Description

  The present invention relates to a wearable excretion device that is not required to be replaced every time it is excreted by a sick person or a patient who needs care.

  Sick people and elderly people who cannot go to the toilet on their own due to illness, injury, or aging may use disposable diapers. However, when using a disposable diaper, it is necessary to replace it every time it is excreted, which is not only a burden for the caregiver but also hurts the user's self-esteem.

  For this reason, an excretion device shaped like a diaper that can be worn on the crotch of a human body, and an excretion device that sucks excrement accumulated inside the excretion device from the outside through a pipe has been proposed (for example, patents) Reference 1 and Patent Reference 2).

  Further, a similar wearable excretory device is also proposed in which leakage of excrement is detected by a sensor (see, for example, Patent Document 3) or cleaning power is increased (for example, see Patent Document 4). Has been.

  In addition to these, an excretion device for reducing the burden on the user or caregiver has been proposed (see, for example, Patent Document 5, Patent Document 6, and Patent Document 7).

JP-A-6-54874 JP 2005-66011 A JP-A-9-308657 JP 2004-105506 A JP 2001-190583 A JP 2002-320650 A JP 2003-144476 A

  In the conventional excretory device, excrement excreted inside the excretion device is sucked through a suction pipe or the like. At this time, the pressure for suction reaches the inside of the excretory apparatus. Since the excretory device is attached to the crotch portion of the human body, the local part, the genital region, etc. of the human body inside the excretory device are pulled by this suction. For this reason, a user receives pain and discomfort at the time of inhalation of excrement.

  On the other hand, if the suction pressure is reduced in order to reduce pain and discomfort, excrement that cannot be sucked in remains unsanitary and uncomfortable for the user and surrounding people due to odor and the like. Moreover, if excrement remains, hygiene will also worsen and the problem for a sick person and an elderly person will be large.

  Conversely, if sufficient suction pressure is applied to suck the excrement so that it does not remain inside the excretory device, the pulling pressure to the local area or the genital area will increase and the user's discomfort will be unbearable.

  As described above, in the wearable excretory device according to the prior art, the user has a problem with pain or discomfort every time the excrement is sucked. As a result, there has been a problem that makes excretion painful for sick and elderly people.

  Therefore, an object of the present invention is to provide a wearable excretory device that sucks without leaving excrement in the excretion device and does not cause pain or discomfort to the user.

  A wearable excretion device according to a first aspect of the present invention has a mounting portion that can be mounted on a crotch portion of a human body, an opening portion that is attached to the inside of the mounting portion and faces a genital area of the human body, and is excreted through the opening portion. It is characterized by comprising a receiving part for receiving an object, a shutter for opening and closing the opening, and a suction pipe connected to the receiving part for sucking excrement in the receiving part.

  The shutter covers the opening when the excrement is sucked, and normally opens the opening. Thereby, the pain and discomfort to a user are not produced at the time of inhalation of excrement. As a result, excretion can be eased for the user.

  The wearable excretory apparatus according to the second invention is characterized in that the shutter is of a slide opening type.

  When the shutter covering the opening is slid, the opening is opened, and when the shutter is slid to the original position, the opening is closed. Thus, according to the present invention, the opening can be opened and closed with a simple configuration.

  In the wearable excretory apparatus according to the third invention, the receiving part has a substantially circular cross section, the shutter is a cylindrical shape accommodated on the inner peripheral side of the receiving part, and a part of the outer periphery has an opening. It is characterized by comprising a cylindrical member cut out by substantially the same width as the width.

  When the user excretes, the excrement of the user is received by the receiving portion by arranging the cylindrical member so that the cutout portion is located at the opening. When the excrement accumulated in the receiving part is sucked, the cylindrical member is rotated to close the opening. Thus, according to the present invention, the opening can be opened and closed with a simple configuration.

  The wearable excretory apparatus according to the fourth invention further includes a water supply pipe for supplying cleaning water to the receiving part, the receiving part has a storage part for storing the shutter, and the water supply pipe can supply water to the storage part. The shutter is opened and closed by water supply from a water supply pipe.

  With this configuration, the opening can be covered with a simple configuration so as to be opened and closed. In addition, since the shutter can be opened and closed using the water pressure of the washing water supplied to the receiving part as a power source, there is no need to provide a separate power source for opening and closing the shutter, and the wearable excretory device can be downsized. Can be achieved.

  The washing water may contain an antibacterial agent. With this configuration, the inside of the wearable excretory device can be kept clean.

  The wearable excretory apparatus according to the fifth aspect of the present invention includes a partition plate that divides the opening portion into an open portion and a close portion by partially closing the opening portion, and substantially the same size as the open portion formed by the partition plate. And it is comprised by the impeller which has the same number of blade | wings as an open part.

  When the user excretes, the blades of the impeller are arranged so as to overlap the closed portion, and the open portion of the opening portion is opened. When the user excretes in this state, the excrement begins to fall from the open part to the receiving part. At this time, when the impeller is rotated, the excrement falls to the receiving portion in a state of being finely crushed by the partition plate and the impeller blades. Then, the impeller blades are arranged so as to overlap the opening portion, the opening portion is closed, and the excrement accumulated in the receiving portion is sucked in a state where the opening portion is closed. Thus, according to the present invention, not only can the partition plate and the impeller function as a shutter that opens and closes the opening, but also a crushing device that crushes excrement with a simple configuration.

  In the wearable excretory apparatus according to the sixth aspect of the invention, the receiving part has a substantially circular cross section, and the shutter is accommodated on the inner peripheral side of the receiving part, and includes a plurality of outer cylinder members having at least the width of the opening. It is characterized by comprising rotating members arranged at intervals so as to form a cylindrical shape.

  When the user performs excretion, the opening portion is opened by arranging the space portion between the two outer cylinder members so as to overlap the opening portion. When the user excretes in this state, the excrement begins to fall from the opening to the receiving part. At this time, when the rotating member is rotated, excrement falls to the receiving portion in a state of being finely crushed by the outer edge of the opening and the outer cylinder member. And an outer cylinder member is arrange | positioned so that it may overlap with an opening part, an opening part is block | closed, and the excrement accumulated in the receiving part is sucked in this state. Thus, according to the present invention, not only can the rotating member function as a shutter that opens and closes the opening, but also a crushing device that crushes excrement with a simple configuration.

  The wearable excretory apparatus according to the seventh invention further includes a blower pipe for supplying air to the receiving portion.

  With this configuration, the user's buttocks and genital area can be appropriately dried, and uncomfortable feelings such as stuffiness due to wearing of the wearable excretory device can be reduced.

The receiving part is preferably subjected to antibacterial treatment.
With this configuration, the sanitary condition of the receiving part can be enhanced.

The wearable excretory apparatus according to the eighth invention is characterized in that the receiving part further includes a light source for irradiating the light guide tube and the light guide tube, and the inside of the receiving part is subjected to photocatalytic treatment.
With this configuration, the light guide tube is turned on by the light source to irradiate the inside of the receiving portion, and thereby the sanitary condition inside the receiving portion can be enhanced by the photocatalytic action performed inside the receiving portion.

  Moreover, it is good for the mounting part of the said mounting | wearing type excretion apparatus to further provide the opening | mouth with which a human body leg can be inserted or removed. With this configuration, the user can easily wear the wearable excretory device.

  The wearable excretion apparatus according to the ninth invention is characterized by further comprising an air mat outside the wearing portion. With this configuration, even when the user wearing the wearable excretory device is bedridden, the posture can be appropriately maintained.

  The wearable excretion apparatus according to a tenth aspect of the present invention further includes a suction unit that applies a suction pressure to the suction pipe. With this configuration, excrement can be easily sucked.

  According to the present invention, even a person who is difficult to excrete alone, such as a sick person or an elderly person, can excrete while lying down. Furthermore, the excreted excreted material is reliably discharged from the wearable excretory device.

  In addition, when the excrement accumulated in the receiving part is aspirated, the shutter covers the opening when the excrement is aspirated, so that the suction pressure does not reach the user's genital area and so on. I don't feel it. For this reason, the excretion act for a user becomes easy. For this reason, the burden of care is reduced and it is useful also for a user's independence support.

  Further, since the shutter of the receiving part is closed while the excrement is accumulated in the receiving part, there is no odor leakage and there is little discomfort for the user and the surrounding people.

  Furthermore, since the shutter of the receiving portion is closed when the excrement is sucked, the excrement is hardly scattered and the inside of the wearable excretory device is kept clean. As a result, the replacement period of the wearable excretory device becomes longer, and the use cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
First, the configuration of the wearable excretory apparatus will be described with reference to FIGS.

  FIG. 1 is a perspective view of a wearable excretion apparatus according to Embodiment 1 of the present invention. FIG. 2 is a side view of the wearable excretion apparatus according to Embodiment 1 of the present invention.

  The wearable excretory device 1 is provided with a wearable part 2 that can be worn on the crotch of a human body.

  The mounting portion 2 has an opening 3 and an opening 5, and the opening 3 passes the waist of the human body at the time of mounting, and the opening 5 passes the leg of the human body at the time of mounting. The band 4 fixes the human body and the wearing part 2 when worn. That is, the user wears the wearable excretory device 1 so as to wear the pants through the foot from the opening 5.

  The mounting portion 2 is made of a safe material that does not cause inflammation or allergic reaction even when touched by a human body, and is made of a waterproof and breathable fabric. In order to prevent odor leakage, it is also preferable to cover the outside with a material such as nylon or vinyl. Moreover, it is also preferable that the opening 3 and the opening 5 have a gather shape so as to fit the crotch portion, and the portion of the mounting portion 2 that touches the human body is soft and the outside is formed of a hard material. It is also suitable. When the wearable excretory device 1 is worn on the human body, the wearer 2 fits the human body appropriately.

  A receiving portion 9 for receiving excrement is provided inside the mounting portion 2. The receiving part 9 is provided at the bottom of the mounting part 2. Moreover, the mounting part 2 has the opening part 10 (refer FIG. 5), and when the mounting | wearing type excretion apparatus 1 is mounted | worn with a human body, the opening part 10 is a local part (position of an excretory organ) of a human body. The receiving portion 9 is provided inside the mounting portion 2 so as to face the position. The receiving part 9 receives excrement through the opening 10 and accumulates excrement inside the receiving part 9. It is also preferable that the receiving part 9 includes a concave shape such as a dish so that excrement can be easily collected. Furthermore, the inside of the receiving part 9 is also preferably subjected to antibacterial treatment.

  Moreover, it is also suitable from a hygiene side that a ventilation pipe is connected to the receiving part 9 and air is blown into the receiving part 9 inside. Moreover, a shadow part can also be dried with the ventilation by a ventilation pipe.

  Moreover, the receiving part 9 may be provided with a light guide tube and a light source for irradiating light to the light guide tube. When the photocatalyst treatment is performed inside the receiving portion 9, an antibacterial effect and a bactericidal effect are obtained by light such as ultraviolet rays through the light guide tube. Since the excrement touches the receiving part 9 directly, it is preferable that the process which raises such a sanitary effect is made | formed.

  Furthermore, a shutter 11 that covers the opening 10 of the receiving portion 9 is provided. The shutter 11 can be opened and closed, and can be closed to cover the opening 10 or can be opened to open the opening 10.

  The suction pipe 6 is connected to the receiving part 9, sucks the excrement accumulated in the receiving part 9, and discharges the excrement to the outside of the wearable excretory device 1. The suction pipe 6 is connected to the receiving portion 9 and then protrudes from the tip of the wearable excretory device 1 (near the shadow when the human body is worn) to be connected to the suction device 12. The suction device 12 applies a suction pressure to the suction pipe 6. The suction device 12 applies a suction pressure by having a pump function and a vacuum function.

  The water supply pipe 7 supplies water to the inside of the receiving part 9 and the opening / closing mechanism of the shutter 11. By supplying water to the receiving part 9, excrement accumulated in the receiving part 9 becomes soft and is easily excreted from the suction pipe 6, and the receiving part 9 can be cleaned. For this reason, it is also suitable from the surface of the washing | cleaning effect that the water supplied from the water supply pipe 7 contains the washing | cleaning component.

  The drainage pipe 8 drains the water used for the opening / closing mechanism of the shutter 11 from the water supplied from the water supply pipe 7. In addition, the water supplied to the receiving part 9 is drained to the suction device 12 through the suction pipe 6 together with the excrement.

  The wearable excretory apparatus 1 may be formed as an integral type as shown in FIGS. 1 and 2, or may be formed as a separated type as shown in FIG. 3.

  FIG. 3 is a perspective view of the wearable excretory apparatus according to Embodiment 1 of the present invention. In the wearable excretion apparatus 1 shown in FIG. 3, the wearing part 2 and the functional part 13 can be separated. The functional part 13 is a part including the receiving part 9 for receiving excrement and the suction pipe 6 in the wearable excretory apparatus 1. On the other hand, the mounting part 2 is a part for attaching the mounting type excretory apparatus 1 to a human body. That is, the functional unit 13 has a function of actually receiving excrement from the human body and discharging the excrement, but the mounting unit 2 has a function of attaching to the human body.

  For this reason, in the wearable excretion apparatus 1, the functional unit 13 is mainly subjected to dirt due to excrement, and the attachment part 2 is not likely to receive dirt due to excrement. In the case of the separation type as shown in FIG. 3, only the functional unit 13 that is easily contaminated can be replaced, so that the usage cost of the wearable excretory device 1 can be reduced.

  Moreover, since the mounting part 2 has a mounting function to the human body, it is preferable that the mounting part 2 is made of a soft and comfortable material, and the functional part 13 has an excretion function. Is preferably made of a material having high strength. The function unit 13 and the mounting unit 2 may be connected by a button, a zipper, or the like.

  In addition to the separation of the functional unit 13, the suction pipe 6, the water supply pipe 7, and the drainage pipe 8 may be individually separable. This is because it is possible to appropriately change from a heavily contaminated member, and the use cost of the wearable excretory device 1 is further reduced.

  FIG. 4 shows the separated functional unit 13. FIG. 4 is a perspective view of a functional unit according to Embodiment 1 of the present invention. The wearable excretory device 1 is also preferably sold as a set of the wearing part 2 and a replacement functional part 13.

  As shown in FIGS. 1 and 2, when formed integrally, the functional unit 13 having the excretion function does not come off even if the user moves violently or turns over. So it is effective in maintaining hygiene. Moreover, since the whole mounting | wearing type excretion apparatus 1 is replaced, an inexpensive material can be used and it can utilize as a spread product.

  Next, use of the wearable excretory apparatus 1 will be described.

  FIG. 5 is an explanatory diagram for explaining the usage state of the wearable excretory apparatus according to Embodiment 1 of the present invention. The wearable excretory device 1 is worn on the crotch portion of the human body 15. The wearable excretory device 1 is fixed to the human body 15 by the band 4. Since the wearable excretory device 1 is worn on the crotch, the foot 16 of the human body 15 protrudes.

  When attached to the human body 15, the receiving portion 9 is positioned so as to face the pubic area which is an excretory organ. The upper surface of the receiving portion 9 and the plane facing the shadow portion has an opening 10, and the shutter 11 can open and close the opening 10. FIG. 5 shows a state where the shutter 11 is closed. A suction pipe 6 is connected to the tip of the receiving portion 9.

  When attached to a human body, the shutter 11 is normally in an open state. The user excretes excretion in the receiving part 9 during excretion. Since the shutter 11 is open, excrement accumulates in the receiving part 9. Further, washing water is sprayed from the spray nozzle 14 to the genital area as necessary, and the genital area after excretion is cleaned. Washing water is supplied to the injection nozzle 14 from the water supply pipe 7. The washing water that has washed the genital area collects in the receiving part 9 together with the excrement. At this time, it is preferable that the inside of the wearable excretory device 1 has an appropriate curve so that the washing water can easily collect in the receiving portion 9. Moreover, it is also suitable from a hygiene aspect that the wash water contains an antibacterial agent.

  When excretion is completed, the shutter 11 is closed, and the receiving part 9 and the shadow of the human body 15 are isolated by the closed shutter 11.

  When the shutter 11 is closed, a suction pressure is applied to the suction pipe 6 from a suction device 12 (not shown in FIG. 5) functioning as a suction unit. The excrement accumulated in the receiving portion 9 is sucked together with the washing water by this suction pressure and discharged through the suction pipe 6. At this time, since the excrement is softened by the wash water supplied from the water supply pipe 7 and jetted from the jet nozzle 14, suction is easy. Or even when the injection nozzle 14 is not provided, the water is supplied from the water supply pipe 7 to the receiving portion 9, so that the excrement is similarly softened and the suction becomes easy.

  Thus, normally, the shutter 11 is open, and the excrement accumulates in the receiving part 9 because the receiving part 9 is opened. Since the shutter 11 is closed when the excrement accumulated in the receiving part 9 is sucked from the suction pipe 6, the suction pressure applied to the receiving part 9 from the suction pipe 6 does not reach the shadow of the human body 15. For this reason, unlike the conventional wearable excretory device, the user can comfortably perform excretion without causing discomfort or pain due to the pressure applied during excretion of the excrement.

  Conventionally, since the pain and discomfort that have been felt each time of excretion do not occur, the user is less likely to avoid excretion, and constipation and poor excretion are also reduced. In addition, when excrement is aspirated from the suction pipe 6, the wearable excretory device 1 may be provided with a valve-equipped air vent connected to the receiving part 9 in order to prevent a decrease in the atmospheric pressure of the receiving part 9. . For example, a blower pipe corresponding to the suction pipe 6 is provided, and air is supplied from the blower pipe to the receiving portion 9 during suction by the suction pipe 6. This inflating with the valve can prevent the excrement from being sucked smoothly due to a drop in the atmospheric pressure in the receiving part 9 when the excrement is aspirated. It is desirable that the valve-equipped air inlet is provided in a portion as far as possible from the shadow of the human body 15. Moreover, it is good also as a structure which forms the mounting | wearing part 2 or the function part 13 with a material with sufficient air permeability, and external air is attracted | sucked through them instead of providing the air with a valve.

  As described above, according to the wearable excretion device 1 of the present invention, a user who is difficult to perform an independent excretion can perform an excretion without any other person's care without feeling uncomfortable or painful. .

(Embodiment 2)
Next, a second embodiment will be described. In the second embodiment, various variations of the shape of the receiving portion 9 and the opening / closing mechanism of the shutter 11 will be described. Various forms of the shape of the receiving portion 9 and the opening / closing mechanism of the shutter 11 are appropriately selected.

  6, FIG. 7, FIG. 8, FIG. 9, and FIG. 10 are cross-sectional views of the receiving portion and the peripheral portion in the second embodiment of the present invention.

  First, it demonstrates using FIG. The wearable excretory device 1 is worn on a human body and is worn with the buttocks 20 closely attached. Since it is attached to the heel part 20, the receiving part 9 is located opposite to the pubic part which is an excretory organ. The receiving part 9 shown in FIG. 6 has a cross-sectional shape close to an ellipse. Since the cross section of the receiving portion 9 is elliptical, the amount of protrusion below the heel portion 20 is small, and even when the user is sleeping, there is little lifting of the body, and there is little discomfort due to wearing . Moreover, by being elliptical shape, the area of the opening part 10 can be taken widely with respect to the capacity | capacitance of the receiving part 9, and the receiving part 9 tends to receive excrement.

  The shutter 11 allows the opening 10 to be opened and closed. The shutter 11 is composed of two slide-opening members 17, and when opening, the members 17 are stored in the storage portion 18. The water supply pipe 7 is connected to the storage portion 18, and when water is supplied to the storage portion 18, the member 17 slides toward the opening portion 10 with this water pressure, and the shutter 11 closes the opening portion 10. On the other hand, when drained from the storage unit 18, the water pressure in the storage unit 18 is lost, the members 17 are stored in the storage unit 18, and the shutter 11 opens the opening 10.

  As described above, the shutter 11 using the two members 17 is opened and closed by water supply and drainage through the water supply pipe 7, thereby realizing an opening / closing mechanism with a simple configuration. Since the water supply pipe 7 can also serve as the water supply to the receiving part 9 and the injection nozzle 14, an opening / closing mechanism is realized with few constituent requirements.

  Further, the receiving portion 9 and the opening / closing mechanism may be as shown in FIG. The cross-sectional shape of the receiving part 9 in FIG. 7 is circular. In the case of a circular shape, the protruding amount of the flange portion 20 is increased. However, since the member 17 forming the shutter 11 can be accommodated along the outer edge of the receiving portion 9, the receiving portion 9 can be manufactured. It becomes easy.

  The opening / closing mechanism of the shutter 11 in FIG. The pulley 19 slides the member 17 along the outer edge of the receiving portion 9. A storage portion 18 for storing the member 17 is provided on the outer edge of the receiving portion 9, and the member 17 stored in the storage portion 18 is pulled out of the storage portion 18 by the rotation of the pulley 19. The drawn member 17 covers the opening 10, and the shutter 11 closes the opening 10.

  When the pulley 19 rotates in the reverse direction, the drawn member 17 is slid toward the storage unit 18, and the member 17 is stored in the storage unit 18. When the member 17 is stored in the storage unit 18, the shutter 11 opens the opening 10.

  The water supply pipe 7 supplies water to the injection nozzle 14.

  Next, a description will be given with reference to FIG. The receiving portion 9 shown in FIG. 8 has a rounded square cross-sectional shape. Compared to the elliptical shape shown in FIG. 6, the shape is further crushed in the vertical direction, and the opening 10 is widened, and the amount of protrusion below the flange 20 is reduced, so that there is little uncomfortable feeling at the time of wearing.

  The shutter 11 is composed of two members 17, and each of the members 17 is stored in a storage portion 18. The storage unit 18 is provided not in the outer edge of the receiving unit 9 but in the wearable excretory device 1.

  As in the case of FIG. 7, the member 17 is slid by the pulley 19. The rotation surface of the pulley 19 is in contact with the member 17, and the rotation of the pulley 19 is transmitted to the member 17 so that the member 17 slides. When the pulley 19 rotates in one direction, this rotational force is transmitted, and the member 17 is pulled out from the storage portion 18. Since the member 17 is pulled out from the left and right of the opening 10, the opening 10 is closed when the tips of the two members 17 are in contact with each other. That is, the shutter 11 closes the receiving portion 9.

  When the pulley 19 rotates in the direction opposite to the above, the rotational force is transmitted to the member 17 and the drawn member 17 slides toward the storage portion 18. The two members 17 are respectively stored in the storage portion 18 and the opening 10 is opened.

  With the opening / closing mechanism of the shutter 11 as shown in FIG. 8, the receiving portion 9 is formed into a flat square shape, and the opening / closing by the shutter 11 is realized. Therefore, the wearable excretory device 1 that is easy to use is realized. .

  Further, as shown in FIG. 9, the opening and closing of the shutter 11 may be realized by sliding the member 17 using the motor 21 instead of the pulley 19.

  Further, as shown in FIG. 9, the shutter 11 may be opened and closed in an arc shape along the curve of the collar portion 20, but may be opened and closed in an opposite arc shape as shown in FIG. In the case of the shutter 11 shown in FIG. 10, the capacity of the receiving part 9 is increased, and the receiving part 9 can easily collect excreta.

  Further, the shutter 11 may be configured as shown in FIG. As shown in FIG. 11, the shutter 11 includes a partition plate 61 and an impeller 64. As shown in FIG. 11A, the partition plate 61 and the impeller 64 are provided in the receiving portion 9 and prevent the shadow of the human body 15 from directly touching the impeller 64. The partition plate 61 divides the opening 10 into an opening 62 (see FIG. 13) and a closing 63 (see FIG. 13) by partially closing the opening 10. Further, the impeller 64 has substantially the same size as the open portion 62 formed by the partition plate 61 and has the same number of blades 65 as the open portion 62.

  As shown in FIG. 11, the partition plate 61 has an outer shape that is substantially the same size as the circular opening 10 in plan view, and can be detachably fitted into the opening 10. The partition plate 61 is provided with fan-shaped openings 611 of the same size at equal intervals.

  The impeller 64 is detachably attached to the upper side of the partition plate 61 and coaxially with the center of the partition plate 61, and water pressure by water supplied from the water supply pipe 7 or air pressure sent from a blower pipe (not shown). The motor can be rotated by power such as a motor (not shown). The blades 65 of the impeller 64 are formed in a size capable of closing the opening 611 of the partition plate 61 and are arranged at equal intervals. Further, as shown in FIG. 11A, the blades 65 are attached so as to be inclined by about 10 degrees as a whole.

  When the user excretes, as shown in FIG. 13A, the opening 10 is arranged in a plan view so that the blade 65 does not overlap the opening 611. Thereby, the open part 62 will be in an open state, and a user's excrement will fall from this open part 62 to the receiving part 9. FIG. When the user performs excretion, if the impeller 64 is rotated by a power source (not shown), the excrement can be finely crushed by the blade 65 and the edge of the opening 611 of the partition plate 61. Further, since the blades 65 are inclined by about 10 degrees, excrement can be more efficiently crushed.

  When the crushed excrement accumulated in the receiving part 9 is sucked, the blades 65 of the impeller 64 are arranged so as to overlap the openings 611 of the partition plate 61 as shown in FIG. Thereby, the open part 62 is closed by the blades 65, and all the openings 10 are closed. In this state, by applying suction pressure by the suction device 12 and performing suction, the suction pressure does not reach the user, so that the user does not feel uncomfortable. Further, since the excrement has already been finely crushed by the impeller 64, the excrement accumulated in the receiving portion 9 can be quickly and reliably aspirated.

  In the shutter 11 shown in FIGS. 11 and 12, the partition plate 61 having four openings 611 and the impeller 64 formed by four blades 65 are used. It is not limited to form.

  Moreover, the shape of the partition plate 61 and the impeller 64 may be as shown in FIG. As shown in FIG. 12, the partition plate 66 and the blades 68 of the impeller 67 are formed in a shape simulating a petal that curves downward, and are attached to a position that descends from the opening 10 to the back side of the receiving portion 9. ing. Since the blades 68 are shaped like petals curved downward, the blades 68 can easily hold excrement, and even if the impeller 67 rotates, the crushed excrement may jump out of the opening 10. Therefore, the vicinity of the user's genital area can be kept clean. In addition, since the partition plate 66 and the impeller 67 are attached at positions where the partition plate 66 and the impeller 67 are lowered from the opening 10 to the back side of the receiving portion 9, it is possible to prevent the impeller 67 from hitting the shadow of the user. In this case, it is preferable that the partition plate 66 is attached to the receiving portion 9 via an urging means (not shown) for urging the impeller 67 side. Thereby, the adhesiveness of the partition plate 66 and the impeller 67 can be improved, and the discomfort with respect to the user at the time of attraction | suction, an odor leak, etc. can be prevented.

  Further, the shutter 11 may be configured as shown in FIGS. As shown in FIGS. 14 and 15, the shutter 11 includes a socket 70 housed on the inner peripheral side of the receiving portion 9, and a plurality of shutters 11 housed in the socket 70 and having at least the width of the opening 10 (T in FIG. 14). The outer cylinder member 72 is constituted by a rotating member 71 arranged at an interval so as to form a substantially cylindrical shape.

  A part of the outer cylinder is notched in the socket 70 by the same width T as the opening 10, and the notched part is disposed so as to face the opening 10. In addition, a discharge opening 701 is formed so as to be coupled to one end of the suction pipe 6 connected to the receiving portion 9 when stored in the receiving portion 9.

  The rotating member 71 is a rotating body in which two outer cylinder members 72 are connected to each other by a connecting member 73 with a gap therebetween, and is inserted into the socket 70 so as to be freely inserted and removed. The connecting member 73 is configured by an urging member such as a spring, and the outer cylinder member 72 is always urged outward in the radial direction by the urging member. The rotating member 71 rotates along the inner periphery of the socket 70 by water pressure supplied from the water supply pipe 7, air pressure sent from a blower pipe (not shown), and power such as a motor (not shown). It is possible.

  When the user performs excretion, the outer cylinder member 72 is disposed so as not to overlap the opening 10. Thereby, since the opening part 10 is an open state, a user's excrement will fall to the receiving part 9 through the socket 70 from the opening part 10. FIG. When the user performs excretion, if the rotating member 71 is rotated by a power source (not shown), the excrement can be finely crushed by the outer cylinder member 72 and the edge 702 facing the opening 10 of the socket 70. it can.

  Here, since the outer cylinder member 72 of the rotating member 71 is urged toward the socket 70 by the urging member of the connecting member 73, an extra gap is created between the rotating member 71 and the socket 70. Therefore, it is possible to prevent excrement from accumulating between the rotating member 71 and the socket 70 and causing the rotating member 71 to rotate poorly.

  When the crushed excrement accumulated in the receiving part 9 is sucked, the outer cylinder member 72 is rotated so as to close the opening 10. In this state, by applying suction pressure by the suction device 12 and performing suction, the suction pressure does not reach the user, so that the user does not feel uncomfortable. Moreover, since the excrement has already been finely crushed by the rotating member 71, the excrement accumulated in the receiving portion 9 can be quickly and reliably aspirated.

  In the shutter 11 shown in FIGS. 14 and 15, the rotating member 71 connecting the two outer cylinder members 72 is used. However, the number of the outer cylinder members 72 is not limited to the above embodiment. A rotating member in which three or more outer cylinder members are connected may be used as long as the opening 10 can be closed and the openings 10 can be connected at an interval enough to open the openings 10.

  In the shutter 11 shown in FIGS. 14 and 15, since the opening / closing mechanism of the shutter 11 can be realized by rotating the rotating member 71 in the same direction, like the mechanism of the shutter 11 shown in FIGS. It is not necessary to provide two pulleys 19 and two motors 21 for opening and closing 11, and the mechanism of the shutter 11 can be realized with a simpler configuration.

  Thus, according to the mechanism of the shutter 11 constituted by the partition plate 61 and the impeller 64 and the mechanism of the shutter 11 constituted by the rotating member 71, the shutter 11 that opens and closes the opening portion 10 with a simple configuration. Two functions of a crushing device for crushing excrement can be provided. In addition, by providing a mechanism of the shutter 11 capable of crushing such excrement, it becomes easy to suck excrement by the suction device 12, so that the suction device 12 can be moved with small power, It is possible to reduce the size of the suction device 12 and to reduce the power cost for operating the suction device 12.

  As shown in FIGS. 6 to 10 and 14, a cushioning material 30 may be provided between the heel part 20 and the wearable excretory apparatus 1. The cushioning material 30 relieves the feeling of pressure on the collar part 20 and extends the distance between the shutter 11 and the receiving part 9 and the collar part 20 (and the shadow part). For this reason, it is possible to prevent the excrement from adhering to the buttocks 20, and to further reduce discomfort during the excretion of the excrement.

  As described above, the opening / closing mechanism of the shutter 11 described with reference to FIGS. 6 to 15 can easily and reliably realize the opening / closing of the receiving portion 9 with respect to the opening 10. By opening and closing the shutter 11, the shutter 11 is normally opened and excrement accumulates in the receiving portion 9. Since the shutter 11 is closed when the excrement is aspirated, the user does not feel discomfort or pain due to the aspiration.

  Moreover, excrement accumulates in the receiving part 9, and the accumulated excrement is discharged | emitted through the suction pipe 6, The interior of the mounting | wearing type excretion apparatus 1 is kept clean. In particular, since the shutter 11 is closed at the time of suction, the excrement is not scattered outside the receiving portion 9. Moreover, since the shutter 11 closes when the excrement collects in the receiving part 9, there is little leakage of odor and the discomfort to the user and the surrounding people is also reduced. The shutter 11 may be composed of two members or a single member. Further, when the cross section of the receiving portion 9 is circular, the shutter 11 may be accommodated in the accommodating portion 18 along the circular outer periphery. Even when the cross section of the receiving portion 9 is elliptical or rectangular, the shutter 11 may be accommodated in the accommodating portion 18 along the outer periphery thereof. Various shapes are selected as the shape of the receiving portion 9. Various shapes and methods may be selected as the shape of the shutter 11 and the storage method.

  The shutter 11 may be opened and closed by a user operating a switch or the like, and a sensor is provided in the receiving portion 9, and if it is detected that excrement has accumulated, The opening / closing operation may be performed automatically. The sensor that senses that the excrement has accumulated is realized by an odor sensor or an infrared sensor.

  The wearable excretory device 1 may include an air mat 40 outside as shown in FIG. FIG. 16 is a perspective view of a wearable excretion apparatus according to Embodiment 2 of the present invention.

  The air mat 40 is a member simulating the shape of a wing provided outside the mounting portion 2 and swells when air is fed.
