2. Description of the Related Art In general, a cervical spine orthosis to be attached to the cervical spine due to cervical spine injuries, etc. In addition, there are strut appliances that support four turnbuckle-type struts and fix the cervical spine, and collars that simply wrap a band with a predetermined width of one or two around the neck. However, as in the former case, in a type in which two struts are provided in the chin rest and two struts are provided in the occipital receiving part, it is difficult to balance each strut, and it is time-consuming and troublesome to mount. It was In the latter case, it is easy to mount because it is simply wrapped around the collar, but the cervical spine cannot be fixed at the desired angle, and only mild whiplash can be achieved.

[0003]

Further, recently, a simple cervical spine orthosis having improved the above defects has appeared. For example, in FIG.
As shown in Fig. 1, plastic substrate a and Styrofoam plate b

And a pair of turnbuckle type adjustment support rods 16 are connected to both sides of the facing space 15 of the back support plate portion 2 to form a cervical spine orthosis 17 with the entire configuration thereof. In this case, the connecting holes 18 formed in the upper connecting piece 5 and the lower connecting piece 10 have a plurality of connecting holes 18 (two in the figure) vertically arranged at the center thereof as shown in FIG. It becomes.

To explain this action, when attaching the cervical spine orthosis 17, first, a hook-loop type fastener type adhesive tape is formed by band-tightening to the divided jaw receiving portions 9, 9 on the upper cervical spine main body side located on the upper and lower front sides. 13 and the hook-loop type fastener type adhesive tape 14 band-tightened to the divided breast pads 4, 4 on the lower cervical vertebra main body side, the hooks and loops of the hooks are separated from each other by releasing the claw engagement from each other, and the front is opened forward. (See FIG. 2).

In this state, the divided jaw receiving portions 9 and 9 and the divided chest pad portions 4 and 4 are spread from side to side and fitted from the rear to the front of the body, and the left and right shoulders A are both bent downward and hung on the shoulders. When placed so as to straddle the portions 3 and 3, the backrest plate portion 2 is located at the back portion B, and the two divided breastplate portions 4 and 4 are applied to the chest portion C,
On the other hand, the occipital region D is exposed to the occipital region receiving portion 7 on the side of the upper cervical vertebra main body, and the jaw portions E are set on the stepped portions 9a, 9a of the divided jaw receiving portions 9, 9 at the front end half by half (see FIG. 5). ). After that, the hook-loop type fastener tapes 12 and 12 on the front side of the split breastplates 4 and 4 are attached to the hook-loop type fasteners 12 and 12 on the front side.
The hooks on the back side of the hook loop type fastener type adhesive tape 13 are hooked to the hook loop type fasteners 12 and 12 of the split jaw receiving portions 9 and 9 that receive the one jaw portion E while being fixed by tightening The jaw E is fixed by pressing the loop fastener 12 'with a claw engagement and band tightening, and at this time, the side neck receiving portion 8 is located at the lower part of the side neck F, and the side inclination is also regulated, and the entire cervical vertebrae is controlled. Is fixed.

In this case, the degree of forward flexion or rearward flexion of the head is determined by the two turnbuckle type adjustment support rods 1 arranged rearward.
The degree of opening of the facing space 15 in the occipital region 7 and the back support plate 2 is easily adjusted according to the amount of extension of 6 and 16, and the upper cervical vertebra main body 6 can be inclined with respect to the lower cervical vertebra main body 1 by a desired bending value. In addition, the inclination adjustment of the side neck F is performed by adjusting the plurality of connecting holes 18 of the upper connecting piece 5 and the connecting holes 18 of the lower connecting piece 10.
Hole is selected (for example, one connecting hole 18
Is set to a higher position and the other connecting hole 18 is set to a lower position to check hole matching), and the connecting bolt 11 is inserted therethrough, whereby the upper cervical vertebra main body 6 can be fixed to the lower cervical vertebra main body 1 in an inclined lateral bending mode.

Further, when it is desired to move the jaws a little after eating after fixing the neck, by removing only the hook-loop type fastener type adhesive tape 13 in which the split jaw receivers 9 and 9 are band-tightened, the split jaws can be divided. It is possible to move the chin on the chin rests 9, 9.

7 and 8 show another embodiment in which the connecting means of the upper connecting piece 5 and the lower connecting piece 10 is a two-point connection using two connecting bolts. In this case, the lower connecting piece 10
A positioning connecting hole 19 and a laterally elongated hole 20 are formed on the left and right sides (inside), and a plurality of adjusting connecting holes 21 (3 in the figure) corresponding to the connecting holes 19 are formed on the left and right sides of the upper connecting piece 5 (outside).
Upper and lower connecting pieces 5 are arranged in a vertical direction, and arcuate vertically elongated holes 22 that are orthogonal to the horizontally elongated hole 20 are bored, and are stacked.
In the lower connecting piece portion 10, a connecting bolt 11 inserted into a single positioning connecting hole 19 is passed through a predetermined hole of a plurality of connecting holes 21 of the lower connecting piece portion 5, and a nut 11 'is attached to the tip thereof.

That is, the upper connecting piece 5 and the lower connecting piece 10
Since the connection is made to a two-point connection in which the connecting bolts 11 and 11 are respectively inserted at the left and right positions, the upper connecting piece portion 5 and the lower connecting piece portion 10 can be easily fixed with only this connecting bolt. At this time, the lateral bending degree is adjusted by selecting a single connecting hole 19 and a plurality of adjusting connecting holes 21 at the left and right positions and moving the intersection of the horizontally long hole 20 and the arcuate vertically long hole 22 (differently). By connecting with the connecting bolts 11, it is possible to easily adjust the tilt of the side neck receiving portion 8 on one side as a whole.

Further, in this case, two connecting bolts 11
Since the upper connecting piece 5 and the lower connecting piece 10 are securely fixed by (two-point connection), they are mounted in the facing space 15 between the occipital region receiving portion 7 and the back contact plate portion 2 which is required in the above embodiment. The pair of turnbuckle type adjustment support rods 16 can be omitted, and the cervical orthosis 17 can be made lightweight. In this mode, since there is nothing between the occipital region receiving portion 7 and the back contact plate portion 2, a large facing space 15 is obtained,
Even if the user takes a sleeping posture, the pillow is fitted into the facing space 15 to a large extent, and the pressure on the back of the head is minimized. Of course, since the jaws are still received by the band-separated split jaw receivers 9 and 9, when the jaws are to be moved for meals or the like, the hook-loop type fastener type adhesive tape 13 is used as described above. Just remove it.

At the peripheral edges of the lower cervical vertebra main body 1 and the upper cervical vertebra main body 6, styrofoam 23 which is superposed on the inner side is slightly projected with respect to the plastic plate 24 serving as a substrate so as to adopt a buffer structure.

[0022]

As described above, in the cervical spine orthosis of the present invention, the lower cervical vertebra main body which straddles the shoulder portion and the upper cervical vertebra main body which directly receives the cervical vertebrae are connected to each other by projecting connecting piece portions. One connecting bolt (one-point connection) is inserted and fixed with a turnbuckle type adjustment support rod that passes over the occipital region receiving part and the backrest plate part facing space, or only two connecting pieces are connected to the left and right positions. Insert the bolt (two-point connection), and the jaw receiving part formed on the front edge of the upper cervical vertebra main body is divided into left and right parts, and band-tightened with a hook loop type fastener type adhesive tape. Since the structure is divided into left and right and the band is tightened with the same adhesive tape, the cervical spine orthosis can be attached to the cervical part by expanding the jaw receiving part and the chest part that are divided forward, and it can be easily attached.
To fix the cervical vertebra, the hook and loop fastener type adhesive tape may be simply band-tightened to the divided jaw receiving portion and the divided breast pad portion. If you want to move your jaw after fixing, such as by eating or taking medicine, you can easily deal with it by simply tightening and releasing the band of the hook-loop type fastener type adhesive tape. The forward bending or the backward bending of the cervical vertebra can be adjusted by feeding out the two turnbuckle type adjustment supporting rods on the back, or a plurality of connecting holes may be selected in the two-point connection without using the adjusting supporting rods. Moreover, the lateral bending mode to the left and right can be easily dealt with by selecting the displacement of the plurality of connecting holes of the left and right connecting pieces. Further, even if the sleeping posture is taken, since two turnbuckle type adjustment support rods are present on both sides of the space facing the occipital support part and the back support plate part (not directly behind the occipital support part), a pillow or the like is provided on the adjustment support bar. However, there is little pressure on the back of the head and it is possible to sleep comfortably. Of course, the turnbuckle type adjustment support rod omitted type does not have the above-mentioned pressing action, and the occipital region receiving portion may be thin and may be a lightweight type. Furthermore, since the lower cervical vertebra main body and the upper cervical vertebra main body are connected by a connecting structure in which the connecting piece portions on both sides are overlapped with each other, the periphery excluding the connecting piece portion becomes a substantially large space, which is breathable and comfortable to wear. Has the effect of becoming.
