Background

People sit in front of desks and on automobile seats for a longer time, and the occurrence probability of spinal diseases among people is higher and higher. Spinal diseases are degenerative changes of bones, intervertebral discs and ligaments of the spine, which finally cause the function of the spine to be lost in a decline way, and the spine seriously harms human health.

At present, the spine is treated by adopting a traction mode, the traction is to utilize the interaction of traction force and counter-traction force to draw the spine, so that the gap between the spines in the spine is increased, the extrusion to nerve roots is relieved or reduced, the spine can be fully rested by traction, the muscle spasm is relieved, the load of the spines is lightened, and the spine disease rehabilitation therapy effect is better.

However, the existing spinal traction adopts specific medical equipment, so that the cost is high, the treatment needs to be carried out at fixed points, the spinal traction cannot be integrated into the work and the life, and the traction and the correction of the spinal column cannot be completed at the same time of the work and the life.

The features and properties of the present invention are described in further detail below with reference to examples.

The invention relates to a concrete embodiment 1 of a pillow inner for a spinal traction back cushion, which comprises the following components:

as shown in fig. 1 to 3, the pillow core for the spinal traction headrest is a pillow core, and the pillow core in this embodiment is formed in one step by foaming polyurethane, latex and elastic materials. The pillow core integrally includes a base body 100, a traction body 200, a side support 300, and a rear support 400, and it should be noted that these parts are actually an integral structure, and are artificially divided into a plurality of parts due to their functions and effects. The base 100 is the basis for the traction body 200, the side supports 300 and the rear support 400, and in use the base 100 is placed on a seat, and the rear support 400, the base 100 rest 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.

As shown in fig. 1, 2 and 3, the pulling body 200 is integrally formed on the front side of the base body 100, and is a cone with a small front part and a large rear part, so that the pulling body 200 has a pulling rib 21 protruding forward, the pulling body 200 further includes inclined support surfaces 22 located on the left and right sides of the pulling rib 21, and the inclined support surfaces 22 extend obliquely from the pulling rib 21 to the left and right sides. As can be seen from fig. 3, the traction protruding ridge 21 is arranged in an inclined manner in the vertical direction, and the upper end of the traction protruding ridge 21 is located behind the lower end of the traction protruding ridge 21, so that the traction protruding ridge 21 can extend along the physiological curvature of the spine and can be well abutted against the spine correspondingly.

As can be seen from FIGS. 1 and 3, the traction body 200 has a structure with a narrow upper part and a wide lower part in the left-right direction, and a wider bottom, so that the traction body has a better supporting and traction effect on the spine.

As shown in fig. 1, an avoiding groove 24 is formed at the intersection of the bottom and the front side of the traction body 200, the avoiding groove 24 is tapered as a whole, two inclined support bodies 26 are formed at the lower end of the traction body 200, and the two inclined support bodies 26 extend obliquely from the traction ridge 21 to the left and right sides. The avoiding groove 24 is located right below the traction lug 21. The avoiding groove 24 and the traction body 200 form two inclined convex ribs 25, wherein the two inclined convex ribs 25 extend towards the left side and the right side from the traction convex rib 21 in an inclined manner, and the two inclined convex ribs 25 decompose the back-leaning force of the waist and the back of the human body into left and right supporting forces, so that the supporting is more stable.

Dodge the effect of groove 24 and be can dodge the waist end vertebra, in the groove 24 can be dodged to the back bending waist end vertebra during the use, avoid producing directly to lean on comparatively fragile waist end vertebra to damage the waist end vertebra. After the lumbar vertebra is embedded into the avoiding groove 24, a moving space can be provided for the reduction of the lumbar vertebra, and the reduction of the degenerative cone joint and the protruded intervertebral disc is facilitated.

As shown in fig. 1 and 2, a supporting rib 23 is further provided on the inclined supporting surface 22, wherein the forward end of the supporting rib 23 is located behind the forward end of the drawing rib 21. The support rib 23 vertically penetrates the traction body 200, and the support rib 23 has the following functions: 1) when the waist and the back of the human body lean against the traction body 200, the traction convex rib 21 correspondingly leans against the spine under the action of the backward leaning force, the support convex rib 23 leans against the waist and the back after the traction body 200 is pressed, and the support convex rib 23 can bear part of the backward leaning force; 2) the supporting convex ridges 23 can increase the friction force between the waist and the back of the human body and the pillow inner, and prevent the human body from sliding downwards.

In the present embodiment, the supporting projected ridges 23 are formed in the following manner: as can be seen from fig. 1 and 2, the inclined support surface 22 includes two portions, a first portion 221 and a second portion 222, respectively, the first portion 221 and the second portion 222 are both inclined surfaces, the first portion 221 is adjacent to the traction ridge 21, the two portions are sequentially arranged in the left-right direction, adjacent ends of the two portions are staggered, and the inner end of the second portion 222 is located at the front side of the first portion 221, thereby forming the support ridge 23.

As shown in fig. 1 to 3, a side support 300 is further disposed at the front side of the base 100, the number of the side supports 300 is two, and the two side supports 300 are respectively disposed at two ends of the traction body 200, the two side supports 300 are oppositely disposed, when the back of the human body, the two side supports 300 can abut against and clamp two sides of the back of the human body, so as to achieve positioning, and cooperate with an acting force generated by the traction body 200 to form a multi-dimensional force system for applying force to the back of the back, which is more stable.

In order to ensure that the pillow inner is supported and placed on the seat, the whole pillow inner is stably supported and is not easy to deform after a human body leans against. At the bottom rear side of the base 100 there is a rear support 400, the rear support 400 being able to be supported in use at the interface of the back and the seat face of the seat.

It should be noted that, in use, the pillow core of this embodiment is covered with a cover body to form a spinal traction headrest.

The using process of the invention is as follows: the spine traction back cushion is vertically placed on a seat (comprising an office seat, a sofa and an automobile seat), the human body waist-bottom spine is firstly attached to the avoiding groove 24 and leans against the traction body 200 after following the situation, the spine and the traction convex edges 21 are mutually abutted, and when the spine traction back cushion is used, the human body leans against the lower part and moves downwards, and the traction convex edges 21 generate upward traction force on the spine. The human spine is recovered during rest, the whole process is beneficial to reducing the non-physiological pressure load of the spine, and the rehabilitation curative effect on the protrusion of intervertebral disc, cervical spondylosis, vertebral facet joint disorder and spinal degenerative change is better.
