At this time, the control unit 75 operates the water pump 54 e so that the cleaning water in the cleaning water tank 54 flows into the air pipe 65 through the water pipe 71, the water pipe 73, the branch pipe 69, and the two-way valve 67. This is because the pressure loss is low because the opening area of the cleaning port 34 is larger than the cleaning ports 30a and 30b as described above. And in the state which the said washing water and air were mixed in this air pipe 65, it is sent to the diaper 20 via the ventilation hose 6, and it raises the fluidity | liquidity of a filth by being injected from the washing | cleaning port 34. It is for sucking filth.
More specifically, when the blower blower 52 is operated, the excretion tank 51 is maintained at a negative pressure, and only the air in the excretion tank 51 is guided to the air pipe 61 by the separator 51b, and is converted into air by the deodorization / sterilizer 53. The contained odor is removed and sterilized, and flows into the suction port of the blower blower 52. Moreover, the odor and sterilization are performed as described above, and the air discharged from the discharge port of the blower blower 52 is guided into the diaper 20 so that the inside of the diaper 20 is kept hygienic.

Next, the cleaning process is an operation for cleaning each part of the user 2. First, the control unit 75 operates the blower blower 52. As a result, the air inside the excretion tank 51 is sucked by the blower blower 52 and kept at a negative pressure, and the filth suction hose 4, the excretion tank 51, the blower blower from the filth suction hose connection port 26 provided in the filth collection tray 24. While air flows toward 52, air circulates in the diaper 20 from the outlet of the blower blower 52 through the air pipe 63, the air pipe 65, the blower hose 6, and the cleaning port 34.
At this time, by operating the water pump 54 e, the cleaning water is sprayed from the cleaning water tank 54 through the water pipe 71, the water pipe 73, the branch pipe 69, and the cleaning water hose 5 from the cleaning ports 30 a and 30 b of the diaper 20. That is, in this cleaning process, in order to suck cleaning water from the diaper 20, 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 5, and the control unit 75 opens the two-way valve 67 after the cleaning process is finished (that is, after the water pump 54e is stopped), and blows air. The blower 52 is operated. Thereby, a part of the air discharged from the blower blower 52 is guided to the washing water hose 5 through the branch pipe 64, the air pipe 66, the two-way valve 67, the air pipe 68, the branch pipe 69, and the water pipe 74. The washing water accumulated in the washing water hose 5 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 2 can be reduced.

As described above, in this type of excrement disposal system, a diaper having a storage cup applied to the user's crotch and the excrement that is connected to the storage cup via the hose and sucks the excrement inside the storage cup. Since the treatment apparatus and the care mat on which the user lies are provided, excretion can be performed hygienically in a posture in which the user lies on the care mat. Therefore, the caregiver's care burden is reduced and the comfort of the user can be improved.
However, in the conventional one, since the hose connecting the storage cup and the excrement disposal device extends under the user's feet on the care mat, there is a problem that the user feels uncomfortable and impairs comfort. there were.
Then, even if it is a case where the diaper connected with the excrement disposal apparatus via the hose is mounted | worn, this invention is providing the care mat which a user can maintain comfort.

Next, the mat (care mat) 3 will be described.
FIG. 6 is an external perspective view showing the configuration of the mat 3. The mat 3 according to this configuration is a so-called urethane mat formed of urethane foam. As shown in FIG. 6, the mat 3 is formed of three parts (each having a substantially rectangular shape for convenience of carrying). For example, it is divided into a head mat 81, a buttocks mat 82, and a leg mat 83).
Between the head mat 81 and the butt mat 82, a first connector 84 for connecting the head mat 81 and the butt mat 82 is provided. The first connector 84 has one end 84A stitched to one of the head mat 81 or the buttocks mat 82 (for example, the buttocks mat 82), and the other end 84B to the other of the head mat 81 or the buttocks mat 82 ( For example, a fastening surface for fastening with a head mat 81) and a Velcro fastener is formed.
Further, a second connector 85 for connecting the butt mat 82 and the leg mat 83 is provided between the butt mat 82 and the leg mat 83. One end 85A of the second connector 85 is sewn to one of the butt mat 82 or the leg mat 83 (for example, the butt mat 82), and the other end 85B is connected to the other of the butt mat 82 or the leg mat 83 ( For example, a fastening surface for fastening with a leg mat 83) and a Velcro fastener or the like is formed. In the present embodiment, the leg mat 83 is connected to the collar mat 82 with a predetermined interval W.

The saddle mat 82 is formed with an accommodation through hole (hole) 86 for accommodating the accommodation cup 23 (FIG. 2) of the diaper 20 at a substantially central portion of the collar mat 82. When the user wears the diaper 20 and lies on the mat 3, the accommodation cup 23 is accommodated in the accommodation through hole 86, so that the weight of the user is directly applied to the accommodation cup 23 (particularly, the filth collection tray 24). This prevents the user from feeling uncomfortable.
Further, the mat 3 includes a groove portion 87 that communicates with the accommodation through hole 86 and is formed along the short direction of the mat 3. The groove 87 is for arranging the hoses 4 to 6 for connecting the accommodation cup 23 accommodated in the accommodation through-hole 86 and the excrement disposal apparatus 50. In the present embodiment, the flange mat 82 is provided. A rectangular space W provided between the leg mat 83 and the leg mat 83 functions as the groove 87. The predetermined interval W only needs to have a width sufficient to arrange the hoses 4 to 6.
Further, the groove portion 87 is formed at a position corresponding to a space between the user's thigh and knee in the mat 3 when the user lies on the mat 3. This is because when a person lies on the mat, the body pressure is hardly applied to the position corresponding to between the thigh and the knee. Thus, in this structure, the groove part 87 connected to the accommodation through-hole 86 is formed in the position corresponding to between the user's thigh and knee parts in the mat 3, and each of the hoses 4 to 6 is formed in the groove part 87. The hose 4 to 6 is prevented from extending under the user's feet on the mat 3 by arranging the hose. For this reason, the user does not feel uncomfortable and the user's comfort can be maintained.
Furthermore, since the upper part of the groove part 87 is open, even if the hoses 4 to 6 are connected to the accommodation cup 23 of the diaper 20 and the excrement disposal apparatus 50, the groove part 87 is not removed. Can be placed in.

In this configuration, as shown in FIG. 6, a first cover member 90 and a second cover member 91 that fit into the groove 87 are detachably disposed in the groove 87. The first cover member 90 and the second cover member 91 are made of urethane foam in the same manner as the mat 3, and are formed at substantially the same height as the groove 87.
The first cover member 90 includes a concave portion 90A formed along the longitudinal direction of the first cover member 90, and is formed in a substantially U-shaped cross section. The first cover member 90 is disposed in the groove portion 87 on the side where the excrement disposal apparatus 50 is disposed, that is, the side where the hoses 4 to 6 are led out, with the concave portion 90A facing downward. According to this, since each hose 4 thru | or 6 is derived | led-out outside the mat 3 through the space enclosed by the 2nd connector 85 and the recessed part 90A, each hose 4 thru | or 6 extends on the mat 3. This can be prevented and the step caused by the groove 87 can be eliminated. Further, since the second cover member 91 is formed in a substantially rectangular parallelepiped shape and is disposed in the groove portion 87 on the side where the first cover member 90 is not disposed, the step generated by the groove portion 87 can be eliminated.
Further, since the first cover member 90 and the second cover member 91 are detachably disposed in the groove portion 87, even after the user lies on the mat 3 and each hose 4 to 6 is disposed in the groove portion 87. The first cover member 90 and the second cover member 91 can be easily fitted into the groove portion 87. Furthermore, the positions of the first cover member 90 and the second cover member 91 can be easily exchanged according to the position of the excrement disposal apparatus 50.

By the way, the nursing bed 7 (FIG. 1) on which the mat 3 is placed tilts the back portion 7A that supports the back of the user 2 in order to raise the upper body of the user 2 during a meal or the like ( Gatch up). In this case, when the upper body of the user 2 is raised, the weight of the user 2 is mainly added to a position corresponding to the buttocks of the mat 3, and the thickness of the portion corresponding to the buttocks is reduced. Further, the filth suction hose 4 connected to the storage cup 23 extends from the crotch toward the leg, and has such rigidity that the excrement disposal apparatus 50 does not change the tube diameter even if the sewage treatment device 50 sucks the filth by the air pressure difference. Therefore, if the upper body of the user 2 is raised, the filth suction hose 4 may come into contact with the frame of the care bed 7 and cause the user 2 to feel uncomfortable.
In this configuration, the depth H of the mating through-hole 86 of the mat 3 (that is, the thickness of the mat 3) is such that the filth suction hose 4 contacts the frame of the care bed 7 even when the upper body of the user 2 is raised. The depth is set so as not to contact (specifically, about 130 mm). For this reason, it is possible to prevent the user from feeling uncomfortable due to the filth suction hose 4 coming into contact with the frame of the bed 7 and maintain the user's comfort.

FIG. 7 is a cross-sectional view of the mat 3. In FIG. 7, the head mat 81 constituting the mat 3 is shown, but the heel mat 82 and the leg mat 83 are also the same as the head mat 81.
The mat 3 (head mat 81) is configured by laminating and arranging a plurality of (three in this embodiment) urethane mats having different hardnesses. In this configuration, the lower layer mat 81A is formed of the hardest material (for example, chip urethane), and the lower layer mat 81A is sequentially changed to the middle layer mat 81B (for example, highly elastic urethane) and the upper layer mat 81C (for example, low resilience urethane). It has become softer. In this configuration, the ratio of the thicknesses t1, t2, and t3 of the lower layer mat 81A, the middle layer mat 81B, and the upper layer mat 81C is set to be approximately 2: 2: 9.
The ratio of the hardness and thickness of each of the mats 81A, 81B, 81C is determined based on a number of experiments. As described above, the mat 3 includes the lower layer mat 81A, the middle layer mat 81B, and the upper layer mat 81C. By forming each of the mats 81A to 81C so as to become the upper layer sequentially, the dispersibility of the body pressure can be improved. The floor slip is less likely to occur when the user lies on the mat.

  According to this embodiment, when the user 2 wears the diaper 20 and lies on the mat 3, the weight of the user 2 is directly accommodated by accommodating the accommodation cup 23 of the diaper 20 in the accommodation through hole 86. Since it is prevented from being applied to the cup 23, the user 2 does not feel uncomfortable. Further, the mat 3 is provided with a groove portion 87 that communicates with the accommodation through hole 86, and the hoses 4 to 6 are disposed in the groove portion 87, so that the hoses 4 to 6 extend on the mat 3 to the feet of the user 2. It is prevented. For this reason, the user 2 does not feel uncomfortable and the comfort of the user 2 can be maintained.

  Moreover, according to this embodiment, since the groove part 87 is provided along the transversal direction of the said mat 3 in the position corresponding to between the thigh part of the user 2 and a knee part, in this groove part 87, Since the body pressure of the user 2 is hardly applied, it is possible to prevent the user from feeling uncomfortable with the groove 87.

Further, according to the present embodiment, the first cover member 90 that covers the groove portion 87 in a state where the hoses 4 to 6 are disposed is disposed in the groove portion 87, and thus the hoses 4 to 6 are connected to the groove portion 87. Since the lead is led out to the outside of the mat 3 through the space surrounded by the first cover member 90, the hose 4 to 6 can be prevented from extending on the mat 3, and the level difference caused by the groove 87 is eliminated. Can do.
Moreover, since the mat 3 is formed by laminating and arranging a plurality of urethane mats having different hardnesses, the body pressure applied to the mat 3 can be effectively dispersed. Moreover, since this mat 3 is a urethane mat, the accommodation through-hole 86 and the groove part 87 can be formed easily.

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 cushioning material 43 of the leakage preventing member 41. 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, encloses air in the outer surface material 42 as needed, and makes the leakage prevention member adhere to the user's body.
Further, in the present embodiment, the mat 3 includes a split butt mat 82 and a leg mat 83, and the leg mat 83 is connected to the butt mat 82 with a predetermined interval W so that the interval is set. Although W is functioning as the groove portion 87, the present invention is not limited to this, and the groove portion may be formed on the mat.
