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 No. 2011-167325) is a rectangular parallelepiped having elasticity, and the head is placed on the occipital depression formed in the groove penetrating in the central longitudinal direction, and the neck is placed on the neck receiving part. The chin was raised and the cervical vertebra was extended with the milky procession portion as a fulcrum by the weight of the part, but this is insufficient for practical use.

The cervical spine forms a fold (physiological forehead) to support the heavy head at the back, but the cervical fold is unable to withstand the weight of the head because of poor posture with decreased daily activities and forward tilt. (Physiological outpost) decreases, leading to neck pain, stiff shoulders, insomnia, autonomic ataxia, etc. When the anteversion posture of the cervical spine becomes customary, the cervical atlantoaxial joint (first cervical vertebra and second cervical vertebra) moves forward and downward, and induces forward movement from the upper cervical vertebra (first cervical vertebra and second cervical vertebra) to the lower cervical vertebra From the decrease of cervical vertebral curvature (physiological lordosis) to the straight neck.

Many people have recently been using high pillows, but the position of raising the back of the head and pulling the chin compresses the airway and induces a straight neck, which can damage the normal anteversion of the normal cervical spine.
In view of the anatomical shape of the occipital region, the length of the seventh cervical vertebra from the occipital region and the situation of the cervical curvature, a pillow height and shape suitable for these states are required.

The straight neck was not a disease name but X-rays were taken, and there were diseases such as cervical vertebral flattening and cervical spondylosis. Treatment was mainly symptomatic treatment such as analgesics, cervical vertebral traction, and thermotherapy, and there was no such treatment. In addition, 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 there was no standard for pillow size and the standards were broad.

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

In addition, the structure of the cervical spine correction pillow was integrated, and could not meet the needs for maintenance and adjustment of the pillow height of the user.

In order to maintain the curvature of the cervical spine, it is necessary to adjust the load distribution of the cervical part in consideration of the balance between the height of the occipital region from the bed and the height of the cervical arch.

Japanese Patent Publication No. 2011-167325

Although it is very difficult for the human body to maintain the correct posture (physiological lordosis) so that the spine draws a gentle S-shape, use a cervical spine correction pillow to prevent the decrease in cervical curvature. At bedtime, it is necessary to raise the jaws slightly to secure the airway and maintain the physiological lordosis of the cervical vertebrae, fill the gap between the occipital region and the cervical region, and use the strained joints and muscles.
Conventional pillows are poorly designed to retain the neck's physiological forehead and form a cervical arch, and multiple low-resilience sponges are bonded and fixed, making it difficult to change the material when adjusting the pillow height. It took time to replace the bone pillow to adjust the height, and the low resilience sponge had problems such as stuffiness in summer. Also, the pillow size standard was ambiguous and the neck arch height was ignored.

It is anatomically reasonable to correct the cervical vertebral curvature with a pillow at bedtime to correct the physiologic anterior cervical vertebrae.

The rational method of forming a physiologic lordosis of the cervical spine is the upper cervical vertebra (first cervical vertebra-second cervical vertebra) with lower range of movement, with the cervical vertebrae lifted around the second cervical vertebra and the third cervical vertebra as fulcrums. It is necessary to stretch the cervical vertebra (the third cervical vertebra to the seventh cervical vertebra) radially and in an arcuate shape.

The problem with conventional pillows for cervical spine correction is that the gap between the occipital region and the cervical region is filled with a soft low-resilience material. I was unable to correct and maintain the cervical curvature.

  Urethane, which is the mainstream of cushioning, is easily repelled while being highly repellent, and there are also problems in terms of air permeability and environmental safety. There is a need for environmentally friendly materials that can be recycled.

In addition, the orthopedic pillow for cervical vertebra lifts the cervical vertebra from below to hold a physiological forehead, so it is necessary to prevent uncomfortable pressure on the pillow, the external occipital protuberance, and the spinous process of the cervical spine to enhance the usability.

In order to hold the cervical vertebral curved portion, a cervical intervertebral joint receiving portion must be provided in the cervical vertebra so that the cervical vertebra is not burdened when the cervical vertebra is lifted in an arch shape from below.

When the cervical spine correction pillow is used in the lateral position, it is also necessary to select a material 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 pillow height corresponding to aging, such as the annual body shape change of the cervical curvature of the person used, it is easy to change the height of the cervical spine by assembling, easy to change the height of the cervical spine There is a need for pillows that are good in nature, easy to maintain, and friendly to the natural environment.

  There is currently no basic setting standard for pillow size, so it is also necessary to evaluate and determine the average value of the neck arch (cervical vertebra arc).

It is necessary to consider the pillow height adjustment and maintenance by making the surface of the material of the core part as an assembly type instead of the pillow structure.

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

The present invention is intended to solve these problems, and an elastic body that forms a head support portion by holding the extended (backward bent) position of the cervical vertebra by lifting the upper cervical vertebra with a cylindrical elastic body. There is a downwardly truncated truncated semi-spherical hole that fits the occipital region from the center side of the upper surface to the flat central part on the posterior surface side, and a cervical vertebral curve is formed by placing the occipital support part in the hole recess and storing the occipital region The purpose 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 solve the above problems, 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 is paired on both sides of the elastic body of the cylindrical cavity. The rubber tube is inserted, a lateral cavity is provided in the center, and the outer periphery is double-cylindrically formed of an elastic body. The lateral cavity in the central part of the cylindrical elastic body has a pocket and is removable. A cylindrical bud for lifting the cervical bone, providing an upward curved surface from the front side to the center side of the upper surface of the elastic body, and providing a longitudinal longitudinal groove along the center line from the front side of the cervical vertebra slope part, A cervical facet joint receiving portion is provided on both sides of the upper surface of the longitudinal groove, and a stepped slope portion is provided on the lower surface of the cervical facet joint receiving portion.

Here, as a preferable aspect, the head has a substantially hemispherical hole with a downwardly truncated face 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. A support portion was provided, and a pair of occipital side support portions were formed on both sides of the occipital support portion.
Further, a fusion (solid knitted fabric) excellent in air permeability and body pressure dispersion was provided on the upper part of the hemispherical hole, and breath air (reticulated elastic body) was formed on the occipital side support portion.

The present invention is based on the anatomical distortion of the cervical vertebrae array caused by a bad anteversion posture in lifestyle, the decrease in cervical curvature (flattening of the cervical vertebrae), and the inclination of the cervix (oblique neck). The physiological lordosis of the cervical vertebra can be maintained by returning to the state.
In addition, since the viscoelastic shock absorber is used for the core material forming the physiological lordosis and the cervical vertebral curve, it can be used without a sense of incongruity.
New material fusion (three-dimensional knitted fabric) is provided on the cervical vertebra lifting part and cervical slope part of the core structure forming the neck arch, and breath air (net-like elastic body) is provided on the occipital side support part and fixed with two strings Since the parts are assembled with pillows, the work process is shortened, and the side cavity of the cylindrical pad storage part that adjusts the pillow height is made a removable pocket type, so replacement of pillow height parts However, it is possible to provide a pillow for cervical vertebra correction that can relieve stuffiness in summer because it uses a new material of breath and breath air that is easy to breathe and disperses body pressure.

As described above, 50% of the movements of cervical extension (backward bending) and flexion (forward bending) are performed in the upper cervical vertebra (first cervical vertebra-second cervical vertebra) and the lower cervical vertebra (third cervical vertebra-third vertebra). (7 cervical vertebrae) is also significantly involved in cervical vertebra extension (backward bending) and flexion (forward bending), so the cervical vertebrae are lifted with a cylindrical elastic body around the 2nd to 3rd cervical vertebrae with a small range of joint motion, Extending the upper cervical vertebra (first cervical vertebra vertebrae to the second cervical vertebra) and the lower cervical vertebrae (third cervical vertebrae to the seventh cervical vertebra) having a remarkable range of motion is rational for correcting the cervical vertebral curvature.
According to the present invention, when the occipital region is placed on the occipital region support part and the user raises his / her chin, it is cylindrical with the cervical vertebrae to the third cervical vertebrae as fulcrums while maintaining the physiological lordosis of the cervical vertebrae. The elastic body holds the cervical vertebrae, and the weight of the head and cervix slowly lowers the cervix from the back of the head, and the lifting force acts on the cylindrical elastic body and the cervical vertebral slope to naturally extend the cervical vertebrae radially and arched Warping occurs, a physiological lordosis is formed, and the cervical curvature can be returned to its original state.
The condition of the tibia before and after use of the straight neck when the corrective force with the cervical spine correction pillow in the supine position was slightly increased was verified by X-ray.
As a result, when the inclination angle of each vertebra in the first cervical vertebra to the seventh cervical vertebra was measured, the angle increased by 38 degrees in total. In addition, the length of the cervical arch at the entire vertebra of the first cervical vertebra to the seventh cervical vertebra is increased by 2 mm to 3 mm.
Furthermore, the balance of the head on the cervical vertebra is such that when the head is viewed from the side of the sitting position, the center of gravity of the head is located in the Turkish anterior to the occipital condyle of the occipital bone, and the fulcrum is posterior to the occipital condyle of the occipital bone. is there. Therefore, since the center of gravity of the head is in front of the cervical vertebra, when anterior-lower stress acts on the median atlantoaxial joint during forward bending, the vertebra (first cervical vertebra) undergoes a “nodding motion” and turns into the axial vertebra (second cervical vertebra). As a result, a chain of “nodding movement” occurs, resulting in flattening of the physiological forehead. As described above, the occipital support is placed in the occipital support, the cervical vertebra is lifted with a cylindrical elastic body, and the physiologic forehead of the cervical vertebra is Holding it also has the effect of improving the balance of the head on the cervical spine.

In order to maintain the physiological lordosis of the cervical vertebra, it is necessary to adjust the balance between the height of the occipital region and the height of the cervical arch from the bed in consideration of the burden on the cervical vertebra. Incidentally, the weighted distribution of the back and neck of a typical memory foam pillow is 9: 1. Therefore, looking at the average value of cervical vertebra arch height by sex, we studied the weighted distribution of the occipital region and the cervical region of 3cm female and 4cm male, and found that the ratio of 6: 4 was optimal.

In addition, it is necessary to adjust the holding of the cervical arch suitable for pain symptoms of the cervical spine.
For those with significant neck pain, the weighted distribution of the occipital region and cervical spine is 7: 3. If the cervical spine is sensitive and cervical pain is prominent, the weight distribution 8: 2 between the occipital region and the cervical vertebra with the cervical spine lifting cylindrical pad removed is suitable.

In addition, by carrying out the present invention and maintaining a physiological forehead, atlas occipital joint, atlantoaxial joint (median atlantoaxial joint, lateral atlantoaxial joint), intervertebral joint slip, intervertebral disc cushion, joint range of motion Will improve.

The cylindrical elastic body raises the neck, rotates the head, lowers the head, and is required to hold the extended (backward bent) position between the back and neck.

Further, a cylindrical elastic body is provided on the front surface side of the upper surface of the elastic body, an upward curved surface is formed from the front surface side to the rear surface side of the upper surface of the elastic body, and a horizontal cavity ( Cylindrical lifting pad with detachable tibia with holes in the cavity and holes for cervical spine in the longitudinal direction along the center line from the front side. The cervical vertebrae are maintained with a vertebral vertebrae, and the height of the pillow is also adjusted. Since a facet joint was provided and a stepped slope was provided on the lower surface of the cervical facet joint receiver, the neck could be held without any discomfort and the curvature of the neck (physiological forehead) could be corrected.

By providing a detachable pocket in the lateral cavity (hole) in the center of the cylindrical elastic body, the tibial lifting cylindrical pad can be easily replaced.

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 cervical slope is the foundation for holding the cervical spine.

The upper surface of the elastic body is curved upward from the front side toward the center side, and the outer occipital ridge and cervical spinous protrusion are fitted in the longitudinal groove of the cavity along the center line from the front side. Excellent feeling.

The upper surface of the elastic body has an upward curved surface from the front side toward the center side, a longitudinal longitudinal groove is provided along the center line from the front side of the cervical slope part, and the cervical facet joints are provided at both ends of the upper surface of the longitudinal groove. Since the receiving part is provided and the stepped slope part is provided on the lower surface of the cervical facet joint receiving part, the cervical part can be held in the longitudinal groove of the cavity along the center line in a stable and reasonably stable state. Sitting in is good.

The cylindrical elastic body has a pocket in the lateral cavity, a low-rebound material is made of viscoelastic shock absorber, and a removable tibial lifting cylindrical pad is provided, so the pillow height can be adjusted by changing the part size It was easy.

Moreover, since the low repulsion material is formed of the viscoelastic shock absorber in the lateral cavity, the contact with the vertebra is soft and the cervical vertebra fits well.

Since the central part of the pillow is recessed, when the pillow is used in the lateral position, there is less pressure on the ears and it feels good.

The head has a downwardly-shaped truncated hemispherical hole that fits the back of the head from the center of the upper surface of the elastic body forming the head support portion to the center of the flat portion on the rear surface, and has excellent breathability and body pressure dispersion at the top of the hole. A fusible (three-dimensional knitted fabric) that can be recycled friendly to the environment is provided on the back support part. Accordingly, since the occipital region is supported by pressure-resistant dispersibility, the occipital region fits and the occipital region does not escape and the cervical spine sits well.

There is a downward hemispherical hole that fits the back head in the center of the flat part on the rear surface side from the center side of the upper surface of the elastic body forming the head support part, and a fusion (three-dimensional knitting) is formed in the recess above the hole. Since the occipital support part is provided and a pair of occipital side support parts are formed on both sides of the occipital support part, the user's occipital and temporal areas are also stabilized.

The occipital side support part uses moderately thick breath air (reticulated elastic body) that has light weight, high resilience, breathability and supportability.

This cervical vertebral pillow uses a fusion (solid knitted fabric) and breath air (reticulated elastic body) that are breathable and have excellent body pressure dispersion to maintain the gap between the cervical and occipital bones. The cervical core is formed of a viscoelastic shock absorbing material having the characteristics of a muscle that can withstand a slightly hard pressure to disperse the cervical vertebral curve. This is because when it receives external pressure, it slowly deforms and slowly restores its original shape, absorbs the impact and distributes the pressure evenly with a high elastic effect, so the back of the head fits and the head does not escape and the cervical spine sits good.
The elastic body was covered with a hygroscopic cloth.

As described above, the cervical pillow was formed with the cervical vertebra lifting part, cervical vertebra slope part, head support part,
You can select and use either soft or hard. The front pillow height is low and soft, and the back pillow height is high and hard.

The structure of the elastic body has a cervical vertebra lifting part, cervical vertebral slope part, and head support part in the core structure in order to simplify the adjustment of the pillow height in consideration of maintenance and replacement of parts. (Three-dimensional knitting) and breath air (net-like elastic body) were fixed with two strings.

Until now, there was no objective standard for pillow size, so the pillow size was quantified and a new standard was established.
By setting and quantifying the pillow size based on the height of the arch and the length of the external occipital protuberance to the length of the cervical vertebra (1st to 7th cervical vertebrae), we can provide the optimal pillow for medical customers Become.

The correct way to put the pillow is in the supine position, with the back of the head on the pillow and the eyes looking at the ceiling, the chin rising and not pressing the throat,
The pillow height is on the back, and the height of the cervical arc (cervical arch) is determined based on the height of the occipital bone from the bed.
The average height of the cervical arc (cervical arch) in the supine position is 3 cm for women and 4 cm for men.
As the height of the occipital bone increases, the cervical arc (cervical arch) also becomes higher than the average value.
The depth of the pillow is determined by the length from the extraoccipital occipital protuberance to the cervical vertebra (the first cervical vertebra to the seventh cervical vertebra).
Looking at the height of the cervical vertebra arc (cervical arch), which is the standard for pillow size, the average value of cervical vertebra arc (cervical arch) is 3cm for women, and the size is determined in 5mm increments. (Lower), M: 3 cm (normal), L: 3.5 cm (slightly higher), LL: 4 cm (higher), 3L: 4.5 cm (the back of the cat).
Cervical arch (cervical arch)-occipital bone height = pillow size in a supine position on the bed (futon).
In addition, the shape and length of the occipital bone and cervical vertebrae are determined by anatomical gender, so they can be made on a semi-order basis.

Further, the diameter of the cylindrical elastic body is set to S: 3 cm · M: 3.5 cm · L: 4 cm · LL: 4.5 cm · 3 L: 5. The best pillow height can be matched to anyone by setting it to cm.

As the size increases from S to M, the length from the occipital bone to the cervical vertebra increases, and the width of the pillow increases every 1 cm.

Medically, in rheumatoid arthritis, there is atlantoaxial instability due to the relaxation of the ligamentum of the atlantoaxial joint (cervical anteflexion and the anterior arch moves forward and downward with respect to the dentate process), but this cervical spine correction When the pillow is used, the anterior vertebral arch can be corrected backward with respect to the dental process, which is effective in preventing atlantoaxial instability in rheumatic patients.

In addition, the cervical vertebra is inclined toward the affected side in the case of hemiplegia resulting from cerebrovascular disorder, but the head is moved to the center by placing the occipital region in the occipital support part in the cross section of the central lower part of the truncated hemispherical hole. The effect of squeezing works, and the balance of the head on the cervical vertebra in the sagittal plane is improved, so that the torticollis is corrected and also effective in preventing torticollis.

In addition, because the head is located in the front and the cervical vertebra is located in the posterior part of the skeletal structure, the center of gravity of the head is located in the turret and the fulcrum is located in the occipital condyle of the occipital bone. The head (the occipital condyle of the occipital bone is posterior) and the cervical vertebra (annular joint) falls anteriorly and downwardly (nodding motion), causing a straight neck, contributing to neck pain, stiff shoulders, insomnia, and stress. However, by using the cervical spine correction pillow of the present invention, the physiological lordosis of the cervical spine is restored and returned to the original anatomical state, contributing to body health (homeostasis).

It is a perspective view which illustrates the inside of the cervical-vertebral correction pillow which shows the form for implementing this invention with a diagonal line. It is an external perspective view of the cervical vertebra correction pillow showing the form for carrying out the present invention.

One end of the viscoelastic shock absorber 34 a is in contact with the outer peripheral side surface of the cylindrical elastic body 21 and covers from the cervical vertebra lifting portion 2 to the cervical vertebra slope portion 3.

On the lower surface side of the viscoelastic shock absorber 34a, the above-described hollow vertical groove 31 is formed at the center thereof.
Viscoelastic shock absorbers 34b are provided on both sides of the hollow longitudinal groove 31. The viscoelastic shock absorber 34b is slightly harder than the viscoelastic shock absorber 34a on the upper surface side, and polyurethane is used as the material thereof. One end of the viscoelastic shock absorber 33b is in contact with the outer peripheral side surface of the cylindrical elastic body 21, and the other end side is wedge-shaped toward the head support portion 4 and gradually decreases in thickness at a constant linear rate. ing.

The hollow longitudinal groove 31 is formed by the inner side surfaces of the left and right viscoelastic shock absorbers 34b on the left and right inner side surfaces. The hollow vertical groove 31 is a so-called dovetail, and both the left and right inner surfaces are inclined upward toward the inner side of the groove, and the upper surface of the hollow vertical groove 31 is higher than the lower surface of the groove. It has become. The vertical groove 31 is closed on both the left and right sides with left and right viscoelastic shock absorbers 34b, the upper surface is closed with a viscoelastic shock absorber 34a, and the lower surface is closed with a stepped slope portion 33 described later. It is formed in a cavity.

On the lower surface side of the hollow longitudinal groove 31 and the left and right viscoelastic shock absorbers 34b, a stepped slope portion 33 is provided. The stepped slope portion 33 is made of an impact absorbing material.
Further, one end of the stepped slope portion 33 is in contact with the outer peripheral surface of the cylindrical elastic body 21, and the multi-end side is in contact with the upper surface of the stepped slope portion 33, which is thinned toward the head support portion 4 side. In addition, the stair-like slope part 33 is a foundation that supports the cervical arch of the cervical vertebra lifting part 2 and cervical slope part 3, and this step-like uneven structure absorbs the impact of the cervix when using a pillow, improving the fit and feeling of use. To do.

As described above, the cervical vertebra orthodontic pillow 1 has a cylindrical elastic body 21 having a hollow core portion, a pair of rubber tubes 22 provided on both sides of the hollow core portion, and a vertebra lifting cylindrical pad 27 placed sideways. Since the cavity 26 and the longitudinal groove 31 of the cavity are formed, the pressure of the spinous process of the cervical vertebra during use is relieved, and the gap between the cervical vertebra and the occipital region is eliminated, and the head does not escape without sitting in the cervical vertebra. Also good.
In addition, when used in the lateral position, the pressure on the ear is relieved and a soft fit is obtained.

  The left and right occipital side support portions 42 have breath air 42a formed so as to cover the spherical shape of the head, and the lower surface is similarly provided with a fusion 28b covering the hole 41a at the center, so that the occipital support The sitting of the cervical vertebra is also possible without the back of the head being escaped by the hole 41a of the portion 41.

The head support part 4 is provided with a fusion 28b in the upper part of a hole 41a of the occipital support part 41 formed at the center of the upper surface of the low resilience foam 24, and supports the occipital part.

The highly elastic sponge 23 surrounds all of the front side, the upper side, the rear side, and the bottom side of the cervical spine correction pillow 1. This cervical spine correction pillow 1 is covered with a cloth.

  The core part of the pillow uses a material with little stickiness, but when replacing the pillow material on the upper surface when the material deteriorates, the high elastic sponge 23 that covers the outer periphery of the pillow in an annular shape is removed and the brace fixed to the core part By removing the two strings of the air 42a and the fusions 28a and 28b, it is possible to easily replace the upper surface material of the pillow.

Further, simple adjustment of the pillow height is achieved by turning the high-elastic sponge 23 covering the outer periphery of the pillow in an annular shape to the center and taking out the vertebra lifting cylindrical pad 27 from the pocket 25 provided in the center of the circular elastic body 21. Size exchange was easy.

Next, a method of using the cervical spine correction pillow 1 based on the configuration of the embodiment for carrying out the above-described device will be described below.
According to the present invention, when the occipital region is placed on the occipital region support part and the user raises his / her chin, it is cylindrical with the cervical vertebrae to the third cervical vertebrae as fulcrums while maintaining the physiological lordosis of the cervical vertebrae. The elastic body holds the cervical vertebrae, and the weight of the head and cervix slowly lowers the cervix from the back of the head, and the lifting force acts on the cylindrical elastic body and the cervical vertebral slope to naturally extend the cervical vertebrae radially and arched Warping occurred and a physiological lordosis was formed, allowing the cervical curvature to return to its original state.
The occipital region was placed in the hole 41a of the occipital support portion 41, the lower edge of the occipital region was placed on the upper side of the cervical slope portion 3, and the rear surface side of the neck was placed on the upper side of the cylindrical elastic body 21 of the cervical vertebra lifting portion 2 of the cervical vertebra correction pillow 1.
In this manner, in the supine position, the cylindrical elastic body 21 holds the cervical vertebrae while the occipital region is placed in the hole 41a of the occipital support 41 and the jaws are slightly raised to hold the physiological lordosis of the cervical spine. The weight of the cervical part slowly lowers the cervical part from the back of the head, and the lifting force acts on the cylindrical elastic body 21 and the cervical vertebral slope part 3 so that the cervical vertebra is radiated and pulled in an arcuate manner, thereby arranging the cervical vertebrae. 2 and the cervical vertebral slope 3 are formed with a natural cervical vertebral forehead without difficulty, and the cervical curvature can be corrected and held while sleeping.
Further, the curvature of the lower cervical vertebra 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.
