Description

Shower-equipped toilet seat device for ostomates

[0001] The present invention relates to a toilet seat device for patients (hereinafter referred to as "ostomates") who have had their excretory route for feces and urine altered by the installation of a stoma such as an artificial anus or artificial bladder due to colon cancer, bladder cancer, inflammatory bowel disease, etc., and who have an excretory opening in the abdomen or lower abdomen. More preferably, the present invention relates to a toilet seat device that can be used by both ostomates and able-bodied people.

[0002] To date, various toilet seat devices equipped with toilet showers for able-bodied persons have been proposed and put into practical use, but most of them have a fixed nozzle located behind the toilet seat. In addition to these fixed nozzles, devices equipped with hand showers have also been proposed, such as those shown in Patent Documents 1 to 5.

[0003] However, as described in detail below, nothing has been developed with the aim of enabling ostomates to use a hand shower comfortably while sitting on the toilet seat when cleaning their pouches. In particular, there is no literature that suggests the appropriate position of the base end connector, despite the knowledge that the position of the connector between the base end of the flexible connection, such as a hose to which the hand shower's shower head is connected, and the hot water supply unit (hereinafter referred to as the base end connector) has a significant impact on the usability of the hand shower.

[0004] Patent Documents 1 to 5 disclose toilet seat devices equipped with hand showers. The toilet seat devices shown in Patent Documents 1 to 3 were developed for other uses, not for ostomates to clean their own pouches. These devices are equipped with hand showers for a person sitting on the toilet seat to clean their own private parts, such as the anus, or for a caregiver to clean the private parts and implements of a person requiring care who is seated on the toilet seat. In the devices shown in Patent Documents 1 to 3, when a seated person cleans their private parts, such as the anus, whether they are doing the cleaning themselves or a caregiver is cleaning, they are seated in a seated position so that their anus is positioned within the toilet seat opening. In such cases, a large forward space (space between the seated person's body and the front end of the toilet seat opening) is not required, as is the case when cleaning a pouch. Therefore, the devices were developed without paying particular attention to the location of the base end connector, and the base end connector is located in various positions.

[0005] Next, Patent Documents 4 and 5 disclose toilet seat devices developed for cleaning pouches for ostomates, and equipped with a hand shower for discharging cleaning water to clean pouches, etc. In the toilet seat devices of Patent Documents 4 and 5, the base end connection part is set as far back as possible.

[0006] The toilet seat devices in Patent Documents 4 and 5 merely add a hand shower for ostomates to a toilet seat that can also be used by able-bodied people, and the toilet seat shown is a standard toilet seat for able-bodied people. Therefore, when an ostomate sits down to use the device, it is difficult to create enough forward space between their body and the front edge of the toilet seat opening to allow for pouch flushing. As a result, they must kneel on the floor facing the toilet or stand bent forward to use the device. In this type of forward-facing position, the location of the base connection does not significantly affect the ease of use of the hand shower, and these documents disclose devices with the hand shower located behind the toilet seat.

[0007] However, requiring the ostomate to clean the pouch in the above-mentioned forward-facing position results in an uncomfortable posture for the ostomate and the need for a separate seat. To solve this problem, a toilet seat device has been proposed, as shown in Patent Document 6. The toilet seat described in Patent Document 6 includes a toilet seat opening, a defecation seating section where the ostomate sits with the anus positioned within the toilet seat opening, and an ostomate seating section located behind the defecation seating section and positioned with the anus positioned behind the toilet seat opening. As a result, when the ostomate cleans their own pouch or urinal, they can simply sit on the deeper (more rearward) ostomate seating section, even while sitting on the toilet seat, as shown in Figure 9, and have sufficient forward space. As a result, they can drain the pouch or use the hand shower for cleaning without straining themselves while sitting.

[0008] However, when a user sits on the toilet seat, the hose becomes too long at the base end connector shown in the toilet seat devices of Patent Documents 4 and 5. In particular, when a user sits on the toilet, the base end connector is located behind the user, and if the hose is routed in front of the user from this invisible position, it becomes difficult to handle the hose.

[0009] Therefore, if the base end connection part is positioned as far forward as possible, it will interfere with the calves and other parts of the legs of an ostomate sitting on the ostomate seat that is positioned towards the rear, forcing the ostomate into an unnatural, spread-legged position.As a result, if it becomes difficult to sit on the ostomate seat and the ostomate is forced to sit towards the front, the space in front required for cleaning the pouch will be narrowed.

[0010] Japanese Patent No. 5168578 Japanese Patent Application Laid-Open No. 2010-255366 Japanese Patent Application Laid-Open No. 61-102925 Japanese Patent Application Laid-Open No. 2004-3302 Japanese Patent Application Laid-Open No. 2002-188200 Japanese Patent No. 6404765

[0011] To provide a toilet seat device that enables an ostomate to use a hand shower comfortably and naturally while sitting on the seat part of the toilet seat in a sitting position when cleaning a pouch.

[0012] The present invention solves the above problems by providing a toilet seat device with a shower for ostomates, which has a toilet seat on which the user sits and a handheld shower unit provided near the toilet seat for cleaning the ostomate's pouch, and which is equipped with the following means.

[0013] The shower section includes a flexible connection path having at least a flexible hose, a hot water supply section to which the base end of the flexible connection path is connected, and a shower head to which the tip end of the flexible connection path is connected.

[0014] The toilet seat has a toilet seat opening, a seating area around the toilet seat opening for a healthy person to sit on when defecating, and an ostomate seating area on which the user can sit with their anus positioned behind the toilet seat opening.

[0015] The base end connection portion of the base end of the flexible connection path to the hot water supply portion is located on the side of the toilet seat, and its front-to-back position is located on the ostomate seat and in the area between the rear end of the toilet seat opening and a position one-third of the total length of the toilet seat opening in the front-to-back direction, and is configured so that the pouch can be washed by the shower portion while the user is seated in a sitting position on the ostomate seat.

[0016] When implementing the present invention, the toilet seat can be a wide-front toilet seat in which the toilet seat opening has a narrow portion at the rear and a wide portion at the front, and the wide portion is formed so that its width in the left-right direction is wider than that of the narrow portion.

[0017] The side of the toilet seat may be provided with a unit box having an operating unit, and the base end connection part may be located on the underside of the unit box, in an area within a distance of one-third of the total length of the toilet seat opening in the front-to-rear direction on both the front and rear sides of the rear end of the toilet seat opening. The base end connection part may also be located at a position that intersects with a left-to-right extension line that passes through the rear end of the toilet seat opening.

[0018] Furthermore, the base end connection portion may be located on the bottom surface of the unit box, and a shower holder for detachably holding the shower head may be disposed on the side surface of the unit box.

[0019] When the shower head is engaged with the shower holder, the hose hangs down from both the base end connection portion and the shower holder and folds back in an approximately U-shape without touching the floor, and when the user is seated in the seated position on the ostomate seat and holding the shower head in his or her hand to wash the pouch, the hose can be configured to reach from the side of the user's legs to the front of the user.

[0020] To provide a toilet seat device that enables an ostomate to use a hand shower comfortably and naturally while seated on the seat of the toilet seat when cleaning a pouch.

[0021] In particular, it has been possible to provide a toilet seat device that allows the user to comfortably sit in a seated position on the ostomate seat located behind the toilet seat opening, and that is equipped with a base end connection part that is advantageous for washing the ostomate pouch in front of the user with a hand shower.

[0023] A toilet seat device according to an embodiment of the present invention will be specifically described below with reference to the drawings. The toilet seat 1 according to this embodiment employs the wide-front toilet seat described in Patent Document 6, but the present invention is not limited to this embodiment and can be implemented with various modifications to the toilet seat configuration. <Regarding the toilet seat>

[0024] The toilet seat device of the present invention is a toilet seat device with a shower for ostomates, which includes a toilet seat 1 on which the user sits and a handheld shower unit located nearby for cleaning the ostomate's pouch. First, the toilet seat 1 will be mainly described with reference to Figures 1 to 6. However, Figures 3 to 6 do not depict the shower unit-related components.

[0025] As shown in Figure 2, the toilet seat 1 has a ring-shaped seat surface 11. In this example, the toilet seat opening 12 of the toilet seat 1 is formed so that the opening width is wider at the front than at the rear in order to ensure a larger working space when the ostomate discharges the contents of the pouch into the toilet bowl while sitting on the toilet seat, but the opening width at the front and rear may be approximately the same.

[0026] More specifically, the toilet seat opening 12 has a front opening width wider than that of a normal toilet seat, and at the rear, the inner peripheral edge of the toilet seat 1 protrudes from the seat surface 11 toward the inside of the opening to form a protruding portion 13, making the rear opening width narrower than the front opening width.

[0027] The protruding portion 13 is formed integrally with the seat surface 11 so that a portion of the inner peripheral edge of the toilet seat 1 bulges into the toilet seat opening 12. As shown in Figure 2, the protruding portion 13 begins to bulge rearward from the front end of the toilet seat opening 12 at the inner peripheral edge of the seat surface 11 at a point corresponding to 1 / 3 to 1 / 2 of the vertical diameter of the opening, and then extends rearward while increasing its protruding width into the toilet seat opening 12, forming a region where the opening width is narrowed. Behind this narrowed region, the opposing protruding portions 13 extend approximately parallel from the left and right, forming a region where the opening width is approximately the same. After passing this approximately uniform region, the protruding width decreases as the protruding portion 13 draws an arc as it approaches the seat surface 11, and finally converges onto the seat surface 11 near the rear end of the toilet seat opening 12.

[0028] The protruding width of the protruding portion 13 from the seat surface 11 is arbitrary, but the width W of the most protruding part is preferably in the range of 30 mm to 50 mm. Note that the term "width" here refers solely to the length in the width direction of the seat surface 11 and the upper surface 131 in a plan view, without taking into consideration the inclination or unevenness of the seat surface 11 and the upper surface 131, which will be described later.

[0029] The protruding portion 13 may be at approximately the same height as the rest of the seat surface, but as shown in Figure 6, in this example cross-sectional shape, the back surface 14, which is the rear side of the seat surface 11, is approximately horizontal, while the seat surface 11 is gently sloped downward toward the inside of the opening. The protruding portion 13 bulging out from the seat surface 11 is formed so that its upper surface 131 slopes downward further toward the inside of the opening than the seat surface 11, and its back surface 133 also slopes downward further toward the inside of the opening than the back surface 14. The thickness of the protruding portion 13 is generally thinner than the seat surface 11 portion. Furthermore, the tip 132 of the protruding portion 13 may be positioned lower than the back surface 14 of the seat surface 11.

[0030] The inclination angle θ1 of the upper surface 131 at the A-A end surface is formed to be larger than the inclination angle θ2 of the seating surface 11. Specifically, the inclination angle θ1 of the upper surface 131 is preferably in the range of 30° to 45°, and the inclination angle θ2 of the seating surface 11 is preferably 10°. Note that the term "inclination angle" used here does not take into consideration the irregularities of the convex surface of the seating surface 11 or the concave surface of the upper surface 131, which will be described later, but simply refers to the inclination angle of an imaginary line connecting the outermost and innermost peripheral sides of the seating surface 11 and the upper surface 131 relative to a horizontal line.

[0031] The upper surface 131 of the protruding portion 13 may be formed as a gently recessed concave surface in cross section, and the seating surface 11 may be formed as a gently rising convex surface in cross section. Furthermore, it is preferable to form the boundary between the upper surface 131 of the protruding portion 13 and the seating surface 11 as a smoothly curved surface, thereby providing continuity between the two.

[0032] The seat surface 11 and the back surface 14 of the toilet seat 1 may be molded as a single unit, or the seat surface 11 and the back surface 14 may be molded separately and their edges may be bonded together using a known welding method such as vibration welding. Note that the bonding method is not limited to this, and other suitable bonding means may be used.

[0033] The toilet seat 1 in this embodiment is rotatably attached to a flushing device 2 provided behind the toilet bowl. A typical flushing device 2 can be used, but for example, as in this embodiment, a flushing device 2 can be used that includes a casing base 21 that is formed in a substantially triangular shape when viewed from the side and an upper casing 22 provided on top of it. This upper casing 22 houses a water supply pipe and the like and is to which the toilet seat 1 and lid are attached, and is disposed on a sloping top surface 211 of the casing base 21. The casing base 21 includes a top surface 221 that is formed substantially parallel to the top surface 211 of the casing base 21, and a protruding portion 222 that further protrudes in a semicircular shape from the top surface 221.

[0034] The cleansing device 2 and the seat 11 are preferably provided with an ostomate seating section 15, which is a substantially flush, continuous surface on which an ostomate can sit. In this example, the ostomate seating section 15 comprises a front seating surface 151 on the seat 11 side and a rear seating surface 152 on the cleansing device 2 side. More specifically, the rear portion of the seat 11 is provided with the front seating surface 151, which is formed to slope upward toward the upper casing 22 as it moves rearward from the rear end of the toilet seat opening 12. This front seating surface 151 is formed to protrude in a gentle arc from the rear edge 111 of the seat toward the toilet seat opening 12, and is formed to be slightly flatter than the rest of the seat 11.

[0035] The rear seating surface 152 on the flushing device 2 side is an inclined surface formed with an upward slope like the front seating surface 151, and this rear seating surface 152 is continuous with the top surface 221 of the upper casing 22. This rear seating surface 152 is formed with approximately the same width as the front seating surface 151, and is formed to protrude toward the rear of the upper casing 22 and reach the protrusion 222. This rear seating surface 152 is formed to be slightly flatter than the other inclined top surface 221. The front seating surface 151 and the rear seating surface 152 form an ostomate seating portion 15, which is a substantially flush, continuous surface. The provision of this ostomate seating portion 15 serves as a guide for the ostomate when sitting behind the toilet seat 1, and allows them to sit stably facing forward on the flush, continuous surface.

[0036] As in this embodiment, a portion of the upper edge of the rear seating surface 152 may be formed to contact the protruding portion 222, and a recess 223 may be formed in part of the front surface of the protruding portion 222 to match the shape of the upper edge of the rear seating surface 152. Such a recess 223 can reduce the discomfort or odd feeling caused by the protruding portion 222 hitting the buttocks when sitting. Note that forming the contour of the ostomate seating portion 15 with curves rather than straight lines, as in this embodiment, is preferable because it gives a softer appearance.

[0037] Furthermore, a recess 17 may be formed by recessing a predetermined area at the boundary between the top surface of the seat surface 11 and the rising inner periphery on the inner periphery near the front end of the toilet seat 1. By providing a recess 17 on part of the inner periphery of the toilet seat 1 in this way, tasks such as urinalysis and catheterization, which are performed in front of the toilet seat opening 12, become easier.

[0038] When a non-handicapped person sits on this toilet seat 1, they sit on the seat surface 11 in a sitting position facing forward, just as when using a normal toilet seat. In this case, if a protruding portion 13 is provided, the person's anus is supported by the protruding portion 13 and the seat surface 11 in its vicinity, with the anus positioned within the toilet seat opening 12. In this example, the protruding portion 13 is formed at a downward incline relative to the seat surface 11, so that the protruding portion 13 rarely comes into direct contact with the buttocks or thighs of a non-handicapped person. This allows non-handicapped people to use the toilet seat without any discomfort.

[0039] In contrast, when an ostomate uses this toilet seat 1, they also sit facing forward, but they differ in that they sit further back than a non-disabled person. When seated on the ostomate seat 15, the ostomate's anus is located further back than the toilet seat opening 12. In this way, the ostomate sits with their weight on the ostomate seat 15 located at the rear, allowing their buttocks to rest stably on the same continuous surface. This prevents their buttocks from shifting while using the toilet, providing a comfortable user experience.

[0040] Furthermore, the toilet seat 1 of this embodiment is formed so that it rises continuously from the rear of the seat surface 11 to the ostomate seating section 15 in a gentle upward motion, allowing the ostomate user to freely choose the front or rear sitting position to suit their own physique. In other words, if the user is short, sitting too far back will prevent their feet from reaching the floor, and they will need to pull their pants or skirt down to their toes in order to spread their legs. Therefore, small-sized ostomates can prevent this problem from occurring by sitting centered on the front seating surface 151 of the ostomate seating section 15. <About the shower section>

[0041] 1 and 7, the shower section comprises a handheld shower head 31 with a shower nozzle at its tip, a flexible connection line 32 whose tip is connected to the shower head 31, and a hot water supply unit box 33 to which the base end of the flexible connection line 32 is connected. The flexible connection line 32 is made up of a flexible hose, but it may also include a water pipe whose base is rotatably connected to the hot water supply unit box 33.

[0042] The unit box 33 is provided with an operating section having operation button switches and a display section on the top surface, and is embodied as a box in which the main part of the hot water supply section is housed, but a part of the hot water supply section may be housed in another location. <Piping system of the hot water supply section>

[0043] Referring primarily to FIG. 7 , the piping system of the hot water supply unit will be described. Water from the mains is supplied from a stop valve 45 to a branch fitting 44. The branch fitting 44 branches water in two directions. One of the branches is connected to a flush tank via a water supply pipe 43 and supplies water for the faucet. The other branch supplies cleaning water from a hose 40 via a solenoid valve 41 and a hose 42 to a tank 38, with an air vent 39 connected just before the tank 38. The tank 38 is equipped with a heater to heat the cleaning water. The cleaning water in the tank 38 is pressurized by an air pump 37 and flows through a flow valve 36 into two flow paths. The first flow path is to a fixed nozzle 35, and the second flow path is to a shower head 31. The flow path to the second shower head 31 is connected from the flow valve 36 to the shower head 31 via an adapter 34 and a flexible connection 32.

[0044] The user operates the operation button on the operation part of the unit box 33 of the hot water supply part. In response to this input, the flow valve 36 switches the flow path, opening either the first flow path to discharge hot water from the fixed nozzle 35, or the second flow path to discharge hot water for pouch washing from the shower head 31. If the operation part of the unit box 33 is equipped with a temperature adjustment button, the heating temperature of the heater in the tank 38 is changed in accordance with this operation. If the operation part is equipped with a discharge strength adjustment button, the output pressure of the air pump 37 is changed in accordance with this operation. The fixed nozzle 35 includes an anal wash and bidet function similar to that of a typical shower toilet, and includes one that can be slightly moved to adjust the washing position, etc. <Proximal end connection part>

[0045] The unit box 33 of the hot water supply section has, at its bottom, a base end connector 30 to which the base end of the flexible connection path 32 is connected. In other words, the base end of the flexible connection path 32 is connected to the underside of the base end connector 30, but it may also be connected to another part such as the side surface or front surface.

[0046] The present invention was completed based on the finding that the position of the base end connector 30 is extremely important for achieving good operability and usability when an ostomate cleans a pouch while seated on the seat of a toilet seat. That is, the present invention was completed based on the finding that there is a close relationship between the position of the base end connector 30 and the position of the anus of a user seated facing forward in terms of achieving good operability and usability.

[0047] When a user sits on the seat during defecation, the position of the user's anus is within the toilet seat opening 12, but when the user sits on the ostomate seat, the position of the user's anus is behind the toilet seat opening 12. For a user sitting facing forward in this relatively rearward position, if the base end connection part 30 is located behind (behind the user's back), it would be difficult to handle the flexible connection path 32 when holding the shower head 31 to clean the pouch. In addition, the path of the flexible connection path 32 would be longer than necessary. Therefore, it is preferable that the base end connection part 30 be located forward of the ostomate seat (more preferably, the position of the user's anus) in the front-to-rear direction.

[0048] On the other hand, being able to spread the legs of a user in a seated position in a V-shape (approximately 90 degrees or more) is advantageous in that it allows for a larger space for pouch cleaning. Although the thickness and length of a user's thighs vary depending on the individual user, when the user spreads their legs approximately 90 degrees around the position of the anus, the thighs will protrude laterally from the outer periphery of the seat surface 11 approximately 10 cm forward. Here, since the front-to-back length of the toilet seat opening 12 is generally approximately 30 cm, if the user's anus is located above the rear end of the toilet seat opening 12, the thighs will protrude laterally from the outer periphery of the seat surface 11 approximately 10 cm forward from the rear end of the toilet seat opening 12 (approximately one-third of the total length of the toilet seat opening 12). Therefore, if the base end connecting portion 30 were located further forward than this, the user's legs would interfere with the unit box 33 or the flexible connecting path 32 would become entangled around the user's legs, making it difficult for the user to assume a spread-legged position.

[0049] Therefore, by positioning the base end connection part 30 in the front-to-back direction in the area Z1 above the ostomate seating part 15 and between the ostomate seating part 15 and a position one-third of the way forward and backward from the toilet seat opening 12, it is possible to avoid interference between the flexible connection path 32 and the unit box 33 and the user's legs, while realizing good handling of hoses, etc.

[0050] More preferably, the base end connection part 30 is disposed in an area Z2 that is within a distance of one-sixth of the front-to-rear length of the toilet seat opening 12 in both the front-to-rear directions from the rear end (i.e., the rearmost part) of the toilet seat opening 12, and even more preferably, the base end connection part 30 is disposed at a position that intersects with a left-to-right extension line L that passes through the rear end (i.e., the rearmost part) of the rear end of the toilet seat opening 12. Here, the base end connection part 30 has an outer diameter that is equal to or slightly larger than the outer diameter of the flexible connection path 32, and it is sufficient if at least a portion of it intersects with the left-to-right extension line L.

[0051] In the illustrated embodiment, as shown in Fig. 1, a shower holder 47 for detachably holding the shower head 31 is attached to the side surface of the unit box 33. With the shower head 31 held in the shower holder 47, the hose of the flexible connection path 32 hangs down from both ends, as shown in Fig. 1, and is held compactly below the unit box 33 in a roughly U-shaped, suspended state without touching the floor on which the toilet is installed. This prevents the hose from becoming tangled around the user's legs or other dangerous situations. Furthermore, when the user is seated on the ostomate seat 15, the shower head 31 is held on the side, making it easy to hold. Furthermore, when the shower head 31 is brought in front of the user's torso to clean the pouch, the hose of the flexible connection path 32 naturally wraps around from the side of the user's leg to the front, making it easy to handle, and the length of the hose from the base end connection part 30 to the shower head 31 can be short, making it possible to hold the pouch in the suspended state described above.

[0052] It is preferable to use a shower head 31 that has a water stop function. Specifically, it is preferable to use a shower head 31 that has a water stop valve inside that allows water to be discharged from the nozzle only when water pressure equal to or greater than a set pressure is applied to the shower head 31, and that does not allow low-pressure residual water to leak out of the nozzle after use. If such a water stop function is not provided in the shower head 31, there is a risk that residual water will drip from the nozzle. Therefore, although not shown in the figure, it is preferable to provide a leak receiver in the shower holder 47 or the like to receive this water and add a drainage path that returns the leaked water to the toilet bowl and drains it away.

[0053] In this embodiment, a wide-front toilet seat with a clearly defined ostomate seating area 102 is used, but the present invention can also be applied to toilet seats that are similar in shape to those for able-bodied people, as long as the user can sit with their anus positioned behind the toilet seat opening 12.
