Description

  The present invention relates to an ostomate waste logistics system used by people called “ostomates” who are holders of an artificial anus and an artificial bladder.

  People called ostomates, who are holders of colostomy and artificial bladder, wear so-called pouches to store excrement (hereinafter referred to as filth) on the body's abdomen, and sometimes accumulate in the toilet. It is necessary to perform operations such as disposing of filth, and washing away dirt attached to the inner surface of the pouch, stoma (excretion port built in the abdomen), and the abdomen near the stoma.

And as a dedicated facility for people called ostomates to perform work on the go, for example, a freight logistics for ostomate described in Patent Document 1 has been proposed.
In the ostomate waste distribution described in Patent Document 1, water is discharged so as to swivel around the peripheral wall surface of the bowl portion, and waste disposed in the bowl portion is discharged. However, even if filth remains in the bowl portion after discharging, it can be easily grasped visually and can be easily removed, which is excellent in terms of hygiene.

In recent years, with the enforcement of the barrier-free law, the installation of multi-purpose toilet rooms has been promoted in public facilities, but securing the space is the barrier. That is, the multi-purpose toilet room requires a larger area than a general toilet room used by healthy persons in order to be used by wheelchair users.
For this reason, there is an increasing demand for downsizing of ostomates installed in multi-purpose toilet rooms, which can be installed even in a small area.

Japanese Patent No. 04941336

When reducing the size of the ostomate waste distribution, it is necessary to provide a pipe layout space between the bowl part and the wall surface to arrange a water supply channel and a trap pipe. The scale cannot be reduced.
In addition, it is preferable to increase the opening area of the bowl part in consideration of the convenience of ostomate people in the downsizing of ostomate waste logistics. However, the opening part of the bowl part should be made rectangular, for example. When the area is increased, the swirlability of the cleaning water is deteriorated and the cleaning performance is deteriorated.
Therefore, by reducing the size of the ostomate waste distribution described in Patent Document 1 and making the opening shape of the bowl portion a horizontally long, oval shape, it is possible to secure a pipe arrangement space and the opening area of the bowl portion. It is conceivable that the cleaning performance is good.

However, in the ostomate waste distribution in which the opening of the bowl portion is formed into a horizontally long and approximately elliptical shape for downsizing, when washing water is spouted forward from the wall surface as in Patent Document 1, the bowl portion is washed to the front side. When the water arrives, the washing water swirling forward has sufficient kinetic energy and the centrifugal force is large, so that the washing water falling from the front side of the bowl portion is reduced. For this reason, there is a problem that the filth attached to the front side of the bowl portion remains.
In particular, ostomates hang down the pouch from the front side of the bowl portion when discarding the filth and discard the filth, so a lot of filth is attached to the front side of the bowl portion. Therefore, the filth residue becomes remarkable.

  In addition, since ostomate waste logistics are installed in public facilities, the instantaneous flow rate is about 100 liters / minute through a flush valve from a water supply pipe having a larger diameter than a general household as a supply source of cleaning water. Many sites are set up to be supplied, and if the amount of washing water to be used for water saving is reduced, the water discharge time will be shortened and the amount of washing water flowing down from the front side of the bowl will be small. Therefore, the waste residue discarded on the front side of the bowl portion becomes remarkable.

  The present invention has been made in order to solve the above problems, and the object of the present invention is to reduce wastes disposed in front of the bowl portion efficiently with a small amount of washing water while reducing the size of the ostomate waste logistics. The purpose is to provide ostomate waste logistics that can be washed off.

  In order to achieve the above object, in the ostomate waste logistics according to claim 1, the ostomate waste logistics arranged along the wall surface of the building, the upper side being opened so that filth can be input, The peripheral wall surface is formed in a substantially elliptical shape, the bowl portion is formed to be recessed from the bowl portion, the water storage portion in which the sealed water is stored, and the bottom portion of the water storage portion is formed to rise toward the wall surface. A trap conduit that forms the sealed water in the reservoir, and a spout that opens to the peripheral wall surface of the bowl portion and discharges wash water so as to swirl horizontally along the peripheral wall surface; The peripheral wall surface of the bowl portion is formed with a shelf portion that protrudes substantially horizontally from the peripheral wall surface so as to swivel and swirl the cleaning water discharged from the spout. The front side of the bowl Wherein the flow guide unit for inducing wash water to be directed into the accumulated water portion.

According to the waste logistics for ostomate according to claim 1, since the peripheral wall surface of the bowl portion is formed in a horizontally long substantially oval shape, the amount of protrusion from the wall surface is ensured while ensuring an opening area for introducing filth. Can be suppressed.
Moreover, since the wash water swirling around the peripheral wall surface of the bowl portion is swung on the shelf portion, it is possible to prevent the wash water spouted from the water outlet from flowing down to the water reservoir portion before reaching the front of the bowl portion. .
Furthermore, since a flow guiding portion that guides the cleaning water toward the reservoir portion is formed on the front side of the bowl portion, the cleaning water flowing on the front side of the bowl portion is transferred to the reservoir portion by the flow guiding portion. Can flow down.
Therefore, the amount of the wash water that flows from the front side of the bowl portion to the reservoir portion can be increased by the shelf portion and / or the flow guide portion.
Therefore, the waste disposed on the front side of the bowl portion can be efficiently washed off with a small amount of washing water.

  Further, in the ostomate waste distribution according to claim 2, the flow guide unit is configured to allow the washing water discharged from the water discharge port that circulates around the shelf part to flow down from the shelf part. It is comprised by the induction groove of the shape expanded from the center position of the front side of a bowl part toward the said water storage part.

In the ostomate waste distribution according to claim 2, the flow guide portion is arranged in front of the bowl portion in the shelf portion so that the wash water discharged from the water outlet that circulates around the shelf portion flows down from the shelf portion. Since the guide groove has a shape that widens from the central position on the side toward the water storage part, it is possible to guide the wash water swirling the shelf part to flow down from the shelf part toward the guide groove. In addition, since a part of the washing water flowing down from the shelf and swirling around the peripheral wall before reaching the center position of the shelf can also flow into the guide groove, It is possible to increase the amount of wash water that flows into the water.
Therefore, it is possible to efficiently wash away the waste disposed on the front side of the bowl portion with a small amount of washing water.

  Further, in the ostomate waste logistics according to claim 3, the flow guide part is formed between the shelf part and the peripheral wall surface below the shelf part on the front side of the bowl part, The cleaning water flowing through the peripheral wall surface below the shelf is guided to the water storage portion.

According to the ostomate waste distribution according to the third aspect, the flow guide portion causes the wash water from the rear side to the front side of the bowl portion flowing on the peripheral wall surface below the shelf portion to collide with the flow guide portion. Thus, the direction of the washing water flowing from the rear side to the front side of the bowl portion is changed to the direction of dropping to the water storage portion, and at the same time, the speed is reduced. By doing so, since the washing water is directed toward the water storage portion in a state where the speed is reduced, most of the washing water flows from the front side of the bowl portion to the water storage portion, and the water is collected from the front side of the bowl portion. It is possible to increase the amount of washing water flowing down to the water section.
Therefore, it is possible to efficiently wash away the waste disposed on the front side of the bowl portion with a small amount of washing water.

  Further, in the ostomate waste distribution according to claim 4, the water discharge port is formed on the peripheral wall surface on the rear side of the bowl portion, and the wash water discharged from the water discharge port to the peripheral wall surface is: It flows through the peripheral wall surface on the rear side from one of the left and right sides to the other side.

According to the ostomate waste distribution according to claim 4, the water outlet is formed on the peripheral wall surface on the rear side of the bowl portion, and the wash water discharged from the water outlet to the peripheral wall surface is the rear peripheral wall surface. Flow from one of the left and right sides to the other side, so that the flow rate of the wash water immediately after being discharged from the water outlet decreases while flowing through the peripheral wall surface on the rear side. Since the flow velocity is further reduced when the wall turns and reaches the front side, the centrifugal force applied to the wash water is weakened, so that the amount of wash water that flows from the front side to the reservoir can be increased. it can.
Therefore, it is possible to efficiently wash away the waste disposed on the front side of the bowl portion with a small amount of washing water.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide an ostomate waste stream that can efficiently wash away waste disposed on the front side of the bowl portion while reducing the size of the ostomate waste stream and reducing the amount of washing water.

And a shelf 330 formed so as to protrude from the peripheral wall surface 310 substantially horizontally so as to go around the peripheral wall surface 310 of the bowl portion 3.
The reservoir 5 is formed at a substantially central position of the peripheral wall surface 310 so as to be recessed. A rim portion 7 formed inward is formed at the upper end of the peripheral wall surface 310.

As shown in FIG. 3, a trap pipe 15 is formed in the lower part of the water reservoir 5. A drainage inlet 151 on the upstream end side of the trap pipe 15 communicates with the lower part on the rear side of the water reservoir 5, and extends from there toward the wall K on the rear side. A drain outlet 153 on the downstream end side of the trap pipe 15 opens toward the wall surface K, and is connected to a drain pipe (not shown) on the wall surface K.
Further, in the shelf 330, a flow guiding portion 340 that guides a part of the wash water that swirls the shelf 330 toward the water storage portion 5 is formed at the center position on the front side of the bowl portion 3. .
Specifically, the flow guiding portion 340 includes a notch 340 a in which a part of the shelf surface 330 a is cut out, and a guide groove 340 b formed from the notch 340 a toward the water reservoir 5.

  As shown in FIG. 4, the peripheral wall surface 310 of the bowl portion 3 is formed in a horizontally long substantially elliptical shape when viewed from above. Therefore, it is possible to secure an opening area in the left-right direction into which filth is introduced while suppressing the above-mentioned coming out from the wall surface K, and it is possible to suppress the amount of protrusion from the wall surface K while maintaining the input property of the filth.

The peripheral wall surface 310 of the bowl portion 3 is formed on the front side so as to face the rear side wall surface 310B extending in the left-right direction and with the curvature R2 in the left-right direction when facing the rear side wall surface 310B. Connected to the formed front side wall surface 310F, the left side wall surface 310L formed in the front-rear direction so as to connect the rear side wall surface 310B and the front side wall surface 310F, and the left side wall surface 310L. And a right-side circumferential wall surface 310R formed in the front-rear direction so as to be connected to the end portion opposite to the end portion of the front-side circumferential wall surface 310F. Note that the curvature R1 of the rear peripheral wall surface 310B is smaller than the curvature R2 of the front peripheral wall surface 310F. Further, in the left side peripheral wall surface 310L and the right side peripheral wall surface 310R, the curvature R3 of the portion connected to the rear side peripheral wall surface 310B and the curvature R4 of the portion connected to the front side peripheral wall surface 310F are the same as those of the rear side peripheral wall surface 310B. It is formed larger than the curvature R1 and the curvature R2 of the front peripheral wall surface 310F (R1 <R2 <R3, R4).
These rear side peripheral wall surface 310B, front side peripheral wall surface 310F, left side peripheral wall surface 310L and right side peripheral wall surface 310R are shown as regions surrounded by a two-dot chain line in FIG.

  Further, the bowl portion 3 is formed with a water discharge port 11 so as to open at a position on the rear side circumferential wall surface 310B and connected to the right side circumferential wall surface 310R. A shelf 330 is formed so as to circulate around the peripheral wall surface 310 of the bowl portion 3 so as to circulate around the peripheral wall surface 310 so as to swirl the cleaning water discharged from the water discharge port 11. The upper surface of the shelf 330 is a substantially horizontal shelf surface 330a, and the cleaning water discharged from the water discharge port 11 is swung on the shelf surface 330a. In addition, the washing water swirling on the shelf surface 330a is swirled while part of the water flows down toward the water storage portion 5 due to gravity, and the entire peripheral wall surface 310 of the bowl portion 3 is washed.

The water discharge port 11 communicates with a water supply connection port 111 that opens toward the rear side of the bowl portion 3 via a water conduit 113. A water supply pipe (not shown) extending from a water supply means such as a flash valve (not shown) is connected to the water supply connection port 111, and by operating the operation button 13 shown in FIG. A certain amount of washing water can be discharged from the water discharge port 11.
The water conduit 113 is bent in a substantially L shape when viewed from above. Specifically, the water conduit 113 extends forward from the water supply connection port 111, and then bends toward the left side to communicate with the water discharge port 11.
Further, the water discharge port 11 is the rear side peripheral wall surface 310B of the bowl portion 3 and is formed close to the right side peripheral wall surface 310R, and the wash water discharged from the water discharge port 11 to the peripheral wall surface 310 is Since the rear side peripheral wall surface 310B flows from the right side to the left side, the flow rate of the cleaning water immediately after being discharged from the water outlet 11 while flowing through the rear side peripheral wall surface 310B is decreased, and then the bowl portion Since the flow velocity is further reduced at the time when the side wall surface 310 of the side 3 is turned and reaches the front side, the centrifugal force applied to the wash water is weakened. The amount of washing water flowing down to 5 can be increased. Moreover, since the water discharge port 11 is formed along the tangent of the curved surface of the rear side peripheral wall surface 310B, the wash water discharged from the water discharge port 11 does not collide with the rear side peripheral wall surface 310B, and smoothly enters the shelf 330. The swirl can be started and swirl can be started, and the flow rate of the cleaning water does not drop rapidly at the rear side peripheral wall surface 310B, and the flow rate of the cleaning water gradually decreases from the left side peripheral wall surface 310L to the front side peripheral wall surface 310F. Therefore, it is possible to increase the amount of washing water that flows from the front side of the bowl portion 3 to the water storage portion 5, and it is possible to wash away waste that has been discarded to the front side of the bowl portion 3 efficiently even with a small amount of washing water. Furthermore, since the washing water flowing down from the front side of the bowl portion 3 to the water reservoir 5 pushes the waste collected in the water reservoir 5 toward the trap pipe 15, the waste collected in the water reservoir 5. Can be efficiently discharged from the trap pipe 15 to the outside.

  In addition, a flow guiding portion 340 is formed at the center position in the left-right direction of the shelf 330 formed on the front peripheral wall surface 310F. When viewed from above, the notch 340 a of the flow guiding part 340 is notched in a V shape, and the guiding groove 340 b of the flow guiding part 340 has a shape that widens from the notch 340 a toward the water reservoir 5. ing.

  The flow guiding unit 340 can guide the wash water swirling the shelf 330 to flow down to the guide groove 340b through the notch 340a and flow down from the shelf surface 330a before reaching the notch 340a. Thus, a part of the cleaning water swirling around the peripheral wall surface 310 can be guided to flow into the guide groove 340b. Therefore, the amount of the cleaning water flowing down from the front side peripheral wall surface 310F of the bowl portion 3 to the pooled water portion 5 can be increased by guiding the cleaning water by the flow guiding portion 340. Therefore, the filth attached to the front center of the bowl portion 3 where the filth is often discarded can be efficiently washed off. Furthermore, since the washing water flowing down from the front side of the bowl portion 3 to the water reservoir 5 pushes the waste collected in the water reservoir 5 toward the trap pipe 15, the waste collected in the water reservoir 5. Can be efficiently discharged from the trap pipe 15 to the outside.

  Next, a second embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol is provided to the location similar to 1st Embodiment, and detailed description is abbreviate | omitted.

Similar to the first embodiment, the bowl portion 4 according to the second embodiment of the present invention has a bowl shape with the upper side opened, extends in a substantially vertical direction, and is formed so as to surround the periphery. 310 and a shelf 330 formed to protrude substantially horizontally from the peripheral wall surface 310 so as to circulate around the peripheral wall surface 310 of the bowl portion 4 in order to swirl the washing water discharged from the water discharge port 11. Has been.
The reservoir 5 is formed to be recessed at a substantially central position of the peripheral wall surface 310 below the shelf 330. A rim portion 7 formed inward is formed at the upper end of the peripheral wall surface 310.
In the bowl portion 4, a flow guiding portion 440 is formed between the shelf portion 330 and the peripheral wall surface 310 below the shelf portion 330 in the region S on the front side of the bowl portion 4.

The flow guiding portion 440 is an inclined surface that connects the peripheral wall surface 310 below the shelf 330 and the shelf surface 330 a that is the upper surface of the shelf 330. As shown in FIG. 6, the flow guide portion 440 has an inclined surface that is not substantially the same inclination as the peripheral wall surface 310 below the shelf 330, and as shown in FIG. It is larger than the inclination and is inclined substantially vertically.
That is, the flow guiding part 440 connects the shelf 330 and the peripheral wall surface 310 below the shelf 330 in a stepped shape.
The flow guiding unit 440 causes the washing water to collide with the flow guiding unit 440, thereby changing the direction of the washing water flow and simultaneously reducing the speed so that the washing water of the flow WF2 can easily fall into the water storage unit 5. There is.

Next, the flow of the cleaning water flowing on the peripheral wall surface 310 below the shelf 330 will be described with reference to FIGS.
As shown in FIGS. 5 and 6, at a position where there is no flow guiding portion 440 on the rear side from the region S, the washing water flowing on the peripheral wall surface 310 below the shelf portion 330 flows in the flow WF1 from the rear side to the front side. ing.

Next, as shown in FIG. 5, in the region S, the washing water flowing on the peripheral wall surface 310 below the shelf 330 flows from the left side to the right side of the bowl part 4 from the flow WF1 from the rear side to the front side. The direction changes to the flow of the flow WF2 toward the.
The direction of the flow of the washing water is changed because the washing water of the flow WF1 collides with the flow guiding portion 440 and is changed to the flow WF2, as shown in FIG. Further, the speed of the washing water decreases when it collides with the flow guiding unit 440.
Since the wash water in the flow WF2 is directed toward the water reservoir 5 in a state where the speed is reduced, most of the wash water flows down from the front side of the bowl portion to the water reservoir 5 and the front side of the bowl portion 4 It is possible to increase the amount of washing water that flows from the water to the reservoir 5. Therefore, the filth attached to the front side of the bowl portion 4 where the filth is often discarded can be efficiently washed off. Further, the washing water flowing down from the front side of the bowl portion 4 to the water reservoir 5 functions to push the waste accumulated in the water reservoir 5 toward the trap pipe 15, and therefore the waste collected in the water reservoir 5. Can be efficiently discharged to the outside.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. For example, the ostomate sink may not be wall-mounted but may be placed on the floor.
