Description

  The present invention relates to a sacral support device, and more particularly to a sacral support device that keeps the pelvis forward tilted when sitting.

  Conventionally, it is known from Non-Patent Document 1 that lumbar flexion movements and lumbar kyphosis postures (the state where the spine protrudes backward and bends) cause lumbar damage and cause back pain and lower limb pain. It has been.

  Inducing a lumbar lordosis posture in a sitting position is important for prevention and improvement of lumbar vertebral disorder, but a lumbar kyphosis tendency tends to be stronger when sitting on a flat floor or sitting on a flat chair. (Non-patent Document 1).

An example of a lumbar support for obtaining a lumbar lordosis in a sitting position is disclosed in Non-Patent Document 1.
However, since this lumbar vertebra support device is structured to support the entire lumbar vertebra, it is about the same size as a pillow, difficult to carry, and difficult to wear on the go.

  Accordingly, the present invention has been invented to solve the above-described problems, and an object thereof is to provide an easily portable sacral support for obtaining a lumbar lordosis in a sitting position.

  In order to achieve the above object, a sacral support device according to the present invention comprises a plate-like member having a contact surface that supports a sacrum, and the contact surface faces from the upper edge to the lower edge of the sacrum support device. An inclined surface that gradually reduces the thickness of the plate-like member is formed rearward.

  The sacral support device of the present invention includes a contact surface that supports the sacrum, and since the contact surface is inclined backward, the user can sit the sacrum support device of the present invention behind the sacrum when sitting, for example, a chair. Sacral anteversion can be obtained by inserting it between the back plate and the lumbar spine can be prevented and improved.

  Moreover, since the sacral support tool of the present invention is configured to obtain the forward tilt of the sacrum by supporting the sacrum rather than the lumbar vertebra, it can be made smaller than an instrument configured to support the lumbar vertebra. This can be accomplished by tilting the sacrum, which is the foundation of the lumbar spine, so that the lumbar spine assumes a prone posture, without supporting the lumbar spine itself. In particular, it is based on the finding that the sacrum is smaller than the lumbar spine.

  The sacral support of the present invention preferably has belt means for allowing the user to detachably mount the sacral support.

  With the belt means, when the user sits on the seat surface of the chair while wearing the sacral support device and presses the sacral support device against the back plate of the chair, the pelvis is tilted forward by the inclined surface and the lumbar spine Is maintained in a prone posture, thereby preventing and improving lumbar injury. When the belt means is provided, the sacral support can be hidden in the clothes, and the sacral support can be used without being known to others, and the sacral support is prevented from falling off during use. It is possible to eliminate the need to always press against the back plate of the chair.

In this invention, it is preferable to have a longitudinal groove for receiving the sacral spinous process of the user, which is formed on the contact surface of the sacral support and extends in the center in the width direction.
By forming the sulcus, the sacral spinous process can be received, thereby reducing user discomfort and stabilizing the sacral support in the midline trunk.

Further, it is preferable that both upper side portions of the contact surface of the sacral support tool are cut to form a posterior superior iliac spine support surface for supporting the posterior superior iliac spine of the user.
By supporting the posterior superior iliac spine with the posterior superior iliac spine support surface, excessive movement of the sacroiliac joint can be suppressed.

Furthermore, it is preferable to have a cushioning material attached to the contact surface of the sacral support.
The pressure applied to the sacrum can be dispersed by the cushioning material.

Furthermore, the chair which has a backplate provided with the sacral support tool of the said structure can be provided.
Since the sacral support is provided on the back plate of the chair, it is possible to eliminate the need to always press the sacrum support against the back plate of the chair so that the sacrum support does not fall off during use.

Moreover, the standing structure which has a support plate provided with the sacral support tool of the said structure can be provided.
Since the sacral support is provided on the support plate, it is possible to eliminate the need to press the sacrum support against the back plate of the chair so that the sacrum support does not fall off during use.

  Hereinafter, embodiments of the sacral support according to the present invention will be described with reference to the accompanying drawings.

1 to 4, the sacral support according to the present invention is indicated generally by the reference numeral 2.
As can be clearly seen in FIG. 1, the sacral support tool 2 is generally composed of an inverted triangular plate. The sacral support tool 2 can be made of various materials such as resin such as foamed polyurethane and foamed polyethylene, wood, metal, stone, cork, earthenware, rubber, and the size is 5-20cm in height and 5-20cm in width. Is preferred.

  The sacral support tool 2 is provided with a contact surface 2A that supports the sacrum of the user when in use, that is, the contact surface 2A that supports the sacrum. When viewed, an inclined surface is formed as a whole, and the thickness of the plate 2 is gradually reduced backward from the upper edge toward the lower edge by the inclined surface 2A. The inclined surface 2A is a flat surface, but may be a convex curved surface.

  2 and 3, the abutment surface 2A of the sacral support tool 2 has a longitudinal groove 3 for receiving a user's sacral spinous process extending from the upper edge toward the lower edge at the center in the width direction. Is formed. The depth of the longitudinal groove 3 is preferably 0.5 to 1.5 cm. The abutment surface 2A of the sacral support tool 2 is also cut at both upper sides thereof to form posterior superior iliac spine support surfaces 4A and 4B for supporting the user's posterior superior iliac spine. The depth of each posterior superior iliac spine support surface 4 is preferably 0.5 to 2 cm.

The operation of the sacral support tool 2 having the above structure will be described.
When using the sacral support tool 2, for example, as shown in FIG. 4, the user sits on the seat surface S of the chair, and the sacral spinous process in the longitudinal groove 3 and the posterior superior iliac spine in the posterior superior iliac bone. The contact surface 2A of the sacrum support tool 2 is applied to the mid-sacrum so as to be positioned on the spine support surfaces 4A and 4B, respectively. In this state, the back surface of the sacrum support tool 2 facing the contact surface 2A is a chair. Press against the back plate BR. Then, the pelvis is tilted forward, and the lumbar vertebra is held in the forward posture, thereby preventing and improving the lumbar vertebral disorder. Moreover, since the posterior superior iliac spine is supported by the posterior superior iliac spine support surfaces 4A and 4B, excessive movement of the sacroiliac joint can be suppressed.

  FIG. 5 shows a sacral support 20 that is a first modified embodiment of the sacral support 2. The sacral support tool 20 is different from the sacrum support tool body 2 only in that the back surface is configured as a convex curved surface.

  FIG. 6 shows a sacral support tool 30 which is a second modified embodiment of the sacral support tool 2. The sacrum support tool 30 differs from the sacrum support tool 20 only in that a cushioning material 31 is attached to the contact surface 2A of the sacrum support tool 20. By providing the buffer material 31, the pressure applied to the sacrum portion when the sacral support tool 30 is pressed against the back plate BR of the chair can be dispersed.

  The material of the buffer material 31 may be any material that can disperse the pressure, and any material used as a buffer material for existing medical devices such as resin such as foamed polyurethane and foamed polyethylene, rubber, and the like can be used. The thickness of the buffer material 31 is preferably 0.5 to 1.5 cm.

FIG. 7 shows a sacral support 1 that is a third modified embodiment of the sacral support 2.
The sacrum support tool 1 has the same sacrum support tool body 2 as the sacrum support tool 2 and a belt holder 10 attached to the back surface facing the abutting surface 2A, for example, with an adhesive. Of course, instead of the sacral support tool 2, a sacral support tool body having the same structure as the sacral support tools 20 and 30 can be used.
Belt insertion holes 11A and 11B penetrating the belt holding body 10 in the front-rear direction are formed in the respective side portions of the belt holding body 10, and the belt 12 is passed through these belt insertion holes 11A and 11B.

  The belt 12 includes fastening means for holding the belt 12, and thus the entire sacral support 1, to the user, and in this embodiment, a hook-and-loop fastener 12A that releasably engages each end of the belt 12, 12B is provided. The belt 12 may be made of elastic rubber. Also, instead of the hook-and-loop fasteners 12A and 12B, any known fastening means that can be releasably engaged with each other, for example, one or more belt holes formed at one end of the belt 12 A hook provided at the other end of the belt 12 that can be engaged with the belt hole may be used.

  When using the sacral support tool 1, the user places the sacral spinous process in the longitudinal groove 3 and the posterior superior iliac spine on the posterior superior iliac spine support surfaces 4A and 4B, respectively. The abutment surface 2A of the main body 2 is applied to the sacrum midline, and then the surface fasteners 12A and 12B of the belt 12 are engaged to attach the sacrum support 1 to the user.

  In this state, as shown in FIG. 7, when the user presses the sacral support 1 against the back plate BR of the chair while sitting on the seat surface S of the chair, the pelvis is tilted forward and the lumbar vertebra is It is held in a heel posture, thereby preventing and improving lumbar spine disorders. Moreover, since the posterior superior iliac spine is supported by the posterior superior iliac spine support surfaces 4A and 4B, excessive movement of the sacroiliac joint can be suppressed. Moreover, since the sacral support tool 1 can hold | maintain the sacrum support tool 1 to a user with the belt 12, when pressing the sacrum support tool 1 against the backplate BR etc. of a chair, the sacrum support tool 1 is accidentally dropped off. There is no fear of it.

  FIG. 8 shows an example in which the sacral support 2 described above is applied to a chair.

  The chair generally indicated by reference numeral 40 in FIG. 8 has a seat 41 and a back plate 42 attached to the seat 41, and the sacral support 2 described above is attached to the back plate 42. .

  For attaching the sacral support tool 2 to the back plate 42, any existing fixing means such as a hook-and-loop fastener, a button, a hook, a double-sided tape, and an adhesive can be used. Further, the sacral support 2 may be formed integrally with the back plate 42. Furthermore, you may attach the shock absorbing material 31 demonstrated in relation to FIG. 6 to the contact surface 2A of the sacral support tool 2. FIG.

  When using the chair 40, the user sits down on the seat 41, supports the sacral spinous process in the longitudinal groove 3 of the sacral support body 2, and supports the posterior superior iliac spine in the posterior upper iliac spine of the sacrum support body 2. The median sacrum is pressed against the abutment surface 2A of the sacral support body 2 so as to be positioned on the surfaces 4A and 4B, respectively. Then, the pelvis is tilted forward, and the lumbar vertebra is held in the forward posture, thereby preventing and improving the lumbar vertebral disorder. Moreover, since the posterior superior iliac spine is supported by the posterior superior iliac spine support surfaces 4A and 4B, excessive movement of the sacroiliac joint can be suppressed. Since the sacral support tool 2 is provided on the back plate 42, the sacrum support tool 2 does not fall off during use, and anyone can use it easily.

  FIG. 9 shows an example in which the sacral support 2 described above is applied to a leaning structure.

  A standing structure 50 generally designated by reference numeral 50 in FIG. 9 has a support plate 51 and the sacral support 2 described above attached to the support plate 51.

  The sacral support tool 2 can be attached to the support plate 51 by using any existing fixing means such as a hook-and-loop fastener, a button, a hook, a double-sided tape, and an adhesive. You may do it. Furthermore, you may attach the shock absorbing material 31 demonstrated in relation to FIG. 6 to the contact surface 2A of the sacral support tool 2. FIG.

  When the leaning structure 50 is used, the leaning structure 50 is leaned against the back plate of the chair. The standing structure 50 has an advantage that it can be supported by the seat of the chair and the upper portion of the back plate even when there is no support member (open structure) in the lower portion of the back plate of the chair. Similarly, a soft chair such as a sofa can be supported by the sofa seat 52 and the upper portion of the back plate 53 as shown in FIG.

After the leaning structure 50 is leaned against the chair in this way, the user sits on the seat of the chair, the sacral spinous process in the longitudinal groove 3 of the sacral support tool 2, and the posterior superior iliac spine in the sacral support tool body 2 The median sacrum is pressed against the contact surface 2A of the sacrum support 2 so as to be positioned on the posterior superior iliac spine support surfaces 4A and 4B, respectively. Then, the pelvis is tilted forward, and the lumbar vertebra is held in the forward posture, thereby preventing and improving the lumbar vertebral disorder. Moreover, since the posterior superior iliac spine is supported by the posterior superior iliac spine support surfaces 4A and 4B, excessive movement of the sacroiliac joint can be suppressed. Since the sacral support tool 2 is provided on the support plate 51, the sacrum support tool 2 does not fall off during use, and anyone can use it easily.
The present invention is not limited to the above-described embodiment, and various modifications can be made.
