, bowl);
• for sick children: a rigid receptacle style chamber pot.

These conventional receptacles, made of rigid material (basin, bucket, bowl, pot) are presented to the patient without special arrangements. The staff caregiver recovers said receptacles after emission of excrement and urine, transports them to a suitable place, gets rid of their contents in the wastewater circuit, washes, rinses, disinfects and optionally sterilizes said receptacle for reuse.

• Complexité des manipulations:
• Le personnel soignant est astreint à une vigilance particulière pour éviter tout contact avec des matières hautement septiques,notamment à l'occasion de projections accidentelles. De plus, la multiplication des manipulations (transport, vidange, lavage, rinçage, désinfection, stérilisation) mobilise un temps considérable, facteur de dépense de santé ;
• Risque de contamination:

This multi-day practice poses the following problems:

• Complexity of manipulations:
• The nursing staff is particularly vigilant to avoid contact with highly septic materials, especially during accidental projections. In addition, the multiplication of manipulations (transport, emptying, washing, rinsing, disinfection, sterilization) mobilizes a considerable time, factor of health expenditure;
• Risk of contamination:

The urine and feces collected may be contagious (bacteria, viruses, (retrovirus, cytomegalovirus, etc ...). Spread in the receptacle, above of the gluteal plateau and sometimes on the outer walls of the pelvis to which it is necessary to impose various movements to clear it and proceed to manipulations described above, they may be in contact with the ill -autocontamination-, or the nursing staff.

• Risques pour l'environnement :

In addition, the practice of emptying the toilet (often urine in the sink) promotes the proliferation of nosocomial infections. Public health standards are currently used even in sexual relations (condoms) and medical waste, but leave aside the problem of contamination in the collection of excrement and urine.

• Risks for the environment:

Wastewater treatment is not able to respond effectively to infectious problems, known or sometimes new, mentioned above.

In addition, urine and excrements are able to contain degradation of drugs or substances administered to patients (eg radioactive isotopes). In addition, the washing and disinfection of receptacles imply the massive use of detergents and disinfectants, which found in the environment, are likely to distort balances.

• vue supérieure:

une partie antérieure,arrondie, ouverte en haut, munie d'une poignée en avant.

• une partie postérieure angulaire, recouverte d'un plateau fessier.

-vue latérale:(parois et faces latérales)

• par rapport à l'horizontale, angle ouvert en avant, angle fermé en arrière
• la partie antérieure comporte un rebord large, arrondi, la partie postérieure un rebord droit.

It should be remembered that the classic hygienic basin, used in particular in FRANCE, rigid, of oval shape comprises:

• superior view:

an anterior part, rounded, open at the top, provided with a handle in front.

• an angular posterior part, covered with a gluteal plateau.

side view: (walls and side faces)

• relative to horizontal, open angle forward, closed angle back
• the anterior part has a broad rim, rounded, the posterior part a straight rim.

The droppings, emitted in the rounded opening of the anterior part, slide backwards, in the background, under the buttocks.

The following patents are known:

PATENT US 4,827,540 A

This is the combination of a pond cushion and a garbage bag: these two elements are interdependent. The fixing on the basin is done at the level cushion by adhesive tape. Closing is done by means of two flaps attached to the cushion, converging through a clip that pulls a The bottom of the bag is lined with a layer of absorbent cotton.

PATENT US 5,394,571 A

It is a set including an inflatable basin shaped iron to horse and a garbage bag. The bag is lined internally with a material absorbent to resist splashing.

The bag has a drawstring in the form of a plastic tie flattened, flexible on the horizontal plane but relatively rigid on the plane vertical. This link is inserted into a gutter around the circumference internal seat which has the effect of securing the inflatable pool to the bag. waste. After use, the drawstring allows to extract the bag collector out of the inflatable seat, through a front hole however that the inflatable basin stays in place under the buttocks of the patient.

PATENT FR 1 551 239 A

It is a complex device combining two elements: a support in basin shape and an absorbent layer.

The support is constituted by a basin of plastic material whose part front is closed by a hinged lid or "nose", equipped with a system snap or magnet and has an outer bead of foam rubber.

The layer is like an envelope at the bottom of which is fixed a thick disc made of a flexible and sanitized material (eg polyurethane). This layer has a side pocket and a hem peripheral thanks to which it can be mounted on the nose and the edges of the support.One of the sides of the side pocket is optionally doubled with a Absorbent pad: the latter is not in contact with the droppings but with the patient's buttocks and is only intended for his comfort.

Even though the layer would be used on conventional ponds, what claims the inventor, it should be emphasized that, on the one hand the rounded anterior opening of the basin would be upholstered and the excrement accumulate in contact with the patient and that, on the other hand, in the absence of specially designed basin with articulated nose, the coating, simply laid on the receptacle, would not present the necessary adjustment guarantees.

PATENT GB 1 079 441 A

This is a hygienic basin cover that is intended to fit on a special basin.

The adjustment is done at the back thanks to two holes in which come engage the corresponding protrusions of the special pelvis and forward through a cord passing through four holes forming a closed loop.

These four inventions relate to sets and can not be used on conventional hygienic basins to which they are added (US Patent 4,827 540A -coussin-) or substitute (US Patents 50394 571 A -bassin Inflatable-, FR 1 551 239 A articulated nose support GB 1 079 441 A basin with projections-).

We finally know:

PATENT US 4,882,794 A.

This is a round layer, glued to the center of a flexible shape sheet circular.The edge and the top of this sheet are gathered by a rubber band stitched or glued for adjustment on a round receptacle, both at level of its bottom than its top, such as the "bed pan" drawn on the different from the classic French hygienic basin in that it does not has no posterior and buttocks. In these circumstances, the coating thus described protects neither the inside nor the outside of the tray buttocks and does not protect the external side walls of excrement.

In addition, the inventor claims the presence of an absorbent element, preferably a cotton bead and in addition, a layer of absorbent fiber.

PATENT EP 0 429 065

It is a pelvis cover fitting by means of an elastic filament sewn on the unwelded portion and closing with an adhesive.

This cover does not fit on a classic bedpan, lack of power penetrate into the hollow of the gluteal plateau that receives the droppings. The invention does not contain an absorbent or gelling agent.

APPLICATION FOR CERTIFICATE OF ADDITION 73 11475

This is a protective shell for a hygienic basin which, placed at the inside of the basin, must fold 2 cm on the edge. The dimensions indicated in the description (45 cm in its greatest length) make it possible to ensure "cleanliness inside the hygienic basin" and only the rounded anterior part is protected but not the gluteal plateau, the side walls and back. There is no provision for adjusting or closing. The invention does not include an absorbent or gelling agent.

APPLICATION FOR PATENT OF INVENTION FR 2 654 929 A

It is a single-use bag for hygienic bassin comprising the interior a very absorbent material.Adjustment and closure are made using an adhesive tape.

The description makes no mention of any particular form; it is only also stated "the interior is lined with an absorbent material." This invention has a very general character.

Under these conditions, the prior art does not solve the problems posed and the The purpose of the present invention is to provide a coating which adapts to the classical basin as described. Thanks to its shape and dimensions, it covers the entire interior of the receptacle and in particular it fits into the part located under the buttock. It covers the outside of the gluteal plateau edges and edges, the outer walls and the handle of the receptacle. a sliding link ensures fit to resist printed friction against the patient's body for the placement and removal of the pelvis. defect, the coating, adhering to the buttocks of the patient, might leave to shed droppings and lose its raison d'être. After use, stretching sliding link and tie guarantee the tightness of the closure and the asepsis of manipulations.

The presence of gelling agent that traps liquids instantly secures these manipulations. It is a neutralized, polymerized, cross-linked polyacrylate which absorbs the liquid, gels it and retains it even under a certain pressure. While cotton is a filamentous, highly cross-linked substance, keeps the liquid between its mesh but does not imprison it and restores it to the slightest pressure.The conditions of collection and storage of such wastes are therefore optimized by the presence of the gelling agent.

In addition, 7 to 10 g of gelling agent are sufficient in common use by basin, whereas for the same result it is necessary to provide layer of cotton 1 cm x 20 cm x 40 cm.Before as after use, the choice of gelling agent compared to cotton reduces volumes.

The material used must be flexible and impervious (eg polyethylene, polypropylene, nonwoven and polyethylene complex, supersoup paper or wadding with impermeable fabric) It may be the product of an extrusion or be a molding (vinyl type, latex). It can be lined with a non woven to improve the comfort of the subject. The material used must be opaque, either because of its texture or because of any other process (printing, collage, dubbing).

The element (boards 1 to 5) is made from two sheets of form polygonal, (Figure 2) welded together edge to edge, (4,6,9,11) except at summit (Figure 2). It has a pointed, flat or rounded base (7). The form polygonal is generally designed to fit any form of receptacle.

The top of the coating is generally horizontal (2) but can be slightly convex (Figure 10) open, ending in a hem all over length (13, 14) in which one or two sliding links run, in this case of different color (Figure 4 - 14). The prehension of these links takes place at through 2 indentations in opposition to the center of the coating, (13) at each of its ends (14).

Figure 3: Side view of the hem with medial insertion of the links (13)

Figure 4: Side view of the hem with medial insertion of the links (14)

These links allow the adjustment of the coating once laid and inserted into the receptacle-before use; after use, once pulled out of each side and after tie, they ensure the tight closure of the coating for safe transportation to the disposal site.

The element according to the invention contains a gelling agent. This one can be free, under form of powder, crystals or fibers, spread or glued to the bottom, on the inner surface of the lining in the part placed under the gluteal plateau where slide the droppings. It can be contained in a bag itself glued to the bottom, on the inner surface of the coating in this same part.

This bag is in water-soluble material or weakened by a liquid (ex: cellulosic paper or wadding) in such a way that it breaks on contact and allow the gelling agent to spread. The gelling agent can also present itself inserted in a non-woven or glued on adhesive paper or simply glued, placed at the bottom, inside the coating. The presence of this substance has effect of gelling the liquids almost instantaneously and to allow a easy handling.

Other products may also be added to the gelling agent for reasons of comfort (deodorant) or for medical reasons: antiseptics, virucides, antiretrovirals, microbicides, anticytomegalovirus, bactericides, fungicides, biodetergents, reagents.
