Description
Technical Field
The utility model relates to the field of medical examination auxiliary tools, in particular to a CT examination auxiliary device.
Background
The enhanced CT and CT angiography technology is a technology for discovering and diagnosing pathological changes by utilizing contrast change of normal tissues and abnormal tissues of blood vessels or target organs in different degrees on CT and different black-white changes on final images when iodine contrast agent flows through the blood vessels and the target organs after intravenous injection. The method is widely used for disease localization, characterization, evaluation after treatment and the like in clinic. However, in the practice of CT examination, the blood vessel display and the enhancement and strengthening effect of the target organ of some patients are not good. This is mainly due to the obstruction of upper arm venous return. In this case, the speed and concentration of the iodine contrast agent do not meet the diagnostic requirements, so that the patient cannot diagnose, the money and time of the patient are wasted, and the treatment is delayed or unnecessarily changed, thereby affecting the accurate treatment of the patient. In general, both enhanced CT and CT angiography techniques inject an iodine contrast agent intravenously into the upper arm, which flows back from the vein to the heart and then from the artery to the target organ. At the moment, the patient needs to lift the upper arm over the head to avoid the artifacts formed by the arm to the chest and abdomen, the lifting angle of the upper arm is more between 160 and 180 degrees, the clavicle and the 1 st rib are easily formed to press the vein of the upper arm, the lumen is narrow, the venous reflux is blocked, and the effect of enhancing CT and CT angiography is influenced. However, we have observed that when the angle of the upper arm of the patient is adjusted to 120-.
