The ostomate and healthy person common toilet seat is characterized in that an inner circumferential edge portion of the toilet seat protrudes from a seat surface to an opening inside to form a protruding part in the rear of the opening, a backward opening width becomes narrower to a forward opening width by the protruding part, and the upper surface of the protruding part is formed so as to become a slope downward to the opening inside more than the other seat surface portion.SELECTED DRAWING: Figure 1

Description

本発明は、大腸癌や膀胱癌または炎症性腸疾患などのため、便や尿の***経路を変更して人工肛門や人工膀胱などのストーマ増設により***口を腹部や下腹部に設けた患者（以下、「オストメイト」という）用の便座に関し、更に詳細には、オストメイトと健常者が共用可能な便座に関する。   The present invention is a patient in which the excretory opening is provided in the abdomen or the lower abdomen by changing the excretion route of stool or urine due to colon cancer, bladder cancer, inflammatory bowel disease, etc. Hereinafter, it is related with the toilet seat for ostomate and a healthy person.

従来、オストメイトが洋式便器を使用する場合、腹部のストーマに装着したパウチの口を開放することで***を行なう。かかる作業は、便器の前に立ってかがんで中腰で行う場合や、床に膝を付き便器を抱える形で行う場合もあるが、体力的な理由や衛生面に問題があるので、便座に着座した状態での作業が好ましい。   Conventionally, when an ostomate uses a Western-style toilet, excretion is performed by opening the mouth of a pouch attached to an abdominal stoma. Such work may be done while standing in front of the toilet bowl and bending in the middle or in the form of holding a toilet with a knee on the floor, but there are problems with physical strength and hygiene, so Work in a seated state is preferred.

着座した状態での作業の場合、便座の開口をなるべく広く使えるように、便座の奥側に座って行う必要がある。ところが、一般的なタイプの便座の場合、便座の奥側には極めて座りにくく、また、便座に奥行きがない場合は座ることが困難な場合もあった。さらに、開口も狭いため、オストメイトが作業を行うには不便であった。   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 of toilet seat, it is extremely difficult to sit behind the toilet seat, and it may be difficult to sit when the toilet seat has no depth. Furthermore, since the opening is narrow, it is inconvenient for the ostomate to work.

そこで、かかる課題を解決すべく、特許文献１、２には、便座の開口の開口幅を後方に対して前方が広くなるようにして、オストメイトが使用する際に奥側で安定して座ることができ、且つ、前側には処理するための余裕ある空間ができ、排便や排尿処理作業が容易に行えるようにしたオストメイト対応型便座が開示されている。   Therefore, in order to solve such a problem, in Patent Documents 1 and 2, the opening width of the toilet seat opening is set wider toward the front than the rear so that the ostomate can sit on the back side stably. In addition, an ostomate compatible toilet seat is disclosed in which a space for processing can be provided on the front side so that defecation and urination processing can be easily performed.

これらの便座は、オストメイトのみならず、健常者も使用することが前提とされているが、健常者が通常の便座と同様に使用する際に、以下の問題が生じていた。すなわち、これらのオストメイト用便座の場合、開口幅が狭く形成されている便座の後方において、座面の内周縁部の角が出っ張って着座姿勢によっては座骨等に当たるため、違和感を覚えることがあった。   These toilet seats are assumed to be used not only by ostomates but also by healthy individuals, but the following problems have arisen when healthy individuals use them in the same manner as normal toilet seats. That is, in the case of these toilet seats for ostomate, the corners of the inner peripheral edge of the seating surface protrude behind the toilet seat with a narrow opening width, and depending on the sitting posture, it may feel uncomfortable .

しかし、かかる座面の内側縁部の出っ張りを取ると、前方のみならず後方においても開口幅が一様に広くなってしまい、臀部が開口内に落ち込むのではないかという不安感や恐怖心を感じて使用に際して心理的な抵抗感もある。そこで、従来のオストメイト用便座のように前方のみ開口幅を広くすることで安心して使用することができ、さらに、健常者にとっての使用感も普通の便座と異なるところがないオストメイト対応型便座が求められていた。   However, if the protrusion on the inner edge of the seating surface is removed, the width of the opening will increase uniformly not only in the front but also in the rear, and anxiety and fear that the hips will fall into the opening. There is also a feeling of psychological resistance when using it. Therefore, there is a need for an ostomate-compatible toilet seat that can be used with peace of mind by widening the opening width only in the forward direction like conventional toilet seats for ostomate, and that the feeling of use for healthy people is not different from that of ordinary toilet seats. It was.

そこで本発明は、従来のオストメイト及び健常者共用便座のかかる欠点を克服し、前方に十分な作業スペースを確保可能であり、さらに、健常者が使用する際にも違和感がないオストメイト及び健常者共用便座の提供をその課題とするものである。   Therefore, the present invention overcomes such disadvantages of the conventional ostomate and healthy person common toilet seat, can secure a sufficient working space in front, and further, ostomate and healthy person shared when used by healthy persons The issue is to provide toilet seats.

本発明は、上記課題を解決するものであり、開口幅が後方に比べて前方が広くなるように形成された開口を備えるオストメイト及び健常者共用便座であって、該開口の後方において便座の内周縁部分が座面から開口内側へと迫り出して迫り出し部が形成され、該迫り出し部により後方の開口幅が前方の開口幅に対して狭くなっているとともに、該迫り出し部の上面が他の座面部分よりも開口内側へ下がり傾斜となるように形成されていることを特徴とするオストメイト及び健常者共用便座である。   The present invention solves the above-mentioned problem, and is an ostomate and a healthy person common toilet seat having an opening formed so that the opening width is wider in front than in the rear, and the toilet seat is located behind the opening. The peripheral portion protrudes from the seat surface to the inside of the opening to form a protruding portion. The protruding portion narrows the rear opening width relative to the front opening width, and the upper surface of the protruding portion is An ostomate and healthy person shared toilet seat, wherein the toilet seat is formed so as to be inclined toward the inside of the opening from the other seating surface portion.

また、本発明は、前記便座は便器後方に備え付けられている洗浄装置に対して回動自在に取り付けられ、前記座面側では他の座面部分よりもやや平坦になるように着座面が形成され、前記洗浄装置側ではそのケーシングの天面部よりもやや平坦になるように着座面が形成され、これらの着座面により略面一なオストメイト着座部が形成されていることを特徴とするオストメイト及び健常者共用の洗浄機能付き便座である。   Further, according to the present invention, the toilet seat is rotatably attached to a cleaning device provided behind the toilet bowl, and a seating surface is formed on the seat surface side so as to be slightly flatter than other seat surface portions. The ostomate is characterized in that a seating surface is formed on the cleaning device side so as to be slightly flatter than a top surface portion of the casing, and a substantially ostomate seating portion is formed by these seating surfaces. This is a toilet seat with a cleaning function shared by healthy people.

また、本発明は、座面の天面と内周側立ち上がりとの境部分を所定の範囲で窪ませた凹陥部を設けたことを特徴とするオストメイト及び健常者共用の洗浄機能付き便座である。   Further, the present invention is a toilet seat with a washing function shared by an ostomate and a healthy person, characterized in that a recessed portion is provided in which a boundary portion between the top surface of the seat surface and the rising on the inner peripheral side is recessed within a predetermined range. .

本発明にかかるオストメイト及び健常者共用便座は、便座の左右の内周縁部分が座面から開口内側へと迫り出して形成された迫り出し部により後方の開口幅が前方の開口幅に対して狭くなっており、該迫り出し部の上面が他の座面部分よりも開口内側へ下がり傾斜となるように形成されているため、着座時に迫り出し部が直接健常者の臀部や腿等に接することが少ない。このことにより、健常者が普通に使用する場合も違和感がない。   The ostomate and healthy person common toilet seat according to the present invention has a rear opening width narrower than a front opening width by a protruding portion formed by protruding the left and right inner peripheral edge portions of the toilet seat 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 to the inner side of the opening with respect to the other seating surface portion, the protruding portion is in direct contact with the buttocks, thighs, etc. of a healthy person when sitting Less is. Thus, there is no sense of incongruity even when a normal person uses it normally.

また、本発明にかかるオストメイト及び健常者共用便座で略面一なオストメイト着座部が形成されたものは、使用時に該オストメイト着座部に安定して座ることができるため、便座開口を広く使用することができ、オストメイトにとって排便等の作業が容易になる。   In addition, since the ostomate seating portion that is substantially flush with the ostomate and the normal person toilet seat according to the present invention can be stably seated on the ostomate seating portion during use, the toilet seat opening should be widely used. This makes it easier for ostomates to perform defecation.

また、本発明にかかるオストメイト及び健常者共用便座で、座面の天面と内周側立ち上がりとの境部分を所定の範囲で窪ませた凹陥部を設けたものは、開口の前側で行われる検尿や導尿などの作業がより容易となる。   Further, in the toilet seat for ostomates and healthy persons according to the present invention, those provided with a recessed portion in which the boundary portion between the top surface of the seat surface and the rising on the inner peripheral side is depressed within a predetermined range are performed on the front side of the opening. Work such as urinalysis and urination is easier.

以下、本発明のオストメイト及び健常者共用便座の実施態様を、図面に基づいて具体的に説明する。なお、本発明はこれら実施態様に何ら制約されるものではない。   Hereinafter, embodiments of the ostomate and the common toilet seat of the present invention will be specifically described with reference to the drawings. Note that the present invention is not limited to these embodiments.

図に示すように、便座１は環状に形成された座面１１を備える。そして、便座１の開口１２は、オストメイトが便座に座ったままでパウチの中身を便器内に排出する際の作業スペースをより広く確保するために、前方が後方に比べて開口幅が広くなるように形成されている。   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 when the ostomate is sitting on the toilet seat and the contents of the pouch are discharged into the toilet. Is formed.

より詳しくは、開口１２は前方の開口幅が通常の便座よりも幅広に形成されており、その後方において、便座１の内周縁部分が座面１１から開口内側へと迫り出して迫り出し部１３が形成されることにより、後方の開口幅が前方の開口幅に対して狭くなっている。   More specifically, the opening 12 is formed so that the front opening width is wider than that of a normal toilet seat. At the rear of the opening 12, the inner peripheral edge portion of the toilet seat 1 protrudes from the seat surface 11 toward the inside of the opening, and the protruding portion 13. Is formed, the rear opening width is narrower than the front opening width.

迫り出し部１３は、便座１の内周縁の一部が開口１２内へと膨出するようにして座面１１と一体に形成されている。図２に示すように、迫り出し部１３は開口１２の前端から後方へ開口縦径の１／３ないし１／２にあたる座面１１の内周縁からその膨出を開始し、開口１２内へと迫り出し幅が増えるように膨出しながら後方へと延伸し、開口幅を狭窄する領域を形成する。そして、その狭窄する領域より後方には、左右から対向する迫り出し部１３が略平行に延伸して開口幅が略同一の領域が形成される。そして、かかる略同一の領域を過ぎてから、その迫り出し幅を減少させながら弧を描いて座面１１に近接し、最終的には開口１２の後端部付近の座面１１へ収束する。   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 opening 12. As shown in FIG. 2, the protruding portion 13 starts to bulge from the inner peripheral edge of the seat surface 11 corresponding to 1/3 to ½ of the opening vertical diameter from the front end of the opening 12 to the rear, and into the opening 12. A region that narrows the opening width is formed by extending backward while expanding so as to increase the protruding width. Then, behind the narrowing region, the protruding portions 13 facing 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 protrusion width is reduced, the arc is drawn and the seat surface 11 is approached and finally converges to the seat surface 11 near the rear end of the opening 12.

迫り出し部１３の座面１１からの迫り出し幅は任意であるが、その最も迫り出している部分の幅Ｗは３０ｍｍ〜５０ｍｍの範囲が好ましい。なお、ここで「幅」というとき、後述する座面１１と上面１３１の傾斜や凹凸面については考慮せず、あくまでも、座面１１と上面１３１の平面視における幅方向の長さを指す。   The protruding width of the protruding portion 13 from the seating 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 to the length in the width direction of the seat surface 11 and the upper surface 131 in plan view, without considering the inclination and uneven surface of the seat surface 11 and the upper surface 131, which will be described later.

図６に示すように、迫り出し部１３は、断面形状では座面１１の裏側にあたる裏面１４は略水平に設けられ、それに対して座面１１は開口内側へと緩やかな下がり傾斜に設けられている。そして、座面１１から膨出する迫り出し部１３は、その上面１３１が座面１１よりも更に開口内側へと下がり傾斜になるように形成され、その裏面１３３も裏面１４よりも開口内側へと下がり傾斜になるように形成されている。そして、迫り出し部１３の厚さは座面１１部分よりも全体的に肉薄に形成されている。さらに、迫り出し部１３の先端部１３２は、座面１１の裏面１４よりも下方へ位置するように設けてもよい。   As shown in FIG. 6, in the cross-sectional shape of the protruding portion 13, the back surface 14 corresponding to the back side of the seating surface 11 is provided substantially horizontally, while the seating surface 11 is provided with a gentle downward slope toward the inside of the opening. Yes. The protruding portion 13 that bulges from the seating surface 11 is formed such that its upper surface 131 is inclined further down to the inside of the opening than the seating surface 11, and its back surface 133 is also inside the opening from the back surface 14. It is formed to have a downward slope. And the thickness of the protrusion part 13 is formed thinner overall than the seat surface 11 part. Furthermore, the front end portion 132 of the protruding portion 13 may be provided so as to be positioned below the back surface 14 of the seating surface 11.

Ａ-Ａ端面における上面１３１の傾斜角度θ１は、座面１１の傾斜角度θ２に比べて大きくなるように形成されている。具体的には、上面１３１の傾斜角度θ１は３０°〜４５°の範囲が好ましく、また、座面１１の傾斜角度θ２は１０°が好ましい。なお、ここで「傾斜角度」というとき、後述する座面１１の凸面や上面１３１の凹面の凹凸については考慮せず、あくまでも、座面１１と上面１３１それぞれの最外周側と最内周側とを結んだ仮想直線の水平線に対する傾斜角度を指す。   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 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 °. Here, the “inclination angle” does not take into account the unevenness of the convex surface of the seating surface 11 and the concave surface of the upper surface 131, which will be described later, and only the outermost and innermost sides of the seating surface 11 and upper surface 131, The inclination angle of the imaginary straight line connecting

また、上面１３１は断面視で緩やかに窪んだ凹曲面状に形成してもよく、座面１１は断面視で緩やかに盛り上がる凸曲面状に形成してもよい。さらに、上面１３１と座面１１の境界部分は滑らかな曲面状に形成することで、両者の間に連続性を設けることが好ましい。   Further, the upper surface 131 may be formed in a concave curved surface shape that is gently depressed in a sectional view, and the seat surface 11 may be formed in a convex curved surface shape that gently rises in a sectional view. Furthermore, it is preferable that the boundary portion between the upper surface 131 and the seating surface 11 is formed in a smooth curved surface, thereby providing continuity between the two.

便座１は座面１１と裏面１４を一体に成形してもよいが、座面１１と裏面１４をそれぞれ別々に成形し、それらの端縁部を振動溶着等の公知の溶着方法で接着してもよい。なお、接着方法はこれに限定されず、その他の公知の接着手段を用いることができる。   The toilet seat 1 may be formed integrally with the seating surface 11 and the back surface 14, but the seating 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. Also good. The bonding method is not limited to this, and other known bonding means can be used.

本実施態様の便座１は、便器後方に備え付けられている洗浄装置２に対して回動自在に取り付けられている。かかる洗浄装置２は一般的なものを利用することができるが、例えば、本実施態様のように、側面視で略三角形に形成されたケーシング本体２１と、その上部に設けられ、給水管等を内蔵するとともに便座１や蓋部が取り付けられるケーシング２２からなる洗浄装置本体２を利用することができる。このケーシング２２は、ケーシング本体２１の傾斜する天面部２１１に設けられ、ケーシング本体２１の天面部と略平行に形成された天面部２２１と、該天面部２２１から更に半円状に突出する突出部２２２とを備える。   The toilet seat 1 of this embodiment is rotatably attached to the cleaning device 2 provided behind the toilet bowl. As the cleaning device 2, a general device can be used. For example, as in the present embodiment, a casing body 21 formed in a substantially triangular shape in a side view and a water supply pipe or the like provided on the upper portion thereof are provided. The cleaning device main body 2 including the casing 22 which is built in and to which the toilet seat 1 and the lid portion are attached can be used. The casing 22 is provided on an inclined top surface portion 211 of the casing body 21, a top surface portion 221 formed substantially parallel to the top surface portion of the casing body 21, and a protruding portion that further protrudes from the top surface portion 221 in a semicircular shape. 222.

そして、洗浄装置２と座面１１には、オストメイトが着座可能な略面一な連続面であるオストメイト着座部１５を設けることが好ましい。すなわち、座面１１は、前方から後方に行くにつれてケーシング２２方向へ上り傾斜に形成され、同じく上り傾斜に形成されているケーシング２２の天面部２２１と連続する傾斜面を形成する。かかる連続面において、座面１１側では座面後端辺１１１から開口１２側へと緩やかな弧状に張り出す着座面１５１が他の座面１１部分よりもやや平坦になるよう形成されている。   And it is preferable to provide the washing | cleaning apparatus 2 and the seat surface 11 with the ostomate seating part 15 which is a substantially flush continuous surface where an ostomate can seat. That is, the seat surface 11 is formed in an upward inclination toward the casing 22 from the front to the rear, and forms an inclined surface that is continuous with the top surface portion 221 of the casing 22 that is also formed in the upward inclination. In such a continuous surface, a seating surface 151 that protrudes in a gentle arc shape from the seating surface rear edge 111 to the opening 12 side is formed on the seating surface 11 side so as to be slightly flatter than the other seating surface 11 portions.

さらに、ケーシング２２側では、着座面１５１と略同一の横幅に形成され、ケーシング２２の後方へと張りだすとともに、突出部２２２まで達するように着座面１５２が形成されている。この着座面１５２は、傾斜している他の天面部２２１よりもやや平坦になるように形成されている。かかる着座面１５１と着座面１５２により略面一な連続面であるオストメイト着座部１５が形成される。このように、オストメイト着座部１５を設けることにより、オストメイトが便座１の後方に着座するときの目安となるとともに、面一の連続面に安定して座ることができる。   Further, on the casing 22 side, the seating surface 152 is formed so as to have substantially the same width as the seating surface 151, extends rearward of the casing 22, and reaches the protruding portion 222. The seating surface 152 is formed to be slightly flatter than the other top surface portion 221 that is inclined. The seating surface 151 and the seating surface 152 form an ostomate seating portion 15 that is a substantially flush continuous surface. Thus, by providing the ostomate seating part 15, it becomes a standard when the ostomate sits behind the toilet seat 1, and can be stably seated on the same continuous surface.

そして、本実施態様のように、着座部１５２の上辺部の一部が突出部２２２に接するように形成するとともに、かかる着座部１５２の上辺部の形状に合わせて突出部２２２の前面の一部に凹部２２３を形成してもよい。かかる凹部２２３により、着座時に臀部に突出部２２２が当たることの違和感や不快感を和らげることができる。なお、本実施態様のようにオストメイト着座部１５の輪郭を直線ではなく曲線で構成することにより、見た目においても柔らかい印象を与えることができて好ましい。   And like this embodiment, while forming a part of upper side part of the seating part 152 in contact with the protrusion part 222, a part of front surface of the protrusion part 222 according to the shape of the upper side part of the seating part 152 You may form the recessed part 223 in this. Such a recess 223 can relieve the discomfort and uncomfortable feeling that the protrusion 222 hits the buttocks when sitting. In addition, it is preferable that the appearance of the ostomate seating portion 15 is not a straight line but a curved line as in this embodiment, so that a soft impression can be given.

さらに、便座１の前端部近傍の内周縁部において、座面１１の天面と内周側立ち上がりとの境部分を所定の範囲で窪ませた凹陥部１７を形成してもよい。このように、便座１の内周縁部の一部に凹陥部１７を設けることにより、開口１２の前側で行われる検尿や導尿などの作業がより容易となる。   Further, a recessed portion 17 in which a boundary portion between the top surface of the seat surface 11 and the rising on the inner peripheral side is recessed within a predetermined range may be formed in the inner peripheral edge portion in the vicinity of the front end portion of the toilet seat 1. As described above, by providing the recessed portion 17 in a part of the inner peripheral edge of the toilet seat 1, urinalysis, urination, and the like performed on the front side of the opening 12 become easier.

次に、本発明の便座１の使用方法について説明する。健常者が本発明の便座を使用する場合、通常の便座を使用する場合と異なるところはない。すなわち、座面１１に座って使用すれば良いが、このとき、健常者の体重はもっぱら迫り出し縁部１３近傍の座面１１に加重される。しかしながら、本発明の便座１は迫り出し部１３が座面１１に対して下がり傾斜に形成されているため、迫り出し部１３が直接健常者の臀部や腿等に接することが少ない。このことにより、健常者も違和感なく使用することができる。   Next, the usage method of the toilet seat 1 of this invention is demonstrated. When a healthy person uses the toilet seat of the present invention, there is no difference from the case of using a normal toilet seat. That is, it is only necessary to sit on the seating surface 11 and use it. At this time, the weight of the healthy person is pushed out exclusively and applied to the seating surface 11 near the edge 13. However, in the toilet seat 1 of the present invention, the protruding portion 13 is formed so as to be inclined with respect to the seating surface 11, so that the protruding portion 13 is less likely to come into direct contact with the buttocks or thighs of a healthy person. Thereby, a healthy person can also use it without a sense of incongruity.

本発明の便座１をオストメイトが使用する場合は、健常者よりも後方に座って作業する。すなわち、オストメイトは座面１１の後方に設けたオストメイト着座部１５に体重がかかるようにして座ることで、面一の連続面に臀部が安定して載置する。これにより、作業時に臀部がズレたりせずに、良好な使用感を得ることができる。   When an ostomate uses the toilet seat 1 of the present invention, the operator sits behind the healthy person and works. That is, the ostomate sits on the ostomate seating portion 15 provided behind the seat surface 11 so that the weight is applied, so that the buttocks are stably placed on the continuous surface. Thereby, a favorable feeling of use can be acquired, without a collar part shifting | deviating at the time of an operation | work.

なお、本実施態様の便座１は、座面１１の後方よりオストメイト着座部１５へと緩やかに***するように連続的に形成されているため、使用者は座る前後位置を自分の体格に合わせて任意に選択することができる。すなわち、使用者の身長が低い場合、あまり奥に座ると足が床に届かなくなり、更に股をひろげるためにズボンやスカートを足先まで降ろす必要が生じる。したがって、小柄な体格のオストメイトは、オストメイト着座部１５より前方の座面１１に座って使用すれば、かかる問題は生じない。   In addition, since the toilet seat 1 of this embodiment is continuously formed so that it may protrude gently from the back of the seat surface 11 to the ostomate seating part 15, the user sets the front-rear position to sit down to his physique. Can be arbitrarily selected. In other words, when the user is low in height, if he sits too far, his feet will not reach the floor, and he will need to lower his pants and skirt to his feet to expand his crotch. Therefore, if an ostomate with a small physique is used while sitting on the seat surface 11 in front of the ostomate seating part 15, such a problem does not occur.
