It is arranged in an area up to one-third of the total length in the front-rear direction.

Description

The present invention is aimed at patients who have changed their fecal or urine excretion route and created an excretory port in their abdomen or lower abdomen by adding a stoma such as an artificial anus or an artificial bladder due to colon cancer, bladder cancer, or inflammatory bowel disease. The present invention relates to a toilet seat device for a person (hereinafter referred to as an "ostomate"). More preferably, the present invention relates to a toilet seat device that can be shared by an ostomate and a healthy person.

To date, various structures have been proposed and put into practical use as toilet seat devices with a toilet shower for healthy people, but most of them have a fixed nozzle placed behind the toilet seat. In addition to these fixed nozzles, those equipped with a hand shower have also been proposed, such as those shown in Patent Documents 1 to 5.

However, as detailed below, the hand shower was developed for the purpose of allowing an ostomate to use the hand shower comfortably while sitting on the seat of the toilet seat when cleaning the pouch. There was nothing. In particular, the position of the connection between the base end of the flexible connection path, such as the hose to which the hand shower head is connected, and the hot water supply section (hereinafter referred to as the base end connection part) has a large effect on the usability of the hand shower. Based on this knowledge, there was no literature that proposed the appropriate position of the proximal connection portion.

Patent Documents 1 to 5 disclose toilet seat devices equipped with a hand shower.
First, the toilet seat devices shown in Patent Documents 1 to 3 were developed not for the purpose of cleaning the pouch by the ostomate themselves, but for other uses. A hand shower is attached to the toilet so that the caregiver can clean the anus and other private parts of the person sitting on the toilet seat, or the caregiver can clean the anus and other private parts of the person sitting on the toilet seat. What is shown in these Patent Documents 1 to 3 is that when a seated person cleans the private parts such as the anus, whether the person himself or a caregiver cleanses, The patient is seated in a sitting position with the anus located within the opening of the toilet seat. In such a case, a large front space (space between the seated person's body and the front end of the toilet seat opening) is not required as much as when cleaning the pouch. Therefore, it was developed without paying particular attention to the position of the proximal end connection part, and the proximal end connection part is set at various positions.

Next, Patent Documents 4 and 5 are developed for cleaning ostomate pouches, and disclose toilet seat devices equipped with a hand shower for discharging cleaning water to clean pouches, etc. in a toilet bowl. There is. In the toilet seat devices of these Patent Documents 4 and 5, the proximal end connection portion is set to be as far back as possible.

These toilet seat devices of Patent Documents 4 and 5 are simply toilet seats used by healthy people with a hand shower used by ostomates added, and the toilet seats are also general toilet seats for healthy people. Therefore, when the ostomate uses the toilet seat while sitting in a sitting position, it becomes difficult to secure sufficient front space between the ostomate's body and the front end of the toilet seat opening necessary for cleaning the pouch. As a result, it was necessary to use the toilet by kneeling on the floor or leaning forward while facing the toilet. In such a facing position, the position of the proximal end connection part does not have a great effect on the usability of the hand shower, and these documents disclose a hand shower that is set behind the toilet seat.

However, requiring the ostomate to wash the pouch in a facing position as described above has resulted in forcing the ostomate into a position that is difficult for the ostomate, or requiring the ostomate to prepare a separate seat. In order to solve this problem, a toilet seat device shown in Patent Document 6 has been proposed. The toilet seat described in Patent Document 6 has a toilet seat opening, a defecation seating part that is seated so that the anus is located within the toilet seat opening, and a defecation seating part that is seated so that the anus is located behind the toilet seat opening. It also has a rear ostomate seating area. As a result, when the ostomate cleans his or her own pouch or urine bottle, even if the ostomate is sitting on the toilet seat, the ostomate only needs to sit on the deeper (backwards) ostomate seating area, as shown in Figure 9. You can get enough space in front. As a result, draining water from pouches and the like and cleaning using a hand shower can be performed comfortably while sitting in a seated position.

However, in the sitting posture of sitting on the toilet seat, the length of the hose becomes too long at the proximal end connection portion shown in the toilet seat devices of Patent Documents 4 and 5. In particular, when the user is in a sitting position, the proximal end connection portion is behind the user, and if the hose is passed in front of the user from a position where the user cannot see it, the hose becomes difficult to manage.

For this reason, if you try to set the proximal end connection part as far forward as possible, it will interfere with the legs such as the calves of the ostomate who is sitting on the ostomate seating part near the rear, forcing the ostomate into an unreasonable leg posture. become. Therefore, if it becomes difficult to sit on the ostomate seating part and the user is forced to sit closer to the front, the front space necessary for cleaning the pouch becomes narrower.

<About the toilet seat>

The toilet seat device of the present invention is a toilet seat device with a shower for an ostomate, which includes a toilet seat 1 on which a user sits down, and a handheld shower section provided near the toilet seat 1 for washing an ostomate pouch. First, the toilet seat 1 will be mainly explained with reference to FIGS. 1 to 6. However, in FIGS. 3 to 6, the structure related to the shower section is not depicted.

As shown in FIG. 2, the toilet seat 1 includes a seat surface 11 formed in an annular shape. In this example, the toilet seat opening 12 of the toilet seat 1 is wider at the front than at the back in order to ensure a wider working space for the ostomate to discharge the contents of the pouch into the toilet bowl while sitting on the toilet seat. However, the front and rear openings may have substantially the same opening width.

More specifically, the toilet seat opening 12 has a front opening width wider than that of a normal toilet seat, and at the rear thereof, the inner peripheral edge portion of the toilet seat 1 protrudes from the seat surface 11 toward the inside of the opening, forming a protruding portion. 13, the rear opening width is narrower than the front opening width.

The protruding portion 13 is formed integrally with the seat surface 11 so that a part of the inner peripheral edge of the toilet seat 1 bulges into the toilet seat opening 12. As shown in FIG. 2, the protruding portion 13 starts expanding backward from the front end of the toilet seat opening 12 from the inner peripheral edge of the seat surface 11, which corresponds to 1/3 to 1/2 of the vertical diameter of the opening, and extends inside the toilet seat opening 12. It extends rearward while bulging out so that the opening width increases, forming a region that narrows the opening width. Further, behind the narrowed region, the protruding portions 13 facing each other from the left and right extend substantially parallel to form a region having substantially the same opening width. After passing through the approximately same area, it approaches the seat surface 11 in an arc while decreasing its protruding width, and finally converges to the seat surface 11 near the rear end of the toilet seat opening 12. .

The protruding width of the protruding portion 13 from the seat surface 11 is arbitrary, but the width W of the most protruding portion is preferably in the range of 30 mm to 50 mm. Note that the term "width" here refers only to the widthwise length of the seat surface 11 and the top surface 131 in a plan view, without considering the slope or uneven surface of the seat surface 11 and the top surface 131, which will be described later.

The protruding portion 13 may be at approximately the same height as the other seat surfaces, but as shown in FIG. In contrast, the seat surface 11 is provided with a gentle downward slope toward the inside of the opening. The protruding portion 13 that bulges out from the seat surface 11 is formed so that its upper surface 131 is inclined further down toward the inside of the opening than the seat surface 11, and its back surface 133 is also inclined further toward the inside of the opening than the back surface 14. It is formed with a downward slope. The thickness of the protruding portion 13 is formed to be thinner overall than the portion of the seat surface 11. Further, the tip end 132 of the protruding portion 13 may be located below the back surface 14 of the seat surface 11.

The inclination angle θ1 of the upper surface 131 at the AA end face is formed to be larger than the inclination angle θ2 of the seat 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 seat surface 11 is preferably 10°. Note that when we say "angle of inclination" here, we do not take into account the unevenness of the convex surface of the seat surface 11 or the concave surface of the upper surface 131, which will be described later, and only refer to the outermost and innermost circumferential sides of the seat surface 11 and the upper surface 131, respectively. It refers to the angle of inclination of the imaginary straight line connecting the lines with respect to the horizontal line.

Further, the upper surface 131 of the protruding portion 13 may be formed in a concave curved shape that is gently concave when viewed in cross section, and the seat surface 11 may be formed in a convex curved shape that is gently raised in cross section. Further, it is preferable that the boundary between the upper surface 131 of the protruding portion 13 and the seat surface 11 be formed into a smooth curved surface to provide continuity therebetween.

The seat 11 and the back surface 14 of the toilet seat 1 may be integrally molded, but the seat surface 11 and the back surface 14 may be molded separately and their edges bonded together using a known welding method such as vibration welding. I don't mind. Note that the bonding method is not limited to this, and other appropriate bonding means can be used.

The toilet seat 1 of this embodiment is rotatably attached to a cleaning device 2 installed at the rear of the toilet bowl. Such a cleaning device 2 can be of a general type, but for example, as in the present embodiment, a casing base 21 having a substantially triangular shape in side view and an upper casing 22 provided above the casing base 21 can be used. A cleaning device 2 equipped with the following can be used. The upper casing 22 houses a water supply pipe and the like, and is attached with the toilet seat 1 and a lid, and is arranged on the inclined top surface 211 of the casing base 21. The casing base 21 includes a top surface portion 221 formed substantially parallel to the top surface portion 211 of the casing base body 21, and a protrusion portion 222 further protruding from the top surface portion 221 in a semicircular shape.

The cleaning device 2 and the seat surface 11 are preferably provided with an ostomate seating portion 15 that is a substantially flush continuous surface on which an ostomate can sit. In this example, the ostomate seating portion 15 includes a front seating surface 151 on the side of the seating surface 11 and a rear seating surface 152 on the cleaning device 2 side. Specifically, the rear portion of the seat surface 11 includes a front seat surface 151 that is sloped upward toward the upper casing 22 as it goes rearward from the rear end of the toilet seat opening 12. The front seating surface 151 is formed to extend in a gentle arc shape from the rear end side 111 of the seat surface toward the toilet seat opening 12 side, and is formed to be slightly flatter than the other portions of the seat surface 11.

The rear seating surface 152 on the cleaning device 2 side is an inclined surface formed in an upward slope like the front seating surface 151, and this rear seating surface 152 is continuous with the top surface portion 221 of the upper casing 22. There is. The rear seating surface 152 is formed to have substantially the same width as the front seating surface 151, extends rearward of the upper casing 22, and is formed to reach the protrusion 222. The rear seating surface 152 is formed to be slightly flatter than the other inclined top surface portion 221. The front seating surface 151 and the rear seating surface 152 form an ostomate seating portion 15 that is a substantially flush continuous surface. By providing the ostomate seating portion 15 in this way, the ostomate can serve as a guide when sitting at the rear of the toilet seat 1, and can stably sit on a continuous flush surface facing forward.

As in the present embodiment, a part of the upper side of the rear seating surface 152 is formed so as to be in contact with the protrusion 222, and the front surface of the protrusion 222 is formed in accordance with the shape of the upper side of the rear seating surface 152. The concave portion 223 may be formed in a part of. Such a recess 223 can suppress the discomfort or discomfort caused by the protrusion 222 hitting the buttocks when the user is seated. Note that it is preferable that the outline of the ostomate seating portion 15 is formed not in a straight line but in a curved line as in the present embodiment, since it can give a soft impression in appearance.

Furthermore, a concave portion 17 may be formed in the inner circumferential edge of the toilet seat 1 near the front end, by recessing the boundary between the top surface of the seat surface 11 and the rising inner circumferential side within a predetermined range. By providing the recessed portion 17 in a part of the inner peripheral edge of the toilet seat 1 in this way, operations such as urine testing and urine catheterization performed in front of the toilet seat opening 12 are made easier.

When an able-bodied person sits on this toilet seat 1, he or she sits on the seat surface 11 in a sitting position facing forward, as in the case of using a normal toilet seat. At this time, if the protruding part 13 is provided, it is supported by the protruding part 13 and the seat surface 11 in the vicinity thereof, and its anus position is within the toilet seat opening 12. In this example, since the protruding part 13 is formed to be inclined downward with respect to the seat surface 11, the protruding part 13 rarely comes into direct contact with the buttocks, thighs, etc. of a healthy person. This allows healthy people to use it without any discomfort.

On the other hand, when the toilet seat 1 is used by an ostomate, the ostomate sits in a seated position facing forward, but the difference is that the ostomate sits further back than an able-bodied person. When the ostomate is seated on the ostomate seating portion 15 in a sitting position, the anus of the ostomate is located behind the toilet seat opening 12. In this way, the ostomate sits with his weight on the ostomate seating section 15 provided at the rear, so that his buttocks are stably placed on the same continuous surface. As a result, a good feeling of use can be obtained without causing the buttocks to shift during work.

Note that the toilet seat 1 of this embodiment is formed continuously so as to be gently raised from the rear of the seat surface 11 to the ostomate seating portion 15, so that the ostomate user can adjust the sitting position forward and backward according to his/her physique. It can be selected arbitrarily. That is, if the user is short, if the user sits too far back, the feet will not reach the floor, and the user will have to pull down the pants or skirt to the feet in order to spread the crotch further. Therefore, if an ostomate with a small build uses the ostomate sitting part 15 while sitting mainly on the front seating surface 151 on the front side, the occurrence of such problems can be suppressed.
<About the shower section>

As shown in FIGS. 1 and 7, the shower section includes a handheld shower head 31 with a shower nozzle at its tip, a flexible connection path 32 whose tip is connected to the shower head 31, and a base of the flexible connection path 32. A unit box 33 of a hot water supply unit is connected at one end. The flexible connection path 32 is composed of a flexible hose, but may also include a water conduit pipe whose base is rotatably connected to the unit box 33 of the hot water supply section.

The unit box 33 is equipped with an operation section having button switches and a display section for operation on the top surface, and is implemented as housing the main part of the hot water supply section, but a part of the hot water supply section is It does not matter if it is stored in another part.
<Piping system of hot water supply section>

The piping system of the hot water supply section will be described with reference mainly to FIG. 7. Water from the tap is supplied from the water stop valve 45 to the branch fitting 44. The branch fitting 44 is for dividing water into two directions, one of which is connected to a flush tank via the water supply pipe 43 to supply faucet water. The other one supplies cleaning water from a hose 40 to a tank 38 via a solenoid valve 41 and a hose 42, and an air vent 39 is connected in front of 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 the air pump 37, passes through the flow valve 36, and flows out into two flow paths. The first flow path is a flow path to the fixed nozzle 35, and the second flow path is a flow path to the 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 path 32.

The user operates the operation button on the operation section of the unit box 33 of the hot water supply section. According to the input, flow path switching is performed to open the first flow path and discharge hot water from the fixed nozzle 35, or open the second flow path and discharge hot water for pouch cleaning from the shower head 31. The flow rate valve 36 performs this. In addition, when the operation part of the unit box 33 is equipped with a temperature adjustment button, the heating temperature of the heater of the tank 38 is changed according to the operation. Further, if a discharge strength adjustment button is provided, the output pressure of the air pump 37 is changed according to the operation of the button. The fixed nozzle 35 includes an anal cleaning and a bidet similar to those in a general shower toilet, and includes a part whose position can be changed slightly to adjust the cleaning position.
<Proximal connection part>

The unit box 33 of the hot water supply section includes a base end connection section 30 at its lower part 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 lower surface of the base end connection portion 30, but the flexible connection path 32 may be connected to other parts such as a side surface or a front surface.

It has been found that the position of the proximal end connection part 30 is extremely important for obtaining good operability and feeling when cleaning the pouch while the ostomate is seated in a seated position on the seat of the toilet seat. , the present invention has been completed. In other words, it has been found that there is a close relationship between the position of the proximal end connection part 30 and the position of the anus of a user who is seated in a forward facing posture in order to obtain good operability and usability. Thus, the present invention was completed.

The user's anus is located within the toilet seat opening 12 when the user sits on the seat during defecation, but the user's anus is located behind the toilet seat opening 12 when the user sits on the ostomate seat. For a user who is sitting in this relatively backward position facing forward, if the proximal end connection part 30 is at the back (behind the back), the user can easily connect the flexible connection when holding the shower head 31 and washing the pouch. This makes it difficult to route the road 32. Moreover, the route of the flexible connection path 32 becomes longer than necessary. Therefore, it is preferable that the base end connecting part 30 be located in front of the ostomate seating part (more preferably, the position of the user's anus) in the front-rear direction.

On the other hand, it is advantageous for the user who is seated in a sitting position to be able to open his/her legs in a V-shape (approximately 90 degrees or more) in that a wide space can be secured for cleaning the pouch. The thickness and length of the user's thighs vary depending on individual differences between users, but if you open your legs approximately 90 degrees around the anus position, your thighs will be approximately 10 cm in front of you. It protrudes laterally from the outer periphery of the seat surface 11. Here, since the front-to-back length of the toilet seat opening 12 is generally about 30 cm, if the position of the user's anus is above the rear end of the toilet seat opening 12, the distance from the rear end of the toilet seat opening 12 to about 10 cm (toilet seat At a position approximately 1/3 forward of the entire length of the opening 12, the thigh protrudes laterally from the outer periphery of the seat surface 11. Therefore, if the proximal connection part 30 is located ahead of this, the user's legs may interfere with the unit box 33 or the flexible connection path 32 may become entangled with the legs, which may prevent the user from holding the open leg posture. It becomes difficult to take.

Therefore, the proximal end connecting portion 30 can be flexible by arranging the proximal end connection portion 30 in the region Z1 above the ostomate seating portion 15 and between the ostomate seating portion 15 and one third of the toilet seat opening 12 in the front and back direction. Good routing of hoses and the like can be achieved while avoiding interference between the connection path 32 and unit box 33 and the user's legs.

More preferably, the proximal end connection portion 30 extends from the rear end (i.e., the rearmost portion) of the toilet seat opening 12 in both the front and rear directions to a region Z2 within a distance of one-sixth of the length of the toilet seat opening 12 in the front and back direction. More preferably, the proximal end connecting portion 30 is disposed at a position intersecting the left-right direction extension line L passing through the rear end (ie, the rearmost portion) of the rear end of the toilet seat opening 12. Here, the proximal end connecting portion 30 has an outer diameter that is equal to or slightly larger than the outer diameter of the flexible connecting path 32, but it is sufficient that at least a portion thereof intersects with the left-right direction extension line L.

In the illustrated embodiment, as shown in FIG. 1, a shower holder 47 that removably locks the shower head 31 is attached to the side surface of the unit box 33. As a result, when the shower head 31 is locked to the shower holder 47, the hoses of the flexible connection path 32 hang down from both ends as shown in FIG. 1, and come into contact with the floor surface on which the toilet is installed. It is folded back into a substantially U-shape and suspended in the air, and is compactly held below the unit box 33. This prevents dangerous situations such as the hose becoming tangled with the user's legs. When the user is seated on the ostomate seating section 15 in a sitting posture, the shower head 31 is held on the side thereof, so that it is easy for the user to hold the shower head 31 in his/her hand. Furthermore, when the shower head 31 is brought to the front of the user's torso in order to clean the pouch, the hose of the flexible connection path 32 naturally wraps around from the side of the user's legs to the front of the user's torso. It is easy to handle, the length of the hose from the base end connection part 30 to the shower head 31 is short, and the above-mentioned suspended state can be achieved.

It is preferable to use a shower head 31 having a water stop function. In detail, the shower head is equipped with a water stop valve that allows water to be discharged from the nozzle only when water pressure higher than the set pressure is applied to the shower head 31, and does not allow low-pressure residual water to leak out from the nozzle after use. It is preferable to use the one provided in 31. If such a water stop function is not provided in the shower head 31, residual water may drip from the nozzle. It is preferable to add a drainage channel to drain the leaked water back to the toilet bowl.

In this embodiment, a wide front toilet seat with a clearly formed ostomate seating part 102 is used, but even if the toilet seat is similar in shape to a toilet seat for a healthy person, the user's anus will not be closer to the toilet seat opening 12. The present invention can be applied to any vehicle that can be seated so that it is located at the rear.
