Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an arm raising auxiliary fixing device used for magnetic resonance imaging. Background Art
[0002] With the development of medical technology, the application of medical imaging technology in diagnosis and treatment can significantly improve the diagnosis rate of diseases. By scanning the human body through rays, it can clearly reflect the human tissue and internal anatomical structure. It can clearly reflect the lesions and has important value for the development of medical imaging.
[0003] Magnetic resonance imaging (MRI) is a safe examination method without ionizing radiation, which performs multi-parameter imaging based on the different proton content and relaxation time of different tissues in the human body. For some patients whose lesion range and nature are difficult to determine, in order to obtain clearer imaging data, it is necessary to inject paramagnetic contrast agents into the patient's vein during the examination to improve the contrast of the imaging and the accuracy of the diagnosis.
[0004] At the same time, when conducting MRI examinations of the chest and abdomen, since there will be some overlap between the arms and other limbs and the body, the overlapping parts are prone to produce curling artifacts during scanning, resulting in poor imaging quality. In order to solve the problem of some overlap between the arms and other limbs and the body, medical staff will ask patients to raise their arms during the test to avoid some overlap between the arms and other limbs and the body, thereby improving the imaging quality. Raising the arms for a long time will cause soreness and other discomforts, and then produce motion artifacts. Therefore, it is urgent to improve the comfort of arm placement. In addition, examinations of the chest and abdomen require the use of respiratory gating, and the respiratory gating tube will rub against the inner wall of the MRI and affect its use. In addition, for some patients who need enhanced scanning examinations, it is necessary to inject contrast agent intravenously through a high-pressure syringe while scanning. During the injection process, the indwelling needle is generally left in the patient's upper limbs and other positions. Therefore, there is an urgent need for an arm-raising auxiliary fixation device to prevent the injection line from twisting or the injection needle from falling off due to the patient's limb bending or movement during enhanced scanning examinations, ensure the patency of the high-pressure injector line, avoid adverse reactions such as drug extravasation, greatly improve the success rate of enhanced scanning examinations, and increase patient comfort.
