Description

The present invention is for a patient having an excretion port in the abdomen or lower abdomen by changing the excretion route of stool or urine and adding a stoma such as an artificial anus or an artificial bladder due to colorectal cancer, bladder cancer, inflammatory bowel disease, or the like. Hereinafter, the toilet seat for (referred to as "ostomate"), and more specifically, the toilet seat that can be shared by the ostomate and a healthy person.

Conventionally, when an ostomate uses a Western-style toilet, excretion is performed by opening the mouth of a pouch attached to an abdominal stoma. This work may be done by standing in front of the toilet bowl, bending over and sitting on the waist, or by holding the toilet bowl with knees on the floor. It is preferable to work in a seated state.

When working in a seated state, it is necessary to sit on the back side of the toilet seat so that the opening of the toilet seat can be used as widely as possible. However, in the case of a general type toilet seat, it is extremely difficult to sit on the back side of the toilet seat, and it may be difficult to sit on the toilet seat if there is no depth. In addition, the narrow opening made it inconvenient for ostomates to work.

Therefore, in order to solve such a problem, in Patent Documents 1 and 2, the opening width of the opening of the toilet seat is widened in the front with respect to the rear so that the ostomate can sit stably on the back side when using it. Disclosed is an ostomate-compatible toilet seat that can be used and has a space on the front side for processing so that defecation and urination processing work can be easily performed.

These toilet seats are supposed to be used not only by ostomates but also by healthy people, but when healthy people use them in the same way as normal toilet seats, the following problems have arisen. That is, in the case of these ostomate toilet seats, behind the toilet seat having a narrow opening width, the corners of the inner peripheral edge of the seat surface protrude and hit the ischium or the like depending on the sitting posture, which may cause a feeling of strangeness. ..

However, if the protrusion on the inner edge of the seat surface is removed, the opening width will be uniformly widened not only in the front but also in the rear, causing anxiety and fear that the buttocks may fall into the opening. There is also a feeling of psychological resistance when using it. Therefore, there is a demand for an ostomate-compatible toilet seat that can be used with peace of mind by widening the opening width only in the front like a conventional ostomate toilet seat, and that the feeling of use for healthy people is not different from that of a normal toilet seat. Was.

Therefore, the present invention overcomes the drawbacks of the conventional ostomate and healthy person shared toilet seat, can secure a sufficient work space in front, and is not uncomfortable when used by healthy people. The issue is the provision of toilet seats.

The present invention solves the above-mentioned problems, and is an ostomate and a healthy person shared toilet seat having an opening formed so that the opening width is wider in the front than in the rear, and the inside of the toilet seat is behind the opening. The peripheral portion protrudes from the seat surface to the inside of the opening to form a protruding portion, and the protruding portion narrows the rear opening width with respect to the front opening width, and the upper surface of the protruding portion is formed. It is a toilet seat shared by ostomates and healthy people, which is characterized in that it is formed so as to be inclined toward the inside of the opening more than the other seat surface portions.

Further, in the present invention, the toilet seat is rotatably attached to a cleaning device provided at the rear of the toilet bowl, and a seating surface is formed on the seating surface side so as to be slightly flatter than other seating surface portions. The ostomate and the ostomate are characterized in that a seating surface is formed on the cleaning device side so as to be slightly flatter than the top surface of the casing, and a substantially uniform ostomate seating portion is formed by these seating surfaces. It is a toilet seat with a cleaning function shared by healthy people.

Further, the present invention is a toilet seat with a cleaning function shared by ostomates and healthy persons, characterized in that a recessed portion is provided in which the boundary portion between the top surface of the seat surface and the rising surface on the inner peripheral side is recessed within a predetermined range. ..

In the ostomate and healthy person shared toilet seat according to the present invention, the rear opening width is narrower than the front opening width due to the protruding portion formed by the left and right inner peripheral edges of the toilet seat protruding from the seat surface to the inside of the opening. Since the upper surface of the protruding portion is formed so as to be inclined toward the inside of the opening more than the other seating surface portion, the protruding portion directly contacts the buttocks, thighs, etc. of a healthy person when sitting. Less is. As a result, there is no sense of discomfort even when a healthy person uses it normally.

Further, in the ostomate and healthy person shared toilet seat according to the present invention, in which a substantially uniform ostomate seating portion is formed, the ostomate seating portion can be stably seated at the time of use, so that the toilet seat opening should be widely used. This makes it easier for ostomates to perform tasks such as defecation.

Further, the ostomate and healthy person shared toilet seat according to the present invention having a recessed portion in which the boundary portion between the top surface of the seat surface and the rising surface on the inner peripheral side is recessed within a predetermined range is performed on the front side of the opening. Work such as urine examination and urinary catheterization becomes easier.

Hereinafter, embodiments of the ostomate and healthy person shared toilet seat of the present invention will be specifically described with reference to the drawings. The present invention is not limited to these embodiments.

As shown in the figure, the toilet seat 1 includes a seat surface 11 formed in an annular shape. The opening 12 of the toilet seat 1 has a wider opening at the front than at the rear in order to secure a wider working space for the ostomate to discharge the contents of the pouch into the toilet while sitting on the toilet seat. It is formed.

More specifically, the opening 12 has a front opening width wider than that of a normal toilet seat, and behind the opening 12, the inner peripheral edge portion of the toilet seat 1 protrudes from the seat surface 11 to the inside of the opening, and the protruding portion 13 Is formed so that the rear opening width is narrower than the front opening width.

The protruding portion 13 is integrally formed with the seat surface 11 so that a part of the inner peripheral edge of the toilet seat 1 bulges into the opening 12. As shown in FIG. 2, the protruding portion 13 starts bulging from the inner peripheral edge of the seat surface 11 corresponding to 1/3 to 1/2 of the vertical diameter of the opening from the front end to the rear of the opening 12 and into the opening 12. It extends backward while bulging so as to increase the squeeze width, and forms a region that narrows the opening width. Then, behind the narrowed region, the protruding portions 13 facing each other from the left and right extend substantially in parallel to form a region having substantially the same opening width. Then, after passing through the substantially same region, the arc is drawn to approach the seat surface 11 while reducing the protrusion width thereof, and finally converges to the seat surface 11 near the rear end portion of the 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. The term "width" here does not consider the inclination or uneven surface of the seat surface 11 and the upper surface 131, which will be described later, and merely refers to the length of the seat surface 11 and the upper surface 131 in the width direction in a plan view.

As shown in FIG. 6, in the overhanging portion 13, the back surface 14 corresponding to the back side of the seat surface 11 in the cross-sectional shape is provided substantially horizontally, whereas the seat surface 11 is provided with a gentle downward slope toward the inside of the opening. There is. The protruding portion 13 that bulges from the seat surface 11 is formed so that the upper surface 131 thereof is further lowered and inclined toward the inside of the opening than the seat surface 11, and the back surface 133 is also formed so as to be inside the opening rather than the back surface 14. It is formed so as to have a downward slope. The thickness of the protruding portion 13 is formed to be thinner as a whole than the seat surface 11 portion. Further, the tip portion 132 of the protrusion portion 13 may be provided so as to be located below the back surface 14 of the seat surface 11.

The inclination angle θ1 of the upper surface 131 on the AA end surface is formed so as 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 °. In addition, when the term "tilt angle" is used here, the unevenness of the convex surface of the seat surface 11 and the concave surface of the upper surface 131, which will be described later, is not taken into consideration. Refers to the angle of inclination of the virtual straight line connecting the above with respect to the horizon.

Further, the upper surface 131 may be formed in a concave curved surface shape that is gently recessed in a cross-sectional view, and the seat surface 11 may be formed in a convex curved surface shape that is gently raised in a cross-sectional view. Further, it is preferable that the boundary portion between the upper surface 131 and the seat surface 11 is formed in a smooth curved surface shape to provide continuity between the two.

In the toilet seat 1, the seat surface 11 and the back surface 14 may be integrally formed, but the seat surface 11 and the back surface 14 are formed separately, and their edge portions are bonded by a known welding method such as vibration welding. May be good. The bonding method is not limited to this, and other known bonding means can be used.

The toilet seat 1 of the present embodiment is rotatably attached to the cleaning device 2 provided behind the toilet bowl. A general cleaning device 2 can be used, but for example, as in the present embodiment, a casing main body 21 formed in a substantially triangular shape in a side view and a water supply pipe or the like provided on the casing main body 21 are provided. A cleaning device main body 2 including a casing 22 to which a toilet seat 1 and a lid can be attached can be used. The casing 22 is provided on the inclined top surface portion 211 of the casing main body 21, has a top surface portion 221 formed substantially parallel to the top surface portion of the casing main body 21, and a protruding portion that further protrudes from the top surface portion 221 in a semicircular shape. It is equipped with 222.

The cleaning device 2 and the seating surface 11 are preferably provided with an ostomate seating portion 15, which is a substantially flush continuous surface on which the ostomate can be seated. That is, the seat surface 11 is formed in an ascending inclination toward the casing 22 from the front to the rear, and forms an inclined surface continuous with the top surface portion 221 of the casing 22 which is also formed in the ascending inclination. In such a continuous surface, on the seat surface 11 side, the seating surface 151 projecting from the rear end side 111 of the seat surface to the opening 12 side in a gentle arc shape is formed so as to be slightly flatter than the other seat surface 11 portions.

Further, on the casing 22 side, the seating surface 152 is formed so as to have substantially the same lateral width as the seating surface 151, projecting to the rear of the casing 22, and reaching the protruding portion 222. The seating surface 152 is formed so as to be slightly flatter than the other inclined top surface portion 221. The ostomate seating portion 15, which is a substantially flush continuous surface, is formed by the seating surface 151 and the seating surface 152. By providing the ostomate seating portion 15 in this way, the ostomate can serve as a guide when sitting behind the toilet seat 1 and can stably sit on a flush continuous surface.

Then, as in the present embodiment, a part of the upper side portion of the seating portion 152 is formed so as to be in contact with the protruding portion 222, and a part of the front surface of the protruding portion 222 is formed according to the shape of the upper side portion of the seating portion 152. A recess 223 may be formed in the recess. With the concave portion 223, it is possible to alleviate the discomfort and discomfort that the protruding portion 222 hits the buttocks when seated. It is preferable that the contour of the ostomate seating portion 15 is formed not as a straight line but as a curved line as in the present embodiment because a soft impression can be given even in appearance.

Further, in the inner peripheral edge portion near the front end portion of the toilet seat 1, a recessed portion 17 may be formed in which the boundary portion between the top surface of the seat surface 11 and the rise on the inner peripheral side is recessed within a predetermined range. As described above, by providing the recessed portion 17 in a part of the inner peripheral edge portion of the toilet seat 1, the work such as urine examination and urinary catheterization performed on the front side of the opening 12 becomes easier.

Next, a method of using the toilet seat 1 of the present invention will be described. When a healthy person uses the toilet seat of the present invention, there is no difference from the case where a normal toilet seat is used. That is, it may be used while sitting on the seat surface 11, but at this time, the weight of the healthy person is exclusively weighted on the seat surface 11 in the vicinity of the protruding edge portion 13. However, in the toilet seat 1 of the present invention, since the protruding portion 13 is formed so as to be inclined downward with respect to the seat surface 11, the protruding portion 13 rarely comes into direct contact with the buttocks, thighs, or the like of a healthy person. As a result, even a healthy person can use it without any discomfort.

When an ostomate uses the toilet seat 1 of the present invention, he / she sits behind a healthy person to work. That is, the ostomate sits on the ostomate seating portion 15 provided behind the seating surface 11 so as to put a weight on the ostomate, so that the buttocks are stably placed on the continuous surface of the surface. As a result, it is possible to obtain a good usability without shifting the buttocks during work.

Since the toilet seat 1 of the present embodiment is continuously formed so as to gently rise from the rear of the seat surface 11 to the ostomate seating portion 15, the user adjusts the sitting front-back position according to his / her physique. It can be selected arbitrarily. That is, when the user is short, if he / she sits too far, his / her feet will not reach the floor, and it will be necessary to lower his / her pants or skirt to the toes in order to further spread his / her crotch. Therefore, if an ostomate having a small body shape is used while sitting on the seat surface 11 in front of the ostomate seating portion 15, such a problem does not occur.
