The separator 202 (that is, the exit of the excretion tank 200) includes an air tube 140, a deodorization / sterilizer. 207 and the air pipe 141 are connected to the suction port of the blower blower 205. On the other hand, an air pipe 143, a branch pipe 144, and an air pipe 145 are sequentially connected to the discharge port of the blower blower 205, and the air pipe 145 is connected to the blower hose connection port 124 (FIG. 6) via the blower hose. . Thereby, air is supplied into the diaper 12 through the cleaning port 134a. An air pipe 150, a two-way valve 218, an air pipe 151, and a branch pipe 170 are sequentially connected to the branch destination of the branch pipe 144 inserted between the air pipe 143 and the air pipe 145.

  210 is a washing water tank for storing washing water. A warm water heater 211 that warms the stored wash water is provided at the bottom of the wash water tank 210, and a thermistor 212 that detects the temperature of the stored wash water is provided inside the wash water tank 210. A float sensor (water level meter) 213 for detecting the amount of cleaning water is provided, and the amount of stored cleaning water and its water temperature can be monitored. An inlet (not shown) is provided in the upper part of the cleaning water tank 210, and when cleaning water is supplied to the cleaning water tank 210, it is injected from the inlet. In addition, a water pipe 147 having a drain cock (stopcock) 214 is connected to the lower part of the washing water tank 210. When the washing water is drained from the washing water tank 210, the drain cock 214 is opened and the water pipe 147 is washed. Allow water to flow out. Further, a water pipe 148, a water pump 215, a water pipe 149, a branch pipe 170, and a water pipe 152 are sequentially connected to the water outlet provided in the washing water tank 210. The water pipe 152 is connected to the cleaning water hose connection port 123 (FIG. 6) via the cleaning water hose 17. Accordingly, cleaning water is supplied into the diaper 12 through the cleaning ports 130a and 130b.

  The excrement disposal apparatus 14 includes a control unit 216 that controls the entire excrement disposal apparatus 14, and the control unit 216 controls the blower blower 205, the hot water heater 211, the water pump 215, the two-way valve 218, and the like. Is done.

  Next, operation | movement of the excrement processing apparatus 14 is demonstrated, referring FIG.6 and FIG.7. The two-way valve 218 is closed in the initial state.

  This operation is roughly divided into three processes, a suction process, a cleaning process, and a draining process.

  First, the suction process is an operation of sucking excrement and the like from the diaper 12, and the control unit 216 opens the two-way valve 218 and operates the blower blower 205. As a result, the air inside the excretion tank 200 is sucked by the blower blower 205 and kept at a negative pressure, and the filth suction hose 16, the excretion tank 200, and the blower blower from the filth suction hose connection port 122 provided in the filth collection tray 120. While air flows toward 205, air circulates in the diaper 12 from the discharge port of the blower blower 205 through the air pipe 143, the air pipe 145, the blower hose 18, and the cleaning port 134 a.

  At this time, when the control unit 216 operates the water pump 215, the cleaning water flows from the cleaning water tank 210 to the air pipe 145 through the water pipe 148, the water pipe 149, the branch pipe 170, and the two-way valve 218. This is because the pressure loss is low because the opening area of the cleaning port 134a is larger than the small holes provided in the cleaning ports 130a and 130b as described above. And in the state which the said washing water and air were mixed in this air pipe 145, it is sent to the diaper 12 via the ventilation hose 18, and it raises the fluidity | liquidity of a filth by being injected from the washing port 134a. It is for sucking filth.

  More specifically, when the blower blower 205 is operated, the excretion tank 200 is maintained at a negative pressure, and only the air in the excretion tank 200 is guided to the air pipe 140 by the separator 202 and is converted into air by the deodorizer / sterilizer 207. The contained odor is removed and sterilized, and flows into the suction port of the blower blower 205. Further, the air discharged from the discharge port of the blower blower 205 is odor and sterilized as described above, and is guided into the diaper 12 so that the inside of the diaper 12 is kept hygienic.

  Next, the cleaning process is an operation of cleaning each part of the user 3. First, the control unit 216 operates the blower blower 205. As a result, the air inside the excretion tank 200 is sucked by the blower blower 205 and kept at a negative pressure, and the filth suction hose 16, the excretion tank 200, and the blower blower from the filth suction hose connection port 122 provided in the filth collection tray 120. While air flows toward 205, air circulates in the diaper 12 from the discharge port of the blower blower 205 through the air pipe 143, the air pipe 145, the blower hose 18, and the cleaning port 134 a.

  At this time, by operating the water pump 215, the cleaning water is sprayed from the cleaning water tank 210 through the water pipe 148, the water pipe 149, the branch pipe 170, and the cleaning water hose 17 from the cleaning ports 130a and 130b of the diaper 12. That is, in this cleaning process, in order to suck cleaning water from the diaper 12, air circulation similar to the air circulation in the above-described suction process is also performed.

  The draining process is an operation of draining the cleaning water accumulated in the cleaning water hose 17, and the control unit 216 opens the two-way valve 218 after the cleaning process is finished (that is, after the water pump 215 is stopped), and blows air. The blower 205 is operated. Thereby, a part of the air discharged from the blower blower 205 is guided to the washing water hose 17 through the branch pipe 144, the air pipe 150, the two-way valve 218, the air pipe 151, the branch pipe 170, and the water pipe 152. The washing water accumulated in the washing water hose 17 can be drained. Thereby, the low temperature water collected in the water pipe at the start of the next cleaning can be reduced, and the low temperature cleaning water ejected to the user 3 can be reduced.

  By the way, the cup 121 of the accommodation cup 110 of the diaper 12 is formed in a substantially curved shape as shown in FIGS. The cup 121 is formed by three-dimensionally stitching this material using a stretchable material (for example, a super composite skin). In this configuration, as shown in FIG. 8, the stretchable material 160 is cut into a shape including a base portion 161 and a plurality of pieces 162 to 165 extending from the base portion 161, and adjacent pieces are separated from each other. The cup 121 is formed by stitching. Specifically, the curved portion 162a of the first piece 162 and one curved portion 163a of the second piece 163 are stitched together, the other curved portion 163b of the second piece 163, and the third piece One curved portion 164a of the 164 is stitched, and the other curved portion 164b of the third piece 164 and the curved portion 165a of the fourth piece 165 are stitched. According to this, as shown in FIG. 9, the cup 121 includes a first stitching portion 166 that stitches the first piece 162 and the second piece 163, and the second piece 163 and the third piece 164. A second stitched portion 167 stitched and a third stitched portion 168 stitched between the third piece 164 and the fourth piece 165 are provided, and the cup 121 is curved in a substantially bowl shape as shown in FIG. It is formed.

  However, when the cup 121 is formed by stitching the stretchable material 160, sewage or the like may leak from the first to third stitching portions 166 to 168. Therefore, in order to prevent this, the inner surface of the cup 121 is subjected to water repellent processing. The water-repellent processing is performed, for example, by subjecting the stretchable material 160 to a titanium metal special surface processing (mesel structure). Since this titanium metal special surface treatment has a water repellent effect and an antibacterial effect, in this configuration, the inner surface of the cup 121 is subjected to a water repellent finish and an antibacterial finish treatment. According to this, since leakage from the stitching portions 166 to 168 of the cup 121 is eliminated, adhesion of sewage and the like to the inner surface of the cup 121 is prevented, so that growth of bacteria such as bacteria is prevented in the cup 121. (Antibacterial effect), the inside of the cup 121 can be kept hygienic. Furthermore, this water-repellent treatment has a characteristic of high heat retention effect and excellent stretchability.

  The waste collection tray 120 is formed of a resin such as plastic having a certain degree of hardness. For this reason, it is possible to easily form the connection portion 125 having the filth suction hose connection port 122, the washing water hose connection port 123, and the blower hose connection port 124 in the filth collection tray 120. The connection with the connection member 19 to which the hoses 16, 17, 18 are fixed can be reliably performed. Furthermore, it is possible to easily and reliably execute suction of excrement stored in the waste collection tray 120 and cleaning of the waste collection tray 120.

  The waste collection tray 120 and the cup 121 are connected by adhesion or the like. Moreover, the diaper 12 is formed by connecting the waste collection tray 120 and the back pad 12b by bonding or the like, and connecting the cup 121 and the stomach pad 12a by sewing or the like.

  The mat 10 on which the user lies is provided with an accommodation through hole 102 for accommodating the filth collection tray 120 as shown in FIG. When the user wears the diaper 12 and lies on the mat 10, the filth collection tray 120 of the diaper 12 is accommodated in the accommodation through hole 102, so that the weight of the user is directly applied to the filth collection tray 120. This prevents the user from feeling uncomfortable.

  As described above, the accommodation cup 110 of the diaper 12 includes the filth collection tray 120 and the cup 121, and the diaper 12 is mounted as compared with the conventional one by forming the cup 121 with a stretchable material. Since the tightening feeling of the cup 121 with respect to the local area is reduced, the diaper 12 and the excrement collection system 1 can be comfortably used for a long time.

  Moreover, the diaper 12 is equipped with the leak prevention member 123 in this diaper 12, as shown in FIG. The leakage prevention member 123 is provided so as to border the periphery of the cup 121 and the filth collection tray 120. When the user wears the diaper 12, the user's body and the leakage prevention member 123 come into close contact with each other. This prevents the waste and sewage in the cup 121 and the filth collection tray 120 from leaking out of the diaper 12. The leakage prevention member 123 has a certain degree of elasticity and elasticity, and fits to the user's body and reduces the user's floor slip.

  FIG. 12 is a partial cross-sectional view showing a cross section of the diaper of FIG. 11 taken along arrow AA ′. As shown in FIG. 11, the leakage preventing member 123 includes an outer surface material 123a that covers the outside, and a cushion material 123b that is included in the outer surface material 123a. The outer surface material 123a is formed of a stretchable foamed synthetic resin (for example, foamed neoprene) used for wet suits, and the surface thereof is waterproofed. The cushion material 123b is formed of an elastic material (for example, low-resilience urethane foam). In this configuration, the leakage prevention member 123 is formed by sandwiching the cushion material 123b between the two outer surface materials 123a and fixing both edges 170 and 171 of the two outer surface materials 123a by stitching or bonding. Yes. The leakage prevention member 123 formed in this way is arranged around the cup 121 and the filth collection tray 120, and is fixed to the belly pad portion 12a and the back pad portion 12b by sewing or bonding at the arranged positions.

  When the weight of the user 3 is applied to the leakage prevention member 123, both the outer surface material 123a and the cushion material 123b are crushed, but thereafter, the outer surface material 123a and the cushion material 123b gradually swell in accordance with the body of the user 3, thereby preventing leakage. The member 123 has a shape that fits the body of the user 3. That is, even when the user 3 operates, the leakage prevention member 123 is deformed so as to fit the body of the user 3 according to the operation, so that the leakage prevention member 123 and the user 3 Since the body is in close contact, excrement or sewage in the filth collection tray 120 can be prevented from leaking to the outside of the diaper 12 through the gap between the leakage prevention member and the body. Further, since the leakage preventing member 123 includes a cushioning material 123b having elasticity, the leakage preventing member 123 does not press the body of the user 3 more than necessary, and is tightened when the user 3 wears the diaper 12. The feeling can be reduced. Therefore, the floor slip of the user 3 can be prevented.

  According to the present embodiment, the accommodation cup 110 of the diaper 12 includes the filth collection tray 120 and the cup 121, the filth collection tray 120 is formed of resin, and the cup 121 is formed of a flexible soft material. Therefore, the suction of the excrement in the filth collection tray 120 and the cleaning in the filth collection tray 120 can be easily and reliably performed, and even when the diaper 12 is mounted, the cup 121 can be used locally. The feeling of tightening is reduced. Further, since the inner surface of the cup 121 has been subjected to water-repellent processing and antibacterial processing, leakage from the stitching portions 166 to 168 of the cup 121 is eliminated, and adhesion of sewage to the inner surface of the cup 121 is prevented. Bacteria growth on the inner surface of the cup 121 is prevented, and the inner surface can be kept hygienic. Therefore, excrement etc. do not remain, the inside of filth collection tray 120 and cup 121 (accommodating cup 110) can be kept clean, and user 3 should use diaper 12 and excrement disposal system 1 comfortably for a long time. Can do.

  Moreover, according to this embodiment, the leak prevention member 123 is arrange | positioned around the cup 121 of the diaper 12, and the filth collection tray 120, and this leak prevention member 123 stretches the low-resilience urethane foam 123b which has elasticity. Since the foamed synthetic resin 123a expands and contracts in accordance with the movement of the user, the low-resilience urethane foam 123b fits the user 3's body. Since the leakage preventing member 123 and the body of the user 3 are in close contact with each other, the excrement or sewage in the waste collection tray 120 is discharged from the gap between the leakage preventing member 123 and the user's body. 12 can be prevented from leaking outside. Furthermore, the low-resilience urethane foam 123b having elasticity does not press the body of the user 3 more than necessary, and can reduce the feeling of tightening when the user 3 wears the diaper 12. Therefore, the bed slip of the user 3 can be prevented, and the user 3 can use the diaper 12 and the excrement disposal system 1 comfortably for a long time.

  In addition, since the leakage prevention member 123 is fixed to the abdomen pad portion 12a and the back pad portion 12b by stitching or adhesion, when the user wears the diaper 12, the leakage prevention member 123 is It is prevented from coming off from the contact part 12a and the back support part 12b, and leakage of excrement and sewage in the filth collection tray 120 is prevented.

  Note that the above-described embodiment is merely one aspect of the present invention, and the present invention is not limited to this, and can be arbitrarily modified within the scope of the present invention. For example, in this embodiment, a low-resilience urethane material is used as the cushion material 123b of the leakage preventing member 123. However, the present invention is not limited to this, and a flexible rubber material (dry polymer), a gel-like cold storage material (polymer) A water-absorbing polymer). Furthermore, it is good also as a structure which uses air (nitrogen) as a cushioning material, introduce | transduces high pressure air in an outer surface material as needed, and inflates the leak prevention member 123. FIG.

  In the present embodiment, the cup 12 of the diaper 12 is formed by sewing a stretchable soft material into a substantially hook shape. However, the present invention is not limited thereto, and is formed by integrally molding the soft material. You may do it. According to this, since the number of work steps is reduced as compared with that formed by stitching, the manufacturing cost is reduced and the probability of leakage from the stitched portion is eliminated, so that the quality of the cup can be improved. Moreover, in this embodiment, although an example was shown as the shape before suturing which forms a cup, it is not restricted to this shape, If it is a substantially bowl-shaped cup formed by suturing, it is based on another shape It may be.
