Description

The present invention is useful for patients with colon cancer, bladder cancer, inflammatory bowel disease, etc., who have an excretion opening in the abdomen or lower abdomen by changing the excretion route of feces or urine by adding a stoma such as an artificial anus or an artificial bladder ( The present invention relates to a toilet seat for an ostomate (hereinafter referred to as an "ostomate"), and more particularly to a toilet seat that can be shared by an ostomate and a healthy person.

Conventionally, when an ostomate uses a Western-style toilet bowl, he or she excretes by opening the pouch attached to the stoma in the abdomen. This work can be done by standing in front of the toilet and crouching, or by kneeling on the floor and holding the toilet. Working in a seated position is preferred.

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 wide as possible. However, in the case of a common type of toilet seat, it is extremely difficult to sit on the back side of the toilet seat, and in some cases it is difficult to sit down if the toilet seat is not deep. Furthermore, the narrow opening is inconvenient for an ostomate to work with.

Therefore, in order to solve this problem, Patent Documents 1 and 2 disclose that the width of the opening of the toilet seat is wider in the front than in the rear, so that the ostomate can sit on the back side stably when using it. Disclosed is an ostomate-compatible toilet seat in which a large space for disposal is provided on the front side so that defecation and urination can be easily performed.

These toilet seats are supposed to be used not only by ostomates but also by healthy people. That is, in the case of these toilet seats for ostomates, the corners of the inner periphery of the seat surface protrude at the rear of the toilet seat, which is formed with a narrow opening width, and depending on the sitting posture, the corners may come into contact with the ischial bones, etc., which may cause discomfort. .

However, if the bulge on the inner edge of the seat surface is removed, the width of the opening 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 sense of psychological reluctance to use it. Therefore, there has been a demand for an ostomate-friendly toilet seat that can be used with peace of mind by widening the width of the opening only at the front like the conventional toilet seat for ostomates. In addition, there is a need for an ostomate-compatible toilet seat that does not differ from normal toilet seats in terms of usability for healthy people.

Hereinafter, embodiments of the ostomate-compatible toilet seat of the present invention will be specifically described based on the drawings. It should be noted that the present invention is in no way restricted to these embodiments .

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

More specifically, the front opening width of the opening 12 is formed to be wider than that of a normal toilet seat, and the inner peripheral edge portion of the toilet seat 1 protrudes from the seat surface 11 toward the inner side of the opening to form a protruding portion 13 behind it. is formed, 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 protrudes into the opening 12 . As shown in FIG. 2, the projecting portion 13 starts to bulge rearward from the front end of the opening 12 from the inner peripheral edge of the seat surface 11 corresponding to 1/3 to 1/2 of the opening vertical diameter, and extends into the opening 12. It extends rearward while bulging so that the protrusion width increases, forming a region that narrows the opening width. Behind the constricted area, the protruding portions 13 facing each other from the left and right extend substantially parallel to form an area having substantially the same opening width. After passing through the substantially same region, the protrusion width is reduced, drawing an arc, approaching the seat surface 11 , and finally converging on the seat surface 11 near the rear end 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. Here, the term "width" refers only to the width direction length of the seat surface 11 and the upper surface 131 in a plan view, without considering the inclination or uneven surfaces of the seat surface 11 and the upper surface 131, which will be described later.

As shown in FIG. 6, the protruding portion 13 has a substantially horizontal back surface 14 corresponding to the back side of the seat surface 11 in cross-sectional shape, and the seat surface 11 is provided with a gentle downward slope toward the inner side of the opening. there is The protruding portion 13 that protrudes from the seat surface 11 is formed so that the upper surface 131 thereof is inclined further toward the inside of the opening than the seat surface 11, and the back surface 133 thereof is also inclined toward the inside of the opening more than the back surface 14. It is formed to have a downward slope. The thickness of the protruding portion 13 is formed thinner than the seat surface 11 portion as a whole. Furthermore, the tip portion 132 of the protruding portion 13 may be provided so as to be positioned below the back surface 14 of the seat surface 11 .

The inclination angle θ1 of the upper surface 131 at the AA end surface 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°. Here, when the term "inclination angle" is used, 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, are not taken into account. refers to the angle of inclination of the imaginary straight line connecting

Further, the upper surface 131 may be formed in a concave curved shape that is gently depressed when viewed in cross section, and the seat surface 11 may be formed in a convex curved shape that is gently raised when viewed in cross section. Furthermore, it is preferable to provide continuity between the upper surface 131 and the seat surface 11 by forming a smooth curved surface at the boundary between the two.

Although the seat surface 11 and the back surface 14 of the toilet seat 1 may be molded integrally, the seat surface 11 and the back surface 14 may be molded separately, and the edges thereof are bonded by a known welding method such as vibration welding. good too. Note that the bonding method is not limited to this, and other known bonding means can be used.

The toilet seat 1 of this embodiment is rotatably attached to a cleaning device 2 provided behind the toilet bowl. A general cleaning device 2 can be used as the cleaning device 2. For example, as in the present embodiment , a casing body 21 formed in a substantially triangular shape when viewed from the side, and a water supply pipe and the like provided on the upper portion thereof. can be used. The casing 22 is provided on an inclined top surface portion 211 of the casing main body 21, and includes a top surface portion 221 formed substantially parallel to the top surface portion of the casing main body 21, and a projecting portion further protruding from the top surface portion 221 in a semicircular shape. 222.

It is preferable that the cleaning device 2 and the seat surface 11 are provided with an ostomate seat portion 15, which is a substantially flush continuous surface on which an ostomate can be seated. That is, the seat surface 11 is formed with an upward inclination toward the casing 22 from the front to the rear, forming an inclined surface continuous with the top surface portion 221 of the casing 22 which is also formed with an upward inclination. In this continuous surface, on the seat surface 11 side, a seat surface 151 projecting in a gentle arc shape from the seat surface rear edge 111 toward the opening 12 side is formed so as to be slightly flatter than the rest of the seat surface 11 portion.

Further, on the casing 22 side, a seating surface 152 is formed to have substantially the same width as the seating surface 151 , protrude rearward from the casing 22 , and reach the projecting portion 222 . The seating surface 152 is formed to be slightly flatter than the other inclined top surface portion 221 . The seating surface 151 and the seating surface 152 form the ostomate seating portion 15 which is a substantially flush continuous surface. By providing the ostomate seating portion 15 in this manner, the ostomate can be used as a reference when seating on the rear side of 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 portion of the front surface of the protruding portion 222 is formed in accordance with the shape of the upper side portion of the seating portion 152 . A recess 223 may be formed in the portion. Such a concave portion 223 can alleviate discomfort and discomfort caused by the protrusion 222 coming into contact with the buttocks when seated. It should be noted that forming the contour of the ostomate seating portion 15 with a curved line instead of a straight line as in the present embodiment is preferable because it gives a softer appearance.

Furthermore, in the inner peripheral edge portion near the front end of the toilet seat 1, a recessed portion 17 may be formed by recessing the boundary portion between the top surface of the seat surface 11 and the inner peripheral side rise in a predetermined range. By providing the concave portion 17 in a part of the inner periphery of the toilet seat 1 in this way, the work such as urinalysis and urinary catheterization performed on the front side of the opening 12 becomes easier.

Next, how to use 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 using a normal toilet seat. In other words, the seat 11 can be used by sitting on it. However, in the toilet seat 1 of the present invention, the protruding portion 13 is formed with a downward slope with respect to the seat surface 11, so that the protruding portion 13 is less likely to come into direct contact with the buttocks, thighs, etc. of a healthy person. As a result, even a healthy person can use the device without discomfort.

When an ostomate uses the toilet seat 1 of the present invention, he/she sits behind a healthy person. That is, the ostomate sits on the ostomate seating section 15 provided behind the seat surface 11 so that the weight of the ostomate rests thereon, so that the buttocks are stably placed on the continuous flat surface. As a result, the buttocks do not shift during work, and a good feeling of use can be obtained.

In addition, since the toilet seat 1 of the present embodiment is formed continuously so as to gradually rise from the rear of the seat surface 11 to the ostomate seat portion 15, the user can adjust the front and back position of the seat according to his/her physique. can be selected arbitrarily. That is, when the user is short, if the user sits too far back, the user's legs cannot reach the floor. Therefore, if an ostomate with a small physique sits on the seat surface 11 in front of the ostomate seat portion 15 and uses it, such a problem does not occur.
