JP-T-2001-501116 Japanese translation of PCT publication No. 2002-512841 Japanese Patent No. 3302687

  The devices of Patent Documents 1 to 3 are all mounted on the penis, have a sense of incongruity, and have to use care in adjusting the pressure when mounting, and have problems in terms of ease of mounting. . Further, during normal urination, an operation of relaxing the pressure is necessary, but in any case, an operation of relaxing in the circumferential direction of the penis is necessary and is troublesome.

  The present invention has been made in view of the above, a male urinary incontinence prevention device that can be worn very easily and comfortably without discomfort, and urinary incontinence using the male urinary incontinence prevention device It is an object to provide a prevention method.

  In order to solve the above-described problems, a male urinary incontinence prevention device according to the present invention includes a pressing member, a holding member for holding the pressing member, and mounting the perineal portion of the wearer so that the perineal portion is pressed by the pressing member. It is characterized by having.

  The pressing member preferably has a shape having a substantially arc-shaped section that bulges toward the perineum when the holding member is mounted. The pressing member preferably has a predetermined length in the front-rear direction along the perineum and is capable of pressing the perineum in a range corresponding to the length. In the pressing member, a groove facing the front-rear direction can be formed on the surface facing the perineum. The pressing member preferably includes an elastic body and a cover member that covers the elastic body. It is preferable that the elastic body and the cover member have a structure in which at least a part thereof facing each other is not fixed so that at least a part of the cover member can be displaced with respect to the elastic body. The holding member includes a holding portion that holds the pressing member, and includes a front support portion that extends forward across the holding portion and a rear support portion that extends rearward across the holding portion. It is preferable that

  Further, the urinary incontinence prevention method of the present invention is equipped with a male urinary incontinence prevention device having a pressing member and a holding member for holding the pressing member so that the perineal part of the wearer is pressed by the pressing member. By doing so, the vicinity of the bulbous urethra is narrowed to prevent urinary incontinence.

  According to the present invention, the pressing member held by the holding member is provided, and the wearer presses the perineum with the pressing member by attaching the holding member to the body. When the perineum is pressed, the vicinity of the bulbous urethra is pressed from below. Thereby, the urethra, especially the bulbous urethra is narrowed, and urine leakage can be suppressed.

  In addition, the pressing member has a predetermined length in the front-rear direction along the perineum, and preferably has a groove in the length direction, thereby increasing the contact area with the perineum, Since the area where the urethra including the urethra is pressed is increased, the effect of suppressing urine leakage is further enhanced. In particular, during prostatectomy, urination disorder is likely to occur due to nerve damage.According to the present invention, by pressing the perineum with a pressing member, movement of the organ during prostatectomy is suppressed, and further, deformation of the perineum Since it is easy to fit (easy to follow and easy to follow), the effect of suppressing urine leakage is high, and it is very effective at the time of prostatectomy.

  Further, by adopting a structure including an elastic body as the pressing member, it is possible to urinate during normal urination without weakening the pressing force by the pressing member due to the pressure. Further, even when it is necessary to weaken the pressing force by the pressing member, it is only necessary to slightly lower the position of the holding member, and handling during urination is easier compared to the conventional one.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. The male urinary incontinence prevention device 1 according to the present embodiment includes a pressing member 10 and a holding member 20 as shown in FIGS. 1 and 2.

  When the wearer wears the holding member 20, the pressing member 10 comes into contact with the perineum of the wearer (a portion between the scrotum and the anus) and presses the perineum. The configuration of the pressing member 10 is not limited as long as the pressing member 10 performs such a function. By pressing the perineum with the pressing member 10, a sphere present in the vicinity corresponding to the perineum, particularly the perineum. It is necessary to have a pressing force that can narrow the urethra.

  Therefore, as shown in FIG. 3, the pressing member 10 preferably has an elastic body 11 made of a foamed resin or the like having excellent elasticity such as urethane foam. As shown in FIG. 4, the elastic body 11 of the present embodiment is provided with at least part of a substantially arc-shaped section 11a in cross section, for example, approximately semicircular or semielliptical, It is formed in such a shape that a certain direction) goes to the perineum. For example, the elastic body 11 may be solid with a substantially hemispherical cross section, but as illustrated in FIG. 4, a shape having a hollow portion 11 b having a predetermined semicircular cross section with a predetermined size from the bottom surface side. It is preferable to form by. The elasticity of the elastic body 11 can be adjusted by the thickness of the elastic body 11 and the size of the cut-out portion 11b. Further, the elastic body 11 is not limited to a substantially semicircular or semi-elliptical section, but may be formed from a substantially rectangular parallelepiped, a substantially convex section, or another solid body. However, as shown in FIG. 4, it is preferable to have a shape having a substantially arcuate section 11 a because the feeling of discomfort at the time of contact with the perineum is small and a pressing force is easily applied to the spherical urethra inside the perineum.

  The pressing member 10 preferably has a configuration in which the surface of the elastic body 11 is covered with the cover member 12. The cover member 12 is provided to suppress rubbing when coming into contact with the perineum, and is preferably made of a material having flexibility, a material made of a thermosetting elastomer or a thermoplastic elastomer, such as a soft silicone rubber. . The thickness is preferably about 0.5 to 2 mm. The degree of flexibility is 0 to 80 degrees, preferably 5 to 50 degrees, and more preferably 10 to 40 degrees according to a type A durometer defined in JIS K6253.

  The cover member 12 covers the surface of the elastic body 11, and is provided so that at least a part of the peripheral edge portion 12a is joined to the bottom surface of the elastic body 11 (see FIGS. 3D and 3E). It is preferable that at least a part of the opposing portions of the elastic body 11 is not fixed. Thereby, at least a part of the cover member 12 that is not fixed can be displaced with respect to the elastic body 11. Therefore, even when the frictional force between the cover member 12 and the wearer's skin or underwear increases due to, for example, the wearer's perspiration, the cover member 12 is displaced, thereby reducing the uncomfortable feeling during wearing.

  Here, the shape of the pressing member 10, that is, the shape of the elastic body 11 and the cover member 12 constituting the pressing member 10 is indicated by a predetermined length in the front-rear direction along the perineum (reference symbol L in FIG. 3A). It is preferable to have a length in the other direction. That is, it is preferably formed in a substantially elliptical shape, a substantially rectangular shape or the like in plan view. Since the men's perineum has a predetermined length in the front-rear direction, the pressing area of the perineum is widened by forming a shape along it. As a result, the area where the urethra present in the perineum, particularly the bulbous urethra, is pressed is expanded, the urethra is more reliably blocked, and the effect of suppressing urine leakage is enhanced. On the other hand, if the width is too wide in the lateral direction, a sense of incongruity due to contact with the vicinity of the inner side of the thigh is increased, and therefore, the shape is preferably long in the front-rear direction.

  Moreover, as shown in FIG. 5, it can also be set as the shape by which the groove part 10a along the front-back direction was formed in the surface facing the perineum part in the press member 10. As shown in FIG. In this embodiment, since the pressing member 10 is provided with the elastic body 11 and the cover member 12, as shown in FIG.5 (c), the elastic body 11 is made into the front-back direction (length direction) in the top part. A structure in which the groove 11c is formed is formed. If the groove portion 11c is formed in the elastic body 11, the cover member 12 covers the surface thereof. Therefore, the cover member 12 has a shape along the groove portion 11c, so that FIGS. As shown in FIG. 5, the groove 10 a is formed in the pressing member 10. At the time of pressing, the groove portion 10a is pressed so as to expand, so that it is easy to fit in a larger area in the perineum.

  The pressing member 10 includes an elastic body 11 and a cover member 12, but in the present embodiment, a bottom support cover 13 is further provided on the bottom surface side of the elastic body 11. As shown in FIGS. 3 and 6, the bottom support cover 13 has a bulging portion 13 a at a substantially central portion in the present embodiment. The bulging portion 13a is formed to have a size enough to be inserted into the cutout portion 11b of the elastic body 11. By having the bottom support cover 13, when the cover member 12 is pressed, the elastic body 11 is prevented from being crushed and a predetermined pressing force can be exerted. In order to achieve the function of the bottom support cover 13, the bottom support cover 13 is preferably molded from a resin that is harder than the cover member 12. It is preferable to comprise a thermosetting elastomer or a thermoplastic elastomer having a hardness of 30 to 80 degrees as measured by a type A durometer defined in JIS K6253.

  As described above, the cover member 12 is preferably provided so as to cover the surface of the elastic body 11 and at least a part of the peripheral edge portion 12a is joined to the bottom surface of the elastic body 11, but the bottom support cover 13 is provided. In this case, it is preferable to fix the peripheral edge portion 12a of the cover member 12 turned to the bottom surface side of the elastic body 11 to the bottom portion support cover 13 (see FIGS. 3D and 3E). In this case, since the elastic body 11 is sealed between the cover member 12 and the bottom support cover 13, the bottom support cover 13 is preferably provided with an air vent hole 13 b. By using the air vents 13a having different diameters, it is possible to change the stretch response of the elastic body 11 and to provide a pressing force suitable for the wearer. It is also possible to provide a variable mechanism for changing the size of the air vent hole 13a (for example, a lid member for opening and closing the air vent hole 13a in the sliding direction) and adjusting the pressing force by changing the air vent hole 13a. It is.

  As shown in FIGS. 1 and 2, the holding member 20 includes a holding portion 21 that holds the pressing member 10, and includes a front support portion 22 and a rear support portion 23 with the holding portion 21 interposed therebetween. The holding part 21 is a part to which the pressing member 10 is fixed, for example, by sewing. In the present embodiment, it is formed in a substantially X shape in plan view, and the intersection is the holding portion 21. In order to easily fix the pressing member 10 to the holding portion 21, the cover member 12 and the bottom support cover 13 are preferably formed so as to have a flange portion 14 protruding in a direction corresponding to the front and rear of the perineum portion. If the flange portion 14 is stitched to the holding portion 21, the pressing member 10 can be easily fixed to the holding portion 21. The fixing means is arbitrary, and is not limited to stitching, but may be adhesion, welding, or the like. Further, the back surface of the pressing member 10 may be adhered and fixed without forming the flange portion 14.

  The two front sides sandwiching the holding unit 21 are front support units 22 and 22, and the two rear sides sandwiching the holding unit 21 are rear support units 23 and 23.

  The front support portions 22 and 22 and the rear support portions 23 and 23 are limited in structure as long as they are mounted so that the pressing member 10 held by the holding portion 21 can be pressed against the perineum. is not. For example, the front support portions 22 and 22 and the rear support portions 23 and 23 are held by the wearer while being pulled in the upper body direction of the wearer. In the present embodiment, the front support portions 22 and 22 and the rear support portions 23 and 23 have fixing portions 22a and 23a formed with hook-and-loop fasteners. And it joins and connects with the surface located in the front side of the to-be-attached member 30 shown in FIG. 7 attached to a wearer's waist circumference vicinity (refer FIG.8 and FIG.9). It should be noted that a hook-and-loop fastener 30a is provided near one end of one surface of the attached member 30, and after being wound around the waist portion, these are joined to the opposite surface side of the attached member 30 so as to be attached near the waist portion. It has become. Accordingly, when the front support portions 22 and 22 and the rear support portions 23 and 23 are pulled up and the fixing portions 22a and 23a are fixed with respect to the attached member 30 worn by the wearer around the waist, they are halfway. The pressing member 10 held by the holding portion 21 presses the perineum. Note that the fixing method of the fixing portions 22a and 23a and the attached member 30 is arbitrary, and a structure of a buckle portion of the belt may be adopted in addition to using a hook-and-loop fastener.

  The front support portion 22 and the rear support portion 23 are portions that extend across the holding portion 21 that holds the pressing member 10 and may be any structure that can be supported by the wearer at a predetermined position. Accordingly, each of the front support portion 22 and the rear support portion 23 may be one instead of two, or may be three or more. Moreover, even if the holding member 20 is a pants-type, the perineum part equivalent part becomes the said holding part 21, the front body part is a front support part, the back body part is a back support part, etc. In this case, the attached member 30 is unnecessary. However, by combining the male urinary incontinence prevention device 1 and the attached member 30 of this embodiment, the male urinary incontinence prevention device 1 can be easily adjusted in the attachment position to the attached member 30 and attached. Since the member 30 is also wound around the waist and attached, there is an advantage that adjustment of the winding position is easy and the body type difference of the wearer can be absorbed by the adjustment. Therefore, it is preferable to provide the male urinary incontinence prevention device 1 and the attached member 30 according to the present embodiment in combination as a male urinary incontinence prevention set.

  When using the male urinary incontinence prevention device 1 of this embodiment, as shown in FIGS. 8 and 9, first, the attached member 30 used in combination with the male urinary incontinence prevention device 1 is used. Install around the waist. Then, in a state where the pressing member 10 is fixed to the holding portion 21, the fixing portions 22 a and 23 a of the front support portions 22 and 22 and the rear support portions 23 and 23 are connected to the attached member 30. At this time, the wearer wears the pressing member 10 while aligning so that the pressing member 10 corresponds to the perineum. However, the wearer may attach the underwear while wearing the underwear, or may wear the body without wearing the underwear. You may attach directly to.

  At the time of mounting, the front support portions 22 and 22 and the rear support portion 23 with respect to the attached member 30 are set so that the force for pressing the perineum by the pressing member 10 is moderate and can prevent urine leakage. The joining positions of the 23 fixing portions 22a and 23a are adjusted. When attached to a desired position, the pressing member 10 presses the perineum, and as a result, the urethra, particularly the vicinity of the bulbous urethra, is compressed, so that the urethra at the site is narrowed. Thereby, leakage of urine in the urethra and bladder can be prevented.

  The male urinary incontinence prevention device 1 of the present embodiment may be worn through the underwear as described above, or may be worn so as to directly contact the skin without using the underwear. By sweating, the cover member 12 can easily adhere to the perineum. However, at this time, according to the present embodiment, since at least a part of the cover member 12 and the elastic body 11 are not joined to each other, the flexible cover member 12 moves independently following the movement of the perineum. There is an advantage that there is little discomfort.

In the male urinary incontinence prevention device 1 of the present embodiment using the pressing member 10 shown in FIG. 3, the urination function is lowered by prostatectomy, and most of the urine is not attached to the male urinary incontinence prevention device 1. An experiment was conducted on 10 male subjects who were leaking. In the experiment, the male urinary incontinence prevention device 1 of this embodiment is mounted on the pants so that the pressing member 10 abuts on the perineum, and a urine leak pad (weight 40 g) is applied in the pants to urinate. The amount of urination at the time and the amount of leakage of urine leaked from the urine leakage pad at that time (leakage amount) were measured. Therefore, the amount of urine per time is the total amount of urination and leakage. The urine leakage pad was changed every time urination was performed, and the experiment was conducted for 7 consecutive days and was also worn at bedtime.
The following table shows data for each measurement day from a certain subject A's getting up to bedtime.

  As described above, when the male urinary incontinence prevention device 1 of the present embodiment is not worn, most of the urine volume becomes a leakage amount, but by wearing the male urinary incontinence prevention device 1 of the present embodiment. When the 4th day is excluded, it turns out that it will be about 1/3 to 1/10 with respect to the amount of urine. According to this test subject A's comment, the obstacle to going out was greatly reduced.

  Moreover, the data (measurement amount at the time of waking up) from bedtime to waking up on each measurement day of the subject A were as shown in the following table.

  According to the subject A, it was that sleep was often hindered by urine leakage during bedtime before wearing, but by wearing the male urinary incontinence prevention device 1 of this embodiment, The amount of leakage from bedtime to getting up was almost eliminated, the number of urinations during bedtime was reduced, and sufficient sleep could be obtained.

  In addition, the other subjects also had almost the same results as those of the subject A, and the leakage amount with respect to the urine amount from getting up to bedtime decreased to about 1/3 to 1/10. Urinary leakage from bedtime to waking up was greatly reduced, and the number of urinations during bedtime was reduced, making it possible to secure comfortable sleep.

  Moreover, when the urination is performed by lowering the attachment positions of the front support portions 22 and 22 and the rear support portions 23 and 23 of the holding member 20, the urination sensation is similar to that at the time of health. There were many impressions that the operation of lowering the mounting positions of the rear support portions 22 and the rear support portions 23 was also easy.

  In addition, when one of the subjects described above was tested with the male urinary incontinence prevention device 1 using the pressing member 10 having the groove 10a shown in FIG. However, when urinating, a certain amount of urination could be achieved without pressing down the male urinary incontinence prevention device 1 by applying force to the lower abdomen. In order to urinate reliably, the male urinary incontinence prevention device 1 must still be pushed down, but the configuration with the groove 10a can improve the balance between preventing urine leakage and urinating as worn. Sex was found.

  The male urinary incontinence prevention device 1 of the present invention is prepared in case of urine leakage, for example, by extending the holding portion 21 of the holding member 20 forward, and attaching a urine leakage pad or a urine storage bag to the site. It is also possible to adopt a configuration. In this case, the urine leakage pad having a predetermined area may be held by the holding member 20 and the pressing member 10 may be held on the inner surface of the urine leakage pad. In addition, the material itself of the holding member 20 can be made of a material having high water absorption. Furthermore, it is possible to form at least the cover member 12 from a material having high water absorption among the elastic body 11, the cover member 12, and the bottom support cover 13 constituting the pressing member 10. In this case, however, it is needless to say that the cover member 12 preferably has the flexibility in the above-described range.

  Moreover, the structure which consists only of the elastic body 11 shape | molded from the foaming resin etc., such as urethane foam, may be sufficient as the press member 10. FIG. In this case, it may be a solid structure such as a substantially hemispherical shape, or may be a structure having a cut-out portion from the bottom side as in the above embodiment. In any case, a structure having a predetermined elasticity, preferably one that can exhibit a predetermined pressing force while exhibiting a soft spring characteristic at the initial stage of deformation when pressed from the upper side on the side in contact with the human body. I just need it. The bottom support cover 13 described above is used as a core member for causing the elastic body 11 to exhibit predetermined elasticity. The bottom support cover 13 and the elastic body 11 are combined to have a cover member 12. The structure may be omitted. Further, the core member is not limited to the shape of the bottom support cover 13 shown in FIG. 6, and a spherical or hemispherical member can also be used. When the core member and the elastic body 11 are integrated, a separately molded core member may be integrated with the elastic body 11 by bonding or sewing, or when the elastic body 11 is molded, it is integrated with the core member. You may make it shape | mold.
