Description

  The present invention relates to a pelvic floor sensory bearing surface structure, a pelvic floor sensory cushion, and a pelvic floor sensory chair for perceiving the pelvic floor.

  The pelvic floor is a portion formed by muscles and fibrous tissues that support organs such as the bladder, urethra, uterus and rectum from the bottom inside the pelvis. The pelvic floor shrinks by going on at the time of childbirth, but the birth canal also shrinks and tends to be difficult to produce. Therefore, if this pelvic floor can be loosened consciously, childbirth can be performed relatively easily. However, in order to loosen the pelvic floor, it is necessary to perceive and be aware of the pelvic floor, which is not easy for those who have never been aware of the pelvic floor.

On the other hand, there are devices for training pelvic floor muscles for the treatment of stress urinary incontinence and the like. This device includes a measurement unit having an insertion part that can be inserted into the anus and rectum, and a connection part that detachably connects the measurement part and the processing / display unit, and measures the pressure of the insertion part. It is displayed (see, for example, Patent Document 1). According to this device, the muscles of the pelvic floor can be effectively trained, and at the same time, the pelvic floor can be perceived.

  The device described above is an effective device for improving the muscular strength of the pelvic floor, but it is an expensive device to own and use and requires some preparation for use. .

  Accordingly, an object of the present invention is to provide a simpler and cheaper means mainly for the perception of the pelvic floor.

  According to the present invention, a base seat surface (3) is projected from the base seat surface (3) along a central axis (C) extending in the front-rear direction of the base seat surface (3), and the base seat surface (3) The above problem is solved by providing a pelvic floor sensory bearing surface structure (1) provided with a raised surface (11) protruding forward.

  When sitting on the seat surface having this pelvic floor perceived seat surface structure with the raised surface sandwiched between the crotch, the raised surface protrudes forward, so the leg can be lowered while straddling the raised surface. . Since the raised surface is higher than the base seat surface, an appropriate contact pressure is applied to the pelvic floor by the raised surface. In this state, it is possible to grasp the sensation of applying force to the pelvic floor by applying force to an conscious place such as the anus. By repeating this, the pelvic floor can be gradually perceived.

  Further, the present invention provides a plate-like cushion having a base seat part (4) including a base seat surface (3) on the upper surface and a projecting part (5) projecting forward from the center part of the front edge of the base seat part (4). (6) and having an elongated chevron shape, with one end (9) placed on the protrusion and the other end (10) on the base seat (4) along the central axis (C). A mountain-shaped cushion (7) forming the raised surface (11) by being disposed, and a horizontal cross section of the plate-like cushion (6) attached to the lower surface of the plate-like cushion (6). The above object is achieved by providing a pelvic floor sensory cushion (2) having a pelvic floor sensory bearing surface structure.

  When sitting on this pelvic floor perception cushion with the raised surface sandwiched between the crotch, the raised portion protrudes forward, so that the leg can be lowered while straddling the raised surface. Since the raised surface is higher than the base seat surface, an appropriate contact pressure is applied to the pelvic floor by the raised surface. In this state, it is possible to grasp the sensation of applying force to the pelvic floor by applying force to an area such as the anus that can be conscious, and by repeating this, it becomes possible to gradually perceive the pelvic floor. Further, since the pelvic floor sensory bearing surface structure is provided in the form of a pelvic floor sensory cushion, it can be easily used on a chair or sofa at home. Further, since the bottom plate is provided, the shape of the pelvic floor sensory cushion is prevented from being deformed by the shape and flexibility of the chair or sofa on which the pelvic floor sensory cushion is placed. The pressure applied to the pelvic floor is prevented from changing.

  The bottom plate (12) may be provided with two holes (30) on the left and right with respect to the central axis. According to this, when sitting on this pelvic floor perception cushion, the left and right sciatic nodules sink into this hole, and it is possible to give a more appropriate contact pressure to the pelvic floor due to the synergistic effect with the mountain shaped cushion .

  The side and upper portions of the plate-like cushion (6), the mountain-shaped cushion (7) and the bottom plate (12) are formed of a material softer than the material of the plate-shaped cushion (6) and the mountain-shaped cushion (7). You may enclose by the outer packaging material (13) made. According to this, since the unevenness | corrugation of the whole of a plate-shaped cushion and a mountain-shaped cushion is relieve | moderated with an outer packaging material, more favorable seating comfort can be obtained. Further, since the outer packaging material is more flexible than the plate-like cushion or the mountain-shaped cushion, the effect of the raised surface formed by the mountain-shaped cushion on the pelvis bottom is not reduced.

  In the pelvic floor sensory cushion (2), a portion covering the outer side of the outer packaging material (13) is made of the first material (14a), and a portion covering the back surface of the bottom plate (12) is more stretchable than the first material. It may be covered by a cover (14) made of a second material (14b) with low properties. According to this, since the entire pelvic floor perception cushion is covered with the cover, each member can be protected and the appearance can be decorated. Further, since the second material covering the back surface of the bottom plate has low elasticity, the first pelvic floor sensory cushion of the present invention is relatively difficult to be displaced even when placed on a chair or sofa, and the first material covering the outside of the outer packaging material. Due to the high elasticity of the material, the seat extends comfortably according to the shape of the seating surface when sitting down.

  Moreover, the above-mentioned pelvic floor sensory seating surface structure (1) or pelvic floor sensory cushion (2) can also be provided in the form of a pelvic floor sensory chair having this in the seat. In this case, use becomes easier.

  In addition, in the above description, in order to make an understanding of this invention easy, the reference sign of the accompanying drawing was attached in parenthesis, but this invention is not limited to the form of illustration by it.

  Since the pelvic floor perception seat structure, the pelvic floor perception cushion, and the pelvic floor perception chair of the present invention have a simple configuration as described above, they can be manufactured at low cost. Moreover, it becomes possible to perceive the pelvic floor simply by sitting. And when the pelvic floor can be perceived, the pelvic floor can be consciously loosened even when the birth canal tends to contract during birth, making it easier to spread the birth canal. It can lead to medically healthy childbirth. Furthermore, by perceiving the pelvic floor, pelvic floor training for healing stress urinary incontinence caused by loosening of the lower abdomen due to childbirth and experience of childbirth and drooping of the bladder can be easily performed.

  1 is a top view of a pelvic floor sensory cushion having a pelvic floor sensory bearing surface structure according to one embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1, and FIG. FIG. 4 is a cross-sectional view taken along line III-III, and FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. In this specification, when the user sits on the pelvic floor sensory cushion of the present invention, the direction in which the user faces is the front, and the direction in which the user is facing is the rear.

  As shown in the drawing, the pelvic floor sensory cushion 2 having the pelvic floor sensory seating surface structure 1 of the present embodiment includes a base seat part 4 whose upper surface forms a base seating surface 3 and a front edge of the base seat part 4 forward. A plate-like cushion 6 having a protruding portion 5 that protrudes is provided. Further, a chevron cushion 7 is stuck on the plate-like cushion 6. The chevron cushion 7 has an elongated chevron shape, and one end 9 of the bottom surface 8 has the same contour as the protruding portion 5, and the width of the other end 10 of the bottom surface 8 is narrower than the width of the one end 9. Then, the angle cushion 7 is disposed along the central axis C of the base seat surface 3 with one end 9 placed on the protruding portion 5 and the other end 10 placed on the center portion of the base seat portion 4. A raised surface 11 is formed that protrudes forward from the front edge of the surface 3 and rises upward, with the rear end of the raised portion extending beyond the front edge and into the base seat surface. As shown in FIGS. 2 to 4, a bottom plate 12 is attached to the lower surface of the plate-like cushion 6, and the side and upper surfaces of the plate-like cushion 6 and the mountain-shaped cushion 7 excluding the bottom surface of the bottom plate 12 are outer packaging materials. 13 and is further covered from above with a cover 14 including the bottom surface of the bottom plate 12.

  The plate-like cushion 6 is formed by molding a foamed urethane chip and has a certain thickness. The base seat portion 4 which is a part of the plate cushion 6 has a substantially rectangular shape. Then, the side surface extends to the left and right in the rear to form the rear side surface 20 as shown in FIGS. 1 and 2, and both ends of the rear side surface 20 bend forward about 90 ° along an arc of a predetermined radius. As shown in FIGS. 1 and 4, left and right side surfaces 21 perpendicular to the rear side surface 20 are formed. Further, the front ends of the left and right side surfaces 21 bend inward along a circular arc with a predetermined radius to form the front side surface 22 as shown in FIG. 1, but the front side surface 22 is not perpendicular to the left and right side surfaces 21, but is somewhat Looking forward. The front side surface 22 protrudes further forward along a circular arc of a predetermined radius at a position that is a predetermined distance from the central axis C of the plate-like cushion 6, and after extending a certain distance, its end is The front side surfaces 22 smoothly extending toward the central axis C and extending from the left and right are connected. And the part which protruded ahead forms the protrusion part 5 which protrudes ahead from the front edge part of the base seat surface 3. FIG.

  Here, in this embodiment, the distance between the left and right side surfaces of the base seat surface 3 is about 390 mm, and the distance between the rear side surface 20 and the tip of the protruding portion 5 is about 350 mm. Further, the position where the left and right side surfaces 21 bend inward is a position of about 169 mm from the rear side surface 20, and the predetermined distance from the central axis C where the front side surface 22 faces forward is about 65 mm. Each of these lengths is a length in a state in which the outer packaging material 13 is not included, and is a value determined to be optimal as a result of using several types of pelvic floor perception cushions by several monitors. However, it is not limited to these values, and for example, the optimum value varies depending on the nationality and age of the user.

  The mountain-shaped cushion 7 disposed on the plate-like cushion 6 is also formed by molding the same foamed urethane chip as the plate-like cushion 6. Further, as shown in FIG. 2, the cross section in the longitudinal direction of the chevron cushion 7 has a shape in which the upper two corners of the elongated rectangular shape are rounded with a predetermined radius, and the front height is slightly higher than the rear height. . Thus, the reason why the front height is made higher than the rear is to prevent slipping down when sitting on the pelvic floor sensory cushion 2. Moreover, since the use of a pregnant woman can be considered, it is also for reducing anxiety of sliding down. As shown in FIGS. 3 and 4, the cross section in the short direction has a shape in which two corners of the upper part of the rectangle are rounded with a predetermined radius.

  Here, in this embodiment, the mountain cushion 7 has a length of about 216 mm, a maximum height of about 40 mm, a minimum height of about 35 mm, and a maximum width of 130 mm. These values are also values determined to be optimal by monitoring in the same manner as the above-described plate-like cushion 6, but are not limited to this, and vary depending on, for example, the nationality and age of the user.

  The bottom plate 12 disposed under the plate-like cushion 6 has substantially the same shape as the horizontal cross section of the plate-like cushion 6, and when the pelvic floor perception cushion 2 of this embodiment is placed on a home chair, sofa or the like. In addition, the pelvic floor sensory cushion 2 is made of a material such as plywood that is stiff to some extent so as not to be deformed. The bottom plate 12 is provided with two long holes 30 in parallel at an equal distance from the central axis C of the plate cushion 6 as shown in the figure. The long hole 30 has a shape in which a semicircle having a diameter of 40 mm is joined to a front and rear of a rectangle 60 mm in the left and right and 80 mm in the front and rear, and the distance between the centers of both is about 144 mm. This 144 mm is determined from the distance between the left and right points with the highest pressure by having the monitor sit on the seat with pressure sensitive paper and gently pedaling for 5 minutes. This distance corresponds to the distance between the sciatic nodules, and the actual measurement value is 120 to 140 mm. However, since a slightly larger value than this value feels comfortable, the distance between the centers of the long holes was set to 144 mm. The thickness of the bottom plate 12 is about 9 mm. And the part in which the long hole 30 was provided is chamfered so that it may not hurt when it contacts a collar part, and the angle | corner is round. In addition, these values are not limited to this, For example, it changes with the nationality, age, etc. of a user.

  The outer packaging material 13 that covers the side and upper portions of the plate-shaped cushion 6, the mountain-shaped cushion 7, and the bottom plate 12 is formed of a urethane material that is more flexible than the urethane foam chip that is the material of the plate-shaped cushion 6 and the mountain-shaped cushion 7. The outer packaging material 13 has a side surface thickness of about 8 mm and an upper surface thickness of about 11.5 mm. The outer packaging material 13 extends substantially linearly from the top of the mountain cushion 7 to the corner of the plate cushion 6, and there is a gap between the upper surface of the plate cushion 6 and the outer packaging material 13. To do.

  Further, the cover 14 that covers the entire outer surface of the outer packaging material 13 including the bottom surface of the bottom plate 12 is compared with the first material 14 a that covers the periphery of the outer packaging material 13 and the first material 14 a that covers the back surface of the bottom plate 12. And made of the second material 14b having low elasticity. The reason why the first material 14a having high elasticity is used around the outer packaging material 13 is to obtain a good fit when sitting, and the second material having low elasticity at the bottom of the bottom plate 12 is used. The material 14b is used to prevent slipping when sitting.

  Next, the usage method will be described. First, the pelvic floor sensory cushion 2 of this embodiment is placed on a chair or sofa, and the raised surface 11 is placed between the crotch. In this case, since the front height of the mountain-shaped cushion 7 is slightly higher than the rear height, when sitting on the pelvic floor sensory cushion 2 of this embodiment, it is prevented from slipping down, and the anxiety of sliding down can be reduced. Yes, especially when used by pregnant women. The upper body is inclined slightly forward. In this case, since the protruding portion protrudes from the base seat portion 4 and the other portion is constricted, the leg can be lowered. In addition, since two long holes 30 are provided in the bottom plate 12 with a center-to-center distance of 144 mm, a sciatic nodule just fits into the long hole 30 and the sciatic nodule does not hit the bottom plate 12 and is painful even if used. Absent. When the force is released in this state, an appropriate contact pressure is applied to the pelvic floor by the raised surface 11. And by putting power in areas where you can be conscious, such as the anus, the feeling of putting power into the pelvic floor will be perceived. By repeating this for about 20 minutes a day, it is possible to gradually perceive the location of the pelvic floor even when not sitting on the pelvic floor perception cushion 2.

  As mentioned above, since the pelvic floor perception cushion of this form is a simple structure as mentioned above, it can be manufactured cheaply. Moreover, it becomes possible to perceive the pelvic floor simply by sitting. Then, even when the birth canal tends to contract during birth, the pelvic floor can be loosened consciously. And it can make the birthway easier to spread, and can lead to a medically healthy birth. Furthermore, perception of the pelvic floor facilitates pelvic floor training to cure stress urinary incontinence caused by slack in the lower abdomen due to childbirth and birth experience experienced by a widow or childbirth.

  In addition, this invention may be implemented with a various form, without being limited to the form mentioned above. For example, the present embodiment has been described as a form of a pelvic floor sensory cushion used by placing it on a chair or sofa, but is not limited thereto, and is a form of a chair having the pelvic floor sensory seating surface structure. May be. In this case, the chair may have any form, but when the stool type with one chair leg is seated, the user's leg does not hit and is easy to use. Moreover, it is preferable that the height of the leg of the chair can be adjusted so that it can be used according to the length of the leg of the user.
