BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view of the entire cervical traction device 3 according to an embodiment of the present invention, and FIG. 2 is an explanatory view of the cervical traction device 2 in use. This cervical traction device 3 is a cervical traction device 2

, Traction machine 4, prop 5, guide roller 6, wire 7, hook 8, chair 9.

[0023] The cervical traction device 2 is a cervical traction device 2 having a belt 1 attached to the head of a subject in a sitting posture or standing at an appropriate angle, and the belt 1 is a posterior cervical spine of the subject. The two heads are sandwiched from the vicinity of the face so that they can be pulled forward and upward.

The cervical traction device 2 includes a belt 1 and a length adjusting member 10. Belt 1 is a flat belt made of an appropriate material. The length adjusting member 10 is a metal ring.

[0025] The front upper part from both heads of the subject to which the belt 1 hits is the front support part, and the vicinity of the cervical vertebra rear part is the rear support part. The part that hits the front support part of the belt 1 is provided with an elastic member (not shown) that is used as a mattress material on the inside, so that the height of the front of the auricle is increased. Secured and comfortable cervical traction for the subject without crushing the pinna.

[0026] The cervical traction device 2 has a function of adjusting the length of the belt 1 by moving the length adjusting member 10 that has passed the belts 1 on both sides up and down. It can be freely adjusted to the size. The surface of the belt 1 has a rough surface structure with irregularities, and the length adjusting member 10 can be fixed.

[0027] The traction direction of the cervical vertebra by the cervical traction device 2 is an arbitrary angle with respect to the vertical direction (Y) (

(Θ) is inclined backward. The tip of the side arm installed on the prop 5 of the traction machine 4

1

From the guide roller 6 provided in the section, the front hook 8 and the cervical traction device 2 are arranged in a straight line along the traction direction.

[0028] In the cervical traction orthosis 2, the belt 1 passes through the aforementioned part of the subject, and the subject feels uncomfortable. It is desirable that the belt 1 has an appropriate flexibility so that it can be pulled without giving. If the width of the belt 1 is too narrow, the resting state of the muscles around the head and neck cannot be obtained due to discomfort due to concentration of traction force, and if it is too wide, the freedom of extension of the upper cervical spine is inhibited. It is desirable that the width be an appropriate width so as not to cause a problem.

[0029] When an appropriate force is applied from a predetermined direction to the posterior surface of the occipital bone by the belt 1 of the cervical traction device 2, the upper cervical vertebra connection portion extends and the skull tends to be bent forward, but the front of the head is surrounded. The belt 1 is prevented from detaching the cervical tractor pulling device 2 from the radial arch and the frontal bone, which reversely bends the skull.

[0030] Although the material of the cervical traction device 2 can be leather or cloth, it can be variously modified within a range not departing from the gist of the present invention by having appropriate softness and width such as, for example, synthetic resin. It can be implemented. The same effect can be obtained by a force using a metal ring as the length adjusting member 10 for tightening the head of the cervical traction device 2 to the head, for example, a hook, and is not limited to this configuration. The position of the head and neck of the cervical traction device 2 is described in detail as a reference position, but some errors can obtain the same effect, and are not limited to this.

[0031] In addition, the length adjusting member 10 of the cervical traction device 2 may have a shape in which rings are arranged at both ends of a single bar having an appropriate length, as shown in FIG. In this case, the distance between the belts 1 that sandwich the head from both sides is widened, and the sense of incongruity to the auricles can be removed.

The traction machine 4 is driven by a motor and pulls the cervical traction orthosis 2 through the hook 8 by winding the wire 7. The angle at which the cervical traction device 2 is pulled can be appropriately set by changing the position of the guide roller 6.

[0033] The chair 9 includes a backrest part 11, a headrest part 12, an armrest part 13, and a seat part 14, and a predetermined angle (Θ) of the cervical traction device 2 given to the vertical direction (Y). )

1 Preliminary angle (Θ) is given to the backrest 11 and tilted backward to

2

The relationship between the cervical traction device 2 and the position of the subject's head is defined, and a frictional force is generated between the cervical traction device 2 and the lower part of the subject's occipital nodule.

[0034] When the support part of the cervical traction device 2 is obtained only at the lower part of the occipital nodule, sufficient fixation is obtained. However, detachment of the cervical traction device 2 may occur, but by using a flexible mat material for the chair 9, the cervical traction device 2 is prevented from being detached above the skull. be able to.

[0035] In this embodiment, the backrest 11 is inclined backward to a predetermined angle (Θ) in consideration of cost.

2 Although it is fixed in a slanted state, the angle can be adjusted by the reclining means, and the cervical traction treatment can be made more comfortable by adjusting the cervical traction direction at an optimum angle corresponding to the reclining angle. It is also possible to do.

The headrest portion 12 is provided above the backrest portion 11 via the coupling mechanism 15.

The coupling mechanism 15 includes an upper support bar 16, a lower support bar 17, an upper hinge 18, and a lower hinge 19, and the upper hinge 18 is disposed between the back side of the headrest 12 and the upper end of the upper support bar 16. The lower hinge 19 is disposed between the lower end portion of the upper support bar 16 and the upper end portion of the lower support bar 17 so that the degree of vertical extension of the headrest portion 12 can be changed and adjusted. Further, the lower hinge 19 is provided with a rotation adjusting function, and the headrest portion 12 is configured to be able to handle subjects of all symptoms and physiques.

[0037] On the other hand, the upper hinge 18 of the headrest portion 12 has a function of freely tilting backward to change and adjust the bending angle thereof, so that the head and neck muscles are always prevented from obstructing the extension action of the cervical spine. It is configured to ensure a resting state.

[0038] The armrest portion 13 makes it possible to avoid emergency discomfort during traction of the cervical spine and maintain a left-right equilibrium state with respect to the traction direction. In addition, the armrest portion 13 can be easily seated and unseated by providing a rotary opening / closing function.

[0039] Further, in the above description, it is assumed that two hinges are attached as means for freely tilting the headrest portion 12 at the upper hinge 18, so that a resting state of the muscles around the head and neck can be obtained. The same effect can be obtained by attaching three hinges, and the structure of the headrest portion 12 is not limited to this.

[0040] It should be noted that the chair 9 can be variously substituted within a range not departing from the gist of the present invention, such as a treatment chair in a dental clinic, a barber / beauty chair in a beauty salon, and the like.

[0041] In addition, the cervical traction device 3 can be used as an auxiliary treatment for occlusion treatment in a mandibular deviation patient who has cervical spondylosis. That is, the cervical spine is A subject who appears to be bent can correct a robust cervical curvature by performing cervical traction therapy along with occlusion. As described above, the conventional cervical traction device has a problem in compressing the most important temporomandibular joint in occlusion treatment, but the cervical traction device 3 of the present invention does not have such a problem. Since the chair 9 can be used as a treatment chair in a dental clinic, it can be used for both occlusion treatment and cervical traction therapy, and can be used particularly effectively in a dental clinic.

[0042] Furthermore, it is possible to provide a space in which the traction machine 4, the cervical traction device 2 and the like can be built under the seat 14 of the chair 9 so that the space can be made compact when not in use. The

Next, the state of the subject when using the cervical traction device 3 will be described.

[0044] As shown in Figs. 1 and 2, when the belt 1 of the cervical traction device 2 is worn on the subject's head, the position of the head and neck is the rearmost part of the upper cervical vertebra, which is the rearmost position. The belt 1 that crosses here and extends to the left and right of the head passes through the lower part of the bilateral occipital papilla, passes through the lower part of both auricles, and exits anteriorly and upwardly, sandwiching the bilateral radial arches. The belt 1 extending to the left and right passes through the length adjusting member 10 toward one place and is connected to the hook 8 at the tip of the wire 7.

[0045] FIGS. 4 (to (d) show the angle (Θ) of the cervical traction with the cervical traction device 2 with respect to the vertical direction (Y).

It is a schematic diagram showing the change in head position due to the difference of 1.

[0046] FIG. 4 (a) shows a resting state in which no traction force is applied to the cervical traction device 2, and the headrest portion 12 is adjusted up and down and back and forth to ensure that the subject's head and neck muscles are at rest. It can be done.

[0047] FIG. 4 (b) shows a case where the anterior force is pulled more than the ideal pulling direction, the head position is bent backward, and the subject's upper cervical vertebra is uncomfortable and is inappropriate.

[0048] FIG. 4 (c) shows an ideal case where it is pulled in the same direction as the long axis of the cervical vertebra.

[0049] Fig. 4 (d) shows a case where the backward force is also pulled rather than the ideal pulling direction, and the head position is bent forward, causing discomfort to the auricle and inappropriate.

[0050] The predetermined angle (Θ) given to the backrest 11 of the chair 9 is cervical below the axial vertebra.

2

By adjusting the angle of the cervical vertebrae traction direction (Θ) Thus, the disc can be pulled without causing discomfort in the extension of the cervical spine joint.

FIGS. 5 (to (c) are schematic views showing changes in head position caused by the difference in length of the cervical traction device 2.

[0052] FIG. 5 (a) is a case where the cervical traction device 2 is shorter than the ideal cervical traction device 2, and the head position is bent back, causing discomfort on the upper cervical vertebra and unsuitable.

FIG. 5 (b) shows the case where the cervical traction device 2 has an ideal length. The head position does not rotate, and the cervical vertebra traction device 2 is pulled in substantially the same direction as the cervical vertebra long axis.

FIG. 5 (c) shows a case where the cervical traction device 2 is longer than the ideal cervical traction device 2, and the head position is bent forward, causing discomfort to the auricle and inappropriate.

[0055] By appropriately adjusting the length, the cervical traction device 2 adjusts the head position of the subject to enable desired comfortable traction.

FIGS. 6 (a) to 6 (c) are schematic diagrams showing the influence on the auricle and the upper neck by the difference in the height of the headrest portion 12 of the chair 9.

[0057] FIG. 6 (a) shows that the headrest portion 12 is too high, and discomfort caused by the cervical traction device 2 occurs in the auricle and is inappropriate.

[0058] Fig. 6 (b) shows the case where the headrest portion 12 is at an ideal height.

[0059] Figure 6 (c) shows that when the headrest 12 is too low, a cervical vertebral kyphosis may occur, which may worsen nerve root symptoms on the posterior surface of the cervical spine. Goodbye

[0060] That is, the degree of flexion of the occipital atlanto-vertebral joint changes depending on the height of the headrest portion 12 in which the force is in the same direction at the second cervical vertebra or the like regardless of the height of the headrest portion 12.

[0061] The cervical traction device 2 of the present invention is mainly composed of a single belt 1 and a length adjusting member 10, and the length adjusting member 10 is moved up and down so that the traction direction and length of the cervical traction device 2 are increased. By arbitrarily setting the length, it is possible to distribute the pressure to the front and rear support parts and respond to all symptoms and the size of the head of the subject, so that the operability can be easily and easily used.

[0062] The cervical traction device 2 is configured as described above, and the support part of the cervical traction device 2 is not required for the lower jaw, but mainly for the lower edge of the occipital bone nodules, so there is little discomfort. The resting state of the muscles around the head and neck can be easily obtained. Therefore, the effect of cervical traction is significant. The Therefore, it is desirable to apply a weaker load than when using a conventional cervical traction orthosis. If the traction force is too strong or the pressure distribution to the front and rear support parts is wrong, the front and rear support parts will be painful. In particular, great care must be taken because compression on the pinna is painful.

[0063] Further, the posterior support portion of the cervical traction device 2 is also a portion corresponding to the muscles directly under the occipital bone, and moderate compression and relaxation produce a massage effect.

[0064] The cervical traction device 3 has a predetermined angle (backward inclined) of the backrest 11 of the chair 9 (

Θ) brings the subject's head and neck muscles to a resting state, and the headrest 12

By placing the subject's head in the desired position, the head and neck muscles are in a relaxed state at any time during towing and resting. In addition, a predetermined angle (Θ) of the cervical traction device 2

The difference in the predetermined angle (Θ) given to 1 and backrest 11 gives the cervical traction direction.

2

The surgeon's identification allows for more reliable and effective cervical traction.

FIG. 8 shows a further improvement of the cervical traction device 2 of the present invention. The cervical traction device 2 is assumed to have a substantially trapezoidal ring 24 having different left and right side lengths as shown in FIG. 9 interposed between the belts 1 on both sides of the subject.

[0066] The ring 24 is parallel to the left and right sides 24a, 24b, and the upper side 24c and the lower side 24d are inclined and tapered due to the difference in length between the sides 24a, 24b. The ring 24 is attached to the belt 1 on each side of the subject so that the upper side 24c is lowered rearward and the lower side 24d is raised rearward. The upper and lower ends of the middle of the belt 1 to which the ring 24 is attached are folded back so that the insertion part 25 of the upper side 24c and the lower side 24d of the ring 24 is formed inside, respectively, by sewing, bonding, metal fittings 26, etc. It is fixed. The upper side 24c and the lower side 24d of the ring 24 are rotatable at the insertion portion 25, respectively.

[0067] As shown in FIG. 1 to FIG. 3, the belt 1 extending in the left and right direction near the upper cervical vertebral surface sandwiches the head, falls forward and upward, and is connected to the hook 8. A taper-shaped force that narrows upward when viewed from the front of the subject.Because the ring 24 is provided between the belts 1 on both sides of the subject, the belt 1 has front and inner sides of the subject's head (both sides of the head). The force to move the belt 1 in the direction in which the distance between the belts 1 is reduced) increases the function of preventing the belt 1 from detaching from the subject's head! /. Further, the cervical traction device 2 is provided with a occipital support band portion 27 as shown in FIG. 10 on the belt 1. The occipital support band 27 is a combination of the left and right temporal bone support portions 27a, 27b and the central occipital bone support portion 27c, and each end of the belt 1 on both sides of the subject has left and right temporal bone support portions. 27a and 27b are rotatably attached by metal fittings 28.

[0069] The temporal bone support portions 27a and 27b have a width larger than that of the belt 1, and the occipital bone support portion 27c has the same width as that of the belt 1, and the temporal bone support portions 27a and 27b have a larger area. Fits well, so the cervical traction device 2 is more stable and comfortable to use.

[0070] The cervical traction device 2 may be configured such that either the ring 24 or the occipital support band 27 is not provided. The cervical traction device 2 can be freely combined with the length adjusting member 10 and other components as appropriate.
