Description

  The present invention relates to a wearable excretion device that is attached to a human body such as a sick person or a patient who needs care and receives excrement.

  Due to illness, injury, aging, etc., sick and elderly people who cannot go to the toilet by themselves may use disposable diapers. However, when a disposable diaper is used, it must be replaced 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 has been developed, and an excretion device that sucks excrement accumulated inside the excretion device from the outside through a pipe has been proposed ( For example, see Patent Documents 1 to 3.)

  However, in the case of a conventional suction-type excretion device, excrement that has fallen to the suction inlet of the pipe can be successfully sucked and taken in, but excrement that has fallen to a place away from the suction intake of the pipe There is a problem that suction is not possible. This problem cannot be solved even if the output of the suction device is increased, and will eventually be removed manually.

  Therefore, an object of the present invention is to provide a wearable excretion device that can discharge without leaving excrement inside the excretion device.

  The wearable excretory device of the present invention sucks excrement through an attachment part that can be attached to a crotch part of a human body, a receiving part that receives excrement facing the genital part of the human body, and an opening connected to the receiving part. The suction pipe is provided with a piston that covers the opening and slides out excrement by sliding in the suction pipe.

  According to the wearable excretory device of the present invention, when the excrement attached to the crotch part of the human body and received by the receiving part is sucked by the suction pipe through the opening connected to the receiving part, the sliding operation of the piston When the opening is covered by the above, the space between the suction pipe and the receiving part is hermetically sealed. Thereby, if the inside of this suction pipe is sucked, the waste in the suction pipe can be completely removed.

  Further, the wearable excretory device of the present invention comprises a valve mechanism at the front end of the piston that brings the front space and rear space of the piston into communication when the piston covers the opening, and the rear space of the piston. However, it is desirable that it is open to the atmosphere. Accordingly, when the opening is covered by the advance of the piston, the front space of the piston and the rear space opened to the atmosphere are in communication with each other. Therefore, when the excrement is sucked from the suction pipe, the rear space of the piston The air is drawn from the air, and the excrement can be sucked with the air with a light suction force.

  The valve mechanism includes a piston body having a communication hole that communicates the front space and the rear space of the piston, a valve that opens and closes the communication hole by moving forward and backward in front of the piston body, and the valve closes the communication hole. It is desirable to be composed of a spring urging in the direction and a piston stopper that prevents the piston body from moving forward after the piston body covers the opening and advances only the valve.

  Normally, the valve closes the communication hole by the biasing force of the spring. However, after the piston main body moves forward and covers the opening, the piston stopper prevents the piston from moving forward, so that only the valve moves forward. As a result, the front space and the rear space of the piston are in communication with each other, and when the excrement is sucked from the suction pipe, air is drawn from the rear space of the piston, and the excrement is sucked together with this air with a light suction force. Is possible.

  The wearable excretory device of the present invention preferably includes a sliding plate that slides along the inner surface of the receiving portion to guide the excrement in the receiving portion to the opening.

  As a result, when the excrement attached to the crotch part of the human body and received by the receiving part is sucked by the suction pipe through the opening connected to the receiving part, the sliding plate slides along the inner surface of the receiving part. The excrement in the receiving part can be guided to the opening and sucked and taken in by the suction pipe.

  Here, it is desirable that the sliding plate slides while jetting water or air. Accordingly, when the excrement in the receiving part is guided to the opening by sliding of the sliding plate, the excrement in the receiving part can be removed by water or air sprayed from the sliding plate, and excretion in the receiving part. Things can be removed neatly. In particular, in the case of water jetting, the effect of rinsing in the receiving part can be obtained, so that excrement in the receiving part can be removed more neatly.

  The sliding plate is preferably made of an elastic material. Because the sliding plate is made of an elastic material, when sliding along the inner surface of the receiving portion, the sliding plate bends and slides in close contact with the inner surface of the receiving portion, so that it adheres to the inner surface of the receiving portion. It is possible to remove all the excrement left.

  Further, the wearable excretory apparatus of the present invention includes a piston in which a sliding plate is connected to a piston rod, a cylinder in which the piston is housed via a spring, water or air is introduced into the cylinder, and the piston is pushed out. It is desirable to have a pressure feeding mechanism. Thereby, the sliding plate can be advanced together with the piston by introducing water or air into the cylinder by the pressure feeding mechanism. Further, the sliding plate can be moved back together with the piston by the reaction force of the spring compressed or extended by the advance of the piston.

  The sliding plate is provided with an injection port for injecting water or air, and the piston and the piston rod are provided with a conduction hole for guiding water or air introduced into the cylinder to the injection port of the sliding plate. It is desirable that Thus, when water or air is introduced into the cylinder by the pressure feeding mechanism, the introduced water or air is ejected from the ejection port of the sliding plate through the conduction hole of the piston and the piston rod, and is ejected from the sliding plate. The excrement in the receiving part can be removed by air or water, and the excrement in the receiving part can be removed cleanly.

  In addition, the wearable excretory device of the present invention preferably includes a shutter that covers the opening so as to be opened and closed. Thereby, when sucking with the suction pipe, by closing the shutter, it is possible to prevent the user's local area, shadow, or the like from being pulled in, and to prevent pain or discomfort.

FIG. 5, FIG. 5 is an enlarged plan view of the suction part of FIG. 1, FIG. 6 is a cross-sectional view taken along line AA of FIG. 5, FIG. 7 is a perspective view of the wearable excretory device of FIG. FIG. 9 is a plan view showing the operation of the sliding plate, and FIGS. 10 to 13 are side sectional views showing the operation of the piston in the suction pipe. In the following, for the sake of convenience, the left side of FIG. 2 will be described as the front and the right side as the rear.

  Referring to FIG. 1, a wearable excretory apparatus 1 according to an embodiment of the present invention includes a device main body 2 attached to a crotch portion of a human body B, a compressor 3 connected to the device main body 2 for supplying high-pressure air, and a device main body. 2, a water pump 4 for supplying high-pressure water and a suction device 5 connected to the apparatus main body 2 for sucking excrement. In addition, in the example of illustration, although the compressor 3, the water pump 4, and the suction device 5 are shown separately, these may be formed integrally.

  As shown in FIGS. 2 and 3, the apparatus main body 2 is connected to the mounting portion 10 that can be attached to the crotch portion of the human body B, the receiving portion 11 that receives the excrement facing the shadow of the human body B, and the receiving portion 11. A suction pipe 13 for sucking excrement through the opening 12, a guide part 14 formed at the lip of the opening 12 of the suction pipe 13, for guiding excrement in the receiving part 11 to the opening 12, and suction A piston 15 that slides in the pipe 13, an air cylinder 16 that moves the piston 15 forward and backward, and a sliding plate 17 that slides along the inner surface of the receiving portion 11 are provided.

  The mounting portion 10 is made of a safe material that does not cause inflammation or an allergic reaction even when touched by the human body B, and is made of a waterproof and breathable fabric. In order to prevent odor leakage, the outside can be covered with a material such as nylon or vinyl. Moreover, since the apparatus main body 2 is mounted on the human body B so as to straddle the mounting section 10, the mounting section 10 is formed of a soft material at the portion touching the human body and fitted with a hard material on the outside so as to fit the crotch. It is also possible to do.

  The receiving part 11 is provided inside the mounting part 10. The guide part 14 is connected to the bottom part of the receiving part 11 so as to be a position facing the local part (position of the excretory organ) of the human body when the apparatus main body 2 is attached to the human body. The guide part 14 receives excrement through the receiving part 11 and accumulates excrement inside the guide part 14. The guide portion 14 has a hemispherical shape in the present embodiment, but may have any shape that can easily collect excreta.

  As shown in FIG. 5, the suction pipe 13 includes a straight cylindrical cylinder part 13 a in which the piston 15 is housed and reciprocates, and excrement that is connected to the cylinder part 13 a and pushed out from the cylinder part 13 a. It comprises a discharge portion 13b that leads to a discharge port 19 formed in a terminal member 18 at the rear of the main body 2. The rear space of the cylinder portion 13a is open to the atmosphere through a filter 20 (see FIG. 4) that penetrates the end member 18 and has a plurality of through holes 20a.

  The suction device 5 shown in FIG. 1 is connected to the discharge port 19. The suction device 5 has a pump function and a vacuum function, and applies a suction pressure to the suction pipe 13. The termination member 18 is provided with air inlets 21a and 21b to which the compressor 3 is connected via a solenoid valve (not shown). The air inlet / outlet ports 21a and 21b are connected to both ends of the air cylinder 16, respectively, and the flow path of high-pressure air supplied by the compressor 3 is controlled to one of the air inlet / outlet ports 21a and 21b. This is for reciprocating a piston (not shown). The piston rod 16a connected to the piston is connected to the piston 15 by a connecting member 16b.

  The piston 15 includes a piston body 15a, a valve 15b, a spring 15c that urges the piston body 15a toward the valve 15b, a rod 15d connected to the valve 15b, and the like. The piston body 15a is formed with a communication hole 15e that allows the front space and the rear space of the piston 15 to communicate with each other. The valve 15b opens and closes the communication hole 15e by moving forward and backward in front of the piston body 15a. Since the spring 15c biases the piston body 15a toward the valve 15b, the valve 15b normally closes the communication hole 15e. The connecting member 16b of the air cylinder 16 is connected to the rod 15d through a groove 13c formed in the cylinder portion 13a.

  The sliding plate 17 is formed in a shape along the inner surface of the receiving portion 11, for example, a substantially meniscus shape, so as to slide in close contact with the inner surface of the receiving portion 11. In the present embodiment, the sliding plate 17 is formed of a flexible elastic material such as silicon rubber. Piston rods 32 of a piston 31 housed in a cylinder 30 via springs 33 are connected to both ends of the sliding plate 17. Further, a hose 34 to which the water pump 4 is connected is connected to the cylinder 30 via a solenoid valve (not shown).

  By introducing high-pressure water into the cylinder 30 through the hose 34 and pushing out the piston 31, the sliding plate 17 advances as shown in FIGS. 8B and 9B. Further, the sliding plate 17 is retracted by the reaction force of the spring 33 compressed by the extrusion of the piston 31, and the sliding plate 17 returns to the original position shown in FIGS. 8 (a) and 9 (a). And return. By repeating such an operation by controlling the electromagnetic valve, the sliding plate 17 is slid along the inner surface of the receiving portion 11, and excrement in the receiving portion 11 is passed through the guide portion 14 to the opening portion 12. Lead.

  In addition, a plurality of injection ports 17 a for injecting water are provided on the lower surface of the sliding plate 17. Inside the sliding plate 17, a conduction hole 17 b that guides water to each injection port 17 a is formed. The piston 31 and the piston rod 32 are also formed with a conduction hole 32a communicating with the conduction hole 17b. The conduction hole 32 a is connected to the side through which the high-pressure water is introduced by the hose 34 of the cylinder 30 through the piston 31. Therefore, when high-pressure water is introduced into the cylinder 30 through the hose 34 as described above, the high-pressure water is injected from the injection ports 17a through the conduction holes 32a and 17b.

  The water pump 4 is connected to the water inlet 22 of the termination member 18. The high-pressure water introduced into the water inlet 22 by the water pump 4 is supplied to the inside of the receiving part 11 in addition to the hose 34 described above. By supplying water to the receiving part 11, excrement accumulated in the receiving part 11 becomes soft and is easily excreted by the suction pipe 13. Moreover, the receiving part 11 can also be cleaned. For this reason, if the water supplied from the water pump 4 contains a cleaning component, the cleaning effect is enhanced.

Next, operation | movement of the mounting | wearing type excretion apparatus 1 of the said structure is demonstrated.
The apparatus main body 2 is attached to the crotch portion of the human body B. When the apparatus main body 2 is attached to the human body B, the guide part 14 is positioned so as to face the genital part that is an excretory organ. At this time, as shown in FIG. 11, the piston 15 is positioned behind the cylinder portion 13a, and the opening 12 of the cylinder portion 13a is open. The excrement is normally excreted by the guide part 14 and falls into the cylinder part 13 a from the opening part 12, but may be excreted from the guide part 14 and excreted into the receiving part 11. Here, by operating the water pump 4 and supplying water into the receiving portion 11, the inside of the receiving portion 11 is washed and excrement flows into the guide portion 14.

  Further, by introducing high pressure water into the cylinder 30 through the hose 34 by the water pump 4 and pushing out the piston 31, as shown in FIGS. 8 and 9, high pressure water is supplied from the injection port 17a while the sliding plate 17 is advanced. Let spray. As a result, the excrement in the receiving portion 11 is removed by the high pressure water sprayed from the sliding plate 17 and the sliding plate 17 that slides in close contact with the inner surface of the receiving portion 11, to the guide portion 14. Led. Further, when the pressure of the high-pressure water introduced into the cylinder 30 is lowered, the sliding plate 17 is retracted by the reaction force of the spring 33, and the excrement in the receiving portion 11 is similarly removed.

  And when excretion is complete | finished, the air cylinder 16 is operated and the piston 15 is advanced. The piston 15 moves from the position shown in FIG. 10 to the position shown in FIG. 12 through the state shown in FIG. Thereby, the opening part 12 of the cylinder part 13a is closed, and the excrement in the cylinder part 13a is pushed out to the discharge part 13b with the washing water. At this time, the valve 15b of the piston 15 is in a closed state, and all excrement is pushed out to the discharge portion 13b without entering the communication hole 15e.

  Then, the piston 15 is advanced from the state shown in FIG. 12 to the state shown in FIG. At this time, since the piston main body 15a is prevented from advancing by a stepped piston stopper 13d (see FIG. 10) formed in the cylinder portion 13a, the spring 15c is compressed and only the valve 15b is advanced. Thereby, as shown in FIG. 13, the communication hole 15e of the piston main body 15a is opened, and the front space and the rear space of the piston 15 are in a communication state.

  Next, the suction device 5 is operated in this state, and the excrement and washing water in the suction pipe 13 are sucked. At this time, since the opening 12 of the suction pipe 13 is closed, the suction pressure applied to the suction pipe 13 by the suction device 5 does not reach the shadow of the human body B or the like. 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.

  Further, since the front space and the rear space of the piston 15 are in communication with each other during suction by the suction device 5, air is drawn from the rear space of the piston 15 through the filter 20 when the excrement is sucked from the suction pipe 13. Therefore, excrement is sucked with this air. The forward movement of the valve 15b may be performed by the suction force of the suction device 5 without being performed by the air cylinder 16.

  When the excretion of the excrement is completed, the air cylinder 16 is moved in the reverse direction and returned to the position shown in FIG. Here, when the piston body 15a is separated from the piston stopper 13d, the valve 15b is retracted by the reaction force of the spring 15c, and the communication hole 15e of the piston body 15a is closed.

  As described above, in the wearable excretion device 1 according to the present embodiment, a user who is difficult to perform an independent excretion can perform an excretion without feeling uncomfortable or painful without care of others. In particular, in the wearable excretory device 1, the excrement in the receiving portion 11 can be guided to the opening portion 12 by the sliding plate 17 and sucked and taken in by the suction device 5, so that the position is away from the opening portion 12. Even if there is excrement, it is possible to suck in and take in all of it. As a result, there has been a limit in using a strong suction force such as a vacuum device in order to capture all the excrement that has been separated from the opening 12 conventionally, but the wearable excretory device 1 has a low output. Since all the excrement can be taken in by the suction device 5, noise during suction is reduced, and an inexpensive wearable excretion device 1 can be realized.

  Further, in the wearable excretory device 1 in the present embodiment, the sliding plate 17 slides in the receiving portion 11 while spraying water, so that excrement in the receiving portion 11 is opened by sliding of the sliding plate 17. When guided to the part 12, the excrement in the receiving part 11 can be removed by the water sprayed from the sliding plate 17, and the excrement in the receiving part 11 can be removed cleanly. In the present embodiment, sliding of the sliding plate 17 and injection from the injection port 17a are performed by water pressure, but high-pressure air can be used instead of high-pressure water. In addition, when water is used, since the water washing effect in the receiving part 11 is also acquired, since the excrement in the receiving part 11 can be removed more beautifully, it is desirable.

  Further, since the sliding plate 17 is formed of an elastic material, when sliding along the inner surface of the receiving portion 11, the sliding plate 17 bends so that the sliding plate 17 comes into close contact with the inner surface of the receiving portion 11. Move. Therefore, it is possible to remove all the excrement adhered to the inner surface of the receiving part 11 and remove the excrement in the receiving part 11 more neatly. In addition, since the sliding plate 17 should just slide along the inner surface of the receiving part 11, it is also possible to use hard materials, such as a plastic and a metal.

  Further, the sliding plate 17 in this embodiment is operated by supplying high pressure water to both of the cylinders 30 provided at both ends by the hose 34, but can also be operated by supplying to either one. It is. It is also possible to provide the spring 33 on either side or provide the spring 33 on the opposite side of the piston 31. Further, as shown in FIG. 2, in this example, the sliding plate 17 is expanded and contracted from the front to the rear of the apparatus main body 2, but conversely, the sliding plate 17 is configured to be expanded and contracted from the rear to the front of the apparatus main body 2. It is also possible.

  Further, in the illustrated example, the cylinder 30, the piston 31, and the piston rod 32 are linear, but it is also possible to configure them in a curved shape in accordance with the inner surface of the curved receiving portion 11. Alternatively, the cylinder 30, the piston 31, and the piston rod 32 may be made of a flexible material such as a rubber tube so as to be deformed in a curved shape along the inner surface of the receiving portion 11.

  In the present embodiment, high-pressure water is supplied to the sliding plate 17 through the cylinder 30, the piston 31, and the piston rod 32 and is injected from the injection port 17a. However, a flow path different from these is formed. It is also possible to inject from the injection port 17a of the sliding plate 17. It is also possible to adopt a configuration in which high-pressure water is received from a place other than the sliding plate 17 into the part 11 or the guide part 14.

  In addition, in the wearable excretion apparatus 1 according to the present embodiment, the opening 12 is closed and the excretion of the excretion into the discharge portion 13b is completed simply by moving the piston 15 forward in the cylinder portion 13a of the suction pipe 13. It is not necessary to separately provide a shutter that covers the portion 12, and the number of parts can be reduced. In addition, in the cylinder portion 13a that is airtight due to the opening 12 being covered, the valve 15b at the tip of the piston 15 is opened, so that the front space of the piston 15 and the rear space that is open to the atmosphere communicate with each other. Therefore, it is possible to prevent the excrement from being sucked smoothly due to a decrease in the atmospheric pressure in the suction pipe 13 at the time of suction by the suction device 5, and it is possible to suck the excrement with a light suction force. .

  In addition, the wearable excretory apparatus 1 is configured to directly mount the mounting portion 10 on the crotch portion of the human body B, but may be configured to be worn through a leg as a pants-type as in the past. Moreover, it is also possible to adopt a configuration in which a band or the like is used for fixing so as not to be displaced when attached to the crotch portion of the human body B.

  The wearable excretion apparatus of the present invention is useful as an excretion apparatus that is worn on a human body such as a sick person or a patient who needs care and receives excrement.
