The excrement disposal apparatus 10 includes a receiver 21 and an excrement disposal unit 31 connected to the receiver 21 via a suction tube 36 and wiring 23 . The excrement processing unit 31 can also be called a device main body or a pump built-in unit. This excrement disposal device 10 is a device for sucking urine excreted from a user 11 and collecting the sucked urine in a tank 32 in an excrement disposal unit 31, and is a urine collection device, a suction type urine collection device. , or is also called a special urinary device.

The receiver 21 is a container for receiving urine and functions as a suction unit for sucking urine. Outside the receiver 21, a tube connection port 21A to which the tip (corresponding to the upstream end) of the suction tube 36 is connected, and a connector 21C for connecting the wiring 23 to the urine sensor 81 in the receiver 21 are exposed. there is
The receiver 21 is attached to the crotch portion 11C (FIG. 2) of the user 11 using a predetermined attachment member. The predetermined attachment member is an undergarment, a supporter, a diaper, or the like, which is attached to the crotch portion 11C of the user 11 . However, as the mounting member, a mounting member that allows the receiver 21 to be placed in the crotch portion 11C of the user 11 can be widely applied. A urine sensor 81 is a sensor that detects urine.

The excrement disposal unit 31 will be described with reference to FIG.
The excreta processing unit 31 includes a tank 32, a sub-tank 33, a vacuum pump 34, a filter 35, and a plurality of suction tubes 36, 37 and 38 connected to these, which form a suction path for sucking urine. It is formed. The vacuum pump 34 sucks the urine collected in the receiver 21 together with the air by evacuating the suction path. An exhaust tube 39 is connected to the exhaust port of the vacuum pump 34 . In addition, the arrow in FIG. 1 indicates the air flow.

In the following description, when the suction tubes 36 to 38 are particularly distinguished and described, the suction tube 36 on the upstream side connected to the receiver 21 is referred to as "first tube 36", and as it goes downstream, it is referred to as "second tube 36". 37” and “third tube 38”, respectively. Flexible tubes such as silicone rubber tubes or vinyl chloride tubes are used for the suction tubes 36 to 38 and the exhaust tube 39 . Any one of the tubes 37 to 39 arranged in the excreta disposal unit 31 may be a non-flexible tube.

The tank 32 stores the sucked urine and can be removed at an appropriate timing so that the stored urine can be discarded at a disposal site. The excrement treatment unit 31 has a tank connector 40 to which the tank 32 is detachable. A downstream end of the first tube 36 and an upstream end of the second tube 37 are connected to the tank connection portion 40 . By connecting the tank 32 to the tank connecting portion 40, the upper opening of the tank 32 is closed, the airtight state inside the tank 32 is maintained, and the inside of the tank 32 communicates with the first tube 36 and the second tube 37. do. With this configuration, liquid such as urine that has flowed into the tank 32 through the first tube 36 is stored in the tank 32 . Also, the air above the liquid surface in the tank 32 can flow to the second tube 37 .

The tank connecting portion 40 has a protruding portion 40A that protrudes downward into the tank 32 . The protruding portion 40A is provided with a float that moves up and down as the liquid level of the urine in the tank 32 rises. Further, the projecting portion 40A is also provided with a valve mechanism that cuts off communication between the tank 32 and the second tube 37 when the float moves to a predetermined upper limit position. With these configurations, communication between the tank 32 and the second tube 37 is automatically cut off when the liquid level in the tank 32 exceeds the upper limit position.

The sub-tank 33 is arranged between the tank 32 functioning as a main tank and the vacuum pump 34 . By storing the water that has flowed out of the tank 32 in the sub-tank 33 , the water (such as urine) is prevented from flowing into the vacuum pump 34 . The sub-tank 33 is detachably connected to the downstream end of the second tube 37 and detachably connected to the upstream end of the third tube 38 . The tank 32 and sub-tank 33 are removable. Therefore, maintenance of each tank 32, 33 is easy.

A filter 35 is connected to the downstream end of the exhaust tube 39 . Filter 35 is a deodorizing filter. Therefore, the air discharged from the vacuum pump 34 is deodorized by the filter 35 . In order to protect the vacuum pump 34, the third tube 38 upstream of the vacuum pump 34 may be provided with a filter.

The excreta disposal unit 31 further includes an operation section 41 , a notification section 42 , a drive section 43 and a control section 44 . The operation unit 41 inputs various instructions from the user 11 or the like, and outputs the input instructions to the control unit 44 . Instructions that can be input include instructions for an automatic operation mode in which the suction operation is performed automatically, instructions for a manual operation mode in which the suction operation is performed manually, and the like. The automatic operation mode is an operation state in which when urine is detected by the urine sensor 81, the vacuum pump 34 is operated for a predetermined period of time to automatically suck urine. The manual operation mode is an operating state in which the vacuum pump 34 is operated/stopped according to a predetermined operation by the user 11 or the like.

Various known methods such as operation of hardware switches, voice input, and communication can be applied to the excrement processing unit 31 to input instructions. Under the control of the control unit 44, the notification unit 42 uses known devices such as lamps, display panels, and audio devices to notify various types of information to the outside. The drive unit 43 drives the vacuum pump 34 functioning as a suction source under the control of the control unit 44 .

The control unit 44 functions as a computer that controls the operation of the excrement disposal apparatus 10 by executing a pre-stored control program. In addition, control unit 44 acquires the detection result of urine sensor 81 by connecting urine sensor 81 via wiring 23 . The processing executed by the control unit 44 includes suction control for selectively executing the automatic operation mode and the manual operation mode.

The automatic operation mode is an operation mode in which urine suction is started when urine is detected by the urine sensor 81 . The timing of ending the suction of urine may be the timing when a predetermined period of time has elapsed since urine was detected by the urine sensor 81, or the timing when the predetermined period of time has elapsed since the urine is no longer detected by the urine sensor 81. . The manual operation mode is an operation mode for starting and ending suction according to instructions from the user 11 or the like. It should be noted that known control can be applied to specific suction control in each mode.

FIG. 2 is a diagram showing the state of use of the receiver 21 together with the crotch portion 11C of the user 11. As shown in FIG. The user 11 shown in FIG. 2 is in a supine posture (supine position). In FIG. 2, the lower side is the dorsal side of the user 11, the upper side is the ventral side of the user 11, the reference numeral 11L indicates the leg of the user 11, and the reference numeral 11T indicates the tailbone (also referred to as the coccyx). . In FIG. 2, only one leg is illustrated for convenience of explanation.
The receiver 21 is attached to the crotch portion 11C at a position that covers the excretion site including the urethral opening 11N. The receiver 21 is formed as a hollow longitudinal member that is flexible along the crotch portion 11C, extends from the urethral opening 11N toward the anus 11K, and can extend to the vicinity of the coccyx 11T. be. This receiver 21 fits in the gap formed between the crotch part 11C and both legs 11L, and the user 11 can continue to wear the receiver 21 even in a sitting posture (sitting position) or a lateral posture (lateral lying position). .
Since the receiver 21 thus covers a wide area including between the urethral opening 11N and the anus 11K, the receiver 21 can receive urine regardless of whether the user 11 is in the supine position, sitting position, or side lying position. can be done.

FIG. 3 is an exploded perspective view of a state in which the receiver 21 is laid out flat. In the description of FIG. 3, the direction facing the user 11 when the receiver 21 is worn is defined as the top, and the direction away from the user 11 is defined as the bottom.
The receiver 21 extends along a predetermined center line LC, and is symmetrical with respect to the center line LC in the width direction (horizontal direction of the user 11 when worn). The center line LC is positioned at the lateral center of the crotch portion 11C when the receiver 21 is worn and corresponds to a line extending from the urethral opening 11N toward the anus 11K.

The receiver 21 includes an exterior portion 50 having a urine (excretion) storage space 50A (see FIG. 2). The receiver 21 of this embodiment includes a cloth-type exterior 50 .
The exterior part 50 of the receiver 21 has a surface waterproof cloth 51 as an example of a first exterior cloth. The surface waterproof cloth 51 constitutes the surface of the exterior part 50 on the side of the user 11 (the inner surface when worn), and covers the lower abdomen of the user 11 through the crotch part 11C to part of the buttocks. The surface waterproof cloth 51 is made of waterproof cloth and prevents urine from seeping out from the housing space 50A. Since the surface of the exterior part 50 on the side of the user 11 is made of cloth, it is easier to make the user 11 wear it comfortably. As an example of the first exterior cloth, instead of the surface waterproof cloth 51, a water-repellent cloth may be used.

The surface waterproof cloth 51 is formed with an elongated opening 51A extending along the center line LC. The opening 51A is formed at a position biased toward the tip side of the surface waterproof cloth 51 . When the receiver 21 is attached to the user 11, the opening 51A extends from the urethral opening 11N of the user 11 along the crotch part 11C toward the anus 11K with a predetermined width. The opening 51A functions as an entrance for urine to the accommodation space 50A and a suction port for sucking urine into the receiver 21 . In the present embodiment, the opening 51A has a long hole shape, but the opening 51A has a round hole shape, a square hole shape, or the like. The opening portion 51A may have any opening shape as long as it has an opening shape that functions as an opening.

A surface cloth 61 is arranged below the surface waterproof cloth 51 (back side). The surface cloth 61 is shorter in the longitudinal direction than the surface waterproof cloth 51 and is arranged on the tip side of the surface waterproof cloth 51 . The surface cloth 61 is made of a water-permeable and flexible cloth, and covers the opening 51A of the surface waterproof cloth 51 from below. The surface cloth 61 is formed in a shape larger than the opening 51A and smaller than the surface waterproof cloth 51 . Since the opening 51A is closed with the surface cloth 61 made of fabric, it is possible to avoid direct contact of the members inside the receiver 21 other than the surface cloth 61 with the user 11 through the opening 51A, which contributes to an improvement in wearing comfort. . It should be noted that the surface cloth 61 is preferably a cloth having a small water retention capacity.

Here, for example, a pile fabric can be applied as the fabric having water permeability and flexibility. Also, instead of one type of fabric, a fabric in which two types of fabrics having different functions are integrated may be used. For example, the surface cloth 61 may be a cloth made by stitching together a soft mesh cloth and a water-absorbing and quick-drying cloth. In the case of this surface cloth 61, the surface cloth 61 is arranged below the surface waterproof cloth 51 so that the soft mesh cloth is on the upper side (front side) and the water-absorbent and quick-drying cloth is on the lower side (back side). be. As a result, the water-absorbing and quick-drying fabric can easily stabilize urine absorption and permeability, and the soft mesh fabric prevents direct contact between the skin of the user 11 and the water-absorbing and quick-drying fabric. You can have a feeling.

A urine sensor 81 is arranged below the surface cloth 61 via a spacer 62 . The spacer 62 is formed of a flexible sheet material made of a mesh material. The spacer 62 is formed to have the same size as the surface cloth 61 and is laminated with the contour of the surface cloth 61 aligned. Spacer 62 secures a space between surface cloth 61 and urine sensor 81 .
Since the spacer 62 made of mesh material is arranged between the surface cloth 61 and the urine sensor 81, it becomes easier for the urine entering from the opening 51A to come into contact with the urine sensor 81 quickly. Further, the spacer 62 prevents the urine sensor 81 from continuously contacting the undried surface cloth 61, and can easily prevent the urine sensor 81 from being short-circuited even after urine is sucked. It should be noted that the spacer 62 is preferably made of a material that has low water retention and is not corroded by the influence of urine or the like, and is made of resin, for example.

The urine sensor 81 includes a longitudinally extending sensor sheet 82 and a connector 21C provided on the base end side of the sensor sheet 82 . The sensor sheet 82 is arranged on the lower surface side of the spacer 62 . The connector 21</b>C is led out of the exterior part 50 and positioned on the opposite side of the surface waterproof cloth 51 from the user 11 . This makes it difficult for the connector 21C to come into contact with the user's 11 skin. The sensor sheet 82 is formed narrower than the opening 51A.
The sensor sheet 82 is provided with at least one pair of electrodes.
The urine sensor 81 detects urine by utilizing the fact that the resistance value between the electrodes becomes low when the electrodes are electrically connected through water. Since urine passing through the opening 51A is detected by the urine sensor 81, it is easier to detect urine at an early stage compared to detecting urine accumulated on the bottom surface of the exterior part 50. FIG. Note that the spacer 62 described above may have a shape covering at least the upper portion of the electrode instead of being formed to have the same size as the surface cloth 61 .

A deodorizing nonwoven fabric 63 is arranged below the urine sensor 81 . The deodorizing nonwoven fabric 63 is made of a nonwoven fabric having water permeability and a predetermined deodorizing effect, and has flexibility. The deodorizing nonwoven fabric 63 is formed to have the same size as the spacer 62 and sandwiches the sensor sheet 82 of the urine sensor 81 with the spacer 62 . The deodorant nonwoven fabric 63 has at least a urine deodorant effect.

A water absorbing cloth 64 is arranged below the deodorant nonwoven fabric 63 . The water absorbing cloth 64 is made of a highly diffusive and flexible cloth. The water absorbing cloth 64 is formed to have a size equal to or larger than that of the deodorizing nonwoven fabric 63 . In this embodiment, the water absorbing cloth 64 is formed to have the same size as the deodorant nonwoven fabric 63 . The water absorbent cloth 64 allows urine to pass through in the thickness direction and suppresses the movement of the passed urine toward the opening 51A. It is preferable that the water absorbing cloth 64 has less water retention.

A suction tube 71 having a suction port at its tip is arranged below the water absorbent cloth 64 . The suction tube 71 of this embodiment is formed in a Y shape that extends from the tube connection port 21A and branches into two. The suction tube 71 is a flexible tube such as a silicone rubber tube or a vinyl chloride tube.
A shape retainer 65 is arranged between the two branched portions 71K of the suction tube 71 (hereinafter referred to as distal end portion 71K). The distal end portion 71K and the shape retainer 65 are housed in a recessed housing portion 52A provided in the inner waterproof cloth 52. As shown in FIG.

The inner waterproof cloth 52 is a member forming part of the surface of the exterior part 50 and is an example of a second exterior cloth. The inner waterproof cloth 52 constitutes the surface of the exterior part 50 opposite to the user 11 (the outer surface when worn). The inner waterproof cloth 52 includes a housing portion 52A and a flange-like joint portion 52B formed around the housing portion 52A.
The inner waterproof cloth 52 is thermally welded to the outer peripheral portion 51B of the surface waterproof cloth 51 and the joint portion 52B. By heat-sealing the surface waterproof cloth 51 and the inner waterproof cloth 52, the exterior part 50 and its accommodation space 50A are formed. The exterior part 50 and its accommodation space 50A are formed by the structure joined by thermal welding. The inner waterproof cloth 52 is made of waterproof cloth and prevents urine from seeping out from the housing space 50A. As an example of the second exterior cloth, instead of the inner waterproof cloth 52, a water-repellent cloth may be used.

By joining the surface waterproof cloth 51 and the inner waterproof cloth 52 in a laminated structure, the various members 61 to 65, 71 and 81 are laminated and integrated in the housing space 50A. Since they are joined by heat welding, it is easier to prevent leakage of urine from the housing space 50A than when they are joined by sewing. The exterior part 50 and various members 61 to 65, 71, 81 constitute the receiver 21 of the present embodiment.

FIG. 4 is a plan view of the receiver 21. FIG. 4, the surface cloth 61, the spacer 62, the urine sensor 81, the deodorizing nonwoven fabric 63, and the water absorbing cloth 64 are omitted, and the state in which the shape retainer 65 is exposed from the opening 51A is illustrated.
As shown in FIGS. 3 and 4, the center line of the opening width of the opening 51A coincides with the center line LC. In this embodiment, the surface waterproof cloth 51 is formed with raised portions 51A1 that protrude upwards corresponding to the outer peripheral side of the opening 51A. The raised portion 51A1 extends annularly along the entire periphery of the opening 51A and has a mountain-shaped cross section. When the receiver 21 is worn, the protuberances 51A1 of the surface waterproof cloth 51 tend to come into close contact with the user's skin. For this reason, the opening 51A as the edge can be easily separated from the user 11, which contributes to an improvement in wearing comfort. In addition, a buffer space for urine is secured between the user 11 and the exterior part 50, which is advantageous in preventing overflow in the case of lying on one's side.

A housing portion 52A of the housing space 50A is formed in a recessed long hole shape extending in the longitudinal direction of the opening 51A. The housing portion 52A has a bottom portion 52C extending in the longitudinal direction, and an inner wall (an outer peripheral wall serving as an outer periphery of the bottom portion 52C) 52D provided around the bottom portion 52C. A flange-shaped joint portion 52B is formed on the opening side of the inner wall 52D.
In this embodiment, the accommodating portion 52A includes a triangular widened portion 52A1 that widens toward the distal end, and a substantially rounded rectangular body portion 52A2 that extends from the widened portion 52A1 toward the distal end. The inner wall 52D has a front end side inner wall 52D1 and a pair of widthwise inner walls 52D2 and 52D3 extending from both sides of the front end side inner wall 52D1 corresponding to the body portion 52A2. Note that the housing portion 52A may have a shape in which the widened portion 52A1 is omitted, or may have a substantially rounded rectangular shape as a whole.
By fitting the two-branched distal end portion 71K of the suction tube 71 and the shape-retaining body 65 into the accommodating portion 52A, the inner waterproof cloth 52 is held in a state in which the distal end portion 71K is along the inner wall 52D of the accommodating portion 52A. is positioned at 71 K of front end side parts are arrange|positioned at intervals in the width direction of 51 A of opening parts over the longitudinal direction of 51 A of opening parts.

A tube connection port 21A of the suction tube 71 is led out of the housing portion 52A.
As shown in FIG. 4, the suction tube 71 has a tube base portion 72 extending from the tube connection port 21A toward the housing portion 52A. A one-side tube portion 73 is provided at the tip of the tube base portion 72 to branch and extend from the tip to one side in the opening width direction. The one-side tube portion 73 extends while being sandwiched between the one-side side surface 65A of the shape-retaining body 65 and the inner wall 52D2 on one side of the housing portion 52A, and is arranged on one side in the opening width direction relative to the center line LC. .

A one-side suction port 73</b>H is formed at the tip of the one-side tube portion 73 . The one-side suction port 73H is close to the inner wall 52D2 on one side of the housing portion 52A. A side portion of the one-side tube portion 73 is positioned in contact with the inner wall 52D2. The one-side suction port 73H is arranged on the distal end side of the body portion 52A2 of the housing portion 52A. In this embodiment, the one-side suction port 73H is arranged on the distal end side of the opening 51A (outside the receiver 21 in the longitudinal direction), and is arranged to face the inner wall 52D1 on the distal end side of the housing portion 52A. A predetermined gap 52A3 (FIG. 4) is formed between the one-side suction port 73H and the inner wall 52D1 on the distal end side of the housing portion 52A. The gap 52A3 has a size equal to or greater than about the inner diameter of the one-side tube portion 73 . The gap 52A3 makes it difficult for the suction port 73H to suck the inner waterproof cloth 52. As shown in FIG.

At the tip of the tube base portion 72, the other side tube portion 74 is provided to branch and extend from the tip to the other side in the opening width direction. The other side tube portion 74 is provided symmetrically in the width direction with respect to the one side tube portion 73 with respect to the center line LC. That is, the other tube portion 74 extends while being sandwiched between the other side surface 65B of the shape retaining body 65 and the inner wall 52D3 on the other side of the housing portion 52A, and is arranged on the other side of the center line LC in the opening width direction. be done.

The tip of the other-side tube portion 74 is formed with the other-side suction port 74H. The other side suction port 74H is close to the inner wall 52D3 on the other side of the housing portion 52A. The side portion of the other side tube portion 74 is positioned in contact with the inner wall 52D3. The other side suction port 74H is arranged on the distal end side of the body portion 52A2 of the housing portion 52A. In the present embodiment, the other-side suction port 74H is arranged on the distal end side of the opening 51A and arranged to face the inner wall 52D1 on the distal end side of the housing portion 52A. A predetermined gap 52A4 (FIG. 4) is formed between the other side suction port 74H and the inner wall 52D1 on the distal end side of the housing portion 52A. The gap 52A4 has a size equal to or greater than about the inner diameter of the other-side tube portion 74. As shown in FIG. The gap 52A4 makes it difficult for the suction port 74H to suck the inner waterproof cloth 52. As shown in FIG.

The distal end of the tube base portion 72 constitutes a branch portion 72A as a portion where the one-side tube portion 73 and the other-side tube portion 74 are branched. In addition, the one-side suction port 73H and the other-side suction port 74H are arranged with an interval of about the opening width WK of the opening 51A in plan view of the opening 51A shown in FIG. In this embodiment, the one-side suction port 73H and the other-side suction port 74H are arranged widthwise inwardly of the opening width WK of the opening 51A. In this embodiment, the one-side suction port 73H and the other-side suction port 74H are close to inner walls 52D2 and 52D3 on the outside in the opening width direction of the housing portion 52A.

The suction tube 71 creates a negative pressure in the storage space 50A in the exterior part 50 by the suction force of the excrement processing unit 31, and sucks urine that has entered between the water absorbent cloth 64 and the storage part 52A through the suction ports 73H and 74H. do. The tip of the suction tube 71 is positioned at or near the lowest end of the accommodation space 50A in the supine position or the like, and sucks urine in the accommodation space 50A through suction ports 73H and 74H provided at the tip. becomes easier. In particular, in this embodiment, the tip of the suction tube 71 is arranged at the widthwise outer end that contacts the inner wall 52D of the housing portion 52A. As a result, in the case of the lateral recumbent position, the width direction of the receiver 21 generally corresponds to the direction of gravity. easy. Therefore, in this embodiment, regardless of the user's posture, the suction ports 73H and 74H facilitate suction of urine in the storage section 52A.

A shape retainer 65 between the one side tube portion 73 and the other side tube portion 74 is formed of a porous soft structure. Since the shape retainer 65 has porosity, it does not block the flow of air and urine in the space between the water absorbent cloth 64 and the storage portion 52A. Further, the shape retainer 65 has strength and elasticity to such an extent that it does not deform even when the accommodation space 50A becomes negative pressure due to the suction from the suction tube 71 . The porous soft structure may be a sponge-like structure or a soft corrugated plate. The shape retainer 65 has a durability that allows washing, a water retention rate that can suppress urine seepage, a porosity that has sufficient air and water permeability, and a heat resistance that can suppress thermal deformation during heat welding. It is possible to widely apply materials having properties such as

As shown in FIG. 3, the shape-retaining body 65 connects two branched distal end portions 71K of the suction tube 71, that is, the one-side tube portion 73 (FIG. 4) and the other-side tube portion 74 (FIG. 4). , and is formed in a shape that fills the space between the absorbent cloth 64 and the storage portion 52A in a state of being placed in contact with the inner walls 52D2 and 52D3 on the outside in the width direction of the opening of the storage space 50A. As a result, the shape retainer 65 functions as a bridging member that bridges between the one-side tube portion 73 and the other-side tube portion 74, and prevents the suction tube 71 from being displaced due to negative pressure during suction or the like. A situation in which the space 50A becomes narrow can be suppressed.

Further, the shape retainer 65 has a thickness equal to or greater than the outer diameter of the suction tube 71, and thus functions as a bridging member vertically bridging between the water absorbing cloth 64 and the housing portion 52A. As a result, even if the storage space 50A becomes negative pressure due to negative pressure during suction or the like, it is possible to prevent the space between the absorbent cloth 64 and the storage portion 52A from narrowing vertically. Since the sheet members 61 to 64 and 82 are laminated except for the space between the water absorbing cloth 64 and the housing portion 52A, the sheet members 61 to 64 and 82 are not affected even if negative pressure is applied during suction. A portion of 82 hardly deforms. That is, the shape retainer 65 can suppress the shape change of the receiver 21 including the exterior portion 50 .

In this configuration, as shown in FIGS. 3 and 4, the shape retainer 65 is arranged to overlap the opening 51A of the surface waterproof cloth 51 in a plan view, and the suction tube 71 and the opening 51A It is arranged along the entire longitudinal direction. Therefore, it is easy to introduce the urine immediately after the start of discharge into the storage portion 52A, and to apply a suction force to the entire longitudinal direction of the opening 51A during suction.

In this configuration, the suction tube 71 and the shape retainer 65 are housed in the housing portion 52A of the housing space 50A in an integrated state. Specifically, as shown in FIG. 4 , the suction tube 71 and the shape retainer 65 are integrated with bands 67 and 68 . The one-side tube portion 73 is arranged along the one-side side surface 65A (FIG. 4) of the shape-retaining body 65 so that the outer peripheral surface of the one-side tube portion 73 is in contact with the one-side side surface 65A. . Further, the other tube portion 74 is arranged along the other side surface 65B (FIG. 4) of the shape retainer 65, so that the outer peripheral surface of the other tube portion 74 is arranged in contact with the other side surface 65B. be done. With the shape retainer 65 sandwiched between the tube portion 73 and the tube portion 74, the suction tube 71 and the shape retainer 65 are wrapped around a pair of bands 67 and 68 and fastened.

The band 67 is arranged on the suction port 73H, 74H side of the suction tube 71 and holds the suction tube 71 and the shape retainer 65 . Also, the band 68 is arranged in the longitudinal central portion of the distal end portion 71</b>K and holds the suction tube 71 and the shape retainer 65 . Bands 67 and 68 are thermally welded to integrally join shape retainer 65 , one side tube portion 73 and other side tube portion 74 .

Since the suction tube 71 and the shape retaining body 65 are housed in the housing portion 52A in an integrated state, the assemblability of the receiver 21 is improved. Further, since the tubular suction tube 71 is integrated with the shape retainer 65 that is flat and thicker than the outer diameter of the suction tube 71, the suction tube 71 and the shape retainer 65 as a whole are held in a flat shape. is becoming easier. Therefore, for example, when the user 11 changes his or her posture, the tubular suction tube 71 is less likely to be displaced. Further, when the fabric receiver 21 is washed, the suction tube 71 is less likely to be displaced.

Next, the operation of this embodiment will be described.
In the excrement disposal apparatus 10, when the user wearing the receiver 21 urinates, urine flows into the housing space 50A of the receiver 21 through the opening 51A. Urine that has flowed into the housing space 50A permeates the surface cloth 61 and the spacer 62 in order in the thickness direction, passes through the urine sensor 81, and flows into the housing portion 52A. At this time, when urine is detected by the urine sensor 81 or the like and the vacuum pump 34 is activated, the suction tube 71 causes the storage portion 52A blocked by the water absorbing cloth 64 to have a negative pressure. Therefore, in the storage space 50A in the receiver 21, the urine is sucked into the storage section 52A and the urine moved to the storage section 52A is sucked by the suction tube 71. As shown in FIG. As a result, urine is collected by the excreta disposal device 10 .

Here, in the conventional receiver, one suction tube is arranged along the center line LC, and the suction port at the tip thereof is arranged on the center line LC. For this reason, in the supine position and sitting position, the suction port can be placed at a position where urine can easily move by its own weight. Even if the pressure is negative, it may be difficult to suck the urine below the suction tube. Therefore, in conventional receivers, urine may overflow from the opening, or urine may remain without being completely sucked.

On the other hand, in this embodiment, the suction ports 73H and 74H of the suction tube 71 are arranged close to the inner walls 52D2 and 52D3 in the width direction of the housing portion 52A of the housing space 50A of the opening 51A. Also when the patient is in the lateral recumbent position, either one of the suction ports 73H and 74H is likely to be positioned at the lowest end of the housing portion 52A in the lateral recumbent position. Therefore, even when the user urinates in the lateral recumbent position, it is easy to properly suck urine.

As described above, the excrement disposal apparatus 10 of the present embodiment includes the receiver 21 attached to the crotch portion 11C of the user 11 to receive urine (excretion), the suction tube 71 connected to the receiver 21, In the excrement disposal apparatus 10 that sucks urine through the suction tube 71, the receiver 21 has an exterior portion 50 that extends along the crotch portion 11C and has a urine storage space 50A. On the surface of the person 11 side, an opening 51A is formed to open the accommodation space 50A to the user 11 side and allow urine to pass through the accommodation space 50A. A part of the suction tube 71 is arranged in the accommodation space 50A, A part of the suction tube 71 has a one-side suction port 73H that opens on one side in the width direction relative to the center line LC that extends in the longitudinal direction corresponding to the direction in which the receiver 21 extends, and The other side suction port 74H that opens on the other side is provided.
Therefore, when the user 11 is in the lateral recumbent position, the suction ports 73H and 74H are likely to be located below the center line LC in the direction of gravity, so urine can be easily sucked. Therefore, it is possible to prevent urine from remaining in the storage portion 52A.

In the present embodiment, the one-side suction port 73H and the other-side suction port 74H are arranged close to the inner walls 52D2 and 52D3 in the width direction of the housing portion 52A of the housing space 50A in plan view of the opening portion 51A.
Therefore, when the user 11 is in the lateral recumbent position, one of the suction ports 73H and 74H is likely to be positioned at the lowest end of the housing portion 52A in the lateral recumbent position, and urine flows from the opening 51A. You can prevent it from overflowing.

In addition, in the present embodiment, the one-side suction port 73H and the other-side suction port 74H are arranged close to the inner wall 52D1 on the longitudinal direction distal end side of the housing portion 52A of the housing space 50A in plan view of the opening portion 51A. .
Therefore, since the positions of the suction ports 73H and 74H can easily correspond to the downward position in the supine position and the sitting position, the number of the suction ports 73H and 74H can be suppressed, and urine can be efficiently sucked while maintaining the suction pressure. It is possible.

Further, in the present embodiment, the suction tube 71 includes a branch portion 72A, a one-side tube portion 73 branching from the branch portion 72A and extending therefrom to form a one-side suction port 73H, and a branch portion 72A branching and extending from the branch portion 72A. and the other side tube portion 74 formed with the other side suction port 74H, the one side tube portion 73 and the other side tube portion 74 having a width of the accommodation portion 52A of the accommodation space 50A in a plan view of the opening portion 51A. direction inner walls 52D2, 52D3.
Therefore, the inner walls 52D2 and 52D3 facilitate positioning of the suction tube 71. As shown in FIG.

In addition, in the present embodiment, the shape retainer 65 that retains the shape of the storage portion 52A of the storage space 50A is arranged in the storage space 50A, and the suction tube 71 is arranged in the shape retainer 65 in plan view of the opening 51A. and the inner wall 52D of the accommodation space 50A.
Therefore, the shape retainer 65 and the inner wall 52D can position the suction tube 71 in the housing space 50A, and can suppress the shape retainer 65 and the suction tube 71 from collapsing the housing space 50A.

Note that the above embodiment is merely an example of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.
Although the case where the present invention is applied to the excrement processing apparatus 10 shown in FIG. 1 has been described, the structure and shape of each part may be changed as appropriate. For example, although the structure in which the suction tube 71 extends in a Y shape from the tube connection port 21A has been described, the structure is not limited to this, and the extending shape is arbitrary. For example, the suction tube 71 may have a structure in which an annular (O-shaped) tube extending along the inner wall of the housing portion 52A is connected to the branch portion 72A of the tube base portion 72 . In this case, for example, at least two or more suction ports may be provided in the middle of the annular tube at positions outside in both width directions with respect to the center line LC.

In addition, although the branch portion 72A is arranged on the base end side of the housing portion 52A (on the side of the tube connection port 21A in the longitudinal direction), the branch portion 72A is branched on the distal end side (the side away from the tube connection port 21A in the longitudinal direction). A configuration in which the portion 72A is arranged may be employed, and for example, the suction tube 71 may be T-shaped. Furthermore, the number of suction ports of the suction tube 71 is not limited to two, and may be three or more. Therefore, for example, the suction tube 71 may have a three-pronged shape extending from the tube connection port 21A.

In addition, the one-side suction port 73H and the other-side suction port 74H are arranged on the inner side in the width direction of the opening width WK of the opening 51A in a plan view of the opening 51A. 52A is larger in the width direction than the opening 51A, and the one-side suction port 73H and the other-side suction port 74H are arranged outside the opening width WK of the opening 51A in the plan view of the opening 51A in the width direction. good too.

Also, the one-side suction port 73H and the other-side suction port 74H are arranged on the front end side in the longitudinal direction of the opening 51A in a plan view of the opening 51A. The one-side suction port 73H and the other-side suction port 74H may be arranged longer than the opening 51A of the receiver 21 in the longitudinal direction.

Further, the present invention is not limited to the case of applying the present invention to the excreta disposal apparatus 10 for sucking urine, but may be applied to an excrement disposal apparatus for sucking urine, stool, menstrual blood and other excretions. .
