Description

Technical Field

[0001] The invention belongs to the technical field of pillows, in particular to a multifunctional cervical spondylosis prevention and treatment pillow. Background Art

[0002] Cervical spondylosis is a common disease that affects the functions of multiple systems of the human body and presents various clinical symptoms. Studies have found that the root cause of cervical spondylosis is closely related to the structure of the pillow.

[0003] Pillows are an indispensable item in daily life, and their design has an important impact on human health. A properly designed pillow can provide good support and adjustment, help improve sleep quality, and reduce cervical problems caused by improper sleeping posture. Especially for patients with cervical spondylosis, a properly constructed and suitable pillow can not only relieve cervical pain and discomfort, but also solve the root cause of cervical spondylosis and help recover from the disease.

[0004] Traditional pillows usually have only one plane with the same height, while the human body requires five heights and eight supporting surfaces. The key problem is that the human body has shoulder support when lying on the side, but no shoulder support when lying on the back. Therefore, the relative height difference between lying on the side and lying on the back is large. Therefore, a pillow with only one height and one supporting surface cannot meet the requirements of five heights and eight supporting surfaces required by the human body. The structure of traditional pillows not only destroys the normal physiological curvature of the human body, but also destroys the normal biomechanical balance of the cervical spine. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a multifunctional cervical spondylosis prevention and treatment pillow, which solves the problem that the structure of the traditional pillow destroys both the normal physiological curvature of the human body and the normal biomechanical balance of the cervical spine.

[0006] The technical solution of this application is: A multifunctional cervical spondylosis prevention and treatment pillow comprises a pillow body provided with a supine back head support portion, a side-lying face support portion, and a supine cervical vertebra support portion, the side-lying face support portion is respectively provided with a side-lying ear acupoint support portion and a side-lying cervical vertebra support portion, the side-lying ear acupoint support portion has a lower height than the side-lying face support portion, the side-lying cervical vertebra support portion has a higher height than the side-lying face support portion, the supine cervical vertebra support portion comprises a first supine cervical vertebra support surface and a second supine cervical vertebra support surface, the first supine cervical vertebra support surface has a lower height than the side-lying face support portion, and the second supine cervical vertebra support surface has a higher height than the side-lying face support portion. The present invention has high sides and a low middle part, and the low middle part is specially used for the neck when lying on the back. The principle is that according to the height of the physiological curvature of the human cervical spine, when the user lies on his back, the present invention matches the normal height of the cervical spine curvature, plays a protective role in maintaining the cervical spine curvature from being damaged, and keeps the head and neck in a balanced state. The high sides are specially used when the user lies on the left or right side, and plays a role in fixing and braking the head and neck to prevent abnormal movements of the head and neck.

[0007] Furthermore, the side-lying ear acupoint supporting portion includes a first side-lying ear acupoint supporting surface and a second side-lying ear acupoint supporting surface which are symmetrically arranged with respect to the supine back of the head supporting portion, and the heights of the first side-lying ear acupoint supporting surface and the second side-lying ear acupoint supporting surface are both lower than the height of the side-lying face supporting portion.

[0008] Furthermore, the first side-lying ear acupoint supporting surface and the second side-lying ear acupoint supporting surface are rectangular, which can more easily adapt to different ear shapes and sizes, ensure that the supporting surface fits the ear well, and the rectangular shape can support the ear more evenly, avoid excessive local pressure, and improve comfort.

[0009] Furthermore, the side-lying cervical vertebra supporting portion includes a first side-lying cervical vertebra supporting surface and a second side-lying cervical vertebra supporting surface symmetrically arranged with respect to the supine back of the head supporting portion, and the first side-lying cervical vertebra supporting surface and the second side-lying cervical vertebra supporting surface are arranged along the long side of the pillow body.

[0010] Furthermore, the first side-lying ear point supporting surface is arranged above the first side-lying cervical vertebra supporting surface, and the second side-lying ear point supporting surface is arranged above the second side-lying cervical vertebra supporting surface. This design better fits the natural curve of the human head and neck, provides more scientific support, improves comfort, and can better adapt to the side-lying sleeping position, ensuring that the ears and neck are effectively supported at the same time, thereby improving sleep quality.

[0011] Furthermore, the dimensions of the first side-lying ear point supporting surface and the second side-lying ear point supporting surface along the width direction of the pillow body are 80 mm, and the dimensions of the first side-lying cervical vertebra supporting surface and the second side-lying cervical vertebra supporting surface along the width direction of the pillow body are 70 mm.

[0012] Furthermore, arc-shaped transition surfaces are provided between the first supine cervical vertebra supporting surface and the first side-lying cervical vertebra supporting surface and the second side-lying cervical vertebra supporting surface on both sides. The arc-shaped transition surfaces can reduce the pressure of sharp edges on the neck, provide more natural support, and improve the comfort of use; they help to evenly disperse the pressure on the neck, avoid excessive local pressure, and reduce discomfort.

[0013] Furthermore, the height of the side-lying facial support portion is 90 mm, the height of the bottom of the side-lying ear acupoint support portion is 75 mm, the depth of the side-lying ear acupoint support portion is 15 mm, the height of the side-lying cervical support portion is 105 mm, the height of the first supine cervical support surface is 40 mm, and the height of the second supine cervical support surface is 110 mm.

[0014] Furthermore, the pillow body is made of space memory foam, which is both soft and supportive, and has greater advantages than other materials.

[0015] Furthermore, the total length of the pillow body is 660 mm and the total width is 320 mm.

[0016] The specific beneficial effects of the present invention include: 1. The present invention has high sides and low middle, and the low middle part is specially used for the neck when lying on its back. The principle is that according to the height of the physiological curvature of the human cervical spine, when the user lies on his back, the present invention matches the normal height of the cervical spine curvature, plays a protective role in maintaining the cervical spine curvature from being damaged, and keeps the head and neck in a balanced state. The high sides are specially used when the user lies on the left or right side, and play a role in fixing and braking the head and neck to prevent abnormal movement of the head and neck; 2. The present invention uses the same supporting surface for cervical ankylosing and cervical hyperextension, and is specially used for patients with cervical ankylosing or cervical hyperextension. The ankylosing or hyperextension cervical vertebra can be naturally and infinitely pulled on the supporting surface of the pillow body and corrected to the physiological curvature of a normal person; 3. The height of the ear point support part when lying on the side is lower than that of the face support part when lying on the side, so that the ears are free from the heavy pressure of the head, thus achieving a comfortable effect; 4. The present invention matches the curvature of various parts of the human body through six heights and nine supporting surfaces, so that the head, neck, shoulders and back form a perfect combination of parallel and balanced states on the pillow body and the bed body, ensuring the stability of the human cervical spine balance.

[0024] A multifunctional cervical spondylosis prevention and treatment pillow comprises a pillow body provided with a supine back of the head support portion 1, a side-lying face support portion 2, and a supine cervical vertebra support portion 3, the side-lying face support portion 2 is respectively provided with a side-lying ear point support portion 4 and a side-lying cervical vertebra support portion 5, the side-lying ear point support portion 4 has a lower height than the side-lying face support portion 2, the side-lying cervical vertebra support portion 5 has a higher height than the side-lying face support portion 2, the supine cervical vertebra support portion 3 comprises a first supine cervical vertebra support surface 31 and a second supine cervical vertebra support surface 32, the first supine cervical vertebra support surface 31 has a lower height than the side-lying face support portion 2, and the second supine cervical vertebra support surface 32 has a higher height than the side-lying face support portion 2.

[0025] The present invention is designed according to the physiological characteristics of the human body. When lying on the side, there are shoulders on both sides for support, and when lying on the back, there is no shoulder on the back. Therefore, the relative height difference between lying on the side and lying on the back is relatively large. Therefore, the same pillow body is designed to meet the sleeping posture requirements of two different heights, one with shoulders and the other without shoulders. The shape of the pillow is a U-shaped pillow with a low middle and high ends.

[0026] On the basis of the above-mentioned embodiment, as a preferred embodiment, the side-lying ear point supporting portion 4 includes a first side-lying ear point supporting surface 41 and a second side-lying ear point supporting surface 42 which are symmetrically arranged with respect to the supine back of the head supporting portion 1, and the heights of the first side-lying ear point supporting surface 41 and the second side-lying ear point supporting surface 42 are both lower than the height of the side-lying face supporting portion 2.

[0027] Specifically, the side-lying face supporting portion 2 includes a first side-lying face supporting surface 21 and a second side-lying face supporting surface 22 , and the first side-lying face supporting surface 21 and the second side-lying face supporting surface 22 are symmetrically arranged with respect to the supine back of the head supporting portion 1 .

[0028] Based on the above embodiment, as a preferred embodiment, the first side-lying ear acupoint supporting surface 41 and the second side-lying ear acupoint supporting surface 42 are rectangular. When lying on one's side, the ears are placed on the first side-lying ear acupoint supporting surface 41 and the second side-lying ear acupoint supporting surface 42 to avoid the heavy pressure on the head, thereby achieving a comfortable effect.

[0029] On the basis of the above-mentioned embodiment, as a preferred embodiment, the side-lying cervical vertebra supporting portion 5 includes a first side-lying cervical vertebra supporting surface 51 and a second side-lying cervical vertebra supporting surface 52 which are symmetrically arranged with respect to the supine back of the head supporting portion 1, and the first side-lying cervical vertebra supporting surface 51 and the second side-lying cervical vertebra supporting surface 52 are arranged along the long side of the pillow body.

[0030] Based on the above embodiment, as a preferred embodiment, the first side-lying ear point supporting surface 41 is arranged above the first side-lying cervical vertebra supporting surface 51, and the second side-lying ear point supporting surface 42 is arranged above the second side-lying cervical vertebra supporting surface 52.

[0031] Based on the above embodiment, as a preferred embodiment, the dimensions of the first side-lying ear point supporting surface 41 and the second side-lying ear point supporting surface 42 along the width direction of the pillow body are 80 mm, and the dimensions of the first side-lying cervical vertebra supporting surface 51 and the second side-lying cervical vertebra supporting surface 52 along the width direction of the pillow body are 70 mm.

[0032] On the basis of the above-mentioned embodiment, as a preferred embodiment, arc-shaped transition surfaces are provided between the first supine cervical vertebra supporting surface 31 and the first lateral cervical vertebra supporting surface 51 and the second lateral cervical vertebra supporting surface 52 on both sides.

[0033] Based on the above embodiment, as a preferred embodiment, the height of the side-lying face supporting part 2 is 90 mm. Figure 3 The height of the bottom of the side-lying ear acupuncture support portion 4 is 75mm, such as Figure 3 The depth of the side-lying ear point supporting portion 4 is 15mm, such as Figure 3 The height of the side-lying cervical vertebra supporting portion 5 is 105mm, such as Figure 3 h1 marked in; the height of the first supine cervical vertebra supporting surface 31 is 40mm, and the height of the second supine cervical vertebra supporting surface 32 is 110mm, such as Figure 3 h4 marked in the figure.

[0034] Based on the above implementation, as a preferred implementation, the pillow body is made of space memory foam, which has both softness and support, and is more superior than other materials.

[0035] Based on the above implementation, as a preferred implementation, the total length of the pillow body is 660 mm and the total width is 320 mm.

[0036] Specifically, the middle low part of the present invention is designed to be used for supine lying of the neck. The principle is that according to the height of the physiological curvature of the human cervical spine, there is only a limit error of 12 mm ± 5 mm, that is, the maximum cannot be higher than 17 mm and the minimum cannot be lower than 7 mm. The height of the middle low part of the pillow is designed to match the normal height of the cervical spine curvature, thereby playing a protective role in maintaining the cervical spine curvature from being damaged.

[0037] Specifically, the depth of the back of the head supporting portion 1 for lying supine is designed to be lower than the height of the first supine cervical vertebra supporting surface 31 because the diameter of the back of the head is larger than the diameter of the cervical vertebra (neck). Therefore, the depth of the back of the head supporting portion 1 for lying supine should be lower than the height of the first supine cervical vertebra supporting surface 31. In this way, the depth of the back of the human head can match that of the back of the head supporting portion 1 for lying supine and the height after implementation is almost zero, which plays a role in keeping the head and neck in a balanced state. The raised parts at the left and right ends, namely the first side-lying facial supporting surface 21, the second side-lying facial supporting surface 22, the first side-lying cervical vertebra supporting surface 51, and the second side-lying cervical vertebra supporting surface 52, are designed for use by people lying on their left and right sides, and play a role in fixing and braking the head and neck to prevent abnormal movements of the head and neck.

[0038] Specifically, another supporting surface, namely, the second supine cervical vertebra supporting surface 32, is designed for patients with cervical vertebra ankylosing or cervical vertebra hypertension. The ankylosing or hypertensioned cervical vertebra can be naturally and infinitely pulled on the pillow supporting surface and corrected to the physiological curvature of a normal person. The height of the face is designed to be lower than the neck, which is specially used for the left and right side-lying cervical vertebra supporting surfaces and the left and right face supporting surfaces. Because the diameter of the human face is larger than the diameter of the neck, the height of the face should be lower than the actual height of the neck.

[0039] Specifically, the ear acupoint support part for lying on the side of the ear is designed to be lower than the height of the face support part for lying on the side of the ear, so that the force on the support surfaces of the two is equal, so that the ear is free from the heavy pressure of the head, thereby achieving a comfortable effect. In accordance with the different physical structures of various parts of the human body, the pillow structure is generally established to have five heights and eight support surfaces, while those with ankylosing and hypertonicity have one more height and one support surface, which makes it six heights and nine support surfaces. These structures are matched with the curved structures of various parts of the human body, so that the head, neck, shoulders, and back form a perfect combination of a parallel and balanced state on the pillow body and the bed body, ensuring the stability of the human cervical spine balance. In short, different types of cervical spondylosis suffered by humans can be cured and rehabilitated on the same multifunctional cervical spondylosis prevention and treatment pillow.

[0040] The present invention is a unique product for preventing and treating cervical spondylosis from the root. It is a new thing and new discovery that has never been seen since ancient times and treats cervical spondylosis without drugs or any other methods. It is a scientific and healthy new product with high theory and high efficiency. This product uses the "yin and yang balance" theory of traditional Chinese medicine and the "mechanical therapy" of biotechnology. During use, the biomechanical effect of the pillow on the human body is naturally adjusted to a perfect combination system in which the human head, neck, shoulders, back and torso are in a parallel state on the pillow and the bed. Because the pillow forces the cervical vertebra to be in a natural balanced state, the surrounding tissues of the cervical vertebra and the physiological curvature of the cervical vertebra will not be damaged or destroyed. Therefore, different types of cervical spondylosis can be prevented and treated unconsciously during sleep.

[0041] The method of use of the present invention is as follows: 1. When the patient is a member of the general public without cervical ankylosis or cervical hyperextension: When lying on the back, the patient's head is located in the supine back head support part 1, and the neck is located on the first supine cervical vertebra support surface 31; When lying on the left side, the patient's face is located on the first face supporting surface 21, the ear is located in the first side-lying ear point supporting surface 41, and the neck is located on the first side-lying cervical vertebra supporting surface 51; When lying on the right side, the patient's face is located on the second face supporting surface 22, the ear is located in the second side-lying ear point supporting surface 42, and the neck is located on the second side-lying cervical vertebra supporting surface 52; 2. When the patient has cervical ankylosis or cervical hyperextension: When lying on the back, the patient's neck is located on the second supine cervical vertebra supporting surface 32, and the head is suspended in the back head supporting surface 1 for traction.
