Description
Technical Field
The invention belongs to the field of wheelchairs, and particularly relates to a multifunctional wheelchair for nuclear magnetic resonance examination.
Background
Nuclear magnetic resonance is an increasingly important examination method in imaging departments, is the most effective imaging diagnosis method for diseases such as craniocerebral and spinal cord, and can not only discover tumors, cerebral infarction, cerebral hemorrhage, brain abscess, encephalocytosis and congenital cerebrovascular malformation at early stage, but also determine the type and reason of hydrocephalus. Aiming at the breast cancer which is the first major gynecological disease harmful to the life health of Chinese females, the nuclear magnetic resonance precise screening can help to find the early focus of the breast cancer; for the population suffering from hypertension, hyperlipidemia and hyperglycemia, the potential risks of high-risk diseases such as heart disease, cerebral infarction and the like can be discovered early before the body health gives out a red light warning signal through nuclear magnetic examination of the head, the heart and the like. In addition, the nuclear magnetic resonance can also be used for examining the abdomen and the pelvic cavity, such as the liver, the gall bladder, the pancreas, the uterus and the like, and the imaging of the abdominal great vessels and the blood vessels of the limbs can clearly diagnose various pathological changes of true aneurysm, false aneurysm, sandwich aneurysm and the blood vessels of the limbs. The nuclear magnetic resonance has very fine diagnosis on various joint tissue lesions and is very sensitive to aseptic necrosis of bone marrow and bones. The method has the advantages of clear imaging, no radiation, wide disease detection range, no influence on human health and the like.
However, since the core component in nuclear magnetic resonance is a superconducting magnet, magnetic articles and metals such as mobile phones may affect the inspection effect, the nuclear magnetic resonance is not allowed to be brought into a nuclear magnetic resonance inspection room, and particularly, the metal containing iron is directly adsorbed on the magnet. Almost all medical wheelchairs in the market at present are formed by welding steel, and the wheelchair is pushed into a magnetic resonance examination room at home and abroad to be adsorbed on a magnet.
At present, for patients who are similar to patients who have cerebral infarction, cerebral hemorrhage, fracture and the like and are difficult to walk by depending on wheelchairs, at the present stage, the wheelchairs can only be pushed out of an examination room during nuclear magnetic resonance examination, then a plurality of family members support or lift the patients to a nuclear magnetic resonance examination bed, the risk in the carrying process is high, the patients can fall down and be injured at any time, and even secondary injury can be caused by improper operation of the family members in the carrying process. At present, no medical wheelchair specially used for nuclear magnetic resonance examination appears, and the examination risk of a patient is undoubtedly increased by using the conventional method.
