Description

  The present invention relates to a cervical spine, and more particularly, to a cervical spine that stably holds the occipital region in the treatment of a cervical spine injury disease, thereby maintaining a proper cervical posture.

  The cervical spine has been developed for posture correction to the neutral state of the spine, and a front support body having a chin rest and a support body formed to receive the occipital region are belt-fixed, Further, there is known a configuration in which the head posture is stably maintained by being fixed to the forehead with a belt provided on the back head support portion.

As a conventional technique of such occipital support type cervical vertebrae, for example, the following documents can be cited.
6-3311

In such a cervical spine orthosis, the support body is usually formed of a hard synthetic resin, and a structure in which the support body is positioned on the back and fixed to the body with a belt is employed.
The upper back support portion of the support is also integrally formed of synthetic resin, and is curved so that the back head can be conveniently received. The rear head support portion is provided with a belt-like body so that the head can be firmly fixed by being hung on the front head.

A stable posture can be maintained by fitting the occipital region by the occipital region supporting portion like this, but when a cervical vertebra disease therapist lies on the back, when supporting the heavy head, Depending on the shape of the head and the supine posture, the pressure is locally concentrated.
As a result, even in a relatively short time, the head feels pain and cannot sleep.
In order to solve such a problem, a measure is taken to reduce the shift load by attaching a cushion material to the inside of the occipital head support portion and receiving the head portion.

However, even if a cushion material such as sponge or felt is arranged, the weight of the head is very large, so the cushion material is locally compressed depending on the shape of the head or the supine posture to On the other hand, the occipital region is directly perceived, but it feels like pain.
However, it is possible to increase the thickness of the cushioning material, but having a thickness sufficient to disperse the head load will lead to an unstable head posture, and air permeability. It was found to be unfavorable because of the damage.

  In view of such problems, the present invention provides a cervical orthosis as described above, in which the head posture can be stabilized and the cervical spine disease can be treated while avoiding the occurrence of pain in the occipital region even in the supine posture. With the goal.

In order to achieve the above object, the cervical spine according to the present invention receives the back of the head and stabilizes the posture even when the posture is shifted to the supine posture, and the body support member (1) extends from the back to the back of the head to protect the cervical spine. And a plurality of belt-like members (2) for fixing the main body support member (1) to the chest, neck and chin of the body , and the rear head support portion (1A) of the main body support member (1) surrounds the rear head In the cervical orthosis, wherein the occipital region supporting portion (1A) is provided with a cushion member (3) that directly contacts the occipital region,
The occipital region receiving member (4) receives the pressure concentration of the occipital region due to the posture displacement in a distributed manner, and the curved surface (1a) of the occipital region receiving member (4) and the occipital region supporting portion (1A) and the maximum width is 15 mm. A thin 2 mm thin plastic that is arranged inside the occipital region supporting portion (1A) with an interval and is made of a thin synthetic resin and formed in a substantially lattice shape in a plan view and can be deformed according to the pressure displacement of the occipital region. , thus configured to substantially grid-like polyethylene material of the band width 4mm in plan view, and,
The occipital region receiving member (4) is fixed at the side edge of the upper end portion of the occipital region supporting portion (1A) and the side edge portion near the neck .
It is characterized by that.

The cervical spine according to the present invention is a device that is attached to a human body (back), supports the head in an appropriate posture, corrects the spine to a correct posture (arranged state), and treats cervical spine diseases. say. Of course, the case where it comprises the whole with the combination with the cervical vertebra orthosis which mounts a jaw part is also included.
The main body support member (1) is basically made of synthetic resin, but any material can be used as long as it has strength such as FRP or metal.
The cushion member (3) may be made of foamed resin such as urethane, non-woven fabric, or other materials generally used as cushion materials.

According to the cervical vertebra according to the present invention, when a cervical spine disease treatment patient wears the brace and lies on his back, the cervical vertebra is a cervical vertebra having a conventional configuration due to a head posture or a head shape. The situation where a load (due to the head's own weight) is locally applied to the occipital region supporting part to cause a situation that causes pain in a part of the occipital region is provided at a distance from the occipital region supporting part. Furthermore, the occipital region receiving member can disperse and receive the load of the local concentration on the occipital region due to the posture displacement, and by avoiding the concentration of the load on the occipital region locally, there is a remarkable effect that the occurrence of pain can be prevented, The patient has been able to continue treatment for cervical spine disease even in a posture.
In the present invention, the cushion material is used, but this is for the purpose of performing a buffering function for softly receiving the back of the head, and does not serve the purpose of dispersing the above-mentioned local load (due to the head's own weight). .
Other effects according to the present invention will be apparent from the following description of examples.
