Abstract:
A toilet device, in particular for bedridden persons, includes a lower shell ( 20 ) whose top side has a support surface ( 45; 80, 82 ) surrounding an opening ( 30 ) to receive the stool and urine of a person on the lower shell, in such a way that there is a first sealing line portion between the person and lower shell, which first sealing line portion extends from the inside of one buttock over the coccyx or lower back region to the inside of the other buttock. An upper shell ( 22 ) can be mounted to the lower shell and is so formed that in a transitional region between the lower shell and the upper shell ( 22 ) connected thereto there are second and third sealing line portions, adjoining the first sealing line portion, in the region of the uppermost insides of the thighs or the lowermost trunk region, which are adjoined by a fourth sealing line portion which extends from one side of the lowermost trunk region over the pubic region or lower abdomen region to the other side of the lowermost trunk region.

Description:
BACKGROUND OF THE INVENTION 
     The invention concerns a toilet device, in particular for bedridden persons, as set forth in the classifying portion of claim  1 . 
     Urination and bowel movements represent major problems not just for bedridden persons but also for the carer staff for reasons of the intimacy of the relationship, hygiene and the work involved. There has therefore been no lack of attempts to provide devices which simplify urination and bowel movements on the part of bedridden persons and resolve the above-indicated problems. 
     A toilet device of the general kind set forth is known from DE 296 12 166 U1. A toilet device as described in that publication has a lower shell which is adapted to the human anatomy with openings for the waist and the thighs and on its underside has a recess of a volume sufficient to accommodate the excretions. The lower shell is completely open upwardly and extends around a person lying thereon in a line which extends from the waist at both sides of the buttocks under the lower legs and between the lower legs upwardly where the lower shell has a projection projecting upwardly between the thighs. There is no contact with the person in the upper region of the projection. For the purposes of hermetically sealing off the interior of the lower shell, the arrangement has an upper shell which is fitted onto the lower shell in such a way that the thighs of the person and the trunk in the region of the waist extend through the corresponding three, out of the container formed by the upper shell and the lower shell. Provided on the projection on the lower shell are connections for a washing water conduit, a warm air conduit and a feces suction removal conduit so that the anal and genital region of the person can be cleaned and dried, the content of the lower shell can be sucked away and the lower shell can be cleaned. 
     A particularity of the described toilet device is that satisfactory sealing of the interior thereof, which receives the feces, is only possible with difficulty in relation to different people, as the periphery of the body in the region of the waist and the periphery of the thighs is very different from one person to another. That results in unpleasant odors in the ambient atmosphere. In addition the toilet device is uncomfortable as the person is supported only in the region of the hips and at the thighs. 
     The Patent Abstracts of Japan in respect of Japanese patent application No 7104551 (publication No 08257073A) discloses a device in which a kind of diaper is fitted to a lying person, the diaper being provided with a connection for sucking away the excretions and a connection for feeding cleaning water and warm air. The operation of fitting the diaper represents a complicated and expensive procedure. 
     EP 0 494 488 A1 discloses a toilet having a pan or tub, on the edge of which can be arranged a replaceable seat component on which a person sits or lies, depending on the shape of the tub. Excrements can be sucked away from the tub. The tub is further provided with nozzles for washing water and for the feed of drying warm air. 
     EP 0 689 790 A1 discloses a portable seat toilet which is provided with replaceable seat covers and a bag for receiving the excrement. 
     The object of the invention is to provide a toilet device, in particular for bedridden persons, which particularly satisfies the demands which occur in a practical context. 
     SUMMARY OF THE INVENTION 
     That object is attained by a toilet device in accordance with the main claim. 
     In accordance with the invention the lower shell is so designed that it comfortably supports in sealing relationship a person thereon, who can be lying or sitting. In that respect the sealing effect or the contact of the lower shell against the person takes place along the insides of the buttocks so that the sealing effect extends directly to the crotch region of the trunk at the insides or between the thighs from where it is closed by means of the upper shell directly over the pubic region. The body regions which are intended to come into contact between a person and the lower and upper shell respectively are of similar dimensions in regard to corpulent and slender persons, irrespective of their sex, so that this device affords comfortable support and satisfactorily sealing contact. The lower shell and in particular the upper shell can be comparatively small. The entire range of demand can be covered with two or three sizes (children, adolescents, adults). 
     The features of claim  2  provide for good adaptability of the toilet device to individual persons. 
     Claim  3  characterizes an advantage embodiment of the lower shell with which satisfactory positioning of a person can be checked in a simple manner. 
     The features of claim  4  provide for a certain spreading of the buttocks, whereby cleaning after a bowel movement is made easier. 
     Claims  5  and  6  characterize advantageous embodiments of the toilet device for cleaning and drying of the person using it, wherein the air evacuation conduit affords the advantage that air is continuously sucked somewhat out of the toilet device. That ensures that no odors occur in the ambient atmosphere. 
     The features of claim  7  afford the advantage that the feces together with the washing water can be disposed of in an extremely simple fashion, in which respect the foil can additionally be such that it covers all regions with which the person comes into contact, so that practically no cleaning of the toilet device is required between two uses thereof. 
     Claim  8  characterizes a configuration of the foil which is particularly handling-friendly. 
     The features of claim  9  afford a simple possible way of ambient air being sucked into the space between the lower shell and the upper shell, even when the space is completely sealingly closed off the person. In addition, with a suitable design configuration in respect of the air feed valve, the reduced pressure in the interior between the lower shell and the upper shell can be adjusted in order for example to ensure that the foil or the receiving bag does not collapse in or that an excessively reduced pressure which is unpleasant to the person does not occur due to the air suction removal effect. 
     In accordance with claim  10  there is provided a supply unit in which all devices for the toilet device are assembled.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring to FIG. 1, a person  4  is lying in a bed which is generally identified by reference  2  and which is for example movable. Inserted between the person  4  and the mattress or sheet of the bed is a portable toilet  6  which extends from the back to the thighs and which projects upwardly between the thighs and covers over the genital region of the person. Hoses or conduits  8  lead from the toilet  6  to a movable supply unit  10  which has operating elements  12  and displays  14 . A remote operating unit  16  which can be gripped by the person  4  is connected by way of a cable  18  to the supply unit  10  or communicates cordlessly with the supply unit in per se known manner. 
     FIG. 2 shows a plan view of the toilet  6  with a person  4  thereon as shown in FIG.  1 . FIG. 3 shows a longitudinal section through the arrangement of FIG. 2, in section in the plane III—III. 
     FIGS. 4 and 5 show cross-sections through the arrangement in FIG. 2, in section in the planes IV—IV and V—V. 
     FIGS. 2 through 5 are described jointly hereinafter. 
     The toilet includes a lower shell  20  and an upper shell  22 . The lower shell  20  has a large-area support  23  for at least the lower region of the back  24  and the lower region of the body including at least the inner upper end regions of the thighs  26 . In the region of the buttocks  28  the lower shell which is almost entirely closed has an opening  30  through which the interior  32  of the lower shell is accessible. The top side of the lower shell  20  is provided with cushionings  34  which adapt to the anatomy of the body and which are extended upwardly in the region between the thighs so that, when a person is lying on the lower shell, there is a peripherally extending sealing line  35  (shown in broken line in FIG. 2) or a peripherally extending sealing region which extends around the opening  30 . Advantageously the support surface of the lower shell around the opening  30  is raised in such a way that the sealing line  35  extends along the insides of the buttocks to the insides of the thighs or the crotch region of the trunk between the thighs, as shown by the dash-dotted lines and as will be described in greater detail hereinafter with reference to FIGS. 11 through 14. 
     Fixed on the lower shell  20  is an upper shell  22  which is open towards the lower shell for example by virtue of it being fixed with a lower portion  36  (FIG. 3) to the end of the upper shell by clipping attachment thereto. The upper shell  22  extends between the thighs  26  and, leaving a hollow space towards the body of the person, is of such a configuration that its cushioned edge region forms a sealing line  38  or a sealing region which adjoins the sealing line  35  formed by the lower shell and extends along the upper end regions of the insides of the thighs from the crotch region, surrounding the genital region, over the lower abdomen region or pubic region. 
     Inserted into the lower shell  20  through the opening  30  is a sheet or foil  44  which forms a receiving bag  42  within the lower shell and which with a flat region  45  covers over the top side of the lower shell  20  in the entire support region for the person  4  and has a projection  46  which prolongs the flat region  45  and which covers over the entire inside of the upper shell  22 . By virtue of the described arrangement, the foil  44 , over the sealing regions  35  and  38  and the coverage thereof of the separation between the upper shell  22  and the lower shell  20 , forms an internal space which is outwardly substantially sealingly closed off and which is delimited only by the inside of the foil and regions of the surface of the person  4 . It will be appreciated that the foil can also be of a multi-part nature, for example the projection can be a specific piece of foil. 
     FIG. 6 shows the foil  44  lying on the lower shell  20 , with the opening  30 , the flat region  45  and the projection  46  for bearing against the inside of the upper shell  22 . The optional incisions in the lateral region of the projection  46  serve for better adaptability thereof to curvatures between the lower shell and the upper shell and in the region of the upper shell. 
     As can be seen in particular from FIG. 3 washing nozzles  50  project into the interior of the upper shell  22  which is advantageously fixed to the portion  36  thereof by way of a hinge  48 . The washing nozzles  50  are connected to a fluid conduit  52 . The opening  53  of a warm air conduit  54  also projects into the interior which is delimited by the foil  44 . 
     In addition, the device has a reduced pressure conduit  56  which is connected to an air evacuation opening  58  of the foil  44 . In addition the foil is provided with an air feed valve  60  which for example is in the form of a simple non-return valve flap, wherein the foil can be reinforced in the region of the non-return valve flap to produce an elastic closing force. 
     FIG. 7 shows an embodiment by way of example of a washing nozzle  50  and the connection thereof to the conduit  52 . In this case the foil  44  is formed in one piece with the washing nozzle  50  insofar as in the manufacture thereof it is directly suitably shaped and apertured or a nozzle attachment is welded to the foil. The conduit  52  extends through the upper shell  22  and protrudes slightly so that the inner edge of the nozzle  50  can be fixed to the projection of the conduit  52 . 
     FIG. 8 shows a modified embodiment in which the washing nozzle  50  is in the form of a separate component which, when the foil  44  is disposed in the upper shell  22 , can be pushed therethrough, piercing the foil, and can be fixed in the conduit  52 . The openings  53  and  58  can be formed similarly to the nozzle  50  and can serve for fixing the foil  44 . It will be appreciated that the nozzles, opening inserts and so forth can advantageously be designed in the form of disposable articles. 
     The conduits  52 ,  54  and  56  and possibly further conduits and cables are combined together to constitute a conduit run  8  (FIG. 1) and connected to the supply unit  10  which includes one or more temperature-controllable cleaning and washing fluid tanks, a hot air blower and a reduced-pressure pump for connection to the reduced-pressure conduit  56 . Also provided in the supply unit is a filter device for filtering air which is sucked out of the toilet  6  so that no odorous effects occur in a room. 
     FIGS. 9 and 10 are perpendicular and horizontal sections showing a closing device  62  for the receiving bag  42  which is passed through the opening  30 . 
     The closing device  62  includes two arms  66  and  68  which are mounted scissor-like at a pin  64  and which are accommodated in an annular recess  70  in the lower shell  20  and which extend around the opening  30 . The arms  66  and  68  are elastically biased in the opening direction by means of a spring  72 , with the opening movement being limited by an abutment  74  provided on one of the arms. By means of a Bowden cable  76  actuated by an electric motor  78 , the arms  66  and  68  are pivotable in such a way that they close the opening, entraining the foil  44  which is passed through the opening  30 . Provided at the inward sides of the arms  66  and  68  is a heating wire  71 , wherein the foil or the receiving bag  42  is closable when the heating wire is supplied with power. 
     The mode of operation of the described device is as follows: 
     A lower shell is provided with the foil  44  by the receiving bag  42  being introduced through the opening  30  and the remaining foil, leaving the opening  30 , being laid onto the top side of the upper shell  22 , in which case fixing devices in the form of adhesive points, hook-and-loop fastener strips and the like can possibly be provided. The portion  36  pivotably connected to the upper shell  22  is fitted to the end of the lower shell. Washing nozzles  50  and openings  53  and  58 , provided in the projection  46  of the foil  44 , are fixed to the associated conduits and the air feed valve  60  is fixed to the corresponding aperture in the upper shell. The projection  46  is thus fixed to the upper shell, in which case additional adhesive points, hook-and-loop fastener strips and the like can be provided. 
     The lower shell is pushed under the person  4  until the thighs of the person come into firm contact against the corresponding cushion or edge regions of the lower shell or the buttocks region of the person is above the opening  30 . The upper shell  22  is then pivoted upwardly so that the edge regions thereof come to bear against the top side of the lower shell  22 , the inner thigh regions and the lower abdomen region and enclose the genitalia. The pivot  48  can be provided with a latching device which holds the upper shell  20  fast so that the lower shell rests securely on the person and the internal space defined by the foil  44  and the person  4  is sealed off as well as possible relative to the exterior. 
     The person  4  by way of the remote operating unit  16 , sets the reduced-pressure pump contained in the supply unit  10  in operation so that the internal space defined by the foil is put under a slightly reduced pressure, in which case fresh air is sucked in through the air feed valve  60 , the air being filtered or neutralized in respect of odor or slightly perfumed in the supply unit  10  so that no unpleasant odors can occur. 
     The person  4  can now perform a bowel movement and urinate. The person then uses the remote operating unit to implement a cleaning procedure in which cleaning fluid is supplied by way of the suitably arranged washing nozzles  50 , to reliably clean the genital and buttocks region of the person. A rinsing operation can then follow, in which rinsing is effected with clear water which possibly contains skin-care additives. The drying step is then initiated by the warm air blower of the supply unit  10  being activated. In that case the reduced-pressure pump in the supply unit advantageously switches to a higher delivery. The temperature controls and flow speed of the fluids and the air can be individually adjusted or pre-programmed. The warm air blower is switched off after the drying operation. The reduced pressure which is then greater reduces the receiving bag to a slightly larger volume than the excrement and liquid contained therein. In that condition, the electric motor is actuated to close the receiving bag  42  and then the heating wire  71  is supplied with power to weld the foil  44 . It will be appreciated that the reduced pressure when actuating the closing device can be intensified by increasing the power supplied to the reduced-pressure pump. After the receiving bag  42  is closed the reduced-pressure pump is switched off and the upper shell pivoted open. The upper shell is then pulled away together with the lower shell from under the person. The projection  46  of the foil can then be released from the upper shell, in which case all nozzles, opening inserts and so forth remain on the foil and the entire foil is removed with the closed receiving bag for disposal thereof. In that case, all handling can be effected from the outside of the foil. It will be appreciated that the foil advantageously comprises biodegradable material so that total disposal thereof without any problem is possible. 
     The described device can be modified in many different ways. The nozzles and openings can be arranged at different locations from those shown and can be provided at least in part also in the lower shell. In addition the shells can be arranged in such a way that a person does not necessarily have to be lying, but can also use the toilet device in a sitting position. The foil  44  can be enclosed in the region of the opening  30  by a pull-tight band which forms the closing device. Stowage space for a plurality of used foils  44  or receiving bags can be provided in the supply unit. The cushioning can be at least in part inflatable by way of a suitable compressed air connection in order to provide for optimum adaptation to the person. The air feed valve  60  can be in the form of an electrically operable valve. The upper shell can be mounted to the lower shell only when a person is on the lower shell, and so forth. 
     The described embodiment of the toilet device represents a maximum expansion stage in which parts of the re-used structural groups of the toilet device, which come into contact with the person, are covered with the foil which is used once and which is such that it receives all excrement and liquids and is disposed of after use of the toilet. From the point of view of the carer staff this signifies a major simplification in their work. 
     In a modified embodiment the toilet device can be used without the foil  44 . The upper shell and the lower shell then admittedly have to be cleaned between two uses; that device however still retains the great advantage of the high level of comfort and convenience for the user and the good sealing action which protects the ambient atmosphere from unwanted odors. 
     It will be appreciated that, in the case in which no foil is used, it is possible to connect to the lower shell a feces suction removal conduit (not shown), by way of which the content of the lower shell can be sucked into a suitable tank in the supply unit. 
     A further embodiment of the toilet device which in the illustrated example is employed without a foil will be described hereinafter with reference to FIGS. 11 through 16. 
     The lower shell of this embodiment is shortened in comparison with the embodiment shown in FIG. 3 and, in its front region, has a support surface  80  for the coccyx region of a person. Laterally of the opening  30  the support surface  80  is extended in support regions  82  which are formed by inclined side surfaces of a projection  84  which is generally U-shaped in plan and which is open towards the support surface  80  and which in other respects extends around the opening  30 . The front ends of the support regions  82  are specifically designed with inclined surfaces  86 , the function of which will be further described hereinafter. At the rear side the projection  84  has a recess  88 . To close its internal space the lower shell  20  preferably has a slider  90  which is shown in dash-dotted line in FIG.  14 . 
     The upper shell  22  is generally U-shaped in cross-section and is in the form of an arcuate portion involving an angle of about 90°. The U is open at the lower end  92  of the upper shell and closed at the upper end  94 . The lower end  92  and the projection  84  are matched to each other in such a way that the upper shell  22  can be inserted in the projection  84  of the lower shell  20 , bearing against the wall regions thereof, in which case the front edges  96  of the projection  84  go flush into the edge  98  of the upper shell  22 . The back of the upper shell  94  has a conduit attachment  100  which has a multiple connection  102 . 
     FIG. 15 shows a diagrammatic view illustrating a possible way in which the upper shell  22  can be slidably and tiltably fixed to the lower shell  20 . For that purpose, in the region which can be inserted into the projection  84  of the lower shell, the upper shell is provided with two diametrally oppositely disposed mounting trunnions or journals  104  on which are mounted fixing portions  106  which are displaceable relative to fixing protrusions  108  provided on the projection  84 . The surfaces which are in mutual contact of the fixing portions and the fixing protrusions are serrated so that displacement involves a latching action. By means of the depicted fixing arrangement, the upper shell  22  is slidable relative to the lower shell  20  and tiltable to a certain extent. 
     FIG. 16 shows a plan view of the multiple connection  102 . The multiple connection includes two warm water feed conduits  110 ,  112 , a warm air feed conduit  114  and an air evacuation conduit  116 . By means of a bayonet  118 , it is possible to connect to the multiple connection  102  a corresponding counterpart portion of a multiple connection hose leading to the supply unit  10  (FIG.  1 ). 
     The warm water feed conduit  110  leads for example to washing nozzles which are disposed in the region  120  of the upper shell  22  in order to direct washing water onto the anal region of a person using the toilet. The warm water feed conduit  112  is connected to nozzles which are arranged in the region  122  of the upper shell  22  for cleaning the genital region of a person. The warm air feed conduit  114  is connected to a plurality of outlets (not shown) through which warm air is introduced into the upper shell in order to flow along the genitalia and the anus of the person. The air evacuation conduit  112  leads directly into the internal space of the upper shell  22 . 
     The mode of operation of the described toilet device is as follows: 
     The lower shell  20  is passed to a person who is for example in a bed. The person who is lying on the back pushes the lower shell between the legs and under the buttocks, in which case the lower shell is pressed into the soft bed mattress and the coccyx comes to lie on the support surface  80 . When the lower shell is further pushed into position, the inclined surfaces  86  bear against the inside of the buttocks and slightly spread them so that the anus is exposed. Satisfactory positioning in this fashion can be assessed by an operator for example through the recess  88 . The upper shell  22  is now fitted into the lower shell  20  and urged downwardly so that the edge  98  comes to bear against the pubic region, enclosing the genitalia. Overall there is between the person and the lower shell a seal which extends from the coccyx region along the insides of the buttocks. A further sealing region is afforded by the edge  98  of the upper shell which is accommodated slidably and tiltably in the lower shell and which is pressed against the pubic region; the further sealing region extends over the pubic region on both sides thereof in a direction towards the sealing region formed by the lower shell. The transitional region between the two sealing regions, which extends directly from the inside of the buttocks along the uppermost inside of the thighs or the lowermost trunk region (crotch region) is formed by the lower shell and/or the upper shell, depending on the respective height of the projection  84 . 
     From the point of view of the person, this provides a comfortable lying or sitting position in which the internal space of the upper and lower shells is soundly sealed off by the person. The multiple connection  102  is now connected to a corresponding multiple connection of a connecting hose between the supply unit and the toilet can be used, as described hereinbefore. During use, an air suction removal effect takes place continuously, which can be promoted by an air feed valve (not shown), through which external air flows into the internal space in the toilet device. That ensures that the ambient atmosphere is not exposed to any odor effects. After use of the toilet is concluded and the person has been cleaned the slider  90  is closed so that no odor effects occur when the lower shell is pulled out from under the person. 
     For the purposes of emptying and cleaning the lower shell  20  it can be advantageous for the lower shell itself to be of a two-part structure, as is indicated by the broken line  124  in FIG.  13 . 
     The toilet device, as shown in FIGS. 11 through 16, can also be modified in many different ways. For example it can be used together with a foil, similarly to the embodiment first described above. The lower shell can be provided with a feces suction removal conduit. In a minimal embodiment, all conduit connections and supply openings can be omitted so that the upper and lower shells are used as a comfortable and luxury toilet which only involves minimal odor effects. The upper and lower shells can be designed as disposable products insofar as they are made from suitably inexpensive, advantageously biodegradable plastic material or other environmentally friendly materials which for example contain a high proportion of natural fibers. In a modified embodiment the upper shell can be so designed that it is not fixed by attachment directly to the projection  44  but has a fixing loop which can be fixed from the outside to the lower shell  20  for example as shown in FIG. 12 in the left-hand region thereof. 
     FIG. 17 shows a longitudinal section through a modified embodiment of a lower shell. The lower shell of this embodiment, generally indicated by reference  20 , is of a double-shell nature with an outer shell  126  and an inner shell  128 . The two shells are formed integrally with each other and form between them a hollow space  129  into which leads a connection  130  which can be connected to a suction removal or reduced-pressure conduit. The walls of the inner shell and the outer shell are provided with holes  132 . 
     The embodiment of the lower shell shown in FIG. 17 affords the advantage that, when the connection  130  is subjected to the action of reduced pressure, air is sucked through the holes  132  into the hollow space  129  and from there sucked away through the connection  130 . If a foil as described with reference to the embodiment described hereinbefore is introduced into the internal space  134 , then the foil is subjected to a suction effect by the holes in the inner shell, so that it bears securely against the inside of the inner shell. The holes in the outer shell  126  serve to apply a suction effect to the foil which covers parts of the outward side of the outer shell so that the foil is securely held there. It will be appreciated that only those regions of the outer shell against which a foil comes to bear have to be provided with holes. It may be advantageous for the foil to be caused to press or bear against the inside of the inner space by injecting air and then, if necessary, subjecting it to a suction attraction force by way of the holes. 
     It will be appreciated that features of the described embodiments can be combined together in very different ways. 
     The specification incorporates by reference the disclosure of German priority document 199 56 722.0 filed Nov. 25, 1999 and International priority document PCT/EP00/09560 filed Sep. 29, 2000. 
     The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
