Description

Technical Field

[0001] The invention belongs to the technical field of transport devices, and in particular relates to a transport device suitable for patients with craniocerebral trauma. Background Art

[0002] Craniocerebral combat trauma refers to open or closed craniocerebral injury caused by external violent impact to the brain due to explosions of military weapons during war. Craniocerebral injury may also occur in some traffic accidents and falls from heights. Craniocerebral injury is a critical condition and progresses rapidly. It is prone to skull fractures, intracranial hematomas, intracranial hypertension and even brain herniation, which is life-threatening and is one of the leading causes of death and disability worldwide. Safe, timely and effective transportation plays an important role in treatment and prognosis. Patients on craniocerebral combat beds need to pay attention to protecting their heads during transportation. If they are bumpy, shaken or vibrated during transportation, it will affect the patient's circulation and respiratory function on the one hand, and on the other hand, it may aggravate cerebral edema or cause intracranial hemorrhage, acute increase in intracranial pressure, and lead to the patient's death.

[0003] At present, when transporting patients with craniocerebral trauma, it is necessary to use a transport vehicle or a stretcher to transport the patient to an ambulance, and then the ambulance will transport the patient to a hospital for further treatment. However, in the field, the geographical environment is complex. If only a stretcher is used, it will cause a large workload for the transport personnel. If a transport vehicle is used for transportation, it may be difficult to move forward when encountering a bumpy road, and the patient's treatment time will be prolonged, which is very likely to cause irreversible results. At the same time, the existing transport vehicle or stretcher fixes the patient's head by setting splints on both sides of the headrest, and the height of the splint is much higher than the height of the headrest. The transport personnel need to lift the patient to a position higher than the upper end of the splint and then put the patient's head and body down, and put the patient's head accurately between the two splints. Such an operation is relatively time-consuming and physically demanding, especially in an emergency such as a field battle, the patient's head may hit the raised splint, which will not only cause the patient to suffer secondary trauma, but also cause a large burden on the transport personnel.

[0004] In summary, there is an urgent need to design a transport device suitable for patients with craniocerebral trauma that overcomes the above-mentioned problems. Summary of the invention
