JP7745936B2 - Cup for automatic excretion treatment device and automatic excretion treatment device - Google Patents

Description

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.

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 in need of care with excretion and reduce the burden on caregivers.

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 cleansing 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.

Patent No. 6635456 JP 2017-153950 A

People requiring care spend their days in a variety of positions, including lying down, tossing and turning, and tilting the bed to raise their upper body. When a person requiring care is in one of these positions, a gap may form between the cup that collects waste and the person's body, potentially resulting in leakage of waste and odors during waste disposal. According to the technology described in Patent Document 1, leakage prevention during waste disposal is achieved by configuring the device to allow air to be sucked in through the gap even if a gap forms between the cup and the body. Through extensive research, the inventors have made further improvements to more reliably prevent leakage during waste disposal.

The present invention aims 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 the person requiring care changes during excretion disposal.

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. The cup comprises a cup body that is attached to the body of the person requiring care and receives excreta; and an expansion body that is provided in the cup body and expands when a working fluid is supplied thereto, thereby coming into close contact with a part of the body that comes into contact with the cup body. The cup body is formed with a first bottom that is formed to contact the installation surface when the person 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 person is in a semi-sitting position.

According to the present invention, the first bottom portion contacts the installation surface when the body is in a first supine position, thereby stably securing the device to the body, and the second bottom portion contacts the installation surface when the body is in a second semi-sitting position, thereby stably securing the device to the body, thereby reliably preventing leakage of excrement.

The present invention makes it possible to reduce leakage during excretion treatment using an automatic excretion treatment device.

Hereinafter, an embodiment of the automatic excretion disposal device according to the present invention will be described with reference to the drawings. The automatic excretion disposal device automatically disposes of excretion for a person requiring care.

As shown in Figures 1 and 2, the automatic excretion disposal device 1 comprises a cup 2 (automatic excretion disposal device cup) 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.

The main device 20 comprises 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.

The cup 2 comprises a detection unit 3 that detects excrement, a cup body 6 that is attached around the crotch area of the person requiring care, and an inflatable body 10 that is placed between the cup body 6 and the body of the person requiring care.

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

The control device 22 comprehensively controls the cleaning device 24, drainage device 26, and 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), ASIC (Application Specific Integrated Circuit), or FPGA (Field-Programmable Gate Array), or may be realized by a combination of software and hardware.

The cleaning device 24 is connected to the cup body 6 via 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 the water supply to the inside of the cup 2 via the water supply pipe Q. A water supply pipe 24A, which supplies clean water from the water supply, is connected to the cleaning device 24. The cleaning device 24 is equipped with, 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 equipped 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 freely adjust the amount of clean water supplied.

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

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

The drainage device 26 sucks sewage from inside the cup 2 through the drain pipe D and drains it outside the cup 2, discharging the sewage 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 is connected downstream of the drainage device 26 for draining sewage into the sewer.

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 individually 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 individually 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.

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

The air supply device 28 is controlled based on the detected value and supplies air to the interior of the inflatable body 10. The air supply pipe A2 may be branched off from the air supply pipe A1 inside the cup 2. 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 can be adjusted as desired.

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

The cup 2 is attached to the body of the person requiring care and comprises 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 unit 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 unit 22. Based on the detection value of the detection unit 3, the control unit 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.

An expandable body 10 is provided between the cup body 6 and the body of the person requiring care. 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 working fluid, expands, and comes into close contact with the body of the person requiring care. The working fluid is, for example, air supplied by the air supply device 28. The expandable body 10 eliminates any gaps between the body of the person requiring care and the cup 2 when disposing of excrement, significantly reducing leakage of excrement.

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 when it is worn by a person requiring care in a lying position.

As shown in Figures 3 to 5, the cup 2 comprises a cup body 6 formed to cover the groin and anal area of the care recipient, a body contact portion 6D that comes into contact with the body of the care recipient, and a hose connection portion H1 that is connected to a hose H. The cup 2 is typically positioned in a first supine position in which the care recipient lies on their back. The cup 2 is attached to the body so that the direction of the tube axis L of the hose connection portion H1 is approximately aligned with the left-right central axis of the body in a plan view.

The cup body 6 is configured 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 person requiring care, and a second container 6B that is placed on a mounting surface and covers the groin and anal area of the person requiring care. The first container 6A and the second container 6B are formed, for example, from resin.

The first container 6A bulges outward, forming an internal space. A protrusion 6T protruding outward is formed on the outer wall 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. The flow path has at least one through hole 6W formed in it that communicates with the inner wall of the first container 6A. The cleaning water and air circulating through 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 within a hose H.

A detection unit 3 (see Figure 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.

The second container 6B is positioned 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 6E formed to contact the installation surface and a second bottom 6F formed continuously with the first bottom 6E at a dihedral angle θ. The first bottom 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 person requiring care assumes a second semi-sitting position in which the lower half of the body is inverted against the bed and the upper half is raised. The second bottom 6F is formed to contact the installation surface when the body is in the second semi-sitting position.

An embossed anti-adhesion layer S having multiple 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 (material to be treated) 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 cleaning 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 making it easier to discharge the waste outside the cup body 6.

By making it easier for waste to be discharged outside the cup body 6, the time required for waste treatment can be shortened, thereby reducing the likelihood of treated water or waste leaking from the cup body 6. The anti-adhesion layer S may be formed by embossing, debossing with concave dimples, or by a layer of a chemical substance that prevents adhesion, such as a fluororesin coating.

A body contact portion 6D that comes into contact with the body of the person requiring care is provided around the first container 6A and the second container 6B and extends therefrom. The body contact portion 6D is formed, for example, from an elastic material such as silicone rubber. One side of the first region 6D1 of the body contact portion 6D around the first container 6A faces the external space. An adhesive layer having adhesive properties is formed on the other side of the first region 6D1 facing 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 made of double-sided tape, etc.

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 side of the second region 6D2. An expandable expandable body 10 is provided on the other side of the second region 6D2 facing 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.

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. The hose connection part H1 only needs to be 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 requiring care is in the first or second position, preventing deformation of the cup 2 and preventing excrement from leaking from within the cup 2.

The inclined surface 10B is formed at an 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 portion H1. The inclined surface 10B is formed to contact, for example, the intergluteal cleft of the buttocks of the body. The inclined surface 10B is formed to extend from the intergluteal cleft to match the contact area including the base of the inner thigh.

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, for example, from 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 expanded, 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 expanded, the inclined surface 10B elastically deforms to adhere closely to the body side depending on the degree of expansion of the expandable body 10.

Expandable body 10 begins to expand at the start of the excretion process when detection unit 3 detects excrement, and finishes expanding at the end of the excretion process when excreta in cup 2 is expelled from cup 2 and body drying is complete. Air is supplied to flow path 10S of expandable body 10, and inclined surface 10B deforms to bulge toward the body. When expandable body 10 expands, inclined surface 10B presses against the body, adhering to the body and preventing excrement, cleaning water, etc. from leaking from the internal space of cup 2.

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

When the expandable body 10 is in an expanded state, waste is processed inside the cup body 6, preventing the cleaning water, waste, and even odors from inside the cup body 6 from leaking to the outside. Furthermore, the expandable body 10 expands further due to the negative pressure generated inside the cup body 6 when waste is sucked into the drain pipe D from inside the cup body 6 during waste processing. 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 forming.

When the person requiring care is in the first posture lying on their back, 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 person requiring care. The expandable body 10 expands when excretion processing begins in the first posture of the person requiring care, increasing the degree of contact with the body of the person requiring care compared to when it is not inflated.

When the care recipient is in the second semi-sitting position, 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 body position. The expandable body 10 expands when the care recipient begins excretion processing in the second body position, increasing the degree of contact with the care recipient's body compared to when it is not expanded.

The expandable body 10 elastically deforms to conform to the shape of the body of the care recipient even when inflated, preventing the expansion of the expandable body 10 from creating a gap between the cup body 6 and the body of the care recipient, even if the body posture of the care recipient changes. 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.

After the excretion process is completed and the air supply device 28 stops operating, the expandable body 10 deflates as the air flows back up the air supply pipe A2. In other words, because the expandable body 10 is configured to expand during the excretion process, the physical burden on the care recipient is reduced.

A solenoid valve or the like may be provided between the water supply pipe Q and the expansion water supply pipe, and the amount of flushing 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 for discharging flushing water into the cup body 6. The discharge port may be formed by a regulator or a hole with a diameter that discharges flushing water while maintaining the water pressure inside the expansion body 10 within a predetermined range.

As shown in FIG. 7, the main unit 20 has a box-shaped housing 20B. Internal equipment such as a control device 22 (see FIG. 1) is provided inside the housing 20B. The housing 20B is formed, for example, from a resin material. The housing 20B may also be formed from a metal plate such as an aluminum plate. An operation unit 20C for operating the main unit 20 is provided on the top side of the housing 20B. The operation unit 20C may be composed of a display screen displayed on a separately provided terminal device (not shown) capable of communication.

The front side of the housing 20B is provided with, for example, a hose connection portion H2 for attaching a hose H, a water supply pipe connection portion 24C for connecting a clean water pipe 24A, and a drain pipe connection portion 24D for connecting a drain pipe 24B. The hose connection portion H2 is detachably attached to the housing 20B. When the hose connection portion 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 within 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 portion H2 is separated from the housing 20B.

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 peripheral 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 peripheral 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.

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 portions Q1 are formed in a cylindrical shape and protrude from the base H5. A stepped portion Q1D that is reduced in diameter is formed on the inner surface of the water supply pipe connection portion Q1. A cylindrical gasket P1 is provided at the end of the stepped portion Q1D.

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 tube shape and protrudes from the base H5. A stepped portion A3D that is reduced in diameter is formed on the inner surface of the air supply pipe connection portion A3. A cylindrical gasket P2 is provided at the end of the stepped portion A3D.

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 surface of the drain pipe connection portion D2. A cylindrical gasket P3 is provided at the end of the stepped portion D2D.

The second hose connection portion H2B, for example, comprises a connection cap H6 provided at the end of the hose H. The inner circumferential surface of the connection cap H6 is formed with the same number of engagement portions H6K as the claw portions H4T protruding radially inward. The engagement portions H6K are formed to engage with the claw portions H4T when the connection cap H6 is rotated, connecting the first hose connection portion H2A and the second hose connection 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, for example, to be the same as the outer diameter of the annulus H4.

When the hose H is connected, the end of the ring H4 abuts against the base H7. 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 inside of the connector C2 is provided with the same number of electrical contacts E2 as the electrical contacts E1 that come into contact with and are electrically connected to the multiple electrical contacts E1. When the hose H is connected, the connector C2 engages with the connector C1, bringing the electrical contacts E2 into contact with the electrical contacts E1 to form an electrical connection.

The base H7 is provided with a water supply pipe connection portion Q2 that connects to the water supply pipe connection portion 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 tube 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 gasket P1 provided on the step portion Q1D, causing it to elastically deform, thereby ensuring airtightness between the water supply pipe connection portion Q1 and the water supply pipe connection portion Q2.

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

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

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.

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, reliably preventing leakage during excreta disposal. 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, preventing strain on the body of the care recipient.

As described above, the automatic excretion disposal device 1 has a first bottom 6E and a second bottom 6F on the cup 2, thereby reliably preventing leakage of excrement. The automatic excretion disposal device 1 allows the first bottom 6E to come into contact with the installation surface when the body is in a first supine position, thereby stably securing the device to the body. The automatic excretion disposal device 1 allows the second bottom 6F to come into contact with the installation surface when the body is in a second semi-sitting position, thereby stably securing 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.

The automatic excretion disposal device 1 has an inclined surface 10B on the second container 6B, which allows it to elastically deform to conform to the shape of the buttocks of the body and adhere closely to it, preventing leakage of excrement. The automatic excretion disposal device 1 has an expansion body 10 that expands the inclined surface 10B, which elastically deforms to adhere closely to the body when expanded, reliably preventing leakage of excrement.

The automatic excretion treatment device 1 is provided with a hose connection portion H2, which simplifies the connection between the hose H and the main device 20. The automatic excretion treatment device 1 uses the flow path within the hose H as a flow path for air supplied from the air supply pipes A1 and A2, which reduces the amount of piping within the hose H and simplifies the configuration.

The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the invention. For example, the working fluid supplied to the expansion body 10 may be cleaning water supplied from the cleaning device 24. In this case, a separate water supply pipe from the cleaning 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.
