Description

  The present invention relates to a cervical traction device for attaching to a patient and applying traction force to the cervical spine for cervical traction treatment for alleviating neck pain associated with cervical vertebral disorders such as cervical spondylosis and cervical disc herniation.

As this type of cervical traction device, for example, a cervical traction band disclosed in Patent Document 1 is widely known. That is, the cervical vertebra traction band disclosed in Patent Document 1 is mounted in a state of being in contact with the patient's head and jaw, and is configured to pull the cervical vertebra by applying traction force to the patient's occipital region and lower jaw.
However, when a traction force acts on the lower jaw, the traction force also acts on the teeth and temporomandibular joints meshed with each other, which may cause damage and pain to the teeth and temporomandibular joints.
In order to solve such a problem, Patent Document 2 discloses a cervical traction device including a belt that pulls both heads from the back of the patient (subject).
However, the cervical traction device disclosed in Patent Document 2 has a configuration in which a traction force is applied by inserting a belt into the lower lower edge of the patient's skull as shown in FIG. Tends to detach from the patient's skull. Therefore, it was necessary to tilt the patient's torso backward rather than the direction of action of the traction force and perform traction in a posture in which the weight of the patient's head acts on the belt (see FIG. 1 of the same document 2). The paragraph “0034” of the same document 2 states that “If the supporting portion of the cervical traction device 2 is obtained only at the lower part of the occipital nodule, sufficient fixation cannot be obtained and the cervical traction device 2 may be detached. It is clearly stated.

And the fastening parts 11 a and 12 a provided at both end parts 11 and 12 of the appliance main body 10.

  The orthosis main body 10 is rod-shaped, and is curved and formed in a mountain shape with the central portion applied to the patient's back of the head as the top. And it is the structure which fastens the both ends 11 and 12 with a forehead from a patient's occipital region via both heads, and attaches to a patient (refer to Drawing 4).

  As shown in FIG. 3, the appliance main body 10 has a main body surface formed by an inner surface member 13 and an outer surface member 14. A cushion member 15 is filled in the hollow portion surrounded by the inner surface member 13 and the outer surface member 14.

  The inner surface member 13 directly contacts the patient's head and has a function of holding the appliance main body 10 with frictional resistance generated between the inner surface member 13 and the patient's head. Therefore, the inner surface member 13 is made of a material having a large friction coefficient and flexibility. By using a material having a large friction coefficient, the patient's head can be firmly held. Furthermore, by using a flexible material, it is possible to closely contact the patient's head and to gently hold the patient's head.

  In the conventional cervical traction device, the surface in contact with the patient is generally formed of felt (nonwoven fabric), but in the present embodiment, a material having a friction coefficient larger than that of the felt is used. Specifically, the inner surface member 13 is preferably formed of a chloroprene rubber material containing bubbles inside. This material is a rubber material used for wet suits, etc., which has a very large surface friction coefficient and flexibility, has a characteristic that it adheres closely to the human body and creates a large frictional resistance with the human body when traction force is applied. Have.

  Furthermore, the surface of the inner surface member 13 has a large number of irregularities to increase the surface area. When the inner surface member 13 is attached to the patient's head, the convex portion is crushed and closely contacts the patient's head. And when tractive force acts, friction resistance arises in each of these convex parts, and big friction resistance arises comprehensively.

  By configuring the inner surface member 13 in this manner, the holding of the patient's head by the appliance main body 10 can be made stronger.

  In addition, a cloth material having low stretchability is pasted on the back surface of the inner surface member 13 to reduce the elongation due to the action of the traction force. By reducing the elongation of the inner surface member 13 as described above, it is possible to suppress the displacement due to the deformation of the appliance main body 10 due to the traction force action.

  The outer surface member 14 has a function of suppressing the deformation of the appliance main body 10 against the action of the traction force and appropriately transmitting the traction force to the patient's head via the appliance main body 10. For this purpose, the outer surface member 14 is formed of a leather material that has low elasticity and flexibility, and has strength to receive traction. For example, a thick cowhide material used for a baseball glove is a suitable material for the outer surface member 14.

  In the present embodiment, an inner surface member 13 made of a chloroprene rubber material containing bubbles inside and an outer surface member 14 made of a cowhide material are overlapped, a cushion member 15 is put inside, and the inner surface member 13 and the outer surface member are placed outside. The orthosis body 10 is manufactured by sewing the edge of the surface member 14.

In addition to the polyester cotton, the cushion member 15 may be made of, for example, highly repulsive urethane or multilayered urethane as a material. Here, as a multilayer structure urethane, the thing of the structure which laminated | stacked chip | tip urethane, hard urethane, and soft urethane is suitable.

  In the present embodiment, both end portions 11 and 12 of the appliance main body 10 are formed of the same material as the inner surface member 13, and fasteners such as hook-and-loop fasteners are attached to the both end portions 11 and 12, and the fastening portions 11 a and 12 a. Is configured. These both ends 11 and 12 hold | maintain the said site | part against a patient's forehead (refer FIG. 4). The forehead is sensitive among the human head to which the orthosis body 10 is mounted, and is a site where pain is easily felt due to the contact of the orthosis body 10. Therefore, both ends 11 and 12 of the appliance body 10 are configured to gently hold the patient's forehead using a flexible material.

The pair of lifting portions 20 are provided in the appliance main body 10 by bending a belt material 22 having a strength capable of withstanding traction force into a U shape and sewing both ends of the belt material 22 to the outer surface member 14 of the appliance main body 10. Yes. And the ring-shaped hanging metal fitting 21 is inserted and attached to the belt raw material 22 bent in the U-shape.
The pair of lifting portions 20 are configured to extend above the orthosis body 10 from a portion that contacts the left and right sides of the patient's forehead while the orthosis body 10 is attached to the patient.

  As shown in FIG. 4, the cervical traction device according to this embodiment having the above-described configuration is wound around the device main body 10 from the back of the patient via the both sides of the patient, and both ends of the device main body 10 at the patient's forehead. By fastening 11 and 12, the orthosis body 10 is mounted on the patient's head. The appliance main body 10 thus mounted can firmly hold the patient's head over the entire circumference and is not easily detached even when the traction force P is applied.

  Here, the traction force P is transmitted from diagonally upward on the front side of the patient's head via a traction rope that is hooked to the suspension fitting 21 of the lifting portion 20. In addition, it is good also as a structure which abbreviate | omits the suspension metal fitting 21 and hooks a tow rope on the belt raw material 22. FIG.

Furthermore, the central portion of the orthosis main body 10 against the patient's occipital region is curved and formed in a mountain shape (see FIG. 1), so that the central portion of the lower edge 10a, which is concave upward, fits along the patient's neck. Can be made. And the state where the lower edge 10a of the orthosis main body 10 is hooked on the patient's neck 1a (that is, the lower rear edge of the skull) is formed by the pulling force P acting from the obliquely upper front side of the patient's head. The head is held more firmly.
In addition, since the main body 10 causes the traction force P to act on a wide area from the patient's neck 1a to the occipital region to generate a large frictional force, the patient's head can be more firmly held.
