Description

MATTRESS WITH TOILET DEVICE

In general, the present invention relates to a device for draining and recovering bodily fluids, in particular one and / or washing water, as well as a device intended for preventing skin alterations, in particular pressure sores.

In these particular aspects, the present invention is intended to be incorporated in a chair, an armchair, a sofa or a ht This invention aims to improve, in particular the comfort of incontinents (children, disabled, elderly), facilitate bed cleaning, avoid the formation of bedsores

It is intended to be used for bedridden or incontinent people, in hospitals, retirement homes as well as at home

The number of elderly dependent people will increase very significantly over the next decades This situation is due to the progress of medical sciences and a better understanding of aging Among these people, a very large number will be incontinent

Treatment of excrement poses a serious problem Providing people with incontinence with easy treatment, at least for urine, would relieve their distress, improve their comfort and facilitate the work of caregivers

Traditionally two methods are commonly used for the treatment of urine

One method uses absorbent pads, diapers, disposable pads or towels that absorb and keep one excreted In hospitals, nursing homes or homes for the dependent elderly, the pads are changed at fixed times, which has the effect of leaving the person with their protections engorged with uπne causing discomfort, pain, decubitus cooling and other alteration of the skin Incontinence at night also poses a more complex problem It forces the caregiver to wake up the person several times during the night to check or change the protections, sleep is thus disturbed

These protections are not waterproof If the change is not made quickly, the urine spills into the bed making it necessary to replace the soiled liteπe elements

The other method consists in a continuous treatment of the excretion of urine using a unary probe which equips the person permanently This last method constitutes, for the person, physical discomfort as well as a source of infection

The toilet at the patient's ht is generally carried out using a bowl and a washcloth. As a result, the possibilities of running under running water prove impossible, no provision of the ht allowing it II this results in discomfort for the patient and relative hygiene. This method of washing often requires the intervention of two nursing staff to move and lift the patient. This type of toilet requires considerable effort on the part of caregivers, which can have repercussions on their health, in particular the risk of low back pain.

To wash the toilet with running water, of the shower type, there are lift trucks with washing tub. These force the caregivers to take the person out of their ht, often using a sick survey, the to put in the chanot in order to lead it in a bathroom The manipulation of the patient, the obstruction of the chanot of shower, its arrangement, its cleaning and its high cost pose problems which prevent to resort easily to this solution II is practically impossible to use it at home because of its size and its expensive cost

For the prevention of bedsores, there are inflatable mattresses or cushions filled with water The mattresses must be placed on the existing mattress and require a compressor system They are expensive and noisy The water cushions must be placed on a protection and recovery tank in case of unexpected piercing of these

These devices are expensive, difficult to clean and disinfect. In addition, they only respond to one function, the treatment of pressure sores.

Mattresses, adaptable in a bed or on an armchair, exist and present a recovery system implementing a housing and a basin for recovery of excrement and dirty water which slides in the housing (Patent FR A 2 087 040 and CH 259 604 )

We can cite in this area a mattress using two air and water circuits, the water part of which is removable, making it possible to ensure both good comfort, recovering the excrement and facilitate hygiene (Patent FR A 2 626 467 )

Another mattress, comprising sets of foam rollers and attached rollers containing thermoregulated water, has a modular central zone forming a bowl intended to receive the excrement and soiled water, collected in an external container (Patent FR A 2 688 695 )

A ht for bedridden people allowing them to be washed without leaving them ht which includes a mattress with a raised edge on the entire periphery, a waterproof cover covering the upper face and the edges of the mattress This cover has openings to evacuate waste water Under the cover can be placed an anti-decubitus cushion with an opening corresponding to that of the mattress (Patent FR N ° 2 690 335)

All these embodiments do not include a drainage cushion for the fluids so that the weight of the patient very often requires plugging the central orifices, so it is necessary to have several drainage outlets, in particular at the bottom of the ht This design requires a tilting system. In addition, the raised edges of the mattress can be a nuisance in the comfort of the patient.

The various embodiments cited resolve only one aspect, either incontinence, or the prevention of bedsores, or the toilet at t An incontinent ht has a rigid bowl coming to be housed in the hollowed-out mattress throughout its thickness. The bottom of the bowl, made of rigid material, is curved in its center and has an evacuation in each corner. , overflows on a part of the mattress thus ensuring a certain protection. Drainage elements constituted by spaced foam blocks, are arranged, leaving intervals between them, on a net tightly stretched over the bowl. Above these said blocks is positioned a perforated, waterproof and ngide foam element (US PATENT -4 620 333 RITTER)

This system is of complex realization II involves many elements, in particular for drainage, difficult to clean and disinfect Furthermore, the bowl is made of ngide resin fiber and does not offer the desirable comfort In addition it has four evacuations on two containers

In another system, it is a canvas fixed on a part of the surface of the mattress which, under the weight of the person lying in the ht, takes a curved shape. Above is fixed a perforated plate A cushion of canvas lined with horsehair, placed on the perforated grid, serves as a drainage element (Patent N ° FR A 559 502 DUBAN)

This realization does not have a bowl, uses an uncomfortable metal grid and a horsehair cushion very difficult to clean

The solution, to resolve incontinence, bed washing, bedsores prevention at the same time, using a comfortable arrangement, simple to use, to clean and disinfect, inexpensive, and simple to carry out, does not seem to be provided by the patents cited above

The arrangement of mattresses for chairs, armchairs, sofas or beds for the evacuation and recovery of bodily fluids, in particular urine and the prevention of skin damage, enables these different criteria to be met.

In fact, according to a first characteristic, in the case of installation in a bed for one person, a mattress in three blocks, preferably in flexible synthetic foam and a protective film. Two blocks are made of solid foam The central block has in its center and in part of its thickness, a recess with an upper opening of indifferent shape, circular, square, rectangular, oval whose walls are vertical over part of its thickness and whose bottom flared from top to bottom, in funnel shape to form a bowl, converges to a central tubular opening made in the remaining thickness of the block

The central part of the mattress, thanks to the recess of the central block, forms a flexible bowl which makes it possible to house the drainage elements in order to thus obtain a flat surface of the upper part of the bed In addition the flared part in the form of funnel facilitates the flow of fluids to a single central orifice

The mattress has a protective, removable, waterproof film made of flexible synthetic material. It covers the top of the entire surface and the four sides of the three blocks protruding from below, to provide perfect protection for the blocks by wrapping them. funnel shape to mold itself exactly to the recess of the central part of the mattress It has at its center a funnel-shaped hole extended by a flexible tube welded to the orifice inféπeur du dit funnel This set is housed in the tubular opening of the central block, exceeds it and can be connected to a collecting container Below and to keep the film in place, two straps are fixed on the latter

In order to avoid any soiling due to urine and / or washing water at the time of cleaning, the flexible tube comprises at its end, preferably the female part of a quick coupling with automatic stop preferably made of stainless metal The part male, fixed on a collecting container or on a conduit allowing an external evacuation, for example towards a siphon of soil or a WC, thus comes to adapt on this female part

The protective film is provided, over the entire perimeter of its upper part, with an inflatable tube preferably of the same material as the film II is welded thereon so as to constitute, once inflated, using '' a flap valve, a tank allowing to carry out the toilet or the shower, in the bed even of the patient, without πsque of overflow This inflatable tube does not interfere in πen the comfort of the patient II can be easily deflated outside use for the toilet

To contribute more effectively to the prevention of pressure sores, this same protective film is provided with pockets inside the space formed by the penile rod and in the two ends, over the entire width and of a dimension equivalent to approximately one third of the length These pockets are made of a film, preferably of the same material as that of the protective film and directly welded to it

In the central part, between the two other pockets, another pocket is produced in the same way as the previous ones. Thus this assembly constitutes a real water mattress.

In the central part of the protective film, the top of the discharge funnel is welded in a sealed manner to the two films forming the said pocket. These pockets are swollen, preferably with water and / or air or with any other materials such as using silicone gels, preferably retractable flap valves

This arrangement can also be made for a double bed. In this case, half of the mattress, in the width direction, is made up of the system described above and the other half is made up of three non-hollowed out foam blocks.

For the use in an armchair or any other seat, only the hollowed out part is necessary It is adapted to the respective dimensions of the seats If in this particular embodiment, the arrangement cannot be used for the toilet, it turns out to be very useful for the treatment of incontinence and the prevention of pressure sores

In another particular form, the mattress is constituted by the protective film in the manner of a waterproof pocket. This pocket, of parallelepipoidal shape, of dimension identical to that of a mattress and, preferably of lesser thickness, is produced, preferably made of inflatable PVC. Filling is carried out, preferably using two ports and a valve. The light, rot-proof and hydrophobic filling materials are preferably polystyrene beads. They have the effect of preventing the patient from ending up directly on the bed base in the case where the film forming part of the mattress, following accident, would be pierced and emptied In addition, this form of filling makes it possible to considerably reduce the weight, especially when using the mixture filling materials and liquids. The filling between the filling materials is done, preferably with fluids. The amount of liquid is minimal and the unpleasant effect of pitching is practically nonexistent. The filling materials act as a stabilizer. In this particular embodiment, the upper part of the discharge funnel is tightly welded to the upper part of the film and the lower part of the funnel to the lower part of said film.

The bowl receiving the drainage elements will be made by the weight of the patient alone, the drainage cushion being placed in the middle of the mattress above the evacuation funnel. The peripheral flange will be added to form the tray for the toilet.

This embodiment saves flexible foam blocks. This solution proposed by the invention is less expensive while increasing comfort and prevention of pressure sores. It may or may not have pockets.

In another embodiment the invention can be adapted to a double bed. The protective film will include, in addition to the peripheral tube, a tube sharing half of the bed. The central drain will be offset on one of the two halves of the bed.

In order to drain bodily fluids and provide comfort and allow the person to move easily, the mattress receives, inside the recess, drainage and evacuation elements produced in modes which, while combining maximum comfort, allow immediate drainage and rapid evacuation of body fluids and / or wash water.

According to a particular embodiment, these drainage and evacuation elements are produced by a cushion constituted by filling balls of round, oval or irregular shape, waterproof, non-alterable, non-oxidizable, made of synthetic material, glass or metal, retained in a waterproof synthetic mesh. Instead of the balls, the filling of the net may consist of synthetic fibers. These drainage and evacuation elements are large enough for the person to be able to move without being outside the device.

According to another particular embodiment, the drainage and evacuation elements are produced by a removable cushion, consisting of a flexible, waterproof envelope, made of plastic materials, preferably PVC or food-grade polyvinyl chloride, containing either synthetic foam, air, water or gel. It follows the shape of the recess. Over the entire surface of the cushion, tubular conduits pass right through it and open at its lower faces in channels open downwards in the form of a half tube and oriented from the outside towards the middle part to facilitate the flow of fluids body wash water.

According to another particular mode, the drainage and evacuation elements are produced by a removable cushion constituted by two flexible sheets, preferably made of PVC or polyvinyl chloride food which are welded or glued on either side of another flexible sheet. , preferably PVC but thicker than the other two These three sheets are welded together over the entire perimeter, so as to form two separate pockets on either side of the middle sheet On the upper and upper surface the pockets are divided, according to a quadnllage, by welds, preferably circular in shape and spaced from each other so as to reserve small compartments communicating with each other on the same side, not between the two sides With the aid of valves produced on one of the compartments of the upper surface and the lower surface, these communicating compartments can be filled with fluid, in particular air. At the intersection of the compartments and on part of the surface, welded shapes are practical, preferably with a cookie cutter. , passages which can be of any shape, in particular simple perforations of diameter less than the welded part

According to a variant and a preferred embodiment of the invention, the drainage and evacuation elements are produced by a removable and inflatable cushion, preferably with water and of a dimension corresponding to the recess of the mattress This cushion is placed on the protective film above the recess in such a way that the surface of the bed is perfectly flat. The weight of the filling water serves to stabilize it in its location. Furthermore, water is an excellent means suitable for prevention of pressure sores The permanent mobility of the water allows a change in the points of support with each movement, even a minimal one, of the patient

This cushion is made up of two sheets, preferably PVC or any other flexible, waterproof, inflatable material that can be welded, preferably by high-frequency welding. These two sheets are welded over the entire perimeter thus constituting a pocket Over the entire surface and according to a grid, welds of different sizes are made. The welds define the edges. At each corner of the squares, the welds have a greater dimension, preferably by a third, than the welds located on the sides of the squares. welds and in the center are passages of slightly smaller dimension, preferably of rounded shape, preferably carried out with a punch. When inflated, the spaces delimited by the welds form small communicating compartments The difference in the dimensions of the welds makes it possible to obtain compartments of different sizes At inflation, between the welds and s ur the small compartments, the material performs folds These with the communicating compartments facilitate the passage and flow of fluids, urine and washing water when the patient is positioned on the cushion On the compartment located in the center of the cushion , is welded, preferably a retractable valve to fill with fluids The cushion being exactly on the recess, the filling valve will be housed in the funnel shape of the film and does not interfere with comfort of the patient

This form of cushion is simple, less expensive, while being more effective for drainage because of the multiplicity of passages, folds and small compartments, it is also of better comfort

These particular embodiments when they are filled with water or gel avoid the points of support and, therefore, constitute a good prevention against the formation of bedsores A very permeable, spaced mesh fabric made of synthetic, vegetable or animal material ensures isolation between the skin and the synthetic elements of the cushion and improves the comfort of the posterior part of the person. It is easily washable and quick drying. Its manufacture is carried out with fibers, preferably of polyester, very fine, knitted according to a particular mode, comprising, of multiple spacings. These spacings and the hydrophobic nature of the fibers are effective in draining fluids, especially urine.

It is placed above the drainage and evacuation elements in such a way that it covers the entire central surface of the mattress and overflows on each side of it. In the direction of the largest dimension, the fabric is provided, at each of its two ends, with hook-and-loop fasteners. It is held in place and sufficiently stretched by straps fixed under the mattress which folds upwards, and provided at the ends of each of them with hook-and-loop fasteners allowing rapid fixing thereof.

According to a variant not illustrated, a liquid detection system intended to prevent urination, can be installed under the mattress.

According to another variant, not illustrated, the protective film, under the pockets, includes sealed and low-temperature heating elements, integrated directly into the film. These elements, insulated to avoid any risk of accident, are very useful for the comfort of the patient when the bags are filled with water. They keep the water temperature at a sufficient level to prevent the patient from cooling down

The heating elements can consist of simple flexible pipes arranged in a coil welded or glued or integrated under the protective film. They can be used to circulate thermoregulated water or heating elements. To use the arrangement as described, simply place the cushion on the recess and cover it with fabric. This covers one third of the bed. Of the two thirds remaining at the top and bottom, cotton sheets or sheets are preferably placed. For the other elements of the bed, we proceed as for any usual bed.

In the preferred form of the invention, the urine passes through the perforated tissue, passes through the multiple passages of the cushion and, thanks to the folds and the compartments of different sizes, flows over the protective film to the funnel following the slope of the recess and are discharged through the flexible tube to a collecting container.

Using a hand shower fitted with a flexible and sufficiently long hose, a regulation connected to the cold and hot water inlets of a bathroom, the patient can be washed and receive a shower and a shampoo in bed. To do this, simply remove the sheets, blankets, mattress covers and comfort fabric. The patient is directly on the cushion and on the protective film. The peripheral flange will be sufficient to prevent water from overflowing beyond the bed. The washing water is discharged, passing through the multiple passages of the cushion, by the flexible tube of the protective film extending the discharge funnel. Thanks to the quick coupling, it is then easy to connect a flexible hose bringing the water to a toilet or a siphon. Once the toilet is finished, all the water having, by gravitation, been evacuated, it suffices to wipe the film and the cushion. The materials used are quick drying, wash and disinfect very easily

The arrangement according to the invention is simple, rustic and easy to set up. It increases the comfort of the incontinent user who no longer needs to use disposable protections and to be awake to carry out the changes This arrangement is very effective in preventing pressure ulcers and skin damage by avoiding prolonged contact with the uπnes and prolonged app points II allows you to wash yourself including shower and shampoo with water.

Simple to make, the layout is inexpensive Easy cleaning and disinfection ilhmmen all unpleasant odors

It is economical because it eliminates the use of disposable protections and the exchange interventions allows to perform a faster toilet and in good hygienic conditions and avoids the fatigue of caregivers

The development also contributes to environmental protection by eliminating the use of disposable protections, which has the consequence of reducing the use of cellulose necessary for making disposable protections and eliminating the waste, hospital type, generated by the use of said disposable protections

The arrangement of the present invention consists in draining the urine and / or washing water and in evacuating it as quickly as possible while presenting a pleasant comfort to the person. The very small amount of uπne remaining in the permeable tissue will be evaporated quickly. by the heat given off by the person's own body The arrangement of the present invention exempts the caregiver from any intervention in the treatment of incontinence and minimizes the discomfort or inconvenience for the person

By the simplicity and the rusticity of its components, the arrangement is extremely easy to clean II can also be disinfected quickly The arrangement allows, by collecting urine, to control the quantity emitted by the person as well as their appearance

These pockets are filled with fluids, preferably water using retractable flap valves (15). This film has a shaped evacuation orifice (10), preferably in a funnel extended by a flexible tube (11).

According to a preferred embodiment of the invention and in accordance with FIGS. 6, 7, 8, the drainage and evacuation elements (16) are produced by a removable and inflatable cushion (16), constituted by two sheets (17), of preferably PVC or any other flexible material that can be welded, preferably by high frequency welding. These sheets (17) are welded over the entire perimeter (21) thus constituting a pocket. Over the entire surface and along a grid, welded shapes (18 and 18a) are produced, preferably rounded, of different sizes so that the welded spaces (18) located at the four corners of the square are one third larger than the spaces welded (18a) which are located on the sides. On part and in the center of these welded shapes (18 and 18a) are made passages (19 and 19a) of slightly smaller dimensions, preferably of rounded shape, made with a punch. The passages (19 and 19a) respect the same proportions as the welded shapes. When these delimited spaces are inflated by the welded shapes (18 and 18a) create small communicating compartments (20). The different dimensions of the welded shapes (18 and 18a) make it possible to obtain inflation, between the communicating compartments (20) and the welded shapes (18 and 18a), folds (23) of the material which facilitate when the patient is located on the cushion (16), the passage of fluids, urine and washing water

On the central communicating compartment (20) is welded a retractable flap valve (22) for filling with water and / or air

This embodiment is simple to execute, has only one valve (22) which will be housed in the funnel shape of the evacuating hole (10) of the protective film (8) The welded shapes (18 and 18a) are easier to make, more resistant and the assembly turns out to be less costly

According to another particular mode, presented in FIG. 9, the drainage and evacuation elements (16 are produced by a removable cushion (16) constituted by two flexible outer sheets (17), preferably made of food-grade PVC or polyvinyl chloride, welded or glued on either side of another flexible median sheet (24), preferably made of PVC but of a thickness greater than the other two These three sheets are welded together over the entire external penetrator (21), so as to constitute two separate pockets on either side of the median sheet (24)

On the lower and upper surface, the pockets are divided, according to a quadπllage, by welded shapes (18), preferably circular and spaced from each other, so as to reserve small communicating compartments (20) between them on the same face in no between the two faces Using filling valves (22) produced on one of the compartments (20) of the upper surface and of the lower surface, these communicating compartments (20) can be filled with fluid in particular of

At the intersection of the compartments (20) and on a part of the surface, welded shapes (18) are practical, preferably with a cookie cutter, passages (19) which may be of any shape, in particular simple perforations of diameter smaller than the welded part

According to a particular form presented in FIG. 10, the cushion (16) consists of a waterproof, rot-proof net (27), made of synthetic material, containing non-spongy, non-oxidizable, non-alterable filling balls (28). glass, plastic, or metal

According to another particular embodiment, presented in FIG. 11, the drainage and evacuation elements (16) produced by a cushion (16), consist of a flexible and waterproof envelope made of plastic materials, preferably PVC or edible polyvinyl chloride containing either synthetic foam, air, water or gel They follow the shape of the recess (3) On the whole surface of the cushion tubular conduits (30) pass through it from side to side and open at its lower faces, preferably in channels (29) open downwards in the form of a half-tube and oriented from the outside towards the middle part to facilitate the flow of body fluids and / or washing

On top of these, covering the entire central surface of the top of the mattress (40) and of the drainage and evacuation elements (16) and falling on two sides, a fabric (25) very permeable in synthetic, animal or plant material , having perforated spaces (26), provided at both ends a system of hook-and-loop fasteners, isolates the posterior part of the person and increases comfort.

According to FIG. 12, the mattress (40) is formed by a protective film (8) forming a pocket into which, through the two orifices (32), are introduced filling materials (7), preferably polystyrene balls (31) or any other light, rot-proof and unalterable material. To obtain better comfort and to have a mattress for the treatment of bedsores, the filling is completed with, preferably water using the valve (33).

The upper part of the funnel of the evacuation orifice (10) is connected by welding (35) to the upper film and the lower part of the funnel (10) to the lower film also by welds (35), of preferably through the high frequency welding process or any other process.
