Description

[Technical Field]

[0001] The present invention relates to a cup for an automatic excretion disposal device and an automatic excretion disposal device for automatically disposing of excrement from a person requiring care. [Background technology]

[0002] In recent years, the number of people requiring care, such as elderly people and physically disabled people, who require assistance with excretion, has been increasing year by year. While the number of people requiring care is increasing, there is a chronic shortage of caregivers. This trend is expected to become even more pronounced in the future. For caregivers, dealing with the excretion of people requiring care is the greatest burden. Automatic excretion disposal devices have been proposed to assist such people requiring care with excretion and reduce the burden on caregivers.

[0003] The applicant has already proposed an automatic excretion disposal device and a cup for the automatic excretion disposal device that dispose of excrement from a person requiring care (see, for example, Patent Documents 1 and 2). The automatic excretion disposal device comprises a cup that is attached to the body of the person requiring care, a drainage device that sucks up excrement in the cup and discharges it into a sewer pipe, and a washing device that supplies cleaning water from the water supply to wash the inside of the cup and the body. The automatic excretion disposal device described in Patent Document 1 can automatically supply water to wash the body of the person requiring care during excretion disposal, and automatically discharge excrement into the sewer.

[0004] [Patent Document 1] Patent No. 6635456 [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-153950 Summary of the Invention [Problem to be solved by the invention]

[0005] A person requiring care spends a day in a variety of positions, such as lying down, tossing and turning, or tilting the bed to raise the upper body. When the person requiring care is in one of the above positions, a gap may form between the cup that collects the excrement and the person's body, potentially resulting in leakage of excrement and odors during excrement disposal. According to the technology described in Patent Document 1, even if a gap occurs between the cup and the body, air is sucked through the gap, thereby preventing leakage during excrement disposal. Through extensive research, the inventors have made further improvements to more reliably prevent leakage during excrement disposal.

[0006] An object of the present invention is to provide a cup for an automatic excretion disposal device and an automatic excretion disposal device that can reduce leakage even if the posture of a person requiring care changes during excretion disposal. [Means for solving the problem]

[0007] One aspect of the present invention is a cup for an automatic excretion disposal device that is provided in an automatic excretion disposal device that automatically processes the excretion of a person requiring care, and includes a cup body that is attached to the body of the person requiring care and receives excreta, and an expansion body that is provided on the cup body and expands when a working fluid is supplied thereto and fits closely to the contact part of the body, and the cup body is formed with a first bottom that is formed to contact the installation surface when the body is in a supine position, and a second bottom that is formed continuously with the first bottom at a dihedral angle and is formed to contact the installation surface when the body is in a semi-sitting position.

[0008] According to the present invention, the first bottom portion contacts the installation surface when the body is in a first supine position, thereby stably fixing the body to the seat, and the second bottom portion contacts the installation surface when the body is in a second semi-sitting position, thereby stably fixing the body to the seat, thereby reliably preventing leakage of excrement. [Effects of the Invention]

[0009] According to the present invention, leakage during excretion treatment using an automatic excretion treatment device can be reduced. [Brief explanation of the drawings]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic excretion disposal device according to the present invention will now be described with reference to the drawings. The automatic excretion disposal device automatically disposes of excretion for a person requiring care.

[0012] As shown in Figures 1 and 2, the automatic excretion disposal device 1 comprises a cup 2 (cup for the automatic excretion disposal device) that is attached to the body of the person requiring care, and a main body device 20 for cleaning the inside of the cup 2. The automatic excretion disposal device 1 is configured in accordance with the automatic excretion disposal device described in Patent Document 1. The automatic excretion disposal device 1 is not limited to this and may have other device configurations. The main body device 20 and the cup 2 are connected by a single hose H.

[0013] The main device 20 includes a cleaning device 24 that receives water from the water supply and cleans the inside of the cup 2 and the body of the person requiring care, a drainage device 26 that discharges the cleaning water and wastewater containing excrement discharged from the cup 2 into a sewer pipe, an air supply device 28 that supplies air into the cup 2, and a control device 22 that controls the operation of each device.

[0014] The cup 2 comprises a detector 3 for detecting excrement, a cup body 6 attached to the crotch area of ​​the care recipient, and an inflatable body 10 provided between the cup body 6 and the body of the care recipient.

[0015] Control device 22 is electrically connected to detection unit 3, which will be described later and is provided in cup 2. Based on the detection value of detection unit 3, control device 22 controls cleaning device 24, drainage device 26, and air supply device 28 to supply water to the inside of cup 2, drain wastewater containing excrement, and clean and dry the inside of cup 2.

[0016] The control device 22 comprehensively controls the cleaning device 24, the drainage device 26, and the air supply device 28, and executes the excretion treatment cycle. The control device 22 is realized by a processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these functional units may be realized by hardware such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field-Programmable Gate Array), or may be realized by a combination of software and hardware.

[0017] The cleaning device 24 is connected to the cup body 6 by a water supply pipe Q (first pipe). The cleaning device 24 is controlled based on the detection value of the detection unit 3, and supplies cleaning water from a water supply to the inside of the cup 2 via the water supply pipe Q. A clean water pipe 24A that supplies clean water from the water supply is connected to the cleaning device 24. The cleaning device 24 includes, for example, a solenoid valve (not shown). The cleaning device 24 opens the solenoid valve, for example, to allow clean water to flow to the downstream water supply pipe Q based on the water pressure applied to the clean water pipe 24A. The cleaning device 24 closes the solenoid valve to stop the supply of clean water. The cleaning device 24 may be provided with a pressure reducing valve (not shown) that adjusts the water pressure applied to the clean water pipe 24A. The solenoid valve may be a proportional solenoid valve that can arbitrarily adjust the amount of clean water supplied.

[0018] Cleaning device 24 starts operation based on the detection value of detection unit 3, and supplies a set amount of cleaning water to cup 2. Cleaning device 24 starts supplying cleaning water into cup 2 at a predetermined timing based on the detection value of detection unit 3, and stops supplying cleaning water at a predetermined timing after the start of supply. Cleaning device 24 may supply disinfectant into cup 2 in conjunction with the supply of cleaning water. The disinfectant may be supplied to water supply pipe Q, or may be supplied into cup 2 through a pipe separate from water supply pipe Q.

[0019] Drainage device 26 is connected to cup body 6 via drain pipe D (second piping). Drainage device 26 is controlled based on the detection value of detection unit 3. Drainage device 26 is equipped with a pump (not shown) and sucks up and drains wastewater containing excrement from cup 2 via drain pipe D. Drainage device 26 exhausts air circulating within cup 2 via drain pipe D. Drainage device 26 starts suction at a predetermined timing based on the detection value of detection unit 3, and stops suction at a predetermined timing after the start of supply or based on the detection value of detection unit 3.

[0020] The drainage device 26 sucks dirty water from inside the cup 2 through the drain pipe D and drains it outside the cup 2, discharging the dirty water into the sewer. The drainage device 26 sucks air from inside the cup 2 through the drain pipe D and exhausts it outside the cup 2, discharging some of the air into the sewer. The drainage device 26 may take the air sucked in from inside the cup 2 into the main device 20, deodorize it, and then supply it back to the cup 2, circulating air between the main device 20 and the cup 2. A drain pipe 24B for draining dirty water into the sewer is connected to the downstream side of the drainage device 26.

[0021] The air supply device 28 is connected to the cup body 6 via air supply pipes A1 and A2. The air supply pipes A1 and A2 may be shared by a single pipe. In this case, the air supply pipes A1 and A2 may be provided separately within the cup 2. The air supply pipes A1 and A2 may be configured with the internal space of the hose H as a flow path. In this case, the air supply pipes A1 and A2 may not be provided inside the hose H. In this case, the air supply pipes A1 and A2 may be provided separately within the cup 2. In the automatic excretion disposal device 1 of this embodiment, the internal space of the hose H is configured as a flow path, and the air supply pipes A1 and A2 are not provided inside the hose H. This allows the automatic excretion disposal device 1 to simplify the connection structure between the main body device 20 and the hose H.

[0022] Air supply device 28 is controlled based on the detection value of detection unit 3, and supplies air to the inside of cup body 6 during excretion processing. Air supply device 28 is equipped with an air pump (not shown), and supplies air to cup 2 via air supply pipes A1 and A2. After excrement has been discharged from cup 2 and it has been cleaned, air supply device 28 supplies air to the inside of cup 2 via air supply pipe A1, drying the inside of cup 2 and the body of the person requiring care. Air supply device 28 is also connected to expandable body 10 via air supply pipe A2.

[0023] The air supply device 28 is controlled based on the detected value and supplies air to the inside of the expandable body 10. The air supply pipe A2 may be provided inside the cup 2, branching off from the air supply pipe A1. A valve (not shown) may be provided between the air supply pipe A1 and the air supply pipe A2. The valve is, for example, a solenoid valve whose opening and closing is controlled by the control device 22 to adjust the amount of air supplied. The valve may also be a proportional solenoid valve whose opening and closing amount is optionally adjusted.

[0024] With the above configuration, excrement is temporarily received inside cup 2, and cleaning water is supplied from the water supply by cleaning device 24 to clean the body of the care-requiring person and the inside of cup 2. In cup 2, the cleaning water, excrement, and air inside the cup are discharged into the sewer by drainage device 26. After cleaning, air is supplied to cup 2 by air supply device 28, and the washed body of the care-requiring person and the inside of cup 2 are dried.

[0025] The cup 2 is attached to the body of the person requiring care and includes a cup body 6 for receiving excrement. Inside the cup body 6, for example, a detection unit 3 for detecting excrement is provided. The detection unit 3 and the control device 22 are electrically connected by an electrical cable C. The detection unit 3 is a capacitance sensor that electrically detects the capacitance inside the cup. The detection value of the detection unit 3 is output to the control device 22. Based on the detection value of the detection unit 3, the control device 22 determines whether the excrement is solid or liquid. Based on the detection result of the detection unit 3, the excrement processing cycle of the automatic excrement processing device 1 is started.

[0026] An expandable body 10 is provided between the cup body 6 and the body of the care recipient. The expansion of the expandable body 10 is controlled based on the detection value of the detection unit 3. When excrement is detected inside the cup body 6, the expandable body 10 is supplied with a working fluid, expands, and comes into close contact with the body of the care recipient. The working fluid is, for example, air supplied by an air supply device 28. The expandable body 10 eliminates any gap between the body of the care recipient and the cup 2 when disposing of the excrement, significantly reducing leakage of excrement.

[0027] Next, we will explain the specific shape of the cup 2. In the following explanation, the up-down direction of the cup 2 is defined in the state where the cup 2 is worn by the care-requiring person in a lying position.

[0028] 3 to 5, the cup 2 includes a cup body 6 formed to cover the crotch and anal area of ​​the care recipient, a body contact part 6D that comes into contact with the body of the care recipient, and a hose connection part H1 that is connected to a hose H. The cup 2 is usually placed in a first position in which the care recipient is lying on their back in a supine position. The cup 2 is attached to the body so that the direction of the tube axis L of the hose connection part H1 is approximately aligned with the left-right central axis of the body in a plan view.

[0029] The cup body 6 is formed to receive excrement and discharge wastewater, a mixture of excrement and cleaning water supplied from the cleaning device, to the outside. The cup body 6 includes, for example, a first container 6A that bulges out to cover the area around the crotch of the care recipient, and a second container 6B that is placed on a placement surface and covers the groin and anus area of ​​the care recipient. The first container 6A and the second container 6B are formed, for example, from resin.

[0030] The first container 6A bulges outward, forming an internal space. A protrusion 6T protruding outward is formed on the outer wall side of the first container 6A. The protrusion 6T is formed to extend in the vertical direction. A flow path (not shown) for circulating cleaning water and air is formed inside the protrusion 6T. At least one through hole 6W communicating with the inner wall side of the first container 6A is formed in the flow path. The cleaning water and air circulating in the flow path are supplied to the internal space through the through hole 6W. A water supply pipe Q and an air supply pipe A1 are connected to the flow path. The water supply pipe Q and the air supply pipe A1 are arranged inside a hose H.

[0031] A detection unit 3 (see FIG. 1) having one or more sensors is attached to the first container 6A and the second container 6B. The detection unit 3 detects changes in the volume of the internal space formed by the first container 6A and the second container 6B. Electrical wiring is connected to the detection unit 3. The electrical wiring is routed through the second container 6B into the hose H.

[0032] The second container 6B is disposed below the first container 6A. The lower part of the first container 6A is attached to the upper surface of the second container 6B. The bottom surface of the second container 6B is formed with a first bottom portion 6E formed to contact the installation surface and a second bottom portion 6F formed continuously with the first bottom portion 6E at a dihedral angle θ. The first bottom portion 6E is formed to contact the installation surface when the body is in a supine position. When the bed is tilted up from a supine position, the care-requiring person assumes a second semi-sitting position in which the lower half of the body is inverted on the bed and the upper half is raised. The second bottom portion 6F is formed to contact the installation surface when the body is in the second semi-sitting position.

[0033] An embossed anti-adhesion layer S having a plurality of dimple-shaped protrusions is formed on the inner wall of the second container 6B. The anti-adhesion layer S may be formed not only on the second container 6B but also on the inner wall of the first container 6A. The formation of the anti-adhesion layer S increases the gap between solid or semi-solid waste (subject to treatment) and the inner wall of the second container 6B, preventing adhesion between the waste and the inner wall of the second container 6B. The formation of the anti-adhesion layer S facilitates the flow of wash water and air between the waste and the inner wall of the second container 6B, promoting separation between the waste and the inner wall of the second container 6B and facilitating discharge of the waste outside the cup body 6.

[0034] By making it easier to discharge excrement outside the cup body 6, it is possible to shorten the time required for excrement treatment and thereby reduce the probability of leakage of treated water or excrement from the cup body 6. The anti-adhesion layer S may be formed by embossing or by debossing with concave dimples, or may be formed by a layer of a chemical substance that prevents adhesion, such as a fluororesin coating.

[0035] A body contact portion 6D that comes into contact with the body of the care recipient is provided around the first container 6A and the second container 6B and extends therefrom. The body contact portion 6D is formed of an elastic material such as silicone rubber. One side of the body contact portion 6D in a first region 6D1 around the first container 6A faces the outside space. An adhesive layer having adhesive properties is formed on the other side of the first region 6D1 that faces the body. The adhesive layer adheres to the body and elastically deforms to prevent gaps from forming between the body and the body. The adhesive layer may have adhesive strength comparable to that of adhesive tape, for example. The adhesive layer may be formed using double-sided tape or the like.

[0036] The second region 6D2 of the body contact portion 6D is formed, for example, to match the shape of the contact area of ​​the body. A pipe 10C that supplies air to the expandable body 10 is provided on one outer surface of the second region 6D2. An expandable expandable body 10 is provided on the other surface of the second region 6D2 that faces the body. The expandable body 10 is formed to match the shape of the second region 6D2. An inclined surface 10B that is inclined relative to the first bottom 6E is formed on the side of the expandable body 10 that contacts the body. The expandable body 10 expands and elastically deforms based on the inflow of working fluid, preventing the creation of a gap between the body contact portion 6D and the body. The configuration of the expandable body 10 will be described later.

[0037] The hose connection part H1 is formed in a tubular shape that protrudes from the cup body 6. The hose connection part H1 is attached so that the direction of the pipe axis L forms at least the dihedral angle θ with respect to the first bottom part 6E. It is sufficient that the hose connection part H1 is attached so that the direction of the pipe axis L forms an angle with respect to the first bottom part 6E that is equal to or greater than the dihedral angle θ. This makes it less likely that the hose H connected to the hose connection part H1 will interfere with the installation surface even when the person in need of care is in the first position or the second position, preventing deformation of the cup 2 and preventing excrement from leaking from within the cup 2.

[0038] The inclined surface 10B is formed at an inclination angle relative to the bottom surface of the second container 6B so that its width increases downward when viewed in cross section in the axial direction of the hose connection part H1. The inclined surface 10B is formed so as to come into contact with, for example, the intergluteal cleft of the buttocks of the body. The inclined surface 10B is formed to extend to fit the contact area including the intergluteal cleft and the base of the inner thigh.

[0039] As shown in FIG. 6, the expandable body 10 is provided on one side of the second region 6D2 of the body contact portion 6D. An inclined surface 10B is formed on one side of the expandable body 10. The inclined surface 10B is formed of a plate-shaped elastic material such as silicone rubber. An adhesive layer may be formed on the inclined surface 10B. A flow path 10S through which air flows is formed between the inclined surface 10B and the second region 6D2. Before the expandable body 10 is inflated, the inclined surface 10B elastically deforms to conform to the shape of the buttocks of the body and adheres closely to the body. When the expandable body 10 is inflated, the inclined surface 10B elastically deforms to adhere closely to the body side depending on the degree of inflation of the expandable body 10.

[0040] The expandable body 10 begins to expand at the start of the excretion process when the detection unit 3 detects excrement, and finishes expanding at the end of the excretion process when the excrement in the cup 2 is discharged outside the cup 2 and the body is completely dried. Air is supplied to the flow path 10S of the expandable body 10, and the inclined surface 10B deforms to bulge toward the body. When the expandable body 10 expands, the inclined surface 10B presses against the body, making close contact with the body and preventing excrement, cleansing water, etc. from leaking from the internal space of the cup 2.

[0041] With the above configuration, when the cup 2 is attached to the body of the care-requiring person, air is supplied from the air supply device 28 to the expandable body 10 during excretion processing, causing the expandable body 10 to expand. As the expandable body 10 expands, the inclined surface 10B is pressed against the body of the care-requiring person. The inflated expandable body 10 is flexible and deforms according to the physical condition of the care-requiring person, so that the inclined surface 10B fits tightly against the body of the care-requiring person without any gaps.

[0042] When the expandable body 10 is in an expanded state, excrement is treated inside the cup body 6, preventing the cleaning water, excrement, and even odors inside the cup body 6 from leaking to the outside. Furthermore, the expandable body 10 further expands due to the negative pressure generated inside the cup body 6 when excrement is sucked into the drain pipe D from inside the cup body 6 during excrement treatment. At this time, the degree of contact between the expandable body 10 and the body of the person requiring care is further increased, preventing gaps from being formed.

[0043] When the care recipient is in the first posture in the supine position, the first bottom 6E of the cup 2 is placed on a surface such as a bed. At this time, the expandable body 10 elastically deforms in accordance with the first posture of the care recipient. When the care recipient starts excretion processing in the first posture, the expandable body 10 expands, increasing the degree of contact with the body of the care recipient compared to when it is not expanded.

[0044] When the care recipient is in the second posture, semi-sitting, the second bottom 6F of the cup 2 is placed on a surface such as a bed. At this time, the expandable body 10 elastically deforms in accordance with the second posture of the body. When the care recipient starts excretion processing in the second posture, the expandable body 10 expands, increasing the degree of contact with the body of the care recipient compared to when it is not expanded.

[0045] Since the expandable body 10 elastically deforms to follow the shape of the body of the care recipient even when expanded, it prevents a gap from being created between the cup body 6 and the body of the care recipient even if the posture of the body of the care recipient changes due to the expansion of the expandable body 10. The expandable body 10 or the air supply pipe A2 may be provided with a regulator that adjusts the pressure of the air supplied from the air supply device 28.

[0046] After the excretion process is completed and the operation of the air supply device 28 is stopped, the expandable body 10 deflates as the air flows back through the air supply pipe A2. In other words, because the expandable body 10 is configured to expand during the excretion process, the burden on the body of the care recipient is reduced.

[0047] An electromagnetic valve or the like may be provided between the water supply pipe Q and the expansion water supply pipe, and the amount of flush water supplied to the expansion body 10 may be adjusted by the control device 22. The expansion body 10 may be provided with a discharge port that discharges flush water into the cup body 6. The discharge port may be formed by a hole with a diameter that discharges flush water while maintaining the water pressure inside the expansion body 10 within a predetermined range, or by a regulator.

[0048] As shown in Fig. 7, the main device 20 includes a box-shaped housing 20B. Internal devices such as a control device 22 (see Fig. 1) are provided inside the housing 20B. The housing 20B is made of, for example, a resin material. The housing 20B may also be made of a metal plate such as an aluminum plate. An operation unit 20C for operating the main device 20 is provided on the top surface side of the housing 20B. The operation unit 20C may be configured as a display screen displayed on a separately provided terminal device (not shown) capable of communication.

[0049] The front side of the housing 20B is provided with, for example, a hose connection H2 for attaching a hose H, a water supply pipe connection 24C for connecting a clean water pipe 24A, and a drain pipe connection 24D for connecting a drain pipe 24B. The hose connection H2 is detachably attached to the housing 20B. When the hose connection H2 is separated from the housing 20B, the electrical cable C, the water supply pipe Q, and the drain pipe D are separated. If air supply pipes A1 and A2 are provided inside the hose H, the electrical cable C, the water supply pipe Q, the drain pipe D, and the air supply pipes A1 and A2 may be configured to be separated when the hose connection H2 is separated from the housing 20B.

[0050] As shown in FIG. 8, the hose connection portion H2 includes a first hose connection portion H2A provided on the housing 20B side and a second hose connection portion H2B provided on the hose H side. The first hose connection portion H2A includes, for example, a circular ring H4 protruding outward from the housing 20B side. A plurality of claw portions H4T protruding radially are formed on the outer circumferential surface of the circular ring H4. A disk-shaped base H5 is provided inside the circular ring H4. The outer diameter of the base H5 is, for example, the same as the inner circumferential surface of the circular ring H4. The base H5 is provided with a connector C1 to which, for example, an electrical cable C is connected. The connector C1 is formed to protrude from the base H5. A plurality of electrical contacts E1 are provided inside the connector C1.

[0051] The base H5 is provided with a water supply pipe connection portion Q1 to which the water supply pipe Q is connected. In this embodiment, two water supply pipe connection portions Q1 are provided. The water supply pipe connection portion Q1 is formed in a cylindrical shape and protrudes from the base H5. A stepped portion Q1D that is reduced in diameter is formed on the inner peripheral surface of the water supply pipe connection portion Q1. A cylindrical gasket P1 is provided at the end of the stepped portion Q1D.

[0052] The base H5 is provided with an air supply pipe connection portion A3 to which the air supply pipes A1 and A2 are connected. In this embodiment, the air supply pipes A1 and A2 are integrated into one, and one air supply pipe connection portion A3 is provided. The air supply pipe connection portion A3 is formed in a cylindrical shape and protrudes from the base H5. A stepped portion A3D that is reduced in diameter is formed on the inner circumferential surface of the air supply pipe connection portion A3. A cylindrical packing P2 is provided at the end of the stepped portion A3D.

[0053] The base H5 is provided with a drain pipe connection portion D2 to which the drain pipe D is connected. The drain pipe connection portion D2 is formed in a cylindrical shape and protrudes from the base H5. A stepped portion D2D that is reduced in diameter is formed on the inner peripheral surface of the drain pipe connection portion D2. A cylindrical gasket P3 is provided at the end of the stepped portion D2D.

[0054] The second hose connecting portion H2B includes, for example, a connecting cap H6 provided at the end of the hose H. The inner peripheral surface of the connecting cap H6 is formed with engaging portions H6K, the same number as the claw portions H4T protruding radially inward. The engaging portions H6K are formed to engage with the claw portions H4T when the connecting cap H6 is rotated, thereby connecting the first hose connecting portion H2A and the second hose connecting portion H2B. A disk-shaped base H7 is provided at the end of the hose H. The outer diameter of the base H7 is formed to be the same as the outer diameter of the annulus H4, for example.

[0055] An end of the ring H4 abuts against the base H7 when the hose H is connected. The base H7 is provided with a connector C2 that engages with the connector C1, for example. The connector C2 is formed to protrude from the base H7. The connector C2 is provided on the inside with the same number of electrical contacts E2 as the electrical contacts E1 that come into contact with and are electrically connected to the plurality of electrical contacts E1. The connector C2 engages with the connector C1 when the hose H is connected, bringing the electrical contacts E2 into contact with the electrical contacts E1 for electrical connection.

[0056] The base H7 is provided with a water supply pipe connection Q2 that is connected to the water supply pipe connection Q1. In this embodiment, two water supply pipe connection portions Q2 are provided. The water supply pipe connection portions Q2 are formed in a circular pipe shape and protrude from the base H7. When the hose H is connected, the end of the water supply pipe connection portion Q2 presses against the packing P1 provided at the step portion Q1D, causing it to elastically deform, thereby ensuring airtightness between the water supply pipe connection portions Q1 and Q2.

[0057] The base H7 is provided with an air supply pipe connection A4 that is connected to the air supply pipe connection A3. In this embodiment, one air supply pipe connection A4 is provided. The air supply pipe connection A4 is formed in a circular pipe shape and protrudes from the base H7. When the hose H is connected, the end of the air supply pipe connection A4 presses against a packing P2 provided on the step portion A3D, causing it to elastically deform, thereby ensuring airtightness between the air supply pipe connection A3 and the air supply pipe connection A4.

[0058] The base H7 is provided with a drain pipe connection part D3 that is connected to the drain pipe connection part D2. The drain pipe connection part D3 is formed in a circular pipe shape and protrudes from the base H7. When the hose H is connected, the end of the drain pipe connection part D3 presses against the packing P3 provided on the step part D2D, causing it to elastically deform, thereby ensuring airtightness between the drain pipe connection part D2 and the drain pipe connection part D3.

[0059] With the above configuration, when connecting the housing 20B and the hose H, the hose connection portion H2 abuts the first hose connection portion H2A and the second hose connection portion H2B, and then rotates the connection cap H6 to engage the claw portion H4T with the engagement portion H6K, thereby simultaneously connecting the connectors C1 and C2, the water supply pipe connection portion Q1 and Q2, the air supply pipe connection portion A3 and A4, and the drain pipe connection portion D2 and D3.

[0060] As described above, according to the automatic excretion disposal device 1, the expandable body 10 provided in the cup 2 improves the degree of contact between the body of the care recipient and the cup 2, and reliably prevents leakage during disposal of excrement. According to the automatic excretion disposal device 1, the bag body 11 of the expandable body 10 is flexible when expanded and deforms according to the physical condition of the care recipient, reliably reducing the gap between the body and the cup 2. According to the automatic excretion disposal device 1, the expandable body 10 expands during excretion disposal and is normally deflated, thereby preventing strain on the body of the care recipient.

[0061] As described above, the automatic excretion disposal device 1 can reliably prevent leakage of excrement by providing the first bottom 6E and second bottom 6F on the cup 2. According to the automatic excretion disposal device 1, the first bottom 6E comes into contact with the installation surface when the body is in a first supine position, thereby stably fixing the device to the body. According to the automatic excretion disposal device 1, the second bottom 6F comes into contact with the installation surface when the body is in a second semi-sitting position, thereby stably fixing the device to the body and preventing deformation due to bending of the first container 6A and the second container 6B, thereby reliably preventing leakage of excrement.

[0062] According to the automatic excretion disposal device 1, the second container 6B is provided with an inclined surface 10B, which elastically deforms to conform to the shape of the buttocks of the body and adheres closely to it, preventing leakage of excrement. According to the automatic excretion disposal device 1, the expansion body 10 that expands the inclined surface 10B is provided, which elastically deforms to adhere closely to the body when expanded, reliably preventing leakage of excrement.

[0063] According to the automatic excretion disposal device 1, the hose connection part H2 is provided, which simplifies the connection between the hose H and the main body device 20. According to the automatic excretion disposal device 1, the flow path within the hose H is used as a flow path for air supplied from the air supply pipes A1, A2, which reduces the amount of piping within the hose H and simplifies the configuration.

[0064] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the present invention. For example, the working fluid supplied to the expansion body 10 may be flushing water supplied from the flushing device 24. In this case, a separate water supply pipe from the flushing device 24 may be connected to the cup body 6 in addition to the water supply pipe Q, or an expansion water supply pipe branching off from the water supply pipe Q may be connected to the cup body 6.
