Description

How to adjust spinal curve by changing sleeping position

The present invention relates to a method for adjusting spinal curves by changing sleeping positions, and in particular to a method for adjusting spinal curves by changing sleeping positions by simultaneously adjusting a pillow and a mattress so that the user's cervical vertebrae, thoracic vertebrae, lumbar vertebrae, coccyx, sacrum and pelvis return to a normal posture during sleep.

Modern people lead busy lives. Long-term poor posture can easily lead to symptoms such as poor posture and back pain. Therefore, physical therapists have begun to appear to help people with poor posture relieve symptoms. However, because posture is not easy to change in daily life, symptoms often recur over time after physical therapy.

Body posture can be divided into standing, sitting and sleeping positions. The sleeping position can be adjusted by customizing the mattress to help adjust the user's body position during sleep. Therefore, there are many sleeping pillows and sleeping mattresses on the market. However, everyone's body shape is different, and mass-produced standard products can only fit the human body shape but not necessarily the correct curve.

In addition, under the influence of modern people sitting for a long time, most people have the problem of lumbar spine and pelvis tilting forward or backward. In order to help the pelvis return to normal during sleep, the common adjustment method is to place objects under the knees to raise the knees, so that the pelvis tilts backward and the lumbar spine is pressed against the bed surface, reducing the pressure on the waist muscles. However, it will also exert a backward squeezing force on the intervertebral disc, which is easy to cause intervertebral disc damage in the long run. In addition, it is common to know that most mattresses are designed to fit the body shape, but the lumbar spine sinking and fitting against the mattress does not mean that it is well supported.

In view of this, the inventor of the present invention has devoted himself to research and design, hoping to provide a method for adjusting the spinal curve by changing the sleeping position, which can allow the user to adjust the cervical vertebrae, thoracic vertebrae, lumbar vertebrae, coccyx, sacrum and pelvis to restore to a normal posture during sleep. This is the motivation for the invention.

The main purpose of the present invention is to provide a method for adjusting the spinal curve by changing the sleeping position, which can customize the pillow and the mattress together and take into account both supine and side sleeping positions.

By customizing the different softness and hardness of the mattress and various pads, the invention can keep the cervical vertebrae, thoracic vertebrae, lumbar vertebrae, coccyx, sacrum and pelvis in a normal human posture, achieving the effect of adjusting the body posture during sleep.

The present invention includes a supine cervical spine measurement step, a supine thoracic spine measurement step, a side-sleeping thoracic spine measurement step, and a lumbar spine measurement step. It may further include a side-sleeping cervical spine measurement step, a supine pelvic measurement step, and a side-sleeping pelvic measurement step to further fine-tune the user's posture when sleeping on his back or on his side.

The supine cervical spine measurement step is to let a user lie on his back on the central supine area of a pillow, the central supine area has a central headrest area corresponding to the user's head and a central neckrest area corresponding to the user's neck, and at least one head supine pad is used to adjust the height of the central headrest area to an angle of 10 degrees between the line connecting the user's eye corner and ear hole and the vertical line, and at least one neck supine pad is used to adjust the height of the central neckrest area to an angle of 18 degrees between the user's sternocleidomastoid muscle and the horizontal line. The cervical spine is allowed to maintain a normal curve when sleeping on the back, helping to correct the symptoms of cervical hyperstraightness or turtle neck.

The side sleeping cervical vertebra measurement step is to let the user lie on the side sleeping area on the left and right sides of the pillow. Each side sleeping area has a side sleeping head pillow area corresponding to the user's head and a side sleeping neck pillow area corresponding to the user's neck. At least one head side sleeping pad is used to adjust the height of the side sleeping head pillow area to the level of the user's head, and at least one neck side sleeping pad is used to adjust the height of the side sleeping neck pillow area to the level of the connection line between the second to seventh cervical vertebrae of the user. That is, when viewed from the front, the center point of the user's eyes and the connection line are horizontal, and when viewed from the back, the connection line between the second to seventh cervical vertebrae of the user is horizontal.

The supine thoracic spine measurement step allows the user to lie supinely on a mattress, the mattress comprising a support layer, a balancing layer above the support layer, and a comfort layer above the balancing layer, the mattress having a central thoracic spine area corresponding to the thoracic vertebrae of the user when lying supinely, and measuring the height difference between the thoracic vertebrae of the user and the horizontal line when the user lies supinely, and adjusting the hardness of the balancing layer in the central thoracic spine area according to the height difference until the thoracic vertebrae of the user are horizontal when lying supinely.

If the user has a hunchback that causes the thoracic vertebrae to tilt backward (i.e., the upper back and head of the user cannot touch the wall when standing against the wall, and a higher pillow is needed), a thoracic support pad can be removably placed between the balance layer and the comfort layer at the position where the user's thoracic vertebrae tilt backward during the supine thoracic measurement step. The thoracic support pad can support the user's tilted thoracic vertebrae and correct the thoracic vertebrae back to their normal position.

The side-sleeping thoracic spine measurement step allows the user to lie sideways on the side-lying areas on the left and right sides of the mattress. Each side-lying area has a side-lying thoracic spine area corresponding to the thoracic vertebrae of the user when lying sideways. The height difference between the thoracic vertebrae of the user and the horizontal line is measured when the user lies sideways. The hardness of the balancing layer in each side-lying thoracic spine area is adjusted according to the height difference until the thoracic vertebrae of the user are horizontal when lying sideways.

The lumbar measurement step is to let the user lie on his back on the mattress, and at least one lumbar pad is removably placed between the balance layer and the comfort layer at the position corresponding to the user's lumbar vertebrae to actively support the user's lumbar vertebrae. The height of the lumbar pad can be more than 0.5 cm, and the height of the lumbar pad can be adjusted according to the depth of the vertebral arch of the individual's waist. Users with deeper vertebral arches can choose thicker lumbar pads.

The supine pelvic measurement step is to let the user lie on the mattress on his back, and removably insert at least one pelvic adjustment pad between the balance layer and the comfort layer at the thigh position in front of the user's knees or below the knees, so that the user's lumbar vertebrae and pelvis are level. The height of the pelvic adjustment pad can be more than 1 cm, and the height of the pelvic adjustment pad increases with the height of the lumbar pad. The pelvic adjustment pad can be adjusted according to whether the user's pelvis is tilted forward or backward. If the pelvis is tilted forward, the pelvic adjustment pad is placed at the thigh position in front of the user's knees; if the pelvis is tilted backward, the pelvic adjustment pad is placed below the user's knees. The present invention uses a lumbar pad in combination with a pelvic adjustment pad. When the pelvic adjustment pad pushes the user's pelvis back to the correct position, the lumbar pad actively supports the user's lumbar vertebrae. This avoids the use of a pelvic adjustment pad alone in the conventional method, which causes the lumbar vertebrae to be subjected to additional burden or even damages the intervertebral disc.

The side-sleeping pelvic measurement step allows the user to lie sideways on the side-lying areas on the left and right sides of the mattress. Each side-lying area has a side-lying pelvic area corresponding to the pelvic part of the user when lying sideways. The height difference between the coccyx, sacrum and pelvis of the user and the horizontal line is measured when the user lies sideways. The softness and hardness of the balancing layer in each side-lying pelvic area is adjusted according to the height difference until the coccyx, sacrum and pelvis of the user are level when lying sideways.

The invention measures the data of the pillow and mattress when the user lies on his back or side, and can customize a pillow according to the height data of the central headrest area, central neckrest area, each side-sleeping headrest area, and each side-sleeping neckrest area of the pillow; or customize a mattress with different softness and hardness distribution according to the hardness data of the central thoracic area, each side-lying thoracic area, and each side-lying pelvic area. Whether the user is used to sleeping on his back or side, he can correct his body posture during sleep, and the cervical vertebrae, thoracic vertebrae, coccyx, sacrum, and pelvis can be assisted to return to the normal body position during sleep.

In order to further understand the features, characteristics and technical contents of the present invention, please refer to the following detailed description of the present invention.

Please refer to the first figure, which discloses the illustration of the implementation method of the present invention. The above figure illustrates the method of adjusting the spinal curve by changing the sleeping position, which includes a supine cervical spine measurement step S1, a supine thoracic spine measurement step S3, a side-sleeping thoracic spine measurement step S4 and a lumbar spine measurement step S5; this embodiment further includes a side-sleeping cervical spine measurement step S2, a supine pelvic measurement step S6 and a side-sleeping pelvic measurement step S7, which are used to fine-tune the user's posture when sleeping on his back and on his side, and help the user return to a normal posture.

As can be seen in the second figure, the supine sleeping cervical spine measurement step S1 of the present invention allows a user to lie on his back on the central supine area 11 of a pillow 1, and the central supine area 11 has a central headrest area 111 corresponding to the user's head and a central neckrest area 112 corresponding to the user's neck. The height of the central headrest area 111 is adjusted to an angle of 10 degrees between a line connecting the user's eye corners and ear holes (i.e., an eye corner-ear hole connecting line A) and a vertical line V by at least one head supine pad 1111, and the height of the central neckrest area 112 is adjusted to an angle of 18 degrees between the user's sternocleidomastoid muscle B and a horizontal line H by at least one neck supine pad 1121. When the angle between the line connecting the user's eye corner and ear hole and the vertical line V is 10 degrees, the user's cervical vertebrae 2 to 4 can maintain a normal posture; when the angle between the user's sternocleidomastoid muscle B and the horizontal line H is 18 degrees, the user's cervical vertebrae 5 to 7 can maintain a normal posture. Therefore, when the user lies on his back on the pillow 1, the second to seventh cervical vertebrae C maintain a normal posture and a normal curve, which helps correct the symptoms of cervical hyperstraightness or turtle neck.

As can be seen in the third figure, the side-sleeping cervical vertebrae measurement step S2 of the present invention allows the user to lie sideways on the side sleeping areas 12 on the left and right sides of the pillow 1, and each side sleeping area 12 has a side sleeping headrest area 121 corresponding to the user's head and a side sleeping neck pillow area 122 corresponding to the user's neck. The height of the side sleeping headrest area 121 is adjusted to the level of the user's head by at least one head side sleeping pad 1211, and the height of the side sleeping neck pillow area 122 is adjusted to the level of the connection line of the second to seventh sections of the user's cervical vertebrae C by at least one neck side sleeping pad 1221, that is, the center point of the user's eyes and the connection line are level when viewed from the front, and the connection line of the second to seventh sections of the user's cervical vertebrae C is level when viewed from the back. Therefore, the present invention can ensure that the cervical vertebrae C of the user remains horizontal when the user sleeps on his side.

As can be seen in the fourth figure, the present invention can measure the height data of the central headrest area 111, the central neckrest area 112, each side sleeping headrest area 121 and each side sleeping neckrest area 122 of the pillow 1, and then customize a pillow 1 according to each height data to help the user's neck restore its normal curve and posture.

As can be seen in the fifth figure, the supine thoracic spine measurement step S3 of the present invention allows the user to lie on his back on a mattress 2, which includes a support layer 21, a balance layer 22 above the support layer 21, and a comfort layer 23 above the balance layer 22. The support layer 21 can be made of foam, latex or springs of sufficient hardness, the balance layer 22 can be made of elastic material, and the comfort layer 23 can be made of soft material. The mattress 2 is made of a soft material such as wool, horse hair, synthetic fiber or foam, and has a central thoracic region 24 corresponding to the thoracic vertebra D of the user when lying on his back. The height difference between the thoracic vertebra D and the horizontal line H is measured when the user lies on his back, and the hardness of the balancing layer 22 in the central thoracic region 24 is adjusted according to the height difference until the thoracic vertebra D of the user is horizontal when lying on his back.

If the thoracic vertebrae D of the user is upward and above the horizontal line when the user lies on his back, it means that the mattress 2 is too hard. The hardness of the balancing layer 22 in the central thoracic region 24 can be adjusted to be softer so that the thoracic vertebrae D of the user can be moved downward to the horizontal line H. Conversely, if the thoracic vertebrae D of the user is downward and below the horizontal line when the user lies on his back, it means that the mattress 2 is too soft. The hardness of the balancing layer 22 in the central thoracic region 24 can be adjusted to be harder so that the thoracic vertebrae D of the user can be moved upward to the horizontal line H.

If the user has a hunchback phenomenon that causes the thoracic vertebrae to tilt backward (i.e., the upper back and head of the user cannot be attached to the wall when standing against the wall, and a higher pillow is required), a thoracic vertebra support pad 28 can be removably placed between the balance layer 22 and the comfort layer 23 corresponding to the user's thoracic vertebrae tilt backward in the supine thoracic vertebra measurement step S3. The thoracic vertebra support pad 28 can assist in supporting the user's tilted thoracic vertebrae D, so that the thoracic vertebrae D can be corrected back to the normal position. For example, the size of the thoracic vertebra support pad 28 can be 12x75x1 cm (length x width x height), and the shape and height can be adjusted according to the actual body shape of the user.

As can be seen in the sixth figure, the side-sleeping thoracic spine measurement step S4 of the present invention allows the user to lie sideways in the side-lying areas 25 on the left and right sides of the mattress 2. Each side-lying area 25 has a side-lying thoracic spine area 251 corresponding to the thoracic vertebra D portion of the user when lying sideways, and measures the height difference between the thoracic vertebra D portion of the user and the horizontal line H when the user lies sideways. The softness and hardness of the balancing layer 22 in each side-lying thoracic spine area 251 is adjusted according to the height difference until the thoracic vertebra D of the user is horizontal when lying sideways.

If the thoracic vertebrae D of the user is upward and higher than the horizontal line when the user lies on his side, it means that the mattress 2 is too hard. The hardness of the balancing layer 22 in the side-lying thoracic vertebrae area 251 can be adjusted to be softer so that the thoracic vertebrae D of the user can be moved downward to the horizontal line H. Conversely, if the thoracic vertebrae D of the user is downward and lower than the horizontal line when the user lies on his side, it means that the mattress 2 is too soft. The hardness of the balancing layer 22 in the side-lying thoracic vertebrae area 251 can be adjusted to be harder so that the thoracic vertebrae D of the user can be moved upward to the horizontal line H.

When the user sleeps on his side, the middle part of the chest cavity of the user's body is concentrated on the shoulders, which may cause compression of the shoulders and cause tightness and soreness in the shoulders. Therefore, if the side-lying thoracic vertebrae area 251 is made softer than the central thoracic vertebrae area 24, the side-lying thoracic vertebrae area 251 can accommodate the user's shoulders and the user's shoulders will not be compressed.

As can be seen in FIG. 7, the lumbar measurement step S5 of the present invention allows the user to lie on his back on the mattress 2, and at least one lumbar pad 26 is removably inserted between the balance layer 22 and the comfort layer 23 at the position corresponding to the user's lumbar vertebra E, actively supporting the user's lumbar vertebra E. The height of the lumbar pad 26 can be more than 0.5 cm, and the height of the lumbar pad 26 can be adjusted according to the depth of the vertebral arch of the individual's waist. Users with deeper vertebral arches can choose thicker lumbar pads 26.

As shown in FIG. 7 , the supine pelvic measurement step S6 of the present invention allows the user to lie on the mattress and removably insert at least one pelvic adjustment pad 27 between the balance layer 22 and the comfort layer 23 at the position of the thigh I in front of the user's knee or below the knee G, so that the user's lumbar vertebra E and pelvis F are level. The height of the pelvic adjustment pad 27 can be more than 1 cm, and the height of the pelvic adjustment pad 27 increases as the height of the lumbar pad 26 increases. Please note that for the sake of convenience in explanation, two pelvic adjustment pads 27 are drawn in FIG. 7, but in fact, the pelvic adjustment pads 27 can be adjusted according to whether the user's pelvis F is tilted forward or backward. If the pelvis F is tilted forward, the pelvic adjustment pad 27 is placed at the thigh I position in front of the user's knee G to push the pelvis F backward; if the pelvis F is tilted backward, the pelvic adjustment pad 27 is placed under the user's knee G to push the pelvis F forward, so usually only one pelvic adjustment pad 27 is needed. If the user's pelvis F does not tilt forward or backward, the pelvic adjustment pad 27 is not needed, and only the lumbar pad 26 is needed to actively support the lumbar vertebrae E.

The present invention uses a lumbar pad 26 in combination with a pelvic adjustment pad 27. When the pelvic adjustment pad 27 pushes the user's pelvis F back to the correct position, the lumbar pad 26 actively supports the user's lumbar vertebrae E, so that the lumbar vertebrae E will not be subjected to additional burden or damage the intervertebral disc as in the conventional method of using the pelvic adjustment pad 27 alone. The shape and height of the lumbar pad 26 and the pelvic adjustment pad 27 can be adjusted according to the forward tilt of the user's pelvis F.

To measure whether the user's pelvis F is tilted, the user can stand against a wall and observe the distance between the top of the user's pelvis F and the wall. In a normal posture, the distance between the pelvis F and the wall can roughly accommodate the user's hand from the side to the palm position. If the user's hand can only be inserted to the position of the fingers or cannot be inserted above the pelvis F (that is, the distance is relatively small), it means that the user is tilted. If the user's pelvis F is tilted backward, a pelvis adjustment pad 27 needs to be placed below the knee G to help the pelvis F return to its original position. If the distance between the pelvis F and the wall is large (e.g., it can accommodate the user's fist), it means that the user's pelvis F is tilted forward. In this case, a pelvis adjustment pad 27 needs to be placed at the thigh I position in front of the knee G to help the pelvis F return to its original position.

In the present invention, the height of the lumbar pad is more than 0.5 cm, and the height of the pelvic adjustment pad is more than 1 cm. The height of the pelvic adjustment pad 27 increases with the height of the lumbar pad 26. For example, a user whose pelvis F does not tilt forward can use a 0.5 cm high lumbar pad 26 to actively support the lumbar vertebrae. If the user's pelvis F tilts forward slightly, a 1 cm high lumbar pad 26 and a 1 cm high pelvic adjustment pad 27 can be used; if the user's pelvis F tilts forward more severely, a 1.5 cm high lumbar pad 26 and a 2 cm high pelvic adjustment pad 27 can be used. The height of the pelvic adjustment pad 27 is roughly two to three times the height of the lumbar pad 26 minus 0.5 cm.

The side-sleeping pelvic measurement step S7, as can be seen in the sixth figure, allows the user to lie sideways on the side-lying areas 25 on the left and right sides of the mattress 2. Each side-lying area 25 has a side-lying pelvic area 252 corresponding to the pelvic F portion of the user when lying sideways. The height difference between the coccyx (not shown), sacrum (not shown) and pelvic F portion of the user and the horizontal line H is measured when the user lies sideways. The softness and hardness of the balancing layer 22 in each side-lying pelvic area 252 is adjusted according to the height difference until the coccyx (not shown), sacrum (not shown) and pelvis F of the user are level when lying sideways.

As can be seen in FIG. 8 , the present invention can use the hardness data of the central thoracic spine area 24, each side-lying thoracic spine area 251 and each side-lying pelvic spine area 252 to customize a mattress 2, the mattress 2 includes a support layer 21, a balancing layer 22 above the support layer 21 and a comfort layer 23 above the balancing layer 22, and a lumbar pad 26 and a pelvic adjustment pad 27 can be placed between the balancing layer 22 and the comfort layer 23 according to the user's pelvic forward tilt condition. Since the lumbar pad 26 and the pelvic adjustment pad 27 only work when the user lies on his back, the width of the lumbar pad 26 and the pelvic adjustment pad 27 is smaller than the mattress 2, so that the user will not be affected by the lumbar pad 26 and the pelvic adjustment pad 27 when sleeping on his side. If the user has a hunchback, a thoracic support pad 28 can be removably placed between the balance layer 22 and the comfort layer 23. The thoracic support pad 28 can assist in supporting the user's backward-leaning thoracic vertebra D, so that the thoracic vertebra is corrected back to a normal body position. The size of the thoracic support pad 28 can be 12x75x1 cm (length x width x height).

The present invention can help users who are used to sleeping on their backs or sides to correct their body posture during sleep. The cervical vertebrae C, thoracic vertebrae D, coccyx (not shown), sacral vertebrae (not shown) and pelvis F can all be assisted to return to normal body positions during sleep. Users can choose which measurement steps of the present invention to implement according to their personal body needs and sleeping habits, such as only implementing the measurement steps related to lying on your back, or also implementing the steps related to sleeping on your side.

However, the above is only a preferred embodiment of the present invention and should not be used to limit the scope of the present invention. Any changes and modifications that are obviously possible for people skilled in the art should be considered as not deviating from the essential content of the present invention.
