Description

  The present invention relates to a cervical spine correction pillow used for cervical spine correction and posture correction.

  A conventional cervical vertebra correction tool (Patent Publication 2001-178755) is a rectangular parallelepiped having elasticity, and the head is placed on the occipital drop part formed in a groove penetrating in the central longitudinal direction, and the neck is placed on the neck receiving part. The cervical vertebrae were stretched by the weight of the milky protuberance 7 as a fulcrum, the chin raised, the head rotated, and the neck lowered, but this is insufficient in practice.

  The cervical spine forms a fold (physiological forehead) to support the heavy head at the back, but from the poor posture with reduced activity and forward tilt of daily life, the cervical vertebral curve (withstanding the weight of the head) Physiological outpost) decreases, leading to neck pain, stiff shoulders, insomnia, autonomic insufficiency, etc. When the anteversion posture of the cervical vertebra becomes a habit, the cervical atlantoaxial joint (the first cervical vertebra and the second cervical vertebra) moves forward and downward, induces the anterior movement of the lower cervical vertebra, and is straight from the decrease in curvature (physiological lordosis) Move to the neck.

  The straight neck is not a disease name but X-rays show that there are diseases such as cervical spondylosis, and in addition to anti-inflammatory analgesics and external medicine, symptomatic treatment such as cervical traction and hyperthermia was the main treatment, and there was no such treatment . Further, straight neck correction is important from the viewpoint of maintaining a physiological lordosis of the cervical spine, and the development of a cervical spine correction pillow has been demanded.

  Conventional pillows were commercialized based on the concept of a pillow that suits everyone, so the size standards were rough.

  Holding the cervical curvature requires the extended (backward bent) position of the head (occipital bone) and the cervical vertebra, and the conventional technique of extending the cervical spine by lowering the occipital position in the supine position is insufficient.

  Further, the conventional technique cannot restore the cervical vertebral array distortion caused by a bad anteversion posture in the lifestyle to the original anatomical state, and cannot maintain the physiological lordosis of the cervical vertebra.

  In addition, the structure of the cervical spine correction pillow is one-piece, and it could not meet the needs for maintenance and adjustment of the pillow height of the user.

JP 2001-178755 A

  Although it is very difficult for the human body to maintain the correct posture (physiological lordosis) that makes the spine draw a gentle S-shape, use a cervical spine correction pillow to prevent the tendency of cervical curvature to decrease It is necessary to rest the strained joints and muscles by overfilling the gap between the occipital region and the cervical region in a posture that raises the jaws slightly at bedtime and secures the airway and maintains the physiological lordosis of the cervical spine.

There are two heights for selecting the pillow height, and it is important to determine the height of the occipital region and the cervical arch. Anatomically, the length from the occipital region to the seventh cervical vertebra, the size of the occipital region, and the unevenness of the cervical vertebra portion are determined, so a pillow shape suitable for these conditions is required.
There is also a historical fact that we Japanese have traditionally used higher pillows. In other words, to use a higher pillow, it is necessary to pull the chin and place the head on the pillow, but this position compresses the airway and induces a straight neck, which impairs the normal cervical lordosis.

  It is anatomically reasonable to correct the cervical vertebral curvature with a pillow at bedtime to correct the physiologic anteversion of the cervical spine.

  A rational method for forming a physiological lordosis of the cervical spine is to lift the cervical vertebra with the third cervical vertebra as a fulcrum, and to extend the upper cervical vertebra and lower cervical vertebra with a range of motion in a radial and arcuate manner.

  Conventional cervical spine correction pillows fill the gap between the back of the head and neck, and the feeling of use is good, but the problem is that a soft low-resilience material is used, so there is no skeletal support of the back of the head and neck and the cervical spine is sinking The cervical curvature could not be corrected.

  Conventional cervical vertebral correction pillows are generally used on one side, and a double-sided cervical vertebral correction pillow that can select the height of the pillow and the hardness of the pillow is also required to meet the user's usage needs .

  In addition, since the cervical spine correction pillow lifts the cervical vertebra from below to hold the physiological lordosis, it is necessary to prevent unpleasant pressure on the external occipital protuberance and the cervical spine and to improve the usability.

  In order to hold the cervical vertebral curvature, a cervical facet joint receiving part must be provided on the cervical slope so that the cervical vertebra is not burdened when the cervical vertebra is lifted from below.

  When a cervical spine correction pillow is used in the lateral position, it is also necessary to develop a pillow with less ear compression. Moreover, it is necessary to make the pillow height parallel to the bed and the cervical spine.

  In addition, it is necessary to adjust the height of the pillow corresponding to aging such as changes in the pillow and physique of the person being used, etc., and the height adjustment of the cervical vertebra is easy, maintenance is possible, and the pillow that is friendly to the natural environment It has been demanded.

  In addition, since most pillows are formed of a resilient body and bonded together, the height of the pillow cannot be adjusted, and the air cushioning ability of the elastic body capable of intake and exhaust is impaired.

  Furthermore, since the size of the occipital region varies depending on the shape and size, it is necessary to adjust both sides of the occipital side support portion so that it can be opened and closed in order to adapt to various needs.

  The upper surface of the elastic body must be covered with a softer elastic body than the core forming portion of the elastic body.

  To protect the thin and special shape of the crown of the cervical spine correction pillow, it is necessary to cover it with leather.

  An object of the present invention is to solve these problems. An elastic body that holds the extended (backward bent) position of the cervical vertebra by lifting the upper cervical vertebra with a cylindrical elastic body and forms a head support. There is a downwardly-shaped truncated hemispherical hole that fits the occipital region from the center of the upper surface of the body to the center of the flat part on the posterior surface. An object of the present invention is to provide a cervical spine correction pillow that can be easily used at home to improve neck pain, stiff shoulders, insomnia, etc.

  In order to achieve the above object, the present invention has a triple cylindrical elastic body on the front side of the upper surface of the elastic body forming the cervical vertebra lifting portion, and the core portion has a pair of both sides of the elastic body of the cylindrical cavity. A rubber tube is provided, a lateral cavity is provided in the center, and the outer periphery is formed of a double cylindrical elastic body, and a removable tibial lifting cylindrical pad is provided in the lateral cavity in the central part of the cylindrical elastic body. The upper surface of the elastic body has a curved surface that faces upward from the front side to the center side, and a longitudinal longitudinal groove is formed along the center line from the front side of the cervical slope portion, and a cervical facet joint is provided on both sides of the upper surface of the longitudinal groove. It consists of means provided with a receiving part.

  Here, as a preferred embodiment, there is a downwardly truncated truncated semi-spherical hole that fits the back of the head from the center side of the upper surface of the elastic body forming the head support part to the center of the flat part on the back side, and the back of the head is in the hole recess. A support portion was provided, and a pair of movable occipital side support portions were formed on both sides of the occipital support portion. The upper surface of the elastic body is covered with an elastic body softer than the core of the elastic body, and the surface of the pillow of the elastic body is covered with leather.

The present invention can restore the original anatomical state of the distortion of the cervical vertebra array and the decrease of the cervical vertebral curvature caused by the bad anteversion posture in the lifestyle, and can maintain the physiological lordosis of the cervical vertebra.
In addition, a viscoelastic shock absorber was used as a core material for forming a physiological forehead and a neck curvature.

As described above, 50% of cervical extension (backward bending) and bending (forward bending) movements are performed between the occipital bone and the atlas (vertical vertebra), and the lower cervical vertebra has a fourth cervical vertebra. The fifth cervical vertebra is also significantly involved in the extension (backward bending) of the cervical vertebra. Therefore, the cervical vertebra is lifted by a cylindrical elastic body with the third cervical vertebra as a fulcrum as a fulcrum, and the occipital-circular vertebra with the movable range (the first cervical vertebra) ) And lower cervical vertebra (4th cervical vertebra-5 cervical vertebra) are radially and arcuately extended for cervical curvature correction.
According to the present invention, when the cervical vertebra is placed on a cylindrical elastic body, the cervical vertebra is lifted with the third cervical vertebra as a fulcrum, and the occipital region is placed on the cervical slope portion and the occipital region support portion formed of a stretchable elastic shock absorber (polyurethane). The weight lowers the back of the head and raises the jaw, pulls the cervical vertebrae radially and arches, and stress acts to naturally warp and form a physiological forehead to return the cervical curvature to its original state.
The state before and after use of the straight neck when the correction force of the orthopedic vertebral pillow in the supine position was strengthened was verified by X-rays. As a result, when the inclination angle of each vertebra between the first cervical vertebra and the sixth cervical vertebra was measured, the total increased by 38 degrees. In addition, the length of the cervical arch at the leading edge of the vertebra between the first cervical vertebra and the seventh cervical vertebra increased by 4 mm, and the cervical tilt angle of the cervical vertebral physiological forehead increased by 3 degrees from 17 degrees to 20 degrees.
Further, when the head is viewed from the side, the center of gravity of the head is located at the Turkish anterior to the occipital condyle of the occipital bone, and the fulcrum is at the position of the occipital condyle. In other words, the center of gravity of the head is located forward and the first cervical vertebra (annular vertebra) moves forward and downward with respect to the second cervical vertebra (axial vertebra) during forward bending. However, it also has the effect of improving the balance of the head on the cervical vertebra by raising the cervical vertebra and lowering the head as described above.
Further, in terms of kinematic movement, when the occipital bone extends with respect to the first cervical vertebra (annular vertebra), the occipital condyle slides forward on the atlas and the occipital bone approaches the posterior arch of the atlas. The atlantoaxial joint is also extended so that the atlas posterior arch and the posterior arch are approached.

The cylindrical elastic body serves as a fulcrum for the cervical vertebra lifting portion of the third cervical vertebra, and is necessary for maintaining the extended (backward bent) position of the cervical vertebra and the occipital region.

  In addition, a cylindrical elastic body is provided on the front surface side of the upper surface of the elastic body, an upwardly curved surface is formed from the front surface side to the rear surface side of the upper surface of the elastic body, and a lateral cavity ( Holes are arranged, and a longitudinal groove (hole) is provided in the longitudinal direction along the center line from the front side.The lateral cavity relieves pressure on the spinous process of the lower cervical spine, and the outer occipital protuberance is located in the center of the longitudinal groove of the cavity. -The cervical spine process is accommodated, and the cervical facet joint receiving portions are provided at both ends of the longitudinal groove and lateral cavity, so that the cervical curvature (physiological lordosis) is corrected by holding the cervical part comfortably.

Since the core of the cylindrical elastic body has a pair of rubber tubes on both sides of the cavity and a transverse cavity in the center, it is easy to adjust the user's needs for various pillow heights.
In addition, the correction force for cervical vertebral curvature increases as the length of the lateral cavity by the rubber tube decreases.

  The width adjustment of the lateral cavity provided in the cylindrical core can be performed by adjusting a pair of rubber tubes on both sides. This makes it possible to adjust the cervical spine correction strength and the hard and soft feel of use. The correction force of the cervical vertebra can be strengthened by moving the rubber tubes on both sides to the center and eliminating the horizontal cavity, and the correction force of the cervical spine can be weakened by pulling the rubber tubes on both sides to provide the horizontal cavity.

  The rubber tube is an essential part of the cervical vertebra lifting portion, and improves the fit of the cervical arch portion during use, prevents the material from becoming loose, and is effective in ensuring the elasticity of the core portion.

  The slope of the cervical vertebra serves as a foundation for the convexity of the external occipital protuberance of the occipital bone and the spinous process of the cervical spine.

  An upward curved surface is formed from the front surface side of the upper surface of the elastic body toward the central side of the cervical slope portion, and the external occipital protuberance and cervical spinous protrusion are formed in a longitudinal longitudinal groove along the center line from the front surface side. Excellent fit because it was delivered.

  A curved surface that faces upward from the front side to the center side of the upper surface of the elastic body is provided, and a longitudinal vertical groove is provided along the center line from the front side of the cervical slope portion, and a cervical facet joint is received on both sides of the upper surface of the vertical groove. Since the portion is provided, the cervical spine can be held in a stable state without difficulty.

  When the cervical vertebral correction pillow is used in the lateral supine position, pulling the longitudinal groove and the rubber tubes on both sides to provide lateral cavities reduces the pressure on the ear and provides a soft feeling of use.

  A rubber tube is formed of a low resilience material in the horizontal cavity in the center of the cylindrical elastic body, and a removable tibia lifting cylindrical pad is provided, so the cervical arch of the cervical arch corresponding to the needs of the user can be selected by selecting the part size Easy height adjustment.

  In addition, since the outer peripheral side of the rubber tube is wound with a low resilience material in the lateral cavity, the contact with the vertebra is soft and the fit with the cervical vertebra is excellent.

  In addition, a removable tibial lifting cylindrical pad formed by winding the outer peripheral side of the rubber tube with low resilience material is inserted in the sideways cavity, but the diameter is smaller than the rubber tube adjacent to both sides When the pillow is used in a lateral position, there is less pressure on the ears and it feels good.

  It has a downward hemispherical hole that fits the back of the head from the center side of the upper surface of the elastic body forming the head support part to the center of the flat part on the back side, and has a characteristic of less muscular muscle in the recess of the hole A viscoelastic shock absorber was provided on the occipital support. Therefore, since the back of the head is supported with excellent dispersibility of body pressure, the back of the head fits and the head does not escape and the cervical vertebra sits well.

  Forms a head support part.There is a downwardly truncated head-like semispherical hole that fits the back of the elastic body from the center side of the upper surface of the elastic body to the center of the flat part on the back side. Since a pair of occipital side support portions that open to the left and right are formed on both sides of the unit, the occipital side can be adjusted according to the user's occipital size, so that the temporal region is also stable.

  This cervical spine correction pillow holds the gap between the cervical and occipital areas without a sense of incongruity, and the upper surface has moderate softness, and the core has the characteristics of muscles that can disperse a slightly firm body pressure to hold the cervical vertebral curvature. It is made of a viscoelastic shock absorber. This is quickly deformed when subjected to external pressure and slowly restores its original shape, thereby absorbing the impact and distributing the pressure uniformly by a high viscoelastic effect to gently fit the head and neck. Further, the elastic body is covered with a skin such as leather that has low hygroscopicity and is resistant to wear.

  As described above, the cervical spine correction pillow is formed by the cervical vertebra lifting portion, the cervical vertebra slope portion, and the head support portion. On the front side, the pillow height is low and the urethane is soft and suitable for winter. On the back side, the pillow height is slightly high and the urethane is slightly hard and suitable for summer.

  The structure of the elastic body has a cylindrical elastic body cervical lifting part, cylindrical pad part, cervical slope part, head support part in order to simplify the adjustment of the pillow height in consideration of assembly, maintenance and parts replacement. Consists of.

  In addition, in order to improve the air cushion and fit feeling that can be sucked and exhausted during use, the adhesion of the cylindrical elastic body cervical vertebra lifting part, cervical slope part, head support part part is a decomposable point adhesion Therefore, the pillow air is gently exhausted during use, giving a soft feel. When not in use, air is sucked and the original state is restored.

The pillow height is determined by determining the height of the cervical vertebra (arch) based on the height of the back of the head from the bed.
The height of the cervical arch in the supine position is about 3 cm for women and about 4 cm for men.
Furthermore, in consideration of the height of the back of the head, the diameter of the cylindrical elastic body was set to SS: 3.5 cm · S: 4.0 cm · M: 4.5 cm · L: 5 cm · LL: 5.5 cm.

  Therefore, it is optimal by setting the diameter of the cylindrical elastic body to SS: 3.5 cm · S: 4.0 cm · M: 4.5 cm · L: 5 cm · LL: 5.5 cm · LLL: 6.0 cm The pillow height can be adjusted to anyone.

  Medically, rheumatoid arthritis has atlantoaxial instability due to the relaxation of the transverse ligament of the atlantoaxial joint (the anterior arch of the atlas moves forward and downward relative to the dentate in the cervical flexion position). When an orthodontic pillow is used, the anterior arch can be corrected posteriorly with respect to the dental process, which is effective in preventing atlantoaxial instability in rheumatic patients.

  In addition, the cervical vertebra is tilted in the direction of the affected side with a piece of hemiplegia resulting from cerebrovascular disorder, but it is sagittal by placing the occipital region in the occipital support part in the cross section of the central lower part of the truncated hemispherical hole. Since the balance of the head on the cervical vertebra is improved, the correction and prevention of the torticollis are also effective.

  In addition, because the cervical vertebra is located in the front and the cervical vertebra in the skeletal structure, the head (the occipital condyle in the occipital bone is posterior) is moved forward by the rotation moment and the cervical vertebra (ring (Axial joint) induced a straight neck in the anterior and downward direction, which contributed to neck pain, stiff shoulders, and irritation, but by using the cervical spine correction pillow of the present invention, the physiological lordosis was restored and anatomical QOL (quality of life) is improved by returning to the correct position.

  The present invention relates to a cervical vertebra correction pillow used for cervical vertebra correction and posture correction. As another method of using the cervical vertebra correction pillow, by turning the cervical vertebra correction pillow upside down, two types of software and hardware can be selectively used. As described above, the surface of the elastic body is covered with a resilient body softer than the core, and the back of the head is placed in a recess of a substantially truncated hemispherical hole facing downward. Therefore, the pillow on the front side is low and the urethane is soft and suitable for winter, and the back side is slightly higher and the urethane is slightly hard and suitable for summer.

Hereinafter, the present invention will be described more specifically based on embodiments for carrying out the invention described in the drawings.
In the figure, the cervical spine correction pillow 1 pulls the cervical vertebra in a radial or arcuate manner to correct the curvature of the cervical vertebra by recovering the ideal cervical vertebral curvature, and safely improves cervical pain, stiff shoulders, stress, etc. It has features that can. The cervical spine correction pillow 1 has a cervical vertebra lifting portion 2 from the front side where the neck side, which is the longitudinal direction of the pillow, is supported, to the rear side where the occipital region is supported, in order to hold the cervical part and the occipital region without a sense of incongruity. The cervical vertebra slope part 3 and the head support part 4 are comprised.

  The cervical vertebra lifting part 2 has, for example, a triple cylindrical elastic body 21. The cylindrical elastic body 21 is arranged such that its core direction is in the width direction of the cervical spine correction pillow 1. That is, the cylindrical elastic body 21 is disposed sideways with respect to the cervical spine correction pillow 1. The cylindrical elastic body 21 has the center of the cylindrical portion as a fulcrum of the lifting portion of the third cervical vertebra, and the cervical vertebra extends radially from the upper cervical vertebra to the lower cervical vertebra. The cylindrical elastic body 21 lifts the cervical vertebra and holds the extended (backward bent) position of the cervical vertebra and the occipital region, so that cervical curvature can be corrected.

  The cylindrical elastic body 21 is provided with a pair of cylindrical rubber tubes 22 divided into the left and right sides at the center of the core, and the outer peripheral side of the rubber tube 22 is highly elastic wound in a softer cylindrical shape. Further, the outer peripheral side of the high-elastic sponge 23 is formed of a low-repulsion foam 24 wound in a cylindrical shape having a lower repulsion than this, and has a triple structure.

  The rubber tube 22 has a hollow inside. The rubber tube 22 is divided into two from the center to the left and right, and is composed of a pair of left and right. A pair of rubber tubes 22 on both the left and right sides can be pulled left and right. That is, the left and right rubber tubes 22 can be moved and adjusted in the left and right direction. This makes it possible to adjust the cervical spine correction strength and hard and soft feel. Moreover, the rubber tube 22 is an essential part of the cervical vertebra lifting portion 2 and also serves as a core member thereof, which improves the fit of the cervical arch portion during use, prevents the cylindrical elastic body 21 from being loosened, and has an appropriate elasticity. is doing.

  A cylindrical lateral cavity 25 is formed at the center where the pair of rubber tubes 22 on the left and right sides are separated. As described above, the lateral cavity 25 can be extended or shortened by pulling the rubber tubes 22 on both sides to the left and right as described above. The pair of rubber tubes 22 on both sides hold the lateral cavity 25 when the pillow is used, so that the feeling of use and comfort are improved by alleviating the feeling of pressure on the cervical spinous process, cervical facet joint, and cervical transverse process in the cervical arch. .

  A tibia-lifting cylindrical pad 26 is detachably inserted in the lateral cavity 25 whose size is adjustable. By changing the diameter of the inserted tibia lifting cylindrical pad 26, the cervical arch height can be easily adjusted to meet the needs of the user.

Because it is formed, it feels good. The diameter of the rubber tube 26a is slightly smaller than the diameter of the rubber tube 22 provided on the left and right sides of the cylindrical pad 26 for lifting the tibia, and the pressure on the ear can be reduced when the cervical spine correction pillow 1 is used in the lateral position.

  The outer peripheral side of the cylindrical elastic body 21 is covered with a soft rebound elastic material 27 that is the softest material of the cervical vertebra correction pillow 1 and wound around 70 to 80%. That is, the bottom surface side, the front surface side, and the top surface side of the outer peripheral side of the cylindrical elastic body 21 are covered with the low resilience elastic material 27. The low resilience elastic material 27 that covers most of the cylindrical elastic body 21 also covers the upper surface side of the cervical slope portion 3 and the tip thereof is in contact with the head support portion 4.

  The cervical slope part 3 serves as a base for accommodating the convex part of the outer occipital protuberance of the occipital bone and the spinous process of the cervical spine, and the upper surface side thereof is inclined obliquely downwardly toward the head support part 4. A hollow longitudinal groove 31 is formed in the center of the cervical vertebra slope portion 3 from the cervical vertebra lifting portion 2 toward the head support portion 4. Since the hollow longitudinal groove 31 accommodates the outer occipital protuberance and the cervical spine protrusion, the fit is excellent.

  Cervical facet joint receiving portions 32 are provided on both sides of the upper surface of the hollow longitudinal groove 31. Sitting of the cervical vertebra is improved by the longitudinal groove 31 of the cavity for accommodating the external occipital protuberance and the spinous process of the cervical spine and the cervical facet joint receiving portions 32 on both sides of the upper surface.

  The upper surface side of the cervical slope 3 is covered with a low resilience elastic material 27 extending from the cervical vertebra lifting portion 2 side, and a soft low resilience foam 33 is provided on the lower surface thereof. The low resilience foam 33 is not as soft as the low resilience elastic material 27.

  On the lower surface side of the low resilience foam 33, a viscoelastic shock absorber 34 having a slightly hard muscle characteristic is provided. One end of the viscoelastic shock absorbing material 34 is in contact with the outer peripheral side surface of the cylindrical elastic body 21, and the other end sinks into the lower side of the head support portion 4 so that the head support portion 4 extends from the lower side of the head support portion 4. It covers the whole area. For example, polyurethane is used for the viscoelastic shock absorber 34.

  On the lower surface side of the viscoelastic shock absorber 34, the vertical groove 31 is formed at the center thereof. Viscoelastic shock absorbers 35 are provided on both sides of the vertical groove 31. The viscoelastic shock absorber 35 is hardest than the viscoelastic shock absorber 34 on the upper surface side, and polyurethane, for example, is used as the material thereof. One end of the viscoelastic shock absorber 35 is in contact with the outer peripheral side surface of the cylindrical elastic body 21, and the other end is in contact with the head support portion 4 side gradually decreasing in thickness at a constant linear rate. Yes.

  The left and right inner side surfaces of the vertical groove 31 are formed by the inner side surfaces of the left and right viscoelastic shock absorbers 35. The vertical groove 31 is a so-called dovetail. Both left and right inner surfaces are inclined upward toward the inner side of the groove. The width of the upper surface of the vertical groove 31 is narrower than that of the lower surface of the groove. ing. The vertical groove 31 is closed on both the left and right side surfaces with left and right viscoelastic shock absorbers 35, the upper surface is closed with a viscoelastic shock absorber 34, and the lower surface thereof is closed with a low-rebound foam 36, which will be described later. It is formed in a cavity.

  Soft low-resilience foams 36 are provided on the lower surfaces of the longitudinal grooves 31 and the left and right viscoelastic shock absorbers 35. The low resilience foam 36 is made of the same material as the low resilience foam 33. One end of the low resilience foam 36 is in contact with the outer peripheral side surface of the cylindrical elastic body 21, and the other end side is in contact with the upper surface of the head support portion 4 side that is thinned in a stepped manner.

  As described above, this cervical vertebra correction pillow 1 has a cylindrical elastic body 21 with a hollow core portion, a pair of rubber tubes 22 provided on both sides of the hollow core portion, and a lateral cavity 25 of the central hollow portion. The length in the width direction is adjustable, and the longitudinal groove 31 and the lateral cavity 25 of the cavity are formed, so that the compression of the cervical vertebra protrusion during use is relieved, and when used in the lateral supine position, the ear is compressed. Relaxed and soft fit is obtained. Further, the gap between the cervical vertebra and the occipital region is eliminated, and the cervical vertebra can be sat on without adapting to the shape and the head does not escape.

  The head support portion 4 supports the occipital portion by a hole 41a of the occipital support portion 41 formed at the center of the upper surface of the elastic body, and the hole 41a is formed in a substantially hemispherical shape facing downward. The hole 41a is a straight line parallel to both ends in the length direction of the cervical vertebra correction pillow 1 when viewed from the plane, and both sides on the middle side are arcs. That is, the truncated hemispherical hole 41a has a larger hemispherical diameter on the lower side, and the top side of the forged hemispherical is cut in the middle to form a circular hole with a smaller diameter. The truncated hemispherical hole 41a has a circular diameter smaller on the upper side than on the lower side. Further, the truncated hemispherical hole 41a has such a shape that both ends in the length direction of the cervical spine correction pillow 1 are cut in a direction perpendicular to the length direction. The occipital region does not escape by the hole 41a of the occipital support portion 41, and the cervical spine can be sat down. On the left and right sides of the hole 41a of the occipital support portion 41, occipital side support portions 42 made of the same soft material as the low-repulsion elastic material 27 and made of the softest low-repulsion elastic material are provided. By widening or narrowing the interval between the left and right occipital side support portions 42, the size of the pillow user's head can be adjusted.

  On the lower surface side of the left and right occipital side support portions 42, high elasticity sponges 43 are similarly provided, each having a lower side of the hole 41a at the center. The high elastic sponge 43 has the same hardness as the high elastic sponge 23 of the cylindrical elastic body 21. Low resilience foams 44 are respectively provided on the lower surfaces of the left and right high-elastic sponges 43. On the bottom surface of the hole 41a, the softest low-repulsion elastic material 45 is provided in the same manner as the low-repulsion elastic material 27.

A harder elastic material 46 is provided next to the viscoelastic shock absorber 34 on the lower surface side of the viscoelastic shock absorber 34 that is directly below the left and right low resilience foams 44. A back surface hole 47 is formed directly below the hole 41a with the low resilience foam 44 and the viscoelastic shock absorber 34 interposed therebetween. The back hole 47 is formed in the center of the elastic material 46. When the back hole 47 is used with the cervical spine correction pillow 1 turned over, the back head 47 is placed and stabilized in the same manner as the hole 41a.

  A high-elastic sponge 5 having the same hardness as the high-elastic sponge 23 of the cylindrical elastic body 21 is wound around the outer periphery of the cervical vertebra lifting portion 2, cervical vertebra slope portion 3, and head support portion 4 described above. Yes. The highly elastic sponge 5 surrounds all of the front side, the top side, the rear side, and the bottom side of the cervical vertebra correction pillow 1. The surface of this cervical vertebral correction pillow 1 is covered with leather 6 that is less hygroscopic and resistant to wear.

Next, a method of using the cervical spine correction pillow based on the configuration of the embodiment for carrying out the invention will be described below.
The rear side of the neck is placed on the upper side of the cylindrical elastic body 21 of the cervical vertebra lifting part 2 of the cervical vertebra correction pillow 1, the back of the head is placed in the hole 41 a of the back of the head support 41, and the lower back of the head is placed on the upper side of the cervical slope 3.
In this way, when the cervical vertebra is placed on the cylindrical elastic body 21 in the supine position and the cervical vertebra is lifted and the occipital region is placed in the hole 41a of the occipital support portion 41, the occipital region is lowered by the weight of the head, the chin is raised, and the cervical vertebra is radial and arcuate. As a result, the cervical vertebra is arranged and the neck arch is formed in the cervical vertebra lifting portion 2 and the cervical vertebra slope surface portion 3, so that the cervical curvature can be corrected and held while fitting and sleeping.
Further, the lower cervical spine can be corrected by the cylindrical elastic body 21 by moving the cervical spine correction pillow 1 downward and moving the occipital region onto the occipital support unit 41.
Furthermore, as another method of using the cervical vertebra correction pillow 1, by turning the cervical vertebra correction pillow 1 upside down, it is possible to select and use two surfaces, soft and hard. As described above, the elastic body surface is covered with an elastic body softer than the core portion, and the occipital region is placed in the recess of the downwardly truncated hemispherical back surface hole 47, and the back surface is close to the core member and the back surface of the occipital support portion 41. Since the hole 47 is also smaller, the pillow on the front side is lower and the urethane is softer for winter, the pillow on the back is slightly higher, the urethane is slightly harder, and the summer specification.
The height of the cervical arch is determined based on the height of the back of the head from the bed, and the size of the pillow is determined. In addition, the height of the cervical arch in the supine position is about 3 cm for women and about 4 cm for men. In consideration of the height of the back of the head, the diameter of the cylindrical elastic body 21 is optimally set to SS: 3.5 cm, S: 4 cm, M: 4.5 cm, L: 5 cm, LL: 5.5 cm Anyone can easily adjust the pillow height.

  It should be noted that the present invention is not limited to the mode for carrying out the above-described invention, and various modifications can be made without departing from the spirit of the present invention.
