Control bar 42 is connected, the other end comprises a connecting bar 43, the third support 41 is installed.

On the other hand, a portion of the above-described third support 41 is interviewed in the patient's back of the head is provided with a silicon pack 50 is adjustable volume, the silicon pack 50 is the first support 11 and the second described above The same description as that provided with the support 23 will be omitted.

Hereinafter, the overall use method for the cervical spine fixing device 1 according to an embodiment of the present invention will be described.

First, the person who wears the cervical spine fixing device 1 presses the stop members 14b, 32b, and 34b of each of the first ratchet mechanism 14, the second ratchet mechanism 32, and the third ratchet mechanism 34. Engaging projections 12, 22, 44 of the fastening tube 12, the first length adjusting bar 21, and the second length adjusting bar 42 on which the ends of the stop members 14b, 32b, and 34b that are bent are hung. In order to be separated from, the first length adjusting bar 21 of the shoulder shoulder portion 20 to be introduced into the fastening tube 12, and the rotating tube 31 of the link member 30 is rotated to the outside, The second length adjusting bar 42 of the rear head fixing part 40 is moved backward.

In this state, the first support 11 is fixed to the jaw of the patient, and the fastening tube (1) is not pulled out until the first length adjustment bar 21 is no longer pulled out so that the second support 23 is closely attached to the shoulder. 12) Withdraw in.

At this time, the first length adjusting bar 21 drawn out is fastened by the stop member 14b of the first ratchet mechanism 14 to the engaging protrusion 13 of the fastening tube 12 and is firmly fixed without being retracted by external force. At the same time, the first support 11 is angled to fit the size of the patient's jaw as the hinge tube 12 is hinged to adjust the angle.

When the first support 11 and the second support 23 are tightly fixed to the jaw and shoulders of the patient, the pivoting tube 31 of the link member 30 is rotated inward until it is no longer pivoted, wherein the inner Rotating tube 31 is rotated to be caught by the stop member (32b) of the second ratchet mechanism 32 to be firmly fixed without being rotated outward again by an external force.

Then, the second length adjustment bar 42 is moved forward until the third support 41 is fixed to the back of the patient's back of the head and no longer moved, wherein the second length adjustment bar ( 42 is caught by the stop member 34b of the third ratchet mechanism 34 and is firmly fixed without being moved backward by an external force.

Then, a syringe is inserted into the inlet of the silicon pack 50 of the first support 11, the second support 23, and the third support 41, which is in close contact with the patient's jaw, shoulder and back of the head. Injects air so that the jaw, shoulder and back of the head are closely contacted with the first support 11, the second support 23, and the third support 41 without being spaced apart.

Patients whose jaw, shoulder, and larynx are fixed by the first support 11, the second support 23, and the third support 41 can firmly fix the cervical vertebra so that secondary injury can be completely prevented. This process can be carried out quickly and accurately alone without skilled expertise.

The method of disassembling the cervical vertebrae fixing device 1 worn by the patient is similar to the first step for wearing the cervical vertebral locking device 1, and the first ratchet mechanism 14, the second ratchet mechanism 32, and the third A fastening tube 12, a first length adjusting bar 21 on which end portions of the stop members 14b, 32b, and 34b which are bent by pressing the stop members 14b, 32b, and 34b of the ratchet mechanism 34 are caught. The first length adjusting bar 21 of the shoulder strap 20 is drawn into the fastening pipe 12 by being separated from the locking protrusions 13, 22, 44 of the second length adjusting bar 42. The rotating tube 31 of the link member 30 is rotated to the outside, and the second length adjusting bar 42 of the posterior head fixing portion 40 can be easily removed from the patient's body in a state of moving backward. .

As described above, the cervical spine fixing device according to the present invention can be worn by adjusting the length and direction of the support for each of the jaw, shoulder and back of the head to adjust the length and direction to fit the patient's condition and body shape to apply to a variety of patients as a single device There is an excellent effect that can be used.

In addition, the method is easy and convenient to use and can be quickly and accurately worn alone without skilled expertise, which has the advantage of transporting the patient to a safe state within a short time.
