Technical field

One or more example of the present invention is usually directed to armarium, especially relates to the health positioner of rigidity.

Background technology

With regard to Accurate Diagnosis, the vertebra in the radiography process develops (including but not limited to X-ray, fluoroscopy, CT etc.) must be accurately.Generally, patient's shoulder can be covered the side imaging of neck bone.This radiography development is to optimize by the afterbody displacement (towards the direction of foot) of immobilized patients shoulder, does not preferably interfere incidence to be fixed.Usually, the currently used realization cervical region of the clinician traditional method of location of developing accurately is included in and in the live radiography process patient's incidence is obviously located and process, and perhaps patient's arm and shoulder is positioned and controls.When these structures of location, bring risk can for the fixed structure of head and neck.Generally, the practitioner is concerned about the risk that increases the weight of any existing damage very much.

Cervical spine injury is the easiest unheeded major injury, and cervical spine injury may have very important implication to patient and doctor.Emergency room Rio 5-10% is because of motor vehicle accident or fall down the cervical vertebra that causes the patient who remains unconscious and major injury all occurred.On the sports ground most calamitous sick and wounded all be cervical spine injury.Cervical spine injury may be catastrophic damage, and according to estimates, in the U.S., the every annual meeting of cervical spine injury causes 6000 people and loses life, causes 5000 people's quadriplegia.

The standard skeleton of cervical vertebra forms by disc separation and by the continuous neck bone of the ligament network of complexity by 7.These ligaments make each piece bone come work as a unit.Cervical spine injury is classified according to several damage mechanism best.These damage mechanism comprise flexion injury, the damage of flexing rotatory, and the rotatory damage is stretched in the extensibility damage, vertical compression damage, the mechanism of lateroflexion damage and the not accurate understanding that may cause the dislocation of odontoid fracture and atlanto-occipital joint.

It below is the instantiation under the prior art, this example is to formerly the other side of technology is helpful further education reader, but do not refer to the present invention or any embodiment of the present invention are restricted to the application present patent application defined, hint or that infer.Under education background, what usually help to recognize prior art is on the other hand, because further complicated danger can occur at any time, for the doubtful patient who suffers from cervical spine injury, transport protocol requirement quotidian and that accept is lain on the back the patient and is fixed on on the backboard or long slab with semi-rigid neck-protection strap, support head and neck by the various belts across forehead, the from the side head and neck of immobilized patients is come in the location of the piece by sandbag or various foam or other form, triangle, liner, neck ring etc. simultaneously.Except tying up head, preferably shoulder and pelvis are also tied up, in case cervical region becomes the center of health rotation.Usually can be fixed up cervical vertebra, until the damage elimination in should the zone.Usually also can be fixed up patient's cervical region, until in radiation chamber, can see complete neck bone.If it is impaired that the patient is head, then usually can take preventive measures to cervical vertebra, until showing, radiography got rid of spinal injury fully.

The cervical vertebra radiography almost is the conventional way in the emergency room, yet also there is certain limitation in the cervical vertebra radiography.It is believed that, approximately the cervical spine injury of 85-90% is apparent in view in the radiography side view, is the most useful clinically view.Technical acceptable side view shows that usually these seven vertebral bodys and cervical spine breast section, C7-T1 gap make the arrangement of C7 and T1 become visual.Yet the fracture up to 20% is considered to lose in the plain film photograph.It is believed that, lose or the common cause of ignoring fracture of cervical vertebra, subluxation or dislocation damage is that the cervical vertebra radiography techniques is not mature enough.Usually, one of successful standard can obtain exactly all views and can see all vertebras.People can expect, do not manifest sickness rate that these zones may cause patient Geng Gao fully and to the malpractice suit of emergency physicians.

It below is the instantiation under the prior art, this example is to formerly the other side of technology is helpful further education reader, but do not refer to the present invention or any embodiment of the present invention are restricted to the application present patent application defined, hint or that infer.Under education background, what usually help to recognize prior art is it is believed that on the other hand, during radiography, 7 vertebras and C7-T1 junction are sightless, and the arm loss is non-existent, and the arm traction may help to see this 7 neck bones at lateral projection.The arm traction can affect the displacement of shoulder, thereby alleviates the pseudo-shadow of radiography that shoulder causes, and the pseudo-shadow of radiography can be covered the visual of the best.Yet traction is normally directly implemented on patient's arm by the office worker, or comes tractive patient's arm with band or binder, and this just means that these office workers must be on the scene during radiography, and can be subject to the radiation of ray.If arm does not damage, normally head (being commonly referred to " swimmer's view ") carries out ray side in the situation that arm extends through to scanning.It is visual fully that this technology can make cervical vertebra have.The practitioner pays much attention to the wound situation of initial damage, with the injured and fracture of avoiding arm usually to occur.In addition, owing to during radiodiagnosis, must patient's head and neck be completely fixed with foam bubble or sandbag, purpose for roentgenodiagnosis, to shoulder carry out push-and-pull or the measure of pressing all unfavorable because necessary fixture is interfered in these measure meetings, and may further damage the patient.

It below is the instantiation under the prior art, this example is to formerly the other side of technology is helpful further education reader, but do not refer to the present invention or any embodiment of the present invention are restricted to the application present patent application defined, hint or that infer.Under education background, what usually help to recognize prior art is on the other hand, study when nuclear magnetic resonance is used as the adnexa of plain film and CT scan when some, the shortage of wide usability has just limited its effectiveness acute the phase of adjustment with the needed relative very long time of nuclear magnetic resonance.Usually another aspect of considering is, may can not normal operation in the magnetic field that magnetic resonance imaging produces with the first-aid apparatus of hardware.To the magnetic resonance imaging of the ventilated patient arduous task of part normally, often need to use special nonferromagnetic equipment.Usually, for the purpose of diagnosis, it all is unpractical in many cases that the patient of doubtful neck bone subluxation is carried out nuclear magnetic resonance.

It below is the instantiation under the prior art, this example is to formerly the other side of technology is helpful further education reader, but do not refer to the present invention or any embodiment of the present invention are restricted to the application present patent application defined, hint or that infer.Under education background, what usually help to recognize prior art is on the other hand, and the current alternate manner that roentgenodiagnosis is carried out in subluxation to doubtful cervical vertebra post comprises the passive Dynamic Buckling of the perspective to cervical vertebra of being implemented by experienced clinician/stretching, extension.It is believed that, their result of study has been reported in some research centers, and some guilding principles are to using dynamic penetrating to support in the patient's who remains unconscious vertebra gap.It is generally acknowledged, carry out conventional flexing/be extended into picture in the intensive care unit and have very large difficulty, for the consideration of safety, a lot of spinal surgeon are unwilling to implement flexing/stretching,s extension and are operated.It is believed that, worsened the report of the case of (comprising quadriplegia) relevant for function of nervous system.

In sum, obviously, these traditional modes are also imperfect, and stayed the space for the more best approach.
