Description

  The present invention relates to a iliac crest belt that can be widely used for lower back pain or prevention of back pain or pelvic correction without reducing the burden on the lower back and without impairing the motor function of the hip joint and greater trochanter.

  Today, there are many people who are worried about the waist. Many have pain in the lower back, limiting their daily activities. Low back pain ranges from acute low back pain that occurs suddenly like a tight waist to chronic low back pain that occurs repeatedly. There are various causes, frequency of occurrence, and degree of pain.

  Even in sports or physical labor that overuses muscles, or in desk work that keeps sitting for a long time without overworking muscles, low blood circulation, muscle stiffness, lymphatic retention, etc. may induce low back pain. Most of the causes of these low back pains are pains caused by acute or chronic stimulation of surrounding nerves due to defects derived from the sacrum or lumbar vertebrae in the pelvis and related muscles surrounding them.

  The pelvis is located at the center of the whole body, is the base of the whole body, and plays a cushioning role. It is thought that muscles support the pelvis, and muscle weakness, fatigue, aging, or stress causes pelvic distortion and causes pain. In this case, it is caused by structural distortion and deformation of the pelvic skeleton, and this is not easy to solve.

  In many cases, methods such as physical therapy and massage therapy are used to treat low back pain. Various waist belts and corsets are manufactured and sold as these combination therapies. They have a structure that fixes the hips and lumbar region of the entire lumbar region and restricts its functions, and maintains a stable posture that does not overwhelm the lumbar and pelvis due to the strong compression force in the waistline direction, It reduces the burden on the spine, etc., and relieves pain and anxiety. In addition, when the symptom is severe, the affected part may be forcibly fixed using a cast or the like. These all relieve pain by restricting the motion that causes pain.

  For example, as disclosed in Patent Document 1, these waist belts and corsets can be attached by providing surface fasteners at both end portions of a belt-like belt made of a single elastic material, and a predetermined elastic member can be attached. A part provided with a pad or the like and having a holding property of the waist, and as disclosed in Patent Document 2 in order to enhance the tightening force and holding force, a waist fixing band and a pelvis for holding the waist A medical corset has been proposed in which a pelvic fixation band to be held is integrally connected at the waist.

  Further, Patent Documents 3 and 4 provide a main belt as a supporter and a secondary belt that enhances the holding power of the main belt as a waist belt that enhances the holding effect of the waist and is easy to wear. There is disclosed a device that is adapted to be mounted.

  Further, in Patent Document 5, as a corset having a structure that enhances the holding effect of the waist, an upper belt portion wound around the waist portion and an intermediate belt portion below the upper belt portion are integrally connected to each other, and a pair of thighs are provided. A corset has also been proposed in which a pair of lower belts surrounding the portion are provided continuously from the middle belt portion.

  Further, Patent Document 6 discloses a belt-like waist belt that is wound from the waist to the abdomen as a waist supporter to be worn on the waist for the purpose of reducing the burden on the waist for the purpose of reducing back pain or preventing back pain, and this waist belt. A lumbar support member provided at an inner central portion of the lumbar region and abutted against the lumbar vertebrae, and provided at both inner sides of the lumbar belt and abutted against a pair of left and right iliac portions on the side surface of the lumbar region A lumbar supporter has been proposed that includes a pair of side support members and an auxiliary belt that is provided at the center lower part of the waist belt and covers the hip joint from above the buttock and is wound with both ends connected to each other at the lower abdomen. .

  Patent Document 7 discloses a band-shaped main body that circulates around the lumbar region and a Tanda pad mounted at a position corresponding to the Tanda portion, and a lumbar sacral healing pad mounted at a position corresponding to the lumbar portion or a position corresponding to the sacral portion. In addition, the lumbar sacral healing pad and Tanda are equipped with a pressure adjustment rubber that applies an external force to press the Tanda part against the Tanda pad and also applies an external force to press the lumbar sacral healing part or the sacral part against the lumbar sacral healing pad. A support belt has been proposed in which the lumbar sacral healing pad can be used for either lumbar pressing or sacral pressing by changing the relative height of the pad.

  These waist belts, support belts, and corsets alleviate pain by fixing the hips and waist of the entire waist, and restricting the movement that causes pain. However, many of them have structures that hinder the function of the hip joint.

  As described above, conventional supporters, waist belts, and corsets fix the posture and relieve pain in the waist by tightening the entire circumference of the waist from the abdomen to the waist with a strong compression force. At this time, in order to obtain a more effective effect, it is necessary to tighten with a stronger force, and the supporter, the waist belt, and the corset need to be wider and sometimes the auxiliary belt is attached. In addition, the waist and hip joints are positioned one above the other, so a generally wide belt is required to secure them simultaneously. This wide belt squeezes and restrains the abdomen over a wide area, so it is harsh and uncomfortable, and may cause difficulty breathing and loss of appetite. In many cases, even the functions of the hip joint are restricted, so that even basic daily life operations necessary for daily life are not easy, and the wearer feels more discomfort and stress.

  In view of the above-mentioned background art, the present invention reduces the abdomen tightening force from the characteristic shape of the waist belt, stably fixes both the waist and hip joints, ensures the function of the natural joint as much as possible, and is comfortable. It is providing the iliac crest belt which has a feeling of wear.

  As a means for achieving the above object, according to the present invention, in the first means, a belt-shaped elastic iliac crest belt for preventing back pain or correcting pelvis is wound around the body from the waist to the abdomen. It consists of a belt center portion having longitudinal stretchability that abuts the wearer's back surface, belt end portions on both sides, and a longitudinal belt-like belt side portion that connects the belt ends in the longitudinal direction. It is an iliac crest belt that has a shape with a raised belt center compared to the belt ends on both sides, and is attached to the belt ends on both sides with hook and loop fasteners attached to both belt ends. .

  Since this iliac crest belt has elasticity and has detachable hook and loop fasteners at both left and right ends, the fastening strength can be appropriately adjusted and the belt can be wound around and fixed around the waist. In this case, in order to more firmly fix and support the waist, a vertical bone can be attached to the center. Furthermore, when the iliac crest belt is worn, the inner surface of the central part of the belt is in contact with the upper part of the hip from the lower lumbar part of the back of the body to protect and subsidize the whole pelvis in the iliac region. . Because of the characteristic shape of this iliac crest belt, as described above, the inner surface of the belt center part abuts against the upper part of the hips from the lower lumbar part of the back of the body. The position where the belt side of the iliac crest belt contacts at the same time without disturbing the silhouette due to the iliac crest belt, and further preventing the movement of the lower limbs without impeding the motor function of the greater trochanter of the pelvis It is possible to avoid delays in functional recovery and depression. Thus, the iliac crest belt has a shape and a structure that fits the waist in a three-dimensional manner that can effectively tighten the pelvis while ensuring the movement of the hip joint.

  The second means is a stretchable iliac crest belt for preventing back pain or correcting the pelvis that is wound around the body from the waist to the abdomen, the belt end portions on both sides and the belt belt side portions in the left and right diagonal directions; The center part of the belt consisting of left and right members is joined in the longitudinal direction, and the member at the center part of the belt consisting of left and right members is shaped like a double mountain. It is the iliac crest belt of the 1st means which consists of a reverse reverse omega shape.

  The central part of the iliac crest belt has an inverted omega-shaped double-mountain shape, and this abutment position on the flank of the body has the function of the greater trochanter of the protrusion on the upper end of the femur. The position where the belt end portions on both sides abut without being obstructed is Tanda, which is an iliac crest belt designed to reduce pressure on the lower abdomen.

  In the third means, the belt-shaped belt side portions in the left and right oblique directions connecting the belt center portion of the iliac crest belt and the belt end portions on both sides of the iliac crest belt in the longitudinal direction have an oblique angle at the center of the belt. The movement function of the lower leg of the body is maintained without a sense of incongruity by the slanted belt-shaped belt side portion that is at an angle of 20 ° to 40 ° with respect to the member of the lower part, and compression of the lower abdomen , The pelvis in the iliac region is surrounded and protected and assisted, and the ratio of the width and length of each member of the belt center member and the belt side member in the oblique direction, that is, the aspect ratio is 1 The length of the iliac crest belt of the second means is 1.5 to 3.5.

  The shape of this iliac crest belt is important to ensure the motor function of the lower limbs, and is formed by the belt side member, which is the part that joins the belt center member and the members on both ends attached with the hook-and-loop fastener The angle to perform is 20 ° to 40 °, preferably 25 ° to 35 °. In this case, in order to support the waist more strongly, a vertical bone that is the direction of the back of the body can be attached to the center of the belt. And the inside of the back part of the belt center part of the iliac crest belt can maintain the motor function of the thigh lower limbs without a sense of incongruity, and firmly protect and assist the entire pelvis to surround the pelvis, It is designed to have a shape that does not give a sense of incongruity to the silhouette of the buttocks when worn.

  In the fourth means, the iliac crest belt has a support member made of a stretchable material constituting the belt, and the stretchable material is made of a soft resin, hard rubber, foamed resin, or a three-dimensional fabric. The iliac crest belt has a thickness, bending hardness and elasticity so as not to be crushed by the tightening force of the iliac crest belt, and an anti-slip in the vertical direction is formed on the inner side of the support member. The stretchable material at 150mm has a stretch ratio of 40% or less, which is the ratio of the stretched length to the original material length, and the stretch ratio on the abdomen side and the back side is 5-25% and other parts It is a iliac crest belt of the 3rd means which is a thing relatively lower than 20 to 40% of the elongation rate of.

  This iliac crest belt is stretchable in the longitudinal direction, and its inner surface is made of a surface having a non-slip in the width direction, so when it is worn around the waist of the underwear worn on the body, The inner surface of the belt engages with the surface of the undergarment and does not easily slip off.

  In the fifth means, the elastic support material constituting the iliac crest belt is excellent in sweating property so that the inner surface of the support material of the iliac crest belt that comes into contact with the underwear on the skin side permeates sweat when worn on the body. The iliac crest belt of the fourth means is made of a material having a high coefficient of friction against underwear.

  In the sixth means, the position of the iliac crest belt is described on the surface of the iliac crest belt as a guide diagram on the iliac crest belt. On the female end of the hook-and-loop fastener attached to the belt end of the belt, the male surface is moved back and forth in the belt length direction and adjusted according to the length of the waist. The iliac crest belt of the fifth means.

  This iliac crest belt is created by joining six members together. However, the two members at the central portion of the iliac crest belt composed of these six members can be configured as five members as one member. The fabric constituting 6 or 5 members of the iliac crest belt is stretchable in the longitudinal direction, but is made of a non-stretchable fabric in the width direction, and the waist portion where each member abuts. Depending on the position, the longitudinal direction of each member constituting the iliac crest belt is different. Therefore, when the iliac crest belt is deployed sideways, the left and right parts of the center part of the belt are slightly higher than the left and right ends, but it is raised upwards in a double mountain shape and has an inverted omega shape, When this iliac crest belt is attached to the body, each member constituting the iliac crest belt can support each part of the body around the waist with an optimum tension.

  In the seventh means, the iliac crest belt is a iliac crest belt of the sixth means in which the supporting member is formed from a three-dimensionally structured fabric, and the three-dimensionally structured fabric itself is formed by combining materials having different stretchability. is there.

  This iliac crest belt is formed from a three-dimensional fabric and has elasticity, so it has a non-slip effect and does not induce side effects such as rash even when worn directly on the skin, and also has good sweating and breathability It is.

  In order to fix both ends of these iliac crest belts and wind them around the waist, a reinforcing belt can be provided on the front side or the back side of the iliac crest belt. In addition, small holes having a diameter of 5 to 10 mm can be provided in a distributed manner on the entire belt side portion of the iliac crest belt at intervals of approximately 3 cm. When the iliac crest belt having small holes dispersed in the entire side surface of the belt is directly attached to the skin of the body, effects of promoting blood flow in the body surface layer and improving lymph can be expected. The size and number of small holes provided on the entire belt side portion of the iliac crest belt are not particularly defined.

  The iliac crest belt of this invention is not in a shape in which the belt center part in contact with the wearer's back side and the left and right end parts in contact with the abdomen side are connected in a straight line, but in comparison with the left and right ends, the belt center part The two parts that form the belt or the one part that forms the center of the belt are slightly raised upwards in a double mountain shape, like the omega shape in the reverse direction of the lowercase omega in Greek letters. When the iliac crest belt is worn around the waist, the inner surface of the center of the belt abuts against the upper part of the lumbar spine from the lower back of the body. Without disturbing the silhouette due to wearing the belt, at the same time, the position where the belt side part of this iliac crest belt abuts without disturbing the motor function of the greater trochanter of the pelvis from the shape of the iliac crest belt And even the lower limb luck It is possible to avoid the delay and feelings of depression of functional recovery. That is, the iliac crest belt of the present invention designed to circulate obliquely along the iliac crest of the pelvis of the flank rather than the belt that horizontally circulates the waist and abdomen as disclosed in the prior art Can stably fix both the lumbar part and the pelvis part while being narrow. In addition, since the iliac crest belt is stretchable in the longitudinal direction, the tightening force can be adjusted freely, and the iliac crest belt designed so that the tightening position of the front abdomen is located slightly in the lower abdomen With this shape, the feeling of pressure is reduced without directly pressing the abdomen. In this manner, the iliac crest belt has a shape and a structure that effectively tightens the pelvis while ensuring the movement of the hip joint and three-dimensionally fitting the waist.

It is the front view which looked at the iliac crest belt of the other Example of this invention from the inner surface side.

The support member constituting the iliac crest belt 1 of the present invention needs to be hard enough not to be crushed by the tightening force of a commonly used waist belt. However, if it is too hard, problems such as hitting the body will occur. Therefore, the material is a soft resin, a hard rubber, a foamed resin, a fabric having a three-dimensional structure such as a double raschel fabric using a monofilament thread, a fabric having a honeycomb structure, and the like. A member having an appropriate bending hardness, thickness and elasticity that does not buckle and is not crushed is suitable. For example, a low resilience soft foam made of a crosslinked foam of a styrene elastomer, a foamed resin made of ethylene vinyl alcohol (hereinafter referred to as “EVA”), etc. are made to a predetermined thickness. These materials, 25% compressive hardness test value by JIS K6767 is, in the styrene-based elastomer include the 2.6 N / cm ^2, the EVA 4.02N / cm ^2, these belts iliac crest Belt 1 It is suitable as the support member 3a of the side part 3 and the support member 2a of the belt center part 2 which is a waist part. In this way, by using a thin and flexible material having a relatively high stretchability, it is possible to enhance the fit to the body and reduce the feeling of tightening.

  Hook fasteners 4 are attached to both ends of the iliac crest belt 1. The surface fastener 4 is attached by attaching the male surface 4a and the female surface 23b of the surface fastener 4 to the appropriate corresponding positions of the belt end portions 6 on both sides of the front surface 1a and the back surface 1b of the iliac crest belt 1, respectively. Is formed. The male surface 4a and the female surface 23b are provided with a large number of air holes 4c in order to improve air permeability.

  The support member 3a constituting the belt side portion 3 of the iliac crest belt 1 or the support member 2a of the waist portion, that is, the belt center portion 2 is made of a stretchable member as described above. As an example of the member, a soft resin, a hard rubber, a foamed resin, or a fabric having a three-dimensional structure can be given. These are materials having a bending hardness, a thickness and an elasticity so that the shape is not crushed by the tightening force of the iliac crest belt 1, and having a shock absorbing property. The belt width is 50 mm to 150 mm, preferably 80 mm to 120 mm. The stretch member has a stretch rate of 40% or less, and the part contacting the abdomen and back of the body is processed with a relatively low stretch rate. High material is used. Usually, the former is appropriately designed in the range of 5% to less than 20% expansion and contraction, and the latter is 20% to less than 40%.

  As shown in FIG. 2, the iliac crest belt 1 is manufactured by connecting six members with a belt seam allowance 5. The belt end portions 6 on both sides of the iliac crest belt 1 composed of these six members are fitted with surface fasteners 4 and are wound around the waist of the body by the surface fasteners 4 on the belt end portions 6 on both sides. To do. The double mountain-shaped member that is the belt central portion 2 of the iliac crest belt 1 is composed of one member or two members. The shape of these iliac crest belts 1 is important for ensuring the motor function of the lower limbs of the body. The angle between the belt side part 3 between the belt end part 6 on both sides of the iliac crest belt 1 for joining the member of the belt center part 2 of the iliac crest belt 1 and the hook and loop fastener 4 is The angle is 20 ° to 40 ° with respect to the horizontal, preferably 25 ° to 35 °. In order to support the waist of the body more strongly, the seam allowance 5 of the joint with the belt side part 3 on both sides of the belt center part 2 is set as a bone seam allowance 5a as shown in FIG. It is also possible to insert a hard vertical bone 7 inside.

  Furthermore, the wearer of this iliac crest belt 1 can be used by using a material having high shock absorption as the support member 3a of the belt side 3 of the iliac crest belt 1 or the support member 2a of the belt center 2 which is the waist. It can also prevent fractures and injuries such as the iliac and tailbone when the falls. As a material having a high impact absorption capacity, the above-mentioned low-rebound soft foam of styrene elastomer or EVA foam resin is suitable. The impact absorbability expected as a material for the support member 3a of the belt side portion 3 of the iliac crest belt 1 and the support member 2a of the belt center portion 2 is desirably 50% or more in terms of impact absorption rate.

  Furthermore, the anti-slip processing of the iliac crest belt 1 can be prevented by applying an anti-slip process to the inner surface of the iliac crest belt 1, preferably to the buttocks. As an example of the anti-slip processing, a resin having an anti-slip effect is printed on the inner surface of the iliac crest belt 1 or is sewn. Any method is possible if possible. The anti-slip processing may be performed on the surface facing the body side inside the support member 3a of the belt side portion 3 of the iliac crest belt 1 and the support member 2a of the belt center portion 2.

  The support member 2a of the belt central portion 2 of the iliac crest belt 1 that contacts the portion of the lumbar vertebra 11 on the back side of the body is formed in the shape of an inverted omega character when worn on the body, and is a member applied to the portion of the lumbar vertebra 11 Is more strongly pressed against the portion of the lumbar vertebra 11, and the stability of the portion of the lumbar vertebra 11 is further increased, and the effect of preventing back pain can be enhanced. Further, the support member 3a of the belt side portion 3 of the iliac crest belt 1 is at an angle of 20 to 40 °, preferably an angle of 25 to 35 ° with respect to the horizontal of the belt center portion 2 of the inverted omega character shape. Thus, the iliac crest belt 1 is integrally joined. By maintaining this angle, the motion function of the hip joint 15 and the greater trochanter 16 is not hindered, and the pelvis 12 can be stably held. This further increases the sense of stability of the entire waist. Further, it is possible to prevent the iliac crest belt 1 from sliding up due to the wearer's body shape and usage conditions.

  Further, in order to reduce heat and stuffiness when worn, the support member 3a of the belt side portion 3 and the support member 2a of the belt center portion 2 disposed in the left and right iliac portions 14 and the lumbar spine 11 portions are ventilated. In order to improve the property, a vent hole may be provided. In addition, if a fabric having a three-dimensional structure such as a double raschel fabric or a fabric having a honeycomb structure is used, higher breathability can be provided.

  As shown in FIG. 6, a large number of small holes 3b having a diameter of 5 to 10 mm dispersed in a staggered manner at intervals of about 3 cm can be provided on the entire surface of the left and right belt side portions 3 of the iliac crest belt 1. When the iliac crest belt 1 provided with a large number of small holes 3b dispersed in a staggered manner on the entire surface of the belt side part 3 is directly attached to the skin of the body, Enter with the surface layer of the loose. Since the portion of the surface layer of the body that has entered is not directly compressed by the belt side portion 3 and is in a released state, blood flow is promoted by the surface layer portion of the body, and lymph is further improved. Excellent effects are expected.

  Next, an embodiment of a preferred mounting mode of the iliac crest belt 1 of the present invention will be described with reference to FIG. The iliac crest belt 1 of this embodiment is wound so as to cover the upper part of the buttocks from the portion of the lower spine 18 of the body, and the left and right sides of the iliac crest belt 1 by the surface fastener 4 on the front surface of the lower abdomen 19. The belt end 6 is connected. Therefore, if the structure is entirely wrapped around the femur 17, it is possible to increase the stability and prevent the proper attachment position of the body and the iliac crest belt 1 from being displaced. The support effect of the waist by 1 can be enhanced.

  The mounting mode of the iliac crest belt 1 of the present invention is not limited to the above embodiment, and the iliac crest belt 1 itself is not limited to the belt material or shape. The material and shape of the support member 3a of the belt side portion 3 of the iliac crest belt 1 and the material and shape of the support member 2a of the belt central portion 2 that is the waist may be members having desired bending hardness, thickness, and elasticity. Can be used as appropriate.

  Hereinafter, the wearing result which is the usage example of the iliac crest belt 1 of this invention is demonstrated. The tightness applied to the lower abdomen 19 when the iliac crest belt 1 of the present invention is worn causes the feeling of pressure applied to the underwear worn on the lower abdomen 19 to be substantially equivalent to the conventional waist belt. However, with respect to the hip joint 15, the motor function is not suppressed, and the iliac crest belt 1 of the present invention has a very good motor function of the hip joint 15 as compared with the conventional waist belt. This is because the iliac crest belt 1 of the present invention is expanded and contracted in each longitudinal direction composed of a belt center part 2, a belt side part 3, and a belt end part 6, and the belt side part 3 and the belt end part. As shown in FIG. 2, the shape of the member of the portion 6 in the longitudinal direction is not a straight line, but the belt side portion 3 is a double omega shape having a reverse omega shape opposite to the Greek lowercase letter omega. The belt end 6 in the horizontal direction has a shape that spreads obliquely downward like a mountain-shaped outer skirt.

  In addition, as a material of the support member 3a of the belt side portion 3 and the support member 2a of the belt center portion 2 of the iliac crest belt 1 of the present invention, for example, a trade name “Pitafoam” which is a foam of styrene elastomer, The trade name “Transform”, which is a foam of ethylene vinyl alcohol, can be used. Further, a three-dimensionally structured fabric such as a double raschel fabric or a honeycomb structured fabric can also be used as a material for the support member 3a of the belt side portion 3 and the support member 2a of the belt center portion 2.
