{PTL 1}: Specification of Patent Application No. 2011-011411
Wearers of such type of urine receptacle are often the aged and/or severely disabled persons and many of these persons spend most of the day on the their beds. Furthermore, these persons spend most of the time on the bed in a supine posture or in a lying posture.
In this known urine disposal device, the urine collecting container is arranged on the skin-contact surface of the urine receptacle wearer being in a supine posture and, when the wearer has evacuated the bowels (excrement), the end portion of the first connector tube will be soiled with the excrement. Thereafter, when the used urine receptacle is exchanged with the fresh one, the end portion of the first connector tube soiled with the excrement must be cleaned. Thus the known urine disposal device has left behind a problem that it takes a lot of trouble to exchange the urine receptacle.
In view of this, an object of the present invention is to provide a urine disposal device improved so as to alleviate a possibility that the connector might be soiled with the wearer's excrement.
Some embodiments of the present invention provide a urine disposal device having a longitudinal direction, a transverse direction and a thickness direction and including a urine receptacle and adapted to connect the urine receptacle through a connector to an external equipment at least including a vacuum pump to suction urine from the urine receptacle.
The present invention lies in that the urine receptacle has a first surface facing a wearer's skin, a second surface not facing the wearer's skin when the wearer is in a supine posture and a connecting region in which the connector is connected wherein the connecting region is arranged on the second surface.
The present invention may at least include embodiments as described below.
(1) The urine receptacle is disposed with a urine collecting container having an internal space. The urine collecting container includes an internal outlet port arranged within the internal space and an external outlet port arranged on the outside of the internal space and a tubular member adapted to put the internal outlet port and the external outlet port in a fluid-communication relationship wherein the external outlet port functions also as a connecting region.
(2) The urine receptacle has an opening extending in the transverse direction. The urine collecting container is arranged so that a urine evacuation direction from the internal outlet port to the external outlet port may be oriented oppositely to the opening.
(3) The urine receptacle has an opening extending in the transverse direction. The urine collecting container is arranged so that the urine evacuation direction from the internal outlet port to the external outlet port maybe oriented toward the opening.
(4) The urine receptacle is formed from a plurality of sheets made of a thermoplastic synthetic resin in a bag-like shape defining therein a urine receiving space in fluid-communication with the opening. High stiffness regions are formed in the course of heat sealing a plurality of sheets but the high stiffness regions are formed only on lateral edges of these sheets as a portion of the opening's periphery.
(5) The respective high stiffness regions have centers. The urine collecting container is arranged so that the internal space may be positioned within an overlapping region in which a region defined under a first imaginary line extending so as to pass through the center of one of two high stiffness regions spaced apart from each other in the transverse direction and to be tangent to the internal space on the upper side of the urine collecting container and a region defined under a second imaginary line extending so as to pass through the center of the other high stiffness region and to be tangent to the internal space on the upper side of the urine collecting container overlap each other.
In the urine disposal device according to the present invention put on the wearer in a supine posture, the connecting region of the urine receptacle is arranged on the second surface not facing the wearer's skin. In consequence, when the wearer discharges excrement, the urine receptacle covers the distal end portion of the connector and the connecting region, whereby the distal end portion of the connector and the connecting region are unlikely to be soiled with the excrement. In addition, the connecting region should not come in contact with the wearer' s body since the connecting region is arranged on the second surface. In this way, it is possible to alleviate a sense of discomfort felt by the wearer, even if the urine collecting container is formed of a thermoplastic synthetic resin.

As illustrated in
The urine receptacle 11 is dimensioned so that a length dimension in the longitudinal direction Y is longer than a length dimension in the transverse direction X and disposed with a urine collecting container 13. The urine collecting container 13 of the urine receptacle 11 is connected to the urine tank 14 through the connector 12. The connector 12 are adapted also to connect the urine receptacle 11 to an external equipment O as described later and include a first connecting tube 12a and a joint 12b. The urine tank 14 is connected to the vacuum pump 15 through a second connecting tube 12b.
A control unit 17 is connected to the vacuum pump 15 through an electric wire 16 and an electric connector 20 is attached to a distal end of electric wires 18a, 18b extending from the control unit 17. The vacuum pump 15 functions to suction urine from a urine receiving space S described later.
The electric connector 20 has a first terminal (not shown) adapted for electrically connecting the electric wire 18a to a first electrode 51 arranged adjacent to an end 22a of a urine sensor 22 and a second terminal (not shown) adapted for electrically connecting the electric wire 18b to a second electrode 52 arranged adjacent to the end 22a of the urine sensor 22 so that such electric connection may be switched off as the occasion demands.
In the urine disposal device 10, the urine sensor 22 detects urine discharged into the urine receiving space S and this urine detection signal is inputted to the control unit 17. The control unit 17 activates an electric motor (not shown) disposed adjacent to the vacuum pump 15 to actuate this pump. Actuation of the vacuum pump 15 causes the amount of air within the urine tank 14 to be suctioned out from the urine tank 14. Urine having been retained within the urine receiving space S to be collected first is suctioned into the urine collecting container 13 and then transferred through the first connecting tube 12a into the urine tank 14 so as to be reserved therein.
In the description given hereunder, the constituents of the urine disposal device 10 except the urine receptacle 11 and the connector 12, such as the urine tank 14, the vacuum pump 15 as well as motor thereof and the control unit 17 will be generically designated as the external equipment O. In addition, while the urine receptacle 11 is electrically connected to the external equipment O so far as the present embodiment is concerned, it is not essential that the urine receptacle 11 is electrically connected to the external equipment O. For example, it is also possible to provide the electric connector 20 with a small sender so that a receiver set in the control unit 17 may receive the signals transmitted from the sender and, in response to such signals, the control unit 17 may activate an electric motor of the vacuum pump 15.
The urine receptacle 11 has the longitudinal direction Y, the transverse direction X being orthogonal to the longitudinal direction Y and a thickness direction Z being orthogonal to both the longitudinal direction Y and the transverse direction X (See
The urination region 24 and the extension flaps 25 have the same length dimension so far as the transverse direction X is concerned. The urination region 24 has a length dimension in the longitudinal direction Y corresponding to about 1/3 of the urine receptacle 11 and the extension flaps 25 have a length dimension in the longitudinal direction Y corresponding to about ⅔ of the urine receptacle 11. The urination region 24 has an opening 28 extending in the transverse direction X along a boundary line between the urination region 24 and each of the extension flaps 25. The opening 28 opens into the urine receiving space S defined within the urination region 24.
Referring to
The lateral edges 29c, 29d have rectilinear portions 29e between which the length dimension in the transverse direction X is kept constant and narrow portions 29f between which the length dimension in the transverse direction X is smaller than that between the rectilinear portions 29e. A pair of the narrow portions 29f are formed to face each other across the imaginary longitudinal center line Q and arranged adjacent to the opening 28 as illustrated in
The backsheet 30 has a length dimension in the transverse direction X larger than any constituent sheet in the laminated sheet structure 29. The backsheet 30 has a first end edge 30a and a second end edge 30b extending in the transverse direction X and lateral edges 30c, 30d extending in the longitudinal direction Y between the end edges 30a, 30b.
Referring again to
The backsheet 30 is formed of a liquid-impermeable material. For example, the backsheet 30 is formed of a liquid-impermeable SMS fibrous nonwoven fabric, a spunbond fibrous nonwoven fabric, a plastic sheet of polyethylene or a laminate thereof. In the urine receptacle 11 according to the present embodiment, a plastic film 30y and an SMS fibrous nonwoven fabric 30x (See
The backsheet 30 has a first fold line 32 extending in the transverse direction X along the first end edge 29a of the laminated sheet structure 29 and a second fold line 33 extending in the transverse direction X at a level between the first fold line 32 and the second end edge 30b. The backsheet 30 has lateral edges 34 on the outside in the transverse direction X of the laminated sheet structure 29. Referring to

In the exploded state as illustrated in
The protection sheet 39 serves to protect the topsheet 40 and is formed of a thermoplastic synthetic resin.
The topsheet 40 is formed of a liquid-permeable fibrous nonwoven fabric made of a thermoplastic synthetic resin, for example, formed of an air-through nonwoven fabric having a mass per unit area in a range of about 20 to about 40 g/m2.
Similar to the topsheet 40, the second sheet 41 is formed of a liquid-permeable fibrous nonwoven fabric made of a thermoplastic synthetic resin, for example, formed of an air-through nonwoven fabric having a mass per unit area in a range of about 15 to about 25 g/m2.
The elastic rebound sheet 42 is formed in a net-like fashion from a thermoplastic synthetic resin having an elastically rebounding property and has a liquid-permeable property since it is formed in the net-like fashion. The elastic rebound sheet 42 is formed of, for example, an ethylene-vinyl acetate sheet having a thickness in a range of about 0.5 to about 1.0 mm. The elastic rebound sheet 42 has an appropriate elastically rebounding force to tight up the wearer's genitalia inserted through the opening 28 into the urination region 22 and to prevent the genitalia from being displaced and to prevent urine from leaking out through the opening 28. If the elastic rebound sheet 42 is not provided and the second sheet 41 is left in contact with the urine sensor 22, a portion of urine might be left behind absorbed by the second sheet 41 to keep the second sheet 41 in wet conditions even after a process of urine suction has been finished. When the second sheet 41 in such wet conditions comes in contact with the urine sensor 22, for example, under a body weight of the wearer, the urine sensor 22 might erroneously detect urination. However, the elastic rebound sheet 42 is interposed between the second sheet 41 and the urine sensor 22 for the urine receptacle according to the present embodiment, whereby it is assured to prevent such erroneous detection. In this regard, the elastic rebound sheet 42 is preferably secured to the cushion sheet 44 through partially distributed adhesive to the cushion sheet 44 to assure the liquid-permeability of the cushion sheet 44.
The cushion sheet 44 is formed of a liquid-permeable nonwoven fabric sheet such as a thermal bond nonwoven fabric sheet or an SMS nonwoven fabric sheet formed from a thermoplastic synthetic resin. The cushion sheet 44 has, for example, a mass per unit area in a range of about 20 to about 30 g/m2. The cushion sheet 44 functions to prevent a portion of urine which might be present in the diffusion sheet 45, the suction backsheet 49 and the hard-breathable sheet 46 from flowing toward the electrodes 51, 52.
The diffusion sheet 45 is formed primarily from rayon fibers formed of a thermoplastic synthetic resin and hydrophilic fibers formed from a thermoplastic synthetic resin is mixed therewith to assure a liquid-permeability. The diffusion sheet 45 is used for the purpose of, as soon as urine is discharged, diffusing such urine in the transverse direction X as well as in the longitudinal direction Y, thereby rendering the suction backsheet 49 in wet conditions over a wide range. When the suction backsheet 49 becomes wet conditions, an internal space 64 of the urine collecting container 13 creates a negative pressure which, in turn, facilitates urine to be suctioned into the internal space 64 of the urine collecting container 13.
The suction backsheet 49 is formed of a thermoplastic synthetic resin. The suction backsheet 49 has a mass per unit area in a range of about 70 to about 80 g/m2 and, as material thereof, an airlaid fibrous nonwoven fabric may be used. The suction backsheet 49 has the function and the property similar to the hard-breathable sheet 46 and may be formed of the similar material.

The urine collecting container 13 is disposed with a tubular member 65 extending in the longitudinal direction Y across approximately central region. The tubular member 65 has an internal outlet port 65a arranged within the internal space 64 of the urine collecting container 13 and an external output 65b arranged at the outside of the internal space 64 so that the internal outlet port 65a and the external outlet port 65b may be in fluid-communication relationship. To the external output 65b, the first connector tube 12a is attached through the joint 12c (See
In the urine collecting container 13, a plurality of convexities projecting from the bottom are formed on both sides in the transverse direction X of the tubular member 65. In addition, a plurality of convexities 67 projecting toward the internal outlet port 65a are formed on a portion of the peripheral wall 61 facing the internal outlet port 65a.
Referring to
The internal space 64 of the urine collecting container 13 has a length dimension in the longitudinal direction Y which is smaller than ½ of a length dimension in the longitudinal direction Y of the urination region 24. The urine collecting container 13 is arranged adjacent to the second end edge 11b of the urine receptacle 1 so that the internal space 64 of the urine collecting container 13 is positioned in a lower half in the longitudinal direction Y of the urination region 24.
A region defined under a first imaginary line M1 passing through the centers of the respective high stiffness regions 80 positioned on one side in the transverse direction X and tangent to the internal space 64 on the upper side of the urine collecting container 13 and a region defined under a second imaginary line M2 passing through the center of the high stiff region 80 positioned on the other side in the transverse direction X and tangent to the internal space 64 on the upper side of the urine collecting container 13 overlap each other to define an overlapping region 90. The urine collecting container 13 is arranged in the urine receptacle 11 so that the internal space 64 may be positioned in this overlapping region 90. More specifically, in a state that the imaginary longitudinal center line Q extends in parallel to vertical lines M3, M4 passing through the centers of the respective high stiffness regions 80 positioned on respective sides in the transverse direction X, the internal space 64 of the urine collecting container 13 is arranged within the overlapping region 90 defined so that an angle 81 formed between the vertical line M3 passing through the center of the high stiffness region 80 on one side in the transverse direction X is 45° or less and an angle 82 formed between the vertical line M4 passing through the center of the high stiffness region 80 on the other side in the transverse direction X and the second imaginary line M2 is 45° or less. In this regard, the urine collecting container 13 is arranged in the illustrated embodiment so that the upper side of the internal space 64 may be tangent to the imaginary lines M1, M2 extending at angles θ1, θ2 of about 25°.
Referring again to
The leakage-barrier sheet 48 is formed from a laminate of two or more appropriately rectangular sheets formed from a thermoplastic synthetic resin. For example, the leakage-barrier sheet 48 may be formed of 4 to 8 air-through nonwoven fabric sheets having a mass per unit area in a range of about 30 to about 40 g/m2 laminated in the thickness direction Z. The leakage-barrier sheet 48 is arranged along the periphery of the opening 28.
Now the steps of assembling the urine receptacle 11 arranged as has been described hereinbefore will be described.
First, predetermined portions are cut away from the laminated sheet structure 29 illustrated in
The narrow portions 29f are arranged adjacent to the opening 28 as will be described later (See
After the hard-breathable sheet 46 has been attached to the urine collecting container 13 with the use of adhesive, the urine collecting container 13 is arranged on the backsheet 30 so that the external outlet port 65b of the urine collecting container 13 maybe exposed through an exposing hole 79 and, as illustrated in
Referring now to
Then, the backsheet 30 is folded along the first fold line 32 so as to cover the lower side leakage-barrier sheet 48 and, as illustrated in
Now, the laminated sheet structure 29 and the backsheet 30 are folded along the second fold line 33 of the backsheet 30. More specifically, the laminated sheet structure 29 and the backsheet 30 are folded so that the protection sheet 39 may face itself and be put in contact with itself, whereby the third end edge 30f and the second end edge 30b of the backsheet 30 are put in coincidence with each other as illustrated in
S in fluid communication with this opening 28 is formed within the urination region 24. The second fold line 33 defines the second end edge 11b of the urine receptacle 11.
After four corners of the backsheet 30 have been cut off, the sheets 39, 40, 41, 42, 44, 45 and 49 are heat sealed together in the thickness direction to form the high stiffness regions 80, thereby obtaining the urine receptacle 11 as illustrated in
Referring to
Referring again to
Each of the high stiffness regions 80 maybe formed as a circle having a diameter of 4 mm so as not to be put in contact with the narrow portion 29f.
The adhesive regions 30e are formed of the adhesive distributed over whole area on the upper surface of the backsheet 30 and exist also adjacent to the respective narrow portions 29f. In consequence, the backsheet 30 is joined to itself adjacent to the respective narrow portions 29f through the adhesive regions 30e and joined lateral edge portions 30g extending in the longitudinal direction Y are formed on both sides in the transverse direction X of the urination region 24.
Since the high stiffness regions 80 are arranged as has been described above, the respective joined lateral edge portions 30g have extensions extending in the longitudinal direction Y closer to the opening 28 than to the high stiffness regions 80. A distance dimension L1 between a pair of the high stiffness regions 80 in the transverse direction X is shorter than a length dimension L2 in the transverse direction X of the opening 28 (See
When it is desired to put the urine receptacle 11 on the genitalia, for example, the wearer's thumb is inserted into one of the narrow portions 29f and the wearer's first finger into the other narrow portion 29f.
Then the thumb and first finger may be moved closer to each other to assure that the mid portions in the transverse direction X of the respective sheets 39,40, 41, 42, 44, 45 and 49 having a relatively high bending moment are folded and the opening 28 is smoothly opened.
Now the forefront of the genitalia may be inserted into the opening 28 and further inserted toward the back of the urination region 24. The distance dimension L1 (See
Upon insertion of the genitalia to the back of the urination region 24, the thumb and the first finger maybe disengaged from the urine receptacle 11. Thereupon, the opening 28 is closed under the elastic rebounding force of the elastic rebound sheet 42. In this manner, as illustrated in
The high stiffness regions 80 are arranged closer to the imaginary longitudinal center line Q than the joined lateral edge portions 30g are. Consequently, pubic hair should not be caught by the adhesive regions 30e during insertion of the genitalia R.
A length dimension L3 in the longitudinal direction Y of the urination region 24 is preferably in a range of 50 to 180 mm and, more preferably, in a range of 80 to 130 mm.
The urination region 24 is the region adapted to receive the genitalia R inserted thereinto and to receive urine. In view of this, while it is rather preferable to determine the length dimension L3 in the longitudinal direction Y of the urination region 24 to be relatively long, if the dimension L3 is excessively long, the lower end of the urine receptacle might come in contact with a wheel chair on the assumption that the wearer is in the wheel chair when he urinates. In contrast, if the dimension is excessively short, it may be difficult to stably hold the genitalia within the urine receptacle. From this viewpoint, preferably an average length value of genitalia of Japanese men is calculated and the dimension L3 is determined in consideration of the calculated average value.
The distance dimension L1 in the transverse direction X between a pair of the high stiffness regions 80 is a factor substantially specifying the genitalia R which can be properly inserted into the urine receptacle 11. Considering the average genitalia thickness of Japanese men, the distance dimension L1 of 50 mm or more is sufficient to assure the desired function. Taking account of erection, the distance dimension L1 is preferably 75 mm or more. If the distance dimension L1 is excessively large, the elastically rebounding force of the elastic rebound sheet 42 might be insufficient to close the opening 28 and a portion of urine discharged into the urine receptacle might leak out through the opening. Specifically, the distance dimension L1 of 130 mm or more is inappropriate. From these viewpoints, the distance dimension L1 is preferably in a range of 50 to 130 mm and more preferably in a range of 75 to 130 mm.
The length dimension L2 in the transverse direction X of the urination region 24 is preferably in a range of about 60 to about 170 mm and more preferably in a range of about 85 to about 140 mm.
From the viewpoint of a urine retention capacity, it will be preferable to determine the length dimension L2 in the transverse direction X of the urination region 24 to be relatively large.
However, when the length dimension L2 is excessively large, the lateral portions of the urine receptacle 11 might be put in contact with the wearer's inner thighs. In contrast, if the length dimension L2 is excessively small, it will be difficult to hold the genitalia R stably. Considering these undesirable cases, the length dimension L2 is preferably within the range as described above.
The length dimension L4 in the transverse direction X of the urine receptacle 11 is a sum of the length dimension L2 in the transverse direction X of the urination region 24 and a length dimension two times the total length dimension L5 in the transverse direction X of a pair of the adhesive regions 30e of the backsheet 30.
In the urine disposal device 10 according to the present embodiment put on the wearer in supine posture, the external outlet port (connecting region) 65b of the urine receptacle 11 is arranged on the second surface F not facing the wearer's skin. In consequence, when the wearer discharges excrement, the skin-contact surface of the urine receptacle 11 covers the first connecting tube 12a and the external outlet port 65b, whereby the distal end portion of the first connecting tube 12a and the external outlet port 65b are unlikely to be soiled with the excrement. In addition, the external outlet port 65b is unlikely to come in contact with the wearer's body since the external outlet port 65b is arranged on the second surface F. In this way, it is possible to alleviate a sense of discomfort felt by the wearer even if the urine collecting container 13 is formed of a thermoplastic synthetic resin.
In the state that the urine receptacle 11 is arranged so that the imaginary longitudinal center line Q extends in parallel to the vertical lines M3, M4, the urine collecting container 13 is arranged so that the internal space 64 may be arranged within the overlapping region 90 the internal space 64 of the urine collecting container 13 is arranged within the overlapping region 90 defined so that an angle θ1 formed between the vertical line M3 passing through the center of the high stiffness region 80 on one side in the transverse direction X is 45° or less and an angle θ2 formed between the vertical line M4 passing through the center of the high stiffness region 80 on the other side in the transverse direction X and the second imaginary line M2 is 45° or less. Such arrangement is effective to prevent urine from leaking out through the opening 28 even when the wearer of the urine receptacle 11 is in a lying posture. Furthermore, the urine collecting container 13 is arranged so that the internal space 64 occupies a lower half of the urination region 24 and such arrangement assures that the discharged urine is reliably suctioned.
Furthermore, the urine collecting container 13 is arranged in the urine receptacle 11 in such a manner that the urine evacuation direction A is oriented toward the opening 28. Such arrangement of the urine collecting container 13 makes it possible to arrange the internal outlet port 65 adjacent to the second end edge 11b of the urine receptacle 11, whereby urine is unlikely to remain in the urine receiving space S.
In addition, the high stiffness regions 80 are locally formed as a portion of the periphery 28a of the opening 28 in the course of heat sealing a plurality of sheets 39, 40, 41, 42, 44, 45 and 49 and, more specifically, these high stiffness regions 80 are formed only on the respective lateral edges 30c, 30d in the transverse direction X of the sheets 39, 40, 41, 42, 44, 45 and 49. Consequently, the stiffness in the middle portions in the transverse direction X of these sheets is relatively low and the sheets 39, 40, 41, 42, 44, 45 and 46 are easily bent. In this manner, it is possible to provide the urine receptacle 11 of which the opening 28 may be smoothly opened.
Now functional behaviors of the urine receptacle 11 and the urine disposal device 10 using this urine receptacle 11 will be described. Urine discharged in the urination region 24 of the urine receptacle 11 is temporarily retained within the urine receiving space S defined within the urine receptacle 11. The amount of urine temporarily retained within the urine receiving space S permeates the topsheet 40, the second sheet 41 and the elastic rebound sheet 42 and come in contact with the urine sensor 22. When any amount of urine bridges the electrodes 51, 52 of the urine sensor 22, the urine detection regions 54 detect the presence of urine.
Based on detection by the urine sensor 22, the control unit 17 actuates the vacuum pump 15. In response of actuation of the vacuum pump 15, the urine tank 14 becomes in vacuum state and urine has been retained within the internal space 64 of the urine collecting container 13 is suctioned through the first connecting tube 12a into the urine tank 14 and the urine receiving space S is evacuated. When the urine sensor 22 becomes unable to detect any amount of urine, the control unit 17 ceases to drive the vacuum pump 15 on the basis of non-detection by the urine sensor 22.
The kinds of material for the constituent members of the urine receptacle 11 according to the present invention are not limited to those described in this specification but the other various types of material widely used in the relevant technical field may be used without limitation. The terms “first”, “second” and “third” used in the specification and Claims of the present invention are used merely to distinguish similar elements or similar positions.
For the laminated sheet structure 29, it is not essential to use all of the sheets 39, 40, 41, 42, 44, 45 and 49 but it is possible for any purpose to leave off one or more from these sheets 39, 40, 41, 42, 44, 45 and 49. It is also possible to add any other kinds of sheets to these sheets as necessary.
While the embodiment according to which the adhesive regions 30e are formed over the entire upper surface of the backsheet 30 has been described, it is not essential to form such adhesive regions 30e over the entire area but it is also possible to form the adhesive regions 30e only in regions requiring them and to leave non-adhesive regions.
While the embodiment according to which only the protection sheet 39 is provided for the purpose of protecting the topsheet 40 only has been described, it is possible to provide also a protection sheet to protect the leakage-barrier sheet 48.
The urine receptacle 11 may be assembled by following other steps of assembling different from the steps of assembling as has been described above.
While the embodiment according to which the leakage-barrier sheets 48 are not included in the sheets which are heat sealed together to form the high stiffness regions 80 has been described, the sheets including also the leakage-barrier sheets 48 may be heat sealed together to improve stiffness of the high stiffness regions 80, whereby the opening 28 may be more smoothly opened.
While the stiffness regions 80 have been described to have the circular shapes, the shape of the high stiffness regions 80 may be arbitrarily selected and, for example, the stiffness regions 80 may have polygonal shapes.
Now the urine receptacle 111 in the urine disposal device according to another embodiment of the present invention will be described hereunder. In this regard, the same constituents of the urine receptacle 11 as those in the embodiment described above are designated by the same reference numerals or signs to avoid repetitive explanation.
In the urine receptacle 111 according to this embodiment, the urine collecting container 113 is arranged within the urine receptacle 111 so that the urine evacuation direction A from the internal outlet port 65a to the external outlet port 65b is not oriented to the opening 28 but reversely oriented. The urine collecting container 113 is arranged on the second surface F of the urine receptacle 111 for the wearer in a supine posture.
In this urine receptacle 111, the urine collecting container 113 is arranged within the urine receptacle so that the urine evacuation direction A may be not oriented toward the opening but reversely oriented and consequently it is possible to arrange the external outlet port 65b functioning also as the connecting region adjacent to the second end edge 11b of the urine receptacle 111, thereby facilitating the connector 12 to be connected with the external outlet port 65b.
