[0042] Hereinafter, embodiments of the automatic excretion treatment device of the present invention will be described with reference to the accompanying drawings. The automatic excretion treatment device automatically performs excretion treatment for those requiring care.

[0043] like Figure 1 As shown, the automatic excretion treatment device 1 includes a cup 2 (for the automatic excretion treatment device) installed on the body of the person requiring care and a main body device 20 for cleaning the inside of the cup. The automatic excretion treatment device 1 is constructed according to the automatic excretion treatment device described in Patent Document 1. The automatic excretion treatment device 1 is not limited to this and may have other device structures.

[0044] The main device 20 includes: a cleaning device 24 that supplies water from the water supply to clean the inside of the cup 2 and the body of the person being cared for; a drainage device 26 that discharges wastewater containing cleaning water and excrement from the cup 2 into the drain pipe; an air supply device 28 that allows air to circulate inside the cup 2; and a control device 22 that controls the operation of each device.

[0045] The cup 2 has a detection part 3 for detecting excrement, a cup body 6 installed around the crotch of the person requiring care, and an expansion body 10 disposed between the cup body 6 and the body of the person requiring care.

[0046] The control device 22 is electrically connected to the detection unit 3, which will be described later, located 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 drain, clean, and dry the inside of the cup 2.

[0047] The control device 22 integrates and controls the cleaning device 24, the drainage device 26, and the air supply device 28 to perform a cycle of waste disposal. The control device 22 is implemented by a processor such as a CPU (Central Processing Unit) executing programs (software). Some or all of these functional units can be implemented using hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), or FPGA (Field-Programmable Gate Array), or through a combination of software and hardware.

[0048] The cleaning device 24 is connected to the cup body 6 via a water supply pipe Q. The cleaning device 24 is controlled based on a detection value and supplies cleaning water supplied from the upper water supply channel into the cup 2 via the water supply pipe Q. The cleaning device 24 supplies the cup 2 with a set amount of cleaning water based on the detection value.

[0049] The drainage device 26 is connected to the cup body 6 via the drain pipe D. The drainage device 26 is controlled based on the detection value, and draws cleaning water and excrement from the inside of the cup 2 through the drain pipe D and discharges them to the outside of the cup 2, and then discharges the cleaning water and excrement into the sewer.

[0050] An air supply device 28 is connected to the cup body 6 via an air supply pipe A1. The air supply device 28 is controlled based on a detection value, supplying air to the inside of the cup body 6 during excretion treatment. After excrement is discharged from the cup 2 and washed, the air supply device 28 supplies air to the inside of the cup 2 via the air supply pipe A1 to dry the inside of the cup 2 and the body of the person requiring care. Additionally, the air supply device 28 is connected to the expansion body 10 via an air supply pipe A2. The air supply device 28 is controlled based on a detection value, supplying air to the inside of the expansion body 10. The air supply pipe A2 can branch off from the air supply pipe A1 inside the cup 2. A valve (not shown) can be provided between the air supply pipe A1 and the air supply pipe A2. The valve can be, 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 can also be a proportional solenoid valve whose opening and closing amount can be arbitrarily adjusted.

[0051] According to the above structure, excrement is temporarily collected inside cup 2, and cleaning water is supplied from the sewer through cleaning device 24 to clean the body of the person requiring care and the inside of cup 2. The cleaning water and excrement are discharged into the sewer through drainage device 26. After cleaning, air is supplied to cup 2 by air supply device 28 to dry the body of the person requiring care and the inside of cup 2.

[0052] The cup 2 is installed on the body of the person requiring care and has a cup body 6 for receiving excrement. Inside the cup body 6, for example, is a detection unit 3 for detecting excrement. The detection unit 3 is an electrostatic capacitive sensor that electrically detects whether the excrement is solid or liquid. The detection value from the detection unit 3 is output to the control device 22. Based on the detection result from the detection unit 3, the excrement processing cycle of the automatic excrement processing device 1 begins.

[0053] An inflator 10 is disposed between the cup body 6 and the body of the person requiring care. The inflator 10 is controlled based on a detection value. When excrement is detected inside the cup body 6, the inflator 10 is supplied with working fluid and expands to seal against the body of the person requiring care. The working fluid is, for example, air supplied by the air supply device 28. Through the inflator 10, the gap between the body of the person requiring care and the cup 2 is eliminated during excrement disposal, significantly reducing excrement leakage.

[0054] Next, the specific shape of cup 2 will be described. In the following description, the up and down direction of cup 2 is defined with the patient being in a lying position when wearing the cup.

[0055] like Figure 2 and Figure 3 As shown, the cup 2 has a cup body 6 that bulges outward to cover the groin and anus of the person requiring care, and has an internal space. The cup body 6 includes, for example, a first container 6A formed to cover the anus of the person requiring care, a second container 6B formed to cover the groin area of ​​the person requiring care, and a third container 6C connected to the first container 6A and the second container 6B and formed to cover the groin area of ​​the person requiring care. The cup body 6 is integrally formed, for example, from resin.

[0056] The cup body 6 is configured to catch excrement and discharge the cleaning water and excrement supplied from the cleaning device to the outside. Elastic members 6D with curved cross-sections are formed extending from the continuous edges of the first container 6A, the second container 6B, and the third container 6C. The elastic members 6D are, for example, formed of silicone rubber. The elastic members 6D elastically deform upon contact with the body, reducing the gaps between the edges of the first container 6A, the second container 6B, and the third container 6C and the body.

[0057] The first container 6A bulges downwards and bends upwards at its connection with the third container 6C. A detection section 3 is provided inside the first container 6A, for example. A pad 5 supporting the buttocks of the person requiring care is provided around the first container 6A. The pad 5 is plate-shaped. The pad 5 is formed from an elastic material such as sponge rubber with a waterproof sheet covering its surface. The pad 5 is appropriately sized, wider than the buttocks. The pad 5 has a notch for receiving the first container 6A. The pad 5 is detachably attached to the first container 6A. The pad 5 can be removed from the first container 6A and properly cleaned.

[0058] The pad 5 is provided with a wearing fastening member 7 that wraps from the bottom surface of the pad 5 to the abdomen of the person requiring care. The wearing fastening member 7 is formed in the shape of a band. At both ends of the wearing fastening member 7 are fastening parts 7A and 7B that fasten the two ends to each other. The fastening parts 7A and 7B are formed, for example, by Velcro.

[0059] The third container 6C is formed by bulging out vertically and covering the groin area. The third container 6C is provided with a connection part Q1 for the water supply pipe Q, a connection part D1 for the drain pipe D, a connection part A3 for the air supply pipe A1, and a connection part 3C for the detection part 3. Through holes communicating with the internal space of the third container 6C are formed in the connection part A3, the connection part Q1, and the connection part D1.

[0060] The second container 6B bulges upward and bends downward at the connection with the third container 6C. An airflow path 6B1, communicating with the airflow path inside the connection A3, is formed on the outside of the second container 6B. The airflow path 6B1 extends from the connection between the second container 6B and the third container 6C to the front end of the second container 6B. The airflow path 6B1 is closed at the front end of the second container 6B. Multiple air nozzles (not shown) communicating with the inside of the second container 6B are formed along the middle of the airflow path 6B1. When air is supplied from the air supply pipe A1 while it is connected to the connection A3, air flows through the airflow path 6B1, supplying air into the interior of the second container 6B from the multiple nozzles. A plate-shaped cover 8 is provided around the second container 6B.

[0061] The cover 8 is formed in a flat plate shape around the second container 6B, and is formed by bending downward at the connection between the second container 6B and the third container 6C. The cover 8 covers a designated area around the second container 6B when it is installed in the position of the person requiring care, reducing leakage of cleaning water and excrement from around the second container 6B. The cover 8 is formed of an elastic component, such as silicone, to conform to the shape of the person requiring care. An expandable element 10 is provided on the lower surface side of the cover 8, allowing it to expand freely.

[0062] The expandable body 10 comprises a bag 11 that expands upon the inflow of working fluid and a contact layer 9 that comes into contact with the body of the person being cared for. The contact layer 9 is formed of a substantially similar shape to the cover 8 using the same elastic component. That is, the bag 11 is sandwiched between the cover 8 and the contact layer 9. The lower surface of the contact layer 9, for example, exhibits a specified adhesiveness when worn on the human body surface using silicone resin, and has an adhesive force that allows it to detach without causing strain on the human body surface upon removal. The contact layer 9 improves the seal between the cup 2 and the body of the person being cared for. The expandable body 10 may also be formed from the cover 8 and the contact layer 9. That is, the expandable body 10 may also be integrally formed with the cover 8.

[0063] An adhesive layer can be provided between the expansion body 10 and the body to bond the expansion body to the body. That is, an adhesive layer with adhesive strength stronger than that of silicone resin can be formed on the lower surface side of the contact layer 9. The adhesive layer can, for example, have adhesive strength similar to that of adhesive tape. The adhesive layer can be made of double-sided tape or the like.

[0064] like Figure 4 As shown, the bag body 11 is formed in a sheet-like state when not inflated. The upper surface of the bag body 11 is adhered to the lower surface of the cover 8. The lower surface of the bag body 11 is adhered to the upper surface of the contact layer 9. A notch 12 for receiving the second container 6B is formed in the center of the bag body 11. The bag body 11 is formed, for example, from a sheet 13 of a pair of thermoplastic resins such as polyethylene.

[0065] The bag body 11 is formed from a pair of sheets 13 on the upper and lower surfaces. A welded portion 13A of a predetermined width is formed at the outer edges of the two sheets 13 by welding. An unwelded flow path R is formed on a portion of the outer edges of the two sheets 13. A valve portion 13B for supplying working fluid is continuously formed in the flow path R. The valve portion 13B is connected, for example, to an air supply pipe A2, supplying air as the working fluid. According to the above structure, an expansion chamber is formed inside the bag body 11.

[0066] like Figure 5 As shown, the bag 11 is sheet-like when not inflated. Figure 6 As shown, the bag 11 is configured to expand when supplied with working fluid during discharge treatment.

[0067] According to the above structure, for cup 2, when in the body of the person requiring care, air is supplied from air supply device 28 to inflatable body 10 via air supply pipe A2 during excretion, causing bag body 11 to inflate. The inflated bag body 11 presses the contact layer 9 against the body of the person requiring care. The inflated bag body 11 is flexible and deforms according to the state of the body of the person requiring care, thus ensuring that the contact layer 9 fits tightly against the body of the person requiring care without gaps.

[0068] With the inflatable body 10 inflated, excrement is processed inside the cup body 6, preventing cleaning water, excrement, and even odors from inside the cup body 6 from leaking to the outside. Furthermore, during excretion processing, as excrement is drawn from inside the cup body 6 to the drain pipe D, the inflatable body 10 further expands due to the negative pressure generated inside the cup body 6. This further improves the seal between the inflatable body 10 and the body of the person being cared for, preventing gaps from forming. Since the inflatable body 10 also elastically deforms to follow the shape of the body of the person being cared for during expansion, even if the posture of the person being cared for changes, gaps between the cup body 6 and the body of the person being cared for due to the expansion of the inflatable body 10 can be prevented. The bag body 11 or the air supply pipe A2 may be equipped with a regulator to adjust the pressure of the air supplied from the air supply device 28.

[0069] After the excretion process is completed and the air supply device 28 stops operating, air flows back out in the air supply pipe A2, and the expansion body 10 collapses. That is, the expansion body 10 is configured to expand during the excretion process, thereby reducing the burden on the body of the person requiring care.

[0070] The above embodiment shows an example where the expansion body 10 is provided on the cover portion 8, but the expansion body 10 can also be provided on the buttock side of the body of the person requiring care. That is, the expansion body 10 can also be provided on the upper surface side of the pad portion 5.

[0071] The working fluid supplied to the bag body 11 can also be cleaning water supplied from the cleaning device 24. In this case, in addition to the water supply pipe Q, the cup body 6 can be connected to other water supply pipes from the cleaning device 24, and an expansion water supply pipe branching from the water supply pipe Q can also be connected to the cup body 6. A solenoid valve or the like can be installed between the water supply pipe Q and the expansion water supply pipe, and the supply amount of cleaning water to the bag body 11 can be adjusted by the control device 22. The bag body 11 can be provided with a nozzle that sprays cleaning water from the bag body 11 into the interior of the cup body 6. The nozzle maintains the water pressure inside the bag body 11 within a specified range and is formed by an orifice of the diameter that can spray cleaning water and a regulator.

[0072] [Variation Example 1]

[0073] like Figure 7As shown, the expander 10 may have multiple expansion chambers 13R divided according to the position in contact with the body. The multiple expansion chambers 13R are separated by partitions 13C formed by welding. A pressure sensor 13S for detecting internal pressure is provided in each expansion chamber 13R. Each expansion chamber 13R is independently connected to an air supply pipe A4. The multiple air supply pipes A4 are independently supplied from an air supply device 28. The air supply device 28 is controlled by a control device 22. The multiple air supply pipes A4 may also branch from an air supply pipe A1. In this case, multiple valves (not shown) may be provided between the multiple air supply pipes A4 and the air supply pipe A1. Each valve may be, for example, a solenoid valve whose opening and closing is controlled by the control device 22 to adjust the air supply amount. Each valve may also be a proportional solenoid valve whose opening and closing amount can be arbitrarily adjusted.

[0074] The control device 22 independently adjusts the expansion degree of multiple expansion chambers by controlling the air supply device 28 based on the detection value of the pressure sensor 13S. According to the above structure, the control device 22 can independently adjust the expansion degree of the multiple expansion chambers 13R according to the physical condition of the person being cared for. That is, the control device 22 can independently adjust the expansion degree of the multiple expansion chambers 13R based on the detection value of the pressure sensor 13S in a manner that does not place excessive strain on any part of the person being cared for. Furthermore, even if the tightness of the expansion body 10 changes due to the physical activity of the person being cared for during excretion, the control device 22 can still independently adjust the expansion degree of the multiple expansion chambers 13R based on the detection value of the pressure sensor 13S to maintain the tightness of the expansion body 10 with the body and reliably prevent leakage during excretion.

[0075] [Variation Example 2]

[0076] The shape of the cup body 6 is formed in a way that shortens the time required for excretion treatment, and leakage from the cup body 6 can also be effectively prevented.

[0077] like Figure 8 As shown, an anti-adhesion layer S with multiple pit-shaped protrusions S1, formed by embossing, is formed on the inner wall of the first container 6A of the cup body 6. The anti-adhesion layer S can be formed not only on the first container 6A, but also on the inner walls of the second container 6B and the third container 6C.

[0078] like Figure 9 As shown, by forming an anti-adhesion layer S, the gap between the solid and semi-solid excrement X (the object to be treated) and the inner wall of the first container 6A is increased, preventing the excrement X from adhering to the inner wall of the first container 6A. By forming the anti-adhesion layer S, cleaning water and air can easily flow between the excrement X and the inner wall of the first container 6A, promoting the peeling of the excrement from the inner wall of the first container 6A, and allowing the excrement to be easily discharged outside the cup body 6.

[0079] By making it easier for excrement to be discharged outside the cup body 6, the time required for excrement treatment can be shortened, thereby reducing the probability of leakage of treated water and excrement from the cup body 6. In addition to embossing, the anti-adhesion layer S can also be formed by embossing with concave pits, or by forming a layer of anti-adhesion chemicals such as fluoropolymer processing.

[0080] As described above, according to the automatic excretion processing device 1, the cup 2 is provided with an inflatable body 10, thereby improving the seal between the person being cared for and the cup 2 and reliably preventing leakage during excrement processing. According to the automatic excretion processing device 1, the bag 11 of the inflatable body 10 is flexible when inflated, deforming according to the state of the person being cared for, reliably reducing the gap between the body and the cup 2. According to the automatic excretion processing device 1, the inflatable body 10 expands during excretion processing and contracts under normal conditions, thus preventing strain on the person being cared for.

[0081] The above describes embodiments of the present invention, but the present invention is not limited to the above embodiments, and appropriate modifications can be made without departing from its spirit. For example, the expansion body 10 can be formed as a diaper type that can be integrated with or separated from the cup body 6, or it can be configured to further improve the fit. When the expansion body 10 is provided with multiple expansion chambers 13R, the control device 22 can perform machine learning using deep learning based on the detection values ​​of the pressure sensor 13S, and independently optimize and adjust the expansion degree of the multiple expansion chambers 13R according to the physical condition of the person requiring care. Alternatively, in hospitals, nursing facilities, etc., the detection values ​​of the pressure sensor 13S can be aggregated from multiple people requiring care to a server, and the control device 22 can perform machine learning using deep learning based on the aggregated data.
