Description

The present invention also relates ambulation is difficult old man, hospitalized patients, the disabled, the automatic urine collection processing equipment to process the urination by attaching to a person difficult to dispose of or to control the urination in the other of their own will .

  In general, elderly people, physically handicapped persons, inpatients with injuries and illnesses may have difficulty controlling urination on their own will, and it may be difficult to clean up urine by themselves. In this case, generally, a tube is directly inserted into the bladder to collect urine, or a disposable diaper is used.

  When inserting a tube directly into the bladder, there is a great deal of discomfort for the user, and there is a high possibility of damaging the urethra and bladder and causing infections. Processing becomes difficult.

  In addition, disposable diapers may cause urine leakage when worn for a long time, and may cause discomfort to the wearer, and skin diseases such as stuffiness and covering. Therefore, frequent replacement is required, and the mental and physical burden on the wearer and caregiver increases. Mental and physical burdens occupy a very large proportion of daily life, and the economic burden also increases.

  In order to solve such a problem, an automatic urine disposal apparatus has been proposed in which urine absorbed in a urine absorbent material of a urine receiver is sucked by a vacuum pump and guided to a urine tank. The vacuum pump sucks the air in the sealed urine tank and guides the urine absorbed by the urine receiver to the urine tank by the urine guide tube by the differential pressure from the atmospheric pressure. Such an automatic urination processing apparatus is described in Patent Documents 1 and 2 described above, for example.

JP-A-7-171182 JP-A-8-191852

  In the prior art, the urine receiver is brought into contact with the urine drainage part of the wearer, that is, the urine absorbing material of the urine receiver is opened to the atmosphere so that urine is sucked. The urine collection efficiency is reduced. For this reason, the amount of residual urine from the urine receiver (urine absorption material) increases, which causes discomfort to the wearer. In order to reduce the amount of residual urine from the urine receiver, the capacity of the vacuum pump must be increased, and the weight and volume of the urine treatment apparatus itself must be increased. Therefore, the situation is that it cannot be put into practical use as a portable urine collecting device.

  As described above, the conventional technique has a problem that the amount of residual urine from the urine receiver increases and the urination processing apparatus becomes large and heavy when it is attempted to reduce the amount of residual urine.

An object of the present invention improves the urinary recovery from urine receiver is to provide an automatic urine collection processing equipment that can be compact and lightweight.

  A feature of the present invention is that a urine sheet is disposed on the surface of a urine absorbing sheet so that when the urine excreted into the top sheet flows, the urine is diffused and permeated over the entire surface to become a non-breathable state. A receiver is used to lead urine by a vacuum pump from a urine inlet of the urine receiver to a urine tank that is sealed through a urine guide tube.

  In other words, the present invention arranges a hydrophilic sheet that becomes non-breathable by urine on the surface of a urine absorbing sheet housed and disposed in a non-water-permeable, non-breathable outer sheet, and the urine absorbing sheet is the outer sheet when urinating And a hydrophilic sheet to keep the air tightness (sealing) of the ventilation high, and urine is sucked by a negative pressure at the urine opening formed in the outer skin sheet by a vacuum pump, and through the urinary tube It leads urine to the urine tank.

  Here, the hydrophilic sheet in the present specification is a sheet having air permeability, water permeability, water immersion, and a property of diffusing and penetrating urine over the entire surface by surface tension or the like.

  The urine receiver used in the present invention holds the urine absorbing sheet at the time of urinary excretion with the airtightness of the skin sheet and the hydrophilic sheet being increased, so that the urine recovery rate from the urine receiver by the vacuum pump is improved and the The amount of residual urine from the urine receiver can be reduced. When the recovery rate of urine is improved, urine can be sucked with a small-capacity vacuum pump having a small suction force. Therefore, the urine receiver can collect urine without causing discomfort to the wearer, and the apparatus can be reduced in size and weight.

  In addition, in order to make the urine collection device compact, lightweight and portable, it is determined based on statistical data on the maximum urine flow rate by adults. In other words, a slight time difference from the start of urination is considered for the purpose of effectively processing the urine volume at the time of one urination, and the exhaust capacity of the vacuum evacuation device that can be effectively aspirated without much delay from the end of urination. The structure of the urine receiver and the diameter size of the urine sucking tube are optimized to reduce the size and weight of the vacuum exhaust device.

  Specifically, the capacity of the vacuum evacuation device is determined as follows. That is, according to the magazine “Urban Bulletin” Vol. 33, No. 4, published in April 1987, pages 521 to 526, the maximum urine flow rate for adults is 28.2 ± 4.6 ml per second. The urine collecting device of the present invention takes into account the time delay when collecting urine, etc., and the evacuation speed necessary for suitably sucking the urine volume temporarily stored in the receiver into the urine tank without overflowing from the receiver From the urine flow rate, the maximum safety rate is set to 40 ml per second. Moreover, in order to maintain low noise and high performance of the vacuum exhaust device (vacuum pump), a positive displacement vacuum pump that can exhibit high performance at a vacuum pressure of about 50 kPa is used. In particular, it is desirable to use a scroll type or oscillating piston type positive displacement vacuum pump capable of achieving high performance.

  In the present invention, a battery can be used as a power source by reducing the size and capacity of the vacuum exhaust device. In addition, various components such as the control circuit are miniaturized and mounted with high density, so that the entire apparatus is reduced in size and weight, and is portable.

  The capacity (size) of the urine tank is an important point for portability. The present invention can be adapted to urine tanks of various capacities. That is, a large capacity of about 800 ml is available for long-time use, such as at night, and a capacity of about 200 ml is freely detachable when it is desired to make it smaller by wearable use. The attachment / detachment diameter and attachment / detachment mechanism of the connecting part of the urine collecting tube and the urine tank are the same even if the capacities are different, so that the urine tank capacity can be freely changed according to preference. Furthermore, the present invention uses a joint that can connect the attachment / detachment mechanism of the connecting portion with one touch.

  As described above, the present invention uses the scroll type vacuum pump to control the operation so as not to suck the gas together with the urine during the urine suction by the optimum design of the urine suction system as described above in order to reduce the noise during the urine suction. Therefore, the noise is further reduced. This is a characteristic of the scroll-type basic structure, and it is possible to further reduce noise by eliminating the need for a valve mechanism that was a noise source in other types of pumps. In addition, the scroll-type vacuum pump is compact and has excellent exhaust characteristics and reliability.

  In order for patients or caregivers to be able to handle urination in a sanitary and simple manner without filth, parts that come into contact with urine, such as buffers, tubes, and urine tanks, should be made of water-repellent materials, Or by applying a super-water-repellent surface treatment, urine adherence and residue are extremely small, improving hygiene. Therefore, the trouble of frequently cleaning the parts can be saved. In addition, the urine tank is a joint that can be replaced with a single touch, and not only the deodorizing filter, but also the urine tank has a urine absorbing function and a disposable urine absorbing material with a deodorizing function. This eliminates the problem of odor, and the urine absorbing material inside can be easily removed by gravity and discarded without touching it.

  In the present invention, urine can be sucked by a small-capacity vacuum pump, the urine collection rate from the urine receiver can be improved, and the amount of residual urine from the urine receiver can be reduced, so that urine can be collected without causing discomfort to the wearer of the urine receiver. The apparatus can be reduced in size and weight.

  Moreover, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when used as a portable automatic urine collection processing apparatus. Furthermore, since the apparatus is reduced in size and weight and no extra air is sucked in by the vacuum pump, noise can be reduced, so that urine processing can be performed without causing trouble to others even when used in a hospital room at night.

  The urine receiver absorbs urine excreted from the urination part of the wearer. The urine tank is sealed with a lid. The urine swing suppression means suppresses the swing of urine flowing into the urine tank. The urine is guided from the urine receiver through the lid to the urine tank by a urinary tube. Air in the urine tank is sucked by a vacuum pump. The urine sensor detects that urine has been inhaled into the urine receiver and activates the vacuum pump. The urine receiver is disposed on the upper side of the urine absorbing sheet, a non-water-permeable outer sheet in which a urinary opening to which a urinary tube is connected is formed, a multilayer urine absorbing sheet stored and held in the outer sheet. The breathable, water-permeable surface sheet is disposed between the surface sheet and the urine absorbing sheet so as to cover the surface of the urine absorbing sheet. It has a hydrophilic sheet.

  One embodiment of the present invention is shown in FIGS. 1 is an overall configuration diagram of an automatic urine collection processing apparatus according to the present invention, FIG. 2 is a configuration diagram of a top view of a urine receiver, FIG. 3 is a configuration diagram of a bottom view of the urine receiver, and FIG. FIG. 5 and FIG. 5 show AA enlarged sectional views of FIG.

  1-5, the urine receiver 1 which absorbs the urine excreted from the urination part of the wearer (not shown) is configured in a substantially rectangular shape as shown in FIGS. 2 and 3, and is located between the wearer's crotch. The width of the substantially central region in the longitudinal direction (front-rear direction of the wearer) is narrowed and formed into a narrowed shape. The reason why the substantially central portion of the urine receiver 1 is narrowed is to fit the wearer's crotch.

  As shown in FIG. 4, the urine receiver 1 includes a top sheet 2, a hydrophilic sheet 3, a urine absorbing sheet 4, a skin sheet 5, and a gather 6. The top sheet 2 is a water-permeable, breathable nonwoven fabric, the hydrophilic sheet 3 is a nonwoven fabric composed of fibers made of polypropylene, polyethylene, rayon, or a composite of two or more fibers selected from these. The urine sheet 4 is formed of a water-permeable nonwoven fabric, cotton-like pulp, a polymer absorbent combination forming material, and the skin sheet 5 and the gathers 6 are formed of a non-water-permeable nonwoven fabric or film.

  The outer skin sheet 5 is a non-water-permeable thin-walled sheet, and is made of, for example, a polyethylene film. The outer sheet 5 may be a non-water-permeable member, but it is desirable to use a member made of a material that takes into account the stuffiness when worn for a long time. The outer surface (surface) of the outer sheet 5 is laminated with a surface material (not shown) such as a polypropylene non-woven fabric so as to soften the touch and eliminate the discomfort of the wearer. Further, the inner surface of the outer skin sheet 5 is subjected to a surface treatment so as to have water repellency.

  The outer sheet 5 is formed with a three-dimensional gather 6 inclined and planted inside the outer contour of the outer sheet 5 as shown in FIG. 5 along the contour in the longitudinal direction (front and rear direction of the wearer) and the width direction. ing. The three-dimensional gather 6 that is inclined and planted prevents leakage of urine due to the movement of the wearer or movement of the body position. Further, the outer skin sheet 5 is provided with a through hole 7 through which the urine guide tube 8 passes.

  As shown in FIG. 5, the urine absorbing sheet 4 is adhered and accommodated on the surface (upper surface) of the outer skin sheet 5. Two urine sensors 9 are provided on the urine absorbing sheet 4. The hydrophilic sheet 3 is adhered and disposed so as to cover the surface of the urine absorbing sheet 4. The hydrophilic sheet 3 and the urine absorbing sheet 4 are configured in substantially the same shape as shown in FIG.

  An air permeable and water permeable surface sheet 2 is disposed on the surface of the hydrophilic sheet 3. The surface sheet 2 is formed of, for example, a non-woven fabric so as to minimize friction with the wearer's skin. Further, the nonwoven fabric used as the top sheet 2 has a mesh sheet as the surface in contact with the skin in the vicinity of the wearer's urine area to increase water absorption and sweat absorption, and urine quickly flows into the hydrophilic sheet 3 from the fine pores of the mesh sheet. Like to do. The wearer quickly sucks urine into the urine absorbing sheet 4 through the hydrophilic sheet 3 to reduce the wet feeling in the vicinity of the urination portion.

  One end of the urinary tube 8 is bonded to the urine opening 7 formed in the outer skin sheet 5. The other end of the urinary tube 8 is connected to the one-touch joint 11. The one-touch joint 11 is attached to one end of the urinary tube 12, and the other end of the urinary tube 8 and one end of the urinary tube 12 are connected by the joint 11. The urinary tubes 8 and 12 are formed of a soft flexible material such as a soft resin, and the one-touch joint 11 is formed of a soft material.

  The urine tank 15 is formed in a bottomed elliptical cylinder shape with cardboard such as a milk pack or an environmentally friendly plastic material, and a partition plate 16 is provided inside. A plurality of suction holes 17 are formed in the partition plate 16. The capacity of the urine tank is 500 ml as a standard capacity, but it is about 200 ml for small ones and 800-1000 ml for long hours such as nighttime so that it can be changed according to the form when using the urine collecting device. There are several types of capacity including medium capacity. Further, an arcuate protrusion 18 is formed on the outer periphery of the urine tank 15 so as to closely fit with the lid container 20. In the urine storage space 15a of the urine tank 15, a highly water-absorbing resin 19 that is gelled when urine is absorbed is stored. The superabsorbent resin 19 is a particulate resin, and for example, cross-linked sodium polyacrylate is used. The highly water-absorbent resin 19 constitutes urine swaying suppression means that suppresses urine swaying (waving) in the urine tank 15.

  Similarly to the urine tank 15, the lid container 20 is formed in an elliptical cylinder shape with paper or the like, and a lid plate 21 serving as a lid of the urine tank 15 is provided at the lower part. The urine tank 15 is sealed with a lid plate 21 when the lid container 20 is fitted. An upper opening of the lid container 20 is closed by fitting a deodorizing filter material 22. The deodorizing filter material 22 also serves as a lid of the lid container 20 and is provided with an exhaust hole 23. In addition, an arcuate recess 28 that is elastically engaged with the arcuate protrusion 18 of the urine tank 15 is formed in the lower part of the lid container 20.

  A vacuum pump 24 is disposed in the internal space between the lid plate 21 of the lid container 20 and the deodorizing filter material 22. The vacuum pump 24 is driven by a motor 25. The motor 25 is controlled by a control device mounted on a control board 27 using the battery 26 as a driving power source. As the battery 26, an alkaline battery, a secondary battery, or the like is used. The physique of the vacuum pump 23 is small with a diameter of 30 mm and a length of about 70 mm or less, and the voltage of the battery 26 is about 5 to 9V.

  The other end of the urinary tube 12 is disposed so as to pass through the lid container 20, the lid plate 21, and the partition plate 16 of the urine tank 15 and to be positioned above the urine storage space 15 a of the urine tank 15. Further, the other end of the suction tube 30 having one end connected to the vacuum pump 24 is disposed in a space between the lid plate 21 and the partition plate 16. The suction tube 30 is also formed of a soft flexible material like the urinary tubes 8 and 12.

  The specifications of the vacuum exhaust device (vacuum pump 24) are as follows. According to the above-mentioned magazine, the maximum urine flow rate in young adults (19-39 years old) is reported to be 28.2 ± 4.6 ml per second. It is higher than any other age. For safety reasons, the maximum urine flow rate is 40 ml per second with reference to this result. If only urine is aspirated without air entrainment, the pumping speed of the vacuum pump 24 is 40 ml per second, and the diameter of the urination hole and the urinary tube By optimizing the diameters 8 and 12, urine can be aspirated without overflow in the urine receiver 1. Therefore, in this embodiment, the volume of the urine absorbing sheet (buffer portion) 4 is set to 80 ml so that there is a margin of 2 seconds for urination at the maximum urine flow rate, and the urine inlet (urine hole) 7 and the urine tubes 8, 12 are used. The inner diameter is 3 to 4 mm.

  The pumping speed of the vacuum pump 24 is 40 ml per second, but this pumping speed varies proportionally with the rotating speed. Therefore, the rotating speed is determined from the viewpoint of reliability that the vacuum pump 24 is operated without vibration, noise and no lubrication. Is to operate at less than 5000 revolutions per minute. By minimizing the exhaust capacity of the vacuum pump 24 in this way, the size of the vacuum pump 24 can be made very small, 30 mm in diameter and 70 mm in length, and can be driven by a battery (battery) 26 of 12 V or less. Yes. In the vacuum pump device, the mechanical parts and motor shown in FIGS. 8 and 9 below are integrally formed, and a DC motor is adopted as the motor.

  An example of the vacuum pump 24 is shown in FIGS. FIG. 8 shows a scroll type vacuum pump, and FIG. 9 shows an oscillating piston type vacuum pump.

  In FIG. 8, the scroll-type vacuum pump has a pump chamber formed by meshing spiral wraps as shown. In the pump chamber, the orbiting scroll 30 and the fixed scroll 31 mesh with each other to form a crescent-shaped space 32. Openings 33 and 34 are provided at the outer peripheral portion and the central portion of the fixed scroll 31.

  The orbiting scroll 30 is configured to perform an orbiting motion while maintaining a minute gap to maintain a sealing property with respect to the fixed scroll 31 stationary by the drive shaft 35 in a state where rotation is prevented. When the orbiting scroll 30 orbits at a constant radius, the crescent-shaped space 32 moves while decreasing its volume from the outer peripheral side toward the center, thereby forming the compression working chamber 32. As a result, the gas is sucked from the opening 33 on the outer periphery, compressed as it moves to the center, and discharged from the opening 34 in the center, that is, the discharge port 34.

  The plurality of crescent-shaped spaces 32 each have a sealing point and have a self-compression type characteristic, so that the compressed gas flows backward from the central portion 34 to the outer peripheral portion while the orbiting scroll 30 moves. Does not occur. Therefore, a discharge valve that prevents backflow is not necessary, and noise during operation is not generated, so that the noise during operation is quiet. Further, since the motion of the orbiting scroll 30 is a kind of rotational motion, vibration due to unbalance can be kept at a very small level.

Thus constructed scroll pump, without the lubricating oil into the compression operation chamber can be operated at high, connects the opening portion of the outer peripheral portion of the fixed scroll 31 before Symbol urine tank 5, the opening of the central portion It functions as a vacuum pump by opening it to the atmosphere.
In order to set this pump to 5000 rpm or less and the evacuation speed to 40 ml per second, the turning radius of the orbiting scroll 30 can be set to 0.9 mm, the wrap height to 5 mm, and the wrap thickness to 0.75 mm. it can. As a result, the size of the outer periphery can be reduced to 30 mm or less.

  Further, by using polyphenylene sulfide resin, which is a kind of engineering plastic, for the orbiting scroll 30 and the fixed scroll 31, it can withstand long-term use without being corroded even if it touches a gas smelling urine. Moreover, since the specific gravity is small, a large weight reduction can be achieved.

  Next, the main part of the oscillating piston type vacuum pump is shown in FIG.

  As shown in FIG. 9, the oscillating piston type vacuum pump is composed of a cylinder 40 and an oscillating piston 41. The oscillating piston 41 is formed by integrating an annular portion 42 and a flat plate portion 43, and the flat plate portion 43 is supported by a slider 44 arranged so as to be able to rotate and slide on the cylinder 40.

  On the other hand, the annular portion 42 is rotated by the crankshaft 49, and its central portion is fitted with a shaft portion that is eccentric with respect to the rotating shaft 49. For this reason, the movement of the swing piston 41 swings while partially contacting the inner wall surface of the cylinder 40 in a state where rotation is prevented even when the crankshaft 49 rotates.

  The cylinder 40 is provided with a pair of openings 47 and 48 so as to sandwich the flat plate of the swing piston 41 in the vicinity of the slider 44. When the shaft rotates clockwise, the volume 45 of the right side of the flat plate 43 increases in volume, and the volume of the space 46 on the left side decreases. As a result, the right side becomes the suction chamber 45 and the left side becomes the compression chamber 46. The flat plate 43 can maintain a good sealability between the left and right spaces even without lubricating oil. A high performance vacuum pump can be constructed by connecting the opening 47 of the cylinder on the suction side to the urine tank 5 and opening the other opening 48 to the atmosphere.

  In order to set the oscillating piston type vacuum pump at 5000 rpm or less and the evacuation speed to 40 ml per second, the rotational radius of the oscillating piston 41 is 1.4 mm, the width of the piston is 15 mm, and the inner diameter of the cylinder 40 is 17 mm. .2 mm can be set. As a result, the size of the outer periphery can be reduced to 30 mm or less.

  In addition, by making the cylinder 40 and the oscillating piston 41 a polyphenylin sulfide resin, which is a kind of engineering plastic, it can withstand long-term use without being corroded even if it touches a gas that smells of urine. . Moreover, since the specific gravity is small, a large weight reduction can be achieved.

  In this way, the capacity of the vacuum pump is reduced and the buffer unit 4 is provided so that the urine can be sucked in by reducing the amount of air involved as much as possible. Can also be reduced. As a specific example, the noise level of a conventional large pump is 30 to 50 dB, whereas in this embodiment, it can be 30 dB or less.

  The urine sensor 9 that detects that urine has been urinated on the top sheet 2 is electrically connected by urination. The urine sensor 9 is an electric conductor, and detects urination of the wearer by a change in resistance value. A urine detection signal detected by the urine sensor 9 is applied to a control board 27 that controls the vacuum pump 24 via signal lines 31 and 32. The signal lines 31 and 32 are connected by a one-touch joint 33.

  In this configuration, the urine receiver 1 is mounted in the underwear of a wearer (not shown) so that the topsheet 2 comes into contact with the urine drainage part. The lid container 20 containing the urine tank 15, the vacuum pump 24, the motor 25 and the like is carried by the wearer or placed on or under the bed when the wearer is sleeping on the bed.

  When the wearer urinates in this state, the urine urinated by the urine receiver 1 is absorbed by the top sheet (nonwoven fabric) 2 and flows (permeates) into the hydrophilic sheet 3. The hydrophilic sheet 3 diffuses and penetrates urine over the entire surface by surface tension. The hydrophilic sheet 3 is filled with urine between the fibers and becomes non-breathable. When urine is absorbed from the hydrophilic sheet 3 to the urine absorbing sheet 4, the urine sensor 9 is electrically connected to apply a urine detection signal to the control board 27. The control device mounted on the control board 27 activates the motor 25 and drives the vacuum pump 24.

  When the air in the urine tank 15 is exhausted by driving the vacuum pump 24, the air pressure in the urine storage space 15 a is lowered, and a negative pressure is generated at the urine inlet 7 of the outer skin sheet 5. The hydrophilic sheet 3 is in a non-breathable state due to urination, the skin sheet 5 is non-breathable, and the urine absorbing sheet 4 is kept highly air-tight.

  When the urine inlet 7 becomes negative pressure, the urine absorbed in the urine absorbing sheet 4 is efficiently sucked into the urinary tube 8 by the suction force due to the negative pressure. The urine sucked into the urinary tube 8 is guided and stored in the urine storage space 15a of the urine tank 15 through the urine tube 12 by negative pressure.

  The inner surface of the outer skin sheet 5 is subjected to water repellent treatment, and the urine absorbed in the urine absorbing sheet 4 is promptly guided to the urine opening 7.

  The urine guided to the urine storage space 15a of the urine tank 15 reacts with the particulate high water-absorbing resin 19 to be gelled. When the urine is gelled, it can be prevented from swinging (waving) in the urine tank 15. Therefore, there is no fear of urine leakage even if it is used for portable purposes, and it can be configured in a desirable form as a portable automatic urine collection processing device.

  When the excretion of the wearer ends and the urine detection signal from the urine sensor 9 disappears, the control device mounted on the control board 27 stops the motor 25 and also stops the vacuum pump 24. When the volume of the urine tank 15 can store urine for two times, the next urine collection process is performed in the same manner.

  The urine stored in the urine tank 15 disconnects the urinary tubes 8 and 12 by the one-touch joint 11 and disconnects the signal lines 31 and 32 by the one-touch joint 33, and then separates the urine tank 15 and the lid container 20. The urine tank 15 is discarded. The urine tank 15 is made of paper or environmentally friendly plastic, can be incinerated, and can be discarded as a combustible material.

  If the urine receiver 1 becomes dirty after about one day of use or due to defecation, the urinary tube 8 and the urine sensor 9 are disconnected by the joints 11 and 33, and the urine receiver 1 is discarded. Wear to the wearer.

  In this way, the urination of the wearer is processed. The urine receiver 1 of the present invention holds the urine absorbing sheet 4 with the skin sheet 5 and the hydrophilic sheet 3 at a high airtightness during urination. Therefore, the urine recovery rate from the urine receiver 1 by the vacuum pump 24 is improved, and the amount of residual urine from the urine receiver 1 can be reduced. When the urine recovery rate is improved, urine can be sucked with a small-capacity vacuum pump 24 having a small suction force. Therefore, the urine receiver 1 can collect urine without causing discomfort to the wearer, and the apparatus can be reduced in size and weight.

  Moreover, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when used as a portable automatic urine collection processing apparatus. Furthermore, since the apparatus is reduced in size and weight and no extra air is sucked in by the vacuum pump, noise can be reduced, so that urine processing can be performed without causing trouble to others even when used in a hospital room at night.

  FIG. 6 shows another example of the urine receiver 1.

  The urine receiver 1 shown in FIG. 6 is different from the urine receiver in the above-described embodiment in that the urine absorbing sheet 4 is formed by laminating the multilayer (three layers) 4a, 4b, and 4c, and the urine absorbing sheets 4a, 4b, and 4c are formed. Is to make a difference in water absorption (water retaining ability) and to increase water absorption as the lower layer is formed as 4a <4b <4c.

  The difference in water absorption between the urine absorbing sheets 4a, 4b, and 4c can vary the density and wettability of the fibrous skeletal material having voids, for example. By making the water absorption of the urine absorbing sheets 4a, 4b, and 4c different in this way, urine is easily collected on the lower urine absorbing sheet 3c having high water absorption. Since urine collects in the lower urine absorbing sheet 4c in contact with the outer skin sheet 5 in which the urinary opening 7 is formed, urine absorption can be performed effectively.

  The urine absorbing sheets 4a and 4b can be formed of a material having fibers in the vertical direction (thickness direction) to collect urine in the urine absorbing sheet 4c without leaking urine in the horizontal direction.

  Moreover, the same effect can be acquired even if it makes the hydrophilic sheet | seat 3 a multilayer without using the urine absorption sheet | seat 4, and gives a difference in water absorption (water retention ability).

  FIG. 7 shows another example of a urine tank (including a lid container).

  The urine tank 15 shown in FIG. 7 differs from the urine tank in the above-described embodiment shown in FIG. 1 in that the urine tank 15 and the lid container 20 are formed in a rectangular parallelepiped shape, and the porous urine absorbent material 35 is used as a urine swing suppressing means. It is to have established. As the porous urine absorbent material 35, sponge, pumice, or the like is used.

  In FIG. 7, a lid plate 36 is provided in the lid container 20, and a deodorizing filter 38 is disposed in the lid container 20 so as to suck air in the urine tank 15 from the suction tube 39. The vacuum pump 24 discharges through the discharge tube 37. The motor 25 is behind the vacuum pump 24 and is not shown.

  Even with this configuration, the urine guided to the urine storage space 15a of the urine tank 15 is absorbed by the porous urine absorbing material 35, so that it is possible to prevent the urine tank 15 from wobbling (waving). it can.

  As described above, the present invention can improve the urine recovery rate from the urine receiver and reduce the residual urine volume of the urine receiver. When the urine recovery rate is improved, urine can be sucked from the urine collecting sheet with a small-capacity vacuum pump having a small suction force. Therefore, the urine receiver can collect urine without causing discomfort to the wearer, and the apparatus can be reduced in size and weight.

  Moreover, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when used as a portable automatic urine collection processing apparatus. Furthermore, since the apparatus is reduced in size and weight and no extra air is sucked in by the vacuum pump, noise can be reduced, so that urine processing can be performed without causing trouble to others even when used in a hospital room at night.

  Further, in the above-described embodiment, the urine tank is made of paper or environmentally friendly plastic, can be incinerated, and can be discarded as combustible material. As a result, it is possible to obtain a urine treatment device that is friendly to the natural environment.

  In the above-described embodiment, the hydrophilic sheet becomes non-breathable when it absorbs urine, but it goes without saying that it may be in a non-breathable state with some breathability.

  Obviously, the urine swing suppression means may solidify urine. Furthermore, the urine sensor can transmit a urine detection signal wirelessly using an IC chip.
