(19) The following describes modes of implementing the invention based on an embodiment.

(20) The drop-type automatic excrement processing device in this embodiment, as shown in FIGS. 1, 2, 3, and 8, comprises:

(21) a diaper cover 1 that covers the buttocks and loins of an objective person such as an aged person;

(22) a feces receiver 2 and a urine catching pad 3 that are fitted on the diaper cover 1;

(23) a feces and urine intake pipe 5 that takes in the feces and urine discharged from the objective person such as an aged person through the feces receiver 2 and sends such matter to a waste tank 4;

(24) a valve unit 6 inserted in the intermediate part of the feces and urine intake pipe 5;

(25) a washing-water tank 7 that keeps warm washing-water for washing the buttocks;

(26) a warm wind generating means 8 that generates warm wind for drying the buttocks after washing; and

(27) a control means 9 for controlling working of each unit.

(28) The diaper cover 1 has a similar configuration to an existing one, particularly as shown in FIGS. 1, 2, and 3(a), except that it has an opening for defecation and urination 1h roughly in its center. The diaper cover 1 has a bottom flap 1a that extends downward from the area roughly the center of the opening for defecation and urination 1h and a prolonged portion that extends upward from the area roughly that center and a pair of wrapping flaps 1b and 1c each of which spreads toward the right side and the left side from that prolonged portion. The end of the bottom flap 1a has a hook-and-loop fastener 1af on its outer surface and a hook-and-loop fastener 1aif on its inner surface. The wrapping flap 1b (the flap on the right side) has a hook-and-loop fastener 1bf on its inner surface and the wrapping flap 1c (the flap on the left side) has a hook-and-loop fastener 1cf on its outer surface; the wrapping flap 1c further has a hook-and-loop fastener 1cif on its inner surface. The hook-and-loop fastener 1bf on the inner surface of the wrapping flap 1b on the right side and the hook-and-loop fastener 1cif on the inner surface of the wrapping flap 1c on the left side are male fasteners. The hook-and-loop fastener 1cf on the outer surface of the wrapping flap 1c on the left side and the hook-and-loop fastener 1af on the outer surface of the bottom flap 1a are female fasteners.

(29) Further, the diaper cover 1 is made of a plastic film that has a required strength and is impermeable to water.

(30) The feces receiver 2, as shown in FIGS. 1, 2, 3(c), and 4, comprises:

(31) a belt-shaped rubber sheet part 2a that is arranged in a jointed state on the inner surface of the diaper cover 1;

(32) a defecation tube 2b made of plastic fitted on one end of the belt-shaped rubber sheet part 2a perpendicularly thereto;

(33) a blower tube 8a that communicates with the upper part of the defection tube 2b; and

(34) a water pipe 7a that is inserted in the upper-intermediate part of the blast tube 8a.

(35) As shown in FIGS. 1 and 3(c), one end of the belt-shaped rubber sheet part 2a forms a round end 2a1 having a diameter larger than the width of other part thereof. The round end 2a1 has a circular opening 2a2 concentrically therein having an inner diameter approximately same as the inner diameter of the defecation tube 2b. On the undersurface of the other end of the belt-shaped rubber sheet part 2, a male hook-and-loop fastener 2af is arranged, wherein the faster is to engage with the hook-and-loop fastener 1aif on the inner surface of the bottom flap 1a of the diaper cover 1. The defecation tube 2b joins with the belt-shaped rubber sheet part 2a at the round end 2a1 of approximate-circular shape. Particularly, as shown in FIGS. 2, 3, and 4, the uppermost end of the opening edge of the defecation tube 2b, which is originally a straight cylindrical member, forms a gradual bell-mouth shape. On an opening edge 2b1 of this gradual bell-mouth shaped part, the opening edge of the round end 2a1 of the belt-shaped rubber sheet part 2a is put, and then, they are fixedly joined aligning the axes of the circular opening 2a2 of the round end 2a1 and the defection tube 2b. In this embodiment, this joining is performed using glue.

(36) The blower tube 8a is, as shown in FIGS. 2, 3(c), and 4, a hose component the upper end of which is connected to the upper-intermediate part of the defecation tube 2b. The bottom end of the blower tube 8a is connected to the warm wind generating means 8 as shown in FIG. 8. As shown in that figure, the blower tube 8a has a pair of male-female detachable connectors 8a1 and 8a2 in its intermediate part. Thereby, the blower tube 8a can be detached from the warm wind generating means 8 depending on the necessity. Particularly, as shown in FIGS. 2 and 4, the jointing between the blower tube 8a and the defecation tube 2b is formed in a configuration as follows: The blower tube 8a is jointed to the defecation tube 2b in an upward-slant direction so that the upper end thereof opens toward the upper end of the defecation tube 2b.

(37) The water pipe 7a is a hose component having a diameter smaller the blower tube 8a. As shown in FIGS. 2, 4, 7, and 8, the upper part of the water pipe 7a is inserted in the upper-intermediate part of the blower tube 8a. The distal end of the upper part of the water pipe 7a so inserted protrudes to the inside of the defecation tube 2b from the top end of the blower tube 8a, being oriented toward the upper end of the defecation tube 2b. Particularly, as shown in FIG. 8, the bottom end of the water pipe 7a is connected to a pump unit 7p accommodated in the washing-water tank 7. The pump unit 7p pumps the warm washing-water in the washing-water tank 7 to feed to the buttocks in the diaper cover 1. Thus, the water pipe 7a forms a washing-water feeding path to the buttocks in the diaper cover 1. In the intermediate part of the water pipe 7a, the detachable connectors, a connector 7a1 on one side and a connector 7a2 on the other side, are inserted. The water pipe 7a is separable from the washing-water tank 7 by releasing the connection between the connector 7a1 on one side and the connector 7a2 on the other side.

(38) The connector 7a1 on one side is the connector attached on the bottom end of the upper part of the water pipe 7a, which is shown in the right side portion of FIGS. 11(a) and 11(b). As shown in those figures, the connector 7a1 on one side comprises: a gripping sleeve 7a11 of plastic, an annular magnet 7a12 positioned inside the gripping sleeve 7a11 protruding by a predetermined distance from the end thereof, and the upper part of the water pipe 7a inserted in the annular magnet 7a12 from its back side to its middle point.

(39) The connector 7a2 on the other end is the connector shown in the left side portion of FIGS. 11(a) and 11(b). This connector comprises: a gripping sleeve 7a21 of plastic; a reversed polarity annular magnet 7a22 positioned inside the gripping sleeve 7a21 at the place recessed by a predetermined distance from the end thereof, the polarity of the annular magnet 7a22 being reverse to the polarity of the connector 7a12 on one side; and the lower part of the water pipe 7a inserted in the reversed polarity annular magnet 7a22 from its back side to the position protruding by the distance equal to the recess distance of the lower part of the water pipe 7a in the connector 7a1 on one side so as to be fixed there.

(40) As shown in FIGS. 1 and 3(b), the urine catching pad 3 is a belt-shaped component of a rectangular shape having an opening 3a in the center thereof; the material of this component is exactly equivalent to that in the existing ones. The opening 3a has a size slightly larger than the inner diameter of the defecation tube 2b of the feces receiver 2. The urine catching pad 3 is for absorbing moisture such as urine to prevent the skin of the wearer of the device from bad effects thereof and is a disposable item as with the other ones commonly used.

(41) The wastes container 4 is a container unit that collects feces, urine, and drainage of the washing-water wastes, and the bottom end of the feces and urine intake pipe 5 is connected thereto as shown in FIG. 8. The wastes container 4 has an exhaust port 4a having an adsorbent filter on its upper part for adsorbing bad smell component. The exhaust port 4a prevents bad smell emission during the taking-in the feces, urine, and the washing-water drainage allowing a smooth intake; the port also works as an exhaust opening of the drying air.

(42) The feces and urine intake pipe 5 is comprised of a funnel-shaped part 5a of its upper part and a straight pipe part 5b of its lower part, as shown in FIGS. 7, 8, 9(a), and 9(b). The bottom end of the feces and urine intake pipe 5 is connected communicatively to the upper part of the wastes container 4. In the upper-intermediate part of the straight pipe part 5b, the valve unit 6 is inserted. In a usual state, bad smell from the filth in the wastes container 4 does not spread because the upper and bottom end of the straight pipe part 5b are closed both in their positions. As shown in FIGS. 7, 8, 9(a), and 9(b), the funnel-shaped part 5a has one pair of an L-shaped connection metal fittings 5c on its uppermost peripheral side face and they are arranged at an interval of 180-degree; using this metal fittings, the funnel-shaped part 5a can be joined to the predetermined place on the bed.

(43) Particularly, as shown in FIGS. 9(a) and 9(b), each of vertical tongues 5c1 of the L-shaped connection metal fitting 5c are rotatably fitted, using a pin, on the upper peripheral side face of the funnel-shaped part 5a at an interval of 180-degree as stated above. Each of horizontal tongues 5c2 is pin-secured fixedly on the undersurface of a bed 10 as shown in FIG. 10. The funnel-shaped part 5a is fitted on the undersurface of the bed 10 as shown in FIG. 8 approximately aligning its axis with the axis of a defecation hole 10h that opens roughly in the center of the bed 10.

(44) As stated above and shown in FIGS. 7 to 10, the valve unit 6 is a valve mechanism inserted in the upper-intermediate part of the straight pipe part 5b of the feces and urine intake pipe 5. As shown in FIG. 9(a) particularly, the valve unit 6 basically has a valve box 6a that couples communicatively the upper and the lower part of the straight pipe part 5b and a plate-like valve member 6b each end of which is fitted rotatably to one side of the valve box 6a. The valve member 6b is usually biased by a biasing means, which is not illustrated in the figures, so that it is oriented in the direction orthogonal to the axis of the straight pipe part 5b. The spring constant of the biasing means is set to an extent either: the weight of the feces or the like when a minimum amount of such matter falls on the valve member 6b or the pressure of warm wind from the warm wind generating means 8 when the exhaust of drying air flows-in, whichever is smaller for causing the downward rotation of the valve member 6b. As the biasing means, this embodiment uses a coil spring that is wound on the rotary shaft on the rotating end of the valve member 6b.

(45) On the rotating end of the valve member 6b, a detection means, which is not illustrated in the figures, is provided to detect the rotation of the valve member 6b when the valve rotates downward to a certain angle, 50-degree or more in this embodiment. A detection signal detected by this detection means is sent to the control means 9 through a wire, which is not illustrated. Receiving the detection signal, the controller 9 judges that the bedridden aged or sick person defecated.

(46) As stated above and shown in FIG. 8, the washing-water tank 7 is a container for storing warm washing-water and accommodates the pump unit 9p for sucking the warm washing-water. Further, the tank is equipped with a warming unit, which is not illustrated, for warming the washing-water reserved in the tank. The pump unit 7p is connected to the water pipe 7a.

(47) As shown in FIG. 8, the warm wind generating means 8 is installed on the washing-water tank 7 in this embodiment and is a means for generating the warm wind to be sent to the buttocks wrapped in the diaper cover 1 through the blower tube 8a. Specifically in this embodiment, the warm wind generating means 8 comprises a blower, which is not illustrated, and a heater, which is not illustrated, for heating the wind generated by the blower.

(48) As shown in FIG. 8, the control means 9 is installed on the wastes container 4 in this embodiment. The control means 9 sends a pump-driving signal to the pump unit 7p in the washing-water tank 7 after a predetermined time, one minute and 30 seconds in this embodiment, from the reception of the detection signal which the detection means outputs on detection of the defecation by the detection means of the valve unit 6. Thereby, the control means 9 makes the pump unit 7p operate a pumping action of feeding 300 cc in 10 seconds. Further, after the pumping action of 10 seconds of the pump unit 7p completes, the control unit 9 sends a signal that makes the warm wind generating means 8 operate for two minutes, during which the warm wind is sent out. The warming unit, which is not-illustrated, of the washing-water tank is controlled to operate continuously so as to maintain the washing-water in the washing-water tank 7 at the preset temperature. The warming temperature of the washing-water can be set freely by the administrator of the device.

(49) The bed 10 to which the drop-type automatic excrement processing device in this embodiment is applicable is basically nothing different from those usual beds. However, the bed 10 has the defecation hole 10h approximately its center and requires attaching the funnel-shaped part 5a of the feces and urine intake pipe 5 on the undersurface thereof at the position corresponding to the defecation hole 10h using the L-shaped connection metal fittings 5c, as stated above. When a bed satisfies these features and the requirement, the device is settable on such bed.

(50) Thus, when the drop-type automatic excrement processing device in this embodiment is used in a manner as described below, the device exhibits an excellent effect as will be stated later.

(51) The feces receiver 2 and the urine catching pad 3 are fitted on the diaper cover 1 of this device, and then the diaper cover 1 so prepared is put on the buttocks of a bedridden objective aged or sick person lying on the bed 10.

(52) The diaper cover 1 is spread with its inside up as shown in FIG. 3(a), and the feces receiver 2 is put thereon as shown in FIG. 1. The feces receiver 2 is prepared in a manner as shown in FIG. 3(a), in which the belt-shaped rubber sheet part 2a is put on the bottom flap 1a of the diaper cover 1, the defecation tube 2b is inserted in the opening for defecation and urination 1h of the diaper cover 1, to penetrate below the cover, and the urine catching pad 3 is put on the belt-shaped rubber sheet part 2a aligning the axis of the opening 3a of the urine catching pad 3 and the axis of the defecation tube 2b of the feces receiver 2. The preparation steps further continue. The belt-shaped rubber sheet part 2a of the feces receiver 2 is drawn out on the urine catching pad 3, through the opening 3a of the urine catching pad 3, the belt-shaped rubber sheet part 2a is pulled toward outer edge of the bottom flap 1a of the diaper cover 1, and then the hook-and-loop fastener 2af on the outer surface of the outer edge of the belt-shaped rubber sheet part 2a is fastened to the hook-and-loop fastener 1aif on the inner surface of the bottom flap 1a.

(53) The diaper cover 1 having the feces receiver 2 and the urine catching pad 3 fitted on its inside in a manner as stated above is put on the buttocks of the bedridden aged or sick person lying on the bed 10 as shown in FIGS. 5 and 6. The diaper cover 1 prepared and spread with its inside up as shown in FIG. 1 is slid under the buttocks of the bedridden aged or sick person, and then the bottom flap 1a of the diaper cover 1 is folded back onto the underbelly of the bedridden aged or sick person; further, the wrapping flaps 1b and 1c on the both sides are folded back so that the underbelly is enveloped. In this embodiment, first, the wrapping flap 1c on the left side is folded back onto the bottom flap 1a applied on the underbelly, then the hook-and loop fastener 1cif on the inner surface of the wrapping flap 1c on the left side is fastened to the hook-and-loop fastener 1af on the outer surface of the bottom flap 1a; further, the wrapping flap 1b on the right side is folded back onto the wrapping flap 1c on the left side applied on the underbelly, and the hook-and-loop fastener 1bf on the inner surface of the wrapping flap 1b on the right side is fastened to the hook-and loop fastener 1cf on the outer surface of the wrapping flap 1c on the left side to complete putting on the diaper cover 1.

(54) When sliding the diaper cover 1 under the buttocks of the bedridden aged or sick person in the preparatory steps stated above, the defecation tube 2b of the feces receiver 2, the tube protruding pendently from the opening for defecation and urination 1h, should be inserted at the same time in the defecation hole 10h that opens roughly in the center of the bed 10.

(55) Meanwhile, the other components of this drop-type automatic excrement processing device should be installed under the objective bed 10 in advance. As shown in FIG. 8, the wastes container 4, the washing-water tank 7, the warm wind generating means 8 on the washing-water tank 7, and the control means 9 on the wastes container 4 are placed under the bed 10. The funnel-shaped part 5a of the upper part of the feces and urine intake pipe 5 risen from the wastes container 4 is fixed on the undersurface of the bed 10 using the pair of the L-shaped connection metal fittings 5c as stated above. The funnel-shaped part 5a is fitted on the bed 10 using the L-shaped connection metal fittings 5c, as shown in FIGS. 7, 8, and 10, mutually aligning the axes of the funnel-shaped part 5a and the defecation hole 10h of the bed 10 in a manner that allows relative slanting with respect to the longitudinal direction of the bed 10.

(56) Thus, under this situation, the defecation tube 2b inserted in the defecation hole 10h in the bed 10 becomes in a state of being inserted in the funnel-shaped part 5a on the uppermost part of the feces and urine intake pipe 5, with free relative movements in raising and lowering and in slanting allowed. The blower tube 8a and the water pipe 7a are draw out below the bed 10 through the defection hole 10h in the bed 10, wherein the top end of blower tube 8a is connected to the upper-intermediate part of the defecation tube 2b and the water pipe 7a is inserted in the blower tube 8a at the upper-intermediate part thereof and is extended to near the uppermost end of the defecation tube 2b through inside the blower tube 8a. The connector 8a1 on the bottom end of the upper part of the blower tube 8a is connected to the connector 8a2 on the uppermost end of the lower part of the blower tube 8a so that the blower tube 8a is connected to the warm wind generating means 8. The connector 7a1 on one end on the bottom end of the upper part of the water pipe 7a is connected to the connector 7a2 on the other end on the upper end of the lower part of the water pipe 7a so that the water pipe 7a is connected to the washing-water tank 7 through the pump unit 7p.

(57) The drop-type automatic excrement processing device in use works as follows. When the bedridden aged or sick person, who wears the diaper cover 1 having the feces receiver 2 or other components thereon, defecates or urinates, the excrement falls into the funnel-shaped part 5a of the upper part of the feces and urine intake pipe 5 through the defecation tube 2b of the feces receiver 2 in the diaper cover 1. The excrement falling into that part slips down from there to reach the valve unit 6 provided on the upper-intermediate part of the straight pipe part 5b located below the feces and urine intake pipe 5 and the matter drops on the valve member 6b. When the excrement drops on the valve member 6b of the valve unit 6, the valve member 6b rotates downward due to the weight of the excrement on it. The excrement on the valve member 6b then falls down through the straight pipe part 5b below the valve unit 6 and is collected in the wastes container 4. Excrement in continuation is also collected in the wastes container 4 going through the same process as the above.

(58) When the excrement drops on the valve member 6b of the valve unit 6 and the valve member 6b rotates downward by more than a predetermined angle, that rotation is detected by a detection means, which is not illustrated. The detection signal issued by that detection means enters the control means 9. One minute and 30 seconds after the signal entering, the control means 9 sends a pump-driving signal to the pump unit 7p in the washing-water tank 7. Thereby, the control means 9 makes the pump unit 7p operate a pumping action of feeding 300 cc of washing-water in 10 seconds. With this pumping action, the warm washing-water in the washing-water tank 7 is sent to the buttocks, which is covered with the diaper cover 1, of the bedridden aged or sick person through the water pipe 7a and is jetted from the top end of the water pipe 7a to the buttocks. The washing-water in the washing-water tank 7 is always warmed to the predetermined temperature by the warming unit. The jetting is applied for 10 seconds as stated above and the buttocks is cleaned. The washing-water after use is collected also in the wastes container 4 flowing through the similar path to that for the excrement.

(59) After the washing of 10 seconds, the control means 9 sends a signal to the warm wind generating means 8 to drive for two minutes. Thereby, the warm wind generated by a blower and a heating means is fed to the buttocks, which is covered with the diaper cover 1, of the bedridden aged or sick person through the blower tube 8a to dry the buttocks.

(60) While the pumping action of the pump unit 7p in the washing-water tank 7 or the warm wind feeding action of the warm wind generating means 8 is in operation, the detection signal in detection of excrement outputted from the valve member 6 is ignored. Thereby, an unnecessary repetition of above-stated operating cycle caused by a detection signal generated from the valve unit 6 attributable to the flowing-down of the warm washing-water is avoided.

(61) As stated above, the inside of the diaper cover 1 is washed with warm washing-water and dried with warm wind immediately when the defecation or urination is detected by the valve unit 6 provided in the upper-intermediate part of the feces and urine intake pipe 5. Therefore, the buttocks and loins of the bedridden aged or sick person, who is the wearer of the device, as well as the feces receiver 2, etc. inside the diaper cover 1, are always maintained in a sanitary and dry condition.

(62) During these actions stated above, a mixture of the filth and washing-water flows down into the wastes container 4, causing the pushing out of the gas staying in the upper part of the container from the exhaust port 4a. The drying wind also passes through this container and is exhausted into air from the exhaust port 4a. In this exhaust, such gases are released with bad smell components removed by the filter in the exhaust port 4a; there is therefore no possibility of spreading the bad smell outside.

(63) As stated above, the defecation tube 2b of the feces receiver 2 protruding pendently from the undersurface of the diaper cover 1 is inserted in the funnel-shaped part 5a of the upper part of the feces and urine intake pipe 5 risen from the wastes container 4, with free relative movement in raising and lowering and in slanting allowed. Even if the bedridden aged or sick person who wears the diaper cover 1 moves due to various reasons, the connection relation between the defecation tube 2b and the funnel-shaped part 5a can adapt freely to such movement; no troubles therefore will happen. The bedridden aged or sick person wearing the diaper cover 1 can move freely to some extent, wearing it on.
