Abstract
Description
Technical Field
[0001] The present invention relates to a pelvic supporter that is fixed around the waist of a user for the treatment and prevention of pelvic pain.
Background Art
[0002] Generally, the pelvis is formed from the sacrum, which is located at the center of the buttocks and has a roughly inverted triangular shape, and the ilium, which is located on the left and right so as to sandwich the sacrum and has an ear-like shape. The part corresponding to the joint is called the sacroiliac joint. This sacroiliac joint is covered with multiple layers of tough ligaments and absorbs or disperses the impact from the upper and lower body. And due to any cause such as mid-back work, sudden movements, childbirth, or a decrease in the muscle strength around the hip joint, making it impossible to support the trunk with muscle strength, a load is applied to the sacroiliac joint, and when inflammation occurs in this sacroiliac joint and pain is generated, it becomes a disease called sacroiliac joint disorder. Specifically, symptoms such as pain in the upper part of the coccyx, pain at the base of the buttocks, pain when bending forward, and pain around the buttocks after childbirth can be seen.
[0003] In order to treat the pelvic pain caused by such sacroiliac joint disorder, various treatments are known. Among them, there is a conservative treatment in which the surrounding of the pelvis is covered with a supporter or a corset to fix or correct the pelvis. For example, in Patent Document 1, in a belt wound around the pelvic part of the waist of the human body, a belt having elasticity is extended from both sides of a flexible pad-shaped substrate that abuts on the lower abdomen. These belts are configured to surround the pelvis around the waist in a state where the belts cross each other in an X shape at the sacroiliac joint part on the back of the pelvis in the extended state and reach the above-mentioned substrate whose tip is located in the lower abdomen. And a sacrum correction belt provided with engaging members for engaging each other at an arbitrary position is disclosed on the substrate and the belt.

[0004] [Patent Document 1] Utility Model Registration No. 3098217 Gazette [Overview of the Initiative] [Problems that the invention aims to solve]
[0005] However, in the sacral correction belt described in Patent Document 1, the belt is crossed at the sacroiliac joint, which creates an effect of tightening the sacroiliac joint inward from both sides, attempting to correct the sacrum to a central position. However, this can actually put a load on the sacroiliac joint by applying inward force, which may cause inflammation and pain. Furthermore, if sacroiliac joint dysfunction is already present, the symptoms may worsen.
[0006] Therefore, the present invention has been made in view of the above problems, and aims to provide a pelvic support that can alleviate symptoms and provide conservative treatment for users who have sacroiliac joint dysfunction, in order to treat and prevent pelvic pain. [Means for solving the problem]
[0007] [1] That is, the pelvic support disclosed in this application comprises a pelvic support portion (1) that supports the posterior side of the user's pelvis, a pair of abdominal band portions (2) that cover the user's abdomen and are detachable from each other, and a pair of adjustment belts (3) that are inserted through through holes (11a) drilled on each side of the pelvic support portion (1), fixed to the abdominal band portion (2) at one end and having a locking portion (31) at the other end, wherein the pelvic support portion (1) comprises both sides (11) made of a hard material through which the through holes (11a) are drilled, and an expandable portion (12) disposed between the two sides (11) that is softer than the two sides (11) and expandable in the direction of the user's waist.
[0008] [2] The pelvic supporter according to [1], characterized in that the pelvic support portion (1) is provided with a core material (13) made of a harder material than the expandable portion and arranged vertically between the two sides (11) so as to be long in the vertical direction along the longitudinal direction of the user's sacrum, and the expandable portion (12) comprises a first expandable portion (121) arranged between one of the two sides (11) and the core material (13), and a second expandable portion (122) arranged between the other of the two sides (11) and the core material (13).
[0009] [3] The pelvic support according to either [1] or [2], characterized in that the insertion hole (11a) is drilled in such a way that it is roughly in the shape of a V or roughly inverted V on one side of the two sides (11) and the other side.
[0010] [4] The pelvic supporter according to either [1] or [2] above, further comprising a connecting portion (4) for connecting the abdominal belt portion (2), wherein the connecting portion (4) and the pelvic support portion (1) are fixed together approximately in the center of the connecting portion (4).
[0011] [5] The pelvic supporter according to [3], further comprising a connecting portion (4) that connects the abdominal belt portion (2), wherein the connecting portion (4) and the pelvic support portion (1) are fixed together approximately in the center of the connecting portion (4). [Effects of the Invention]
[0012] According to the pelvic support according to the present invention, when the user wears it, a contracting force acts on the elastic part, pulling the adjustment belt positioned around the user's pelvis toward the back. This brings the ilium, which forms the pelvis, closer to the sacrum, fixing the sacroiliac joint between the ilium and the sacrum, thereby alleviating symptoms and providing conservative treatment for users suffering from sacroiliac joint dysfunction.

Figure 6 is a front view showing the pelvic support according to the second embodiment of the present invention.
[0016] [First Embodiment] As shown in Figures 1 to 4, the pelvic support of this embodiment includes a pelvic support part 1, an abdominal band part 2, an adjustment belt 3, a connecting part 4, and so on. As shown in Figure 5, the pelvis P is formed from the sacrum S, which is located in the center of the buttocks and has a roughly inverted triangular shape, and the ilium I, which is located on either side of the sacrum S and has an ear-like shape, and the joint between them is called the sacroiliac joint SJ.
[0017] The pelvic support portion 1 is a member that supports the posterior side of the user's pelvis P as shown in Figure 5. In this embodiment, the pelvic support portion 1 includes both sides 11, 11 made of a rigid material with an insertion hole 11a through which the adjustment belt 3 is inserted, and an expandable portion 12 disposed between the both sides 11, 11, which is softer than the both sides 11, 11 and expands and contracts in the direction of the user's waist. Furthermore, in this embodiment, a core material 13 made of a rigid material is provided between the both sides 11, 11, which is elongated in the vertical direction along the longitudinal direction of the user's sacrum.
[0018] As shown in Figure 1, the side portions 11,11 are members located on both sides of the pelvic support portion 1 in the left-right direction when the user wears the present invention. The side portions 11,11 are made of a harder material than the expandable portion 12 and are not expandable or expandable with difficulty. Each side portion 11,11 has an insertion hole 11a through which the adjustment belt 3 is inserted. The insertion hole 11a allows the expandable portion 12 to be stretched so that when the user fastens the pair of abdominal belt portions 2 together, the adjustment belt 3 pulls on it, and a contracting force acts on the expandable portion 12. In this embodiment, the insertion holes 11a are drilled on one side portion 11,11 and the other side in a roughly V-shape or roughly inverted V-shape. This allows the contracting force of the expandable portion 12 to act evenly in the left-right direction when the user wears it. In this embodiment, a total of four through holes 11a are drilled: two upper and two lower on one side of the two side portions 11·11, and two upper and two lower on the other side. The two through holes 11a located on the upper side of one side portion 11·11 and the other side are drilled in an inverted V shape, while the two through holes 11a located on the lower side of one side portion 11·11 and the other side are drilled in a V shape.
[0019] The telescopic part 12 is a member disposed between the both side parts 11·11, softer than the both side parts 11·11, and capable of telescoping in the left - right direction of the user, more specifically, in the direction around the user's waist. In this embodiment, since the core material 13 is disposed substantially at the center of the pelvic support part 11, it is formed from a first telescopic part 121 disposed between one of the both side parts 11·11 and the core material 13 and a second telescopic part 122 disposed between the other of the both side parts 11·11 and the core material 13. When the user attaches the pelvic supporter of the present invention around the pelvis, the telescopic part 12 is pulled and extended, and when worn, a force that causes the telescopic part 12 to contract acts, so that the adjustment belt 3 disposed around the user's pelvis is pulled to the back side through the both side parts 11·11. As a result, the ilium I forming the pelvis P is brought closer to the sacrum S, and the sacro - iliac joint SJ between the ilium I and the sacrum S is fixed, enabling alleviation of symptoms and conservative treatment for users suffering from sacro - iliac joint disorders. Since the telescopic part 12 is capable of telescoping, it is preferably formed of a member having rubber elasticity such as fibers knitted with rubber threads or rubber.
[0020] As described above, the core material 13 is a member that is long in the vertical direction along the longitudinal direction of the user's sacrum S between the both side parts 11·11, is disposed substantially at the center of the pelvic support part 1, and is harder than the telescopic part 12. The core material 13 supports the user's sacrum S and also serves as a guide for the position when wearing the pelvic supporter of the present invention. The core material 13 is preferably formed in a long plate shape or a rod shape from a resin such as polyolefin or polyester.
[0021] The abdominal belt parts 2 are a pair of members that cover the user's abdomen and are detachable from each other. Each abdominal belt part 2·2 is fixed to one end side of each adjustment belt 3. When the user wears the pelvic supporter of the present invention, the user can pull each abdominal belt part 2·2 left and right to adjust the tightening degree of the adjustment belt 3 and attach each abdominal belt part 2·2 so as to cover the user's abdomen.
[0022] In this embodiment, as shown in Figure 3, the abdominal band portions 2-2 have a roughly rectangular shape that is long in the left-right direction with rounded ends. A hook-shaped hook fastener 21 having a predetermined length in the left-right direction of the user is provided on the front side of at least one of the abdominal band portions 2-2, and a loop-shaped hook fastener 22 having a predetermined length in the left-right direction of the user is provided on the back side of the abdominal band portions 2-2, as shown in Figures 1 and 2. These hook-shaped hook fasteners 21 and loop-shaped hook fasteners 22 allow the pair of abdominal band portions 2-2 to be attached to and detached from each other when the user puts on the pelvic support of the present invention. In this embodiment, the hook-shaped hook fastener 21 is provided on the front side of one of the abdominal band portions 2-2 and the loop-shaped hook fastener 22 is provided on the back side of the abdominal band portion 2-2, but in other embodiments, the hook-shaped hook fastener 21 can be provided on the back side of the abdominal band portion 2-2 and the loop-shaped hook fastener 22 can be provided on the front side of the abdominal band portion 2-2. Furthermore, in this embodiment, a hook-shaped hook-and-loop fastener 21 and a loop-shaped hook-and-loop fastener 22 are provided on the abdominal band portion 2 to make the pair of abdominal band portions 2 detachable from each other. However, in other embodiments, buttons, hooks, magnets, etc., can be provided on each of the pair of abdominal band portions 2, as long as they are detachable from each other.
[0023] The adjustment belt 3 is a pair of members that are inserted through insertion holes 11a drilled on each side of the pelvic support portion 1, fixed to the abdominal band portion 2 at one end, and equipped with a locking portion 31 at the other end. The adjustment belt 3·3 is made of a material that is not stretchable or difficult to stretch, so as not to stretch at least more than the stretchable portion 12 in the direction of the user's waist. These adjustment belt 3· 3 operates as follows when the user puts on the pelvic support of the present invention. That is, first, the locking parts 31-31 of the adjustment belts 3-3 are locked together, the pelvic support part 1 is positioned in approximately the desired location, and then, when the pair of abdominal band parts 2-2 are attached to each other, the length of the adjustment belts 3-3 is adjusted by extending the elastic part 12 so that it moves through the insertion hole 11a and tightens around the user's pelvis P. As a result, when the user puts it on, a contracting force acts on the elastic part 12, pulling the adjustment belts 3-3, which are positioned around the user's pelvis P, toward the back. This brings the ilium I that forms the pelvis P closer to the sacrum S, fixing the sacroiliac joint SJ between the ilium I and the sacrum S, thereby alleviating symptoms and providing conservative treatment for users with sacroiliac joint dysfunction.
[0024] In this embodiment, each adjustment belt 3-3 is provided in pairs, one above the other. One end of each belt is fixed to the abdominal band portion 2-2, and the other end is joined together by a locking portion 31-31 located at the tip. By providing two adjustment belts 3-3 each above and below, the sacroiliac joint SJ, which extends vertically in the user's body, can be fixed with approximately equal force. In other embodiments, each adjustment belt 3 can be provided as a single belt or as a set of three or more belts, as long as the sacroiliac joint SJ can be fixed with approximately equal force.
[0025] In this embodiment, the locking portions 31, 31 provided on the other end of each adjustment belt 3, 3 are hook-and-loop fasteners. As shown in Figure 2, a hook-shaped member is provided on the front side of the adjustment belt 3, 3, and as shown in Figure 1, a loop-shaped member is provided on the back side of the adjustment belt 3, 3. These locking portions 31, 31 of the hook-shaped member and loop-shaped member allow the user to first lock the locking portions 31, 31 together when putting on the pelvic support of the present invention, thereby positioning the pelvic support portion 1 in approximately the desired location. In this embodiment, the hook-shaped member is provided on the front side of the adjustment belt 3, 3, and the loop-shaped member is provided on the back side of the adjustment belt 3, 3. However, in other embodiments, the hook-shaped member may be provided on the back side of the adjustment belt 3, 3, and the loop-shaped member on the front side of the adjustment belt 3, 3. Furthermore, in this embodiment, hook-shaped members and loop-shaped members are provided as locking parts 31-31 to enable the pair of adjustment belts 3-3 to lock together. However, in other embodiments, buttons, hooks, magnets, etc., can be provided on each of the pair of adjustment belts 3-3, as long as they can lock together.
[0026] The connecting portion 4 is a member that connects a pair of abdominal band portions 2, 2, and the connecting portion 4 and the pelvic support portion 1 are fixed to each other approximately in the center of the connecting portion 4. The connecting portion 4 keeps the adjustment belts 3, 3 protruding from the insertion hole 11a to a predetermined length, and when not in use, the length of the adjustment belts 3, 3 relative to the pelvic support portion 1 does not change, allowing for neat storage. The connecting portion 4 is preferably larger than the vertical length of the pelvic support portion 1 and formed in a band shape along the left-right direction, which is the longitudinal direction of the adjustment belts 3, 3, so that the silhouette of the pelvic support of the present invention looks smart when worn. Furthermore, the connecting portion 4 is preferably made of a material that stretches more in the left-right direction than the expandable portion 12 of the pelvic support portion 1 in order to make it easier to fasten the abdominal band portions 2, 2 together, and is preferably made of a mesh-like fabric in order to improve breathability.
[0027] In this embodiment, as shown in Figure 3, an anti-slip portion 41 is provided on the front side of the connecting portion 4 at approximately the center of the connecting portion 4. Three rectangular anti-slip portions 41 are formed approximately parallel to each other and extending vertically at approximately the center of the connecting portion 4. The anti-slip portions 41 prevent friction between the pelvic support of the present invention and clothing such as trousers, skirts, or shirts worn over the pelvic support, thus preventing wear on the clothing and the connecting portion 4. It is preferable that the outer surface of the anti-slip portion 41 that comes into contact with clothing is made of a material with high frictional resistance, such as rubber. In this embodiment, three rectangular anti-slip portions 41 are formed approximately in the center of the connecting portion 4, but multiple portions can also be arranged regularly or irregularly in a polygonal or approximately circular shape across the entire connecting portion 4, as long as wear on the clothing and the connecting portion 4 can be prevented.
[0028] [Second Embodiment] As shown in Figure 6, the pelvic support of this embodiment includes a pelvic support section 1, an abdominal band section 2, an adjustment belt 3, and the like. This embodiment differs from the first embodiment in that it does not have a core material 13, a connecting section 4, or an anti-slip section 41 associated with the connecting section 4. The pelvic support section 1, the abdominal band section 2, and the adjustment belt 3 are substantially the same as those described in the first embodiment for each component and associated components.
[0029] In this embodiment of the pelvic support, as in the first embodiment, when the user puts on the pelvic support of the present invention, it operates as follows. That is, first, the locking parts 31,31 of the adjustment belts 3,3 are locked together, the pelvic support part 1 is positioned in approximately the desired location, and then, when the pair of abdominal band parts 2,2 are attached to each other, the length of the adjustment belts 3,3 is adjusted by extending the elastic part 12 so that it moves through the insertion hole 11a and tightens around the user's pelvis P. As a result, when the user puts it on, a contracting force acts on the elastic part 12, pulling the adjustment belts 3,3 positioned around the user's pelvis P towards the back via both sides 11,11. This brings the ilium I that forms the pelvis P closer to the sacrum S, fixing the sacroiliac joint SJ between the ilium I and the sacrum S, thereby alleviating symptoms and providing conservative treatment for users with sacroiliac joint dysfunction.
[0030] Embodiments of the pelvic support of the present invention have been described above with reference to the drawings (Figures 1 to 6). However, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence. [Explanation of Symbols]
