Description

[0001] This application is a divisional application of the following application. The application date of the original application is April 27, 2020, the application number of the original application is 2020103460036, and the invention name of the original application is: A spinal traction pillow and its pillow core. Technical Field

[0002] The invention relates to the field of medical equipment, and in particular to a spinal traction pillow and a pillow core thereof. Background Art

[0003] Nowadays, people spend more and more time sitting at desks and in car seats, and the incidence of spinal diseases in the population is increasing. Spinal diseases are degenerative changes in the bones, intervertebral discs, and ligaments of the spine, which eventually lead to the loss of their functions and seriously endanger human health.

[0004] Currently, many spinal treatments use traction. Traction refers to the use of the interaction between pulling force and counter-pulling force to pull the spine, so that the gap between vertebrae in the spine is increased, and the compression of nerve roots is relieved or reduced. Traction can also allow the spine to get sufficient rest, relieve muscle spasms, and reduce the load between vertebrae. It has a good rehabilitation treatment effect on spinal diseases.

[0005] However, current spinal traction uses specific medical equipment, which is not only expensive, but also requires treatment at a fixed point. It cannot be integrated into work and life, and it is impossible to complete spinal traction and correction while working and living. Summary of the invention

[0006] The purpose of the present invention is to provide a pillow core for a spinal traction pillow, so as to achieve traction and correction of the spine in daily work and life; and also to provide a spinal traction pillow using the pillow core, so as to achieve traction and correction of the spine in daily work and life.

[0007] To achieve the above-mentioned purpose, the technical solution of the pillow core for spinal traction pillow of the present invention is: a pillow core for spinal traction pillow, comprising:

[0008] The base has a front side facing the human body when in use;

[0009] A traction body, fixedly mounted on or integrally formed on the front side of the base body;

[0010] The traction body includes a traction ridge protruding forward, the traction ridge extends up and down, the traction ridge is used for the spine to abut against from front to back, and generates an upward pulling force on the spine opposite to gravity when in use;

[0011] An avoidance groove is provided at the intersection of the bottom and the front side of the traction body, and the avoidance groove is used for the lumbar vertebra of the spine to be embedded backward;

[0012] The bottom of the traction body includes inclined support bodies disposed on both sides of the avoidance groove, the two inclined support bodies extend from the traction ridges to the left and right sides respectively, each inclined support body is provided with an inclined ridge, and the two inclined ridges are used to abut against the left and right sides of the lumbar spine.

[0013] The beneficial effects of the present invention are as follows: due to the protruding arrangement of the traction ridges, the spine of the human body can be correspondingly abutted against the traction ridges when in use. When the human body slides downward to a certain extent under its own weight, the traction ridges can generate an upward pulling force on the spine, which helps to reduce the non-physiological pressure load of the spine, and has a good rehabilitation effect on intervertebral disc herniation and cervical spondylosis, spinal facet joint disorder, and spinal degenerative lesions. The pillow core for the spinal traction pillow provided by the present invention can be placed on a seat (including an office seat, a sofa, and a car seat), and can be used for traction in daily work and life. There is no need to use a special traction instrument for traction, and the traction of the spine can be integrated into daily work and life. After the avoidance groove is set, it can prevent the relatively fragile lumbar spine from being directly abutted, thereby effectively protecting the lumbar spine, and at the same time providing the lumbar spine with a reset movement space, which helps to reset the degenerative cone joint and the protruding intervertebral disc. In addition, the traction ridges can be well supported by two inclined support bodies, and the backward leaning force of the traction ridges is decomposed into the support forces in the left and right directions, forming a stable three-dimensional support system, and the spine can obtain a stable three-dimensional force system support.

[0014] As a further optimized solution, the traction body is a cone that is small in front and large in the back. The traction body includes inclined support surfaces located on both sides of the traction ridge. The inclined support surfaces extend from the traction ridge to the left and right sides. The inclined support surfaces are used to support the muscle groups on the left and right sides of the spine in the human waist and back.

[0015] The effect of this solution is that after the inclined support surface is set, after the human body leans back against the traction ridge, the parts of the waist and back located on both sides of the spine can also be supported on the inclined support surface, which assists the traction ridge in supporting the spine. In addition, the inclined support surfaces on both sides of the traction ridge will also provide a certain amount of expansion and contraction space for the erector spinae muscles on both sides of the spine to adjust and balance the physiological curvature of the spine and repair the disorder of the pyramidal facet joints. The inclined support surface can also play a good supporting and limiting role for the traction ridge, making it difficult for the traction ridge to deviate in the left and right directions.

[0016] As a further optimized solution, the inclined support surface is provided with a supporting ridge, the supporting ridge is extended up and down, and the front end of the supporting ridge is located behind the front end of the traction ridge.

[0017] The effect of this solution is that, on the one hand, after the supporting ridges are provided, they can better contact with the waist and back of the human body and bear the force; on the other hand, after the supporting ridges contact with the waist and back of the human body, they can increase friction and prevent the human body from sliding downward.

[0018] As a further optimized solution, the inclined support surface includes two parts arranged sequentially in the left and right directions, and the adjacent ends of the two parts in the left and right directions are staggered in the front and back directions to form the protruding support ridge at the junction of the two parts.

[0019] The effect of this solution is that the supporting ridges are formed by adopting a staggered arrangement, and the processing method is simple.

[0020] As a further optimized solution, in the left-right direction, the traction body has a structure that is narrow at the top and wide at the bottom.

[0021] The effect of this solution is that the traction body is narrow at the top and wide at the bottom, which prevents the back from sliding down when leaning back, and enhances the upward pulling force, thereby producing more effective support for the spine and traction on the physiological curvature of the spine.

[0022] As a further optimized solution, in the front-back direction, the traction ridges are arranged to extend obliquely along the extension direction of the physiological curvature of the spine.

[0023] The effect of this solution is that the traction ridges are arranged along the physiological curvature of the spine, which can better adapt to the spine and improve the traction effect.

[0024] As a further optimized solution, a side support body is provided on the front side of the base body, and two side support bodies are provided, and the side support bodies are respectively arranged on the left and right sides of the traction body, and the side support bodies are used to cooperate and rest against the two sides of the waist and back of the human body.

[0025] The effect of this solution is that the side support bodies can effectively support and position both sides of the waist and back, and cooperate with the backward force and the upward pulling force to form a multi-dimensional force system for the waist and back.

[0026] As a further optimized solution, the base body has a rear side surface opposite to the front side surface, and a rear support body for leaning against a seat back is provided at the bottom of the rear side surface.

[0027] The effect of this solution is that after the rear support body is provided, it can be filled into the space where the seat surface and the chair back intersect on the seat, preventing the pillow core from being deformed and weakening the traction effect.

[0028] The technical solution of the spinal traction pillow of the present invention is: a spinal traction pillow, comprising a pillow core and a cover wrapped around the outside of the pillow core, wherein the pillow core comprises:

[0029] The base has a front side facing the human body when in use;

[0030] A traction body, fixedly mounted on or integrally formed on the front side of the base body;

[0031] The traction body includes a traction ridge protruding forward, the traction ridge extends up and down, the traction ridge is used for the spine to abut against from front to back, and generates an upward pulling force on the spine opposite to gravity when in use;

[0032] An avoidance groove is provided at the intersection of the bottom and the front side of the traction body, and the avoidance groove is used for the lumbar vertebra of the spine to be embedded backward;

[0033] The bottom of the traction body includes inclined support bodies disposed on both sides of the avoidance groove, the two inclined support bodies extend from the traction ridges to the left and right sides respectively, each inclined support body is provided with an inclined ridge, and the two inclined ridges are used to abut against the left and right sides of the lumbar spine.

[0034] The beneficial effects of the present invention are as follows: due to the protruding arrangement of the traction ridges, the spine of the human body can be correspondingly abutted against the traction ridges when in use. When the human body slides downward to a certain extent under its own weight, the traction ridges can generate an upward pulling force on the spine, which helps to reduce the non-physiological pressure load of the spine, and has a good rehabilitation effect on intervertebral disc herniation and cervical spondylosis, spinal facet joint disorder, and spinal degenerative lesions. The pillow core for the spinal traction pillow provided by the present invention can be placed on a seat (including an office seat, a sofa, and a car seat), and can be used for traction in daily work and life. There is no need to use a special traction instrument for traction, and the traction of the spine can be integrated into daily work and life. After the avoidance groove is set, it can prevent the relatively fragile lumbar spine from being directly abutted, thereby effectively protecting the lumbar spine, and at the same time providing the lumbar spine with a reset movement space, which helps to reset the degenerative cone joint and the protruding intervertebral disc. In addition, the traction ridges can be well supported by two inclined support bodies, and the backward leaning force of the traction ridges is decomposed into the support forces in the left and right directions, forming a stable three-dimensional support system, and the spine can obtain a stable three-dimensional force system support.

[0035] As a further optimized solution, the traction body is a cone that is small in front and large in the back. The traction body includes inclined support surfaces located on both sides of the traction ridge. The inclined support surfaces extend from the traction ridge to the left and right sides. The inclined support surfaces are used to support the muscle groups on the left and right sides of the spine in the human waist and back.

[0036] The effect of this solution is that after the inclined support surface is set, after the human body leans back against the traction ridge, the parts of the waist and back located on both sides of the spine can also be supported on the inclined support surface, which assists the traction ridge in supporting the spine. In addition, the inclined support surfaces on both sides of the traction ridge will also provide a certain amount of expansion and contraction space for the erector spinae muscles on both sides of the spine to adjust and balance the physiological curvature of the spine and repair the disorder of the pyramidal facet joints. The inclined support surface can also play a good supporting and limiting role for the traction ridge, making it difficult for the traction flange to deviate in the left and right directions.

[0037] As a further optimized solution, the inclined support surface is provided with a supporting ridge, the supporting ridge is extended up and down, and the front end of the supporting ridge is located behind the front end of the traction ridge.

[0038] The effect of this solution is that, on the one hand, after the supporting ridges are provided, they can better contact with the waist and back of the human body and bear the force; on the other hand, after the supporting ridges contact with the waist and back of the human body, they can increase friction and prevent the human body from sliding downward.

[0039] As a further optimized solution, the inclined support surface includes two parts arranged sequentially in the left and right directions, and the adjacent ends of the two parts in the left and right directions are staggered in the front and back directions to form the protruding support ridge at the junction of the two parts.

[0040] The effect of this solution is that the supporting ridges are formed by adopting a staggered arrangement, and the processing method is simple.

[0041] As a further optimized solution, in the left-right direction, the traction body has a structure that is narrow at the top and wide at the bottom.

[0042] The effect of this solution is that the traction body is narrow at the top and wide at the bottom, which prevents the back from sliding down when the waist and back are leaned back, and enhances the upward pulling force, thereby producing more effective support for the spine and traction on the physiological curvature of the spine.

[0055] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0056] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0057] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0058] Specific embodiment 1 of the pillow core for spinal traction pillow of the present invention:

[0059] like Figures 1 to 3 As shown, the pillow core for spinal traction pillow hereinafter referred to as the pillow core, the pillow core in this embodiment is formed by foaming polyurethane, latex, and elastic material in one step. The pillow core as a whole includes a base 100, a traction body 200, a side support body 300, and a rear support body 400. It should be noted that these parts are actually an integrated structure, and they are artificially divided into multiple parts due to their different functions and effects. The base 100 is the basis of the traction body 200, the side support body 300 and the rear support body 400. When in use, the base 100 is placed on the seat, and the rear support body 400 and the base 100 lean against the backrest of the seat. In this embodiment, the side of the base 100 facing the human body when in use is defined as the front side.

[0060] like Figure 1 , Figure 2 and Figure 3 As shown, the traction body 200 is integrally formed on the front side of the base 100, and is a cone with a small front and a large rear. The traction body 200 has a traction ridge 21 protruding forward. The traction body 200 also includes inclined support surfaces 22 located on the left and right sides of the traction ridge 21. The inclined support surfaces 22 extend obliquely from the traction ridge 21 to the left and right sides. Figure 3 It can be seen that the traction rib 21 is arranged in an inclined manner in the up and down direction, with the upper end of the traction rib 21 being closer to the back and the lower end being closer to the front. This arrangement allows the traction rib 21 to extend along the physiological curvature of the spine and to abut against the spine well.

[0061] Depend on Figure 1 and Figure 3It can be seen that in the left-right direction, the traction body 200 is a structure that is narrow at the top and wide at the bottom, with the bottom being wider, and has a better supporting and traction effect on the spine.

[0062] like Figure 1 As shown, an escape groove 24 is provided at the intersection of the bottom and the front side of the traction body 200. The escape groove 24 is a conical structure as a whole. Two inclined support bodies 26 are formed at the lower end of the traction body 200. The two inclined support bodies 26 extend obliquely from the traction rib 21 to the left and right sides. The escape groove 24 is located directly below the traction rib 21. The escape groove 24 and the traction body 200 form two inclined ribs 25, wherein the two inclined ribs 25 both extend obliquely from the traction rib 21 to the left and right sides. The two inclined ribs 25 decompose the backward leaning force of the waist and back of the human body into left and right supporting forces, and the support is more stable.

[0063] The function of the avoidance groove 24 is to avoid the lumbar spine. When in use, the lumbar spine that bends backward can be embedded in the avoidance groove 24 to avoid direct contact with the relatively fragile lumbar spine, thereby avoiding damage to the lumbar spine. After the lumbar spine is embedded in the avoidance groove 24, it can provide movement space for the lumbar spine to be reset, which is helpful for the reset of degenerative cone joints and protruding intervertebral discs.

[0064] like Figure 1 and Figure 2 As shown, a supporting ridge 23 is also provided on the inclined supporting surface 22, wherein the front end of the supporting ridge 23 is located behind the front end of the traction ridge 21. The supporting ridge 23 passes through the traction body 200 from top to bottom, and the functions of the supporting ridge 23 are: 1) when the waist and back of the human body lean on the traction body 200, under the action of the back force, the traction ridge 21 abuts against the spine, and after the traction body 200 is compressed, the supporting ridge 23 abuts against the waist and back, and the supporting ridge 23 can bear a part of the back force; 2) the supporting ridge 23 can increase the friction between the waist and back of the human body and the pillow core to prevent the human body from sliding down.

[0065] In this embodiment, the supporting ridge 23 is formed in the following manner: Figure 1 and Figure 2 It can be seen that the inclined supporting surface 22 includes two parts, namely a first part 221 and a second part 222. The first part 221 and the second part 222 are both inclined surfaces. The first part 221 is close to the traction ridge 21. The two parts are arranged sequentially in the left and right directions, and the adjacent ends of the two parts are staggered. The inner end of the second part 222 is located on the front side of the first part 221, thereby forming the above-mentioned supporting ridge 23.

[0066] like Figures 1 to 3As shown, a side support body 300 is also provided on the front side of the base body 100. There are two side support bodies 300, which are respectively arranged at the two ends of the traction body 200. The two side support bodies 300 are arranged opposite to each other. When the human body's waist and back lean back, the two side support bodies 300 can clamp the two sides of the human body's waist and back to achieve positioning, and cooperate with the force generated by the traction body 200 to form a multi-dimensional force system for the waist and back, which is more stable.

[0067] To ensure that the pillow core is supported and placed on the seat, the pillow core is supported and stable as a whole, and is not easily deformed when the human body leans back. A rear support body 400 is arranged at the bottom rear side of the base 100, and the rear support body 400 can be supported at the junction of the backrest and the seat surface of the seat when in use.

[0068] It should be noted that, when in use, a cover body is sheathed on the outside of the pillow core of this embodiment, thereby forming a spinal traction pillow.

[0069] The use process of the present invention is as follows: the spine traction pillow is placed upright on a seat (including office chairs, sofas and car seats), the human lumbar spine is first fitted into the avoidance groove 24, and then the traction body 200 is leaned back, and the spine and the traction ridge 21 are pressed against each other. When in use, the human body leans back and moves downward, and the traction ridge 21 generates an upward pulling force on the spine. The human spine is rehabilitated during rest, and the whole process helps to reduce the non-physiological pressure load of the spine, and has a good rehabilitation effect on intervertebral disc herniation, cervical spondylosis, spinal facet joint disorder, and spinal degenerative lesions.

[0070] Specific embodiment 2 of the pillow core for spinal traction pillow of the present invention:

[0071] like Figure 4 As shown, the traction body 600 is integrally formed on the front side of the base 500, and the traction body 600 includes a traction ridge 61 located in the center, and also includes inclined support surfaces 62 located on the left and right sides of the traction ridge 61. The difference from the embodiment 1 is that in this embodiment, the inclined support surface 62 is a smoothly transitioned inclined surface, and no supporting ridge is provided on the inclined support surface 62.

[0072] Specific embodiment 3 of the pillow core for spinal traction pillow of the present invention:

[0073] In the first embodiment, in order to fill the space at the intersection of the seat surface and the backrest of the chair, a rear support body is arranged at the rear of the base body. In the present embodiment, the rear support body can be eliminated.

[0074] Specific embodiment 4 of the pillow core for spinal traction pillow of the present invention:

[0075] In Example 1, in order to achieve multi-directional support for the waist and back, a side support body is provided. It should be noted that the main purpose of the present invention is to achieve traction on the spine. If only this purpose is to be achieved, the side support body can be cancelled.

[0076] Specific embodiment 5 of the pillow core for spinal traction pillow of the present invention:

[0077] In Example 1, the traction body is a structure that is narrow at the top and wide at the bottom in the left-right direction. In this embodiment, when the width of the traction body can meet the traction requirements, the traction body can be designed to be an equal-width structure in the left-right direction.

[0078] Specific embodiment 6 of the pillow core for spinal traction pillow of the present invention:

[0079] In Example 1, an avoidance groove is provided at the bottom of the traction body, thereby forming a left-right support mode and avoiding the lumbar spine, providing space for the resetting movement of the lumbar spine. In this embodiment, the avoidance groove can be eliminated, so that the traction body is a structure with an overall smooth transition from top to bottom.

[0080] Specific embodiment 7 of the pillow core for spinal traction pillow of the present invention:

[0081] In Example 1, inclined support surfaces are provided on both sides of the traction ridge, and the inclined support surfaces can support the left and right sides of the spine in the waist and back, and at the same time, support the traction ridges on both sides to make it more stable. In this embodiment, the inclined support surfaces can be eliminated, that is, the traction ridges are protruding, and there is no smooth transition between them and other parts of the traction body, and an obvious step structure is formed at the intersection.

[0082] Specific embodiment 8 of the pillow core for spinal traction pillow of the present invention:

[0083] In the above-mentioned embodiments, the traction body is integrally formed on the base. In this embodiment, the traction body and the base can be manufactured separately and then fixed together by gluing or other methods.

[0084] Specific embodiments of the spine traction pillow of the present invention:

[0085] The spinal traction pillow comprises a pillow core and a cover wrapped around the pillow core. The structure of the pillow core is consistent with the structure of the spinal traction pillow in the above embodiments, and will not be described in detail here.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
